YB_1系列叶片泵的转子槽磨削是该产品加工的难题之一。积我厂两年的统计资料,仅磨削这道工序报废的转子平均为13%,其中50和100升两种规格的转子报废率竟达20%,这对已经过二十几道工序的零件,是一个很大的损失。对100只因磨槽报废的转子进行检修,发现由于黑皮造成报废的有51只;喇叭口报废13只;出现直槽现象11只;磨糊现象8只;另开槽现象5只;另外还有其他原因报废的12只。下面将以上报废原因作进一步分析,并采取相应的措施改进和提高转子质量。1.黑皮(即槽内壁有“黑色”氧化层)是造成转子报废的主要原因,抓住这个主要
YB_1 series vane pump rotor slot grinding is one of the problems of the product processing. I plot two years of statistical data, only grinding this process scrapped an average of 13% of the rotor, of which 50 and 100 liters of two kinds of specifications of the rotor scrap rate as high as 20%, which has been more than two dozen processes Parts, is a big loss. 100 rotors scrapped due to grinding tank overhaul and found that scrapped due to black skin have 51; trumpet rejection 13; there are 11 straight flute phenomenon; grinding phenomenon of 8; another slot phenomenon 5; the other There are other reasons scrapped 12. The following will scrap the reasons for further analysis, and take appropriate measures to improve and improve the quality of the rotor. 1. Black skin (ie, the inner wall of the tank has a “black” oxide layer) is the main reason for causing the rotor to be scrapped. To grasp this main
