Embodiment 1

[0030] Embodiment 1, when processing front axle as figure 1 As shown, first put the 6-meter-long steel pipe directly into the spinning machine, start the spinning machine, automatically spin forming and cut off according to the required length without scrap. Such as figure 2 As shown, put the cut semi-finished product into the spinning machine again, start the spinning machine, automatically spin and flanging, and automatically flatten, chamfer and deburr. Polish the finished semi-finished product in the second step to make the surface smooth and flat. Such as image 3 As shown, put it into the automatic double-head extrusion machine, and the disposable double-head extrusion flower disc is formed. Such as Figure 5 As shown, put it into the punching machine to stamp the hole of the faceplate at one time, and then electroplate the product. Such as Figure 6 As shown, the two ends of the product are pressed into the steel bowl, and then the butter grease is automatically ...

Embodiment 2

[0031] Embodiment 2, when processing rear axle as figure 1 As shown, first put the 6-meter-long steel pipe directly into the spinning machine, start the spinning machine, automatically spin forming and cut off according to the required length without scrap. Such as figure 2 As shown, put the cut semi-finished product into the spinning machine again, start the spinning machine, automatically spin and flanging, and automatically flatten, chamfer and deburr. Polish the finished semi-finished product in the second step to make the surface smooth and flat. Such as image 3 As shown, put it into the automatic double-head extrusion machine, and the disposable double-head extrusion flower disc is formed. Such as Figure 4 Thread the semi-finished product as shown, such as Figure 5 As shown, put it into the punching machine to stamp the hole of the faceplate at one time, and then electroplate the product. Such as Figure 6 As shown, the two ends of the product are pressed into...

Abstract

The invention relates to a novel process for manufacturing a bicycle axle hub. The process comprises the following steps of: performing automatic spin forming on a steel pipe and cutting the steel pipe according to a required length; putting a half-finished product into a spinning machine again to automatically plain an end, chamfer and deburr; polishing the prepared half-finished product and putting the prepared half-finished product into a two-head extruding machine to extrude and form a face plate; threading (the step is saved for a front wheel spindle); after electroplating, installing steel cups at two ends by pressing; automatically spraying butter or grease; installing steel beads, a small bearing and a main shaft at one end; installing the steel beads and the bearing at the other end; and after pressing dustproof covers into two ends, installing a spacer and screwing a nut. The process has the advantages of effectively overcoming the defects, reducing material loss of finished products, greatly improving the production efficiency of the products, along with simple process.

Description

【Technical field】 [0001] The invention relates to the technical field of a bicycle part manufacturing process, in particular to the technical field of a novel manufacturing process of a bicycle axle skin. 【Background technique】 [0002] Bicycle is an indispensable means of transportation commonly used in people's life, and at present, the shaft skins of the parts of bicycles are generally produced in the middle tube and the face plate respectively, and then riveted. Among them, the middle tube is generally made of round steel first cut according to the required length and then rounded, and then cut by a lathe; the faceplate generally needs to be cut and flattened by a punch, then annealed and softened, and then extruded by a punch, and then trimmed and punched Cut into discs. The complexity of the above process affects the speed of product forming, and at the same time, there is a great waste of materials, and because the processing process is not precise enough, it affects...
