Die burr groove and hydraulic machine forging disc type equipment

Abstract

This invention discloses a die burr groove and a hydraulic press forging device for disc-shaped parts, including an upper die and a lower die. The parting surface between the lower die and the upper die is provided with a burr groove, which has an integrated bridge-bin section. The height of the burr groove is H1, and the width is B = B1 + B2. Based on the characteristics of hydraulic press forging disc-shaped / shaft-shaped parts, this invention uses numerical simulation software to simulate the die forging process, optimizing the traditional "bridge + bin" burr groove into a "bridge-bin integrated" structure. This improves the strength of the burr groove and shortens the processing cycle. A conveying component transports the lower die, containing the part to be forged, into the forging box. Then, through the cooperation of a drive component and an intermittent component, the lower die can be intermittently and automatically moved to the bottom of the hydraulic equipment for forging by the upper die. Finally, the die is discharged outside the forging box. Simultaneously, the drive component can prevent the lower die from getting stuck on the intermittent component by pushing the component, thereby achieving continuous forging and improving forging efficiency.
