Abstract
The invention discloses a vacuum sealing device capable of utilizing atmospheric negative pressure. The surface hinge is welded on the cover plate. The cover plate is arranged above the platform bottom plate; therefore, the cover plate can move through the hinge, and the use is convenient in the operation process.
Description
Technical Field
The invention belongs to the field of heat treatment furnaces in the steel-making industry, and further relates to a vacuum sealing device capable of utilizing atmospheric negative pressure.
Background
In the steel industry, it is sometimes desirable to flatten sheet materials, particularly titanium alloy sheet materials, to minimize widthwise irregularities and improve the flatness of the sheet material. The industry generally processes the materials by using a vacuum creep finishing furnace, and the structure of the furnace body is shown as figure 1. The working principle of the vacuum creep flattening furnace is that a heating element heats a plate, a flexible material is fully paved on the plate, a nylon film covers the flexible material, then the hearth is vacuumized, so that atmospheric pressure acts on the flexible material through a plastic film, the flexible material applies uniform pressure to the plate, the plate is pressed and heated to generate creep deformation gradually, and the flatness of the surface of the plate is improved.
At present, the sealing structure of the vacuum creeping leveling furnace adopts a mode that the periphery of a nylon film (four edges of the leveling furnace) is directly covered with a metal cover plate and locked for sealing, the sealing effect of the sealing structure is poor, air leakage is easy to occur, and therefore the vacuum negative pressure is insufficient and the expected leveling effect cannot be achieved.
Disclosure of Invention
The invention adopts the technical scheme to solve the technical problems that a vacuum sealing device capable of utilizing atmospheric negative pressure is provided, wherein the specific technical scheme is as follows:
a platform bottom plate 6 is arranged above the hearth furnace wall 1, a bottom hinge 2 is welded on the side face of the platform bottom plate 6, the bottom hinge 2 is connected with a double-hinge plate 4 through round steel 3, and the double-hinge plate 4 is connected with a surface hinge 5 through round steel. The face hinge 5 is welded to the cover plate 8. The cover plate 8 is above the platform bottom plate 6; the cover plate 8 can move through a hinge, and 2 semicircular grooves are machined on two surfaces of the cover plate 8, which are in contact with the platform bottom plate 6. The flexible material 9 is padded below the nylon film 10, the edge part of the nylon film 10 is embedded into the 2 grooves of the bottom plate 6 and then embedded by the circular rubber strip 7, the upper part of the circular rubber strip 7 is covered by the movable steel cover plate 6, and the upper part of the cover plate 6 is clamped by a Z-shaped clamp.
Compared with the prior art, the invention has the following beneficial effects: the sealing device has the main advantages that the sealing device is simple in structure and convenient to use, and can utilize the atmospheric negative pressure.

Detailed Description
The invention is further described below with reference to the figures and examples.
Even if the cover plates on the periphery of the existing sealing structure are tightly pressed, gaps still exist between the films and the platforms, and the sealing effect is poor, so that air leakage is easy, and the vacuum negative pressure is insufficient, and the expected leveling effect cannot be achieved. The invention provides a vacuum sealing device capable of utilizing atmospheric negative pressure, which is simple in structure and convenient to use, and can utilize the atmospheric negative pressure by processing 2 semicircular grooves on a platform around a furnace body, embedding the edge part of a flexible material 9 into the grooves, then embedding a circular rubber strip 7 into the grooves, covering the upper surface of the circular rubber strip 7 with a movable steel cover plate 6, and after a furnace chamber begins to be vacuumized, a nylon film 10 can be in close contact with the platform.
Referring to the attached drawings, a platform bottom plate 6 is arranged above a hearth furnace wall 1, bottom hinges 2 are welded on the side faces of the platform bottom plate 6, the bottom hinges 2 are connected with double hinge plates 4 through round steel 3, and the double hinge plates 4 are connected with surface hinges 5 through round steel. The face hinge 5 is welded to the cover plate 8. The cover plate 8 is above the platform bottom plate 6; therefore, the cover plate 8 can move through the hinge, and the use is convenient in the operation process. And 2 semicircular grooves are machined on two surfaces of the cover plate 8, which are contacted with the platform bottom plate 6. In order to utilize the atmospheric negative pressure, a flexible material 9 is padded below a nylon film 10, the edge part of the nylon film 10 is embedded into 2 grooves of a bottom plate 6 and then embedded by a round rubber strip 7, a movable steel cover plate 6 is covered above the round rubber strip 7, and a Z-shaped clamp is used for clamping the cover plate 6. Therefore, after the furnace chamber is vacuumized, the nylon film can be in close contact with the platform, and the furnace chamber can effectively utilize atmospheric negative pressure.
Although the present invention has been described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
