Description
Technical field
The present invention relates on the cold-rolling mill group job line to plate shape device particularly a kind of on-line tension testing agency.
Background technology
More and more higher to the requirement of plate shape on cold-rolling mill group job line, existing settling mode is in the operation of rolling strip to be carried out rolling with (stock) tension.And tension force is given, calculates the moment of motor by the galvanometer of motor, draws this moment relative value tension force on the strip then.This indirect method realizes the control of relative value tension force, and control accuracy is low relatively.
Summary of the invention
The purpose of this invention is to provide a kind of on-line tension testing agency, it simple in structure, performance is safe and reliable, is used for direct tension closed loop control.
The object of the present invention is achieved like this, design a kind of on-line tension testing agency, comprise stationary roll 2, last wrinkle resistant roller 3 that hydraulic pressure is cut, it is characterized in that: which comprises at least one and survey a mechanism, surveying a roller 4 is fixed on the cylinder pedestal 1 with elevating function, survey to open roller 4 that cut at hydraulic pressure and between the wrinkle resistant roller 3, make cold rolled sheet 5 wear band through stationary roll 2, survey when opening roller 4 and going up wrinkle resistant roller 3, survey the cold-reduced sheet 5 of opening roller 4 upper surfaces and the hydraulic pressure of front end and cut last wrinkle resistant roller 3 formation angles with the back; It is tension pick-up 6 that the survey that forms angle is opened below the roller 4, and tension pick-up 6 is connected with testing circuit, stationary roll 2, surveys and opens roller 4 and reach upward the distance value between wrinkle resistant roller 3 levels and fix.
Described wrinkle resistant roller 3 position that descends and the position distance value that a survey roller 4 rises fixed.
It is pressure detecting instrument that mechanism is opened in described survey.
Characteristics of the present invention are: measuring the online smooth tension force of strip by survey opening a mechanism, so that better carry out tension force optimization, the plate shape of strip being controlled.Have and calculate accurately, sensitive reliable, operation, easy to maintenance needs can be extensive use of in the tension force control in all of cold rolling unit.Particularly strip production meaning is bigger.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is that embodiment tension force detects schematic diagram;
Fig. 2 is an embodiment of the invention structural representation.
Among the figure: 1, cylinder pedestal; 2, stationary roll; 3, go up wrinkle resistant roller; 4, survey a roller; 5, cold rolled sheet; 6, tension pick-up.
The specific embodiment
As shown in Figure 2, survey to open a roller 4 and be fixed on the cylinder pedestal 1 with elevating function, survey open roller 4 stationary roll 2 that hydraulic pressure is cut and between the wrinkle resistant roller 3.When cold rolled sheet 5 is worn band, survey a roller 4 and be lower than steel band, go up wrinkle resistant roller 3 simultaneously and be higher than the steel band position, promptly survey a roller 4 and do not contact with steel band with last wrinkle resistant roller 3.After wearing the end of tape, survey a roller 4 and rise to extreme position, simultaneously, go up wrinkle resistant roller 3 and under the effect of oil cylinder, rise to extreme position in the effect of oil cylinder.Steel band is opened roller 4 with stationary roll 2, survey and is gone up wrinkle resistant roller 3 surfaces and contacts this moment, and the cold rolled sheet 5 that roller 4 top upper surfaces are opened in survey forms angle a and b with the stationary roll 2 of front end and the last wrinkle resistant roller 3 of back; When stationary roll 2, survey to open roller 4 and go up distance value between wrinkle resistant roller 3 levels fix and go up position that wrinkle resistant roller 3 descends with survey open roller 4 rises the position distance value fixedly the time angle a and b be constant.In order to measure the tension force of cold rolled sheet 5, survey to open under roller 4 bearing blocks tension pick-up 6 is arranged, come the detected pressures signal as pressure sensor (usually change or the electric capacity quantitative change provides the device of the signal of telecommunication) by strain resistor or displacement, pressure signal is amplified and analog-to-digital conversion by the testing circuit that is electrically connected with it again, shows last tension force by display circuit after the processor processing.Certainly last tension force will deduct and survey the weight of opening mechanical parts such as roller, and the numerical value that makes its demonstration is exactly the actual tension value of online strip.It comprises surveying for one opens mechanism, and surveying a mechanism is pressure detecting instrument.
Its principle of the present invention is: survey a mechanism when cold rolled sheet is worn band and drop to lowest order, after wearing the end of tape, survey a mechanism and under the effect of hoist cylinder, rise to limit position, this template band is opened a roller and has been formed cornerite surveying between the stationary roll that last wrinkle resistant roller and hydraulic pressure are cut, and surveys to open a mechanism and calculate the tension force of strip this moment according to cornerite.
Fig. 1 shows the operation principle of tensometer, as shown in Figure 1, strip tension force vertical direction make a concerted effort be:
N＝T×sina+T×sinb
＝T×(sina+sinb)
Thereby derive:
Tension force T=N/ (sina+sinb);
Wherein: T surveys to open the actual value that instrument obtains;
A, the b angle value can obtain in the geometrical relationship from Fig. 2.
Therefore, need only the signal that detects the N that makes a concerted effort of vertical direction by pressure sensor, amplify processing, in the substitution formula, just can conveniently provide tension force T by treatment circuit.Because it is disclosed technology that pressure sensor and testing circuit detect the N that makes a concerted effort, and does not do more descriptions here.
By the above-mentioned theory explanation, be not difficult to know that the present invention has characteristics simple in structure, that performance is safe and reliable.Not only optimized the tonometry on the strip flat line, certainty of measurement is improved greatly, accurately realized strip plate shape is controlled.
