此模具曾于1976年获得日本金属压力机工业协会优秀奖。加工零件为磷酸盐薄膜防锈钢板槽钢,如图1所示,一次切成45°斜口,切断后不需要修整加工。模具结构如图2所示。图2a是凹模结构,为了修磨调整方便,凹模由5块镶块组成,两侧各有两个止动螺栓,前面有一根导柱,后面有两根导柱,以保持平衡。材料从左方送入,以右侧可调挡铁定位。送料时,材料被下模中托料器抬起,与凹模不接触。凹膜型腔应与槽钢外形完 This mold was awarded the Japan Metal Press Industry Association Excellence Award in 1976. Processing parts for the phosphate film rust-resistant steel channel, shown in Figure 1, cut into a 45 ° inclined mouth, cutting does not require finishing. Mold structure shown in Figure 2. Figure 2a is a die structure, in order to facilitate grinding adjustment, the die consists of five inserts, each side has two stop bolts, in front of a guide post, followed by two guide posts to maintain balance. Material from the left into the right to the adjustable iron positioning. When feeding, the material is lifted by the feeder in the lower die without contact with the die. Concave film cavity should be finished with the channel shape
