Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of hot pressing and sintering furnaces, and in particular, to a hot pressing and sintering furnace for processing ceramic products. Background Art

[0002] Ceramics are a type of solid material made from inorganic non-metallic materials through high-temperature sintering and other processes. They have rich varieties, unique properties and a wide range of application markets. When preparing ceramics, a hot pressing sintering furnace is usually used. Ceramic powder is placed in the furnace body and heated by the heating wire in the furnace body to reach the critical temperature. After heating, pressure is applied to the powder through a hydraulic system to cause the ceramic powder to melt, diffuse and rearrange under high temperature and high pressure, thereby achieving densification sintering to form solid ceramic products.

[0003] When placing ceramic powder into the furnace body, the powder is usually placed into the mold first, and then the mold is placed into the furnace body, so that the powder can be restricted to a certain extent. Then, when pressurization is required after high-temperature heating is completed, the pressing plate can fall directly into the mold to pressurize the ceramic powder inside the mold, which is relatively targeted.

[0004] Existing molds are usually detachably installed inside the furnace body, so that the mold can be taken out when the ceramic powder is placed in the mold, avoiding the inner wall of the furnace body from obstructing the hands of the staff when placing the ceramic powder in the furnace body. At the same time, after sintering is completed, the mold is also taken out of the furnace body for subsequent processing.

[0005] When placing and taking out the mold, the staff usually takes it manually. Due to the high temperature after sintering, the staff needs to wear heat-insulating gloves to take it out, or clamp the mold with a clamp to take it out. Both methods require manual taking, which is more troublesome. Moreover, when taking it out, although with the help of tools and gloves, there is still a risk of burns when the staff's arms are inserted into the furnace to take it out. Summary of the Invention

[0024] like Figures 1 to 6 As shown, it shows a hot pressing sintering furnace for processing ceramic products in one embodiment of the present disclosure, including a furnace body 1, a placement rack 2 is installed in the furnace body 1, a furnace door 3 is hingedly installed on the side of the furnace body 1, and also includes a conveying rack 4, a support assembly and a retracting assembly. There are two conveying racks 4, both of which are arranged on the side of the furnace body 1 through the conveying assembly, and a clamping assembly is provided on the top of the conveying rack 4. The support assembly is arranged on the side of the furnace body 1, and is used to support the conveying assembly and the mold 5 for holding ceramic powder. The retracting assembly is arranged on the furnace body 1, and is used to retract the conveying assembly and the conveying rack 4 after the ceramic powder is placed in the furnace body 1.

[0025] like Figure 2As shown, when holding ceramic powder, the conveying assembly is first supported by the support assembly, and the mold 5 is placed at the same time. The conveying assembly includes a support cover 6, a driving screw 8, a first motor 10, a sliding rod 11 and a connecting rod 12. Support covers 6 are rotatably installed on both sides of the furnace body 1 through a rotating shaft 7. The driving screw 8 is rotatably installed in one of the support covers 6, and a moving block 9 with threaded matching is passed through the driving screw 8. One of the conveying racks 4 is fixedly installed on the moving block 9. The first motor 10 is installed on the support cover 6, and the output end of the first motor 10 is coaxially connected to the driving screw 8. The sliding rod 11 is fixedly installed on the other support cover 6, and a slider 29 is slidably installed on the sliding rod 11. Another conveying rack 4 is fixedly installed on the slider 29. A connecting rod 12 is fixedly installed on the side of the support cover 6, and the support assembly includes a first electric cylinder 13, a support frame 14 and a stabilizing assembly. Two first electric cylinders 13 are provided, and the two first electric cylinders 13 are both installed on the side of the furnace body 1. The support frame 14 is set to be U-shaped, and the bottom end of the support frame 14 is fixedly connected to the output ends of the two first electric cylinders 13. The stabilizing assembly is arranged on the support frame 14, and the stabilizing assembly includes a stabilizing rod 15, a slide rail 16 and an electromagnet 17. Stabilizing rods 15 are slidably installed on both sides of the support frame 14, and slide rails 16 are fixedly installed on both sides of the support frame 14, and the bottom end of the stabilizing rod 15 is slidably installed in the slide groove of the slide rail 16 through the slide rod. There are two electromagnets 17, and the two electromagnets 17 are fixedly installed on both sides of the two stabilizing rods 15.

