Problems solved by technology

[0005] However, in this case, the post body is used as the connecting part of the two ends of the prototype rim. The post body needs special tools to screw both sides into the corresponding reserved holes, and the joint of the completed rim will be There is a gap, if it is not treated with reinforcing materials such as glue or anti-rust agent, the rod body in the gap is easily corroded due to moisture and the like, and the corrosion will be serious after a long time break

Embodiment Construction

[0025] The present invention relates to a kind of wheel rim and the manufacturing method of wheel rim, and relevant present invention is to reach above-mentioned object, technical means and effect thereof that feature adopts, please refer to shown in Figure 1, with its corresponding following description:

[0026] The wheel rim of the present invention is made by multiple processing procedures. First, the bending forming procedure: adopt a strip-shaped metal block that has been made out of the mold, put it into the annular groove of a forming mold, and The curvature of the annular groove is pushed by the machine to push the metal block, so that the metal block is bent into a ring-shaped metal rim 1 with a gap 2, and the strip-shaped metal can be aluminum alloy or magnesium alloy.

[0027] The two opposite end faces 3 separated by the gap 2, as shown in Fig. 2 and Fig. 4, are composed of two vertical side edges 10 and a horizontal spacer surface 20 combined to form an H-shaped c...

Abstract

The present invention provides a collar rim and its manufacture method. It mainly includes a long-strip metal block, said metal block is placed into a forming mould so as to form a metal collar rim with a notch; then two end portions separated by said notch and their near surfaces are undergone the processes of sandblasting and gumming treatment so as to make two end portions be tightly combined together; finally, a reinforcement film is tightly stuck on the jointed portion of two end portions and its near surface, then a machine tool is utilized to make pressurizing and heating-stereotyping treatment.

Description

technical field [0001] The invention relates to the field of vehicle rims, in particular to a rim and a method for manufacturing the rim. Background technique [0002] As far as I know, the general rim manufacturing process is to put metal raw materials into a long strip-shaped mold, open the mold to take out a long strip of metal with a uniform specification, and then put it into a ring-shaped forming mold to bend it into a rim Finally, the notch of the rim is welded together, and the rough surface of the entire rim and the welded joint are ground to complete the entire rim; [0003] The joint is welded at high temperature, and its strength has been damaged to a certain extent, and welding slag is sometimes produced to adhere to the rim during the welding process, and the completed joint needs to be ground again. In this way, not only the aesthetics of the rim will be greatly reduced, but also the strength of the joint will be affected. As the use time increases, the stren...
