在细长类铸件的铸造生产中,当截面壁厚不均匀时,挠曲变形是难以避免的,图 1即为“ T”形梁变形示意图。为控制挠曲变形量。反变形方法已早为人图1T形梁变形示意图们所应用,但如何较准确、简单地确定铸件的反挠曲值并方便于生产,仍是人们所关注的。为此,根据有关的基本理论并结合我厂多年来的生产经验推导出一个比较简易的计算公式,在我厂BQ2010 BQ2010A In the slender casting production, when the cross-sectional wall thickness is not uniform, the deflection is difficult to avoid, Figure 1 is the “T” beam deformation diagram. To control the amount of deflection. The anti-deformation method has long been used for the deformation diagram of the T-shaped beam in Figure 1, but it is still a matter of concern how to determine the anti-deflection value of the casting accurately and simply and to facilitate the production. To this end, based on the basic theory and combined with my factory production experience over the years derived a simple formula, in our plant BQ2010 BQ2010A
