影响自动压力机送料精度的因素主要有工艺、模具和机床三个方面。我们重点讨论机床因素,而对工艺、模具因素只作粗略讨论。一、工艺与模具因素为了得到高的送料精度,必须使料在每一次送进和冲裁时的状态一致。若送料或冲裁时,料时紧时松或毛刺过大或清洁条件太差,都会导致送料精度降低。 Affect the automatic press feeding accuracy of the main factors of technology, mold and machine tools in three areas. We focus on machine factors, but the process, mold factors only for a rough discussion. First, the process and mold factors In order to get high feeding accuracy, the material must be in the state of each feed and blanking the same. If feeding or blanking, when the material is tight loose or burr is too large or too poor cleaning conditions, will lead to reduced feed accuracy.