[0026] Specifically, the first electric cylinder 13 is started, and the output end of the first electric cylinder 13 drives the support frame 14 to move upward. At this time, the support cover 6 is in a horizontal position and the furnace door 3 is opened. The stabilizing rod 15 is pulled on the slide rail 16 to make the two stabilizing rods 15 move relative to each other, and the electromagnet 17 is started. The side surfaces of the two stabilizing rods 15 are fitted together under the attraction of the two electromagnets 17, and then the mold 5 is placed on the top of the two stabilizing rods 15. At this time, the top of the support frame 14 contacts the bottom ends of the two support covers 6, so that the two support covers 6 can be supported. At this time, the furnace door 3 is in a horizontally opened state and is located in the middle groove of the support frame 14.

[0027] like Figure 4As shown, after placement, the mold 5 is clamped by a clamping assembly, which includes a protective cover 18, a second electric cylinder 19 and a clamping ring 20. The top ends of the two conveyor racks 4 are detachably installed with a protective cover 18. Two second electric cylinders 19 are provided, and the two second electric cylinders 19 are respectively installed on the two protective covers 18. The output end of the second electric cylinder 19 is fixedly installed with a clamping ring 20. The curvature of the inner wall of the clamping ring 20 is consistent with the curvature of the outer wall of the mold 5, and the inner wall of the clamping ring 20 is installed with an anti-slip pad. Specifically, the second electric cylinder 19 is started, and the output end of the second electric cylinder 19 drives the clamping ring 20 to move toward the mold 5, so that the clamping ring 20 fits the mold 5, thereby clamping and fixing the mold 5.

[0028] like Figure 3 As shown, after the clamping ring 20 completes clamping the mold 5, the first motor 10 is started, and the output end of the first motor 10 drives the driving screw 8 to rotate in the support cover 6, so that the moving block 9 moves backward on the driving screw 8. It should be added that a fixed rod 28 is fixedly installed between the two conveyor racks 4. Driven by the fixed rod 28, the conveyor rack 4 on the other side moves synchronously on the sliding rod 11 under the sliding of the slider 29, thereby driving the two conveyor racks 4 to move forward, and then the clamped mold 5 is moved to the placement rack 2 in the furnace body 1. Because the top of the stabilizing rod 15 and the top of the placement rack 2 are at the same horizontal position, the mold 5 can be directly placed on the placement rack 2 when it contacts the placement rack 2. The moving block 9 stops when it moves to the sidemost edge of the support cover 6. At this time, the mold 5 is located directly below the pressurizing assembly in the furnace body 1. After placement is completed, the first motor 10 is started in reverse again to drive the conveyor rack 4 to move out of the furnace body 1.

[0029] like Figure 5 As shown, after the conveyor frame 4 moves out of the furnace body 1, the solenoid valve is controlled to cancel the magnetism, and then the position of the sliding stabilizing rod 15 on the slide rail 16 is slid to move to both sides, and then the first electric cylinder 13 is started. The first electric cylinder 13 drives the support frame 14 to move downward, so that the top end of the support frame 14 is separated from the bottom end of the support cover 6, and finally the support cover 6 is lifted by the retractable assembly so that the furnace door 3 can be closed. The retractable assembly includes a second motor 21, a driving gear ring 22, a driving gear 23 and a pulling assembly. The second motor 21 is installed on the side of the furnace body 1 through the mounting frame The driving gear ring 22 is fixedly mounted on one of the rotating shafts 7, the driving gear 23 is coaxially connected to the output end of the second motor 21, and the driving gear ring 22 is meshed with the driving gear 23. The pulling assembly is arranged at the top of the furnace body 1, and the pulling assembly includes a mounting block 24, a pull rope 25, a pull hook 26 and a pulling frame 27. Two mounting blocks 24 are fixedly mounted on the top of the furnace body 1, and a pull rope 25 is fixedly mounted on the side of the mounting block 24. The pull hook 26 is fixedly mounted on the other end of the pull rope 25, and two pulling frames 27 are fixedly mounted on the side of the connecting rod 12.

