Abstract
The invention discloses a monitoring method for steel clamping of a disk shear. The method comprises the following steps of: detecting the rotation speed of a motor of a scrap shear by using an encoder, calculating the running distance of band steel, judging whether a steel clamping accident happens by combining an actually measured moment value and a set moment value of the scrap shear, and sending stopping and alarming control signals. The invention also discloses a monitoring device for steel clamping of the disk shear. By the monitoring device and the monitoring method, steel clamping accidents can be automatically monitored and timely found, so that the accidents are prevented from deteriorating, unnecessary stopping is avoided, and the working efficiency is improved.
Description
Technical field
The present invention relates to the steel-fastening detection technique, more particularly, relate to a kind of circle shear steel-fastening supervising device and method.
Background technology
Circle shear is for the equipment of shearing steel edge portion.Because certain customers need sheared plates, so be designed with circle shear at hot fine rolling crosscut unit, be used at band steel running its burr being excised, the side cut amount of general both sides is 22-50mm.Circle shear generally is comprised of transmission side and two groups of cutting edges of fore side, and every group of cutting edge has upper and lower two cutting edges, and circle shear is installed on the circle shear frame, is connected with gear distribution box by universal drive shaft, by the circle shear motor-driven.Fore side is connected the circle shear motor and is connected by gangbar with transmission side in addition, and is synchronous to guarantee transmission side and two groups of cutting edge speed of fore side.What usually, circle shear downcut also carries out cropping cut by the scrap cutter of being located at a side with the steel slitter edge.
Yet, in hot rolling finishing crosscut unit production process, there are the reasons such as camber owing to incoming band steel, the steel-fastening accident often occurs in the circle shear zone.By analysis, the steel-fastening accident mainly contains following several reason: 1, circle shear only clips to the side with steel, and opposite side is not sheared; Although 2, circle shear has clipped to band steel both sides, wherein a side does not enter scrap cutter smoothly, but jam is between circle shear and scrap cutter.No matter the steel-fastening accident of which kind of situation occurs, and consequence all is serious.General steel-fastening causes the long-time shutdown of production line to I haven't seen you for ages, serious even can damage equipment.And the steel-fastening discovery time is more late, and consequence is more serious, therefore must in time find steel-fastening, takes measures as early as possible the Accident prevention extension.
At present, also do not have the automatic monitoring equipment of special steel-fastening, just observe chute by camera, find that the chute of scrap cutter below falls without broken limit, namely think steel-fastening may occur.But the operation of broken limit is after circle shear is sheared; adopt above-mentioned monitor mode; can't find timely and effectively steel-fastening, and if the broken limit after the normal cropping cut be deposited in the chute to fall, can cause being mistaken for steel-fastening; need frequent shutdown to arrive on-the-spot affirmation; and in fact, when broken limit is stacked into certain altitude in chute after, can fall voluntarily; therefore so unnecessary shutdown inspection has not only affected operating efficiency, but also has increased labour intensity.
