在曲轴冲床中,圆肖是主要零件之一。由于它所处的工作条件极其不利,既受震力,又受扭力,表面摩擦也厉害,往往因设计或加工不当,即易使它发生扭断、表面咬坏、卡死等现象。一般说来,冲床事故大都由于圆肖扭断所致。因此要想提高圆肖的使用寿命,就必须对它的尺寸和材料选择多加注意。现以25吨冲床的圆肖为例,叙述如下。一、圆肖尺寸的决定圆肖是装在飞轮与曲轴之间的,并能回转一定角度,这个角度在设计时决定。若将圆肖稍转,就能使冲床作连续或间歇动作。为了保证这种作
In the crankshaft punch, the circle is one of the main parts. Because it is extremely unfavorable working conditions, both by the shock, but also by the torque, the surface friction is also fierce, often due to improper design or processing, that is easy to make it happen to break, surface bite, stuck and so on. In general, the punching accident mostly due to Shou Xiao twist. Therefore, in order to improve the service life of the circle, it must pay more attention to its size and material selection. Now 25 tons of punch punch Xiao as an example, described below. First, the determination of the size of the circle Shaw Shaw is installed between the flywheel and the crankshaft, and can rotate a certain angle, this angle in the design decision. If the circle slightly Shaw, you can make punch for continuous or intermittent action. In order to guarantee this kind of work
