Description

Technical Field

[0001] This utility model relates to the field of box-type resistance furnace technology, specifically to an assembly shell structure for a box-type resistance furnace. Background Technology

[0002] Box-type resistance furnaces are widely used heat treatment equipment in metallurgy, machinery manufacturing and materials research. They are mainly used for annealing, quenching and tempering of metal parts. Traditional box-type resistance furnaces usually consist of a furnace body, heating elements, insulation layer and a front-opening sealed door.

[0003] Referring to the patent document: Patent Publication No. CN216432528U, Patent Publication Date 2022-05-03, this invention relates to a heat dissipation structure for a box-type resistance furnace, including a furnace shell, a water-cooling mechanism and a circulation mechanism on the right side of the furnace shell, an air-cooling mechanism on the top of the furnace shell, and a cleaning mechanism on the top of the air-cooling mechanism. A temperature sensor is embedded inside the furnace shell. The water-cooling mechanism includes a chamber, heat dissipation pipes, an internal cooling unit, and an external heat dissipation unit. The chamber is fixedly installed on the right side of the furnace shell, and the heat dissipation pipes are fixedly installed inside the chamber. This heat dissipation structure for the box-type resistance furnace, through the water-cooling mechanism and the circulation mechanism, can circulate and reduce the temperature of the cooling water inside the water-cooling layer. Furthermore, the air-cooling mechanism can further accelerate the cooling rate of the cooling water inside the water-cooling layer, enabling rapid cooling of the interior of the furnace shell and achieving efficient heat dissipation.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Traditional box-type resistance furnaces rely mainly on manual labor for loading and unloading. Operators place or remove heat-treated workpieces by inserting their hands or tools into the high-temperature furnace cavity. Since the furnace cavity still retains a large amount of heat after heat treatment, with temperatures reaching hundreds to thousands of degrees Celsius, manual operation can easily lead to burns and other safety accidents. In addition, after completing one heat treatment cycle, the large amount of heat accumulated in the furnace cavity is difficult to dissipate quickly. Usually, the only way to proceed is to open the sealed door and wait for the furnace temperature to slowly drop to a safe range before loading the next batch. This process is often time-consuming, resulting in low production efficiency and low work turnover rate of the equipment.

[0006] Therefore, this utility model provides an assembly shell structure for a box-type resistance furnace. Utility Model Content

[0007] To address the safety hazards of manual loading and unloading operations in traditional box-type resistance furnaces, which can easily lead to burns, and the problems of long cooling times that result in low production efficiency, the purpose of this utility model is to provide an assembly shell structure for box-type resistance furnaces.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an assembly shell structure for a box-type resistance furnace, comprising a box-type resistance furnace body, a sealed door hinged to one side of the box-type resistance furnace body, and an auxiliary mechanism in the middle of the box-type resistance furnace body for assisting operators in loading and unloading metal parts requiring heat treatment. The auxiliary mechanism includes:

[0009] The telescopic assembly includes a swing frame rotatably mounted on one side of the lower part of the box-type resistance furnace body. A drive assembly is provided on one side of the lower part of the swing frame. A movable frame is slidably mounted on the upper part of the box-type resistance furnace body. Two symmetrically distributed sliding grooves are opened on the lower part of the movable frame. One end of the upper part of the swing frame is slidably mounted in the middle of the sliding groove. A placement frame is fixedly mounted on one side of the movable frame. One side of the placement frame slides through one side of the middle part of the box-type resistance furnace body.

[0010] The heat dissipation component is located on the upper side of the main body of the box-type resistance furnace and is used to quickly dissipate heat from inside the main body of the box-type resistance furnace.

[0011] Preferably, the heat dissipation component includes a movable cylinder fixedly installed on one side of the upper part of the box-type resistance furnace body, a sealing block fixedly installed on the drive end of the movable cylinder, a slot is opened on the upper part of the box-type resistance furnace body, and two symmetrically distributed exhaust slots are opened on one side of the upper part of the box-type resistance furnace body, and both exhaust slots are connected to the slot.

[0012] Preferably, the drive assembly includes a drive cylinder disposed at the lower part of the box-type resistance furnace body, and the lower part of the swing frame is movably mounted on the drive end of the drive cylinder.

