          剪板机机床的刚度分析

          2021-03-23 08:38:25点击:

          剪板机机床的刚度指机床在外力作用下反抗变形的能力,机床的刚度越大,动态精度越高;驳母斩劝补辜陨淼母斩群凸辜涞拇ッ斩;补辜陨淼母斩仁滓【鲇诠辜陨淼淖柿闲灾、截面形状、大小等。构件之间的触摸刚度不仅与触摸资料、触摸面的几何尺寸和硬度有关,并且还与触摸面的表面粗糙度、几何精度、加工方法、触摸面介质、预压力等要素有关。

          The stiffness of the plate shearing machine tool refers to the ability of the machine tool to resist deformation under the action of external forces. The greater the stiffness of the machine tool, the higher the dynamic accuracy. The stiffness of machine tool includes the stiffness of machine tool components themselves and the touch stiffness between the components. The stiffness of the machine tool component itself mainly depends on the data nature of the component itself, the shape of the section, size and so on. The touch stiffness between components is not only related to the touch data, the geometric size and hardness of the touch surface, but also related to the surface roughness, geometric accuracy, processing methods, touch surface media, pre-pressure and other factors of the touch surface.
