Description

Technical Field

[0001] The utility model belongs to the technical field of stamping of automobile door lock shells, and particularly relates to a stamping device for automobile door lock shells. Background Technique

[0002] With the continuous development of the automobile industry and the increasing requirements of consumers for the quality and safety performance of automobiles, as an important part of the automobile safety system, the quality and performance of automobile door locks are particularly important. As the external protection structure of the door lock, the automobile door lock shell not only needs to have sufficient strength and durability, but also needs to meet high standards in appearance design and manufacturing process. In this context, stamping technology has become the preferred method for manufacturing automobile door lock shells due to its high efficiency, high precision, good repeatability, etc. At present, for parts such as lock cores, lock heads, lock catches, and lock shells, due to the need for mass production, equipment production is required to achieve mass production, and most of the lock shell processing is formed by stamping with a one-time molding die.

[0003] Chinese Patent with Publication No. CN219483891U discloses a lock shell forming die for a locomotive electric door lock, including a device main body. A base is arranged inside the device main body. An L-shaped support plate is connected to the upper end of the base. A hydraulic cylinder is arranged at the upper end of the L-shaped support plate, and the output end of the hydraulic cylinder penetrates through the upper end of the L-shaped support plate. The output end of the hydraulic cylinder is connected to a pressure plate, and a upper die is connected to the lower end of the pressure plate. The upper surface of the base is connected to a lower die.

[0004] There are still some deficiencies in the above-mentioned stamping forming device in the actual use process. For example, the upper die and the lower die can be disassembled and assembled conveniently by using screws on the basis of positioning, but this method requires tools for disassembly and replacement, which is relatively limited. Moreover, during the stamping forming process of the lower die, material jamming is likely to occur, affecting the processing efficiency of workpieces. Content of the Utility Model
