| 中文摘要: |
| 针对某加强框零件的帽形型材弯曲成形加工工艺特点，通过对其成形试验的过程进行总结，提出了采用型材截面畸变控制块改善零件成形方式的全新工艺手段。试验证明，这种成形方法对比热弯、加工中热处理等传统手段更能够有效地解决型材类零件在钣金加工中的截面畸变问题。 |
| 英文摘要: |
| In response to the bending characteristics of the hat-section profile of a strengthening frame a new technology by section distortion control block to improve forming mode is put forward by summery of forming experiments. The experiments show that this technology is more effective to solve the problem of section distortion of profile than conventional techniques of hot bending, heat treatment in processing. |
