Embodiment 1
[0037] Embodiment 1, a kind of wheel hub forging method, see appendix figure 1 , which is mainly divided into several major steps of material preparation, forging, spinning, heat treatment and machining. Based on a 17-inch aluminum alloy wheel hub, the 7A04 aluminum alloy extruded plate with a thickness of 65mm is thermally cut to a size of 350mm ×350mm×65mm square blank;
[0038] The material preparation stage is a continuous production process in this embodiment, a. After the aluminum rod is melted and cast, an aluminum alloy plate of 350mm×65mm is extruded by an extruder; b. The extruded aluminum alloy plate is conveyed online into the preheating The furnace is heated to 440°C, and preheated for 30 minutes; c. One end of the preheated aluminum alloy plate coming out of the furnace is placed on the supporting mechanism, and the hydraulic cutter at the outlet of the furnace directly cuts the preheated aluminum alloy. On-line hot cutting, the cut billet will fall directly to ...
