2) heat：Above-mentioned raw materials are inserted in heating furnace and is heated, heated in proper order at twice, at 800-850 DEG C, second heating and temperature control is at 1000-1100 DEG C for first time heating and temperature control；
3) forging shaping, by the deformation amount controlling of above-mentioned blank between 30%~50%, upsetting pull forging stock 3 times repeatedly, the final forging temperature of last time is 800-900 DEG C；
4) cool down：The good blank of above-mentioned forging is naturally cooled into 300-400 DEG C of air cooling of coming out of the stove；
5) detect a flaw：Ultrasonic examination is made on surface after being annealed by above-mentioned operation, and forging performance heat treatment is carried out after removing all forging defects in surface, and the heat treatment process includes heating quenching, continuous quadratic temper.
Simple structure of the present invention, easy to process, intensity are good, high yield rate, long service life.
