Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace equipment technology, and in particular to a special feeding and discharging device for a vacuum furnace. Background Technology

[0002] A vacuum furnace is a device that performs high-temperature heating treatment in a closed environment. It is widely used in the heat treatment of metallic materials, especially in high-temperature quenching, annealing, tempering, and precision alloy manufacturing. By establishing a vacuum environment inside the furnace, oxidation reactions between the material and oxygen during heating can be effectively prevented, thus ensuring the surface quality, mechanical properties, and dimensional stability of the workpiece. As a key piece of equipment in the high-temperature quenching process, its feeding and discharging methods directly affect production efficiency, operational safety, and product consistency. Especially under complex conditions such as high temperature, high vacuum, and rapid cooling, the operational stability and control precision of the feeding and discharging device are particularly crucial.

[0003] Existing feeding and discharging systems face prominent problems in actual operation, such as inconvenience, low efficiency, and unstable quality. For example, utility model patent CN 217083270 U discloses a feeding and discharging system for a tunnel vacuum furnace in boron nitride production, including a base, a vacuum furnace body, a sealing component, a drive track, and a feeding component. This device uses a hydraulic cylinder to drive the track plate to rise and align with the drive track, realizing automatic feeding and discharging functions, and has the advantages of simple and smooth operation, saving time and labor, and requiring no manual intervention. However, in practical applications, it has been found that when the system performs the unloading operation, it adopts a sliding unloading method from a height. Although a buffer structure is set at the end position, due to the large weight of the sagger itself and the fact that it is filled with powder, there is still a large impact force during the unloading process, which can easily cause collision damage to the powder sagger, thereby affecting the stability of subsequent processes and the product qualification rate.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a dedicated feeding and discharging device for vacuum furnaces. This device should effectively solve the problem of sagger damage during the feeding process in existing systems, improve the stability and safety of the feeding and discharging process, significantly increase production efficiency and product consistency, while reducing operational complexity and maintenance costs, and better meet the demands of modern industry for a high-precision, high-efficiency, and high-safety production environment. Utility Model Content

[0005] The purpose of this utility model is to provide a special feeding and discharging device for vacuum furnaces, which solves the problem that when the material is discharged from a height, even though a buffer structure is set at the end point, there is still a large impact force during the discharge process due to the large weight of the sagger and the fact that it is filled with powder. This can easily cause collision damage to the powder sagger, thereby affecting the stability of subsequent processes and the product qualification rate.

[0006] To achieve the above objectives, this utility model provides a special feeding and discharging device for a vacuum furnace, a base and a vacuum furnace installed on top of the base. The vacuum furnace has a drive rail installed inside, and door panels are movably connected to both ends of the vacuum furnace through a vertical drive module.

[0007] Lifting modules are installed on both sides of the bottom of the base. A receiving frame is provided on one side of the top of the base, and a feeding plate is provided on the other side of the top. The bottom of the receiving frame and the bottom of the feeding plate are connected to the output end of the adjacent lifting module.

[0008] The top of the receiving frame is provided with a through groove, and a receiving plate is slidably connected inside the through groove. One side of the receiving plate is connected to one end of the receiving frame through a receiving push structure.

[0009] The top of the feeding plate is movably connected to a support plate via a horizontal drive structure. A push plate is provided on one side of the top of the support plate, and the push plate is connected to one end of the feeding plate via a feeding push structure.

[0010] The material receiving and pushing structure includes a second pushing cylinder installed at the center of one end of the material receiving frame. The output end of the second pushing cylinder is connected to the top of the material receiving plate through a fixed plate.

[0011] The top of each feeding plate is provided with a sliding groove. The horizontal drive structure includes a lead screw and a sliding block rotatably connected inside the sliding groove. The sliding block is threadedly engaged with the lead screw, and the top of the sliding block is connected to the bottom of the bearing plate. A vertical plate is connected to one side of the top of the feeding plate, and a drive motor that engages with the lead screw is installed at the bottom of one side of the vertical plate.

[0012] The two inner walls of the through groove are provided with movable grooves, and both sides of the receiving plate are slidably engaged with the movable grooves.

[0013] The feeding and pushing structure includes a pushing cylinder installed on one side of the vertical plate, and the output end of the pushing cylinder is connected to one side of the pushing plate.

[0014] Two guide rods are fixedly connected to one side of the push plate, and one end of each guide rod slides through the upright plate.

