Claims

[Scope of utility model registration request]

A hollow main shaft having two bending rollers for bending a wire at one end and a cam groove at the other end, and a hollow main shaft rotatably supported at the center of the hollow main shaft and provided at one end corresponding to the bending rollers. a cylindrical member keyed to the other end of the shaft and having a grooved cam on its outer periphery and a cam groove at one end;
a cam follower that is fixed to the main body and engages in a groove of a grooved cam on the outer periphery of the cylindrical member to move the cylindrical member up and down;
a pin that transmits rotational force from a drive source to the cylindrical member and slides to guide the vertical movement of the cylindrical member, and after the wire presser presses the wire, the two bending rollers bend the wire. A rectangular wire bending machine, characterized in that the cam groove of the cylindrical member is connected to the cam groove of the hollow main shaft when the cam groove of the cylindrical member is rotated 90 degrees for processing.
