[0003] Heat treatment cylinders are typically designed to be relatively enclosed, with only one openable end cap for feeding and unloading. While this enclosed structure helps reduce heat loss and improve energy efficiency during the heating and holding stages, it becomes a major factor hindering cooling speed during the cooling stage. The relatively enclosed heat treatment cylinder is not conducive to air convection, and the residual heat from the heating elements further hinders the rapid dissipation of heat. To address these issues, a heat treatment device with rapid cooling capability is needed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] according to Figure 1-4 As shown: This utility model provides a heat treatment device with rapid cooling function: including a support 1, and a heat treatment cylinder 3 is fixedly connected to the inner wall of the support 1 by a support rod 2;
[0023] The heat treatment cylinder 3 has an open structure at both the top and bottom, and an upper sealing cover 6 is provided at the upper end of the heat treatment cylinder 3, while a lower sealing cover 4 is provided at the lower end of the heat treatment cylinder 3; for example Figure 4 As shown, sealing grooves 16 are provided at both the upper and lower ends of the heat treatment cylinder 3, and sealing blocks 15 inserted into the sealing grooves 16 are fixedly connected to the upper sealing cover 6 and the lower sealing cover 4 respectively. The sealing grooves 16 and sealing blocks 15 can increase the sealing performance of the connection between the upper sealing cover 6, the lower sealing cover 4 and the heat treatment cylinder 3.
[0024] A heating block 12 located inside the heat treatment cylinder 3 is provided on the lower sealing cover 4, and a placement grid frame 13 located inside the heat treatment cylinder 3 is fixedly connected to the lower part of the upper sealing cover 6 via a connecting rod 14; a fixing cylinder 5 is fixedly provided inside the bracket 1, and an opening and closing component that can simultaneously control the sliding of the upper sealing cover 6 and the lower sealing cover 4 is provided inside the fixing cylinder 5.
[0025] like Figure 2 As shown, the opening and closing assembly includes a rotary motor 8, a bidirectional lead screw 10, and sliders 9. The rotary motor 8 is mounted on the bracket 1. The bidirectional lead screw 10 is rotatably mounted inside the fixed cylinder 5, and the working end of the bidirectional lead screw 10 is fixedly connected to the rotary motor 8. Two sliders 9 are provided, each threadedly connected to a corresponding position on the bidirectional lead screw 10. A guide groove is provided on the outer wall of the fixed cylinder 5. Two limiting rods 11 are respectively fixedly connected to the two sliders 9 within the guide groove, and the two limiting rods 11 are respectively fixedly connected to the lower sealing cover 4 and the upper sealing cover 6. The guide groove and the limiting rods 11 restrict the rotation of the sliders 9, thereby converting the rotation of the bidirectional lead screw 10 into the movement of the sliders 9, which in turn drives the upper sealing cover 6 and the lower sealing cover 4 to slide. It also includes:
[0026] The system includes a cooling fan 7 and cooling holes 17. A connecting groove 21 is provided inside the upper sealing cover 6, and several cooling holes 17 communicating with the connecting groove 21 are provided at the bottom of the upper sealing cover 6. The cooling fan 7 is mounted on the bracket 1, and its working pipe is connected to the connecting groove 21. The working pipe of the cooling fan 7 is a sufficiently long flexible hose to ensure normal communication between the connecting groove 21 and the cooling fan 7 when the upper sealing cover 6 slides up and down. A sealing component is provided inside the connecting groove 21 to seal the cooling holes 17.
[0027] like Figure 4 As shown, the sealing assembly includes an adjusting motor 19, an adjusting screw 18, and a sealing plate 20. The adjusting motor 19 is mounted on the upper sealing cover 6. The adjusting screw 18 is rotatably mounted in the connecting groove 21 and is fixedly connected to the output shaft of the adjusting motor 19. The sealing plate 20 is threadedly connected to the adjusting screw 18 and seals the cooling holes 17. The sealing plate 20 prevents the high-temperature gas in the heat treatment cylinder 3 from affecting the cooling fan 7 and its working pipeline through the cooling holes 17 and the connecting groove 21. The cooling holes 17 are evenly distributed at the bottom of the sealing plate 20. A limiting post 22 is fixedly installed in the connecting groove 21, and the sealing plate 20 slides on the limiting post 22. The limiting post 22 restricts the rotation of the sealing plate 20, thereby converting the rotation of the adjusting screw 18 into the sliding of the sealing plate 20.
[0028] The principle of this utility model
[0029] like Figure 2 , 3 As shown, during normal use of this application, the rotating motor 8 is started first, and the two sliders 9 are used to drive the upper sealing cover 6 and the lower sealing cover 4 to separate from the heat treatment cylinder 3. The placement frame 13 also slides out from the heat treatment cylinder 3, and the metal material can be placed directly on the placement frame 13. The rotating motor 8 is reversed so that the upper sealing cover 6 and the lower sealing cover 4 seal the upper and lower ends of the heat treatment cylinder 3 respectively, forming a relatively closed structure. The heating block 12 on the lower sealing cover 4 can be used to heat the metal material on the placement frame.
[0030] When heat treatment is complete and the heat treatment cylinder 3 needs to be cooled, such as... Figure 2As shown, the rotating motor 8 is started, causing the upper sealing cover 6 and the lower sealing cover 4 to separate from the heat treatment cylinder 3. At this time, both the upper and lower ends of the heat treatment cylinder 3 are opened. Then, the adjusting motor 19 is started, causing the sealing plate 20 to slide upward, releasing the seal on the cooling hole 17. The cooling fan 7 is started, supplying air to the placement frame 13 through the connecting groove 21 and the cooling hole 17. The air directly contacts the placement frame 13, thereby cooling the metal material on the placement frame 13. At the same time, the air can pass through the placement frame 13 and enter the heat treatment cylinder 3 to cool the heat treatment cylinder 3. Since both the upper and lower ends of the heat treatment cylinder 3 are open at this time, a good convection effect can be achieved, accelerating the cooling speed.
[0031] When both the upper sealing cover 6 and the lower sealing cover 4 are opened, as Figure 4 As shown, the upper sealing cover 6 moves the placement frame 13 upward via the connecting rod 14, enabling the metal material to be removed from the heat treatment cylinder 3. At the same time, the lower sealing cover 4 moves the heating block 12 downward away from the heat treatment cylinder 3, preventing the residual heat of the heating block 12 from affecting the cooling of the heat treatment cylinder 3 and improving the cooling rate.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
