【摘要】 中、小型企业由于设备条件受限(吨位小、数量少),对于批量生产、尺寸较大、工艺流程较长的机架零件,其产量和质量都难以保证,为此,我们研究了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匹配,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。更多还原

【Abstract】 Based on the fact that the limit equipment (low tonnage,small amount) in the medium and small enterprises,the process combination and the methods of reducing cutting forces have been studied and the technology scheme and dies after combination been introduced,according to the quantity and quality problem that were hard to realized in such enterprises,of the frame part that has the big size and long process in serial production.It has realized the most optimization allocation of the hardware system of the enterprise and the technology,improved the processing work efficiency over 30 percent and the die life span over 500 thousand and made the enterprise’s economical benefit dramatically through the process combination and the mould structure improvement.更多还原
