To-be-stamped structure, stamping method and product formed through method

Abstract

The invention relates to the field of machining, in particular to a to-be-stamped structure, a stamping method and a product formed through the method. The to-be-stamped structure comprises a body, a to-be-thinned region and containing cavities. The to-be-thinned region is arranged on the body. The containing cavities are formed in the to-be-thinned region. The stamping method includes the steps that a, the to-be-stamped structure is put into a die; b, stamping and die combination are conducted, the to-be-stamped structure is stamped through the die, meanwhile the thickness of the to-be-thinned region is lowered, and redundant materials are pressed into the containing cavities; and c, the product of a partly-thinned structure is formed. The product is formed through the stamping method. The product of the partly-thinned structure can be formed directly through the to-be-stamped structure by means of a stamping process, so that the problems of the high cost, difficult control and the like existing in a metal corrosion treatment process are solved.

Description

Technical field [0001] This application relates to the field of mechanical processing, in particular to a structure to be stamped, a stamping method, and a product formed by the method. Background technique [0002] In the era of large-size smart phones, the use of hardware brackets for shell materials is an inevitable choice. At present, the stent material has two realization processes, die-casting and stamping. Among them, the die-casting method has high material strength and flexible design, which can easily achieve uneven wall thickness, but it is costly and has a long lead time. Stamping stents have low cost and lead time. Short and high strength characteristics, so the more widely used in the industry is the lower cost stamping bracket method. [0003] However, in the related technology, since the stamping method is integral forming of the sheet, it is difficult to design for local thinning. At present, the common method in the industry is only the method of localized metal ...

AI Technical Summary

Problems solved by technology

At present, there are two kinds of realization processes for bracket materials: die-casting and stamping. Among them, the die-casting method has high material strength and flexible design methods, and can easily achieve uneven wall thickness, but the cost is high and the delivery period is long, while the stamping bracket has low cost and delivery period. Short and high strength, so the industry is more widely used in the lower cost stamping bracket

[0003] However, in the related art, since the stamping method is an integral forming of the plate, it is difficult to design local thinning. At present, the only common method in the industry is the local corrosion of metal, which is costly and difficult to control.
