Abstract

The utility model belongs to the control field of steel rolling automation, being especially suitable for a control device for detecting the roller gap of a hydraulic rolling mill. The utility model is composed of a connecting rod connected with the top end of a piston in a hydraulic oil cylinder of the hydraulic rolling mill, the other end of the connecting rod is connected with an iron core of a displacement sensor, the top end of the oil cylinder is provided with a sleeve barrel flange, a sleeve barrel, a tuning sleeve, etc., the displacement sensor is arranged in the tuning sleeve, and designers can regulate the position of the sensor through the tuning sleeve and then screw a locking nut and a fastening screw. Compared with the prior art, the utility model has the advantages of high detecting precision, convenient installation, debugging and maintenance, no external interference when the displacement sensor works, etc.

Description

Hydraulic mill is depressed checkout gear
The utility model belongs to automation of rolling control field.Be specially adapted to hydraulic pressure and depress the detection control apparatus of mill roll-gap.
In the steel rolling field, hydraulic pressure is depressed milling train and is had rolling time control roll gap precision height, advantages such as the good product quality of production.But, the employed hydraulic mill of each manufacturer at present, because of the position mode difference that each displacement transducer is installed, the rolling accuracy error of each hydraulic mill that it brings is bigger, directly has influence on the quality of product.In the prior art, the displacement transducer mounting means of various hydraulic mills and structure mainly contain on the outer sidewall of following two kinds of a kind of depress oil cylinders that are mounted in hydraulic mill, the errors in position measurement that tilts and to be produced for fear of hydraulic cylinder piston, so on 180 ° diagonal positions, should symmetry be installed by two displacement transducers, with the value of mean value as feedback.The shortcoming of this mounting means has (1) poor working environment, and the one, in hot-rolling mill, be subject to thermal-radiating influence, the certainty of measurement of sensor is reduced.The 2nd, when conduct pressed the formula hydraulic cylinder, hydraulic cylinder placed the bottom of framework window, and sensor is vulnerable to the splash of technology lubricant and influences its operate as normal.(2) another is mounted in the inside of hydraulic jack.The structure of this device is that displacement transducer is positioned between the piston and cylinder base of depress oil cylinder inside, and on the axis of oil cylinder.In this device, displacement transducer is to be put in fully in the oil cylinder, though only need a sensor, but dismounting maintenance sensor must disintegrate oil cylinder, very inconvenience, and influencing service life of oil cylinder, this its major defect of device at the inner sensor installation of oil cylinder has (1) mounting or dismounting sensor oil cylinder must be pulled down from the milling train window.(2) the mounting or dismounting sensor must break away from hydraulic system with oil cylinder, with oily emptying in the oil cylinder, therefore destroys the seal of hydraulic system easily, and air is entered in the hydraulic system, influences the operate as normal of system.(3) sensor is tuning very inconvenient.
The purpose of this utility model is that proposition is a kind of simple in structure, installation, debugging and easy to maintenance, and the hydraulic mill that control accuracy is high is depressed checkout gear.
According to the purpose of this utility model, the hydraulic mill that we proposed is depressed the operation principle of checkout gear, it is piston item termination one link rod in hydraulic jack, the other end of link rod and the iron core of displacement transducer link, and displacement transducer is to be coupled to cylinder body by parts such as link rod, displacement transducer iron core bar and sleeves to install outward.When hydraulic mill in working order the time, piston in the depress oil cylinder of hydraulic mill, relatively the displacement of cylinder body is to be identical with the displacement that is driven the displacement transducer iron core by link rod, therefore to be sent to the displacement signal of console be the displacement of the relative cylinder body of hydraulic pressure depress oil cylinder inner carrier to displacement transducer, and just the hydraulic mill roll depresses value.According to above-mentioned principle, the concrete structure that the hydraulic mill that we proposed is depressed checkout gear can be described in detail with reference to the accompanying drawings, and this accompanying drawing is the structural representation that the utility model hydraulic mill is depressed checkout gear.1 is displacement transducer in the accompanying drawings, and 2 is trip bolt, and 3 is tuning cover, and 4 is locking nut, and 5 is sleeve, and 6 is link rod, and 7 is sleeve flange, and 8 is cylinder body, and 9 is piston.The composition that the utility model hydraulic mill is depressed checkout gear is in the outside of this rolling mill hydraulic oil cylinder housing displacement transducer 1 to be housed, the top that it is characterized in that oil cylinder inner carrier 9 is equipped with and is extended the external link rod of cylinder shell 6, sleeve flange 7 is equipped with at central axis place at oil cylinder top cylinder body 8, sleeve 5 is housed on sleeve flange 7, at sleeve 5 internal upper parts tuning cover 3 is housed, on tuning cover 3, trip bolt 2 is housed, in tuning cover 3, displacement sensor 1 is housed, locking nut 4 is housed at the outer wall of tuning cover 3.The iron core of displacement transducer 1 should join with link rod 6 tops.Another feature of the utility model device be displacement transducer 1 with link rod 6 tops scoop out mutually with piston 9 on same central axis.The utility model checkout gear is boring and installing sleeve flange 7 and an oil seal circle outside the depress oil cylinder cylinder body 8 of existing hydraulic mill, one end of link rod 6 firmly connects with the top of piston 9, wherein an end stretches out cylinder body 8 outer backs and firmly connects with the iron core of displacement transducer 1, one end of sleeve 5 should firmly connect with sleeve flange 7, and tuning cover 3 and displacement transducer 1 are installed in the other end, after adjusting the position of displacement transducer 1 according to designer's requirement simultaneously, tighten trip bolt 2 and locking nut 4, the output signal line with displacement transducer 1 is connected to console again.
Adopt the utility model hydraulic mill to depress checkout gear and have the control accuracy of detection height compared with prior art, displacement transducer work is not subjected to extraneous interference, installation, debugging and maintenance and repair are convenient, the Yin Ben device is reasonable in design, only need a sensor is installed, so electrical circuit is also simple and characteristics such as reliability height.

Claims (2)

1, a kind of hydraulic mill is depressed checkout gear, composition is in the outside of this rolling mill hydraulic oil cylinder housing displacement transducer to be housed, the top that it is characterized in that oil cylinder inner carrier 9 is equipped with and is extended the external link rod of cylinder shell 6, sleeve flange 7 is equipped with at central axis place at oil cylinder top cylinder body 8, sleeve 5 is housed on sleeve flange 7, at sleeve 5 internal upper parts tuning cover 3 is housed, on tuning cover 3, trip bolt 2 is housed, in tuning cover 3, displacement transducer 1 is housed, outer wall at tuning cover 3 is equipped with locking nut 4, and the iron core of displacement transducer 1 should link with link rod 6 tops.
