Rim production method facilitating mass material preparation

Abstract

The rim production method comprises the following steps that an aluminum plate is cut into rectangular aluminum plate units, and turnups are formed at the ends, in the length direction, of the aluminum plate units; the middles of the aluminum plate units are bent towards the sides where the flanges are located, so that the aluminum plate units form a U-shaped structure; the turned-over edges are pressed to be located in the same plane, the opposite end faces are attached, and the aluminum plate units form a barrel through welding and fixing; machining the barrel into a rim barrel-shaped blank with a circular section; a tire mounting groove and a tire mounting surface are machined in a barrel opening in one end of the rim barrel-shaped blank; carrying out deformity shaping on the rim blank processed with the tire mounting groove and the tire mounting surface; and the shaped rim blank is machined into a rim unit or a rim. According to the rim production method facilitating mass material preparation, rim blanks of the same model can be used for rims of different models and sizes, so that the rim blanks can produce more types of rims, and material preparation and production of the rim blanks are facilitated.

Description

technical field [0001] The invention relates to a technical field suitable for processing and producing wheel rims with different offset distances, in particular to a method for producing wheel rims which is convenient for mass material preparation. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft. Also called rim, steel ring, wheel, tire bell. There are many types of hubs according to diameter, width, molding method and material. [0003] Generally, the hub is fixedly connected with the coaxial center of the rim and the spokes. For the rim, the production process is generally to cut out the aluminum plate that meets the size requirements according to the model size of the wheel hub, and then weld the aluminum plate unit after rolling it into a circle. However, since the aluminum plate its...

Problems solved by technology

However, at present, the production of wheel hubs is mass-customized. The current production process cannot achieve the above effects, resulting in a relatively fixed and long production time period for wheel hubs, and relatively high production costs and inventory costs.