[0015] This utility model discloses a special feeding and discharging device for a vacuum furnace. Through the combined use of a lifting module and a horizontal drive structure, it achieves a smooth transition of the powder sagger during the process of entering and exiting the vacuum furnace. This avoids the problem of excessive impact force caused by sliding material from a height in traditional systems, effectively reduces the risk of collision damage to the powder sagger, and improves the product qualification rate.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a special feeding and discharging device for a vacuum furnace in this embodiment includes a base 1 and a vacuum furnace 4 installed on the top of the base 1. A drive rail 6 is installed inside the vacuum furnace 4, and door panels 3 are movably connected to the openings at both ends of the vacuum furnace 4 through a vertical drive module.

[0026] Lifting modules 7 are installed on both sides of the bottom of the base 1. A receiving frame 2 is provided on one side of the top of the base 1, and a feeding plate 5 is provided on the other side of the top. The bottom of the receiving frame 2 and the bottom of the feeding plate 5 are connected to the output end of the adjacent lifting module 7.

[0027] The top of the receiving frame 2 is provided with a through groove 16, and a receiving plate 18 is slidably connected inside the through groove 16. One side of the receiving plate 18 is connected to one end of the receiving frame 2 through a receiving push structure.

[0028] The top of the feeding plate 5 is movably connected to the support plate 12 via a horizontal drive structure. A push plate 11 is provided on one side of the top of the support plate 12. The push plate 11 is connected to one end of the feeding plate 5 via a feeding push structure.

[0029] During feeding, the powder sagger is first placed on top of the support plate 12. The feeding plate 5 is raised by the lifting module 7, causing the support plate 12 and the powder sagger to rise synchronously to the same height as the drive rail 6. Then, the horizontal drive structure moves one end of the support plate 12 close to the end of the drive rail 6. Finally, the feeding push structure pushes the powder sagger to the top position of the drive rail 6. After processing, during unloading, the receiving frame 2 is raised by the lifting module 7 to the same height as the drive rail 6. The receiving push structure moves the receiving plate 18 to the end of the drive rail 6. The drive rail 6 moves the powder sagger to the top of the receiving plate 18. Then, the receiving push structure brings the receiving plate 18 back to its original position. Finally, the lifting module 7 lowers the receiving frame 2 to the top of the base 1. During this process, the door panel 3 is opened by the vertical drive module to ensure unobstructed access to the inlet and outlet.

[0030] Example 2

[0031] Please see Figure 1-5 As shown in this embodiment, a special feeding and discharging device for a vacuum furnace includes a feeding and pushing structure comprising a second pushing cylinder 20 installed at the center of one end of a feeding frame 2. The output end of the second pushing cylinder 20 is connected to the top of a feeding plate 18 via a fixing plate 19. Specifically, the design of the feeding and pushing structure including the second pushing cylinder 20 installed at the center of one end of the feeding frame 2, with its output end connected to the top of the feeding plate 18 via the fixing plate 19, allows the second pushing cylinder 20 to precisely control the feeding and discharging movements of the feeding plate 18 during the feeding process. This design ensures that the feeding plate 18 can move smoothly between the drive rail 6 and the feeding frame 2, reducing the impact and collision risks of the powder sagger during transfer, and achieving the effect of improving operational stability and safety.

[0032] Both inner walls of the through groove 16 are provided with movable grooves 17, and both sides of the receiving plate 18 slide in engagement with the movable grooves 17. Specifically, the sliding engagement between the movable grooves 17 on the two inner walls of the through groove 16 and the sides of the receiving plate 18 ensures smooth sliding of the receiving plate 18 within the through groove 16. This design not only enhances the movement stability of the receiving plate 18 but also prevents it from shifting or jamming during operation, improving the overall reliability and durability of the equipment, and achieving the effect of extending service life and reducing maintenance costs.

[0033] Example 3

[0034] Please see Figure 1-5 As shown in this embodiment, a special feeding and discharging device for a vacuum furnace has a sliding groove 14 on the top of the feeding plate 5. The horizontal drive structure includes a lead screw 15 and a sliding block rotatably connected inside the sliding groove 14. The sliding block is threadedly engaged with the lead screw 15, and the top of the sliding block is connected to the bottom of the support plate 12. A vertical plate 10 is connected to one side of the top of the feeding plate 5, and a drive motor 13 cooperating with the lead screw 15 is installed at the bottom of one side of the vertical plate 10. Specifically, the horizontal drive structure composed of the sliding groove 14, lead screw 15, and sliding block on the top of the feeding plate 5, and the drive motor 13 installed on one side of the vertical plate 10, work together to drive the lead screw 15 to rotate during feeding, causing the sliding block to move the support plate 12 along the sliding groove 14 to the position of the drive track 6. This design achieves precise positioning and smooth movement of the support plate 12, avoiding the positional deviation problem caused by manual adjustment in traditional systems, improving the accuracy and efficiency of material transmission, and achieving the effect of improving production efficiency and product quality consistency.

