摘要：

针对钣金类零件滚压成形生产线中，经滚压成形的异形横断面零件如何精准且顺利地从被连续滚压成形的料带上剪切下来的技术问题，以图书馆书架中的立柱零件为例，研究了异形横断面零件的结构形状与生产工艺。首创性地引入一种钣金零件异形断面的切断模具，通过对这种钣金类零件自动化生产线中的异形横断面切断模具的凹模结构、凸模结构以及模架结构的设计分析，解决了异形横断面的复杂型材钣金零件在自动化生产线中滚压成形后，顺利从生产线上被切断下来的技术难题；并且在切断时生产线不停机，提高了钣金类零件滚压成形生产线的自动化程度与生产效率，同时也保证了零件的加工质量。

For the technical problem on how to accurately and smoothly cut the roll-formed profiled cross-section part from the continuous rolling stripe in a rolling production line of sheet metal part, taking the column part in the library bookshelf as an example, the structural shape and production process of the profiled cross-section part were studied. Then, the cutting die of the sheet metal part with the profiled cross-section was initially introduced, and the roll forming of complicated sheet metal parts with the profiled cross-section were solved by the design analysis on the die structure, the punch structure and the die frame structure of the profiled cross-section cutting die in the automatic production line of the sheet metal parts. Furthermore, the technical problem of the complicated sheet metal parts with the profiled cross-section cut off from the production line after rolling in the automatic production line was solved, and the production line did not stop when it was cut off. The automation degree and production efficiency of the production line were greatly improved, and the processing quality of parts was improved too.
