AI Technical Summary

Technical Problem

In the production of existing battery covers, when different shapes of covers need to be processed, different punches need to be replaced, resulting in a large amount of capital consumption and inconvenience.

Method used

A punch press for battery cover production is designed, using a detachable lower mold seat and upper mold assembly. The corresponding mold seat and mold assembly are replaced to adapt to the processing of covers of different shapes. At the same time, it can be replaced separately when the mold seat and mold assembly are damaged.

Benefits of technology

It realizes flexibility and cost savings when processing cover plates in different shapes, reduces the frequency and capital expenditure of replacement punches, and improves production efficiency and convenience.

Abstract

The utility model relates to the technical field of battery cover plate production, in particular to a punching machine for battery cover plate production, which comprises a working table, supporting legs arranged at the bottom end of the working table, a fixing frame fixedly arranged on the top surface of the working table, a lower fixing seat arranged on the top surface of the working table, and a detachable lower die holder arranged above the lower fixing seat. An upper fixing base and a detachable upper die assembly are arranged above the lower die base, a movable plate is arranged below the lower die base, and a second positioning column is fixedly arranged at the top end of the movable plate. Firstly, the corresponding lower die base and the corresponding upper die assembly are replaced according to the shape of a machining cover plate, meanwhile, the lower die base or the upper die assembly can be independently replaced when the lower die base and the upper die assembly are damaged, and then connection between the upper die assembly and the upper fixing base is enhanced through cooperation of the external thread section, the second nut and the second fixing hole. And finally, the lower mold base can be positioned through a second positioning column, the machined part in the lower mold base can be jacked up through the second positioning column during demolding, and demolding is facilitated.
