中梁型钢折弯工艺及模具设计

Bending Process and Die Design of Center Sill Section Steel

以某型铁路货车中梁型钢使用板材折弯成形进行了研究,对其使用折弯机弯曲成形进行了工艺分析,利用计算公式核算设备弯曲工艺能力,借助Pro/E软件建立了折弯模设计模型,进行成形过程模拟,并利用仿真分析软件进行模具的强度校核。对模具制造后的试验效果进行总结改进,实现了中梁型钢使用板材折弯成形,提高了制件质量。

The bending process of the center sill of railway wagon produced by our company is studied,and the bending process is analyzed by using a bending machine.The bending process capability of the equipment is calculated by using the calculation formula.The bending die design model is established by using Pro/E software,and the forming process is simulated.The strength of the die is checked by using the simulation analysis software.Summarize and improve the test results after die manufacturing,and realize the bending forming of center sill section steel with plates,which improves the product quality.
