Description

  The present invention relates to a mold apparatus for processing a pipe material, and particularly relates to an inner mold apparatus that is inserted and arranged inside the pipe material and an outer mold apparatus that is arranged outside the pipe material, Further, the present invention relates to a pipe material drilling apparatus using the mold apparatus.

  Conventionally, when drilling or the like is performed on a pipe material, the processing is performed by the cooperative action of an outer mold device disposed outside the pipe material and an inner mold device inserted and disposed inside the pipe material. ing.

  As shown in FIG. 6, the conventional inner die device inserted and arranged inside the pipe material w is a ball 64 biased by the force of a spring 63 on one side w2 in the direction intersecting the side w1 to be processed. There is a mechanism in which a pressing mechanism is provided so that the punch 65 of the outer mold apparatus and the die 66 of the inner mold apparatus are positioned coaxially. In the figure, 61 is an upper block of the inner mold apparatus, and 62 is a lower block. Such coaxial positioning of the conventional outer mold device and the inner mold device is performed by using the side w2 that faces the inner mold device inserted into the pipe material w with reference to the inner surface of the pipe material w on the side w3 side. The inner surface of this was pressed with a ball 64 for positioning. For this reason, it is necessary to adjust the position of the reference block 67 every time the thickness dimension of the pipe material w changes.

  Further, in such a conventional mold apparatus, in order to press one of the sides w2 in the direction intersecting with the side w1 to be processed by the pipe material w with the ball 64 biased by the force of the spring 63, the side on which the ball 64 comes into contact Since the outer dimension of the inner mold device to be inserted is larger than the inner dimension of the pipe material w between the two sides of the side w3 opposite to the side w2, the inner mold device is connected to the pipe material w from the opening end surface portion of the pipe material w. When inserting into the interior of the, there was a problem that a large force was required and it was difficult to insert. In particular, when there is a burr toward the inside of the opening end face, it becomes more difficult to insert. In addition, there is a gap t between the pipe material w and the die 66 of the mold apparatus, and not only the burrs are generated by the drilling process, but also the drilled hole shape is distorted and is not an accurate shape.

  As described above, the conventional mold apparatus has a problem that it is difficult to detect this situation when the ball 64 malfunctions due to the force of the spring 63 and the movement of the ball 64. .

  In view of the prior art as described above, the present invention not only allows the inner mold apparatus to be easily inserted into the pipe material even when there is a burr facing inward on the opening end surface of the pipe material to be processed. The positioning of the mold device and the inner mold device is easily and reliably performed, and the coaxial adjustment work between the outer mold device and the inner mold device is not required, and the pipe material is drilled by the mold device of the present invention. It is an object of the present invention to provide a mold apparatus that facilitates processing of scrap generated by the above.

The mold apparatus of the first invention made for the purpose of solving the above problems has the following characteristics.
Pipe material processing comprising an outer mold device arranged outside the pipe material and an inner mold device inserted into the pipe material and working on the pipe material in cooperation with the mold of the outer mold device Mold equipment for
The outer mold apparatus includes a pilot mold that performs concentric positioning in the left-right direction with the inner mold apparatus and the outer mold apparatus.

According to the mold apparatus of the first invention, the following effects are exhibited. The outer die device arranged outside the pipe material to be drilled and the inner die device inside the pipe material are the inner die device provided by the pilot die provided in the outer die device before drilling. Therefore, the pipe material can be reliably positioned in the width direction. Therefore, it is possible to stably drill a hole at an appropriate position of the pipe material. If there is no pilot mold, the right and left concentricity of the mold cannot be secured, and stable machining cannot be performed.
Further, according to the mold apparatus of the first invention, effects such as improvement of the life of the mold, reduction of burrs on the inner surface side of the pipe material, and less distortion of the pipe material after processing are exhibited. Further, even if the thickness dimension of the pipe material changes, the coaxial adjustment work (adjustment of the reference block for positioning the pipe material, etc.) that is necessary in the case of the conventional mold apparatus becomes unnecessary.

The mold apparatus of the second invention has the following features in the first invention.
The inner mold apparatus is divided into two parts in the vertical direction of the inner mold apparatus so as to be reciprocally movable in the opening direction of the pipe material, and the reciprocating motion is A mechanism for expanding and contracting the inner die device in the vertical direction of the pipe member by converting it into a force that presses a portion of the inner die device that acts on the machining side into a working force is provided.

