Precision bright press-trimming method for forging burrs

Abstract

A precision bright press-trimming method for forging burrs, which is disclosed by the invention, relates to the technical field of non-cutting metal machining and precision forging. By introducing the steps of pressing and trimming on the basis of conventional process steps and equipment, the method increases the quality of precision-forged products, reduces the production cost, sufficiently exerts the existing equipment conditions of medium and small factories, prolongs the service lives of dies, and saves the expenditure on dies.

Description

technical field [0001] The invention relates to the technical field of metal cold, warm and hot die forging and precision forging, in particular to a precision bright press-cutting method for burrs of forgings. [0002] Background technique [0003] Die forging forming technology in the manufacturing industry, especially metal cold, warm and hot open die forging forming technology is a common technology. Due to the advantages of material saving, energy saving, consumption reduction and emission reduction, it has developed rapidly. [0004] In the metal cold, warm and hot open die forging forming methods, burrs will be generated when the blank is formed. The traditional burrs punching removal method, that is, the punching and shearing method of the convex and concave dies will have an adverse effect on the subsequent processing and the quality of the finished product.

Problems solved by technology

[0004] In the metal cold, warm and hot open die forging forming methods, burrs will be generated when the blank is formed. The traditional burrs punching removal method, that is, the punching and shearing method of the convex and concave dies will have an adverse effect on the subsequent processing and the quality of the finished product. Specifically reflected in: the incision of the traditional burr trimming method is not bright, there are tear bands and strains on the forging, there will be residual burrs and trimming burrs, the quality of the incision is low, and the follow-up processing after trimming is difficult and expensive.
