Description
(1) technical field
The present invention relates to a kind of filament breakage detection apparatus for steel stranded wire.The detection of fracture of wire takes place when being mainly used in I-beam wheel unwrapping wire in the steel strand wires production process.Belong to the metallic article technical field.
(2) background technology
In the steel strand wires production process, inevitably fracture of wire can take place during the I-beam wheel unwrapping wire in SKIP (Chinese) cabin.If in time do not detect behind the fracture of wire, scattered by the stress effect, the bow that may be wound at a high speed rotation is with and is caused the fracture of bow band, even damage equipment that can be even more serious.Therefore how to solve fracture of wire and detect the speed of production that problem is directly restricting steel strand wires, influence the production cost and the quality of steel strand wires.
At present the most frequently used circuit wire detecting device of steel strand wires production equipment as shown in Figure 1, the centrifugal force that the steel wire broken end relies on the high speed rotation of bow band to produce behind the fracture of wire hits semi arch circuit wire detecting device or copper ring circuit wire detecting device, and equipment alarm is stopped.The fracture of wire detection mode is more passive, therefore in order effectively to detect fracture of wire, should make circuit wire detecting device and bow minimum with the distance that goes up steel wire as far as possible.In actual production process, steel wire can produce certain bending when I-beam wheel is come out through the bow band, crooked steel wire during through the copper ring circuit wire detecting device frequent misconnection touch copper ring and cause the fracture of wire false alarm to stop platform, not only influence product quality, and influence output (at every turn stop platform influence steel strand wires produced about 10 minutes).If suitably transfer the distance between big copper ring and the steel wire, might detect less than fracture of wire behind the real fracture of wire, cause disconnected bow band or bigger damage equipment.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of filament breakage detection apparatus for steel stranded wire that can not produce the fracture of wire false alarm is provided.
The object of the present invention is achieved like this: a kind of filament breakage detection apparatus for steel stranded wire, comprise fabric wheel, support wheel, limit switch, little boat supporting frame, wireless launcher and radio receiver, described fabric wheel is cantilever-shaped and is rotatably connected on the little boat supporting frame, support wheel is fixedly connected on the little boat supporting frame, fabric wheel is pressed on the steel wire in I-beam wheel unwrapping wire exit, support wheel is supported on the steel wire in I-beam wheel unwrapping wire exit, described limit switch is fixedly installed on the little boat supporting frame, the position of limit switch on described little boat supporting frame is corresponding with position, fabric wheel whereabouts, described wireless launcher is fixed on the little boat supporting frame, and radio receiver is arranged at outside the little boat supporting frame.
Near fracture of wire occurs in I-beam wheel unwrapping wire exit, behind the steel wire fracture, the broken end rear end can be scattered by stress effect bounce-back to I-beam wheel, fabric wheel loses the support whereabouts of steel wire simultaneously, touch limit switch, connect power supply and make wireless launcher send local flaw signal, radio receiver is received radio signal and is sent the stubble warning device instruction equipment stubble warning device is stopped.
Filament breakage detection apparatus for steel stranded wire of the present invention can not produce the fracture of wire false alarm.

(5) specific embodiment
Filament breakage detection apparatus for steel stranded wire of the present invention such as Fig. 2, shown in Figure 3 adopt radio transmission, reception technique to transmit fracture of wire information.It mainly is made up of fabric wheel 2, support wheel 3, limit switch 4, canoe support 5, wireless launcher 6 and radio receiver.
Described fabric wheel 2 is cantilever-shaped and is rotatably connected on the canoe support 5, support wheel 3 is fixedly connected on the canoe support 5, fabric wheel 2 is pressed on the steel wire in I-beam wheel unwrapping wire exit 1, support wheel 3 is supported on the steel wire in I-beam wheel unwrapping wire exit 1, limit switch 4 is fixedly installed on the canoe support 5, the position of limit switch 4 on described canoe support 5 is corresponding with position, fabric wheel 2 whereabouts, wireless launcher 6 is fixed on the canoe support 5, radio receiver is arranged at outside the canoe support 5, and the semi arch circuit wire detecting device is arranged at the bow of steel strand wires production equipment and is with 8 outsides.
Concrete operation principle is as follows:
During ordinary production, fabric wheel 2 is pressed on the steel wire in I-beam wheel unwrapping wire exit 1, because the effect of support wheel 3 no matter how crooked steel wire is, can not produce the fracture of wire false alarm.Near fracture of wire occurs in I-beam wheel unwrapping wire exit 1, behind the steel wire fracture, the broken end rear end can be scattered by stress effect bounce-back to I-beam wheel 9, fabric wheel 2 loses the support whereabouts of steel wire simultaneously, touch limit switch 4, connect power supply and make wireless launcher 6 send local flaw signal, canoe support 5 outer radio receivers are received radio signal and are sent the stubble warning device instruction equipment stubble warning device is stopped.Equipment was out of service fully in equipment received after the warning cutoff command in 7 seconds.To produce Φ 15.24mm steel strand wires is example, 90 meters/minute of ordinary production speed, and broken end front end steel wire can continue to move about 5.2 meters in this section period, and bow is with 8 to rotate about 24 and change, and reduces to touch the probability that the steel wire that scatters on the I-beam wheel causes that disconnected bow is with minimum.
If fracture of wire occurs in from circuit wire detecting device bow far away and is with, broken end front end steel wire continues to move ahead, and broken end rotates with the bow band and fallen out by centrifugal forces affect, may touch semi arch circuit wire detecting device 7 and stop.Even touch less than this circuit wire detecting device, broken end continues to move ahead, and must run into circuit wire detecting device at the pressing mold place and stops.Broken end rear end steel wire is rebounded by the internal stress effect, if eject I-beam wheel unwrapping wire import department 1, just as mentioned above, if bullet does not go out I-beam wheel unwrapping wire import department 1, the steel wire on the I-beam wheel does not scatter, and disconnected bow zoning can not take place.
The emitter of this covering device electric part adopts dry cell power supply, and the power supply of emitter does not have connection when normally moving owing to equipment, not power consumption, and dry cell can use continuously above 1 year.Emitter has the indication of under-voltage indicator lamp, and local flaw signal output is arranged after fracture of wire takes place.Receiving system provides 24V dc source by equipment, can be transferred to computer display screen to signal by PLC after receiving local flaw signal.The equipment operator can be directly acquainted with equipment fracture of wire situation by computer.
After a production line comes into operation, obtained good result with upper type.Average fracture of wire false alarm is 28 times/month before the 2# wire twisting machine repacking, repacking back fracture of wire false alarm≤2 time/month, and bow band did not so far break.Therefore repacking use on all 4 steel strand wires production equipments.
