Study on Clinching of Magnesium Alloy Sheets with Different Lower Die Parameters Based on DEFORM 2D
Clinching is a high-speed mechanical fastening technique which is suitable for joining lightweight sheet materials.In order to study the influence of lower die parameters on strength of joint,this paper presents the analysis of the clinching based on DEFORM 2D software.The lightweight,strong and durable,magnesium alloy sheets were carried out to be the joint materials,and the variation of changed process for die depth,groove fillet radius,groove depth,groove width and draft angle were analyzed.By studying the main geometrical parameters of clinched joint,the influence trend in the strength of joint were obtained by the single assessment process.The result indicated that the strength of joint can be effectively improved by suitably controlling the die parameters.
