The upper end of the frame 1 is connected with two guide rods 12 which are horizontally arranged by using bolts, the two guide rods 12 simultaneously penetrate through the sliding seat 11, and the sliding seat 11 slides along the guide rods 12. The two ends of the screw 23 are fixed to the upper end of the frame 1 by bearing blocks, and the screw is located between the two guide rods 12, passes through the sliding seat 11 and is in threaded connection with the sliding seat 11. The motor 24 (see fig. 1) is a servo motor 24, which is fixed on the upper end of the frame 1 by bolts, and the output shaft of the servo motor is coaxially connected with one end of the screw rod 23 far away from the sawing machine through a coupler. The cylinder body of the air cylinder 22 is fixed on the upper end face of the feeding seat 21 by using a bolt, the axis of the air cylinder is horizontally arranged and is perpendicular to the axis of the lead screw 23, the end face of a piston rod of the air cylinder is connected with a butt joint block 26 by using a bolt, and the butt joint block 26 is abutted against the side wall of a bar. The upper end of the feeding seat 21 is connected with a positioning block 25 through a bolt, and the end face of the positioning block 25 close to the cylinder 22 is abutted to the side wall of the bar. On adding man-hour and arranging the bar in material loading seat 21 to the bar, later cylinder 22 promotes bar and locating piece 25 butt thereby with bar and material loading seat 21's position determination, later lead screw 23 drives the bar and moves one end distance towards the saw bit, utilize the saw bit to cut, the piston rod orientation of cylinder 22 removes the direction of keeping away from the bar after the cutting is accomplished, lead screw 23 drives material loading seat 21 and keeps away from the saw bit and moves, later cylinder 22 presss from both sides the position of bar tightly and continues the pay-off, the material loading process at the bar relies on feed mechanism 2 to accomplish, no longer need the manual work to carry out the material loading to the bar this moment, the while also no longer needs the manual work to detect the displacement distance of bar, the efficiency of bar processing has been promoted.

As shown in fig. 2, when the feeding seat 21 moves in a direction away from the saw blade, friction exists between the bar and the feeding seat 21 to drive the bar to move in the direction away from the saw blade, and the moving distance of the feeding seat 21 is kept constant, which results in the decrease of the moving distance of the bar towards the saw blade, and thus the processed material segment is not satisfactory. Therefore, the position of the lower end of the feeding seat 21 far away from the abutting block 26 is hinged with the upper end of the sliding seat 11, and a gap is left between the lower end surface of the feeding seat 21 and the upper end surface of the sliding seat 11. The sliding seat 11 is connected with a driving mechanism 3 for driving the feeding seat 21 to rotate up and down, and the driving mechanism 3 comprises a guide block 32 fixed at the upper end of the sliding seat 11 and a driving block 31 for pushing the feeding seat 21 to rotate. The guide block 32 is fixed on the upper end surface of the sliding seat 11 by using a bolt, and a guide wedge surface 321 is arranged on the upper end surface of the guide block, and one end of the guide wedge surface 321, which is close to the hinge axis of the feeding seat 21, is inclined downwards. The sliding groove 211 that is on a parallel with the cylinder 22 axis runs through to material loading seat 21 upper end, and the terminal surface under driving block 31 uses the bolt fastening in butt joint piece 26, and the sliding groove 211 and the butt of direction wedge face 321 are passed to driving block 31 lower extreme, and driving block 31 slides along sliding groove 211, and when driving block 31 lower extreme and the butt of guide way upper end, material loading seat 21 upper end personally submits the level setting, and locating piece 25 lateral wall and bar lateral wall butt. When the feeding seat 21 moves towards the direction far away from the saw blade, the piston rod of the air cylinder 22 contracts to enable the driving block 31 to be not abutted to the upper end of the guide block 32 any more, at the moment, the feeding seat 21 rotates downwards to enable the feeding seat 21 and the positioning block 25 not to be in contact with the bar stock any more, the bar stock cannot be moved due to the friction force applied by the feeding seat 21 and the positioning block 25, and the feeding size of the bar stock is more accurate.

As shown in fig. 2, in order that the feeding seat 21 can automatically rotate downward when the driving block 31 contacts the guide wedge-shaped surface 321, the upper end of the sliding seat 11 is connected with two tension springs 27 for driving the feeding seat 21 to move downward, the upper end of each tension spring 27 is hooked on the lower end surface of the feeding seat 21, and the lower end of each tension spring 27 is hooked on the upper end of the sliding seat 11, at this time, when the driving block 31 abuts against the guide wedge-shaped surface 321, the feeding seat 21 rotates downward when downward elastic force is applied to the feeding seat 21 by the tension springs 27, and at this time, the situation that the hinge axis of the feeding seat 21 is blocked and cannot rotate is not easily caused, so that the using process of the feeding mechanism 2 is more stable.

