[0002] Insulating paper punching and shearing is used in many fields, the most common of which is the electrical industry. In the production of transformers, insulating paper is used to isolate conductors with different potentials to prevent short circuits or electric shock accidents. Insulating paper can also be used to make insulating sleeves, insulating partitions, insulating pads and other insulating materials to play a protective and supporting role.

[0003] The operating efficiency of current insulating paper processing punching and shearing equipment is limited. Usually, the hydraulic pressure of the hydraulic cylinder and the air pressure of the air cylinder are used for punching and shearing. Because the hydraulic and air pressure exchange speeds in the cylinder are not effective, the efficiency of the expansion and contraction frequency of the output ends of the hydraulic cylinder and the air cylinder is low, which is not conducive to the efficiency of the insulating paper punching and shearing processing.

To this end, we propose an insulating paper processing punching and shearing device. Utility Model Content
