过去我厂检修涡轮发电机时,常因进汽叶片磨损而将整个涡轮更换,造成了很大的浪费.1964年初革新了一套制造涡轮叶片的装备.利用这套装备后,每月按更换六个涡轮计算,全年可节约9000多元. 一、叶片的成形和下料涡轮叶片的材质是??68黄铜,用坩埚熔化,在砂型中浇注成类似于图1所示的形状,毛坯在刨床上用样板刀刨削成图1所示的尺寸,然后利用图2所示的下料夹具截成15毫米长的叶片坯料(最近利用此夹具在冲床上冲剪).
In the past, when I repaired a turbogenerator in our factory, it often caused a lot of waste due to the wear and tear of the intake vanes, resulting in a great waste. A set of equipment for making turbine blades was renovated in early 1964. After using this set of equipment, it was replaced monthly Six turbine calculation, saving more than 9,000 yuan throughout the year.A blade forming and cutting Turbine blade material is ?? 68 brass, crucible melting, pouring into a sand shape similar to the shape shown in Figure 1, blank The size shown in Figure 1 was planed on a planer using the prototype knife and then cut into 15 mm long blanks using the blanking fixture shown in Figure 2, which was recently blanked on a punch press.
