The manufacturer that has is that 1 workman opens 1 equipment, if when operating personnel leave, break, and the shutdown if machine is not reported to the police, admission machine will continue high-speed cruising, and possible damage equipment also may influence production safety.
Therefore, if when wire drawing is broken, machine can in time be shut down, and can guarantee that first equipment is safe in utilization; Second can shorten setting up time, especially in the wire drawing mainframe box, take place to break, can reduce and wear the modulus amount, enhance productivity greatly; Three are improved automation, reduce operating personnel's attention rate and working strength.
Summary of the invention
This wire break alarm device provides a kind of big wire drawing machine wire break alarm device at utmost point autostop in the short time when making big wire drawing machine that broken string take place.
The utility model is achieved by the following technical solution: a kind of big wire drawing machine wire break alarm device, comprise pay off rack, wire drawing main frame, annealing machine, storage rack, admission machine, its major technique feature is that the wire carrier of crossing of described pay off rack is provided with break alarm mechanism, described break alarm mechanism was that a circle hole is opened at the line edge of crossing of wire carrier, a sensor alignment hole wherein installs and fixes, and sensor is connected with master controller; Described sensor is near switch;
Stationary guide roller is one on the described wire carrier excessively, and deflector roll is installed in the copper bar and entered the wire carrier place; Cross hole that crossing of wire carrier leave at the line edge greater than external diameter near switch.
When this wire break alarm device can make big wire drawing machine that broken string takes place at utmost point autostop in the short time, no matter break occur in the admission machine, in the annealing machine, or the wire drawing main frame in, at broken string the automatic quick shutdown of machine takes place just to instruct in 1 second generally.Its principle is when according to copper bar or aluminium bar broken string taking place after entering the wire drawing main frame; pay off rack at first stops for line; the pay off rack guide wheel stops operating; therefore; whether a sensor is installed on a guide wheel of pay off rack is used for detecting guide wheel and rotates; if guide wheel does not rotate, then sensor produces the break alarm signal, makes the machine autostop.
Description of drawings:
Fig. 1 is this wire break alarm device schematic diagram;
Fig. 2 is big wire drawing machine wire break alarm device structural representation for the I place enlarged drawing of Fig. 1.
The specific embodiment:
Elaborate with regard to its implementation procedure below.
Fig. 1 is the big wire drawing machine schematic diagram of copper, and block diagram part (seeing Fig. 2 for details) wherein is a content of the present invention.During wire drawing, copper bar 7 is crossed wire carrier 8 by pay off rack 1 and is entered wire drawing main frame 2 in block diagram, and it is optional to enter annealing machine 3(behind the one-tenth line), arrive storage rack 4 again, enter admission machine 5 at last and be winding into dish.In the drawing process, the copper bar drove wire carrier and rotated; During broken string, the copper bar halts, and crosses wire carrier and stops operating.Whether rotated for surveying wire carrier, to be somebody's turn to do wire carrier makes shown in Figure 2, install one again near switch 6, like this, when guide wheel rotates, replace make-and-break signal near switch output, when guide wheel stops operating, export normally closed signal or often open signal near switch, primary control program just can judge whether according to the signal form near switch to break.For example the switching signal that received in 1 second of primary control program all is high level or all is low level, then judges and breaks, immediately quick shutdown and reporting to the police.
Fig. 2 is the block diagram part among Fig. 1, by cross wire carrier 8, near switch 6, deflector roll 9 each one form.A circle hole is opened at the edge of guide wheel, and a hole of aiming at wherein near switch installs and fixes, and deflector roll is installed in the copper bar and enters the guide wheel place.During near switch mating holes center, there is not induced signal, the output high level; Facing between the hole during guide wheel metal, induced signal is arranged, output low level near switch.When line was crossed in wire drawing, guide wheel rotated, maintain static near switch, thus output high level and low level alternately; Shut down or during broken string, copper bar and guide wheel be transfixion all, will be near switch facing to the guide wheel metal between hole or Kong Yukong, thus export constant high level or low level.A deflector roll is installed, can be prevented that the copper bar from skidding off the groove of wire carrier, guide wheel did not rotate and caused false alarm when avoiding line.Effective, accurate, timely for making near the signal of switch, should note following 3 points:
1, for guaranteeing the make-and-break signal quality near switch, the hole at guide wheel edge should be slightly larger than the external diameter near switch, like this, when near the switch mating holes, does not have induced signal fully, the output high level; During metal, induced signal is arranged, output low level between mating holes.
2, the speed of guide wheel rotation, and the size of guide wheel, decision is near the frequency of switch output high-low level, therefore, suitably increase the guide wheel external diameter, also just increase edge perforate quantity, under identical velocity of rotation, can improve signal output frequency, thereby increase the break alarm precision near switch.
3, because in the low speed wire drawing stage, it is slow to cross the wire carrier velocity of rotation, may cause false alarm, therefore master control program can be set alarm velocity according to actual conditions, promptly at the low-speed stage of start and close process, the shielding break alarm is opened after drawing speed arrives certain speed again.
As shown in Figure 2, all broken strings that takes place after the wire carrier that was somebody's turn to do can produce in the time of setting and report to the police, and produce a desired effect.
This warning device can use and the big wire drawing of copper, the big wire drawing machine of aluminium, and other has on the wire-drawing equipment of similar structures.
