Abstract
A horizontal laser beam passes through basic point of rolling central line on piercer and then irradiates an analog three-roller centering machine on its base, so as to measure rolling central line. The central line may be corrected by increasing or decreasing number of pads on the base. The method features high productivity and measuring precision (+/- 2.5 mm).
Description
The present invention relates to a kind of measurement correction technique that is applicable to the metal tube rolling mill rolling centerline.
The metal tube rolling mill rolling centerline is a very important datum line in the operation of rolling, and the height of rolling centerline precision will bring great influence to production and product quality, and it is very necessary therefore adopting high accuracy, high efficiency measurement correction technique.Traditional measurement modification method is to adopt a thin steel wire rope, two bolt at rope has the hammer of hanging down, with the framework that has truckle on two crossbeams steel wire rope is set up,, measure with ruler then and on the basis under the three roller centring machines, add and subtract pad and revise rolling centerline as rolling centerline with this.Because steel wire rope could be stretching after need striding across and pass many various machinery equipments, construction is got up, and very the difficulty fiber crops are numerous, also may influence other work.Because steel wire rope reaches more than 30 meter, because of the sagging error that causes of conducting oneself with dignity, and use ruler to measure, certainty of measurement is poor, and speed is slow, has had a strong impact on production and product quality.
Purpose of the present invention is intended to make improvements at problems of the prior art, measure correction technique to obtain the rolling center line of piercing mill that a kind of constructing operation is easy, speed is fast, precision is high, efficient is high, to satisfy the big needs of producing of steel and iron industry modernization.
For achieving the above object, the technical solution that proposes of the present invention is: with the laser beam of a level by being located at rolling centerline basic point irradiation on the punch memorial archway and being placed on that simulation three roller centring machines on the three roller centring machine bases are measured and by on the basis under the three roller centring machines, increasing or the method for minimizing pad is revised three roller centring machine rolling centerlines.
Accompanying drawing 1 is depicted as measuring technique schematic diagram of the present invention.
Accompanying drawing 2 is depicted as simulation three roller centring machine structural representations of the present invention.
Below in conjunction with Figure of description and embodiment the present invention is further described: as shown in the figure, a high-precision laser transit 8 is installed on the vertical lift adjuster 5, and place it on the rolling centerline basic point 7 before the pusher seat 6, a weight below it aims the place.This laser transit 8 is launched the laser beam 1 of the easy identification of a level, as red laser beam, regulate vertical lift adjuster 5 and make laser beam 1 shine simulation three roller centring machines 9 that are placed on the three roller centring machine bases 4 by a rolling centerline basic point 3 that is located in the punch board harm 2.Simulate that three roller centring machines 9 are established two straight preceding targets parallel to each other 11 by base plate 10 and vertical base plate 10 and back target 12 is formed, on preceding target 11, have an aperture 13, its diameter is a bit larger tham laser beam 1 diameter, portrayal has " a ten " word 14 on the target 12 of back, should " ten " word center and the vertical front and back of the line target 11,12 at aperture 13 centers, the distance of aperture 13 centers to the centration axis of the distance of base plate 10 bottom surfaces and centring machine to its support bottom surface equates that target 11,12 spacings in front and back equate with the centration axis line length of three roller centring machines.Analog machine 9 is placed on respectively on the basis 4 of each three rollers centring machine position, with aperture 13 alignment 1, if laser beam 1 passes " ten " word 14 centers of failing behind the aperture 13 to shine on the target 12 of back, can on the basis under the analog machine 94, add and subtract pad 15, pass aperture 13 until laser beam 1 and shine " ten " word 14 centers, measure and revise rolling centerline with this.When online installation three roller centring machines, this is decorated with the garden rod of " ten " word to clamp an end face axle center with centring machine, again with this garden rod " ten " word center actual measurement checking of laser beam 1 irradiation.
Compared with prior art, the present invention is owing to adopted laser beam to cooperate simulation three roller centring machines that rolling center line of piercing mill is measured correction, operation becomes simple and efficient, and operating efficiency and certainty of measurement increase substantially, and the rolling centerline precision can reach ± 2.5mm even higher. Measure the correction rolling centerline with out-of-date methods, product wall unevenness rate reaches 17.5%, and adopts the technology of the present invention, and wall unevenness rate＜10% has increased substantially production efficiency and product quality.
