Description

Technical Field

[0001] This utility model relates to the field of vacuum degreasing technology, and in particular to a vacuum degreasing treatment structure. Background Technology

[0002] Vacuum degreasing is a common process that removes grease, oxides, and other impurities from the surface of metal products to improve their surface quality and processing performance. The working principle of vacuum degreasing is to utilize high-temperature heating and gas extraction in a vacuum environment to evaporate or oxidize and decompose impurities on the surface of the metal product, thereby achieving the purpose of degreasing.

[0003] In existing commonly used vacuum degreasing processes, multiple metal parts are usually stacked together in multiple layers and placed into the furnace for degreasing. This can easily lead to obstruction of gas flow between the stacked metal parts, resulting in uneven volatilization of the processing grease and affecting the degreasing efficiency. In addition, since the parts need to be placed into the furnace before degreasing, the furnace shell will block the parts, thus affecting the operator's loading efficiency.

[0004] Therefore, it is necessary to propose a vacuum degreasing treatment structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vacuum degreasing structure to solve the problem mentioned in the background art that in the existing commonly used vacuum degreasing process, multiple metal parts are usually stacked together in multiple layers and placed in the furnace for degreasing. This can easily lead to obstruction of gas flow between the stacked metal parts, resulting in uneven volatilization of the processing grease and affecting the degreasing efficiency. In addition, since the parts need to be placed in the furnace before degreasing, the furnace shell will block the parts, thus affecting the operator's loading efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vacuum degreasing treatment structure includes a furnace body, a furnace door hinged to one end of the furnace body, and a support base disposed inside the furnace body;

[0008] The furnace body is provided with slide rails on opposite sides along the length direction, and the support base is slidably connected to the slide rails;

[0009] The support base has several slots along its width, and partitions are movably engaged in the slots.

[0010] The support base also has several through holes.

[0011] Preferably, each of the four apex corners of the support base is provided with a receiving cavity, and a pulley adapted to the slide rail is connected in the receiving cavity, with the pulley extending horizontally to the outside of the receiving cavity.

[0012] Preferably, a stopper is provided at one end of the furnace body away from the furnace door, and grooves adapted to the stopper are provided at both ends of the support base.

[0013] Preferably, the bottom of the partition is provided with a protrusion that matches the slot.

[0014] Preferably, the partition is a thermally conductive partition.

[0015] Preferably, the furnace body is provided with an air inlet, and a preheating pipe is connected to the air inlet.

[0017] Preferably, guide edges are also provided on opposite sides of the furnace body along the length direction, and the guide edges are located above the slide rail.

[0018] Preferably, both the support base and the partition are made of high-temperature resistant materials.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. A partition is installed on the support base so that metal parts can be placed in the space formed by two adjacent partitions. The partitions separate the parts, and the gap between the partitions and the parts, as well as the through holes on the support base, ensure uniform gas flow and prevent uneven grease evaporation from affecting the degreasing efficiency. Since the partitions are movably connected to the support base, the space between two adjacent partitions can be increased by removing the partitions, thereby accommodating parts of different sizes and expanding the applicability of this structure.

[0021] Second, by setting a slide rail inside the furnace body, the support base is slidably connected to the slide rail.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 1-3 As shown, this utility model embodiment provides a vacuum degreasing treatment structure, including a furnace body 10, a furnace door hinged to one end of the furnace body 10, and a support base 20 disposed inside the furnace body 10; the furnace body 10 has corresponding slide rails 30 on opposite sides along the length direction, and the support base 20 is slidably connected to the slide rails 30; the support base 20 has a plurality of slots 201 opened along its width direction, and a partition 40 is movably engaged on the slots 201; wherein, the support base 20 also has a plurality of first through holes 202 opened.

[0038] Specifically, such as Figure 5 As shown, the bottom of the partition 40 is provided with a protrusion 401 that matches the slot 201, so as to ensure the stable connection between the partition 40 and the support 20, and also to facilitate the installation and removal of the partition 40; both the support 20 and the partition 40 are made of high temperature resistant materials to ensure the service life of the support 20 and the partition 40.

[0039] It should be noted that the cross-sectional shape of the furnace body 10 can be circular or square, depending on the production requirements.

[0040] A partition 40 is provided on the support base 20, allowing the metal parts 90 to be placed in the space formed by two adjacent partitions. The partition 40 separates the parts, and the gap between the partition 40 and the metal parts 90, as well as the through holes on the support base 20, ensures uniform gas flow and prevents uneven grease evaporation from affecting degreasing efficiency. Since the partition 40 is movably connected to the support base 20, the space between two adjacent partitions can be increased by removing the partition 40, thereby accommodating parts of different sizes and expanding the applicability of this structure. By providing a slide rail 30 inside the furnace body 10, the support base 20 is slidably connected to the slide rail 30. During material feeding, the support base 20 can be slid out of the furnace body 10 in whole or in part, facilitating quick material feeding by operators and ensuring feeding efficiency.

[0041] Specifically, such as Figure 4 As shown, each of the four corners of the support base 20 has a receiving cavity 203. A pulley 50 adapted to the slide rail 30 is connected in the receiving cavity 203. Part of the pulley 50 extends horizontally to the outside of the receiving cavity 203, so that the pulley 50 can drive the entire support base 20 to slide on the slide rail 30.

[0042] To prevent the support base 20 from sliding into the furnace body 10 and colliding with it, a stopper 60 is provided at the end of the furnace body 10 away from the furnace door, and grooves 204 adapted to the stopper 60 are provided at both ends of the support base 20. When the support base 20 slides into the furnace body 10, the stopper 60 will be locked into the groove 204, thereby preventing the support base 20 from colliding with the furnace body 10.

[0043] In addition, in order to ensure that the metal part 90 is heated evenly, the partition 40 is a heat-conducting partition. By utilizing its heat conduction function to transfer heat, it can effectively prevent the significant temperature gradient caused by uneven heat distribution from causing the part to deform.

[0044] Furthermore, such as Figure 6 As shown, an air inlet is provided on the furnace body 10, and a preheating pipe 70 is connected to the air inlet. The gas entering the furnace body 10 can be preheated through the preheating pipe 70 to avoid temperature difference shock. In this embodiment, the preheating pipe 70 is located at the end of the furnace body 10 away from the furnace door.

[0045] Specifically, the preheating tube 70 is a spirally wound connecting tube, which allows the gas to be fully preheated.

[0046] In order to enable the support base 20 and the metal parts 90 above it to slide more smoothly, guide edges 80 are also provided on the opposite sides of the furnace body 10 along the length direction. The guide edges 80 are located above the slide rail 30 to protect the metal parts 90.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
