Abstract
The invention relates to a crystallizer hydraulic cylinder pneumatic locking mechanism. The crystallizer hydraulic cylinder pneumatic locking mechanism comprises a case body, an air inlet, a reversing valve, a piston, a pressing sleeve, an opening locking sleeve, an air outlet and a disc spring, wherein the air inlet is arranged at one end of the case body and the air outlet is arranged at the other end of the case body. The reversing valve is connected with the outer end of the air inlet and the piston, the pressing sleeve and the disc spring is sequentially arranged inside the case body from the air inlet. A coned surface of the pressing sleeve contacts with the opening locking sleeve and the opening locking sleeve contacts with the piston of the hydraulic cylinder. Compared with the prior art, the crystallizer hydraulic cylinder pneumatic locking mechanism has the advantages of being simple in structure, convenient to install, high in control accuracy, practical and scientific. Accordingly, the position of a copper plate of the crystallizer can be controlled under the condition of choosing a proper tight locking force, namely the taper of the crystallizer can be controlled to avoid the situation of 'out-of-control cone' caused by leakages of hydraulic pipelines, faults of hydraulic block and leakages of hydraulic cylinder.

Background technique
In order to meet the hot rolling technology requirement wide to different casting blank, continuous cast mold is provided with leptoprosopy width-modulated device.Meanwhile, in order to reduce online shutdown cold conditions, adjust the wide time to improve the operating rate of casting machine, generally take to adjust strand width (being that online hot tune is wide) in casting process.
Crystallizer adjusts the wide kind of drive generally to adopt the modes such as assemblying body of trapezoidal screw nut, planetary ball leading screw, worm and gear and ball screw, and wherein trapezoidal screw nut is adjusted wide technology: have auto-lock function, but have mechanical clearance; Planetary ball leading screw: mechanism self is without auto-lock function; The assemblying body of worm and gear and ball screw: have auto-lock function, but mechanism is complicated; Oil hydraulic cylinder is adjusted wide: magnetic scale mechanism Linear transmission, without reciprocal integrating error, accurate positioning, but machinery-free lock function, " running cone " phenomenon easily occurs in production process.
Summary of the invention
The object of this invention is to provide a kind of crystallizer hydraulic cylinder pneuma-lock mechanism and using method thereof.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of crystallizer hydraulic cylinder pneuma-lock mechanism, comprise housing, suction port, selector valve, piston, gland, opening lock sleeve, relief opening and dish spring, described housing one end is provided with suction port, the other end is provided with relief opening, the outer end of suction port is connected with selector valve, from suction port end, start enclosure interior and be provided with successively piston, gland and dish spring, the gland conical surface contacts with the opening lock sleeve on housing, and opening lock sleeve contacts with hydraulic cylinder piston rod.
A using method for crystallizer hydraulic cylinder pneuma-lock mechanism, comprises the following steps:
1) on the piston rod of adjusting wide oil hydraulic cylinder, locking mechanism is installed, suction port is connected with air pump by selector valve;
2) adjust when wide and first hydraulic cylinder piston rod is carried out to " release ", 3 seconds of time delay, when suction port passes into pressed gas, pressurized gas promote piston and move, and piston promotes gland again and moves, dish spring is compressed simultaneously, dish spring chamber gas is discharged by relief opening, and gland is applied to the pressure that opening locking puts and is disengaged, and the power of the tight hydraulic cylinder piston rod of opening locking cartridge clip is also removed thereupon, at this moment piston rod is in " release " state, and then realizes the change of casting blank section;
3) when reaching setting value, adjustment is introduced into " locking " state, 3 seconds of time delay, when selector valve is during in unloading condition, gland moves under the effect of dish spring, by the gland conical surface, tightly opening being locked to casing pressure is tightly adjusting on the piston rod of wide oil hydraulic cylinder, at this moment piston rod is in " locking " state, and then realizes hydraulic cylinder piston rod and remain on desired location.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of crystallizer hydraulic cylinder pneuma-lock mechanism and using method thereof, there is the features such as simple in structure, easy for installation, control accuracy is high, science is practical, in coupling mechanism force, select suitable in the situation that, crystallizer copper Board position is controlled, the tapering that is crystallizer is controlled, has avoided because hydraulic pipe line leakage, hydraulic valve bank fault, oil hydraulic cylinder leakage etc. are former thereby cause the generation of " run about cone " phenomenon.
