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
The present invention relates to a kind of manufacturing approach, refer to a kind of manufacturing approach of wheel shaft especially.
Background technology
The preparation method that the conventional belt wheel is made has two kinds:
A. the manufacturing approach () of conventional belt wheel
As shown in Figure 1; The manufacturing approach of belt pulley; Be after V groove with hollow wheel shaft and belt pulley completes separately, to utilize the circumference burning-on method that the hollow wheel shaft is combined with welding with the V groove body of belt pulley again, the weld of the belt pulley that this mode is produced is than fragility and rigidity and undercapacity; Quality is stable inadequately, is prone to have distortion and the not firm situation of welding.
B. the manufacturing approach (two) of conventional belt wheel
Step is:
1. begin from a slice material, dash this material through punching press repeatedly and be flange shape.
2. utilize stamping machine to dash this flange and be the hollow wheel shaft.
3. utilize the stamping machine handle that this hollow wheel shaft is carried out extrusion process, and then produce annular outer edge.
4. utilize V groove forming machine roller system to this material extruding, so that outer rim is shaped to V ditch shape.
Only look into, the warp that Fig. 2 A is disclosed is the punching press process of making the hollow wheel shaft repeatedly, needs 10 operations, and is die needed and production equipment is various, so the difficult control of the quality of this hollow wheel shaft of output, and efficient is low and cost is high.
Other looks into, such as Fig. 2 B announcement, the thick not enough situation of meat of radius of corner can appear in the hollow wheel shaft of the belt pulley of the preparation method that conventional belt wheel is made, structural strength is relatively low.
From the preparation method that aforesaid two kinds of conventional belt wheel is made, can know that the hollow wheel shaft manufacturing process of belt pulley must influence the final mass of belt pulley, in view of this; This case creator thinks to explore through detailed; And accumulate exploitation and the manufacturing experience of being engaged in relevant industries for many years, through constantly studying, testing, satisfy the germinating improvement; Develop a kind of manufacturing approach of wheel shaft, can make the manufacturing of wheel shaft more simple fast.
Summary of the invention
