Numerical Simulation and Process Optimization on Hot Forming for CuNi90/10 Sock Welding Tee

  • 摘要: 基于Deform-3D,建立了CuNi90/10承插焊三通成形热力耦合有限元模型,对比分析了冲头形状、推制速度、初始温度、摩擦系数等因素对水平载荷的影响,结果表明,柱状凸面冲头成形质量最好,最优的推制速度为40 mm/s,初始温度950~1 000℃,摩擦系数越小越有利于成形。
    Abstract: Aiming at the prominent problem of low material utilization and low production efficiency in the forming process of CuNi90/10 sock welding tee, a new hot forming technology is presented, and a thermal mechanical FEM model is established based on the software Deform-3D, the effects of punch shape, feeding speed, initial temperature of workpiece and friction coefficient on horizontal load is comparatively analyzed. Results show that the quality of cylindrical convex surface of punch is the best, the optimal feeding speed is 40 mm/s, and the suitable initial temperature is 950℃~1 000℃. Besides, the smaller the friction coefficient is, the better the forming quality.
