目前,国内汽车、拖拉机、船用机械等行业中的部分齿轮,已广泛采用精密模锻工艺生产。但由于对齿轮的坯料精度要求较高,一般剪切工艺又达不到生产要求。因此不得不采用落后的锯切落料工艺,但生产效率低,材料浪费多,重量误差大. 后来,我们研制了一副圆钢精密剪切模,安装在JA31-160B闭式单点压力机上落料。经使用,证明坯料质量好,技术经济效果显著。
At present, some of the gears in domestic automobiles, tractors, marine machinery and other industries have been widely used for precision die forging production. However, due to the high precision of gear blanks, the general cutting process can not meet the production requirements. So had to use laggard cutting sawing process, but the production efficiency is low, material waste and weight error.Afterward, we developed a round precision cutting die, mounted on the JA31-160B closed single-point press Blanking. After use, it is proved that the quality of the billets is good and the technical and economic effects are remarkable.
