More Information
Summary:The head-drawing box for drawing pipe blank includes a box and a main beam inside the box. The main beam is driven by a main cylinder. One blank clamping ring mounted in the slot around one end of the main beam can slide on the inclined plane of one inclined block, and while the main beam shifts it is extruded by the inclined plane to shift radically so as to grip the pipe blank head from the outer wall and transfer drawing force. During production, the pipe blank head needs no pre-treatment before drawing, and this raise the production quality and efficiency.