As shown in fig. 2, the driving block 31 continuously rubs against the guide block 32, which may cause the driving block 31 and the guide block 32 to wear and affect the rotation of the loading seat 21. Therefore, the roller 33 is rotatably connected to the lower end of the driving block 31, the lower end of the roller 33 abuts against the guide block 32, and the rotation axis of the roller 33 is parallel to the axis of the lead screw 23. Sliding friction between the driving block 31 and the guide block 32 is converted into rolling friction by the roller 33, abrasion of the driving block 31 and the guide block 32 is reduced, the service life of the driving mechanism 3 is prolonged, and meanwhile, the using process of the feeding mechanism 2 is not easily affected.

As shown in fig. 3, the feeding of the bar stock is affected because the bar stock is pushed by the feeding mechanism 2 toward the saw blade, and friction is generated between the bar stock and the frame 1. Therefore, the upper end of the rack 1 is rotatably connected with a plurality of guide wheels 13, the axes of the guide wheels 13 are perpendicular to the axis of the lead screw 23, the guide wheels 13 are all positioned above the lead screw 23 and are arranged along the axis direction of the lead screw 23, and the bars are placed at the upper end of the guide wheels 13. At this time, the guide wheel 13 is utilized to convert the sliding friction between the bar stock and the rack 1 into rolling friction, so that the friction force between the bar stock and the rack 1 is reduced, and the bar stock feeding process is more convenient.

As shown in FIG. 3, the position of the bar stock on the guide roll cannot be limited at the moment because the guide roll rotates continuously, thereby affecting the feeding and processing of the bar stock. Therefore, one end of each guide wheel 13 inclines towards the direction of the rack 1, a plurality of vertically arranged positioning rods 14 are welded at the upper end of the rack 1, the positioning rods 14 are respectively positioned between the adjacent guide wheels 13, the bar materials are arranged between the positioning rods 14 and the guide wheels 13, and the side walls of the positioning rods 14 are abutted to the bar materials. The position of the bar stock is limited by the guide rollers and the positioning rods 14, so that the bar stock is parallel to the side wall of the positioning block 25 close to the abutting block 26, the position of the bar stock cannot be changed when the bar stock moves towards the saw blade, and the feeding process of the bar stock is more stable.

As shown in FIG. 3, the feeding process of the bar stock is affected because the bar stock continuously generates friction with the positioning rod 14 during the feeding process. Therefore, the positioning rod 14 is sleeved with the positioning wheel 15, the side wall of the positioning wheel 15 is abutted to the bar, and the abutting position of the positioning wheel 15 and the bar is tangent to the end face of the positioning block 25 abutted to the bar. The sliding friction between the bar and the positioning rod 14 is converted into rolling friction by the positioning wheel 15, so that the friction between the bar and the positioning rod 14 is reduced, and the moving process of the bar is more convenient.

As shown in fig. 2, since the abutting block 26 and the bar are made of metal, the friction between the two is small, and at this time, when the bar is positioned by using the abutting block 26, the bar is likely to move relative to the abutting block 26. Therefore, the end face of the abutting block 26 close to the positioning block 25 is adhered with an elastic pad 28, and the elastic pad 28 abuts against the side wall of the bar stock. When butt piece 26 compresses tightly the bar in locating piece 25, thereby the elastic pad 28 produces deformation and has increased the area of contact of elastic pad 28 with the bar, has increased the frictional force between elastic pad 28 and the bar, makes difficult relative movement that produces between bar and locating piece 25 and the butt piece 26, makes the material loading process of bar more convenient.

The implementation principle of the embodiment is as follows: arrange the bar in leading wheel 13 and material loading seat 21 upper end in, the bar is at the guide of the wire wheel that is the slope setting downwards with locating wheel 15 butt this moment, cylinder 22 promotes butt piece 26 and removes towards locating piece 25, driving block 31 removes to the guide block 32 upper end along direction wedge face 321 this moment, material loading seat 21 rotates to the horizontality this moment, butt piece 26 is with bar butt in locating piece 25 terminal surface simultaneously, motor 24 drives lead screw 23 and rotates, thereby drive sliding seat 11 and remove towards the saw bit, utilize the saw bit to cut off the bar. After the bar stock is cut, the piston rod of the air cylinder 22 is contracted, the driving block 31 moves to the guide wedge-shaped surface 321, at this time, the feeding seat 21 is driven by the tension spring 27 to rotate downwards, the motor 24 drives the lead screw 23 to rotate towards the reverse direction, so as to drive the sliding seat 11 to move towards the guide wheel 13, and then subsequent processing is performed.
