Description

Technical Field

[0001] The utility model belongs to the technical field of tempering furnaces, and particularly relates to a furnace body movable cover mechanism and a high-temperature tempering furnace. Background Art

[0002] The workpiece must be tempered after quenching with quenching oil. The tempering furnace is used for tempering general metal parts in air and for quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, and aluminum plates.

[0003] At present, in order to maintain the temperature in the tempering furnace, an insulation cover is needed to seal the tempering furnace. In the prior art, a crane and a lifting rope are usually used to move the insulation cover. Therefore, during the movement, the insulation cover lifted by the lifting rope will shake due to inertia. When the insulation cover needs to be installed, the user needs to use tools or manually support the insulation cover so that the insulation cover can smoothly cover the furnace body, which is inconvenient to use.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background technology of the technology described in this article. Therefore, the background technology may contain certain information that does not form the prior art known in this country to those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a furnace body moving cover mechanism and a high-temperature tempering furnace, the purpose of which is that, through the use of a translation assembly and a lifting arm, when the insulation cover needs to be opened, the lifting arm can lift the insulation cover, and then the rotating roller rotates counterclockwise to drive the translation frame and the insulation cover to move, so that the insulation cover can be away from the heating chamber. When installing the insulation cover, the rotating roller rotates clockwise, so that the translation frame drives the insulation cover to move above the heating chamber again, and then the lifting arm pushes the insulation cover down to close with the heating chamber. This method is more stable than the traditional rope crane movement, improves the connection rigidity, reduces the shaking during movement, and enhances the stability and accuracy of disassembly and assembly.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A furnace body movable cover mechanism, comprising a heat-insulating cover;

[0008] A translation assembly, used for horizontally moving the thermal insulation cover, comprising a translation frame arranged parallel to and above the thermal insulation cover, and a slide groove opened on the ground, wherein the translation frame includes legs perpendicular to the ground;

[0009] A lifting arm is provided between the thermal insulation cover and the translation frame, and is used for lifting or lowering the thermal insulation cover;

[0010] A slide rail is provided in the slide groove, and a clamping block movably connected to the slide rail is provided at the frame foot of the translation frame. Rotating rollers that fit the ground are also provided on both sides of the clamping block, and the rotating rollers are perpendicular to the extension direction of the slide groove.

[0011] As a preferred technical solution, limiting grooves are provided on both sides of the slide rail, and a clamping block is provided on the inner wall of the clamping block, wherein the clamping block is movably clamped in the limiting groove.

[0012] Furthermore, a pulley is provided on the side of the clamping block facing the inner wall of the limiting groove.

[0013] Furthermore, a plurality of protrusions are provided on the roller body of the rotating roller.

[0014] A high-temperature tempering furnace includes a furnace body embedded in the ground and a furnace body movable cover mechanism. The furnace body includes a heating chamber for heating workpieces. The slide grooves are arranged parallel to the ground on both sides of the heating chamber opening, and the insulation cover is arranged parallel to the top of the heating chamber.

[0015] Furthermore, the furnace body also includes a heating element for providing heat to the heating chamber.

[0016] Furthermore, a thermal insulation layer is provided on the inner wall of the thermal insulation cover.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] By using the translation assembly and the lifting arm, when the insulation cover needs to be opened, the lifting arm can lift the insulation cover, and then the rotating roller rotates counterclockwise to drive the translation frame and the insulation cover to move, so that the insulation cover can be away from the heating chamber. When installing the insulation cover, the rotating roller rotates clockwise to make the translation frame drive the insulation cover to move above the heating chamber again, and then the lifting arm pushes the insulation cover down until it closes with the heating chamber. This method is more stable than the traditional rope crane movement, improves the connection rigidity, reduces the shaking during the movement, improves the disassembly and assembly stability of the insulation cover and the accuracy of the lower cover, thereby improving the sealing of the tempering furnace.

[0019] By setting the slide groove and the slide rail, the friction between the clamping block and the slide rail can be reduced, so that the translation frame can move more smoothly, reduce the vibration of the translation frame during movement, and improve the stability during the capping process.

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: In the prior art, in order to maintain a constant temperature inside the tempering furnace, the current practice is to use an insulation cover to seal the furnace body. In the existing technical solution, the insulation cover is usually moved with the help of a crane and a hanging rope. However, during the movement, due to the effect of inertia, the insulation cover suspended by the hanging rope will shake, which means that when installing the insulation cover, the operator must use tools or manually hold the insulation cover steady to ensure that it can cover the furnace body stably.

[0028] Therefore, in order to solve the problem that the existing insulation cover will be unstable and inconvenient to use during the sealing operation, and to improve the stability of the insulation cover during movement and the function of improving the sealing efficiency, the utility model discloses a furnace body mobile sealing mechanism, Figure 1-Figure 2 , including an insulation cover 2, a translation assembly for horizontally moving the insulation cover 2, including a translation frame 3 arranged parallel to the insulation cover 2 above the insulation cover 2, and a slide 4 opened on the ground, the translation frame 3 includes a frame foot perpendicular to the ground, a lifting arm 8, arranged between the insulation cover 2 and the translation frame 3, for lifting or lowering the insulation cover 2, a slide rail 5 is provided in the slide 4, and a clamping block 6 movably connected to the slide rail 5 is provided at the frame foot of the translation frame 3, and rotating rollers 7 that are in contact with the ground are further provided on both sides of the clamping block 6, and the rotating rollers 7 are perpendicular to the extension direction of the slide 4;

[0029] When the heat preservation cover 2 is to be installed, the rotating roller 7 can be rotated clockwise on the ground so that the translation frame 3 can move the heat preservation cover 2 to the top of the heating chamber 12 opening. Then, the lifting arm 8 can push the heat preservation cover 2 toward the heating chamber 12 until the heat preservation cover 2 and the heating chamber 12 are closed. In this way, compared with the prior art of moving the heat preservation cover 2 by using a lifting rope and a crane, the use of the lifting arm 8 and the translation frame 3 can improve the connection rigidity of the heat preservation cover 2 and the driving device, so that the heat preservation cover 2 will not shake due to inertia during the movement, thereby improving the stability and accuracy of the heat preservation cover 2 during disassembly and assembly.

