<p>The present invention relates to a dieless forming machine, which grasps a punch adjustment axis solidly by reducing the diameter of an upper part of the punch adjustment axis inserted into a grasping chuck as the grasping chuck is inserted or withdrawn out of a lower part of a pusher according to the vertical movement of the pusher through the pusher, and the grasping chuck operating as being linked to an actuator by improving a structure of a punch position adjustment part drastically, and releases grasping of the upper part of the punch adjustment axis by extending the diameter. Thus, position adjustment of a forming punch can be performed precisely by preventing the punch adjustment axis or the grasping chuck from running idle when grasping the punch adjustment axis, thus improving reliability and durability.</p> |
