The position movement limiting part 50 may be moved to a position in the width direction (Y) before bending of the metal work piece M to adjust the separation distance from the bending part 30, which is a metal work piece by the contact part 23 By adjusting the positional movement limit of (M), by changing the degree of bending of the metal workpiece (M), it is possible for the operator to implement a bending process of the metal workpiece (M) desired by the operator.

The position movement limiting part 50 may be fastened by at least one of the first recessed holes 211 of the first rail part 21 and a fastening member to be moved. That is, the position movement on the first rail portion 21 of the position movement limiting portion 50 is implemented by the fastening member, and thus the separation distance between the location movement limiting portion 50 and the bending portion 30 is determined. .

In addition, the position movement limiting unit 50 is provided on a surface opposite to the metal work piece M, and includes a sensor unit (not shown) that detects whether the metal work piece M is in contact, and the position shift part 20 ) Is detected by the sensor unit, when it is determined that the metal workpiece M and the position movement limiting unit 50 are in contact, the position movement in the width direction Y is stopped.

(Y) When the locking bar 2111 contacts the first limit switch 2112 or the second limit switch 2113 in response to the movement, the current supplied to the cylinder is blocked and movement of the contact portion 23 may be restricted. .

Accordingly, the locking bar 2111 positioned in the space between the first limit switch 2112 and the second limit switch 2113 advances or reverses the distance between the first limit switch 2112 and the second limit switch 2113. Can move.

Here, the first limit switch 2112 and the second limit switch 2113 may be configured separately and operated independently.

In the above, the configuration and features of the present invention have been described based on the embodiment according to the present invention, but the present invention is not limited to this, and various modifications or changes can be made within the spirit and scope of the present invention. It is apparent to those skilled in the art, and thus, such changes or modifications are found to be within the scope of the appended claims.
