汽车过滤器后支架零件的形状和结构包含冲切、翻边、压印、弯曲和分离等冲压工艺特征。分析其零件结构、生产批量和冲压工艺性,采用级进模可满足零件生产要求。为保证制件的精度和连续冲压过程,设计了与分离工位角度相同的工艺切口,并在对应工位的模具设计了让位槽,确定了以冲孔、冲切、弯曲和整形为主的排样方案;采用导尺配合导正钉定位,设计了内外导向机构和弹性卸料装置进行压料和卸料以保证产品精度;对设计的模具进行了加工、试冲。结果表明,设计的10工位级进模结构合理,成形的产品符合尺寸和精度要求。
Car filter rear bracket parts shape and structure including punching, burring, stamping, bending and separation stamping process characteristics. Analysis of its parts structure, production volume and stamping process, the use of progressive die to meet the production requirements. In order to ensure the accuracy of the workpiece and the continuous stamping process, the same process notch as the separation station was designed, and the allowance slot was designed in the mold corresponding to the station, which was determined mainly by punching, punching, bending and shaping The design of the inner and outer guide mechanism and the elastic unloading device for feeding and unloading to ensure product accuracy; the design of the mold was processed, test-punching. The results show that the design of the 10-position progressive die structure is reasonable, the shape of the product meets the size and accuracy requirements.
