Tradition pumping line process design and planning usually experience with the pumping line Dies load formula to set eye model half-and pass reduction rate, and the pumping line process can not be achieved at every station of the pumping line load, wire stress and die bear feedback and other parameters of the stress, makes it difficult to determine the final result of the planning and design process is correct, but it is difficult to shorten development time in order to increase industrial competitiveness.
  For this reason, this study Design Expert software for experimental design pumping line process parameters and the need to reduce the factor of the number of simulations, and finite element analysis software DEFORM line be drawn out process simulation results, and then enter Design Expert optimum experimental parametric design, and finally to develop their own line of test pumping machine actual experiments. In this study, carbon wire as material, select the pumping speed, eye mode half-width, eye mold bearing length, eye mode reduced rate of process factors, the application of a first-order response surface methodology was evacuated wire forming eye mold temperature and load and process to investigate the relationship between the factor and the actual pumping line experiments confirm the efficiency of pumping line parameter optimization and simulation accuracy of the predicted value.
  The results are as follows: (1)Optimize the efficiency of pumping line parameter results for eye pattern 14 degrees angle, bearing length of 3.25 mm, pass reduction rate of 19.59%, rate of 81.68mm / s, the average forecast results for Rally 712.9 Kg,Die temperature of 52.63℃; (2) this optimized parameters DEFORM simulation, an average pull of 712Kg (0.12%), eye die temperature of 54.2℃ (2.98%);(3) the final optimized the actual parameters of the pumping line test, the result is an average tension of 750Kg (5.2%), eye die temperature of 55.3 ℃ (5.07%). From the above results to experimental design with finite element analysis pumping line design and planning process parameters, accurate and efficient test process and shorten test time cost.
