解决“精铸件不精”的问题是许多单位十分关切的课题,笔者想通过个人实践进行粗浅地探讨,以抛砖引玉。 一、奇形精铸件变形规律的研究 影响铸件精度的因素很多,其中以变形和表面缺陷影响最甚。各类奇形薄壁精铸件变形往往是尺寸精度不合格的原因之一。 某些简单结构精铸件的变形规律,已为前人的研究工作所证实。本文将从理论和实践上论证,奇形精铸件的变形同样具有规律性。 Solve the “casting is not fine” problem is a lot of units are very concerned about the subject, I would like to discuss through the personal practice of superficial discussion, to initiate. First, the deformation of the odd-shaped precision castings Research castings affect the accuracy of many factors, including deformation and surface defects most affected. All kinds of odd-shaped thin-walled casting deformation is often one of the reasons for the failure of dimensional accuracy. The deformation of some simple structure castings has been confirmed by previous research work. This article will demonstrate from theory and practice, deformation of the odd-shaped castings also have a regularity.
