邯郸钢铁总厂炼铁厂铸铁机传动链板(两条链带约需300块),由于工作环境恶劣,磨损严重,每年要消耗一万件以上。链板形状如图1所示,其T形槽在B2012龙门刨床上加工,因刨床立刀抬刀装置靠电磁传动,抬刀量只有15～20mm,达不到加工要求。为了解决这一问题,最初用人工搬动杠杆,配合电磁抬刀。后来采取拖板式抬刀装置,虽然能达到加工件的要求,但经常出现断刀,拖板磨损,易造成失控等故障。既费力,效率又低。为此,现将立刀抬刀装置改
Handan Iron and Steel Plant ironworks drive chain plate (two chains about 300), due to poor working conditions, serious wear and tear, each year to consume more than 10,000. Chain plate shape shown in Figure 1, the T-slot in the B2012 planer processing, because of planer knife lift knife device by electromagnetic drive, lift the knife only 15 ~ 20mm, reach the processing requirements. In order to solve this problem, the first manual lever, with the electromagnetic lift knife. Later to take the drag plate lift device, although able to meet the requirements of processing parts, but often broken knife, carriage wear and tear, easy to cause loss of control and other failures. Effortless, inefficient. To this end, the legislation will now lift the knife device
