牛头刨床是工厂常用的金加工设备,其电气控制箱较简单,一般用一只LA10-2H按钮和QC12型磁力起动器来控制刨床电动机的运转与停止。但实际使用中操作者在工件进行校调过程中都希望牛头刨还能点动控制。我们是采用如下办法:图1是按钮盒未改动前的常规控制线路接法。图中1~#线亦称电源线,2~#线是自保线,3~#是线圈线。这三根线都是来自电气控制箱。
Shaper is a factory commonly used gold processing equipment, the electrical control box is relatively simple, generally with a LA10-2H button and QC12-type magnetic starter to control the planer motor running and stopped. However, the actual use of the operator in the calibration process of the workpiece all hope that the tamper can move control. We are using the following approach: Figure 1 is the button box is not modified before the conventional control circuit connection. The figure 1 ~ # line also known as the power cord, 2 ~ # line is self-insurance line, 3 ~ # is the coil line. These three lines are from the electrical control box.
