Technical field
The utility model relates to a kind of constant tension control system, particularly a kind of straight drawing machine take-up constant tension control system.
Background technology
In straight drawing machine take-up process, traction electric machine is with constant speed wire drawing.Along with the wire that twines on the take-up block is more and more, the take-up block diameter increases gradually.If do not carry out speed regulating control to the take-up motor this moment, when the take-up block linear velocity greater than the wire drawing machine hitch wheel on during linear velocity wiry, will influence quality wiry even cause fracture of wire, otherwise, when tension force is too small, can produce the sleave wrapping phenomena.For avoiding the generation of the problems referred to above, now at take-up a tension detecting apparatus is installed usually, this tension detecting apparatus has a straining pulley, wire is on straining pulley, and straining pulley is installed on the mobilizable tension arm, when the tension arm knee-action, the output frequency of output signal of telecommunication control take-up frequency converter, thereby the control tension arm is stabilized on the position, after the Programmable Logic Controller PLC process PID computing, and the speed of control take-up motor.But the machine space that this control system requires is big, and meticulous wire is processed with certain influence; Have bearing on the straining pulley in the tension detecting apparatus, need periodic maintenance to change; Device start or when stopping the position of straining pulley with respect to setting value certain skew is arranged, thereby tension force wiry also has certain skew.
The utility model content
The technical problems to be solved in the utility model is: to make and maintenance cost in order reducing, and to avoid tension force wiry to produce skew when starting and stopping, the utility model provides a kind of straight drawing machine take-up constant tension control system.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of straight drawing machine take-up constant tension control system, comprise the traction electric machine that is used to drive hitch wheel, be used to drive the take-up motor of take-up block, be used to control the traction electric machine frequency converter of traction electric machine speed, be used to control the take-up motor frequency conversion device of take-up motor torque, measure first encoder of traction electric machine rotating speed and second encoder of measurement take-up motor speed, the Programmable Logic Controller that also comprises control traction electric machine frequency converter speed and take-up motor frequency conversion device speed, described Programmable Logic Controller has the high-speed counter of the digital pulse signal that can read encoder output, and high-speed counter connects first encoder and second encoder.
The beneficial effects of the utility model are, the take-up of straight drawing machine take-up constant tension control system of the present utility model is directly controlled the torque of take-up motor, has omitted tension detecting apparatus, the space requirement of machine is little, and cost and maintenance cost have reduced; Simultaneously, torque is controlled simply when starting and stopping, and tension force wiry can not produce bigger skew, and is more consistent with the stable state after starting, and improved the quality of production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the take-up structural representation of the utility model straight drawing machine take-up constant tension control system.
Fig. 2 is the utility model straight drawing machine take-up constant tension control system electrical control schematic diagram.
Among Fig. 1: 1, hitch wheel, 2, take-up block, 3, backing roll.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Be the take-up structural representation of the utility model straight drawing machine take-up constant tension control system as shown in Figure 1, take-up comprises hitch wheel 1, backing roll 3 and the take-up block 2 that sets gradually, and the top that is around in the wire process backing roll 3 on the hitch wheel 1 directly is around in take-up block 2.
Be the utility model straight drawing machine take-up constant tension control system electrical control schematic diagram as shown in Figure 2, comprise the traction electric machine that is used to drive hitch wheel, be used to drive the take-up motor of take-up block, be used to control the traction electric machine frequency converter of traction electric machine speed, be used to control the take-up motor frequency conversion device of take-up motor torque, measure first encoder of traction electric machine rotating speed and second encoder of measurement take-up motor speed, the Programmable Logic Controller PLC that also comprises control traction electric machine frequency converter speed and take-up motor frequency conversion device speed, Programmable Logic Controller PLC has the high-speed counter of the digital pulse signal that can read encoder output, and high-speed counter connects first encoder and second encoder.Along with the wire on the take-up block is more and more, the radius of take-up block and the superincumbent wire integral body of winding is increasing, if the moment of take-up motor is constant, tension force then wiry can be more and more littler, so the set-point of torque is not a steady state value.The high-speed counter of Programmable Logic Controller PLC reads the digital pulse signal of first encoder and the output of second encoder by bus, thereby obtains the speed of traction electric machine and the speed of take-up motor.Radius R=K * the V1/V2 of take-up block and the superincumbent wire integral body of winding, wherein K is a constant, and V1 is a traction electric machine speed, and V2 is the take-up motor speed.The pass of wire tension force F and take-up motor torque T is T=F * R, i.e. take-up motor torque T=K * F * V1/V2.Programmable Logic Controller PLC dynamically sets the moment of take-up motor according to take-up motor torque calculating formula, thereby stablizes control tension force wiry.
