Device for raising alarm about disconnection and wire arch abnormality at middle part of wire cutting machine

Abstract

The invention relates to a device for raising an alarm about the disconnection and wire arch abnormality at the middle part of a wire cutting machine. The device comprises a disconnection alarm circuit, wherein a disconnection / wire arch abnormality alarm device arranged in a cutting chamber comprises a disconnection rod fixing frame and a stainless steel rod; two parallel through-holes and mounting / fixing through-holes are formed on the disconnection rod fixing frame; two stainless steel rods are arranged in the through-holes; and the tail ends of the two stainless steel rods are connected with the disconnection alarm circuit. Accordingly, the invention can solve the problem of the disconnection and wire arch abnormality at the middle part of the wire cutting machine, effectively prevent the guide wheel for cutting the disconnected wire from being damaged and effectively control the disconnection rate of the abnormal wire arch; and the invention has the characteristic of simple structure, reduces the disconnection rate, prolongs the service life of devices and guarantees the normal production capacity.

Description

technical field [0001] The invention relates to an alarm device for broken wires and abnormal wire bows in the middle of a wire slicer, in particular to an alarm device for broken wires and abnormal wire bows in the middle of a HCT wire cutting machine. technical background [0002] When the HCT wire cutting machine is cutting now, because the steel wire forms a large resistance on the guide wheel, the disconnection protection voltage attenuates greatly, resulting in the silicon rod being cut (if the wire is broken between the F position and the M position) ) The attenuated voltage cannot be sensed without immediately alarming and shutting down, causing the guide wheel to be damaged. Since there are many hard points at the head and tail of the F-position and M-position silicon rods, it is easy to cut and produce jumpers and wire bows. If the cross-section of the silicon rod is uneven and the sticky rods are not aligned, it is very easy to cause serious wire jumps at the cro...

Problems solved by technology

[0002] When the HCT wire cutting machine is cutting now, because the steel wire forms a large resistance on the guide wheel, the disconnection protection voltage attenuates greatly, resulting in the silicon rod being cut (if the wire is broken between the F position and the M position) ) The attenuated voltage cannot be sensed without immediately alarming and shutting down, causing the guide wheel to be damaged

Since there are many hard points at the head and tail of the F-position and M-position silicon rods, it is easy to cut and produce jumpers and wire bows.

If the cross-section of the silicon rod is uneven and the sticky rods are not aligned, it is very easy to cause serious wire jumps at the cross-section of the silicon rod, resulting in a very high probability of disconnection in the middle, and the alarm cannot be reported in time after the wire breaks.
