| 目的 优化低活化钢的 U 形折弯成形工艺。 方法 应用 DEFORM-3D 仿真软件，对不同工艺参数下的 U 形折弯试验进行模拟，探究成形温度、凸模下行速率以及凹模圆角半径等因素对 U 形折弯效果的影响，对折弯工艺进行优化，最后根据优化参数结果进行实验，并将实验现象与模拟结果进行比较。结果 在成形温度为 600 ℃、凹模圆角半径为 20 mm、凸模下行速率为 0.5 mm/s 时， U 形折弯的模拟效果最优，在此工艺参数下进行折弯实验， 得到的 U 形件满足生产需求。 结论 通过优化合适的工艺参数，使用折弯工艺加工 U 形件完全可行。 |
| 英文摘要: |
| To optimize the bending process of U-shaped for low activation steel, the U-shaped bending tests were simulated by DEFORM-3D simulation software under different process parameters, and the effects of forming temperature, speed and fillet on U-shaped bending were explored to optimize the U-shaped bending process. At last, experiments were taken according to the optimization results, and then the experiment results were compared with the simulation results. The simulation of U-shaped bending had the best effect at 600 ℃, 0.5 mm/s and 20 mm. Bending tests were carried out under these process parameters, and the U-shaped parts obtained met the production requirements. Using the bending process to manufacture the U-shaped parts is completely feasible by optimizing the appropriate process parameters. |
