为了解决一次成形低矩形引伸件(如图1)的切边问题,我们设计了一种引伸——切边模。三年来对不同质的材料(08钢,镀锌钢板,软铝,62黄铜)在0.5～2MM厚度范围内进行了试用,实践证明,只要模具间隙合理、均匀,即可得到满意的零件。现已广泛应用于生产,得到工人同志的好评。 一、模具结构及工作过程 该模具(图2)主要由引伸凸模13,切边凸模3,凹模21,推件板14,顶件器20,卸料板19组成。由于引伸凸模13在工作过程
In order to solve the trimming problems of the once-formed low-rectangular extension (Figure 1), we designed an extension-trimming die. Three years of different quality materials (08 steel, galvanized steel, soft aluminum, 62 brass) in the 0.5 ~ 2MM thickness within the trial, the practice proved that as long as the mold gap is reasonable and uniform, you can get satisfactory parts. Is now widely used in production, workers have been comrades praise. First, the mold structure and working process The mold (Figure 2) is mainly composed of an extension punch 13, trimming punch 3, die 21, the pusher plate 14, the top 20, the discharge plate 19 composition. Due to the extension punch 13 in the course of work
