According to the leading machine 300 of the present embodiment, the clamp unit 360 includes a first block 361A and a second block 361B that can reciprocate substantially parallel to the transfer direction of the wire 210 by the driving cylinder 350, and the first block 361A. And the second block 361B, the insertion portion 364A through which the wire 210 can be inserted in the transfer direction, and the insertion portion 364A, and approach the front die 310 as the distance from the outer periphery of the wire 210 increases. Guide surfaces 365A and 365B inclined in the direction from the position toward the flaw detection device 371, the first drive unit 363A and the second drive unit 363B driven by the adjustment cylinders 362A and 362B, the first drive unit 363A and the second drive unit 363A 1st holding | maintenance provided in the drive part 363B and guided by the guide surfaces 365A and 365B It comprises a timber 368A and a second holding member 368B, a. The first holding member 368A and the second holding member 368B have holding surfaces 369A and 369B that are substantially parallel to the cam surfaces 368A1 and 368B1 that contact the guide surfaces 365A and 365B and the outer peripheral surface of the wire 210.

According to the clamp unit 360, the holding surfaces 369A and 369B are in a state in which the first holding member 368A and the second holding member 368B move to hold the wire 210. Since the pressure applied to the outer periphery of the wire 210 by the movement of the first holding member 368A and the second holding member 368B is dispersed by the holding surfaces 369A and 369B, the wire 210 is not easily deformed.
In addition, the clamp unit 360 moves the wire 210 by moving the piston rod of the driving cylinder 350 forward while the first holding member 368A and the second holding member 368B hold the wire 210. At this time, the pressure applied to the outer periphery of the wire 210 is dispersed by the holding surfaces 369A and 369B, so that the wire 210 is not easily deformed.

Further, the front die 310 is provided between the shot blast 200 and the flaw detection apparatus 371.
For this reason, the front die 310 processes the wire 210 supplied from the shot blast 200 into a predetermined shape and reduces the scratched portion on the surface of the wire 210, thereby preventing malfunction of the flaw detector 371.

The mounting table 340 provided with the driving cylinder 350 mounts the clamp unit 360 and the wire rod measuring device 370.
For this reason, even if the piston rod of the driving cylinder 350 is moved forward, the clamp unit 360 moves while maintaining a predetermined gap with the wire rod measuring device 370 and thus does not interfere with the wire rod measuring device 370. Further, by operating the piston rod of the driving cylinder 350, the wire 210 can be repeatedly transferred and measured.

Further, the adjustment cylinders 362A and 362B are provided on the side surfaces of the guide shaft support portions 367A and 367B, respectively.
For this reason, it is not necessary to provide a region for arranging the adjustment cylinders 362A and 362B on the mounting table 340, so that the mounting table 340 can be small. And the installation area | region of a tip machine can be made small.

The first drive unit 363A and the second drive unit 363B include a pair of first holding members 368A and second holding members 368B guided by the guide surfaces 365A and 365B.
For this reason, since the first holding member 368A and the second holding member 368B can be accommodated in the insertion portion 364A, the length dimension that is substantially parallel to the transfer direction of the wire 210 in the clamp unit 360 can be reduced.

In addition, the clamp unit 360 and the wire measuring device 370 are provided in a state in which the long wire 210 can maintain a straight shape.
For this reason, the clamp unit 360 is provided in a state in which the holding force for holding the wire 210 is difficult to disperse when the wire 210 is transferred, so that the wire 210 is easily transferred.

In addition, the first drive unit 363A and the second drive unit 363B are guided by the guide surfaces 365A and 365B, and are substantially wedge-shaped first held at the same distance from the first drive unit 363A and the second drive unit 363B. A pair of member 368A and second holding member 368B are provided.
Therefore, when the clamp unit 360 moves in a state where the holding surfaces 369A and 369B are in contact with the outer peripheral portion of the wire 210, the first holding member 368A and the second holding member 368B are substantially equally stressed from the wire 210, respectively. Therefore, the wire 210 can be easily transferred.

  The winding roll 500 includes a winding roll main body 510 that supports the wire 210, a winding guide roll 520 that is provided adjacent to the upper side of the winding roll main body 510 and presses the outer periphery of the wire 210, and the winding roll 500. A pair of press rolls 531A and 531B that are provided near the lower portion of the roll body 510 and press the outer periphery of the wire 210, and roll cylinders 540A and 540B that bias the press rolls 531A and 531B toward the outer periphery of the wire 210 It has.

  For this reason, when the rear end portion of the wire rod 210 is transferred from the rear die 400, the outer peripheral portion of the wire rod 210 supported by the winding roll main body 510 is constantly pressed by the pressing rolls 531A and 531B. Even if spring back occurs in 210, it is possible to prevent the rear end portion of the wire 210 from jumping. Therefore, damage to the wire rod 210 can be prevented.

  In addition, this invention is not limited to one Embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

Although the structure provided in the state which is a direction was shown, it is not restricted to this. For example, the first drive unit 363A and the second drive unit 363B may be provided in a state where the longitudinal direction is the vertical direction. In this case, the guide surface 365A is inclined in a direction away from the mounting table 340 from a position close to the mounting table 340 as it goes from the front die 310 to the wire rod measuring device 370. Further, the guide surface 365B is inclined in a direction approaching the mounting table 340 from a position away from the mounting table 340 as it goes from the front die 310 to the wire rod measuring device 370.

  In addition, the first drive unit 363A and the second drive unit 363B are guided by the guide surfaces 365A and 365B, and are substantially wedge-shaped first held at the same distance from the first drive unit 363A and the second drive unit 363B. Although the configuration in which a pair of the member 368A and the second holding member 368B are disposed is shown, the configuration is not limited thereto. For example, the first holding member 368A may be fixed to the guide surface 365A. In this case, the fixed first holding member 368A may hold and transfer the wire 210 together with the second holding member 368B.

  In the above-described embodiment, the guide surfaces 365A and 365B are configured to incline in a direction away from the outer peripheral surface of the wire 210 as they go from the front die 310 of the wire 210 to the wire measuring device 370.
