Specifically, the input shaft and the output shaft of the speed reducer 33 are coaxially arranged, and the rotation center axis of the tool table 30 coincides with the tool turning axis J2. Thereby, the forming tools T1 to T3 of the tool table 30 can rotate around the tool turning axis J2.

  As shown in FIG. 1, the wire rod rotation driving mechanism 50 is disposed behind the front wall 11A of the base frame 11 and is configured to be able to rotate the wire rod feeding device 12 around the wire rod feeding axis J1.

  Hereinafter, a specific configuration of the wire rotation driving mechanism 50 will be described. As shown in FIG. 3, a rotating base 51 that supports the wire feeding device 12 is pivotally supported on the base frame 11 so as to be rotatable around the wire feeding axis J1. The rotating base 51 passes through the rear wall 11B of the base frame 11 in the direction of the wire feed axis J1, and is supported rotatably on the front wall 11A and a rear cylinder 52 rotatably supported on the rear wall 11B. A front cylinder 53 disposed opposite to the rear cylinder 52 in the direction of the wire feed axis J1, and the central axes of the rear cylinder 52 and the front cylinder 53 coincide with the wire feed axis J1. . The front end of the rear cylinder 52 is fixed to the rear end wall 55 of the rotation base 51, and the rear end of the front cylinder 53 is fixed to the front end wall 56 of the rotation base 51. The connecting wall 54 is connected to the rear end wall 55 at a position offset from the wire rod feeding axis J1. The wire feeding device 12 is received in a portion surrounded by the front end wall 56, the rear end wall 55, and the connecting wall 54.

  The wire rod feeding device 12 includes a pair of feed rollers 13 and 13 that are rotatably supported by the connecting wall 54 around an axis orthogonal to the wire rod feed shaft J1 and sandwich the wire rod feed shaft J1. . In the state where the rotation base 51 is at the rotational position shown in FIG. 1, the feed rollers 13, 13 are arranged side by side in the vertical direction across the wire feed shaft J1, and the upper feed roller 13 is pivotally supported so as to be freely rotatable. At the same time, the lower feed roller 13 is driven by a roller driving servomotor 60M described later. Then, the wire 90 passing through the inner side of the rear cylinder 52 is sandwiched between the feed rollers 13 and 13, and the upper and lower feed rollers 13 and 13 are rotated symmetrically so that the wire 90 is moved along the wire feed axis J1. It is sent to the inside of the front cylinder 53. The roller drive servomotor 60M can feed the wire 90 to the tool linear drive mechanism 20 side (ie, the front side) or pull it back in the opposite direction (ie, the rear side). ing.

  The feed rollers 13 are driven to rotate by a roller drive mechanism 60. A specific configuration of the roller driving mechanism 60 is as follows. That is, as shown in FIG. 3, the inner shaft 61 is rotatably supported by the bearing inside the rear cylinder 52. Further, the rear end wall 55 is provided with a first relay shaft 62 that rotates about an axis parallel to the wire feeding axis J1, and the connecting wall 54 rotates about an axis orthogonal to the wire feeding axis J1. A second relay shaft 63 is provided. Further, the communication wall 54 is provided with a roller support shaft 64 that can rotate integrally with the lower feed roller 13.

  The inner shaft 61 and the first relay shaft 62 are connected by spur gears 61G1 and 62G1, and the first relay shaft 62 and the second relay shaft 63 are connected by bevel gears 62G2 and 63G2. . Further, the second relay shaft 63 and the roller support shaft 64 are connected by flat gears 63G1 and 64G1.

  A roller driving servomotor 60M, which is a driving source of the roller driving mechanism 60, is attached to the rear surface side of the rear wall 11B, and is fixed to the output rotating shaft of the roller driving servomotor 60M and the rear end portion of the inner shaft 61. Connected to the pulley. Thus, the roller driving mechanism 60 is configured, and when the roller driving servomotor 60M rotates the inner shaft 61, the first relay shaft 62, the second relay shaft 63, and the roller support shaft 64 rotate in conjunction with each other, thereby The feed roller 13 on the side rotates together with an axis orthogonal to the wire feed axis J1.

  Also, a wire rod rotation servomotor 50M, which is a drive source of the wire rod rotation drive mechanism 50, is attached to the rear surface side of the rear wall 11B. The output rotation shaft and the rear cylinder 52 of the wire rod rotation servomotor 50M are attached. A pulley fixed to the rear end of the rear end is connected. Then, the wire rod rotation drive mechanism 50 is constituted by these, and when the wire rod rotation servomotor 50M rotates the rear cylinder 52, the wire rod feeding device 12 rotates together with the rotation base 51, and the wire rod 90 is moved. It is made to rotate around the wire feeding axis J1.

  As shown in FIG. 3, the front cylinder 53 is rotatably supported inside a cylindrical recess 16 formed at the rear end of the quill 14, and the quill 14 is fed by a quill rotation drive mechanism 65. The feed shaft J1 is driven to rotate separately from the front cylinder 53. Specifically, a quill rotation servomotor 65M is attached to the rear surface of the front wall 11A, and the output rotation shaft of the quill rotation servomotor 65M and the rear end portion of the quill 14 are connected.

  This completes the description of the configuration of the wire rod forming machine 10. Next, the forming of the wire 90 by the wire forming machine 10 will be described.

