Technical Field
[0001] The utility model relates to the technical field of tempering furnaces, in particular to a spiral chamber of a tempering furnace. Background Art
[0002] A tempering furnace is a heat treatment device specially used for tempering metal materials. It heats the metal workpiece to a certain temperature, keeps it at this temperature for a period of time, and then slowly cools it to improve the performance and stability of the metal.
[0003] Especially in large-scale manufacturing fields such as workpiece production, in order to improve efficiency, a chamber is usually set up to automatically transport the furnace core of the tempering furnace. However, the existing chamber design is mostly linear. This structure is not convenient for flipping the parts during the process of transporting the furnace core, which makes it difficult for the internal parts to be heated evenly, thereby affecting the tempering effect. Therefore, the existing Chinese utility model patent disclosed by the publication number CN220099115U: a spiral chamber of a tempering furnace, the application sets a spiral chamber, and drives the tempering furnace core to move in a threaded transmission manner inside the spiral chamber, so that the rotating tempering furnace core drives a large number of parts to flip and move, so that a large number of parts can be mixed with each other during the flipping process, and each part is heated. The heating surface can be adjusted, thereby effectively increasing the total heating surface of a large number of parts, and a tempering furnace core with threaded transmission is provided, so that the tempering furnace core can drive the parts to move from the feed port to the discharge port. However, in this application, it is difficult to stably transport the workpieces accumulated in the furnace core to the discharge cooling pipe only by the spiral groove on the inner side of the spiral chamber. At the same time, due to the spiral transportation of the workpiece, the workpiece cannot continue to move after entering the discharge cooling pipe, so that some workpieces will be accumulated in the discharge cooling pipe, and the normal unloading of the workpieces after tempering cannot be guaranteed. In addition, the discharge cooling pipe is connected to the tempering furnace core, which will cause part of the heat inside the tempering furnace core to be discharged through the discharge cooling pipe, resulting in heat loss.

[0021] like Figure 2As shown, the screw feeder 7 and the rotating shaft 8 are both made of chromium-nickel alloy. A discharge channel 11 is provided at the lower end of the tempering furnace chamber 1. The discharge channel 11 is inclined at fifteen degrees and provided in the tempering furnace chamber 1. A sealing plate 12 is movably installed in the discharge channel 11. Through the opening of the discharge channel 11, the workpieces that have been tempered can be gravity discharged in cooperation with the screw feeder 7. The sealing plate 12 is a horizontal L-shaped structure. The sealing plate 12 is made of silicon brick. A slide groove 13 is provided on one side of the sealing plate 12. The transverse section of the slide groove 13 is T-shaped. A slider 14 is slidably installed in the slide groove 13. A fixed shaft 15 is fixedly installed at the center position of one side of the slider 14. The sealing plate 12 is inserted and installed in the discharge channel 11. The workpieces that have been tempered can be temporarily stored and collected into the collection box 9 after a certain amount of storage. At the same time, the sealing plate 12 can also close the discharge channel 11.
[0022] like Figure 2-Figure 3 As shown, one side of the collecting box 9 is fixedly mounted on one side of the tempering furnace chamber 1, and an exhaust fan 16 is fixedly mounted on one side of the top of the collecting box 9, and the exhaust fan 16 is electrically connected to an external controller through a cable. A cylinder 17 is also arranged on the top of the collecting box 9, and the upper end of the cylinder 17 is fixedly mounted on the bottom of the collecting box 9 through two fixed plates 18, and the output end of the cylinder 17 is fixedly connected to one side of the fixed shaft 15. With the help of the cooperation between the cylinder 17, the fixed shaft 15 and the slider 14, the sealing plate 12 can move obliquely in the unloading channel 11. The upper and lower ends of the pull-out box 10 are through-type through grooves, and the pull-out box 10 is inserted and installed in the collecting box 9, and a box door 19 is fixedly mounted on one side of the pull-out box 10. With the help of the setting of the pull-out box 10, the workpieces stored in the collecting box 9 can be pushed for unloading.
[0023] It should be noted that the utility model is a spiral chamber of a tempering furnace. When in use, the workpieces are dumped into the chamber 1 of the tempering furnace through the furnace door 3 in batches, and then the transmission mechanism and the heater 6 in the transmission box 4 are started by an external controller, so that the transmission mechanism in the transmission box 4 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the spiral feeder 7 to rotate, so that the workpieces can be slowly transported from one side to the other side in the chamber 1 of the tempering furnace, and the workpieces are heated and tempered during the transportation process, and the tempered workpieces will enter the unloading channel 11 for temporary storage;

Then, the output end of the cylinder 17 pulls the fixed shaft 15 and the slider 14 to move to one side, and then the slider 14 pulls the sealing plate 12 to move obliquely downward in the collection box 9 through the slide groove 13. Then, after the sealing plate 12 partially moves from the sealing plate 12 to the collection box 9, gravity causes the workpieces to enter the collection box 9 located on the inner side of the pull-out box 10 from the unloading channel 11. After the unloading of the current batch of workpieces is completed, the cylinder 17 is reset and the sealing plate 12 is pushed back into the unloading channel 11. When a certain amount of workpieces are stored in the collection box 9, a collection cart can be placed under the collection box 9, and the pull-out box 10 can be gradually pulled outward from the collection box 9 through the box door 19. Then, one side of the pull-out box 10 scrapes out the workpieces in the collection box 9 and causes the workpieces to fall into the collection cart.
