Problems solved by technology

However, these processes have the same disadvantages: whether it is the unbalanced quality caused by welding, or the need to remove the "lugs" caused by the anisotropy of the wheel material after spinning, or even the size of the wheel during processing. Deviations can produce dynamic unbalance, such as figure 1 , figure 2 shown
This will inevitably affect the overall balance effect. At the same time, there are still problems with the stability and firmness of the external mass block. Therefore, the car must often carry out wheel dynamic balance testing, which virtually increases the cost of use.

Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] The method for spinning the dynamic balancing wheel of the present embodiment comprises the following steps:

[0029] Step 1: Process n concave structures at the non-tire-covered, non-installation and non-connection parts of the blank material for spinning, where n is a natural number and n≥3; 8 circular through holes are evenly processed on the spokes of blank processing, such as Figure 5 , Figure 6 shown;

[0030] Step 2: Fill the concave structure described in step 1 with dynamic balance weights. The weights can be made of metal materials with a certain density. The distribution of the weights is as follows: Figure 5 shown;

[0031] Step 3: Perform rough spinning;

[0032] Step 4: Perform fine spinning; before spinning, you can also remove part of the material covered by the tire, such as image 3 , Figure 4 , Figure 5 ...

Abstract

The invention discloses a metal spinning method for a dynamic balance wheel. The metal spinning method mainly comprises the following steps of machining a U-shaped structure, filling the U-shaped structure with a dynamic balance weight, rough metal spinning, fine metal spinning and removing an outer lug on the outer edge of the wheel and an inner lug at the position of a positioning center hole of the wheel which is obtained after the fourth step of fine metal spinning is carried out. According to the machining method, the dynamic balance problem of the finished product wheel is solved in the machining process, regulation of dynamic balance is not needed in the later using process, and the use cost of the product is saved. The finished product wheel is integrally formed in a metal spinning manner, welding is not needed, the structural strength is high, and reliability is higher.

Description

technical field [0001] The invention relates to a processing method of a wheel, in particular to a method for considering the dynamic balance of the wheel during the processing. Background technique [0002] In recent years, with the rapid development of the automobile industry and the continuous improvement of the industry's technical level, the maximum speed of the car is getting faster and faster, and the unbalanced centrifugal force of the wheels during high-speed rotation seriously deteriorates the safety performance of the car. The magnitude and direction of the additional force caused by the imbalance will cause the whole vehicle to jump up and down, and there will be vibrations in the vertical direction of the ground, which will affect the ride comfort of the car; at the same time, the imbalance will also cause the steering wheel to swing laterally. Reducing the maneuverability and stability of the car will directly affect driving safety; in the long run, it will eve...