[0030] Specifically, the second motor 21 is started, and the output end of the second motor 21 drives the driving gear 23 to rotate, and the driving gear 23 drives the driving gear ring 22 meshing with it to rotate, and the driving gear ring 22 drives one of the rotating shafts 7 to rotate, thereby driving one of the support covers 6 to rotate, and under the connection of the connecting rod 12, drives the other support cover 6 to rotate on the side of the furnace body 1, so that the other ends of the two support covers 6 are rotated to the oblique upper part of the furnace body 1, and the conveying frame 4 and the clamping ring 20 and the first electric cylinder 13 are rotated synchronously to the top of the furnace body 1, and the hook 26 is hung on the pulling frame 27 to further fix them. At this time, the furnace door 3 is closed, and the furnace body 1 is started to pressurize and sinter the ceramic powder in the mold 5.

[0031] Working principle: When hot pressing and sintering ceramic powder, first open the furnace door 3 and the support cover 6 is in a horizontal position, start the first electric cylinder 13, and the output end of the first electric cylinder 13 drives the support frame 14 to move up to fit the bottom end of the support cover 6, and then pull the position of the stabilizing rod 15 on the slide rail 16 to make the two stabilizing rods 15 move relative to each other, and start the electromagnet 17. Under the attraction of the two electromagnets 17, the side surfaces of the two stabilizing rods 15 are fit together, and then the mold 5 is placed on the top of the two stabilizing rods 15. After placement, the two clamping rings 20 are located on both sides of the mold 5, and start the second electric cylinder 19. The output end of the second electric cylinder 19 drives the clamping ring 20 to move toward the mold 5, so that the clamping ring 20 fits the mold 5, thereby clamping and fixing the mold 5.

[0032] After the fixation is completed, the first motor 10 is started, and the output end of the first motor 10 drives the driving screw 8 to rotate in the support cover 6, so that the moving block 9 moves backward on the driving screw 8, and under the drive of the fixing rod 28, the conveying rack 4 on the other side moves synchronously on the sliding rod 11 under the sliding of the slider 29, thereby driving the two conveying racks 4 to move forward, and then the clamped mold 5 is moved to the placement rack 2 in the furnace body 1. After placement is completed, the first motor 10 is started in the opposite direction again to drive the conveying rack 4 to move out of the furnace body 1, and then the second motor 21 is started. The output end of the second motor 21 drives the driving gear 23 to rotate, and the driving gear 23 drives the driving gear ring 22 meshing with it to rotate, and the driving gear ring 22 drives one of the rotating shafts 7 to rotate, thereby driving one of the support covers 6 to rotate, and under the connection of the connecting rod 12, drives the other support cover 6 to rotate on the side of the furnace body 1, so that the other end of the two support covers 6 rotates to the oblique upper part of the furnace body 1, and then the draw hook 26 is hung on the pulling rack 27 to further fix it.

[0033] like Figure 6As shown, the furnace door 3 is then closed, and the furnace body 1 is started to pressurize and sinter the ceramic powder in the mold 5. An electric heating wire is installed in the furnace body 1, which can heat the interior, thereby heating the ceramic powder in the mold 5 at high temperature. After heating, the ceramic powder in the mold 5 is pressurized by the hydraulic cylinder at the top of the furnace body 1, and the mold 5 is made of high-temperature resistant material.

[0034] After the pressure sintering is completed, the furnace door 3 is opened, the support cover 6 is rotated in the opposite direction to the horizontal position, and then the clamping ring 20 is moved into the furnace body 1 to clamp the mold 5. The protective cover 18 can protect the second electric cylinder 19 and block the high temperature. After clamping the mold 5, start the first motor 10 to move it out. Before that, start the first electric cylinder 13 to move the support frame 14 up to fit the bottom end of the support cover 6 and continue to pull the stabilizing rod 15 so that the sides of the two stabilizing rods 15 fit together, and place the moved mold 5 on the top of the stabilizing rod 15. It should be added that the stabilizing rod 15 and the clamping ring 20 are both made of high-temperature resistant materials.
