Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace technology, specifically a vacuum furnace that can quickly feed and discharge materials. Background Technology

[0002] A vacuum furnace is an industrial device that heats materials in a vacuum environment. It is commonly used for heat treatment, processing, and preparation of materials. Vacuum furnaces completely eliminate oxidation and decarburization on the surface of steel components during the heating process, resulting in a clean surface without any altered layer. Vacuum furnaces have a wide range of applications and are therefore increasingly used in the processing of materials.

[0003] Existing vacuum furnaces generally suffer from the following problems in material loading and unloading: First, traditional feeding methods mostly rely on manual or simple mechanical transmission, resulting in low material loading and unloading efficiency and difficulty in meeting the needs of large-scale continuous production; Second, the sealed furnace door and feeding mechanism are independent of each other, making the operation process cumbersome and prone to causing a decrease in the vacuum level inside the furnace due to poor sealing, affecting the stability of the processing technology; Third, the protective devices are usually fixed structures or require manual opening and closing, which cannot be automatically matched with the feeding process, posing a risk of material falling and safety hazards for operators coming into contact with high-temperature components. In view of this, we propose a vacuum furnace that can quickly load and unload materials to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum furnace that can quickly feed and discharge materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum furnace capable of rapidly loading and unloading materials, comprising a furnace body, a feeding mechanism, a control box, casters, a protective mechanism, guide rails, and tooling. Control boxes are located on both sides of the furnace body, and casters are located below each control box. A processing tank is opened within the furnace body, and guide rails are symmetrically arranged within the processing tank. Tooling is slidably connected to the guide rails, and a gear-driven feeding mechanism is provided between the furnace body and the tooling. A protective mechanism is located below the opening of the processing tank on the furnace body.

[0006] Preferably, the feeding mechanism includes a swing arm, a drive wheel, a sealed furnace door, a transmission rack, a connector, a first transmission rod, a second transmission rod, a transmission component, a first rotating shaft, a second rotating shaft, and a limiting groove. The swing arm is movably connected to one side of the furnace body, and a sealed furnace door is provided on one side of the swing arm, with the sealed furnace door cooperating with the opening of the processing tank. The swing arm is provided with a drive wheel inside the furnace body, and a transmission rack is provided on the side of the furnace body near the drive wheel. A connector is provided on the side of the transmission rack away from the drive wheel. The connector is movably connected to the first transmission rod, and the first transmission rod is movably connected to the second transmission rod on the side away from the connector. The middle portions of the first and second transmission rods are respectively provided with the second rotating shaft and the first rotating shaft inside the furnace body.

[0007] Preferably, a transmission component is fixedly connected to one side of the tooling, and a transmission component is movably connected to the side of the second transmission rod away from the first transmission rod. The transmission rack and the drive wheel mesh with each other, a limit groove is opened below the transmission rack, and a limit block is provided on the side of the furnace body near the limit groove. The limit block and the limit groove cooperate with each other.

[0008] Preferably, the protective mechanism includes a receiving groove, a pressing block, a guide rod, a return spring, a protective plate, a fixing rod, and a guide groove. The furnace body has a receiving groove below the opening of the processing groove. A protective plate is slidably connected in the receiving groove. A fixing rod is provided on one side of the protective plate. A guide rod is provided on the side of the receiving groove away from the fixing rod. A guide groove is provided on the side of the protective plate near the guide rod. A return spring is sleeved on the guide rod between the receiving groove and the protective plate.

[0009] Preferably, a pressing block is fixedly connected to one side of the transmission rack in the receiving groove, the pressing block and the fixing rod cooperate with each other, and the protective plate has a U-shaped structure.

[0010] Preferably, the sealed furnace door is provided with multiple layers of sealing strips, which are arranged around the edge of the sealed furnace door that contacts the opening of the processing tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the sealed furnace door is closed, the swing arm drives the drive wheel to rotate. Since the drive wheel meshes with the transmission rack, it is converted into linear motion of the transmission rack. During this process, the limit block and the limit groove cooperate to limit the movement range of the transmission rack. When the transmission rack moves, it drives the first transmission rod to move through the connecting piece. The middle part of the first transmission rod is rotatably connected to the furnace body through the second rotating shaft. Therefore, under the drive of the connecting piece, the first transmission rod swings around the second rotating shaft. At the same time, the first transmission rod drives the second transmission rod to move through the movable connection. The second transmission rod swings around the first rotating shaft. The side of the second transmission rod away from the first transmission rod is movably connected to the transmission component fixedly connected to the tooling. When the second transmission rod swings, it will push the tooling to slide along the guide rail through the transmission component, quickly entering or leaving the processing tank inside the furnace body.

