Abstract

ABSTRACTFriction at the blank-die contact influences material flow, formability, and product surface quality in processes like deep drawing. Surface modification of the dies by laser texturing is a potential technique to alter the tribological characteristics at the interface during sliding of the sheet over the die surface in lubricated condition. In this work, the effect of laser surface texturing of dies has been investigated under high normal loads during strip drawing of dual phase (DP600) steel. The effect of texture parameters and process parameters on the interface friction between the strip and the dies has been studied. It has been found that the friction coefficient reduced, and the surface finish improved significantly with the textured dies when compared to the conventional die. This study emphasises the importance of surface modification of the dies by laser texturing for its potential application in sheet metal forming processes.KEYWORDS: Laser surface texturingtextured diesstrip drawing testfriction coefficientsurface roughnessdimple sizetexture area density‌lubrication AcknowledgementsArchit Shrivastava would like to acknowledge the assistantship received from the Ministry of Human Resource Development (MHRD), Government of India for this research work.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work is a part of collaborative project between IIT Delhi and Tata Steel R&D, Jamshedpur [Project No: RP03952].

DP600钢板带材拉深中模具激光表面变形

摘要在拉深加工中，坯料与模具接触处的摩擦影响着材料的流动、成形性和产品表面质量。利用激光织构技术对模具进行表面改性是一种有潜力的技术，可以改变在润滑条件下板料在模具表面滑动时界面处的摩擦学特性。本文研究了高法向载荷下双相钢(DP600)带材拉伸过程中激光表面变形对模具的影响。研究了织构参数和工艺参数对带材与模具界面摩擦的影响。实验结果表明，与常规模具相比，织构模具的摩擦系数降低，表面光洁度显著提高。本研究强调了激光变形对模具表面改性的重要性及其在钣金成形工艺中的潜在应用。关键词:激光表面织构、织构膜、带材拉伸试验、摩擦系数、表面粗糙度、凹痕尺寸、织构面积密度、润滑致谢致谢archit Shrivastava感谢印度政府人力资源发展部(MHRD)对其研究工作的资助。披露声明作者未报告潜在的利益冲突。本研究是印度理工学院德里分校和塔塔钢铁研发中心合作项目的一部分[项目编号:r03952]。
