Description
Technical Field
[0001] This utility model generally relates to the field of forging technology, and specifically to a closed heating furnace and an automatic heating device. Background Technology
[0002] In the copper forging process, in order to improve the metal plasticity of copper and reduce its deformation resistance, the copper needs to be heated before forging. Current technology usually uses a heating furnace to heat the copper. Traditional heating furnaces are heated manually. After the workers transport the material to the heating furnace via a transfer cart, they need to manually fill the furnace chamber with the material, then start the nozzles to heat the material in the furnace chamber. After the material is heated to a suitable temperature, it is manually shoveled out and transported to the next process.
[0003] However, traditional manual heating furnaces have the following problems: 1. Workers need to manually fill and remove materials from the furnace chamber, making the feeding and unloading operations of the heating furnace cumbersome and labor-intensive; 2. Heating time cannot be precisely controlled, requiring workers to judge based on experience, which may result in heating time being too long or too short, affecting product quality; 3. The furnace chamber of traditional heating furnaces has an open structure, and the heat from the furnace chamber is easily dissipated into the workshop, which not only increases energy consumption but also leads to a higher working environment temperature in the workshop. Summary of the Invention
[0004] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a closed heating furnace and an automatic heating device. Under the continuous pushing of the top-push cylinder, a number of materials can automatically slide from the input end to the output end and then be output to the next process, thereby making the material loading and unloading operations simpler and reducing the labor intensity of the workers. Moreover, the constant pushing speed of the top-push cylinder makes the time for the material to slide from the input end to the output end also fixed, that is, the heating time of the materials is consistent, ensuring product quality. In addition, since the materials are connected end to end in the furnace cavity, the front and rear ports of the furnace cavity are blocked by the materials, which makes it difficult for the heat in the furnace cavity to dissipate, resulting in good heat preservation, reducing unnecessary fuel consumption, and improving the temperature of the working environment.
[0005] The effect of this utility model is achieved as follows:
[0006] In a first aspect, this application provides a closed heating furnace, including a furnace body, a furnace cavity extending through the furnace body in a front-to-back direction, a heating mechanism disposed within the furnace cavity, the heating mechanism being configured to heat materials; a plurality of slide rails extending in a front-to-back direction are laid at the bottom of the furnace cavity, the front end of the slide rails passing through the front port of the furnace cavity to form an input end, the rear end of the slide rails being close to the rear port of the furnace cavity to form an output end, and a push cylinder is also disposed at the front end of the slide rails; whenever materials are filled into the input end, the push cylinder pushes the materials backward, and as the push cylinder continues to operate, the subsequently input materials continuously push the previously input materials backward, thereby causing a plurality of materials to gradually slide along the slide rails, and after being heated by the heating mechanism, to be output from the output end.
[0007] Furthermore, a temperature measuring mechanism is installed inside the furnace cavity, including a thermocouple and an infrared thermometer. The thermocouple is located in the middle of the furnace cavity and is configured to detect the furnace cavity temperature, while the infrared thermometer is located inside the furnace cavity near the output end and is configured to detect the product temperature. This allows staff to intuitively understand the current product temperature and furnace cavity temperature values, facilitating temperature control and preventing excessively high or low temperatures, thus ensuring product quality.
[0008] Furthermore, the enclosed heating furnace also includes a CNC mechanism, which includes a control panel located on one side of the furnace body. The CNC mechanism connects to the temperature measuring mechanism and the heating mechanism. The control panel is configured to compare the data detected by the temperature measuring mechanism with the heating temperature range preset by the operator, and automatically adjust the heating temperature of the heating mechanism. This provides more precise control over the heating temperature, eliminating the need for operators to rely on experience to judge the heating temperature and time, simplifying operation while further ensuring product quality.
[0009] Furthermore, the bottom of the furnace chamber is equipped with two symmetrical sliding rails. This allows the furnace to heat and process two sets of materials simultaneously, improving work efficiency.
[0010] Furthermore, the jacking cylinders of the two slide rails alternately perform jacking operations from left to right. This ensures that only one piece of material is output from the output end at a time, and the material output rate is relatively uniform, thus matching the production cycle and facilitating subsequent forging processing.
[0011] Furthermore, the heating mechanism includes several burners, which are positioned at the upper end of the furnace cavity and directly opposite the slide rail. This ensures that when the enclosed heating furnace is in operation, the burners are aligned with the upper end of the material, and the material is evenly heated by the burners during its sliding motion, guaranteeing the heating effect.
[0012] Secondly, this application also provides an automatic heating device, including a feeding mechanism and a closed heating furnace. The feeding mechanism includes a receiving trough, a lifting conveyor belt, and a feeding pipe. The receiving trough is located on one of the left and right sides of the furnace body and is configured to hold materials. The feeding pipe is vertically positioned above the input end. The lifting conveyor belt is inclined, with one end extending into the receiving trough and the other end connected to the upper opening of the feeding pipe. By setting up the feeding mechanism, the lifting conveyor belt automatically lifts the material in the receiving trough to the top of the feeding pipe, and the material slides down from the feeding pipe to the input end by gravity. The feeding operation is automated, eliminating the need for manual feeding by personnel, further simplifying the feeding operation and reducing the labor intensity of workers.