[0030] Furthermore, the lifting arm 8 is controlled by a lifting device, wherein the lifting device is arranged on the translation frame 3, and the lifting device can be a motor or a hydraulic device.

[0031] In this embodiment, a driving member for rotating the rotating roller 7 is provided in the clamping block 6. The driving member can be a rotor motor or other driving device.

[0032] Optionally, in order to ensure accurate positioning of the translation frame 3 , the driving member of the rotating roller 7 may be connected to a host computer, so as to control the moving distance and speed of the translation frame 3 .

[0033] Furthermore, in order to reduce vibration of the translation frame 3 during movement, the setting of the slide rail 5 can reduce the friction between the clamping block 6 and the slide rail 5, so that the translation frame 3 can move more smoothly and improve the stability during the capping process.

[0034] In this embodiment, the translation frame 3 is made of a rigid material, such as stainless steel.

[0035] In this embodiment, the slide rail 5 is a strip-shaped stainless steel structure with a smooth surface.

[0036] Example 2: Based on Example 1, in order to reduce the deviation of the running track during the movement of the translation frame 3, refer to Figure 3 The present invention further includes a limiting groove 9 and a clamping block 10 for improving the tightness between the clamping block 6 and the slide rail 5. Specifically, the limiting grooves 9 are provided on both sides of the slide rail 5, and the clamping block 10 is provided on the inner wall of the clamping block 6, wherein the clamping block 10 is movably clamped in the limiting groove 9;

[0037] In this embodiment, the shape of the limit groove 9 matches the shape of the block 10 to ensure that the block 10 can be engaged in the limit groove 9. When the translation frame 3 moves on the slide rail 5, since the block 10 is engaged on both sides of the limit groove 9, the lateral movement of the clamping block 6 can be limited, thereby reducing the deviation of the running track caused by lateral force.

[0038] In one embodiment, to prevent jamming between the clamping block 10 and the limiting groove 9, a pulley 11 is provided on the side of the clamping block 10 facing the inner wall of the limiting groove 9. This allows the clamping block 10 to move smoothly within the limiting groove 9, further ensuring the stability of the translation frame 3 during movement. The pulley 11 can be made of a wear-resistant material, such as polytetrafluoroethylene or ceramic, to reduce wear and extend its service life.

[0039] Example 3: Based on Example 1, in order to improve the grip of the rotating roller 7 and prevent the rotating roller 7 from idling on the ground, refer to Figure 1 , the utility model also includes a protrusion for increasing friction. Specifically, the roller body of the rotating roller 7 is provided with a plurality of protrusions;

[0040] In this embodiment, the shape of the bumps can be cylindrical, conical, or other shapes that can increase friction, so as to ensure that the rotating roller 7 can better grip the ground during movement, thereby improving the stability of the translation frame 3. The material of the bumps can be rubber or metal, and the selection is based on the actual ground material and friction requirements.

[0041] In order to further improve the grip of the rotating roller 7, a layer of material with a high friction coefficient, such as rubber or Teflon coating, can be coated on the surface of the roller body of the rotating roller 7. This coating can not only increase the friction with the ground, but also absorb vibration to a certain extent, thereby reducing the vibration and noise of the translation frame 3 during movement.

[0042] Example 4, combined with Example 1 to Example 3, refer to Figures 1-4 The present invention also proposes a high-temperature tempering furnace, comprising a furnace body 1 embedded in the ground and a furnace body movable cover mechanism, wherein the furnace body 1 comprises a heating chamber 12 for heating workpieces, the chute 4 is arranged parallel to the ground on both sides of the opening of the heating chamber 12, and the heat preservation cover 2 is arranged parallel to the top of the heating chamber 12;

[0043] The operating principle of this high-temperature tempering furnace is as follows: when a workpiece needs to be heated, the insulation cover 2 is first raised to a certain height by the lifting arm 8. Then, the translation frame 3 is moved to move the insulation cover 2 away from the opening of the heating chamber 12. At this point, the workpiece can be placed in the heating chamber 12. The insulation cover 2 is then returned to its original position by the translation frame 3, and the lifting arm 8 slowly lowers the insulation cover 2 until it completely covers the heating chamber 12, ensuring the heat preservation effect during the heating process.

[0044] In this embodiment, the high-temperature tempering furnace further includes heating elements for controlling the temperature within the furnace. These heating elements may be resistance wires, heat pipes, or other heating methods suitable for high-temperature operations. The heating elements are evenly arranged on the bottom or side walls of the heating chamber 12 to ensure uniform heating of the workpiece throughout the heating process.

[0045] In order to further improve the heat preservation performance of the furnace body, a heat insulation layer is provided on the inner wall of the heat preservation cover (2), and the heat insulation layer is made of heat preservation materials, such as ceramic fiber, aluminum silicate fiber, etc. These materials have good heat insulation performance and can effectively reduce the heat loss of the furnace body, thereby improving energy utilization efficiency;

[0046] In addition, the clamping groove 10 can also play the role of clamping the two ends of the grading blade 2, thereby improving the overall stability of the grading blade 2.

[0047] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0048] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
