Description

Technical Field

[0001] The invention relates to the field of a furnace cover belt horizontally pressing soft sealing device, in particular to a heat treatment furnace cover belt horizontally pressing soft sealing device. Background Art

[0002] During the heat treatment process, the uniformity of furnace temperature is the most important factor affecting product quality and performance, and the important factor affecting the uniformity of furnace temperature is the sealing of the furnace chamber, that is, it is not affected by the external temperature and humidity. The existing heat treatment trolley furnace and box-type furnace cover sealing device are vertical up and down structures, and the movement trajectory of the furnace cover is a straight line. There is friction and wear between the furnace cover and the furnace panel. The steel structure of the furnace cover and the steel structure of the furnace panel are directly in contact and sealed.

[0003] According to the published patent 201520514919.2, the furnace cover of the heat treatment trolley furnace has a horizontal compression soft sealing device, which is realized by a composite motion track and a soft sealing structure. The furnace cover is rotated to a certain angle and then moves up and down to create conditions for realizing a soft sealing structure between the furnace cover and the furnace panel. The sealing pair between the furnace cover and the furnace panel is changed from a hard sealing structure to a soft sealing structure. When the furnace cover is at the lower end, the furnace cover has a continuous horizontal thrust, so that the furnace cover and the furnace panel are compressed and sealed through the soft sealing structure, and a convex structure is designed on the inner plane of the furnace cover, so that the furnace cover is effectively embedded in the furnace chamber, so that the furnace gas cannot leak in a straight line, and a labyrinth seal is realized.

[0004] However, in traditional heat treatment processes, the furnace cover design used in heat treatment furnaces is usually equipped with a compressed soft sealing device. However, after the furnace cover is opened and closed, additional special equipment is still required to place and remove the workpiece, which undoubtedly increases the complexity of the operation process. More importantly, the soft sealing method currently used mainly relies on the direct contact between the sealing material and the surface of the furnace body to achieve the sealing effect. However, the surface of the furnace body often has a certain degree of unevenness, and it is difficult to ensure that the soft sealing material can fit completely and tightly on the surface of the furnace body, thereby weakening the sealing efficiency of the soft seal to a certain extent. For this reason, it is necessary to design a new technical solution to solve this problem. Summary of the invention

However, after the furnace cover completes the opening and closing action, it is still necessary to additionally configure special equipment to place and remove the workpiece, which undoubtedly increases the complexity of the operation process. More importantly, the soft sealing method currently used mainly relies on the direct contact between the sealing material and the surface of the furnace body to achieve the sealing effect. However, the surface of the furnace body often has a certain degree of unevenness, and it is difficult to ensure that the soft sealing material can fit completely and tightly on the surface of the furnace body, thereby weakening the technical problem of the sealing efficiency of the soft seal to a certain extent.

During the heat treatment process, the first drive motor 3 can be turned on, and the first drive motor 3 will drive the first motor shaft 301, and the first motor shaft 301 will drive the mesh tube 302 and multiple workpieces to rotate, so that multiple workpieces at different positions are rotationally exposed to the heat inside the furnace body 1, thereby achieving uniform heat treatment of workpieces at different positions. After the heat treatment of the workpieces is completed, the dual-axis motor 2 can be started to rotate in the opposite direction, so that the threaded rod 201 is used to drive the moving block 202 and the moving plate 206 to move in opposite directions, driving the furnace cover body 207 and the mesh tube 302 to move directly out of the furnace body 1, so that the staff can directly take the workpieces in the mesh tube 302, which solves the problem that in the current traditional heat treatment process, the furnace cover design used in the heat treatment furnace is usually equipped with a compressed soft sealing device. However, after the furnace cover completes the opening and closing action, additional special equipment is still required to place and remove the workpiece, which undoubtedly increases the technical issues of the complexity of the operation process.

The frame-shaped soft-sealed airbag 404 is engaged in the frame-shaped grooves 403 opened at the front and rear ends of the furnace body 1. When the furnace cover body 207 moves to fit and seal the two ends of the furnace body 1, the air pump 401 can be opened, and the air pump 401 will draw external gas into the frame-shaped soft-sealed airbag 404. , so that the frame-shaped soft sealing airbag 404 expands rapidly, so that the expanded frame-shaped soft sealing airbag 404 fits the uneven surface of the furnace body 1, and frame-shaped grooves 403 are provided at both ends of the furnace body 1, and the frame-shaped soft sealing airbag 404 can be inserted into the frame-shaped grooves 403 on the surface of the furnace body 1, so as to achieve the clamping and sealing of the frame-shaped soft sealing airbag 404, further improve the sealing effect, and solve the technical problem that the currently used soft sealing method mainly relies on the direct contact between the sealing material and the surface of the furnace body 1 to achieve the sealing effect. However, the surface of the furnace body 1 often has a certain degree of unevenness, and it is difficult to ensure that the soft sealing material can fit completely and tightly on the surface of the furnace body 1, thereby weakening the sealing efficiency of the soft seal to a certain extent.

[0033] It is worth noting that see Figure 4A mounting groove 208 is provided at the bottom of the furnace cover main body 207, and a second driving motor 209 is installed at the top of the mounting groove 208.
