Stamping device for connecting piece machining

Abstract

The invention relates to the technical field of connecting piece processing, and discloses a stamping device for connecting piece processing, which comprises a placing bed, a battery connecting plate is placed on the placing bed, and a double pressing assembly is mounted on one side above the battery connecting plate. According to the stamping device for machining the connecting piece, the device can stamp the connecting piece of a positive electrode battery and a negative electrode battery, after the downward pressing motor is started, the second downward pressing block and the first downward pressing block can descend but are not synchronous, and therefore the positive electrode shape and the negative electrode shape of the connecting piece can be stamped respectively, and the stamping efficiency is improved. The problem of stress can be avoided by stamping at different times, so that the problem of bending of the stamped connecting plate is avoided, the problem of repeated machining is avoided due to the fact that descending of the second lower pressing die and descending of the first stamping die are not synchronous, time difference exists, but the second lower pressing die and the first stamping die still belong to the same step in the machining process, and the problem of complex operation is also avoided. And the punching efficiency is improved while the plate is prevented from being bent after punching.
