Abstract:The stepping platform is an important part of the traditional electrolytic starting sheet processing unit. Due to the long service life and frequent failures，the operating speed of the machine is seriously restricted， and it is difficult to guarantee the processing quality of the starting sheet，which has been unable to meet the demands of existing production. In view of the above problems，through the in-depth analysis and study of the failure causes，the initial design of stepping platform is optimized from the aspects of structural design and material selection，which reduces the failure rate of this part and improves the operation efficiency of the machine.
