Description

Technical Field

[0001] This utility model relates to the field of vacuum sintering furnace technology, specifically a rapid cooling device for a large horizontal vacuum sintering furnace. Background Technology

[0002] A vacuum sintering furnace is a key heat treatment device that uses high-temperature heating in a vacuum or inert gas protected environment to achieve densification of powder or pressed materials. Its core principle is to use the vacuum environment to isolate oxygen, preventing the material from oxidizing or reacting with impurities at high temperatures. At the same time, by precisely controlling parameters such as temperature, pressure, and time, the sintering, diffusion bonding, or heat treatment of the material is achieved. Large horizontal vacuum sintering furnaces achieve densification of materials through a vacuum environment and high-temperature heating. The core function of the rapid cooling device in large horizontal vacuum sintering furnaces is to significantly improve cooling efficiency and shorten the production cycle through technologies such as chilled water circulation, inert gas pressurization, and material tray rotation, while ensuring the consistency of material properties.

[0003] Vacuum sintering furnaces of ordinary equipment lack dynamic heat preservation and adjustment structures, making it impossible to release heat quickly after sintering. Furthermore, the heat preservation layer of ordinary equipment is usually fixed and cannot be dynamically adjusted according to the needs of the sintering and cooling stages. During the sintering process, temperature fluctuations may occur due to insufficient heat preservation, and during cooling, the heat dissipation speed may be affected if the heat preservation layer is not removed in time. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a rapid cooling device for a large horizontal vacuum sintering furnace. This device has the advantage of improving the cooling efficiency of the vacuum sintering furnace and solves the problems of ordinary devices lacking a dynamic heat preservation and adjustment structure, which makes it impossible to quickly release heat after sintering. Furthermore, the heat preservation layer of ordinary devices is usually fixed and cannot be dynamically adjusted according to the needs of the sintering and cooling stages. During the sintering process, insufficient heat preservation may cause temperature fluctuations, and during cooling, the heat dissipation speed may be affected because the heat preservation layer is not removed in time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling device for a large horizontal vacuum sintering furnace, comprising a vacuum sintering furnace, a placement chamber, and a cooling device, wherein the placement chamber is opened on the left and right sides of the top of the vacuum sintering furnace, and the cooling device is fixedly connected to the inside of the placement chamber.

[0006] In a preferred embodiment of this invention, the cooling device includes an insulation layer, a lifting rod, an electric drive platform, a vacuum sealing device, and a mounting flange. The lifting rod is fixedly connected to the top of the insulation layer, and the vacuum sealing device is slidably connected to the surface of the lifting rod. The mounting flange is fixedly connected to the outer surface of the vacuum sealing device, and the electric drive platform is fixedly connected to the top of the mounting flange.

[0007] As a preferred embodiment of this invention, the top of the mounting flange is threaded with a plurality of fixing bolts at equal intervals, and the plurality of fixing bolts are threadedly connected to the bottom of the placement cavity.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problems of ordinary vacuum sintering furnaces lacking dynamic heat preservation and adjustment structures, failing to quickly release heat after sintering, and having fixed heat preservation layers that are usually fixed and cannot be dynamically adjusted according to the needs of sintering and cooling stages. This can lead to temperature fluctuations during sintering due to insufficient heat preservation, and the inability to remove heat in time during cooling.

[0009] 2. By setting up a cooling device, this utility model can improve the cooling efficiency of the vacuum sintering furnace, thereby refining the material grains, improving mechanical properties, and reducing the scrap rate. Attached Figure Description

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0015] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0016] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a rapid cooling device for a large horizontal vacuum sintering furnace, including a vacuum sintering furnace 1, a placement chamber 2, and a cooling device 3. The placement chamber 2 is located on the left and right sides of the top of the vacuum sintering furnace 1. The cooling device 3 is fixedly connected to the inside of the placement chamber 2. The cooling device 3 includes an insulation layer 301, a lifting rod 302, an electric drive platform 303, a vacuum sealing device 304, and a mounting flange 305. The lifting rod 302 is fixedly connected to the top of the insulation layer 301. The vacuum sealing device 304 is slidably connected to the surface of the lifting rod 302. The mounting flange 305 is fixedly connected to the outer surface of the vacuum sealing device 304. The electric drive platform 303 is fixedly connected to the top of the mounting flange 305. Multiple fixing bolts 4 are threadedly connected to the top of the mounting flange 305 at equal intervals. The multiple fixing bolts 4 are threadedly connected to the bottom of the placement chamber 2.

[0017] Specifically, the cooling efficiency of the vacuum sintering furnace 1 can be improved by the cooling device 3, thereby refining the material grains, improving mechanical properties, and reducing the scrap rate.

[0018] Furthermore, during the sintering process, the electric drive platform 303 descends along the lifting rod 302. At this time, the insulation layer 301 overlaps with the insulation layer 301 of the heating zone, achieving a good insulation effect. When cooling is required after sintering, the electric drive platform 303 rises along the lifting rod 302, and the insulation layer 301 separates from the insulation layer 301 of the heating zone. At this time, the heat inside the heating zone can radiate directly outward from the point of separation, greatly reducing the cooling time.

[0019] Working principle: During sintering, the electric drive table 303 descends along the lifting rod 302. At this time, the insulation layer 301 overlaps with the insulation layer 301 of the heating zone, achieving a good insulation effect. When cooling is required after sintering, the electric drive table 303 rises along the lifting rod 302, and the insulation layer 301 separates from the insulation layer 301 of the heating zone. At this time, the heat inside the heating zone can radiate directly outward from the point of separation, greatly reducing the cooling time.

[0020] In summary, by using a combination of a vacuum sintering furnace 1, a placement chamber 2, a cooling device 3, an insulation layer 301, a lifting rod 302, an electric drive platform 303, a vacuum sealing device 304, a mounting flange 305, and fixing bolts 4, the problems of ordinary vacuum sintering furnaces lacking dynamic heat preservation and adjustment structures, failing to quickly release heat after sintering, and having fixed insulation layers that cannot be dynamically adjusted according to the needs of sintering and cooling stages are solved. During sintering, insufficient insulation may cause temperature fluctuations, and during cooling, failure to remove the insulation layer in time may affect the heat dissipation rate.
