Abstract
The utility model discloses a lifting sealing device for an annealing furnace, which comprises a cylinder, a box body, a lifting rod, a lifting frame and a door plate, wherein the cylinder is arranged on the box body, the lower end of the cylinder is connected with the lifting rod which penetrates through the box body, the lower end of the lifting rod is connected with the lifting frame which is connected with one end of the connection piece in hinge mode, the other end of the connection piece is hinged with the door plate, and a rubber ring for sealing is arranged on the door plate. The lifting sealing device for the annealing furnace adopts the cylinder to drive ascending and descending of a sealing door and is simple in structure. The sealing door is hinged with the lifting frame which drives the sealing door to move downwards. When the sealing door moves to the bottom, door closing is achieved, the lifting frame moves downwards continuously, and the sealing door is led to move transversely through a hinge to achieve sealing, so that door closing and sealing actions are consistent. The sealing ring adopts heat resisting rubber, thereby being good in sealing effect.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of annealing furnace and uses the rise-fall type seal arrangement.
Background technique
All need carry out annealing in process in many component production processes in the present mechanical industry; Annealing is meant metal slowly is heated to uniform temperature; Keep the enough time, with the Reasonable Speed cooling, annealing must be carried out in special atmosphere furnace then; Accomplish heating, manufacturing processs such as cold, isothermal, slow cooling soon, thereby obtain the metal structure of high-quality.
Feeding and discharging need be set before and after the annealing furnace in process of production and use the vacuum air-changing chamber, send the labor and materials that need annealing in process to the vacuum air-changing chamber after, necessary quick closedown and sealed vacuum air-exchanging chamber vacuumize then, charge into shielding gas again, sealing is a key technology.In the prior art, closing the door and sealing of large-scale vacuum air-exchanging chamber is that substep is realized, make integral sealing means complicated, and motor reaction is slow, and sealing effect is not good enough.
The model utility content
The purpose of the utility model is to provide a kind of annealing furnace to use the rise-fall type seal arrangement, and it has simple in structure, closes the door, seals action and link up advantage of good sealing effect.
The purpose of the utility model is to realize through following technological scheme:
A kind of annealing furnace is used the rise-fall type seal arrangement, and it comprises cylinder, casing, lifting arm, pulling yoke and door-plate, and said cylinder is placed on the casing; The lower end connects lifting arm; Said lifting arm passes casing, and the lower end connects pulling yoke, and said pulling yoke is connected with link one end; The said link the other end and door-plate are hinged, and said door-plate is provided with sealing and uses rubber ring.
Said lifting arm is connected with pulling yoke through bolt or pin key.
Said sealing uses the rubber ring material to be heat resistant rubber.
The beneficial effect of the utility model is that said annealing furnace is with the up-down of rise-fall type seal arrangement employing cylinder drive sealed door, and is simple in structure; Sealed door and pulling yoke are hinged, and pulling yoke drives sealed door and moves downward, and when sealed door moves to the bottom, have realized closing the door, and pulling yoke continues to move downward, and make the sealed door transverse movement realize sealing through hinge, close the door, seal action and link up; Seal ring adopts heat resistant rubber, good sealing effect.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of this practical annealing furnace with rise-fall type seal arrangement list sealed door;
The structural representation that Fig. 2 seals up a door with rise-fall type seal arrangement double density for this practical annealing furnace.
Among the figure:
1, cylinder, 2, casing, 3, lifting arm, 4, pulling yoke, 5, door-plate, 6, link, 7, rubber ring, 8, doorframe, 9, the vacuum air-changing chamber, 10, supporting frame.
Embodiment
As shown in Figure 1, in present embodiment, said annealing furnace comprises cylinder 1, casing 2, lifting arm 3, pulling yoke 4 and door-plate 5 with the rise-fall type seal arrangement; Said cylinder 1 is placed on the casing 2, and the lower end connects lifting arm 3, and said lifting arm 3 passes casing 2; The lower end connects pulling yoke 4; Said pulling yoke 4 is connected with link 6 one ends, and said link 6 the other ends and door-plate 5 are hinged, and said door-plate 5 is provided with sealing with rubber ring 7.
At closing time; Cylinder 1 promotes lifting arm 3, pulling yoke 4 and door-plate 5 and moves downward together, when door-plate 5 moves to supporting frame 10 upper ends, accomplishes the action of closing the door of vacuum air-changing chamber 9; Cylinder 1 continues to promote lifting arm 3 and moves downward with pulling yoke 4; Door-plate 5 is realized transverse movements through the link 6 that is hinged, and is adjacent to the doorframe 8 of vacuum air-changing chamber 9, realizes the sealing action.
When opening the door; Cylinder 1 pulling lifting arm 3, pulling yoke 4 move upward together, and door-plate 5 is realized transverse movement through the link 6 that is hinged, with doorframe 8 disengagings of vacuum air-changing chamber 9; Depressurization; Cylinder 1 continues pulling lifting arm 3, pulling yoke 4 and door-plate 5 and moves upward together, accomplishes the action of opening the door of vacuum air-changing chamber 9, and pulling yoke 4 and door-plate 5 are taken in the casings 2.
As shown in Figure 2, in present embodiment, be to install a door-plate 5 additional at pulling yoke 4 opposite sides, door-plate 5 also is to be hinged on pulling yoke 4 through link 6, under cylinder 1 drives, realizes both sides switch door and sealing action simultaneously.
Said annealing furnace has simple in structure with the rise-fall type seal arrangement, close the door, seal action and link up advantage of good sealing effect.
