Automatic machine for upsetting rod-type workpieces in two directions

摘要

The invention relates to the machining of metals by plastic deformation. The upsetting machine forming the subject of the invention is characterised in that it is equipped with guiding members 27 fixed to the frame 1 parallel to the direction of movement of the slide 10, the upsetting assembly 5 being mounted on the guiding members so as to be able to perform a to-and-fro motion along the upsetting axis in conjunction with the control rod 8 of the mechanism 7 for clamping the half-dies, and to be elastically clamped against the slide 10, and with a damping device 13 interacting with the second upsetting punch 4, which acts as a support punch, and pushing it towards the other upsetting punch 3. The invention applies especially to the manufacture of insulator cores. IMAGE