[0013] 2. When the tooling is removed, the swing arm rotates the drive wheel, which drives the transmission rack to move horizontally. Since the extrusion block is fixedly connected to one side of the transmission rack and located in the receiving groove, the movement of the transmission rack will synchronously drive the extrusion block to move. As the extrusion block moves towards the protective plate, it gradually contacts and pushes the fixed rod. The fixed rod is fixed to one side of the protective plate. The protective plate slides with the guide rod through the guide groove, so that the protective plate can only move in a straight line along the direction of the guide rod. When the extrusion block pushes the fixed rod, the protective plate overcomes the elastic force of the return spring under the thrust and extends out of the receiving groove along the guide rod. At this time, the U-shaped protective plate will unfold below the opening of the processing tank, with its U-shaped opening facing upwards. This can effectively prevent materials from falling accidentally and prevent operators from accidentally touching high-temperature areas or moving parts, thus playing a safety protection role.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figure 1-4As shown, the present invention proposes a vacuum furnace for rapid material loading and unloading, comprising a furnace body 1, a feeding mechanism 2, a control box 3, casters 4, a protective mechanism 5, guide rails 6, and tooling 7. Control boxes 3 are provided on both sides of the furnace body 1, and casters 4 are provided below each control box 3. A processing groove 8 is provided inside the furnace body 1, and guide rails 6 are symmetrically arranged inside the processing groove 8. Tooling 7 is slidably connected to the guide rails 6, and a gear-driven feeding mechanism 2 is provided between the furnace body 1 and the tooling 7. A protective mechanism 5 is provided below the opening of the processing groove 8 on the furnace body 1.

[0021] In an optional embodiment, the feeding mechanism 2 includes a swing arm 201, a drive wheel 202, a sealed furnace door 203, a transmission rack 204, a connecting piece 205, a first transmission rod 206, a second transmission rod 207, a transmission piece 208, a first rotating shaft 209, a second rotating shaft 210, and a limiting groove 211. The swing arm 201 is movably connected to one side of the furnace body 1, and a sealed furnace door 203 is provided on one side of the swing arm 201. The sealed furnace door 203 cooperates with the opening of the processing tank 8. A drive wheel 202 is provided inside the furnace body 1, and a transmission rack 204 is provided on the side of the furnace body 1 near the drive wheel 202. A connecting member 205 is provided on the side of the transmission rack 204 away from the drive wheel 202. A first transmission rod 206 is movably connected to the connecting member 205, and a second transmission rod 207 is movably connected on the side of the first transmission rod 206 away from the connecting member 205. A second rotating shaft 210 and a first rotating shaft 209 are respectively provided in the middle parts of the first transmission rod 206 and the second transmission rod 207 inside the furnace body 1.

[0022] In an optional embodiment, a transmission component 208 is fixedly connected to one side of the tooling 7, and the transmission component 208 is movably connected to the side of the second transmission rod 207 away from the first transmission rod 206. The transmission rack 204 meshes with the drive wheel 202. A limiting groove 211 is provided below the transmission rack 204. A limiting block 212 is provided on the side of the furnace body 1 near the limiting groove 211. The limiting block 212 and the limiting groove 211 cooperate with each other.

[0023] When the sealed furnace door 203 is closed, the swing arm 201 drives the drive wheel 202 to rotate. Since the drive wheel 202 meshes with the transmission rack 204, this is converted into linear motion of the transmission rack 204. During this process, the limiting block 212 engages with the limiting groove 211 to limit the movement range of the transmission rack 204. When the transmission rack 204 moves, it drives the first transmission rod 206 to move via the connecting piece 205. The middle part of the first transmission rod 206 is rotatably connected to the furnace body 1 via the second rotating shaft 210. Therefore, at the connecting piece 205... Driven by 5, the first transmission rod 206 swings around the second rotating shaft 210. At the same time, the first transmission rod 206 drives the second transmission rod 207 to move through a movable connection. The second transmission rod 207 swings around the first rotating shaft 209. The side of the second transmission rod 207 away from the first transmission rod 206 is movably connected to the transmission component 208 fixedly connected to the tooling 7. When the second transmission rod 207 swings, it will push the tooling 7 to slide along the guide rail 6 through the transmission component 208, quickly entering or leaving the processing tank 8 in the furnace body 1.

