Introduction of aluminum block forged aluminum alloy wheels with outer rim wheel lip for rail cars

Forged Al alloy T6 wheels for light load rail cars customized production is a lightweight forged aluminum alloy wheel, which is composed of an outer wheel lip, an inner wheel rim hump, a rim, an outer wheel rim hump, an inner wheel lip, a wheel spoke, a flange and a weight reduction groove, and is characterized in that: the outer wheel lip , The inner rim hump, the rim, the outer rim hump and the inner wheel lip are connected end to end in turn; one end of the spoke is connected to the flange, and the other end is connected to the inner wheel lip to form the wheel surface; the weight reduction groove is located in the back cavity of the wheel One side and the inside of the outer rim hump. The aluminum alloy wheel structure of the utility model has the advantages that: compared with the modified front wheel, the aluminum alloy wheel structure has the advantages of light weight after molding, excellent performance test, material saving, good environmental protection and superior performance.

Strength of  Forged Al alloy T6 wheels for light load rail cars customized production

The difference between forged aluminum alloy wheels and other wheels and the supporting situation of forged aluminum alloys in the market.

KINGRAIL's unique aluminum wheel hub machining tooling has changed the method of positioning and centering the inner cone surface of the aluminum wheel hub in the first process of the aluminum wheel hub machining process, and adopts the process method of outer circle and end face centering and positioning. The tooling of the positioning block or the fixed claw block makes the machining process of the aluminum wheel hub more reasonable, the positioning and centering are more accurate, the tooling is convenient to manufacture, the positioning accuracy is improved, the qualified rate of the product is greatly improved, and greater economic benefits are produced.

The aluminum wheel manufacturing process and the aluminum wheel product method include the following steps: 1) product design; 2) mold design; 3) mold making; 4) aluminum hot forging; 5) T4 heat treatment; 6) T6 heat treatment; 7) CNC precision Processing; 8) Surface treatment; the process of the method provided by the present invention is simple, and can rapidly form an aluminum wheel blank body of a desired shape through hot forging, and then undergo T4 and T6 heat treatment to effectively improve the mechanical properties of the material and eliminate residual stress. And improve the machinability of the metal, to ensure that the product is more compact than the previous aluminum rod structure, without defects such as pores and looseness. Compared with the casting sand casting process, the high-precision hot forging forming process makes the product wear resistance and withstand strength. Enhanced, good comprehensive performance, and the surface is also treated with hard anodizing, the hardness can reach HRC60 ~ 63, effectively prolong the service life, improve the mechanical work efficiency, and is conducive to widespread promotion
