Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-temperature sintering box technology, specifically a high-temperature sintering box. Background Technology
[0002] Sintering is the process of transforming powdered materials into a dense body, a traditional technological process. This process has long been used to produce ceramics, powder metallurgy, refractories, and ultra-high temperature materials. Generally, after powder is shaped, the dense body obtained through sintering is a polycrystalline material, whose microstructure consists of crystals, glass, and pores. The sintering process directly affects the grain size, pore size, and grain boundary shape and distribution in the microstructure, thus affecting the material's properties. Macroscopic definition: At high temperatures (not exceeding the melting point), the solid particles of a ceramic green body bond together, grains grow, and voids (pores) and grain boundaries gradually decrease. Through mass transfer, the overall volume shrinks, density increases, and finally, a dense polycrystalline sintered body with a certain microstructure is formed. This phenomenon is called sintering. Microscopic definition: In a solid state, molecules (or atoms) attract each other, and heating allows these particles to gain sufficient energy for migration.
[0003] In existing technologies, after sintering samples in a high-temperature sintering chamber, the temperature of the sample and the sintering chamber is very high, and the sample is located inside the sintering chamber. When workers take out the sample, they are very likely to burn their arms, resulting in low safety. Therefore, we have introduced a high-temperature sintering chamber. Utility Model Content
[0004] The purpose of this invention is to provide a high-temperature sintering chamber that can prevent workers from being burned by high temperatures when taking out sintered samples, thus improving safety and having a high degree of automation, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-temperature sintering box includes a sintering box body, a sintering chamber on one side of the sintering box body, a door rotatably connected to one side of the sintering chamber via a movable connector, a locking buckle on the other side of the door, a movable plate on the lower side of the sintering chamber, and circular grooves on both sides of the sintering box body located on the movable plate. A pushing mechanism that can automatically push out the movable plate is provided in the circular grooves. A rectangular opening is provided in the middle of the upper part of the movable plate, and a rotating shaft is rotatably provided on the side of the rectangular opening near the sintering chamber. A support plate is fixedly provided on the shaft wall.
[0007] Furthermore, the pushing mechanism includes a movable rod and a push plate. The push plate is fixedly disposed on the front side of the movable plate, and the movable rod is slidably disposed in the circular groove. One end of the movable rod extends to the outside of the circular groove and is fixedly connected to the push plate. A spring is fixedly disposed at one end of the movable rod located in the circular groove, and the other end of the spring is fixedly connected to the bottom of the circular groove.
[0008] Furthermore, the wall of the circular groove is provided with an anti-detachment groove, and an anti-detachment block is slidably provided in the anti-detachment groove. One side of the anti-detachment block extends to the outside of the anti-detachment groove and is fixedly connected to the movable rod.
[0009] Furthermore, a limiting frame is fixedly provided at the upper end of the movable plate, and the position of the limiting frame corresponds to that of the rectangular opening.
[0010] Furthermore, the spring is always in a compressed state.
[0011] Furthermore, a roller is rotatably provided on the front side of the push plate near the movable connector.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This high-temperature sintering chamber, equipped with a door, sintering chamber, sintering chamber body, limiting frame, movable plate, push plate, rollers, tray, spring, anti-detachment block, movable rod, and rotating shaft, operates as follows: After the sample inside the sintering chamber is sintered, the door is opened. When the door is halfway open, the external transfer box is moved under the movable plate. The spring pushes the movable rod, which in turn pushes the push plate. The push plate moves the movable plate to the outside of the sintering chamber. At this point, the tray is no longer supported by the bottom of the sintering chamber, and one end of the tray rotates downwards. The sintered sample slides from the tray into the transfer box. When the door is closed, the inner wall of the door pushes the push plate into the sintering chamber via rollers. The push plate moves the movable plate into the sintering chamber, and the lower opening of the sintering chamber pushes the tray upwards to a horizontal position. This prevents workers from being burned by the high temperature when removing the sintered sample, improving safety and demonstrating a high degree of automation. Attached Figure Description

The spring 9 is always in a compressed state. A roller 7 is rotatably mounted on the front side of the push plate 6 near the movable connecting part. The roller 7 can reduce the friction between the door 1 and the push plate 6, making it easier for the door 1 to push the push plate 6.
[0023] The wall of the circular groove is provided with an anti-detachment groove, and an anti-detachment block 10 is slidably provided in the anti-detachment groove. One side of the anti-detachment block 10 extends to the outside of the anti-detachment groove and is fixedly connected to the movable rod 11. The anti-detachment block 10 can limit the movable rod 11 and prevent the movable rod 11 from detaching from the circular groove.
[0024] After the sample in the sintering chamber body 3 is sintered, the chamber door 1 is opened. When the chamber door 1 is opened halfway, the external transfer box is moved to below the movable plate 5. The spring 9 pushes the movable rod 11, the movable rod 1 pushes the push plate 6, and the push plate 6 moves the movable plate 5 to the outside of the sintering chamber 2. At this time, the tray 8 is no longer supported by the bottom of the sintering chamber 2, and one end of the tray 8 rotates downward. The sintered sample slides from the tray 8 into the transfer box. When the chamber door 1 is closed, the inner wall of the chamber door 1 pushes the push plate 6 into the sintering chamber 2 through the roller 7. The push plate 6 moves the movable plate 5 into the sintering chamber 2. The lower opening of the sintering chamber 2 pushes the tray 8 upward to a horizontal state, which can prevent the staff from being burned by high temperature when taking out the sintered sample, improve safety, and has a high degree of automation.
