开式压机工作时,机身会产生垂直变形和角变形,这将影响冲压件的精度,降低模具寿命,加速滑块导向部分的磨损。由于机身形状复杂,其刚度计算十分困难,通常的设计方法是:首先确定机身的结构尺寸,然后选用较低的许用应力将机身结构作简化处理,用材料力学的方法进行强度计算,最后将机身简化成折杆,对刚度作近似估算。但
Open press work, the fuselage will produce vertical deformation and angle deformation, which will affect the accuracy of stamping parts, reduce mold life, accelerate the slider-oriented part of the wear and tear. Due to the complex shape of the fuselage, the stiffness calculation is very difficult, the usual design method is: first determine the size of the fuselage structure, and then use the lower allowable stress to simplify the fuselage structure, the use of material mechanics method of strength calculation , And finally simplified the fuselage into a folding rod, an approximate estimate of the stiffness. but
