Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Depend on image 3 As can be seen, the wheel spoke processing technology of the present invention is special in that:

[0024] Change the car-made snap ring groove of prior art to press the snap ring slot.

[0025] Specifically, the above-mentioned technical solution may include the following steps:

[0026] S1) Spoke pressing;

[0027] S2) pressing the snap ring groove;

[0028] S3) punching the center hole and flanging.

[0029] In the above technical...

Abstract

The invention provides a vehicle wheel spoke machining technique which is characterized in that a turned clamping spring groove is replaced with a pressed clamping spring groove. Specifically, the technique can comprise the steps of S1) spoke compressing, S2) clamping spring groove pressing and S3) center hole flange punching or the first step and the second step can be conducted at the same time. According to the vehicle wheel spoke machining technique, due to the fact that clamping spring groove pressing is conducted after spoke compressing or clamping spring groove pressing and spoke compressing are conducted at the same time before center hole flanging punching, the process of clamping spring groove turning is omitted, and damage to the internal structure and surface shape of a steel plate material is avoided; furthermore, through clamping spring groove pressing, the density of materials at the position of a clamping spring groove is improved, and as a result, the overall strength of a spoke is effectively improved, and cracking at the position of the clamping spring groove is avoided; meanwhile, the process design enables production efficiency to be improved greatly.

Description

technical field [0001] The invention relates to the field of automobile wheel manufacturing, in particular to a wheel spoke processing technology. Background technique [0002] The spoke is one of the key parts of the wheel. Its outer circle is connected to the rim, and the center hole 2 and the bolt hole 1 are connected to the axle. Each spoke bears a quarter of the load of the passenger car; A stress concentration area is formed around the bolt hole 1, so it is required that the shape in this area is not damaged during the manufacturing process. Whether the manufacturing process is advanced or not is directly related to the strength of this area. [0003] There is a snap ring groove 3 at the flange of the center hole in this area of ​​the spoke (see attached figure 1 ), which is used for clamping the decorative cover. At present, the groove is made by turning the center hole after flanging. The process is: "pressing → punching the center hole flanging → turning the sprin...
