我厂生产的YLR1.1及YYR0.6电机槽楔采用进口耐高温聚脂薄膜,在嵌线中要求成形较好。以前,我厂用一台7.5kW的油压机,并用专用模具加工,但其效率不高,劳动强度大,对此我们进行了多次研究、改进。现改为将一台凸模固定在小台钻床上,通电使其发热,凹模固定在钻床床面上,加工过程仅是简单的上下往复运动,夹具制作非常简单,效率很高.大约3～4s就可加工一件。其结构如图1所示。加工好的零件如图2所示。 I plant YLR1.1 and YYR0.6 motor wedge imports of high temperature polyester film, forming in the law requires better. In the past, I used a 7.5kW hydraulic press in our factory and processed it with special molds, but its efficiency was not high and labor intensity was high. We conducted many research and improvement on this. Now a punch fixed to a small drilling machine, power to heat, die fixed in the drilling bed surface, the process is simple up and down reciprocating motion, the fixture is very simple and efficient. About 3 ~ 4s can be processed one. The structure shown in Figure 1. Processed parts shown in Figure 2.
