机器人滚边弱力焊变形的研究

Study on Distortion of Weak Welding with Robot Hemming

摘要: 在介绍弱力焊工艺的基础上，本文主要分析了零件与机器人滚边工艺对弱力焊变形产生的影响，研究了内板上凸点尺寸与位置精度、外板上舌头形状、滚边轨迹、滚边压力、滚边步数对改善弱力焊外观质量所必须的特殊要求，为减小弱力焊变形，优化弱力焊的零件与滚边要求，提升发动机罩的外观质量提供了理论依据。

Abstract: With the introduction of weak welding process, this article mainly analyzes the effects made by parts and robots roller hemming process on weak welding distortion, studies the special re-quirements of bumps dimension and accuracy of position on inner plate, as well as tongue shape, track of roller hemming, pressure of roller hemming, step number of roller hemming on outside plate to improve appearance quality of weak welding, and ultimately provides theoretical basis of decreasing weak welding distortion, optimizing the weak welded parts and roller hemming re-quirements and upgrading the appearance quality of hood.
