摘　　要：针对目前中、小型企业在设备条件受限(设备吨位偏小、数量偏少)前提下批量生产尺寸较大、工艺流程较长的车架零件难以保证产量和质量问题,研究了其工序合并及降低冲裁力的方法,介绍了合并后的工艺方案及模具。通过工艺合并及模具结构改进,实现了工艺与企业硬件系统的最佳配置,使加工工效提高30%以上,模具寿命达到50万次以上,企业经济效益显著。To salve the quantity and quality problems hard to be warranted of tractor＇ s frame parts which ihave big size and a long process in mass production, based on the fact that the equipments are limited with low tonnage, small amnount in the small and medium-sized enterprise,the process combination and the method for reducing cutting forces are studied, then the mould structure improvement, the most optimal allocation of hardware system with the craft are realized, as the result,the processing efficiency is improved over 30 percent and the die life is got to over 500 thousand times.
