Claims

[Scope of utility model registration request]

A die head for a cutting machine, in which a cutting tool is movably held between a pair of opposing annular plates that are relatively rotatable, and the cutting tool is moved forward and backward in a radial direction in accordance with the relative rotational movement of both plates, A cut-up lever with one end protruding into the center hole of the plate is pivotally attached to one of the plates via a return spring, and is constantly elasticized in the circumferential direction by a spring interposed between the plate and the one plate. A sliding body that is repulsively biased and can be rotatably connected to the other plate is slidably attached thereto, and a swinging lever that is rotatably pivotally connected to the one plate is attached to the sliding body. The lever is engaged and disengaged according to the rotational position of the lever, and the swinging lever and the other end of the cutting-up lever are oscillated by the other end of the cutting-up lever in accordance with the movement of the cutting-up lever. A movable connecting member that is pushed into the lever is interposed, a notch is formed at one end of the movable connecting member to release the cutting lever from rotational operation when the cutting lever is rotated by a predetermined angle or more, and the above-mentioned The swinging lever and the movable coupling member are engaged with each other via an inclined surface formed on at least one of them, so that the swinging lever is rotated about its pivot depending on the relative position of the movable coupling member that is pushed into the swinging lever. When the material to be processed extending in the center hole of the plate comes into contact with one end of the cut-up lever as it rotates gradually and the cut-up lever pivots, the lever pivots and slides via the movable connecting member accordingly. A die head for a cutting machine that is capable of automatically retracting a cutting tool by detaching from a moving body and rotating both plates relative to each other.