[0013] Preferably, the lower part of the box-type resistance furnace body has a cavity, and the lower part of the drive cylinder is movably installed inside the cavity.

[0014] Preferably, the slot has a T-shaped structure, and the slot is connected to the heating chamber of the box-type resistance furnace body, with the sealing block slidably locked inside the slot.

[0015] Preferably, a dustproof plate is attached to one end of each of the two exhaust channels, and the two dustproof plates are fixed to one end of the exhaust channel by bolts.

[0016] Beneficial effects

[0017] This utility model provides an assembly shell structure for a box-type resistance furnace. Compared with the prior art, it has the following advantages:

[0018] 1. This application uses a drive cylinder to drive the swing frame to deflect around the hinge point, and its upper part slides in the sliding groove of the moving frame, which drives the placement frame to move horizontally. When loading, the placement frame extends out of the furnace to avoid personnel contact with the high-temperature furnace cavity; when unloading, it also moves outward to facilitate the removal of parts, avoiding direct contact with the high-temperature furnace cavity and greatly reducing the risk of burns.

[0019] 2. When heat dissipation is required, the moving cylinder will drive the T-shaped sealing block to move backward, so that its front end is freed from the constraint of the slot, making the furnace cavity and the exhaust channel connected. With the opening of the sealing door, convection is formed, and the high-temperature air is quickly discharged through the exhaust channel. Heat dissipation is accelerated by air convection, which greatly shortens the cooling waiting time, improves the heat dissipation efficiency of the equipment, and greatly shortens the waiting time for cooling between batch operations.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a technical solution: an assembly shell structure for a box-type resistance furnace, including a box-type resistance furnace body 1, a sealing door 11 hinged to one side of the box-type resistance furnace body 1, and a high-temperature resistant sealing strip embedded in the inner edge of the sealing door 11; an auxiliary mechanism 2 is provided in the middle of the box-type resistance furnace body 1 to assist operators in loading and unloading metal parts that require heat treatment; the auxiliary mechanism 2 includes:

[0027] The telescopic assembly 21 includes a swing frame 212 rotatably mounted on one side of the lower part of the box-type resistance furnace body 1. A drive assembly is provided on one side of the lower part of the swing frame 212. A movable frame 213 is slidably mounted on the upper part of the box-type resistance furnace body 1. Two symmetrically distributed sliding grooves 214 are provided on the lower part of the movable frame 213. One end of the upper part of the swing frame 212 is slidably mounted in the middle of the sliding groove 214. The upper part of the swing frame 212 is slidably mounted in the sliding groove 214, which allows the swing frame 212 to slide within the sliding groove 214, thereby ensuring that it can smoothly complete the deflection operation. Thus, during the deflection process, the swing frame 212 will drive the movable frame 213 to move horizontally. One side of the movable frame 213 is fixed. A placement rack 215 is installed, with one side of the placement rack 215 sliding through the middle side of the box-type resistance furnace body 1. During operation, one end of the swing frame 212 can be driven to move diagonally downward, causing the swing frame 212 to deflect around the hinge point at the lower part of the box-type resistance furnace body 1. This causes the swing frame 212 to drive the upper moving frame 213 to move horizontally, thereby controlling the position of the placement rack 215. When the placement rack 215 is located at the center of the box-type resistance furnace body 1, the metal parts placed on it are heat-treated. After the treatment is completed, the placement rack 215 extends outward through horizontal movement, making it easier and safer for workers to remove the heat-treated metal parts.

[0028] The heat dissipation component 22 is located on the upper side of the box-type resistance furnace body 1 and is used to quickly dissipate the heat inside the box-type resistance furnace body 1.

[0029] The heat dissipation assembly 22 includes a movable cylinder 221 fixedly installed on one side of the upper part of the box-type resistance furnace body 1. A sealing block 222 is fixedly installed on the drive end of the movable cylinder 221. A slot 223 is opened on the upper part of the box-type resistance furnace body 1. Two symmetrically distributed exhaust slots 224 are opened on one side of the upper part of the box-type resistance furnace body 1. Both exhaust slots 224 are connected to the slot 223. The movable cylinder 221 adopts the SC series standard cylinder ISO-VDMA. When it is necessary to dissipate heat from the heating chamber in the box-type resistance furnace body 1, the movable cylinder 221 is started at the same time as the sealing door 11 is opened, so that it drives the sealing block 222 to move backward along the slot 223, so that the sealing block 222 is disengaged from the front end of the T-shaped structure of the slot 223. At this time, the heating chamber of the box-type resistance furnace body 1 is connected to the slot 223 and the exhaust slots 224. Air convection is formed through the front sealing door 11, so that the internal temperature can be quickly dissipated.

