一、变形情况影响热处理变形因素是很多的,除热处理本身的原因以外,其他如材料的纤维(流线)方向,模具各处厚薄之差,销孔、螺孔及型孔的形状和分布是否对称,机械加工产生的内应力等,都能引起热处理时的变形,故变形规律是难以捉模的。同样的模具,同样的处理条件,可能产生不同的变形,但大致变形规律如下。 First, the deformation of heat treatment deformation factors are many, in addition to the heat treatment itself, other reasons such as the material fiber (streamline) direction, the difference between the mold thickness, pin hole, screw hole and the shape and distribution of holes is Symmetry, internal stress generated by mechanical processing, etc., can cause deformation when heat treatment, so the deformation laws are difficult to catch the mold. The same mold, the same processing conditions, may have different deformation, but the general rule of deformation is as follows.
