Description
Technical field
The utility model relates to the vacuum melting chamber of vacuum melting furnace, the air pressure device for securing door device of a kind of door for vacuum chamber especially.
Background technology
Vacuum smelting fast solidification stove is under vacuum or protective atmosphere, through eddy-current heating metal or alloy is melted, and through with water-cooled copper rod metal or alloy being cooled off fast, forms specific crystal or non crystalline structure material then.The device for securing door of existing vacuum induction melting rapid hardening spun furnace is mechanical, and concrete structure is; On the tank wall of vacuum chamber, have one can be movable leading screw, a supporting with it handwheel is arranged on the leading screw, a block plate is arranged on the fire door of vacuum chamber; The fluting bigger slightly than leading screw diameter arranged on the steel plate, and leading screw can enter in the fluting, and handwheel can be pushed down steel plate; Close fire door, be put into leading screw in the fluting of the steel plate on the fire door, rotate handwheel; Can overwhelm fire door closely on the tank wall of vacuum chamber; Make vacuum chamber become closed structure, can form the vacuum metling environment to vacuumizing in the vacuum chamber like this by open architecture.Because such device for securing door structure causes, manual tight door effort is changed after vacuumizing and need be unclamped device for securing door, unclamps the device for securing door blast oven door opening that prevents to meet accident in the stove and hurts sb.'s feelings the shortcoming of complicated operation.In view of above-mentioned many reasons, need to improve the locking device of vacuum smelting fast solidification stove door for vacuum chamber.
The utility model content
There is leakage phenomenon in the utility model for expansion, the vaporization of the fluid that solves hydraulic system after being heated, and makes to carry out oil cylinder and can't drive; Cisco unity malfunction through rational design, provides a kind of air pressure device for securing door device of door for vacuum chamber; Pneumatic keying Vacuum door device for securing door; Stove implode fire door cylinder buffering reduces labour intensity, has guaranteed safety of workers.
The utility model is in order to realize above-mentioned goal of the invention; Adopt following technical scheme: a kind of air pressure device for securing door device of door for vacuum chamber; Be to constitute by, vacuum melting furnace casing, oven door sealing circle, fire door rotating shaft, fire door, device for securing door head clamp, handle, cylinder, cylinder tailstock; The furnace wall end preformed groove of vacuum melting furnace casing fire door is provided with the oven door sealing circle in the groove, the furnace wall arranged outside fire door rotating shaft fastening devices of fire door one side, and the opposite side of fire door furnace wall is provided with the cylinder gripping mechanism; Fire door arranged outside fire door, fire door one side are provided with the corresponding fire door rotating shaft of coupling spindle, and the outer end of fire door opposite side is provided with the device for securing door head clamp, and device for securing door head clamp middle part is provided with hole clipping; The furnace wall arranged outside cylinder of fire door opposite side, cylinder bottom is provided with cylinder tail junction plate, cylinder tail junction plate preformed hole; The outside, furnace wall respective cylinder tail junction plate is provided with the cylinder tailstock; The preformed hole of cylinder tailstock preformed hole respective cylinder tail junction plate is provided with the spiral shell axle in the hole, piston and piston rod are set in the cylinder; The piston rod outer end is provided with handle, the hole clipping setting of the corresponding device for securing door head clamp of the piston rod of cylinder.
Beneficial effect: appropriate design, pneumatic keying Vacuum door device for securing door, stove implode fire door cylinder buffering reduces labour intensity, has guaranteed safety of workers.
Compared with prior art, the invention has the advantages that: do power source with cylinder, alleviated the labour intensity that the workman fastens the vacuum melting furnace door; The explosion accident that in the vacuum smelting furnace, meets accident is that cylinder has a cushioning effect to the fierce unlatching of fire door, prevents the generation of secondary injury, the safety of protection personnel and equipment.
The safety type device for securing door that this use is novel, the cylinder tailstock that cylinder is connected with the vacuum melting furnace cabinet exterior; The handle that is connected with its cylinder rod; The device for securing door head clamp of the fluting that is connected with the vacuum melting furnace door.Hinged between cylinder tailstock and the cylinder, can rotate.Fluting in the middle of the device for securing door head clamp is wideer than cylinder rod, and corresponding with the cylinder rod position, and cylinder rod can enter in the fluting of device for securing door head clamp.The cross section of handle is wideer than the fluting on the device for securing door head clamp, and cylinder rod gets in the device for securing door fluting, and handle can not deviate from the fluting on the device for securing door head clamp.At closing time, cylinder rod stretches out, and moves the vacuum melting furnace door in the travel range that cylinder rod stretches out to; Rotation cylinder; Let cylinder rod enter in the fluting on the device for securing door head clamp, cylinder rod is regained, and the vacuum melting furnace door tightly is pressed in the sealing of vacuum melting furnace casing; At this moment the vacuum unit begins to bleed, and accomplishes tight door process.Explosion time meets accident in vacuum smelting furnace casing; Pressure in the vacuum melting furnace casing is suddenly greater than atmospheric pressure; Make fire door produce huge outside thrust; Impact force when at this moment the gas of cylinder can throw open the vacuum melting furnace door cushions, and minimizing vacuum melting furnace door throws open near personnel or equipment are caused the secondary injury, and the secondary injury when avoiding this type accident to take place takes place.