  In order to form the wire rod 90 with the wire rod forming machine 10, first, the forming tools T1 to T3 provided in the tool table 30 and the auxiliary tool 74 are retracted from the forming space R1 in front of the quill 14 to drive the rollers. The feed rollers 13 and 13 are rotationally driven by the servo motor 60M, and a wire 90 of a predetermined length is fed from the tip of the quill 14 to the forming space R1.

  Next, the tool table 30 is rotated about the tool turning axis J2 by the tool turning servo motor 32, and, for example, the forming tool T1 is directed to the quill 14 side. Then, the wire rod feeding device 12 is rotated around the wire rod feeding axis J1 by the wire rod rotating servo motor 50M, and the relative rotational position of the forming tool T1 with respect to the wire rod 90 is adjusted. At this time, when the wire 90 is tightly fitted into the wire feed hole 14A, the twist of the wire 90 can be prevented by rotating the quill 14 in the same direction as the wire feed device 12 by the quill rotation drive mechanism 65. It is.

  Next, the second movable base 41 is linearly moved in the X-axis direction and the Y-axis direction by the tool linear drive mechanism 20, and the tool table 30 is disposed in front of the quill 14. Then, the forming tool T1 is abutted against the wire rod 90 protruding from the quill 14. Then, the wire 90 protruding from the quill 14 is formed by the forming tool T1. Here, since the tool turning servomotor 32, the speed reducer 33, and the tool table 30 are arranged side by side in a direction orthogonal to the wire feed axis J1, the forming region R1 is widened forward in the direction of the wire feed axis J1. Can take.

  Subsequently, for example, when forming the wire 90 with the forming tool T2, first, the forming tool T1 is retracted from the forming region R1, and if necessary, the wire 90 is fed to the forming space R1 by a predetermined length. To do.

  Next, the tool table 30 is rotated about the tool turning axis J2, and the forming tool T2 is directed to the quill 14 side. Here, since the second movable base 41 moves linearly in the tool turning axis J2 direction (Y-axis direction), the tool table 30 can be moved only by slightly shifting the tool table 30 in the tool turning axis J2 direction (Y-axis direction). Interference between the forming tools T1 to T3 and the wire 90 when rotating can be avoided. Moreover, since the tool table 30 has a plate shape parallel to the wire feed axis J1, even if the tool table 30 is rotated about the tool turning axis J2, the tool table 30 is positioned in front of the quill 14 at an arbitrary rotational position. The molding region R1 can be widened forward in the direction of the wire feed axis J1.

  When the forming tool T2 faces the quill 14 side, the wire 90 is rotated around the wire feeding axis J1, and the rotational position of the forming tool T2 with respect to the wire 90 is controlled. At this time, as described above, since the tool turning servomotor 32, the speed reducer 33, and the tool table 30 are arranged side by side in a direction orthogonal to the wire feed axis J1, the wire 90 in the molding region R1 is arranged. Even when the wire rod 90 becomes longer in the direction of the wire rod feeding axis J1, the wire rod 90 can be rotated.

  Next, as in the case of the forming tool T1, the second movable base 41 is moved linearly in the X-axis direction and the Y-axis direction, the forming tool T2 is brought into contact with the wire 90, and the wire 90 is formed. In this way, the wire 90 is formed by appropriately switching the forming tools T1 to T3. Then, when the forming of the wire 90 is completed, the second movable base is retracted in the X-axis direction or the Y-axis direction, the forming tools T1 to T3 are retracted from the forming space R1, and the auxiliary tool attached with the cutting tool as the auxiliary tool 74 The drive mechanism 70 is operated to cause the cutting tool to enter the forming space R <b> 1, and the part of the wire 90 that has been formed is separated from the subsequent wire 90. Thereby, the molded product of the wire 90 is obtained.

  As described above, in the wire rod forming machine 10 of the present embodiment, instead of rotating the forming tools T1 to T3 around the wire feed axis J1 as in the conventional wire rod forming machine, the wire 90 is rotated around the wire feed axis J1. Since it is configured to rotate, the relative rotational position of the forming tools T1 to T3 with respect to the wire 90 can be changed as in the conventional wire forming machine. Here, according to this embodiment, since only the tool rotation drive mechanism 31 for rotating the forming tools T1 to T3 around the tool turning axis J2 is mounted on the second movable base 41, the conventional wire rod is provided. Compared to the molding machine, the periphery of the second movable base 41 can be made compact, and the space for molding the wire 90 can be widened. Moreover, since the loading weight of the 2nd movable base 41 becomes lighter than the conventional wire forming machine, the 2nd movable base 41 can be moved quickly.

  Further, since the wire rod feeding device 12 is rotated around the wire rod feeding axis J1, the wire rod 90 can be rotated when the wire rod 90 is loosely fitted in the wire rod feeding hole 14A. Further, since the quill 14 is rotatable about the wire feeding axis J1, the wire 90 in the wire feeding hole 14A interferes with the inner surface of the wire feeding hole 14A when the wire 90 is rotated. To prevent twisting.

  In the wire rod forming machine 10 of the present embodiment, when the wire rod 90 is fitted to the wire rod feed hole 14A, the wire rod rotation drive mechanism 50 does not rotate the wire rod feeding device 12 and the quill rotation drive mechanism 65 does not rotate. By rotating only the quill 14, the wire 90 can be rotated around the wire feeding axis J1.