  According to the mold apparatus of the second invention, the inner mold apparatus inserted into the pipe material is provided with a fixing mechanism (hereinafter referred to as an expansion / contraction mechanism) by an expansion / contraction operation. Stable drilling is possible because it adheres firmly to the back of the material without any gaps. If there is no expansion / contraction function of the inner mold apparatus of the second invention, a gap is required to move the mold while inserted into the pipe material. If this gap is present, the burr on the back surface of the pipe material will be large during drilling, and distortion will increase. According to the expansion / contraction function of the inner mold apparatus of the second invention, since there is no gap at the time of drilling, the burr on the back surface is small, and drilling without distortion in the pipe material is possible.

  Also, when inserting the inner mold device from the opening end surface of the pipe material, by reducing the inner mold device in the vertical direction, the outer dimension of the inner mold device can be made smaller than the opening dimension of the pipe material, Insertion into a pipe material having burrs on the inner surface can also be easily performed.

The mold apparatus of the third invention has the following characteristics in the first invention or the second invention.
The scrap generated by drilling by the outer mold device and the inner mold device is accommodated in the inner mold device, and the lower portion of the inner mold device is prevented from contacting the inner surface of the pipe material. When opening the lid that can be opened and closed in the vertical direction, when discharging the stored scrap, by opening the lid provided in the inner mold apparatus at the time of separating the lid to a position that does not interfere with the pipe material, The lid itself forms a sliding surface for scrap and discharges the scrap.

  According to the mold apparatus of the third invention, the scrap (cass) generated by the drilling process is collected and processed inside the inner mold apparatus, so that the scrap is accommodated and processed without contacting the inner surface of the pipe. No residue is left inside the pipe material. Therefore, there is no need to remove the residue accumulated in the pipe after drilling the pipe material, and there is no clogging with the inner surface of the pipe material of the inner mold apparatus during processing, and stable processing is possible. Further, the waste accumulated in the inner mold apparatus can be automatically discharged every time the pipe material is replaced, and wasteful work by the operator is eliminated and productivity is improved.

The mold apparatus of the 4th invention has the following characteristics in the 3rd invention.
The lid is provided with a fulcrum for itself to rotate, and the force applied by the weight of the lid overcomes the force applied by the weight of the lid but is added with the weight of a certain amount of scrap accommodated in the inner mold apparatus. When the lid is closed by a losing spring force and there is no scrap, the spring force is always applied so that the lid is in close contact with the inner mold apparatus, and the weight of a certain amount of scrap accommodated in the inner mold apparatus In the state where is added, it is automatically opened when pulled away from the pipe material.

  According to the 4th invention, the same effect as the 3rd invention is expressed.

  A pipe material drilling device according to a fifth aspect of the invention is characterized in that the die device for processing a pipe material according to any of the first to fourth aspects of the invention is used.

  According to the fifth aspect, the same effect as in the first to third aspects is exhibited. Further, since the square pipe is drilled by the drilling apparatus using the mold apparatus according to the first to third inventions, the efficiency and accuracy of the drilling process are remarkably improved.

A drilling device for processing a pipe material according to a sixth aspect of the present invention has the following characteristics in the fifth aspect of the present invention.
The lid itself is provided with a fulcrum for rotational movement, and the lid is closed by a spring force that overcomes the force exerted by the weight of the scrap accommodated in the inner mold apparatus, and the spring force is applied to the lid. When the lid is opened downward, it is forcibly opened by a lid opening device provided in the drilling device main body separately from the mold device. .

The lid 29 is supported through a pin 30 so as to be rotatable in the vertical direction, and is provided so as to be in close contact with the lower surface of the inner mold apparatus 4 by a spring 31.

  The inner die device 4 is used in a state of being inserted inside a pipe material (hereinafter referred to as a square pipe W) which is a workpiece. The square pipe W is set toward the right side of FIG. 1 while inserting the inner mold device 4 from the left side of FIG. The inner mold device 4 is connected to a sliding drive device 10 disposed on the frame 9 and performs an expansion / contraction operation in the vertical direction of the inner mold device 4 by expansion and contraction of a cylinder 10a of the sliding drive device. The outer mold apparatus 3 is provided at the upper part of the press machine and moves up and down, and the inner mold apparatus 4 is supported by a work receiving portion 5 on a press base 8 at the lower part of the press machine 1.