[0013] Furthermore, the automatic heating device also includes a material lifting mechanism, which comprises a frame and a trolley for carrying materials. A guide rail is installed along the frame's height, and pulleys are slidably mounted on the guide rail, connected to the trolley. A lifting component is installed at the upper end of the frame, connected to the trolley via a connecting rod. The lifting component is configured to drive the trolley to move up and down along the guide rail. The guide rail is divided into a vertical section and a curved section from bottom to top. After the trolley enters the curved section, it flips along the curved section and pours material into the receiving trough. The material lifting mechanism automatically pours the material from the trolley into the receiving trough, further improving the ease of the loading operation. Furthermore, by controlling the lifting component, the lifting height of the trolley is controlled, thereby controlling the tilt angle of the trolley, ultimately controlling the quantity and speed of material output.
[0014] This application provides a closed heating furnace and automatic heating device. After the material is put into the input end, under the continuous pushing of the top-push cylinder, the next material pushes the previous material backward. Several materials are connected end to end and continuously slide along the slide rail, so that the material can automatically slide from the input end to the output end and then be output to the next process. This makes the material feeding and discharging operation more convenient and reduces the labor intensity of the workers. Moreover, the pushing speed of the top-push cylinder is constant, so the time for the material to slide from the input end to the output end is also fixed, that is, the heating time of several materials is consistent, ensuring product quality. In addition, since several materials are connected end to end in the furnace cavity, the front and rear ports of the furnace cavity are blocked by the material, thus forming a closed structure. This makes it difficult for the heat in the furnace cavity to dissipate, resulting in good heat preservation, reducing unnecessary fuel consumption, and improving the temperature of the working environment.
[0015] Furthermore, the temperature measuring mechanism and the heating mechanism are connected through a CNC mechanism. The control panel is configured to compare the data detected by the temperature measuring mechanism with the heating temperature range preset by the operator, and automatically adjust the heating temperature of the heating mechanism. This provides more precise control over the heating temperature, eliminating the need for operators to judge the heating temperature and time based on experience. The operation is simple and further ensures the quality of the product. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0026] Please refer to the attached document. Figure 1-7This application provides a closed heating furnace, including a furnace body 1. The furnace body 1 has a furnace cavity 110 extending through it in a front-to-back direction. A heating mechanism is installed inside the furnace cavity 110, which is configured to heat material 6. Several slide rails 120 extending in a front-to-back direction are laid at the bottom of the furnace cavity 110. The front end of the slide rail 120 extends out of the front port of the furnace cavity 110 and forms an input end 121. The rear end of the slide rail 120 is close to the rear port of the furnace cavity 110 and forms an output end 122. A push cylinder 130 is also provided at the front end of the slide rail 120. Whenever material is filled into the input end 121, the push cylinder 130 pushes the material 6 backward. As the push cylinder 130 continues to operate, the material 6 that is input later continuously pushes the material 6 that was input earlier backward, so that several materials 6 gradually slide along the slide rails 120. After being heated by the heating mechanism, they are output from the output end 122.
[0027] In this embodiment, after material 6 is placed into input end 122, under the continuous pushing of top-push cylinder 130, the next material 6 pushes the previous material 6 backward. Several materials 6 are connected end to end and continuously slide along slide rail 120, so that material 6 can automatically slide from input end 121 to output end 122 and then be output to the next process. This makes the feeding and discharging operation of material 6 more convenient and reduces the labor intensity of workers. In addition, the pushing speed of top-push cylinder 130 is constant, so the time for material 6 to slide from input end 121 to output end 122 is also fixed, that is, the heating time of several materials 6 is consistent, ensuring product quality. Moreover, since several materials 6 are connected end to end in furnace cavity 110, the front and rear ports of furnace cavity 110 are blocked by materials 6, thus forming a closed structure. This makes it difficult for heat in furnace cavity 110 to dissipate, resulting in good heat preservation, reducing unnecessary fuel consumption, and improving the temperature of the working environment.
[0028] Please refer to the attached document. Figure 3 and attached Figure 5 In some embodiments of this application, a temperature measuring mechanism is also provided in the furnace cavity 110. The temperature measuring mechanism includes a thermocouple 140 and an infrared thermometer 150. The thermocouple 140 is located in the middle of the furnace cavity 110 and is configured to detect the furnace cavity temperature. The infrared thermometer 150 is located in the furnace cavity 110 near the output end 122 and is configured to detect the product temperature.
[0029] In this embodiment, to ensure product quality, both the furnace cavity temperature and the product temperature need to be maintained within a certain range, thereby adjusting the heating temperature. Therefore, the furnace cavity temperature is measured by thermocouple 140, and the product temperature is measured by infrared thermometer 150. This allows staff to intuitively understand the current product and furnace cavity temperatures, facilitating temperature control and preventing excessively high or low temperatures, thus ensuring product quality.
