The roundy and straight steel pipe of choosing is at first handled through surface derusting.
The program of described full-automatic numerical control roll extrusion machine can be provided with the different programming operation sequence according to difform bicycle hub.
Described numerical control automatic gas cutting machine device can be provided with different program operation according to difform bicycle hub.
Described full-automatic numerical control lathe can be provided with different program operation according to difform bicycle hub.
Described full-automatic numerical control extruder can be provided with different program operation through mould again according to difform bicycle hub.
Described the 5th step, on described floral disc, dash 6～20 spoke holes, wherein the diameter of spoke hole is 2.8mm～3.9mm.
Through electroplating, chromium plating is handled again on described made product bicycle hub surface.
Beneficial effect of the present invention: production process is few, has realized the automation of producing, and has improved production efficiency, has practiced thrift production cost, good product quality.
The specific embodiment:
A kind of manufacturing approach of one-body molded bicycle hub, the first step: choose the roundy and straight steel pipe; Second step: the roundy and straight steel pipe through full-automatic numerical control roller press roll-forming, is cut into the needed length of bicycle hub through numerical control automatic gas cutting machine device then; Shape, the 3rd step:, remove a unnecessary slitter edge in skin Steel bowl bearing hole at bicycle hub two ends after the reducing then with the axle skin Steel bowl bearing hole at full-automatic numerical control lathe roll extrusion reducing bicycle hub two ends; The 4th step: roll forming, the bicycle hub of roll extrusion reducing expects to be squeezed into complete integrated bicycle hub pah with the full-automatic numerical control extruder.The 5th the step: with numerical control press on the floral disc of integrated bicycle hub towards spoke hole; At the die two ends of bicycle hub beaming roller is installed then; And on the screw thread of the both sides of beaming roller, install corresponding hex nut, flat shim, locknut, axle shelves and axle bowl, between its axis shelves and the axle bowl dust cap and steel ball are installed; The 6th the step: the 5th the step the basis on, on spoke hole, have chamfering, can obtain the inventive method made the product bicycle hub.The method operation is less, and has realized the mode of production of automation, and the product bicycle hub quality that obtains with this kind method is good, and efficient is high in the time of production, and defect rate is low.
The roundy and straight steel pipe of choosing is at first handled through surface derusting; At first pass through processing of rust removing through the roundy and straight steel pipe, make that the product quality that processes is better.
The program of described full-automatic numerical control roll extrusion machine can be provided with the different programming operation sequence according to difform bicycle hub; Realize the production of automation, improved production efficiency, can be according to the product of client's needs production different model arbitrarily.
