Rim with machining allowance on back of spoke

Abstract

The invention belongs to a machining design, in particular to a rim with machining allowance on the back of a spoke. The machining efficiency of the rim is high. The rim with the machining allowance on the back of the spoke is provided with a rim blank, and is characterized in that: the back of the spoke of the rim blank is provided with a spoke hole; and the machining allowance is present at the periphery of the spoke. The periphery of the spoke is only machined in the subsequent machining, and other parts are not completely machined, so that the slight shrinkage of the back of the spoke of the cast blank is not machined, the surface layer with the best quality of the cast blank is maintained, the product performance and the product yield of the rim can be improved, the product quality performance is improved, and the rim has the advantages of simple structure, simple operation, high production efficiency, good quality and the like.

Description

Technical field [0001] The invention belongs to a mechanical processing design, in particular to a rim with high processing efficiency and processing allowance on the back of the spoke. Background technique [0002] With the development of the automobile industry, automobile wheels are also made of aluminum alloy with good heat dissipation effect and high machining accuracy. The aluminum alloy wheel processing process is generally to first cast a blank with a certain machining allowance, and then undergo heat treatment and machining. , The coating process is made into a finished product. At present, the aluminum alloy wheel blanks are generally designed with a 1.5~2mm machining allowance on the back of the rim. The disadvantage is that the subsequent machining volume is large and the casting quality is easy to be casted on the surface. If the layer is processed, there will be slight shrinkage, and then the method of directly removing the window flash without designing the machini...

Problems solved by technology

[0002] With the development of the automobile industry, automobile rims are also made of aluminum alloy with good heat dissipation effect and high processing precision. The processing technology of aluminum alloy wheels is generally to cast blanks first, and leave a certain processing allowance, and then undergo heat treatment and machining , coating process to make finished products, now aluminum alloy wheel blanks are generally designed with a machining allowance of 1.5~2mm on the back of the rim. If the layer is processed, there will be slight shrinkage, and the method of directly removing the window flash without designing the machining allowance is used. The disadvantage is that the window position flash is not easy to remove, and it will produce uneven flash removal, which affects the rim. quality