[0030] Please refer to the attached document. Figure 2 In some embodiments of this application, the enclosed heating furnace also includes a numerical control mechanism, which includes a control panel 160 disposed on one side of the furnace body 1. The numerical control mechanism is connected to a temperature measuring mechanism and a heating mechanism. The control panel 160 is configured to compare the data detected by the temperature measuring mechanism with the heating temperature range preset by the operator and automatically adjust the heating temperature of the heating mechanism.
[0031] In this implementation, by setting up a CNC mechanism to automatically adjust the heating mechanism according to the data from the testing mechanism, the control of the heating temperature is more precise. There is no need for staff to judge the heating temperature and time based on experience. The operation is simple and the product quality is further guaranteed.
[0032] Please refer to the attached document. Figure 3-4 In some embodiments of this application, the bottom of the furnace cavity 110 is provided with two symmetrical slide rails 120. That is, the furnace body 1 can heat and process two sets of materials 6 simultaneously, improving work efficiency.
[0033] Of course, in other embodiments of this application, the number of slide rails 120 inside the furnace cavity 110 can also be three, four, five, etc.
[0034] Please refer to the attached document. Figure 3-5 In some embodiments of this application, the push cylinders 130 of the two slide rails 120 alternately perform push operations.
[0035] In this embodiment, during the forging of material 6, only one material 6 can be processed sequentially. This means that when the output times of material 6 on the left and right slide rails 120 are close, only one of them can be forged first, resulting in a mismatch in production rhythm. The other material 6 also experiences a temperature drop while waiting for processing, affecting the forging effect. Therefore, the two jacking cylinders 130 alternately jack, ensuring that only one material 6 is output from the output end 122 at a time, and that the output rate of material 6 is more uniform, thus matching the production rhythm and facilitating subsequent forging processing.
[0036] Please refer to the attached document. Figure 3-5 In some embodiments of this application, the heating mechanism includes a plurality of burners 170, which are disposed at the upper end of the furnace cavity 110 and directly opposite the slide rail 120. This ensures that when the enclosed heating furnace is in operation, the plurality of burners 170 are aligned with the upper end of the material 6, and the material 6 is evenly heated by the plurality of burners 170 during the sliding process, thus guaranteeing the heating effect.
[0037] The furnace body 1 has an air inlet 171 that is hollowed out on the side wall. The air inlet 171 is connected to several burners 170 and is configured to transport natural gas and provide fuel.
[0038] Please refer to the attached document. Figure 1-2This application also provides an automatic heating device, including a feeding mechanism and a closed heating furnace. The feeding mechanism includes a receiving trough 101, a lifting conveyor belt 2 and a feeding pipe 3. The receiving trough 101 is located on one side of the left and right sides of the furnace body 1 and is configured to receive material 6. The feeding pipe 3 is vertically located above the input end 121. The lifting conveyor belt 2 is inclined and one end of the lifting conveyor belt 2 extends into the receiving trough 101, and the other end is connected to the upper pipe opening of the feeding pipe 3.
[0039] In this embodiment, by setting up a feeding mechanism, the lifting conveyor belt 2 automatically lifts the material 6 in the receiving tank 101 to above the feeding pipe 3, and the material 6 slides down from the feeding pipe 3 to the input end 121 by gravity. Thus, the feeding operation is automated, eliminating the need for manual feeding by personnel, further simplifying the feeding operation and reducing the labor intensity of the workers.
[0040] Please refer to the attached document. Figure 6-7 In some embodiments of this application, the automatic heating device further includes a material lifting mechanism, which includes a frame 4 and a turnover cart 5 for carrying materials 6. A guide rail 410 is provided on the frame 4 along its own height direction, and a pulley is slidably provided on the guide rail 410. The pulley is connected to the turnover cart 5. A lifting member 420 is provided at the upper end of the frame 4. The lifting member 420 is connected to the turnover cart 5 through a connecting rod 421. The lifting member 420 is configured to drive the turnover cart 5 to perform lifting and lowering actions along the guide rail 410. The guide rail 410 is divided into a vertical part 411 and a curved part 412 from bottom to top. After the turnover cart 5 enters the curved part 412, the turnover cart 5 flips along the curved part 412 and pours the material into the receiving tank 101.
[0041] In this embodiment, the material 6 in the turnover cart 5 is automatically poured into the receiving tank 101 by the lifting mechanism, further improving the simplicity of the loading operation. Furthermore, the turnover cart 5 is lifted by the lifting member 420. Depending on the lifting height of the turnover cart 5, its position within the curved guide rail 412 varies. This different position within the curved section 412 results in different tilt angles for the turnover cart 5. A larger tilt angle results in more material 6 being discharged. By controlling the lifting member 420, the lifting height of the turnover cart 5 is controlled, thereby controlling the tilt angle and ultimately controlling the quantity and speed of material 6 discharged.
[0042] Preferably, the lifting component 420 is an electric hoist, which is simple to operate, provides stable lifting, has a strong load-bearing capacity, and can lift a large number of materials 6.
[0043] The receiving tank 101 is provided with an inclined connecting groove 102. The higher side of the connecting groove 102 is aligned with the position where the turnover vehicle 5 is tilted, so that the tilted material 6 is directly guided into the receiving tank 101.
