录音机机芯的开门推板外形零件为不规则的多向弯曲件且弯曲精度要求高,零件折弯高度大。折弯变形后,条料在向下一工位送进时,折弯部分受到模具结构的干涉,模具结构设计难度大。在综合考虑零件加工的工艺方案后,确定采用整体式加必要镶件的组合凹模,两件对排10工位级进模生产,设计出有容料槽的加强型卸料板。本文在模具结构上解决了条料折弯后送进的干涉问题,并取得了良好的使用效果。 Tape recorder movement of the open door push plate shape parts for the irregular multi-directional bending and bending of high precision parts bending height. Bending deformation, the strip feed to the next station, the bending part of the interference by the mold structure, mold design difficult. After considering the process plan of the part processing, it is determined to adopt the integral combined die with the necessary insert, and the two pieces are designed to produce the 10-position progressive die, and the reinforced strip plate with the trough is designed. This article in the mold structure to solve the strip after bending the problem of feeding, and achieved good results.
