Bottom surface punching is mainly used to install fixing bolts or other connecting elements to connect the channel steel to other components or equipment. Traditional bottom surface punching of channel steel usually relies on manual operation, and only one punching can be completed at a time. After each punching, the punched channel steel needs to be manually removed and a new channel steel needs to be placed on the punching device for the next punching. This cumbersome operation is not only inefficient, but also increases the workload of the operator and is easily limited by the operator's technical level.

The die frame is fixedly connected to the bracket, and a plurality of hydraulic cylinders are installed on the upper surface. The output ends of the plurality of hydraulic cylinders pass through the die frame and are fixedly connected to the punching head at the end.

[0008] Furthermore, a U-shaped groove is formed between two symmetrically assembled positioning frames, and the positioning frame is threadedly assembled with a locking mechanism, which is composed of a nut, a screw, and a gasket.
