【摘要】：为了冲压生产出合格的多孔板零件,通常采用编程简单的矩阵编程法来编制冲压多孔板上孔的加工程序,但在生产中发现这种编程方法存在不能以"急停"位置为起始点继续冲制剩余孔的缺陷。本文论述了采用逐行编制程序的办法并配合相对坐标系可以克服矩阵编程的缺陷。同时,试生产中还存在"废料反跳"的现象,分析结果表明,"废料反跳"的原因是由于工件或废料与凸模底面之间的吸附力大于与凹模孔壁之间的摩擦力;采用将压力机的装模高度适当调小的方法可以防止"废料反跳"现象发生,并进行了生产试验验证。
[Abstract]:In order to produce the qualified perforated plate parts, a simple matrix programming method is usually used to program the machining program of the holes on the punched perforated plates. However, it is found that this programming method has the defect that the "stop" position can not be taken as the starting point to continue punching the remaining holes. This paper discusses the method of programming by line and the relative coordinate system can overcome the defects of matrix programming. At the same time, the phenomenon of "waste rebound" also exists in the trial production. The analysis results show that the reason of "waste rebound" is that the adsorption force between the workpiece or scrap and the bottom surface of the die is greater than the friction force between the workpiece or the scrap and the die hole wall. The phenomenon of "waste rebound" can be prevented by adjusting the height of the press mold properly, and the production test is carried out.
