Abstract
The invention relates to a shearing control system for a fixed-length shear and a use method thereof. The shearing control system comprises an induction type detector, a PLC module and a driver; wherein the induction type detector comprises a deceleration induction type detector and a stoppage induction type detector. The deceleration induction type detector and the stoppage induction type detector are connected with the PLC module parallelly. The PLC module is connected with the driver. Compared with the prior art, the shearing control system has advantages of simple control and high stability. The shearing control system prevents a problem of an offset of a fixed-length shear crankshaft of an encoder from a reference position caused by interferences of external factors. Furthermore the shearing control system has advantages of simple structure, high reliability and high practicability.
Description
Technical field
The invention belongs to shearing property technical field, relate to a kind of fixed size scissors shearing property system and using method thereof.
Background technology
Fixed size scissors is for steel plate cut-to-length equipment in heavy and medium plate mill cutting operation, during fixed size scissors work, to treat that shear-steel plate is transported in fixed size scissors by rollgang to implement to shear, current fixed size scissors automatic shearing controls mostly to adopt the pulse coder counting be installed on bent axle, under corresponding PLC program is supported, automatically shearing task is completed from starting to stopping, but because the precision electronic element of decoder internal is higher to outside requirement for environmental conditions, at work by site environment temperature, the impact of the factor such as mechanical oscillation and repeat count, bring out encoder and send out pulse by mistake, there is deviation in counting, make fixed size scissors upper knife edge often can not stop at reference position, blade opening degree is caused to diminish, affect steel plate to pass through smoothly, operative employee transfers auto state continuation production again to after often first will manually returning to reference position thus, thus affect rhythm of production, also occur time serious " connecting cutter ", cut up steel plate, therefore, fixed size scissors automatic shearing is not controlled has had a strong impact on steel plate shearing lumber recovery and rhythm of production.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the invention provides a kind of fixed size scissors shearing property method, its can efficient solution determine fixed size scissors automatic shearing time can not stop at the problem of benchmark position, there is structure simple, precise control, the feature such as practical.
The present invention solves the technical method that its technical problem adopts: a kind of fixed size scissors shearing property system, comprise induction type detector, PLC module, driver, wherein induction type detector comprises deceleration induction type detector and stops induction type detector, deceleration induction type detector and stopping induction type detector are connected with PLC module respectively, and PLC module is then connected with driver again.
The using method of this fixed size scissors shearing property system, its job step is:
Fixed length steel plate to be sheared is transported in fixed size scissors by A, rollgang;
B, startup automatic shearing button, scale cuts off steel plate;
C, blade leave steel plate, and bent axle pointer sends reduce-speed sign to PLC module thus by deceleration induction type detector;
D, fixed size scissors decelerate, pointer sends stop signal to PLC module thus by stopping induction type detector;
E, PLC module then send a signal to driver, and driver makes fixed size scissors bent axle stop at reference position.
Further, deceleration induction type detector in described step C sends opportunity from reduce-speed sign to PLC module shears in complete blade leaves steel plate at fixed size scissors, namely from the counterclockwise 270 degree of places of benchmark zero-bit, deceleration specified rate is that fixed size scissors starts 60% of specified rate.
Further, the stopping induction type detector in described step D sends the opportunity of stop signal from the counterclockwise 330 degree of places of benchmark zero-bit to PLC module, and it stops specified rate to be 0.
Described deceleration induction type detector and stopping induction type detector are arranged on both sides, fixed size scissors crankshaft-link rod center respectively.
Described induction type detector has induction pointer, and induction pointer to be installed on crankshaft-link rod and to rotate with crankshaft-synchronous.
The invention has the beneficial effects as follows: compared with prior art, the present invention controls simply, good stability, avoid prior art because of encoder by external factor interference cause fixed size scissors bent axle to depart from the problem of benchmark position, there is structure simple, the features such as reliability is high, practical.
Accompanying drawing explanation
Fig. 1 is fixed size scissors shearing property systematic square frame structural representation of the present invention.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
See Fig. 1, a kind of fixed size scissors shearing property system, comprise induction type detector, PLC module, driver, wherein induction type detector comprises deceleration induction type detector and stops induction type detector, deceleration induction type detector and stopping induction type detector are connected with PLC module respectively, and PLC module is then connected with driver again.
The using method of this fixed size scissors shearing property system, its job step is:
Fixed length steel plate to be sheared is transported in fixed size scissors by A, rollgang;
B, startup automatic shearing button, scale cuts off steel plate;
C, blade leave steel plate, and bent axle pointer sends reduce-speed sign to PLC module thus by deceleration induction type detector;
D, fixed size scissors decelerate, pointer sends stop signal to PLC module thus by stopping induction type detector;
E, PLC module then send a signal to driver, and driver makes fixed size scissors bent axle stop at reference position.
Further, deceleration induction type detector in described step C sends opportunity from reduce-speed sign to PLC module shears in complete blade leaves steel plate at fixed size scissors, namely from the counterclockwise 270 degree of places of benchmark zero-bit, deceleration specified rate is that fixed size scissors starts 60% of specified rate.
Further, the stopping induction type detector in described step D sends the opportunity of stop signal from the counterclockwise 330 degree of places of benchmark zero-bit to PLC module, and it stops specified rate to be 0.
Described deceleration induction type detector and stopping induction type detector are arranged on both sides, fixed size scissors crankshaft-link rod center respectively.
Described induction type detector has induction pointer, and induction pointer to be installed on crankshaft-link rod and to rotate with crankshaft-synchronous.
Compared with prior art, the present invention controls simply, good stability, avoids prior art and causes fixed size scissors bent axle to depart from the problem of benchmark position because of encoder by external factor interference, have structure simple, the features such as reliability is high, practical.
