Abstract

The invention provides a manufacturing process of a straight bevel gear. The process includes performing medium frequency induction heating on blanks to 1050 to 1150 DEG C, and holding the temperature for 2 to 4 hours to achieve austenitizing; adding the blanks into 5% to 25% of water-based hardening agent for quenching; removing and putting the blanks into an isothermal furnace at 220 to 300 DEG C to perform isothermy for 2 to 4 hours; removing the blanks to perform air cooling to room temperature; performing flattening by a mechanical press to remove a surface oxide layer; performing pre-forging, and ensuring the blanks remaining in a molding cavity; performing rough forging; cleaning tooth surface and spraying an anti-oxidation lubricating film; and performing precision forging to allow the tooth surface of the straight bevel gear to meet the requirements. Compared with cutting, the process has the advantages that the production efficiency and material utilization are improved significantly, more energy and materials are saved, and the cost is lower; material of a product can be saved by 16% to 20% and above, the energy is saved by 8% to 10%, so that the direct cost of the product can be reduced by 80% and above.

Description

Straight bevel gear manufacturing process
Technical field
The present invention relates to a kind of straight bevel gear manufacturing process, belong to field of mechanical technique.
Background technology
Existing straight bevel gear profile of tooth is not easily shaped, and existing technology exists the shortcoming that speed is slow, efficiency is low, low precision, product strength are low, cost is high.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of straight bevel gear manufacturing process.
Technical scheme of the present invention is: a kind of straight bevel gear manufacturing process,
(1) blank Frequency Induction Heating is to 1050 DEG C ~ 1150 DEG C, is incubated 2 ~ 4 hours, realizes austenitizing; Putting into mass concentration is quench in 5% ~ 25% water based quenching agent; Taking-up puts into 220 ~ 300 oisothermal 2 ~ 4 hours in the constant-temperature oven of C; Take out blank air cooling to room temperature;
(2) punching machine flattens and removes surface oxide layer;
(3) blocking, ensures that blank is at shaping mold cavity;
(4) rough forge is shaped;
(5) clear up the flank of tooth and spray resistance oxidation lubricating film;
(6) precision forging, makes the straight bevel gear flank of tooth reach regulation requirement;
Compared with machining, production efficiency and stock utilization are all significantly increased, energy-saving material-saving, and cost is low.Single products can material-saving more than 16% ~ 20%, and energy-conservation 8% ~ 10%, thus make product direct cost reduce by more than 80%.
Detailed description of the invention
A kind of straight bevel gear manufacturing process,
