Abstract

The invention discloses a forming method of a high-speed wheel spoke plate, which further comprises a shaping die used in a shaping step, and the method comprises the following steps: 1) plate shearing and blanking are carried out, and a product blank is prepared from raw materials; (2) stretching forming is conducted, and a radial plate contour piece is manufactured through the product blank; 3) punching: punching a mounting hole and a middle hole in the radial plate contour piece; (4) flanging is conducted, specifically, the edge of the radial plate contour piece is flanged; 5) shaping; according to the method, the position precision of the middle hole and the chamfer of the product is remarkably improved. Cooperative shaping machining of chamfers, mounting holes, middle holes and turned-over edges is completed in the same working procedure through the shaping die. And through the synchronous shaping process, the runout control precision and the chamfering position degree of the radial plate are remarkably improved. According to the method, the production efficiency is greatly improved, accumulative errors are reduced, and high-quality and high-efficiency production of the high-speed wheel spoke plate is achieved.
