Description
Technical field
The invention belongs to steel rolling process field, more particularly to a kind of it is used to prevent the control method of cold-strip steel circle shear steel-fastening.
Background technology
At present, circle shear has a wide range of applications on cold rolled strip steel production line, and being especially in the discontinuous unit such as rewinding must can not
Few key equipment.Find often occur problems with process of production, directly affect the fortune of equipment by use for many years
Line efficiency, and solved without effective technical measures.
Circle shear is typically designed at the middle part of unit, and front end ensures added with strip position regulator when making strip by circle shear
On unit centre line position, so as to ensure that strip both sides cutting edge is neat.But when being due to that strip throws tail, uncoiler tension force disappears
Lose, strip position regulator does not have due effect, cause throwing tail moment tail part of band steel to offset to one side, when skew width
When spending larger, strip side is cut less than side, and opposite side strip jam is between disc shear edge and framework, and the lighter is by jam
Strip cleared out from gap, it is necessary to waste the fault handling time of more than 2 hours；The heavy then steel disk of jam is laminated, and is made
Shut down into device damages such as strip steel at entry position detections and for a long time, cause larger economic loss, or even personal injury accident occur.
The content of the invention
The present invention is intended to provide a kind of steel-fastening that can detect and find in time strip tends to, it is to avoid the generation of steel-fastening accident, so as to subtract
Few causality loss, that improves unit operation efficiency prevents the control method of circle shear steel-fastening.
Therefore, the technical solution that the present invention is taken is：
A kind of to prevent the control method of circle shear steel-fastening, its specific method is：
(1) base for carrying chute is bolted respectively in the both-side opening degree framework upper of dividing a word with a hyphen at the end of a line of circle shear, before base
End is provided with long range mirror retroreflective photoelectric sensor perpendicular to belt steel surface, mirror retroreflective photoelectric sensor away from belt steel surface it is vertical away from
From for 200~300mm, mirror retroreflective photoelectric sensor is divided a word with a hyphen at the end of a line 30~80mm of frame edge away from opening degree.
(2) lower frame is divided a word with a hyphen at the end of a line with being respectively mounted one piece on mirror retroreflective photoelectric sensor correspondence position in the both-side opening degree of circle shear
Reflex reflector lens.
(3) mirror retroreflective photoelectric sensor is connected with straightener PLC, establishment PLC prevents steel-fastening control program；And in operating room
Interior setting audible-visual annunciator.
(4) occur serious sideslip during strip is divided a word with a hyphen at the end of a line, and when will appear from steel-fastening accident, side strip is in mirror reflected light
On position between electric transducer and reflex reflector lens, so that the reception signal of the side mirror retroreflective photoelectric sensor is blinded by, mirror reflection
Photoelectric sensor sends steel-fastening pre-warning signal to PLC.
(5) PLC is connected to after signal, prevents steel-fastening control program from controlling unit equipment speed reducing stopping, and logical by audible-visual annunciator
Know operating personnel；Meanwhile, steel-fastening control program is prevented before operating personnel's hand-reset alarm, limits unit restarting.
(6) operating personnel's manual reset alarm after tail part of band steel state is confirmed and adjusted, unit resumes operation, so that
Realize the timely detection and control of circle shear steel-fastening accident.
Beneficial effects of the present invention are：
1st, the steel-fastening that accurately can detect and grasp strip tends to, and adopts an effective measure solve in time, it is to avoid steel-fastening accident
Generation.
2nd, can greatly reduce causality loss, improve unit operation efficiency, reduction spare parts consumption and maintenance cost, it is to avoid equipment and
Personal injury accident.
Brief description of the drawings
Fig. 1 is steel-fastening detection means installment state front view；
Fig. 2 is steel-fastening detection means installment state top view.
In figure：Divide a word with a hyphen at the end of a line framework 1, base 2, mirror retroreflective photoelectric sensor 3, circle shear 4, strip 5, reflex reflector lens 6.
Embodiment
The present invention prevents the control method of circle shear steel-fastening, including fabrication and installation detection means and the running status of strip 5 from detecting in real time
Two parts are controlled, by being used cooperatively with machine set PLC, whether is running status of the accurate detection strip 5 inside the circle shear 4
Generation deviation, once deviation crosses senior general's triggering alert program to reach the purpose for avoiding steel-fastening accident.Specific method is：
1st, circle shear 4 both-side opening degree divide a word with a hyphen at the end of a line the top of framework 1 be bolted respectively one carry chute base 2, bottom
Seat 2 can carry out front and back position adjustment by chute.The front end of base 2 is respectively provided with long range mirror reflection perpendicular to the surface of strip 5
Photoelectric sensor 3.To prevent from damaging, vertical range of the mirror retroreflective photoelectric sensor 3 away from the surface of strip 5 is 250mm, mirror reflection
Edge 50mm of the photoelectric sensor 3 away from framework 1 of dividing a word with a hyphen at the end of a line.
2nd, divide a word with a hyphen at the end of a line and pacify respectively on the bottom of framework 1 and the correspondence position of mirror retroreflective photoelectric sensor 3 in the both-side opening degree of circle shear 4
Fill one piece of reflex reflector lens 6.
3rd, mirror retroreflective photoelectric sensor 3 is connected with straightener PLC, establishment PLC prevents steel-fastening control program；And in operation
Indoor setting audible-visual annunciator.
4th, occur serious sideslip during strip 5 is divided a word with a hyphen at the end of a line, and when will appear from steel-fastening accident, the strip 5 in left side is located just
On position between mirror retroreflective photoelectric sensor 3 and reflex reflector lens 6, so as to be blinded by the reception of mirror retroreflective photoelectric sensor 3
Signal, mirror retroreflective photoelectric sensor 3 sends steel-fastening pre-warning signal to PLC.
5th, PLC is connected to after signal, prevents steel-fastening control program from controlling unit equipment speed reducing stopping, and notified by audible-visual annunciator
Operating personnel；Meanwhile, steel-fastening control program is prevented before operating personnel's hand-reset alarm, limits unit restarting.
6th, manual reset alarm after operating personnel are confirmed and adjusted to the tail state of strip 5, unit resumes operation, from
And realize the timely detection and control of the steel-fastening accident of circle shear 4.
