Problems solved by technology
[0006] However, the existing wheel hub forging and wheel hub casting are two different processes. Usually, the cast hub is used as a forged blank after it cools down. In the process of wheel hub forging, it is necessary to heat the blank hub, and there is energy The problem of waste, at the same time, the production efficiency is also low

Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Such as Figures 1 to 4 As shown, the wheel hub casting and forging equipment in this implementation includes a casting top mold assembly 2, a forging top mold assembly 3, and two moving plates arranged oppositely. The casting top mold assembly 2 and the forging top mold assembly 3 are located at The top of the moving plate is connected by a rotating rod 1. Two casting and forging bottom molds are arranged side by side on each moving plate, and an unloader for taking the cast and forged hub out of the casting and forging bottom mold is arranged on the outside of each moving plate. Material mechanism 71,72, casting top mold assembly 2 comprises casting top mold and the casting cylinder that promotes casting top mold to move up and down, and forging top mold assembly 3 includes forging top mold and the forging cylinder that promotes forgi...

The invention discloses a casting forging method of hub casting forging equipment, and is characterized by comprising the following steps: S1,a casting top mold assembly is used for casting the casting forging bottom mold below, and a forging top mold assembly is used for carrying out die forging on the wheel hub below; S2, two moving plates move by a certain distance, the rotating rod rotates by180 degrees, and the cast wheel hub is cooled, and the forged wheel hub is subjected to discharging, and the casting top mold assembly and the forging top mold assembly work; S3, the two moving platesreset, and the forging top mold assembly and the casting top mold assembly work; S4, the two moving plates move by a certain distance, and the rotating rod continues to rotate by 180 degrees, the forging top mold assembly and the casting top mold assembly work; and S5, the two moving plates reset, and the step S1 is repeated; and S6, the steps S2 to S5 are repeated. The invention provides a casting forging method of the hub casting forging equipment, the heat generated after the hub is cast is fully utilized, and the production efficiency of the hub is improved.
Description
technical field [0001] The invention relates to the manufacture of wheel hubs, in particular to a casting and forging method for wheel hub casting and forging equipment. Background technique [0002] At present, the production methods of hub mainly include casting method, forging method, stamping method and spinning method etc. my country's wheel hub manufacturing is still dominated by low-pressure casting. Wheel hub casting is usually formed by injecting molten aluminum into a mold cavity, and then cooling to obtain a finished product. However, the mechanical properties of cast hubs are usually poor. [0003] For example, the Chinese invention patent with the existing publication number CN106670436B discloses "A Wheel Hub Casting Method", the lower cylinder, the upper cylinder and the side mold cylinder move, and the bottom mold, the top mold and the side mold are pressed against each other to form the wheel hub casting cavity. , the casting machine injects aluminum water ...
