Embodiment Construction

[0023] Embodiment, referring to the accompanying drawings, a method for manufacturing a steel tubeless wheel for automobiles of the present invention comprises the following steps:

[0024] A. A piece of steel plate with a certain thickness is made into an annular blank plate 10 with a circular hole in the middle (such as figure 1 shown);

[0025] There is a through hole in the middle of the annular blank plate 10;

[0026] The size of the annulus of the annular blank plate 10 is calculated according to the weight of the required product;

[0027] The thickness of the steel plate is also determined according to the needs of the product;

[0028] B. Carry out the mold pressing process for the first time: press this annular blank plate 10 into the hat shape blank plate 20 (as figure 2 shown);

[0029] The first mold can have a convex shape in the middle, or a concave shape in the middle; for different mold shapes, different force directions can be used for the annular blank...

Abstract

The invention discloses a manufacturing method of steel tubeless wheels for vehicles, which comprises the following steps: manufacturing a blank plate which is in the shape of a circular ring and is provided with a circular hole in the middle by using a steel plate with certain thickness; then, pressing the blank plate in the shape of the circular ring into a blank plate which is in the shape of a cap and is convex in the middle by using a pressing machine and a first mold; subsequently, pressing the blank plate in the shape of the cap into a blank plate in the shape of a circular spoke by using the pressing machine and a second mold; then, splitting the plate edge of the blank plate in the shape of the circular spoke from a thick end surface into two small thinned blank plates, and forming a blank piece containing the shape of the circular spoke; and finally, pressing the two small blank plates in a rotating mode to form the shape of a cylindrical rim. The method is especially suitable for manufacturing steel tubeless wheels used for cars, microbuses and the like. The method greatly simplifies the production processes, reduces the equipment investment, improves the accuracy of the products, saves the raw materials, and avoids the waste of the resources.

Description

technical field [0001] The invention relates to a vehicle wheel, in particular to a manufacturing method of a steel tubeless wheel for a vehicle. Background technique [0002] Wheels are one of the important parts of a car, and are generally divided into tubeless wheels and tubeless wheels. Tubeless tires have the advantages of good air tightness, good heat dissipation, simple structure, light weight, etc., and have been widely used. Ordinary tubeless steel car wheels are made of two parts, the spokes and the rim, which are then welded together. The rim is generally manufactured by 8-10 processes such as rolling, welding, rolling, and shaping; the spokes are generally manufactured by 6-8 processes such as stretching, reverse stretching, forming, trimming, flanging, and punching. The above process is cumbersome, the amount of equipment input is large, the processing process is not easy to control, and the product precision is low, manufacturing is difficult, and the scrap r...
