Abstract

The invention relates to a three-dimensional curved surface die-pressing forming mold of a thin-wall stamping part and a pressing die method thereof, belonging to the technical field of metal pressing. The three-dimensional curved surface die-pressing forming mold comprises an upper mold, a lower mold and a guide post, wherein the upper mold and the lower mold are arranged oppositely and are respectively connected with the guide post movably; the upper mold comprises an upper die shell and upper die punch heads, wherein a plurality of the upper die punch heads are fixedly and vertically arranged in the upper die shell by a fixed frame in a matrix manner; the lower mold comprises a lower die shell and lower die punch heads, wherein a plurality of the lower die punch heads are fixedly and vertically arranged in the lower die shell by a fixed frame in a matrix manner. The three-dimensional curved surface die-pressing forming mold of the thin-wall stamping part and the press die method thereof are simple, reliable and easy to operate, and can realize metal three-dimensional die-pressing technique with certain strength by convenient and fast combination.

Description

technical field [0001] The invention relates to a device in the technical field of metal pressing and a molding method thereof, in particular to a three-dimensional curved surface molding mold of a thin-walled sheet metal part and a molding method thereof. Background technique [0002] Stamping processing of thin-walled sheet metal parts is an advanced non-cutting processing method, which has many advantages such as low cost, high efficiency, and material saving. , so it is suitable for large-volume stereotyped products, not suitable for personalized or small-batch products. Flexible forming dies can be quickly reconfigured and adjusted according to the shape of parts to be processed to meet the processing requirements of individualized and small batch sheet metal parts, which is of great significance in modern manufacturing technology. The current flexible forming die is composed of multiple punches, each punch is adjusted by a set of motor drive device and fixed by a spec...
