A metal plate part machining and stamping device

Abstract

The utility model relates to mechanical processing technical field provides a kind of metal plate piece processing stamping device, including stamping rod, this metal plate piece processing stamping device further includes: buffer sleeve, it is externally sleeved in the stamping rod;In the utility model, by setting buffer sleeve, buffer and overload protection piece, buffer sleeve bottom end is rigidly connected with punch through mounting plate, the elastic force of buffer can be evenly transmitted to punch, avoid uneven wear caused by punch local excessive stress, ensure that plate piece force is stable simultaneously, reduce crack, deformation and other processing defects;Main spring in buffer and auxiliary spring synergistic effect, the former is through axial telescopic quick absorption stamping momentary high-frequency impact force, the latter is deformed with conical structure absorption low-frequency steady-state impact force, the rigid collision of punch and plate piece is converted into elastic buffer, substantially reduce the crack, indentation of plate piece due to impact, while reducing the wear rate of punch, prolong the life of vulnerable parts.
