Abstract
The utility model relates to an electrode clamp oil cylinder of an electric furnace. Conventional various electrode clamp oil cylinders of electric furnaces have defects that sealing rings and pistons are liable to wear or electrode clamping strokes cannot reach requirements. The electrode clamp oil cylinder is provided with a piston oil cylinder composed of a cylinder body, pistons and a piston rod, wherein the piston and the piston rod are arranged inside the cylinder body. A disk spring sleeves the piston rod. One end of the piston oil cylinder is equipped with an end cap, and the other end of the piston oil cylinder is in connection with adjusting flanges and a connector via the piston rod. The end cap is equipped with an oil inlet hole and an oil return hole. Sealing rings are circumferentially disposed on a contact surface between the pistons and the cylinder body. A sealing gasket is arranged between the two adjusting flanges, and locking nuts are disposed at two ends of each adjusting flange. According to the utility model, a requirement that the stroke of the electrode clamp oil cylinder of an electric furnace is adjustable is met, and two pistons and two sealing rings are adopted to enable the pistons and the oil cylinder to be prolonged in service life. The electrode clamp oil cylinder has a concise structure, enables the sealing rings to be conveniently replaced, is low in accident rate and high in reliability, and is suitable for various electric furnace electrode clamp mechanisms.
Description
Technical field
the utility model relates to a kind of metallurgical equipment, is specifically related to a kind of electric furnace electrode and folds up oil cylinder.
Background technique
At present both at home and abroad the electrode holder of the steel-smelting electric furnace cylinder of draining the oil mainly contains following two kinds of modes: 1, electric furnace → electrode holder cylinder → mono-piston of draining the oil, single sealing; 2, drain the oil cylinder → without controlling device of electric furnace → electrode holder.The 1st kind of form, the electrode holder cylinder of draining the oil adopts single piston, and piston and piston rod are weldingly connected, and piston plays sealing case guiding double action, and in use, piston and seal ring easily wear and tear, thereby cause oil cylinder leakage of oil, and impact is used; The 2nd kind of form, the electrode holder cylinder piston rod of draining the oil is directly connected by bearing pin with electrode anchor ear, there is no adjustment stroke mechanism, owing to there being the difference of manufacturing and fixing error and dish spring force, the stroke that does not often reach in use design requires or electrode to step up power little, electrode glides, and causes the accident.
At present the electric furnace electrode of various types fold up oil cylinder exist seal ring and piston easily wearing and tearing or electrode step up stroke and do not reach the defect of requirement, parts replacement rate is high, changes inconveniently, causes operating cost to strengthen.
Summary of the invention
The purpose of this utility model is to provide a kind of electric furnace electrode and folds up oil cylinder, meets electrode in electric furnace installation, parts replacement and smelting process and loosens formation adjusting, thereby change electrode clamping force, and electrode is held tightly, reduces accident rate.
The technological scheme that the utility model adopts is:
A kind of electric furnace electrode folds up oil cylinder, it is characterized in that:
Be provided with the piston oil-cylinder being made up of the piston arranging in cylinder body and cylinder body and piston rod, upper cover of piston rod is provided with dish spring;
Piston oil-cylinder one end is provided with end cap, and the other end is connected with and is reconciled flange and connecting body by piston rod.
Described end cap is provided with oil inlet hole and spill port.
Described piston is being provided with seal ring with the surface of contact pressed on ring week of cylinder body.
Described regulating flange is provided with two, between be provided with sealing gasket, two ends are provided with locking nut.
The utlity model has following advantage:
The utility model electrode holder cylinder of draining the oil meets electric furnace for the drain the oil adjustable requirement of stroke of cylinder of electrode holder; Meanwhile, adopt double-piston and Double seal ring, make piston and oil cylinder life, simple for structure, use and change seal ring conveniently, accident rate is low, and reliability is high, is applicable to various electric furnace electrodes and folds up mechanism.
Accompanying drawing explanation
Fig. 1 is the utility model sectional structure chart.
Fig. 2 is the utility model end cover structure figure.
In figure, 1-end cap, seal ring of 2-, No. bis-seal rings of 3-, 4-piston, 5-cylinder body, 6-dish spring, 7-piston rod, 8-regulating flange, 9-sealing gasket, 10-locking nut, 11-connecting body.
Embodiment
