Description
Technical field
The utility model relates to oven door sealing technical field, especially a kind of furnace door sealing device of tumbling.
Background technology
It is the link of the aluminium processing industry energy and material consumption maximum that aluminium processing melting is produced, and the basic demand of fire door sealing is had to two: the one, and fire door rigidity will be got well, the deflection while reducing to be heated, the 2nd, oven door sealing will be got well.The furnace temperature of stove of tumbling is very high, making oven door sealing and compression is a very stubborn problem, existing fire door hold-down mechanism has several modes below: 1. inclined-plane hold-down mechanism, it is the modal sealing mechanism of fire door that the component that the deadweight that utilizes fire door produces by 1.5 ° of-3 ° of inclined-planes compresses firedoor frame, the advantage of this mechanism is simple for structure and cheap, but the shortcoming of this structure is poorly sealed close, easy artillery fire, firedoor frame and fire door frame easily burn out, the localized burn of fire door and fire door frame, can cause more serious runout again, thereby formation vicious circle, simultaneously, greatly reduce the service life of fire door, 2. cylinder pressing mechanism, but in use usually fire door under the state of high temperature, move a half, cylinder lost efficacy and leaked gas because of sealing, force because of condition of high temperature servant cannot be near processing in time blowing out, 3. spring compression mechanism, is not suitable for high temperature furnace and adopts, and the key of design is according to fire door size and weight, to determine the thrust of fire door, rationally after the parameter of definite spring after a time, spring can be affected, and has reduced the thrust of fire door.This is the existing weak point of prior art.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the utility model provides a kind of furnace door sealing device of tumbling, and this furnace door sealing device is simple in structure, good sealing effect, and oven door sealing automation, reduces labor strength.
The utility model solves the technical scheme that its technical problem adopts: a kind of furnace door sealing device of tumbling, it comprises fire door, rotating shaft, the axis of guide, hydraulic cylinder and pedestal, described hydraulic cylinder is fixed on pedestal, on described rotating shaft, be fixedly connected with crossbeam groove, the expansion link of described hydraulic cylinder and crossbeam groove are hinged, between described rotating shaft and the axis of guide, be fixedly connected with crossbeam arm, the edge of described fire door is provided with groove, and the described axis of guide is embedded in the groove at fire door edge.
Above-mentioned rotating shaft, the axis of guide, hydraulic cylinder and pedestal are respectively arranged with two, and are symmetrically distributed in the both sides of fire door.Such design can make that fire door both sides are stressed to be balanced, and strengthens the effect of sealing, improves the service life of fire door.
Above-mentioned rotating shaft is parallel with the axis of guide.
Above-mentioned crossbeam arm is provided with a plurality of, and is uniformly distributed, and has strengthened the bonding strength between rotating shaft and the axis of guide.
The beneficial effects of the utility model are: this furnace door sealing device is simple in structure, and sealing is tight, and fire door both sides are stressed can be balanced, and oven door sealing automation reduces labor strength, has reduced potential safety hazard, has improved operating efficiency.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
