对冲压制件的定位(挡料)方法,进行合理的选择,不仅在冲压模具设计中是重要的方面,而且在模具使用中,也是关系制件尺寸准确度、保证产品质量的重要因素。定位方法的合理选择,要根据制件形状,模具结构和下道工序等情况而定。经多年实践证明,在冲压模具的设计、调整、使用和修理中,我们常采用以下几种比较可靠的定位方法: 1.用螺钉和销钉定位:制件的一边、两边或内孔定位时,首先考虑采用合适的标准件,如 Stamping parts positioning (block) method, a reasonable choice, not only in the stamping die design is an important aspect, but also in the use of molds, is also related to dimensional accuracy of parts, to ensure product quality is an important factor. Positioning method of a reasonable choice, according to the shape of the workpiece, the mold structure and the next procedure and so on. After years of practice proved that in the stamping die design, adjustment, use and repair, we often use the following more reliable positioning method: 1. With screws and pins positioning: Parts of the side, both sides or the hole positioning, First consider the use of suitable standard parts, such as
