Three Dimensional Finite Element Analysis of Wire Drawing Process

Abstract

This work aims to analytically and numerically study the parameters affecting on the wire drawing process using a 3D finite element model and the effect of these parameters on drawing force. Three-dimensional finite element model using DEFORM-3D V6.1 was built to simulate this process. AL-1100 wire was drawn through a conical die with semi-die angle ( α = 6° , 8° , 8.5° , 9° , 9.5° , 10°,, 15° ), reduction ratio ( r = 0.1 , 0.15 , 0.2 , 0.25 , 0.3), friction coefficient ( µ = 0.1 , 0.08 , 0.075 , 0.07 , 0.065 , 0.06 , 0.05), bearing length ( BL= 0.5 , 0.75 , 1 , 1.25 , 1.6 ) mm, drawing velocity ( 5000, 7500, 10000, 12500, 15000, 17500, 20000)mm/sec. were taken in this study. Many simulations with different parameters were taken to capture the optimum die angle. The results show that the optimum die angle depends on reduction in area (α= 9.5°, 9.5°, 9.5°,10°, 10°) for reduction in area (r= 0.1, 0.15, 0.2, 0.25, 0.3). The drawing force estimated from finite element results was compared with that of analytical results and found in line with maximum error percentage of 4%. The results of finite element model were analyzed statistically using SPSS software in order to find the relationship between the above factors and drawing force.
