company news about What is the forging process of aluminum alloy wheels?

The company has developed an aluminum alloy wheel forging forming process. The process flow can be summarized as follows: (1) heating the billet, heating the aluminum alloy bar to the forgeable temperature, and the preheating temperature of the rotary forging die is 420±10℃; (2) the pier (3) Rotary forging, the pier rough blank is placed on the rotary forging press for rotary forging, and the spokes are formed according to the molding line until the machine is left to increase the amount. The rim part is pre-formed to the size required for spinning; (4) strong hot spinning to complete the hot spinning of the rim. The use of rotary forging presses instead of die forging presses reduces the investment cost of production equipment; after forging, there is no need for trimming and flaring processes, and there is no need to drill and pre-machine before spinning, which shortens the process flow. The production cost is reduced, the production efficiency and the material utilization rate are improved, and this process is especially suitable for the individual market demands of small batches.
