一、冲裁间隙 通常,间隙是以毛坯材料厚度的百分率予以表示,其为单面的数值;也就是说,对于圆孔的间隙是凸、凹模直径之差的1/2。 图1所示的是五种典型的冲裁件类型,并且是凸、凹模所常用的各种不同的间隙值的范例。 通常,软材料的单边间隙值比硬材料的单边间隙值小。如表1所示。 First, the blanking gap Usually, the gap is expressed as a percentage of the thickness of the blank material, which is a single value; that is, the gap for the hole is convex, die diameter difference of 1/2. Figure 1 shows five typical types of blanking elements and is an example of the various clearance values ​​common to male and female dies. Normally, the unilateral clearance of soft material is smaller than the unilateral clearance of hard material. As shown in Table 1.
