Description

Technical Field

[0001] This utility model relates to the technical field of aging furnace structure, specifically to a low-temperature vacuum aging furnace. Background Technology

[0002] An aging furnace is one of the main pieces of equipment in the processing of metal workpieces. The metal workpieces are placed in the furnace, and the temperature in the furnace is set according to the actual situation, generally at room temperature or a higher temperature. The metal workpieces undergo a heat treatment process in which their size, properties, and shape change over time.

[0003] The operating process of aging furnaces varies depending on the actual situation, resulting in a variety of different aging furnaces. Some workpieces need to be processed in a low-temperature vacuum environment, but there are very few vacuum low-temperature aging furnaces on the market. Some existing aging furnaces are not convenient for loading and unloading materials due to the depth of the furnace body, and are also limited by the limited space inside the furnace. Therefore, a low-temperature vacuum aging furnace is proposed. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-4 The present invention relates to a low-temperature vacuum aging furnace, comprising a furnace body 1, with two partitions 2 detachably connected to the inner wall of the furnace body 1, and two support plates 3 provided on the top side wall of each partition 2. A rotating shaft 13 is rotatably connected to the middle of the side wall of the support plate 3 away from the partition 2, and a turntable 10 is detachably connected to the top of the rotating shaft 13. Four placement racks 4 are rotatably provided on the side wall of the turntable 10 away from the rotating shaft 13.

[0019] A rotating column 11 is rotatably connected to the top of the turntable 10 and the side wall opposite to the placement rack 4. The rotating column 11 is detachably connected to the middle of the bottom side wall of the placement rack 4. Supporting columns 12 are fixedly connected to the top of the turntable 10 and the four side walls of the rotating column 11. A ball bearing is rotatably connected to the top of the supporting column 12. The height of the supporting column 12 is the same as that of the rotating column 11. The ball bearing at the top of the supporting column 12 is attached to the bottom side wall of the placement rack 4. A slider 5 is fixedly connected to the bottom of the tray 3 and near the two side edges. A groove is opened on the top of the partition 2 and opposite to the slider 5. The slider 5 is slidably connected in the groove.

[0020] The technical advantages of this solution are as follows: When it is necessary to pick up or put down materials, first pull the pallet 3 out of the furnace body 1, then rotate the turntable 10 to adjust the corresponding placement rack 4 to a position facing the operator. After that, the operator takes down the processed workpiece and places the new workpiece on the placement rack 4. By rotating, the four placement racks 4 are gradually replaced. Because they can be rotated and adjusted, the convenience of operation is improved. At the same time, pulling out the pallet 3 provides sufficient space for the operator's operation, avoiding the limitation of the limited space in the furnace body 1 that affects the efficiency of picking up and putting down workpieces. In addition, the placement rack 4 and the rotating column 11 are detachably connected, so different sizes of placement racks 4 can be adjusted as needed to place workpieces of different sizes. It should be noted that the size of the replacement placement rack 4 should not affect its independent rotation, and the number should also be adjusted according to the size of the placement rack 4 to avoid movement interference.

[0021] A bottom groove 14 is provided on the bottom side wall of the furnace body 1. A cooling element 15 is detachably embedded in the bottom groove 14. A sealing plate 16 is embedded in the top opening of the bottom groove 14. The bottom side wall of the sealing plate 16 is fitted with the top side wall of the cooling element 15. A distribution box 6 is detachably connected to the side wall of the furnace body 1 near the top. The distribution box 6 is electrically connected to the cooling element 15 through wires. A tank 7 is provided on one side of the furnace body 1 and below the distribution box 6. The top of the tank 7 is inserted and fixedly connected to... A suction pipe 8 is connected, which has an L-shaped structure. One end of the suction pipe 8 is detachably connected to one side wall of the furnace body 1 and communicates with the inside of the furnace body 1. An exhaust pipe 9 is fixedly connected to the side wall of the tank body 7 away from the furnace body 1 and close to the bottom. A vacuum pump 17 is detachably connected inside the tank body 7. One end of the suction pipe 8 extending into the tank body 7 is detachably connected to the inlet of the vacuum pump 17, and one end of the exhaust pipe 9 is detachably connected to the outlet of the vacuum pump 17.

[0022] The technical effects of this solution are as follows: the power supply to the cooling chip 15 is provided through the distribution box 6, so that the cooling chip 15 can generate low temperature. The low temperature is transferred upward through the sealing plate 16 and finally fills the space inside the furnace body 1, thereby realizing the function of low temperature inside the furnace body 1. The cooling chip 15 adopts semiconductor refrigeration technology, which can reduce its installation space and increase the internal volume of the furnace body 1. Similarly, the power supply to the vacuum pump 17 is provided through the distribution box 6, so that the air inside the furnace body 1 can be extracted through the suction pipe 8 and finally discharged through the exhaust pipe 9, thereby creating a vacuum environment inside the furnace body 1. The combination of the above two achieves a vacuum low temperature processing environment.

[0023] Specifically, when using this utility model, first pull out the pallet 3, then place the workpieces to be processed sequentially on the placement rack 4. After the current placement rack 4 is filled, rotate the turntable 10 to replace the placement rack 4. Repeat this process until all placement racks 4 are filled with workpieces. Then, push the pallet 3 into the furnace body 1. Then, power is supplied to the vacuum pump 17 and the cooling element 15 through the distribution box 6. After the cooling element 15 is powered on and started, the low temperature generated will pass through the sealing plate 16 and gradually rise until the internal space of the furnace body 1 is filled, thus forming a low temperature environment. At the same time, the vacuum pump 17, which is powered on and started, will extract the air from the furnace body 1 through the suction pipe 8, thus forming a vacuum environment inside the furnace body 1. The two work together to form the vacuum low temperature environment required for processing. After processing is completed, stop supplying power to the vacuum pump 17 and the cooling element 15, then open the door, pull out the pallet 3, and replace the workpieces on the placement rack 4 with new workpieces to start the next round of processing.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
