Detent blanking die structure

Abstract

The invention relates to a detent blanking die structure. The detent blanking die structure comprises a punching die and a female die, wherein the female die comprises a die sleeve, a shrinkage-rod alloy die is arranged on the inner side of the upper portion of the die sleeve, a forming cavity is formed in the center of the shrinkage-rod alloy die, a scroll is arranged at the bottom of the die sleeve, an upper punching rod is arranged on the head of the punching die, a detent base is arranged on the part, inside the die sleeve, of the scroll, a blanking through hole is formed in the center of the scroll and the center of the detent base, and the upper punching rod is inserted in and penetrates through the blanking through hole; detent units are arranged between the detent base and the shrinkage-rod alloy die, each detent unit comprises a detent and a spring inside the corresponding detent and the die sleeve, and an inclined plane is arranged on the position, close to the shrinkage-rod alloy die, of the head of each detent. After the structure is adopted, the problem that a discharging pipe is used for achieving discharging is solved by the adoption of the detent units, a discharging pipe structure is not used any more, discharging is convenient when ultra-thin tubular parts are machined, manpower and machining time are saved, and production cost of enterprises is reduced.

Description

technical field [0001] The invention relates to a mold structure in the machining and manufacturing industry, in particular to a pawl blanking mold structure. Background technique [0002] In the mechanical processing and manufacturing industry, in the production of deep-drawn bottomed tubular products, the production of ultra-thin-walled tubular parts will be difficult to draw and cannot be withdrawn, especially when the product wall thickness is only 0.3 mm. , if the blanking is realized by using the return pipe, the return pipe is difficult to process, only 0.3 mm thick, and the hardness must reach HRC60-63. After the processing is completed, additional material return operations are required, resulting in increased labor and product factory costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ratchet blanking die structure that can facilitate the ejection of ultra-thin wall-thick tubular parts.
