Description

Technical Field

[0001] The present invention relates to the field of brazing processing, and particularly relates to an atmosphere-protected aluminum continuous brazing furnace. Background Art

[0002] An atmosphere-protected aluminum continuous brazing furnace is a soldering processing device for metal brazing and bright heat treatment, which is a kind of brazing equipment. During the brazing process, it can be protected by inert gases such as nitrogen to prevent the oxidation of aluminum products at high temperatures, thereby ensuring the brazing quality. It is mostly used in the manufacture of precious metal materials and is widely used in the steel industry and metallurgical industry.

[0003] The Chinese patent with the publication number "CN219443765U" discloses "an atmosphere-protected aluminum continuous brazing furnace, including a moving seat, a brazing furnace body, and a tray. The brazing furnace body is fixedly installed in the middle of the top of the moving seat, and the tray is movably connected in the middle of one side of the brazing furnace body". Although it can achieve the effects of "facilitating the installation and replacement of the elastic cover by the staff, reducing the difficulty for the staff to position the elastic cover, also facilitating the staff to unfold and store the elastic cover as needed, reducing the space volume occupied by the elastic cover when not in use, and ensuring the stability of the elastic cover during use", when the brazing furnace is in use, it is generally sealed in a single-layer sealing manner. Since the brazing furnace has the characteristics of high temperature and high pressure inside, there will be a problem of high-temperature leakage. Moreover, the furnace body of the brazing furnace is also at a high temperature during use. Generally, a protective plate structure is used to protect the brazing furnace. However, the protective plate structure is huge, time-consuming to install, and inconvenient for the use of the brazing furnace. At the same time, when the brazing furnace is opened, high temperature and high pressure will spray out of the brazing furnace, causing harm to external operators. The high temperature remaining on the furnace wall of the brazing furnace will also cause harm to the operators, and the brazing furnace cannot be used safely. Summary of the Invention

When the telescopic protective rods 18 are extended, they are arranged outside the outer protective shell 1 and the full set of sealing covers 10. The protective shell collar ring 20 is used to drive the telescopic movement of the telescopic protective rods 18, and then the telescopic protective rods 18 protect the outer protective shell 1.

[0035] In this embodiment, the heat dissipation frame structure 21 includes a heat dissipation rod mounting ring 22, heat dissipation insertion rods 23, connection pipe seats 24, linkage frames 25, and linkage push-pull rods 26. The heat dissipation rod mounting ring 22 is located behind the outer protective shell 1.

Two connection pipe seats 24 are integrally formed on both outer sides of the heat dissipation rod mounting ring 22. Two linkage frames 25 are welded to the upper and lower ends of the heat dissipation rod mounting ring 22. The linkage push-pull rods 26 are fixedly installed at the front ends of the linkage frames 25.

[0036] In this embodiment, both the heat dissipation rod mounting ring 22 and the heat dissipation insertion rods 23 are provided with hollow structures. The connection pipe seats 24 communicate with the interiors of the heat dissipation rod mounting ring 22 and the heat dissipation insertion rods 23. A plurality of heat dissipation insertion rods 23 are arranged in a circular pattern around the center of the heat dissipation rod mounting ring 22. Two water cooling circulation pipes 27 are fixedly installed at the rear ends of the two connection pipe seats 24. The water cooling circulation pipes 27 circulate and input the coolant into the heat dissipation rod mounting ring 22 and the heat dissipation insertion rods 23 through the connection pipe seats 24.

[0037] In this embodiment, the heat dissipation insertion rods 23 are inserted between the inner protective shell 2 and the brazing furnace body 4 and are located in the heat dissipation rod slots 3. The front ends of the upper and lower two linkage push-pull rods 26 are respectively fixedly connected to both sides of the switch connection block 7 and the docking mounting block 15. The linkage push-pull rods 26 are connected to the top switch cylinder 6 and the bottom switch cylinder 14 by connecting the switch connection block 7 and the docking mounting block 15.

[0038] It should be noted that the present invention is an atmosphere-protected aluminum continuous brazing furnace. During use, the support feet 5 play a role of placing and fixing. The brazing furnace body 4 is wrapped and fixed by a two-layer protection structure formed by the outer protective shell 1 and the inner protective shell 2. The brazing furnace body 4 is the main part of the brazing furnace. Metal workpieces are placed into the brazing furnace body 4, and the brazing furnace body 4 is used for brazing and bright heat treatment of the metal. The full set of sealing covers 10 play an effect of sealing the brazing furnace body 4;

[0039] When the brazing furnace body 4 is hermetically closed, the full set of sealing covers 10 rotate around the push-pull connecting rod 8 through the sealing cover rotating shaft 9, making the full set of sealing covers 10 parallel to the brazing furnace body 4. At the same time, the docking plate 12 fits with the docking mounting block 15, and the docking plug post 13 is inserted into the docking mounting block 15 for mating connection. Then, after the top switch cylinder 6 and the bottom switch cylinder 14 operate and retract, they drive the full set of sealing covers 10 to move backward, so that the full set of sealing covers 10 cover the outside of the outer protective shell 1 to seal the brazing furnace body 4;

[0040] When the full set of sealing covers 10 seals the brazing furnace body 4, the protective shell collar 20 simultaneously covers the outside of the outer protective shell 1. Pulling the protective shell collar 20 backward drives the extension of a plurality of telescopic protection rods 18, so that the plurality of telescopic protection rods 18 are arranged on the outside of the outer protective shell 1 and the full set of sealing covers 10, thus forming a protective structure to prevent the outer protective shell 1 and the full set of sealing covers 10 from being directly touched;

[0041] When the brazing furnace body 4 is opened after processing, through the operation of the top switch cylinder 6 and the bottom switch cylinder 14, the full set of sealing covers 10 are driven to move forward, increasing the space in front of the brazing furnace body 4. Therefore, the high-pressure air inside the brazing furnace body 4 is depressurized. At the same time, the exhaust valve 11 outside the full set of sealing covers 10 can be opened to discharge the high-temperature air inside the brazing furnace body 4. Then, the full set of sealing covers 10 are rotated and opened to prevent high pressure and high temperature from hurting people when the brazing furnace body 4 is opened;

[0042] When the top switch cylinder 6 and the bottom switch cylinder 14 push the switch connection block 7 and the docking mounting block 15 to move forward, they also pull the linkage push rod 26 and the linkage frame 25 to move forward, thereby pulling the heat dissipation rod mounting ring 22 and the heat dissipation plug rod 23 to move forward, so that the heat dissipation plug rod 23 is inserted between the inner protective shell 2 and the brazing furnace body 4 and is located in the heat dissipation rod slot 3. The heat dissipation plug rod 23 contacts the brazing furnace body 4 to dissipate heat and cool it. At the same time, the water cooling box 28 circulates and conveys the coolant to the heat dissipation rod mounting ring 22 and the heat dissipation plug rod 23 through the water cooling circulation pipe 27, continuously and quickly cooling the brazing furnace body 4 to prevent the furnace wall temperature from being too high when the brazing furnace body 4 is opened.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
