Description
Technical field
The utility model relates to measurement mechanism, particularly the measuring a kind of measurement mechanism that can eliminate the middle wave influence of coiled material automatically of coiled material.
Background technology
Along with domestic and international used coiled material trend, high-strength panel replaces the amount of general sheet material more and more.The slab crosscut unit that matches with hot rolling line is the machining production line that thick specification, high-strength plate is involved in capable scale or non-cutting to length, the mode fling shear shear ability of plate production line is big, can reach per minute shears for 13 times continuously, sheared length 2000～16000mm, its steel plate length is sheared the tolerance range of control, dimensional tolerence is 0+3mm in the time of＜3 meters, and the dimensional tolerence in the time of＜5 meters is 0+4.3mm, and the dimensional tolerence in the time of 〉=8 meters is 0+6mm.
The equipment that the control mould is cut the length shearing is to measure dolly, this dolly is promoted, is depressed by hydraulic cylinder control, when dolly four measuring running roller is pushed down steel plate, the plate face of motion drives the dolly wheel by the friction force with wheel, the wheel that rotates meshes by internal gear, rotational angle is passed to central gear, central gear is passed to angle by universal-joint spindle the rotor of tech-generator, control system is by the lineal measure of the pulse signal judgement plate face of tech-generator, the shear time of decision shearer.Measuring dolly has higher measuring accuracy under straight steel plate situation, precision can reach 2～5mm.Yet run into intermediate wave shape wave steel plate, measure the measuring accuracy of dolly and have a greatly reduced quality, make the steel plate length overlength of mould shearing, as: mould is cut sheared length and is set 6015mm, actual sheared length 6065mm or 6075mm.Super margin tolerance 35mm or 45mm.(the long steel plate margin tolerance of 6000mm is 0～30mm).
Mould is cut pinch roll, and to pinch steel plate be that mould is sheared the input steel plate, measure the running roller tech-generator that under steel plate drives, turns around and send 1000 pulses, in four wheels, have only front-wheel or trailing wheel to be pressed in operating steel plate, at this moment tech-generator can not send pulse, that is to say this section steel plate length physical presence and do not have measured come out, pulse-break, when four running rollers that test the speed all are pressed on the steel plate in service once more, tech-generator sends pulse once more, pulse before interrupting and after the pulse of measuring be input to computing machine, computing machine calculates the steel plate running length according to the pulse data that tech-generator provides, in case operating steel plate length reaches the steel plate length that sets, computing machine is sheared to send to mould and is sheared instruction.
There is an open defect in the design of above-mentioned existing measurement dolly:
Measure dolly when measurement has intermediate wave shape wave steel plate length, measure dolly four measuring roller under the hydraulic cylinder effect and pressing surface of steel plate, owing to driving the roller rotation roller that tests the speed that produces that tests the speed, the fluctuating of operating irregular middle wave height on the plate face, jumps, cause complete disengaging plate face of front and back wheel or contact pressure deficiency, cause asynchronous between front and back wheel wheel face and the plate face (or relative slip takes place), it is long to cause the calculating steel plate length of tech-generator to be lower than actual plate.
Summary of the invention
The purpose of this utility model is to design a kind of measurement mechanism that can eliminate wave influence in the middle of the coiled material automatically, makes the measurement running roller of measuring dolly be close to the protruding peak of waveform steel plate or recessed peak wheel face all the time and rotates constantly, avoids the test leakage phenomenon to take place.
For achieving the above object, the technical solution of the utility model is,
A kind of measurement mechanism that can eliminate wave influence in the middle of the coiled material automatically, it comprises, fixed frame comprises fixed support and is fixed in the forward and backward baffle plate at its two ends; The four measuring running roller is arranged at described fixed frame fixed support both sides in twos by bearing pin respectively; And connect mutually with the tech-generator rotor by universal-joint spindle, tech-generator connects mutually with Measurement and Control System, receives the pulse signal of tech-generator; The utility model also comprises, back up pad is individually fixed in described fixed frame both sides; Electromagnet housing is individually fixed on the back up pad of described fixed frame both sides, and corresponding respectively each measurement running roller; The electromagnet magnetic core and on the solenoid winding, be arranged in the electromagnet housing respectively.
Further, described electromagnet housing is ∏ shape.
During work,, the four measuring running roller is close on the yo-yo steel plate inflexibly, is guaranteed that four running rollers rotate with the steel plate operation, guarantee that the steel plate length precision of measuring is constant by the magnetic force of front and back electromagnet.
The beneficial effects of the utility model
The utility model is by installing electromagnet respectively in the left and right sides of measuring dolly fore-and-aft survey running roller, and the installation site of electromagnet on the directions X and the contact point between running roller wheel face and the plate face in full accord, to guarantee the direction consistent all the time with the contact pressure direction (vertical) of magnetic force with the contact plate face; Guarantee the magnetic force size by certain electric current: produce when jumping when measuring roller excess convexity peak or trench, the magnetic force of electromagnet can guarantee that the invariable throw-on pressure of measuring roller roll surface that guarantees of measuring roller roll surface contact friction force is attached on the waveform steel plate all the time.
