Abstract
The utility model discloses a hydraulic servo screwdown for a fine leveler, which comprises a hydraulic oil cylinder (1), an upper roll (2), a lower roll (3) and an upper roll seat (4), and is characterized in that the hydraulic oil cylinder (1) is a servo cylinder; a pressure sensor (5) and a displacement sensor (6) are mounted on the hydraulic oil cylinder (1); the hydraulic oil cylinder (1) is externally connected with a hydraulic station (8) by an electro-hydraulic servo valve (7); and the pressure sensor (5), the displacement sensor (6) and the electro-hydraulic servo valve (7) are externally connected with a DP (data processing) bus electric control device (9) and a touch screen (10). A CPU (central processing unit) operates according to various set parameters of the touch screen automatically when the hydraulic servo screwdown operates, and obtains digital visible process numerical values. The numerical values are transmitted to the touch screen for monitoring, and also sent to the electro-hydraulic servo valve to control oil flow, so as to be converted to precise operation of the oil cylinder. Controllable lifting speed, screw-down pressure and screw-down amount can be realized, right and left heights of the upper roll are adjustable, a steel belt does not deviate, and the leveling effect is good.
Description
Technical field
The utility model belongs to the spiral welded pipe process unit, concrete relates to a kind of smart level(l)ing machine hydraulic servo screwdown gear.
Background technology
Level(l)ing machine is the crucial process equipment of spiral welded pipe unit, main leveling work of being responsible for producing the Raw steel band.Because the spiral welded pipe raw materials for production are to use hot rolled strip, will produce the open defects such as wave is curved, crescent moon is curved, basin type, uneven thickness after raw material is opened.Not sideslip and flatness when guaranteeing raw material plate edge machined and moulding, level(l)ing machine plays vital effect.In the prior art, level(l)ing machine top roll screwdown gear mostly uses worm and gear machinery to depress and the hydraulic jack screw-down structure.The deficiency that worm and gear machinery screw-down structure exists is: because the unavoidable accumulated error that produces each parts in the processing and manufacturing process, the level(l)ing machine top roll is depressed to be uneven about rear, caused very large difficulty for the adjustment of level(l)ing machine, can cause steel belt deviation and plate position just waiting problem in the use procedure, just walk by the plate position so will lift every now and then the level(l)ing machine top roll in the production process.The deficiency that the hydraulic jack screw-down structure exists is: the steel belt deviation problem is difficult to solve, and it is curved unstable with the curved steel pipe forming that makes of S to produce crescent moon when causing plate edge machined, and product quality can not get good assurance.
Summary of the invention
The purpose of the utility model, be uneven about when being to solve prior art and depressing, movement velocity such as can not finely tune slowly at the deficiency, a kind of smart level(l)ing machine hydraulic servo screwdown gear is provided, it can control pressing speed, drafts, left and right sides roller seat can be finely tuned, and data can show and can store, and improve flatness and the welding quality of raw material.
For reaching above-mentioned purpose, the utility model is by the following technical solutions: the utility model comprises: hydraulic jack, top roll, lower roll, top roll roller seat, it is characterized in that: hydraulic jack is servo-cylinder, pressure sensor, displacement transducer are housed above it, hydraulic jack is by the external Hydraulic Station of electrohydraulic servo valve, pressure sensor, displacement transducer and electrohydraulic servo valve external DP bus electric control gear and touch-screen.
The utility model is taked above technical scheme, has following beneficial effect: the utility model is equipped with pressure sensor, displacement transducer at hydraulic jack, and hydraulic jack is precisely controlled.By the control of DP bus electric control gear, technical parameter is inputted by touch-screen.The utility model carries out computing according to the parameters that touch-screen sets automatically by CPU when operation, then draw digitized visible process numerical value by CPU.Reach touch-screen in order to monitor on the one hand; On the other hand this numerical value is sent into electrohydraulic servo valve the flow of oil is controlled, thereby be converted into the accurate operation of oil cylinder.The utility model has been realized rising or falling speed, has been depressed controlling of pressure and drafts, has highly realized adjustablely about top roll, guarantees not sideslip of steel band, and leveling is effective, and it is simple to operation to rectify a deviation.Various data can be accomplished instant playback, are easy to observe, and can carry out data storing.
