When the sensor senses the strip steel plate, it sends a command to the pushing cylinder 90 to push the strip steel plate into the receiving frame to complete the punching and cutting process of the strip steel plate. In general, the patent of the present invention has the advantages of simple structure, high degree of automation, and integrated cutting and punching.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the patent of the present invention rather than to limit it. Although the present invention is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the patent of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