[0024] In an optional embodiment, the protective mechanism 5 includes a receiving groove 501, a pressing block 502, a guide rod 503, a return spring 504, a protective plate 505, a fixing rod 506, and a guide groove 507. The furnace body 1 has a receiving groove 501 below the opening of the processing groove 8. A protective plate 505 is slidably connected in the receiving groove 501. A fixing rod 506 is provided on one side of the protective plate 505. A guide rod 503 is provided on the side of the receiving groove 501 away from the fixing rod 506. A guide groove 507 is provided on the side of the protective plate 505 near the guide rod 503. A return spring 504 is sleeved on the guide rod 503 between the receiving groove 501 and the protective plate 505.

[0025] In an optional embodiment, a pressing block 502 is fixedly connected to one side of the transmission rack 204 in the receiving groove 501. The pressing block 502 and the fixing rod 506 cooperate with each other, and the protective plate 505 has a U-shaped structure.

[0026] When tooling 7 is removed, swing arm 201 causes drive wheel 202 to rotate, driving transmission rack 204 to move horizontally. Since extrusion block 502 is fixedly connected to one side of transmission rack 204 and located in storage groove 501, the movement of transmission rack 204 will synchronously drive extrusion block 502 to move. As extrusion block 502 moves towards protective plate 505, it gradually contacts and pushes fixed rod 506. Fixed rod 506 is fixed to one side of protective plate 505. Protective plate 505 is connected to guide rod 506 through guide groove 507. The sliding fit of 03 allows the protective plate 505 to move only in a straight line along the direction of the guide rod 503. When the extrusion block 502 pushes the fixing rod 506, the protective plate 505, under the action of the thrust, overcomes the elastic force of the return spring 504 and extends out of the storage groove 501 along the guide rod 503. At this time, the U-shaped protective plate 505 will unfold below the opening of the processing groove 8, with its U-shaped opening facing upwards. This can effectively prevent materials from falling accidentally and prevent operators from accidentally touching high-temperature areas or moving parts, thus playing a safety protection role.

[0027] In an optional embodiment, the sealed furnace door 203 is provided with multiple layers of sealing strips, which are arranged around the edge of the sealed furnace door 203 that contacts the groove of the processing tank 8.

[0028] The working principle of this utility model is as follows: When using this device, when the sealed furnace door 203 is closed, the swing arm 201 drives the drive wheel 202 to rotate. Since the drive wheel 202 meshes with the transmission rack 204, it is converted into linear motion of the transmission rack 204. During this process, the limiting block 211 cooperates with the limiting groove 211 to limit the movement range of the transmission rack 204. When the transmission rack 204 moves, it drives the first transmission rod 206 to move through the connecting piece 205. The middle part of the first transmission rod 206 is rotatably connected to the furnace body 1 through the second rotating shaft 210. Therefore, driven by the connecting piece 205, the first transmission rod 206 swings around the second rotating shaft 210. At the same time, the first transmission rod 206 drives the second transmission rod 207 to move through a movable connection. The second transmission rod 207 swings around the first rotating shaft 209. The side of the second transmission rod 207 away from the first transmission rod 206 is movably connected to the transmission piece 208 fixedly connected to the tooling 7. When the second transmission rod 207 swings, it will push the tooling 7 to slide along the guide rail 6 through the transmission piece 208, quickly entering or leaving the processing tank 8 inside the furnace body 1.

[0029] When tooling 7 is removed, swing arm 201 causes drive wheel 202 to rotate, driving transmission rack 204 to move horizontally. Since extrusion block 502 is fixedly connected to one side of transmission rack 204 and located in storage groove 501, the movement of transmission rack 204 will synchronously drive extrusion block 502 to move. As extrusion block 502 moves towards protective plate 505, it gradually contacts and pushes fixed rod 506. Fixed rod 506 is fixed to one side of protective plate 505. Protective plate 505 is connected to guide rod 506 through guide groove 507. The sliding fit of 03 allows the protective plate 505 to move only in a straight line along the direction of the guide rod 503. When the extrusion block 502 pushes the fixing rod 506, the protective plate 505, under the action of the thrust, overcomes the elastic force of the return spring 504 and extends out of the storage groove 501 along the guide rod 503. At this time, the U-shaped protective plate 505 will unfold below the opening of the processing groove 8, with its U-shaped opening facing upwards. This can effectively prevent materials from falling accidentally and prevent operators from accidentally touching high-temperature areas or moving parts, thus playing a safety protection role.
