Embodiment 1

[0011] This embodiment is a manufacturing process of a spiral bevel gear, comprising the following steps:

[0012] Blanking → hot forging → cutting flash → punching and continuous skin → annealing → shot peening → phosphating saponification → cold forging → chip processing → heat treatment.

[0013] (1) Cutting.

[0014] (2) Hot forging, preferably at a temperature of 1200°C, using a 1600T friction press to press the material into a tooth-shaped blank.

[0015] (3) Cut flash.

[0016] (4) Chong Lianpi.

[0017] (5) Annealing, heat and keep warm and then cool with the furnace, the cooling rate is less than 25°C / h; after the temperature is less than 450°C, air-cool; the Brinell hardness after annealing is 140-150HB.

[0018] (6) Shot blasting to remove scale.

[0019] (7) Phosphating saponification.

[0020] (8) Cold forging, in order to ensure the precision of the tooth shape, a 2500T hydraulic press is used.

[0021] (9) Chip processing, the specific steps are to drill t...

Abstract

The invention relates to a manufacturing technology of a spiral cone gear. The manufacturing technology comprises following steps of discharging, hot forging, flashing cutting, continuous skin punching, annealing, shot blasting treatment, phosphating and saponification, cold forging, cuttings machining and heat treatment. Compared with traditional machining, the manufacturing technology improves the material utilization rate and greatly reduces the production cost. According to the spiral cone gear subject to extrusion forming, the mechanical property is improved. According to the manufacturing technology, hot forging and cold forging are successively carried out, and the defect existing only through hot forging machining or cold forging machining is overcome.

Description

technical field [0001] The invention relates to a manufacturing process of a spiral bevel gear. Background technique [0002] Spiral bevel gears are important transmission components in rear axles of automobiles, motorcycles and tractors. The traditional manufacturing process is to machine the tooth shape, mainly by using relatively precise machine tools and machining through mechanical cutting. This method has many processing steps, long processing time, low efficiency, high investment in mass production equipment, and cutting processing will cause a large amount of waste of materials and increase production costs. In addition, the cutting process will destroy the integrity of the metal streamline and reduce the mechanical properties of the gear. Contents of the invention [0003] The purpose of the present invention is to provide a kind of spiral bevel gear manufacturing process in order to solve the deficiencies in the prior art, comprising the following steps: [000...
