Technical Field

[0001] The utility model relates to the field of punching dies, in particular to a punching bottom die for processing steel auxiliary frames. Background Art

[0002] During the processing of steel auxiliary frames, it is necessary to punch holes on their surface. Depending on the hole position and size, large holes, small holes, and side holes are generally required. The traditional punching process is to first punch the large holes, then remove them and put them on another device to punch the small holes, and then take them off again to punch the side holes. This is not only a cumbersome process, but also takes a long time to punch. In order to improve efficiency, the large holes, small holes, and side holes can be punched on the steel auxiliary frame at one time. This requires a special punching bottom die to ensure the smooth punching. Based on this, the utility model proposes a punching bottom die for steel auxiliary frame processing. Utility Model Content