  Further, the frame 9 on which the inner mold device 4 and the sliding drive device 10 are mounted is configured to be movable on the press base 8 to the position of the two-dot chain line in FIG. With this cylinder 12, the inner die device 4 operates a lid opening device 13 provided in the press machine to collect the scrap S (see FIG. 5) collected in the scrap accommodating portion 28 inside the inner die device 4. Move to a possible position.

<2> Square Pipe Drilling Method A square pipe drilling method will be described with reference to FIGS. 1 and 2. As described above, the square pipe W is set in a state in which the inner mold device 4 supported by the workpiece receiving portion 5 and the frame 9 of the press machine 1 is inserted. The length of the square pipe is 2m to 4m. The square pipe W into which the inner mold apparatus 4 is inserted is gripped by the clamp 14 at the end on the side opposite to the press machine. The clamp 14 is connected to a moving unit 15 on a guide 16 which is arranged on the press base 8 and linearly guides. This unit is formed by a positioning drive device 11 composed of a ball screw 17 and a servo motor 18 disposed on the press base 8, and a square pipe W is placed under the outer mold device 3 in the longitudinal direction. Position at the machining position.

  Positioning of the square pipe W in the width direction is performed as follows. As shown in the X arrow view of FIG. 2, a reference block 19 and a clamp cylinder 20 are provided on the work receiving portion 5 on the press base 8. The square pipe W positioned in the longitudinal direction by the positioning drive device 11 is pressed against the reference block 19 by the clamp cylinder 20, whereby the square pipe W is positioned in the width direction.

  The positioning control of the square pipe W, the control of the press device 2, the expansion / contraction control of the inner die device 4, the control of the sliding drive device 10, the control of the positioning drive device 11 and the clamp cylinder 20 are the controls shown in FIGS. This is done by the device 21. In addition, this control device also performs discharge control of scrap (punched waste) S generated by drilling, which will be described later. The square pipe W gripped by the clamp 14 is positioned with respect to the outer mold device 3 by the positioning drive device 11, and when the positioning is completed, the square pipe W is pressed against the reference block 19 by the clamp cylinder 20 and fixed to the press machine body 1. Thereafter, as shown in FIG. 3 (c), the outer die device 3 is lowered by the action of the press device 2, and the square pipe W is continuously drilled by the cooperative action with the inner die device 4, thereby A number of drilling operations are performed at a pitch specified for the pipe W. The square pipe W for which the drilling has been completed is moved and discharged to the outside of the press machine main body 1 (left side in FIG. 1) by the positioning drive device 11.

  The press machine is provided with a pilot die of the outer die device 3, which is a specific content of the present invention, an expansion / contraction mechanism of the inner die device, and a recovery mechanism for scrap S generated by processing. The contents of each invention will be described below with reference to the drawings.

<3> Configuration of Pilot Mold P of Outer Mold Device The pilot mold P is disposed in a portion corresponding to the A part in FIG. The pilot mold P will be described with reference to FIG.

  The pilot mold P is provided in the outer mold apparatus 3 separately from a processing mold (hereinafter referred to as a punch blade 25) for positioning the outer mold apparatus 3 and the inner mold apparatus 4. One or more pilot molds P may be provided. As shown in FIG. 3, the tip of the pilot mold P has a shape that can be easily inserted into the pilot hole H of the pilot mold of the inner mold apparatus 4. As for the dimensional relationship between the pilot mold P and the insertion hole H, the gap is large in the length direction of the pipe material, and the gap is approximately micron in the width direction of the pipe material. Further, the length of the pilot mold P of the outer mold apparatus is longer than the tip of the punching blade 25 for processing by about 5 mm. In this figure, two pilot molds P are provided in the pipe material width direction in order to position the outer mold apparatus 3 and the inner mold apparatus 4. Note that the method of arranging the pilot mold is not limited to this.

