我厂生产的汽车起动机上用的定子线圈绝缘纸条,原来用剪床加工,废品率占50%左右,工效又很低。后来研制了一台1.5mm以下矩形纸板滚剪机,投入生产使用,工率提高了60倍,废品率由原来的50%下降到万分之五,每年为工厂节约资金5000余元。本机是以2.2kW、1430r/min的三相电机做动力源,通过三角皮带传递到1∶25蜗轮减速器,减速后又经过皮带轮传动主轴,带动从动轮,主、从动刀片一起做相对转动切出相适应的纸板。兹将该机的示意图及刀片零件的工作图介绍如下:
I plant the car starter with stator coil insulation tape, the original use of shearing machine processing, scrap rate of about 50%, ergonomics and low. Later developed a 1.5mm rectangular paperboard roller shear machine, put into production use, work rate increased 60 times, the rejection rate from 50% to ten thousandths of five, annual savings of 5,000 yuan for the factory. The machine is 2.2kW, 1430r / min three-phase motor power source, passed through the V-belt to the 1: 25 worm gear reducer, after deceleration through the pulley drive spindles, driven driven wheel, the main and driven blades together to do relative Turn out the appropriate cardboard. Here’s a schematic diagram of the machine and the working diagram of the blade part as follows:
