“…It can be seen that the increase in the drawing velocity leads to considerable decrease in the value of the drawing force due to the increase in yield strength and the ultimate tensile strength for the material. These results agree with the results of Kabayama et al [3] and Gawali et al [5] .…”

“…It was found that increasing the bearing length will increase the drawing force and the minimum drawing force was observed when the value of α is optimum, as shown in Figure (7-b). These results agree with the results of Kabayama et al [3]. Figure (7-c) shows the effect of the bearing length on drawing force at constant of semi-die angle α=10˚ and change the values of the drawing ratio (0.1, 0.2 and 0.3).…”

“…SM forward tension curves only are similar to experimental and FEM ones for low reductions carried out in dies with low semi-angles and under low friction conditions. Kabayama et al [3] studied the influence of die geometry in determining the surface and mechanical properties of drawn wires, and consequently, their application. Annealed electrolytic copper wire, with 0.5mm original diameter was reduced by 19% in dies with 2α =10˚ and 18˚ and BL=35 and 50%.…”

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.

The Avitzur's limit analysis for the calculation of the drawing force in a wire drawing process is used to study the real behaviour of a carbon steel in an industrial case. The linear hardening assumption, used by Avitzur only for the first step, is extended to the whole process and tested against experimental data. The result shows that the predictions resulting from this extension are in good agreement with the experimental results and are, as rule, conservative.

“…Kaba yama et al [15] list these parameters as being wire prop erties (yield strength, elastic modulus, strain hardening exponent), lubricant (friction coefficient, viscosity), die geom etry (reduction angle, bearing region length, reduc tion area, and material) and process parameters (tempera ture, drawing speed, material surface treatment).…”

Drawn metal wires such as copper cables, alu minium wires and steel wires have found several applica tions which have an impact on the domestic and commer cial economic uses, namely power cables, welding cables, wire ropes, wire meshes, electrode and filler wire, etc. All these applications require the use of good quality wires. However, this is not easily achieved since wire production faces many challenges. The influence of the drawing die on drawability and the need to maintain the required quality characteristics of the wire stand out among these challenges. This paper gives a background to wire draw ing by highlighting the challenges of attaining the re quired drawability and quality characteristics during wire drawing. It was found from the literature that the draw die geometry has the greatest influence on the quality of copper, aluminium and steel wire products.
