In response to the above-mentioned related technologies, the applicant has proposed a punching equipment with strong adaptability that can not only complete the punching of the same larger steel plate, but also efficiently complete the punching of two smaller steel plates separately, thereby achieving cost reduction and efficiency improvement.

[0023] S4: When the separation guide plate is installed on the limit shovel, two steel plates can be placed on both sides of the limit shovel. The two steel plates can enter the supporting bracket at the same time. The lifting cylinders on both sides assist in positioning. The punching heads on both sides can punch the steel plates on both sides respectively, so that the equipment also has good production efficiency when processing small-format steel plates.
