Casting precision stamping die for sheet metal machining and using method of casting precision stamping die

Abstract

The invention relates to the field of stamping dies, in particular to a casting precision stamping die for sheet metal working and a using method thereof.The casting precision stamping die comprises a lower die device and an upper die device, the lower die device is matched with the upper die device, and the lower die device comprises a female die installation base and further comprises a female die forming assembly installed on the female die installation base; the die comprises a die body, the die body is provided with two sets of female die forming assemblies, the two sets of female die forming assemblies are arranged in a central symmetry mode, each female die forming assembly comprises a first square block, and a first matching groove is formed in the corner of one side of each first square block. And meanwhile, cooling equipment is additionally arranged at the bottom of the concave die, so that the problems that when a traditional sheet metal machining stamping die is used for manufacturing sheet metal parts around an LED lamp shell, precision is low, finished products are inconvenient to take out, and the stamping die is seriously abraded are solved.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a casting precision stamping die for sheet metal processing and a use method thereof. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] LED lamp housing is a kind of led accessories, it is a protective cover to better gather light, make light more concentrated, and reduce the damage of light to eyes. Therefore, LED lamp housing is mostly used in automobile lighting. The role of the LED lamp housing is maximized, and various metal accessories need to be filled around it. In ...

AI Technical Summary

Problems solved by technology

[0006] For this reason, the present invention provides a casting precision stamping die for sheet metal processing and its use method. By filling various support structures in the concave film, the function of supporting the concave film is achieved. At the same time, a cooling device is added at the bottom of the concave film. In order to solve the problems of low precision, inconvenient removal of finished products and serious wear of stamping dies when traditional sheet metal processing stamping dies are used to make sheet metal parts around LED lamp housings
