Problems solved by technology
[0003] At present, most of the wheel bodies are produced by casting. After casting, rough machining, heat treatment and finishing are required to obtain the required wheel body. Since the blank after casting is relatively rough, the rough The cutting amount of processing is relatively large, which not only wastes raw materials and increases production costs, but also relatively low production efficiency; in addition, because the temperature of the blank after rough machining is relatively low, it is necessary to heat the blank from normal temperature to the required temperature during heat treatment. The energy consumption is relatively high, and the time is relatively long, which will also increase the production cost and reduce the production efficiency

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] The wheel production method provided in this embodiment includes the following steps,
[0028] S1: Prepare the material. Cut the steel pipe with a circular cross section to form a blank according to the predetermined length. The specific cutting length needs to be determined according to the wall thickness of the steel pipe and the size and shape of the wheel body. The steel pipe is preferably a seamless steel pipe or a cast pipe, and the inner diameter of the steel pipe is the same as or slightly larger than the inner diameter of the wheel body to be produced. In addition, the volume of the blank is preferably equal to or slightly larger than the volume of the blank obtained in the next step.
[0029] S2: Forging, first heating the blank to 1050°C-1150°C to increase the creep performance of the material, and then putting the blank into...

The invention provides a wheel body production method. The method comprises the following steps of material preparing, forging, heat treatment, finish machining and the like. Blanks are formed by cutting steel pipes, a forging die with a locating column is adopted for carrying out forging forming, compared with a traditional production method adopting casting forming, size precision of the forgedblanks is higher relatively, the material utilization rate is higher relatively, rough machining is not needed, the cost is low relatively, and the production efficiency is higher relatively. According to the method, due to the fact that heat treatment is carried out on the blanks instantly after forging is completed, lingering warmth of the blanks obtained after forging is fully utilized, energyconsumption of heat treatment is effectively reduced, heating time is effectively shortened, the production cost is further reduced, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a production method of metal parts, especially a production method of a wheel body. Background technique [0002] In order to adapt to complex road conditions, some construction machinery such as excavators and bulldozers will choose to use crawler-type walking systems. This type of walking system usually needs to use wheel bodies as supports, such as roller wheels. [0003] At present, most of the wheel bodies are produced by casting. After casting, rough machining, heat treatment and finishing are required to obtain the required wheel body. Since the blank after casting is relatively rough, the rough The cutting amount of processing is relatively large, which not only wastes raw materials and increases production costs, but also relatively low production efficiency; in addition, because the temperature of the blank after rough machining is relatively low, it is necessary to heat the blank from normal temperature to the requir...