The pilot mold P operates as follows. The square pipe W to be processed is moved and positioned to a predetermined position to be processed by the positioning driving device 11, and the pilot mold P of the outer mold apparatus 3 is lowered from the state of FIG. Inserted. Thereafter, the expansion / contraction raising operation (details will be described in <4>) of the inner mold apparatus 4 is performed, and the state shown in FIG. At this time, the pilot mold P and the punch blade 25 are in a lowered state. However, since the pilot mold P is longer, it is inserted into the pilot hole H of the inner mold apparatus 4 first. Thereby, the inner mold apparatus 4 is positioned in the width direction of the outer mold apparatus 3 and the pipe material W. Thereafter, from the state of FIG. 3B (before the punch blade 25 is lowered), the punch blade 25 is lowered as shown in FIG.
By using such a pilot mold P, the coaxial positioning adjustment between the outer mold apparatus 3 and the inner mold apparatus 4 described in the prior art becomes unnecessary.

<4> Enlargement / Reduction Mechanism of Inner Mold Device The expansion / reduction mechanism of the inner mold device 4 is a portion corresponding to the portion B in FIG. This will be described with reference to FIG.

  The inner mold apparatus 4 is divided into an upper expansion / contraction block 41 and a lower expansion / contraction block 42. Both are configured to slide in contact with each other on a weakly tapered surface. The upper expansion / contraction block 41 is held on the work receiving portion 5 of the press so that the position of the horizontal method does not change and moves in the vertical direction. When the lower expansion / contraction block 42 is moved in the horizontal direction by the action of the cylinder 10a or the sliding drive device 10, the upper expansion / contraction block 41 is raised and lowered in the vertical direction. In this case, the upper expanding / contracting block has a hole 27 to be lifted so that the relative positions of the pilot die P and punch blade 25 of the outer die device with respect to the length direction of the pipe material do not change.

  The inner die device 4 functions in a form inserted inside the square pipe W that is a workpiece. The ascending operation of the upper expansion / contraction block 41 is as follows. The outer mold device 3 is lowered from the state of FIG. 4A, and the pilot mold P is also lowered, and the coaxial positioning between the outer mold device 3 and the inner mold device 4 is completed. Next, when the lower expansion / contraction block 42 is moved in the horizontal direction (arrow Y direction in FIG. 4 (a)) by the cylinder 10a (see FIGS. 1 and 2), the upper expansion / contraction block 41 is lifted by about 0.5 mm. ) And the gap T in FIG. FIG. 4B shows a state before the punch blade 25 is lowered (before drilling). As a result, the upper surface of the upper expansion / contraction block 41 and the lower surface of the lower expansion / contraction block 42 are in close contact with the upper and lower inner surfaces of the square pipe W. Thereafter, the punch blade 25 is lowered and drilling is performed.

  The lowering operation of the upper expansion / contraction block is as follows. FIG. 4C shows a state in which the punching blade 25 has been raised after the drilling process has been completed. At the same time as the outer mold apparatus 3 including the pilot mold P rises from the state of FIG. 4C, the cylinder 10a operates in the horizontal arrow Z direction of FIG. 4C. As a result, the upper expansion / contraction block 41 is lowered to the state shown in FIG. 4A, and the vertical size of the inner mold apparatus 4 is reduced to be smaller than the inner dimension of the square pipe, and to the next drilling position of the square pipe. It is also easy to move. Further, the inner mold device 4 can be easily inserted into the inside of a square pipe having a length of 2 m to 4 m. Also, during drilling, the expansion and contraction function ensures that the square pipe drilling part and the inner die device 4 are in close contact with each other, so that the occurrence of burrs is minimized, and the position accuracy of drilling is also higher than that of conventional machining methods. Will improve dramatically.

<5> Scrap Collection Mechanism The scrap collection mechanism operates in such a manner that the lid opening device 13 arranged in the portion corresponding to the portion C in FIG. 1 and the scrap accommodating portion 28 formed in the inner mold device in FIG. To do. The scrap collection mechanism in the present invention will be described with reference to FIG.

