摘要:

 针对一种打印机内部限位板零件,分析了其结构特点和冲压成形工艺难点,设计了冲压成形方案,进行了排样设计和多工位级进模的结构设计。设计了压线、先“山折”后弯曲成形、Z曲成形、压毛边、冲孔和切断等13道冲压工序,保证工件的成形要求和质量。设计了12对内外导柱、导套同时导向的导向装置,并加设凸模导块,提高了导向精度,保证了冲压精度。采用浮升导料销、导正销和导正针的定位方式,提高了多工位级进模的精度;采用卸料板和弹顶销的弹性卸料装置,提高了工件的平整性。经生产实践证明,打印机内部限位板多工位级进模具能够满足生产要求,可为同类零件的模具结构设计提供依据。

 

 For a internal limiting plate part in pinter, its structure characteristics and stamping process difficulty were analysed, and the stamping process scheme was designed. Then the layout and the multi-station progressive die structure were designed. The thirteen stamping processes, such as pressing line, V bending before bending, Z bending, deburring, punching and cutting were designed to ensure the forming requirement and quality of workpiece. The guiding device with twelve pairs of inner and outer guide pillars and bushings was designed for guiding at the same time, and the guide blocks for punch were designed to ensure guiding and stamping accuracies. The locating mode of lifter stock guide pins, guide pins and guide needles was adopted to improve the accuracy of multi-station progressive die. The elastic unloading device of unloading plates and spring-ejecting pins were adopted to improve the flatness of parts. The production result shows that the multi-station progressive die for the internal limiting plate in pinter meets the requirements of production. It provides a basis for the die structure design of similar parts.
