Description

technical field [0001] The invention relates to a punching machine. Background technique [0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. The washing machine inner drum is one of the main parts of the washing machine. At present, in the production process of the washing machine inner cylinder, after the inner cylinder body of the washing machine inner cylinder is connected with the rear flange, the lower part of the washing machine inner cylinder needs to be punched. However, the existing punching machine for punching the washing machine inner cylinder There are problems of complex structure, high manufacturing cost and low production efficiency, thus urgently need to be solved. Contents of the invention [0003] The object of the present invention is to provide a punching machine to solve the above problems, so as to solve the problems of complex structure, high manufacturing cost and low produ...
