Abstract
The utility model discloses an automatic constant-tension coiling control system of a shearing machine. The control system comprises a coiling machine used for coiling a coiled stock and a deflector roll used for discharging the coiled stock, wherein the deflector roll is parallel to the shearing shaft of the coiling machine, the deflector roll is arranged on a moving device capable of moving along a straight line vertical to the direction of the shearing shaft, and the moving device is controlled by a servo motor. The control system further comprises a measuring device used for measuring the diameter of the coiled stock on the coiling machine, wherein the measuring device inputs the diameter numerical value of the coiled stock in the central controller, and the central controller converts the diameter of the coiled stock into the position of the moving device according to the formula shown in the specification, converts the position signal into a pulse signal and transmits the signal to the servo motor so as to maintain the invariable included angle between a belt material between the coiling machine and the deflector roll and the horizontal line. The control system can maintain constant coiling tension during the coiling process and has the advantages of simple structure and good economical efficiency.
Description
Technical field
The utility model relates to a kind of Coiling Tension Control equipment of cutter.
Background technology
The coiling tension of cutter can constantly change with the increase of coil diameter, and the functional relation between them is, and is as shown in Figure 1.Band batches under the tension force that changes, and winding power changes, and can cause problems such as roll coil of strip tension, turriform, staggered floor, adhesion, especially can produce the uneven problem of internal stress, has strengthened the difficulty that strand-anneal(ing) is handled, and directly influences strip quality.
The permanent tension coiling device of existing band generally adopts torque motor, reductor, shaft coupling, like Chinese patent No. 201120074143 " permanent tension force cable rolling electric supply installation ", No. 200520139779 " the permanent tension control mechanisms of the coiling of loom ".Though this tension-adjusting gear uses general, mechanism is complicated, cost is higher.
Utility model is held
The utility model will overcome complicated, the with high costs shortcoming of permanent tension coiling equipment mechanism of existing band, provides a kind of simple in structure, economic cutter permanent tension coiling automatic control system.
The permanent tension coiling automatic control system of cutter; Comprise the coiling machine that is used to batch the roll coil of strip, the deflection roll of emitting the roll coil of strip; Described deflection roll is parallel to the axle of cutting of described coiling machine; It is characterized in that: described deflection roll is arranged on one can be along on the mobile device that moves perpendicular to the described direction straight line of cutting axle, and described mobile device is controlled by a servomotor; Comprise that also one is used to measure the measurement mechanism of the diameter of the roll coil of strip on described coiling machine; Described measurement mechanism is imported a central controller with the diameters of the roll coil of strip; Described central controller is converted into the diameter of the roll coil of strip according to following formula the position of described mobile device; And described position signalling is converted into pulse signal and flows to described servomotor, and band and the included angle B between the horizontal line kept between described coiling machine and the deflection roll are constant:
a＝b/sinB
Wherein a is the position numerical value of described mobile device; B is the diameters of the roll coil of strip on described coiling machine.
In coiling process, the diameter of the roll coil of strip on the coiling machine increases gradually, and under the control of central controller, mobile device moves to the direction away from coiling machine, makes that the angle between the band and horizontal line remains unchanged between coiling machine and the deflection roll.Thus, make the coiling tension of the roll coil of strip remain unchanged.
Description of drawings
Fig. 1 is the operation principle sketch map of the utility model, and wherein A position and B bit representation mobile device lay respectively at the state of two operating positions.
The specific embodiment
With reference to accompanying drawing:
The permanent tension coiling automatic control system of cutter; Comprise the coiling machine 1 that is used to batch the roll coil of strip, the deflection roll 4 of emitting the roll coil of strip; Described deflection roll 4 is parallel to the axle of cutting of described coiling machine 1; Described deflection roll 4 is arranged on one can be along on the mobile device that moves perpendicular to the described direction straight line of cutting axle, and described mobile device is controlled by a servomotor; Comprise that also one is used to measure the measurement mechanism of the diameter of the roll coil of strip on described coiling machine 1; Described measurement mechanism is imported a central controller with the diameters of the roll coil of strip; Described central controller is converted into the diameter of the roll coil of strip according to following formula the position of described mobile device; And described position signalling is converted into pulse signal and flows to described servomotor, and band 3 and the included angle B between the horizontal line kept between described coiling machine 1 and the deflection roll 4 are constant:
a＝b/sinB
Wherein a is the position numerical value of described mobile device; B is the diameters of the roll coil of strip 2 on described coiling machine 1.
In coiling process, the diameter of the roll coil of strip 2 on the coiling machine 1 increases gradually, and under the control of central controller, mobile device moves to the direction away from coiling machine, makes that the angle between the band and horizontal line remains unchanged between coiling machine 1 and the deflection roll.This makes the coiling tension of the roll coil of strip remain unchanged.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; The scope of the protection of the utility model should not be regarded as and only limit to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
