Analysis and Parameter Optimization of Extrusion Forming Process of the Front Tube

In order to obtain a good front tube forming effect, the extrusion forming program and processing parameters of the front tube were studied. Using the actual production and processing experience and theory to compare the five kinds of extrusion forming schemes of the front tube, and the optimal solution was worked out; using DEFORM-3D software to simulate the actual machining process and carrying out data processing by orthogonal experiment analysis, the best process parameters were obtained. The results of the analysis show that the fifth scheme is optimal, namely: when pressing, the small end is extruded by 26 mm and the inner hole is extruded at a depth of 7 mm during compound extrusion. The simulation results show that the optimum process parameters are the friction factor of 0.15, the forming speed of 10 mm/s and the hardness of the die of 63 HRC. The optimum process parameters in the process of compound extrusion are the friction coefficient of 0.08, the forming speed of 10 mm/s, Punch the hardness of 63 HRC. This study has certain guiding significance for the actual production and processing of the front tube, and also provides reference for the production and processing of other front tube parts.
