在冲压件生产中,获得较好的技术经济效果,必须按照冲压件的技术要求与批量选择相应的模具,即“按件选模”。本文着重探讨一些与常规冲模不同的冲裁模与成形模,供选择时参考。在板料冲压生产中,除了常规的冲裁模与成形模之外,尚有下列模具可以应用于生产。一、按间隙的不同分类 1.合理大间隙冲裁模。其主要优点可以减少制模工时与材料消耗,并能成倍地提高模具寿命。所谓合理大间隙实质上是“按件定隙”,即在满足冲压件质量要求的前提下,选择能使制模成本较低,模具寿命
In the stamping parts production, access to better technical and economic results, must be in accordance with the technical requirements of stamping parts and batch selection of the corresponding mold, that is, “by-item selection mode.” This article focuses on some of the punches and forming die different from the conventional die, for reference when choosing. In the sheet metal stamping production, in addition to the conventional blanking die and forming die, there are still the following molds can be applied to the production. First, according to the different types of gaps 1. Reasonable gap punching die. Its main advantages can reduce the man-hours and material consumption, and can exponentially increase die life. The so-called reasonable large gap is essentially “fixed by the pieces,” that is, to meet the quality requirements of stamping parts under the premise of choice to make the mold lower cost, mold life
