Problems solved by technology

At present, the material used for steel wheels is ordinary low-carbon steel, and the highest strength of the applied material is 650MPa. It is difficult to reduce the weight of the wheel while ensuring the load with the existing manufacturing process; and the existing equipment has already improved the strength of the material. It cannot be processed and manufactured, and the weight of the wheel can no longer be reduced

Abstract

The invention provides a production process for manufacturing wheels through martensitic steel, and relates to the technical field of production of steel spoke plate type truck wheels. According to the production process, boron-containing materials are applied to multi-step workpiece products of wheel spokes and rims of the wheels; the material structure is converted by heating and cooling; and finally a martensite structure is formed. The tensile strength of the wheels can be improved from 600 MPa of common products to 1000 MPa or above, and the safety performance of the products can be improved completely; and in the wheel products with the same strength, the thickness can be reduced by about 50%, raw materials are saved, energy consumption in use of the wheels is reduced, and the effects of energy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of production of steel spoke plate truck wheels, in particular to a production process of a martensitic steel wheel, the process includes the production process of welding and interconnecting the rim part and the spoke part, through which the Produce higher strength wheel products. Background technique [0002] The wheel is a load-bearing rotating component between the tire and the axle. It usually consists of two main components, the rim and the spoke. The rim is the part used to install and support the tire on the wheel. The supporting part of the rim connection. [0003] In line with the development requirements of environmental protection, energy saving and emission reduction, wheels are developing towards lightweight: the wheel material of light-duty vehicles is transitioning from steel to aluminum alloy; while the wheels of heavy-duty vehicles are still steel. At present, the material used for steel ...
