Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a square wall cover. Background Art

[0002] When punching a square wall cover, a stamping die is used. The square wall cover is placed at a fixed seat arranged on a lower template, and then a hydraulic cylinder drives an upper template and a punching punch arranged on the lower surface of the upper template to move, so as to perform a stamping operation on the surface of the square wall cover.

[0003] After retrieval, a Chinese patent discloses a stamping die (authorization publication number CN218462377U), which includes a lower template, an upper template is arranged on the upper part of the lower template, a hydraulic telescopic column is arranged between the two templates, a fixed seat is arranged on the upper surface of the lower template, a collection hole is opened on the upper surface of the fixed seat, and a punch is arranged on the lower surface of the upper template. Although this patented technology can communicate the bottoms of multiple collection holes through a connecting groove opened inside the fixed seat provided with the collection hole, and a push plate is arranged at the connecting groove. When waste materials enter the connecting hole along with the punch, the push plate can clean the waste materials, avoiding the waste materials from adhering to the bottom of the punch, so as to prevent the waste materials from moving out of the inside of the collection hole along with the punch, so that the punch can be directly used next time.

[0004] However, the above device still has some disadvantages in actual use. The more obvious one is that when the existing stamping die punches a square wall cover, four sets of independent dies and corresponding four sets of equipment are used to process four parts of the square wall cover respectively. This method not only increases the equipment cost, but also occupies a large area, resulting in limited space in the workshop. And the existing punching punches are generally installed on the upper die base through bolts, and some are directly welded to the upper die base. The first one requires special tools for disassembly, increasing the downtime, while the second one makes the punch not easy to replace. Summary of the Utility Model
