我们使用的上海第八机床厂生产的DK6750数控线切割机在断丝后,没有报警装置及自动停机装置,致使断丝后,滚丝筒还不停地转,控制柜也不断驱动工作台继续运行,这不仅会使滚丝电机损坏,而且也行工件的精度受到影响。我们自行设计安装了一个简易装置。使钼丝一断,转丝电机就停车,同时也截断高频电源使工作台不再移动。并采用声光报警,试用后效果较好。现介绍如下:在走丝电机的控制电路中装入一个继电器(JZ),控制电路如附图,导轮Ⅰ搭在丝架与滚丝筒之间,并用导杆与该导轮相联,导
We use the Shanghai Eighth Machine Tool Factory DK6750 CNC wire cutting machine in the broken wire, there is no alarm device and automatic shutdown device, resulting in broken wire, rolling cylinder also kept turning, the control cabinet also continue to drive the workbench to continue Not only does this cause damage to the roller motor, but it also affects the accuracy of the workpiece. We designed and installed a simple device. Make a molybdenum wire off, turn the wire motor to stop, but also cut off the high-frequency power so that the workbench no longer move. And the use of sound and light alarm, good effect after trial. Now introduced as follows: Take the wire in the control circuit of the motor into a relay (JZ), the control circuit as shown in the figure, the guide wheel I ride between the wire frame and roller cylinder, and the guide rod with the guide wheel associated, guide
