Description

Technical Field

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

[0002] Atmosphere protection aluminum continuous brazing furnace is a soldering processing equipment used for metal brazing and bright heat treatment. It is a kind of brazing equipment. It can prevent aluminum products from oxidizing at high temperatures through inert gas protection such as nitrogen during the brazing process, thereby ensuring the brazing quality. It is mostly used in the manufacture of precious metal materials, so it 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 movable seat, a brazing furnace body and a tray, wherein the middle part of the top of the movable seat is embedded with a brazing furnace body fixedly installed, and the middle part of one side of the brazing furnace body is embedded with a tray movably connected", which can "facilitate the installation and replacement of the elastic cover by the staff, reduce the difficulty of positioning the elastic cover by the staff, and facilitate the staff to store the elastic cover according to the needs, reduce the space volume occupied by the elastic cover when not in use, and ensure the stability of the elastic cover when in use" The effect is good, but when the brazing furnace is in use, it is generally sealed by a single-layer sealing method. The brazing furnace has the characteristics of high temperature and high air pressure, so the problem of high temperature leakage will occur, and the furnace body of the brazing furnace is also high temperature when the brazing furnace is in use. The brazing furnace is generally protected by a protective plate structure, but the protective plate structure is bulky and troublesome to install, which is inconvenient to use 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 residual high temperature of the furnace wall of the brazing furnace will also cause harm to the operator, and the brazing furnace cannot be used safely. Summary of the invention

[0038] It should be noted that the present invention is an atmosphere-protected aluminum continuous brazing furnace. When in use, the support bracket 5 plays a role in placing and fixing. The outer protective shell 1 and the inner protective shell 2 form a two-layer protective structure to wrap and fix the brazing furnace body 4. The brazing furnace body 4 is the main part of the brazing furnace. The metal workpiece is placed in the brazing furnace body 4. The brazing furnace body 4 is used to braze and brightly heat treat the metal. The full set of sealing covers 10 plays a role in sealing the brazing furnace body 4.

[0039] When the brazing furnace body 4 is sealed and closed, the full set of sealing covers 10 rotates around the push-pull connecting rod 8 through the sealing cover rotating shaft 9, so that the full set of sealing covers 10 is parallel to the brazing furnace body 4, and the docking plate 12 is fitted with the docking mounting block 15, and the docking plug 13 is inserted into the docking mounting block 15 for matching connection, and then the top switch cylinder 6 and the bottom switch cylinder 14 are retracted after operation, driving the full set of sealing covers 10 to move backward, so that the full set of sealing covers 10 are sleeved on the outside of the outer protective shell 1 to seal the brazing furnace body 4;