  The drilling of the square pipe W will be described again. First, when the press device 2 is lowered, the outer die device 3 and the stripper plate 23 are lowered, the stripper plate 23 is in contact with the upper surface of the square pipe W, and the press device 2 is lowered. Next, the strip spring 24 interposed between the stripper plate 23 and the punch plate 7 bends and presses the square pipe W by the reaction force, and the punch blade 25 bites on the upper surface of the square pipe W, Drilling is performed by the cooperative action of the cutting edge portion 26 and the punching hole 27 of the die device 4 (see FIG. 3C), and the scrap S separated from the square pipe W by this drilling processing is the inner metal. The mold device 4 is blocked by the lid 29 that contacts the lower surface of the lower expansion / contraction block 42 and accommodated in the scrap accommodating portion 28.

  The inner mold apparatus 4 is disposed on the frame 9. For the next drilling process, the square pipe W is positioned at the machining position by the positioning drive device 11. Thus, the square pipe W moves with respect to the inner mold apparatus 4 for drilling. Accordingly, the scrap S is blocked by the lid 29 and does not come into contact with the lower surface inside of the square pipe W.

  Next, the lid opening device 13 will be described. FIG. 5A shows a state in which the driving device 13a of the lid opening device 13 has been raised, and FIG. 5B shows a state in which the driving device 13a of the lid opening device 13 has been lowered. 33 is a pressing bar, and 34 is a scrap pushing member that forcibly pushes down the scrap S remaining in the punching hole 27 of the inner die device 4 after the drilling process is finished. The pressure bar 33 is provided with an air passage 35, and when the lid 29 is opened, air is blown out from the discharge port 36 at the tip of the air passage 35 to clean the upper surface of the lid 29 that becomes the sliding surface of the scrap S. At the same time, it is designed to assist the scrap S. On the other hand, the scrap pushing member 34 is provided with teeth 34a that can enter the cutting blade portion 26 (extracted hole 27) of the inner die device 4 when lowered, and scrap remaining in the cutting blade portion 26 (extracted hole 27). S can be discharged.

  When the drilling of the square pipe W is completed, or when a certain amount of scrap S is accumulated and discharged, the inner mold device 4 receives a drilling position (outer mold device) according to a command from the control device 21. 3) to the position as shown in FIG. The inner mold device 4 is fixed to the frame 9. The frame 9 can be moved by a cylinder 12 provided on the press base 8. The frame 9 is moved by a command from the control device 21, and the inner mold device 4 is moved and positioned to the position shown in FIG. 5 (that is, the position where the lid opening device can be operated). At this time, the finished square pipe W is discharged to the left side of the front view of FIG. Therefore, the lid opening device 13 and the square pipe W, which is a workpiece, do not interfere with each other.

  In this state, the lid opening device 13 operates. The operation will be described below. First, the lid opening device 13 is lowered by the driving device 13a to change from the state of FIG. 5A to the state of FIG. 5B. The pressing bar 33 is configured to be able to pass through the inner mold device 4, overcomes the force of the spring 31 that biases the lid 29, and pushes the lid 29 downward. As a result, the scrap S accommodated in the scrap accommodating portion 28 slides on the lid 29 and falls into the bucket 37. On the other hand, the scrap S remaining in the hole 27 of the inner die device 4 is pushed out by the scrap pushing member 34, slides on the lid 29 and falls into the bucket 37. By adding a function for detecting the height of the lowered position of the scrap pushing member 34, the discharge of the scrap S can be confirmed.

  In the above description, the square pipe W is operated with the lid opening device 13 in a state where the drilling is completed and the square pipe W is discharged from the press machine. It is also possible to operate the lid opening device 13 in order to collect the scrap accumulated in the scrap accommodating portion 28 of the inner mold device 4 at the stage where the square pipe W finishes a predetermined number of holes. In this case, the frame 9 is moved by the cylinder 12 so that the inner mold device 4 is positioned as shown in FIG. 5, and the square pipe W is inserted into the square pipe W by the positioning drive device 11. What is necessary is just to move to the left end part of FIG.

  In the present embodiment, the expansion / contraction mechanism of the <4> inner mold apparatus and the <5> scrap recovery mechanism have been described in the form using the pilot mold, but the <4> inner mold apparatus in the form not using the pilot mold. A mold apparatus and a drilling apparatus may be used that use the expansion / contraction mechanism and <5> scrap recovery mechanism.
