Problems solved by technology

The welding process not only has many processing procedures, but also has the following disadvantages: 1. The manufacturing process is complicated, especially the requirements for welding technology are high, otherwise it is difficult to ensure better concentricity and affect the dynamic balance of the rim
2. It is necessary to use more expensive gas shielded welding machines and welding processes, which will inevitably increase manufacturing costs
This structure has high requirements on the welding seam. Firstly, it is necessary to ensure that the two halves of the rim disc 11 have good concentricity, and require good sealing performance and high strength of the welding seam. grasp
The rim formed by casting method, although the main body can be an integral structure, but the post-processing process is more complicated

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] see image 3 , the method for spinning edge split forming of a vehicle rim, comprising the steps of:

[0018] A, blanking: preparing a circular plate 6 with a thickness of 8mm, its plate diameter is 300mm;

[0019] B. Edge separation: fix the plate 6 on the rotating shaft 3 of the spinning machine, and use different materials according to the shape and depth of the first wheel 1.1 and the second wheel 1.2 after edge separation, such as from the thickness of the plate At 2 / 3 (the other side 1 / 3), use the spinning wheel of the spinning machine, that is, the tool 4, to carry out spinning and splitting from the outside to the inside in the radial direction, and keep the center of the circular plate as the spoke 2 with a diameter of 17mm, and the thickness of the spoke 2 8mm;

[0020] C, spinning forming: centering on the spoke 2, the spin...

Abstract

The invention provides a method for spinning and edge forming of a vehicle wheel rim, which is characterized in that a circular plate is used, and a spinning machine is used to spin and edge from the outside to the inside along the thickness direction of the plate, and the central circle of the circular plate is retained as spokes. The method of the invention has simple process, does not need complex welding techniques, and also saves expensive gas shielded welding machines; the manufacturing cost can be obviously reduced. Due to the one-time molding technology, the concentricity of the rim can be guaranteed to be completely consistent, thereby ensuring that the dynamic balance of the product is not affected; at the same time, the problem of air leakage caused by the welding seam is completely avoided. Moreover, the rim disk and the wheel spoke formed by this method have the advantages of simple structure, high concentricity, better strength and beautiful appearance.

Description

technical field [0001] The invention relates to a processing technology for manufacturing vehicle rims such as automobiles and motorcycles, and in particular to a spinning and edge-separating method for manufacturing wheel rims from aluminum-magnesium alloy and other metal plates. It belongs to the technical field of mechanical manufacturing. Background technique [0002] Vehicle rims are the basis for mounting and securing tires. Traditional vehicle rims are usually made of aluminum alloy materials by forging or casting, or by spinning. In addition to the casting method that can be formed into an integrated structure at one time, the method of spinning with metal plates is: generally, the half rim disc formed by spinning two aluminum alloy plates is welded. Adopting the welding process to manufacture not only has many processing steps, but also has the following disadvantages: 1. The manufacturing process is complicated, especially the requirements for welding technology ...
