摘要:
钣金制作是金属加工的一种综合性工艺,焊接作为其中重要环节之一,对于成品的质量精度有着不可或缺的影响。然而在此过程由于温度及应力产生的变形,经常导致焊接完的尺寸达不到精度要求,为降低后期修复成本并提高成品合格率,所以辅具设计与优化成了焊接过程重要的部分,但辅具设计并不是简单成品外轮廓的描绘,需要综合考虑到焊接变形量和可操作性,变形量的计算与预测成为其中重要因素,以此得到适当的辅具,进而使成品的相关尺寸均在要求误差范围之内,达到设计标准,进一步提高经济效益。

Abstract:
Sheet metal fabrication is a comprehensive process of metal processing, and sheet metal welding, as one of the important links, has an indispensable impact on the quality accuracy of the finished product. However, due to the deformation caused by temperature and stress in this process, the size of the completed welding often fails to meet the accuracy requirements. In order to reduce the cost of later repair and improve the qualified rate of the finished product, the design and optimization of auxiliary devices have become an important part of the welding process. However, the Angle design of auxiliary devices is not a simple description of the external outline of the finished product, and the size and direction of welding deformation need to be comprehensively considered. The calculation and prediction of deformation has become an important factor, according to which the corresponding auxiliary tools are designed for auxiliary welding, so that the relevant dimensions of the product are within the required error range, meet the requirements of the drawing design, and further improve the economic benefits.
