摘要:

 

 
根据汽车左侧帽架槽的结构特点及实际生产的技术要求进行多工位排样设计,为解决板料在运送过程中的刚度问题,排样设计采用对称双排结构,导正孔位于板料中心两侧,对称排布,保证送料精度,同时采用导正销确定步距。汽车左侧帽架槽多工位级进模采用顺装结构,使得工件与废料自然分离,有利于减少人工成本。同时,由于汽车帽架槽零件精度要求不高,因此,未进行空工位设计,整体上减少了模具的体积,降低了模具生产制造的成本。生产结果表明,汽车左侧帽架槽多工位级进模能满足产品要求。此外,该模具的材料利用率也高达71.09%,节省了材料。

 

 
According to the structural characteristics of left-side headgear groove for automobile and the technical requirements of actual production, the multi-station layout design was carried out. In order to solve the rigidity problem of sheet metal during the transportation process, a symmetric double-row structure was designed in the layout, the guiding holes were located on the both sides of the center of sheet metal, which were symmetrically arranged to ensure the feeding accuracy, and the step was determined by the guiding pin. Then, the multi-station progressive die of the left-side headgear groove for automobile adopted the direct loading structure, and the workpiece and the waste were naturally separated to reduce labor costs. At the same time, the design of empty work station was not conducted because of the low accuracy requirement of headgear groove parts for automobile, the overall volume of die was reduced, and the cost of die manufacturing was reduced. The production results show that the multi-station progressive die of left-side headgear groove for automobile can meet the production requirements. In addition, the material utilization rate of die is up to 71.09% to save materials.
