Description

Technical Field

[0001] The present invention belongs to the technical field of stamping equipment, and in particular, relates to a stamping equipment for producing motor punching sheets. Background Art

[0002] Motor laminations are usually made of 0.5mm thick silicon steel sheets laminated together and then fixed on the stator and rotor brackets or shafts. They have a wide range of applications.

[0003] When punching and cutting, existing motor punching sheets will produce motor punching sheets and cut fragments. The motor punching sheets and the processed fragments fall together and need to be manually screened, which has low work efficiency. The edges of the motor punching sheets and the processed fragments are often sharp and can easily scratch workers and cause injuries. When the silicon steel sheets are stamped, huge heat will be generated. At the same time, there will be burrs on the surface of the silicon steel sheets. When the silicon steel sheets are stacked for storage and transportation, the burrs will scratch the silicon steel sheets, resulting in reduced quality of the silicon steel sheets, which do not meet the processing standards and reduce the pass rate.
