One-piece multi-station hemming mold

Abstract

The invention discloses an integrated multi-station edge folding die, as well as an edge folding method and application thereof, and belongs to the field of die design. The die comprises an upper die, an intermediate die and a lower die, wherein the intermediate die is provided with a female die used together with the upper die, and a movable pressure plate capable of moving up and down is arranged below the intermediate die; the lower die is connected with the intermediate die through a driving cylinder; a V-shaped die head is arranged at a working part at the front end of the upper die; the intermediate die comprises an intermediate die holder and the female die fixed on the intermediate die holder; the female die is provided with a V-shaped groove matched with the V-shaped die head; the pressure plate is movably arranged below the intermediate die holder through a limiting screw; a spring is arranged between the intermediate die holder and the pressure plate. The die can be used for finishing bending of a plate at different angles and finishing bending of a specially-shaped stamping part, particularly machining of a specially Z-shaped workpiece, and is relatively simple in structure, high in bending accuracy and small in spare part number, and molding can be realized at one time without secondary correction. By the method, the specially Z-shaped workpiece can be efficiently machined with high quality.

Description

technical field [0001] The invention belongs to the field of mold design, and more specifically relates to an integrated multi-station hemming mold and a hemming method and application thereof. Background technique [0002] Since the reform and opening up, China's economic development has achieved world-renowned achievements. Its economic strength and comprehensive national strength have been greatly developed in recent decades. The economic strength continues to rise and the economic growth rate continues to accelerate. China The economy has become the focus of attention of countries all over the world. However, in recent years, with the changes in the international environment and the sharp increase in labor costs, Chinese companies are facing a transformation and development process from quantitative changes to qualitative changes. Improvement of product quality, improvement of production efficiency, and reduction of labor costs are all enterprises that break the deadlock...

Problems solved by technology

[0006] The processing of bending dies for existing special workpieces is too targeted, and the use is relatively single. It has no other use except for bending workpieces with specific shapes. If the size of the bending parts changes, the overall size of the mold needs to be changed to meet the processing requirements. Problem, the present invention provides an integrated multi-station hemming die, which is optimized on the basis of traditional bending dies, not only can complete the bending of various angles of the traditional plate, but also can complete the bending of sheet metal parts with specific shapes Processing, especially the processing of the above-mentioned special Z-shaped workpiece, its structure is relatively simple, the bending precision is high, no secondary correction is required for one-time forming, and it can adapt to the processing of bending parts of the same shape and different sizes, and the amount of spare parts is greatly reduced