[0030] The drive assembly includes a drive cylinder 211 located at the lower part of the box-type resistance furnace body 1. The lower part of the swing frame 212 is movably mounted on the drive end of the drive cylinder 211. The drive cylinder 211 is an SMC standard cylinder model JMDBB32-50-M9BW, which can drive the swing frame 212 to deflect around the hinge point. When the drive end of the drive cylinder 211 extends outward, the placement frame 215 can move into the heating chamber of the box-type resistance furnace body 1 under the transmission of the swing frame 212. When it retracts downward (inward), the placement frame 215 can move out of the heating chamber of the box-type resistance furnace body 1 under the transmission of the swing frame 212.

[0031] The lower part of the box-type resistance furnace body 1 is provided with a cavity 216, and the lower part of the drive cylinder 211 is movably installed inside the cavity 216. By providing the cavity 216, a working space can be provided for the movement of the drive cylinder 211 and the swing frame 212.

[0032] The slot 223 has a T-shaped structure and is connected to the heating chamber of the box-type resistance furnace body 1. The sealing block 222 is slidably locked inside the slot 223. The cross-section of the sealing block 222 is also T-shaped, but the rear end of the T-shaped structure is smaller than the rear end of the T-shaped structure of the slot 223. This ensures that when the front end of the sealing block 222 falls off the front end of the slot 223, the heating chamber of the box-type resistance furnace body 1 can be connected to the slot 223 and the exhaust groove 224.

[0033] Dustproof plates 225 are installed at one end of each of the two exhaust slots 224. Both dustproof plates 225 are fixed to one end of the exhaust slots 224 by bolts. By setting dustproof plates 225, impurities can be prevented from entering the exhaust slots 224 and affecting the normal heat dissipation.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when the drive end of the drive cylinder 211 is in a retracted state, the swing frame 212 deflects around the hinge point between itself and the lower part of the box-type resistance furnace body 1 under the traction of the drive cylinder 211. Through its upper end sliding in the sliding groove 214 of the moving frame 213, it drives the entire moving frame 213 and the placement frame 215 fixed on one side to move horizontally out of the furnace, so that most of the placement frame 215 extends out of the heating chamber of the box-type resistance furnace body 1. The operator can conveniently and safely place the metal parts to be heat-treated on the exposed placement frame 215, avoiding the risk of putting hands or tools into the high-temperature furnace chamber. The same method is also used for unloading and taking out the materials.

[0036] After the material is loaded, start the drive cylinder 211, and extend its drive end outward to push the lower part of the swing frame 212, causing the swing frame 212 to deflect in the opposite direction around the hinge point. This movement, through the cooperation of the sliding groove 214 and the upper end of the swing frame 212, causes the moving frame 213 to move horizontally inward, thereby smoothly sending the placement frame 215 carrying the workpiece into the center of the heating chamber of the box-type resistance furnace body 1. Close the sealing door 11, and the heat treatment of the metal parts can begin.

[0037] When rapid cooling of the furnace cavity is required, the moving cylinder 221 is activated to drive the sealing block 222 to move backward along the T-shaped slot 223 while the sealing door 11 is opened. Since the rear end of the sealing block 222 is smaller than the rear end of the slot 223, when its T-shaped front end is freed from the T-shaped front constraint of the slot 223, a through airflow channel is formed between the top of the furnace cavity and the slot 223 and the two exhaust slots 224 connected to it. At this time, the opened sealing door 11 serves as the air inlet, and the through exhaust slot 224 on the other side serves as the air outlet, causing air convection. The high-temperature air inside is quickly discharged through the exhaust slot 224, thereby achieving rapid heat dissipation inside the box-type resistance furnace body 1 and significantly improving cooling efficiency.