[0035] The feeding and pushing structure includes a pushing cylinder 9 mounted on one side of the vertical plate 10. The output end of the pushing cylinder 9 is connected to one side of the pushing plate 11. Specifically, the design of the pushing cylinder 9 mounted on one side of the vertical plate 10 and connected to one side of the pushing plate 11 allows the pushing cylinder 9 to accurately push the powder cassette from the support plate 12 to the drive track 6 during the feeding process. This design ensures the smoothness and accuracy of material transfer, reduces errors caused by manual intervention, and improves operational safety and efficiency, thereby enhancing the level of production automation and product qualification rate.

[0036] Two guide rods 8 are fixedly connected to one side of the push plate 11. One end of each guide rod 8 slides through the vertical plate 10. Specifically, the design of the two guide rods 8 fixed to one side of the push plate 11, with one end sliding through the vertical plate 10, provides additional guiding support during the pushing of the powder sagger, ensuring that the push plate 11 moves smoothly in a straight line. This not only enhances the stability of the pushing process but also effectively prevents the push plate 11 from tilting or deviating from the track during operation, further improving the accuracy and safety of material transfer, and achieving the effect of optimizing the operation process and ensuring the long-term stable operation of the equipment.

[0037] This solution includes the following workflow:

[0038] In actual operation, during the feeding process, the powder sagger is first placed on top of the support plate 12. The lifting module 7 is activated to raise the feeding plate 5 to the same height as the drive rail 6. Then, the drive motor 13 drives the lead screw 15 to rotate, causing the sliding block to move the support plate 12 forward along the sliding groove 14 to a position close to the end of the drive rail 6. Next, the cylinder 9 is activated to push the push plate 11 forward. With the guidance of the guide rod 8, the powder sagger is smoothly pushed onto the drive rail 6, completing the feeding process. During the unloading operation, the lifting module 7 raises the receiving frame 2 to the same height as the drive rail 6. The cylinder 20 is activated to push the receiving plate 18 to slide along the moving groove 17 in the through groove 16 to the end of the drive rail 6. After the drive rail 6 delivers the processed powder sagger to the top of the receiving plate 18, the cylinder 20 is activated in the opposite direction to bring the receiving plate 18 back to its original position. Then, the lifting module 7 lowers the receiving frame 2 to the top of the base 1, completing the entire unloading process. Throughout the entire feeding and discharging process, the door panel 3 is controlled by the vertical drive module to ensure that the inlet and outlet of the vacuum furnace 4 are unobstructed.

[0039] Based on the above complete structural design, the equipment brings the following detailed beneficial effects: First, by combining the pushing cylinder 9 with the pushing plate 11 and guide rod 8, stable pushing of the powder sagger is achieved during the feeding process, avoiding sagger tilting or jamming caused by unstable pushing, thus improving feeding accuracy and automation; Second, the horizontal drive structure composed of sliding groove 14, lead screw 15, sliding block, and drive motor 13 provides precise translation control for the bearing plate 12, effectively improving the stability and repeatability of material conveying, thereby significantly improving production efficiency and product consistency; Third, the receiving plate 18 is driven by the pushing cylinder 20, and... The sliding fit between the sliding groove 17 and the inner wall of the through groove 16 makes the material handling process more stable and reliable, reduces the risk of collision between the sagger and the equipment, and further ensures the safety of the material. Fourth, the lifting module 7 controls the height adjustment of the receiving frame 2 and the feeding plate 5 respectively, so that the feeding and discharging operations are always aligned with the height of the drive track 6, avoiding the problem of material falling or jamming caused by height deviation in traditional systems, and improving the adaptability and operational stability of the system. Fifth, the door plate 3 is controlled to open and close through the vertical drive module, realizing automatic control of the furnace inlet and outlet, which not only improves operational safety, but also enhances the overall system's airtightness and vacuum environment maintenance capabilities. In summary, this special feeding and discharging equipment for vacuum furnaces, through multi-module collaborative design, solves the problems of sagger susceptibility to impact damage, complex operation, and low efficiency in existing technologies, significantly improving the stability, safety, and automation level of the feeding and discharging process, and meeting the actual needs of modern industry for a high-precision, high-efficiency, and high-reliability production environment.
