Continuous stamping die and stamping method for mobile phone camera component

Abstract

The invention discloses a continuous stamping die and a stamping method for a mobile phone camera component. The continuous stamping die comprises an upper die set and a lower die set, the upper die set consists of a plurality of extrusion punches for completing a thinning process, the lower die set comprises a lower die plate and a plurality of lower die inserts corresponding to the extrusion punches, an upper plate surface of the lower die plate is horizontal, the lower die inserts include a plurality of thinning inserts and a restrike insert, and each of the thinning inserts and the restrike insert consists of a sunken pre-machining groove with vertical side walls. The stamping method mainly includes a, pre-machining a material by multiple times by cooperation of the thinning inserts and the corresponding extrusion punches; and b, finally machining the material by the restrike insert and the corresponding extrusion punch, and directly machining the material to form a final product with the target side. The continuous die is adopted, the product is finally formed after a plurality of pre-machining steps, and is low in deformation, standard in size and high in quality, a nitrogen spring is small in size, high in elasticity and constant in spring force, sufficient pressing force is guaranteed during shape punching, and accordingly the product is excellent in flatness.

Description

technical field [0001] The invention relates to a punching die and a punching method, in particular to a continuous punching die and a punching method suitable for a mobile phone camera assembly. Background technique [0002] The mobile phone camera component is a kind of appearance part, which is a necessary part of mobile phone products. The general mobile phone camera components are plastic parts, while the high-end products are mostly metal parts. The metal material is generally stainless steel, so metal stamping will be used. 1. Manufacturing process. At present, most of the stamped products manufactured by metal stamping method are stamped in one time. When it comes to high-end products, the small deformation is relatively large for smaller products, which seriously affects the quality of the product. Such as image 3 As shown in , 15 is a schematic cross-sectional structure diagram of a mobile phone camera assembly, which is divided into two parts: one part is the...
