圆盘剪分切工艺有限元仿真研究
A Study of Disc Slitting Process Using Finite Element Simulation
摘要
Abstract
Aiming at the sheet metal disc slitting process,a 2D model of the sheet metal disc slitting process is established and the deformation and fracture process of 304 stainless steel sheet is simulated based on the Oyane ductile fracture criterion by using DEFORM-2D finite element analysis software. The influence law of the axial clearance between two disc cutters, disc cutter corner radius,blank holder force and thickness of sheet metal on the slitting surface topography is revealed. The axial clearance between two disc cutters has the most influence on the slitting surface topography,with the increase of the axial clearance,the rollover height increase, and the height of the shear area decreases. Disc cutter corner radius has little influence on the rollover and the shear area,and the most influence on the burr height, with increase of the disc cutter corner radius, the burr height increases. Blank holder force has little influence on the rollover and the shear area,but has most influence on the burr,with the increase of the blank holder force,the height of burr decreases gradually. Thickness of sheet metal has most influence on the height of the shear area,with the increase of the thickness of sheet metal,the height of the shear area increase,has little influence on the rollover and the burr.关键词
