天津第一机床厂生产的 YE9050从动锥齿轮淬火压床,是仿制美国格里逊529脉动淬火压床试制的。它主要用汽车后桥从动锥卤轮及其它圆形,平形或圆柱形的齿轮淬火,最大零件直径500毫米。此机床的特点是:1、采用脉冲加压的方法:零件在压模中开始淬火时,压力可瞬间放松再重新压紧,此时油液能强制地围绕齿轮表面流动,因而使其正常地收缩,不致由于压模的接触摩擦而引起内应力,淬火后的齿轮变形可减到最小,得到较好的淬火质量,脉冲次数可以调正,也可以
YE9050 driven bevel gear quenching press produced by Tianjin No.1 Machine Tool Plant is trial-produced by imitation American Glisson 529 pulse quenching press. It is mainly used for automotive rear axle driven cone and other round, flat or cylindrical gear quenching, the largest part diameter of 500 mm. This machine is characterized by: 1, the use of pulse pressure method: part of the quenching began in the mold, the pressure can be relaxed and then re-pressure, then the oil can be forced to flow around the gear surface, so that it normally Shrinkage, not due to the contact pressure of the die caused by the internal stress, gear deformation after quenching can be minimized, get a better quenching quality, the number of pulses can be adjusted, you can
