[0030] See also Figures 1 to 3 As shown, the utility model discloses a working chamber structure for a welding furnace, comprising: a chamber body 1 installed in the welding furnace, a working chamber 11 is provided in the chamber body 1, and a cooling mechanism 2 is provided on at least one outer side surface of the chamber body 1, and the cooling mechanism 2 is used to cool the chamber body 1.

[0031] Specifically, when the product is placed in the working chamber 11 for high-temperature welding, the working chamber 11 is in a sealed state, and the heat in the working chamber 11 is conducted to the chamber body 1 through the gas. The cooling mechanism 2 is used to cool the chamber body 1 to prevent the chamber body 1 from conducting heat to the working parts outside the chamber body 1, thereby preventing the working parts from being damaged due to high temperature, thereby extending the service life of the working parts and the welding furnace.

[0032] In this embodiment, a cooling mechanism 2 is provided on one side of the cavity body 1. In other embodiments, cooling mechanisms 2 may be provided on multiple sides of the cavity body 1 as required to be suitable for different application scenarios.

[0033] In a specific embodiment, the cooling mechanism 2 is a cold water pipe, and a water inlet 21 and a water outlet 22 are respectively provided at both ends of the cold water pipe.

[0034] Specifically, the cold water pipe is composed of the first section, the second section, the third section, the fourth section, the fifth section, the sixth section and the seventh section connected and conducted in sequence, the first section, the second section, the third section, the fourth section, the fifth section, the sixth section and the seventh section are arranged at right angles in sequence, and the first section, the second section, the third section, the fourth section, the fifth section, the sixth section and the seventh section are connected as a whole in a "convex" shape. The cooling water flows into the first section from the water inlet 21 and then flows through the second section, the third section, the fourth section, the fifth section, the sixth section and the seventh section in sequence, and finally discharged from the water outlet 22. Through the above structure, the length of the cold water pipe and the contact area between the cold water pipe and the cavity body 1 are increased, so that the cavity body 1 is fully cooled by the cooling water in the cold water pipe, thereby improving the cooling efficiency.

[0035] Preferably, the tube body of the cold water pipe is welded to the side wall of the cavity body 1, and part of the side wall of the cavity body 1 replaces part of the tube wall of the cold water pipe, that is, the cooling water directly contacts the side wall of the cavity body 1, which improves the heat exchange efficiency between the cooling water and the cavity body 1, thereby improving the cooling efficiency, and does not affect the structural strength of the cavity body 1. In other embodiments, the cold water pipe can also be directly embedded in the cavity body 1.

[0036] In a specific embodiment, the chamber body 1 is provided with a vacuum gauge 12 , an air inlet valve 13 and an air outlet valve 14 connected to the working chamber 11 . The vacuum gauge 12 , the air inlet valve 13 and the air outlet valve 14 are all arranged close to the cold water pipe.

[0037] Specifically, after placing the product in the working chamber 11 and resealing the working chamber 11, the vacuum gauge 12 is first used to evacuate the working chamber 11 to reduce the oxygen content in the working chamber 11, and the bubbles on the surface of the product are broken due to the pressure difference between the inside and outside of the bubbles, and then the air inlet valve 13 is opened and the reducing gas is introduced to prevent the product from undergoing oxidation reaction during the welding process; after the product welding is completed, the air inlet valve 13 and the air outlet valve 14 are opened at the same time, and nitrogen is introduced into the working chamber 11 through the air inlet valve 13, so that the reducing gas is discharged through the air outlet valve 14; the cold water pipe also plays the role of cooling the vacuum gauge 12, the air inlet valve 13 and the air outlet valve 14, so as to prevent the vacuum gauge 12, the air inlet valve 13 and the air outlet valve 14 from being damaged due to high temperature. Through this embodiment, bubbles on the product and oxidation reactions of the product are effectively prevented during the welding process, thereby improving the product yield.

[0038] In a specific embodiment, a temperature probe 15 is further disposed on the chamber body 1 , and the temperature probe 15 extends into the working chamber 11 .

[0039] Specifically, the temperature in the working chamber 11 is detected by the temperature probe 15 , so as to control the temperature in the working chamber 11 .

[0040] In a specific embodiment, the temperature probe 15 is fixedly connected with an aviation plug 151 , which is installed on the cavity body 1 and is disposed close to the cold water pipe.

[0041] Specifically, by providing the aviation plug 151 , it is convenient to install the temperature probe 15 on the cavity body 1 , and the sealing performance is good.

[0042] In a specific embodiment, a cover plate 3 is disposed above the cavity body 1 , an observation window 31 is formed on the cover plate 3 , and an observation glass 32 is embedded in the observation window 31 .

[0043] Specifically, the surface state of the product can be observed through the observation glass 32 to determine the welding condition of the product. Preferably, a seal 33 is provided between the observation window 31 and the observation glass 32 to seal the gap between the observation window 31 and the observation glass 32 and improve the sealing of the working cavity structure; a mounting seat 34 is also provided on the cover plate 3, and the mounting seat 34 is connected to the observation glass 32 to facilitate the installation of the observation glass 32 and effectively prevent the observation glass 32 from falling off from the observation window 31.

[0044] In a specific embodiment, a sealing ring 35 is provided between the cover plate 3 and the cavity body 1 .

[0045] Specifically, the cover plate 3 and the cavity body 1 are detachably connected to facilitate assembly of the working cavity structure. The sealing ring 35 is used to seal the gap between the cover plate 3 and the cavity body 1 to improve the sealing performance of the working cavity structure.

[0046] Preferably, the cover plate 3 is provided with a first connection portion 36, the cavity body 1 is extended outward with a second connection portion 16, and the first connection portion 36 and the second connection portion 16 are detachably connected via a connection piece 37. The first connection portion 36, the second connection portion 16 and the connection piece 37 facilitate the assembly between the cover plate 3 and the cavity body 1 without affecting the structural strength of the cavity body 1.

[0047] In a specific embodiment, a heat insulation plate 38 is further provided between the cover plate 3 and the cavity body 1 .

[0048] Specifically, the heat insulation plate 38 effectively prevents the high temperature in the working chamber 11 from being transmitted to the cover plate 3, and further prevents the high temperature from being transmitted to the outside of the chamber body 1 through the cover plate 3, thereby avoiding high-temperature damage to the working parts outside the chamber body 1 and extending the service life of the working parts and the welding furnace.

[0049] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways.
