我厂有一台T0750型线切割机(桂林无线电专用设备厂产)。原机没有设置断丝保护装置。在加工中如突然断丝,因丝筒马达不能自动断电,丝简继续运转。如果不及时关闭电源,剩余的钼丝将全部混乱。又由于高频未被切断,计算机继续运算,因此数码也被搞乱。这样不仅浪费了钼丝又给工作带来麻烦。我们在丝筒与丝架之间装上一套简易的断丝保护装置。经过长期试用,证实该装置切实可用。此装置与一些电子断丝保护装置相比,有如下特点。
I plant a T0750-type cutting machine (Guilin radio special equipment factory production). The original machine does not set broken wire protection device. In processing, such as a sudden broken wire, because the wire barrel motor can not be automatically cut off, Si Jian continued to operate. If you do not turn off the power in time, the remaining molybdenum wire will be all confusion. And because the high frequency has not been cut off, the computer continues to operate, so the digital has also been confused. This is not only a waste of molybdenum wire and bring trouble to work. We put a simple broken wire protector between the wire cylinder and the wire rack. After a long trial, confirmed that the device is actually available. This device compared with some electronic broken wire protection device, has the following characteristics.
