普通冲模模架(图1)的导向部分是将导套和导往直接压入上下模板的导套孔和导柱孔内的。通常都采用将上下模板叠在一起,在铣床上同时钻铰安装导柱和导套孔的办法,以保证导柱和导套的同心。这在实际加工中,往往存在一些问题; 一、由于立铣头的垂直度问题,造成在上下模板上钻铰出来的孔倾斜。 The leading part of a common die formwork (Figure 1) is to guide the guide sleeve and the guide directly into the guide hole and guide post hole of the upper and lower template. Usually the upper and lower templates are used to stack together in the milling machine at the same time drilling hinge installation guide column and guide hole approach to ensure that the guide column and guide sleeve concentric. This in the actual processing, there are often some problems; First, due to the vertical milling head problem, resulting in the upper and lower template drilling hinge out of the hole tilt.
