Brazing furnaces are used in the steel and metallurgical industries. They are primarily used in the automotive industry for filter and refrigeration components, and in the aerospace industry. They can also be used for brazing and bright heat treatment of stainless steel, carbon steel, brass, and copper parts in the refrigerator, air conditioning, electronics, and microwave magnetron industries.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the brazing furnace not only enables the brazing of multiple sets of brazing filler metal at one time, reducing the number of brazing operations, but also facilitates the sealing and locking of the brazing furnace to prevent heat loss, thereby reducing energy consumption during the use of the brazing furnace. In addition, it facilitates the convenient placement and removal of brazing filler metal, and allows for the placement of multiple sets of brazing filler metal at one time.

[0018] (1) Place multiple sets of brazing filler metals on the surfaces of two sets of placement plates, and place the two sets of placement plates on the surfaces of two sets of moving frames respectively. Under the sliding support of the electric trolley on the track, the electric trolley and the electric push rod drive the placement plates and filler metals to move into the brazing furnace body, so as to facilitate the movement of the placement plates to one side of the slide rail. The servo motor drives the placement plates with multiple sets of filler metals to be placed on the surfaces of multiple sets of slide rails. The control panel reverses to open the lifting frame, electric trolley, and electric push rod, so as to facilitate the movement of the moving frame to the outside of the brazing furnace body. The power motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the rotating shaft to rotate, and the rotating shaft drives the door panel to rotate, so as to facilitate the movement of the door panel and the fixing buckle to the surface of the brazing furnace body, so as to facilitate the movement of the brazing furnace body with the cooperation of the two sets of sealing rings. The body and door panel form a sealed space. The first threaded rod is manually rotated to drive the first threaded sleeve to rotate to the side of the fixed buckle, with the hinge axis as the axis. The first threaded sleeve is then manually rotated to move to the surface of the fixed buckle, so that the brazing furnace body and door panel are locked together with the first threaded sleeve and the fixed buckle. This allows the heater to melt the brazing filler metal and fill the weld gap under capillary action, dissolving and diffusing with the base material to form a strong brazed joint. By brazing multiple sets of brazing filler metal at once, energy consumption is saved. The brazing furnace can braze multiple sets of brazing filler metal at one time, reducing the number of brazing operations. It is also convenient to seal and lock the brazing furnace to prevent heat loss, thus reducing energy consumption during the use of the brazing furnace.

[0019] (2) The electric trolley moves the support frame, rotating disk, lifting frame, drive frame, moving frame, placement plate and brazing filler metal to one side of the brazing furnace body. The electric push rod moves the moving frame through the connecting block. Multiple sets of sliding wheels slide on the surface of the drive frame to provide sliding support for the moving frame, so as to facilitate the moving frame to move a placement plate and brazing filler metal to one side of multiple sets of slide rails inside the brazing furnace body. The servo motor drives the second threaded rod to rotate. The second threaded rod drives the second threaded sleeve to move. The second threaded sleeve drives the lifting frame to move. Multiple sets of limit wheels slide on the surface of the lifting frame to provide sliding support for the lifting frame, so as to facilitate the lifting frame to drive the drive frame to move. The drive frame drives the moving frame to move, so as to facilitate the moving frame to place a placement plate and brazing filler metal on the surface of multiple sets of slide rails. The control panel is operated to open the electric trolley in reverse, so as to facilitate the electric trolley to move the moving frame to the brazing furnace body. Externally, a power cylinder drives a rack to move, which in turn drives a gear to rotate. The gear then drives a rotating shaft to rotate, which in turn drives a rotating disk. Multiple limit blocks provide movable support for the rotating disk, facilitating the movement of the rotating disk, lifting frame, drive frame, moving frame, and another set of placement plates to one side of the brazing furnace body. The control panel continues to activate the electric push rod and servo motor, allowing the other set of placement plates and brazing filler metal to be placed on multiple sets of slide rails inside the brazing furnace body. This facilitates the convenient placement of multiple sets of brazing filler metal. Supported by an electric trolley, a brake cylinder moves a brake block to the ground, facilitating the braking of the electric trolley with the support of two sets of brake blocks. This enables convenient placement and removal of brazing filler metal in the brazing furnace, allowing for the placement of multiple sets of brazing filler metal at once, improving the efficiency of brazing in the furnace, and reducing the labor intensity of manual handling.
