Wheel axle manufacturing method

Abstract

The invention discloses a wheel axle manufacturing method. The manufacturing method is implemented by using the following components: a matter with a hole, a rotatable pushing pin and a pressurized roller, wherein the matter with a hole is arranged on a fixing device, and the fixing device is arranged on a rotating device; the rotatable pushing pin passes through the hole of the matter with a hole and fixedly presses the matter with a hole on the fixing device; the pressurized roller presses the matter with a hole downwards, and simultaneously the pressurized roller moves towards the direction of the rotatable pushing pin; and through rotating and driving materials of the matter with a hole to flow, the matter with a hole is thinned, the extra materials left after the matter with a hole is thinned from the original thickness are pushed until encircling the rotatable pushing pin, and then a hollow flanged wheel axle encircling the rotatable pushing pin is formed. The method disclosed by the invention has the advantages that: a hollow wheel axle can be produced through extruding the matter with a hole without using various processing modes and a large number of human operations, therefore, the manpower is saved, and the forming of the wheel axle is more accurate.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of a wheel shaft. Background technique [0002] There are two methods of making traditional pulleys: [0003] A. Manufacturing method of traditional pulley (1) [0004] Such as figure 1 As shown, the manufacturing method of the pulley is to manufacture the hollow wheel shaft and the V-groove of the pulley respectively, and then use the circumferential welding method to weld the hollow wheel shaft and the V-groove body of the pulley. The welded part of the pulley produced by this method is relatively fragile Moreover, the rigidity and strength are insufficient, the quality is not stable enough, and it is easy to be deformed and the welding is not strong. [0005] B. Manufacturing method of traditional pulley (2) [0006] The steps are: [0007] 1. Starting from a piece of material, the material is punched into a flange shape after multiple stampings. [0008] ...

AI Technical Summary

Problems solved by technology

[0011] but check, Figure 2A The disclosed process of manufacturing the hollow wheel shaft through multiple stampings requires 10 processes, and requires a large number of molds and production equipment. Therefore, the quality of the hollow wheel shaft produced is difficult to control, and the efficiency is low and the cost is high.

[0012] Check separately, such as Figure 2B It is revealed that the hollow shaft of the pulley with the traditional manufacturing method of the pulley will have insufficient fillet radius, and the structural strength is relatively low
