Problems solved by technology
[0002] Most of the anti-oxidation solder furnaces in the prior art use stirring to prevent the solder from being oxidized by the air. The purpose is to make the solder evenly heated in the inner tank, thereby preventing a large amount of solder oxidation; Problems, such as the inner tank is heated by the heating rod, the inner tank itself is heated unevenly, stirring can never ensure that all the solder is heated evenly, and the heated solder will always be oxidized by contact with oxygen in the air

Embodiment Construction
[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.
[0021] like figure 1 , 2 , 3 and 4: an air-exhaust type anti-oxidation lead-free soldering furnace, including a furnace body 11, an inner tank 5, a nitrogen nozzle 16 and a square ceramic heating piece 17, and the inner tank 5 is a rectangular parallelepiped and is arranged on the upper part of the furnace body 11. One side of the inner tank 5 is fixed with an L-shaped bracket 9, and seven nitrogen nozzles 16 are arranged on one side of the bracket 9. The nitrogen nozzles 16 are evenly distributed directly above the inner tank 5 and toward the inner tank 5, and the other side is provided with There is a nitrogen gas inlet 8, the nitrogen gas in...

An air-exhaust-type anti-oxidation lead-free soldering furnace comprises a furnace body and an inner container. The inner container is arranged on the furnace body, a support is fixed on the inner container and provided with nitrogen nozzles facing an opening of the inner container, an interlayer is arranged at the bottom of the inner container, and a ceramic heating piece is placed in the interlayer; sliding grooves are correspondingly formed in the two sides of the opening of the inner container, a push plate is arranged between the sliding grooves, the two ends of the push plate are located in the sliding grooves, the middle of the push plate is connected with a multi-level telescopic air cylinder, the free end of a multi-level telescopic rod of the air cylinder is fixed to the middle of the push plate, and a body of the air cylinder is fixed to a furnace body; the ceramic heating piece is adopted to uniformly heat the inner container in the interlayer at the bottom of the inner container, the problem that soldering tin is oxidized due to nonuniform heating is solved, and energy can be used fully; inert gas nitrogen is sprayed to the soldering tin liquid level, the amount, making contact with air, of the soldering tin is reduced, and the soldering tin is more effectively prevented from being oxidized; the designed push plate capable of automatically scraping tin residues is simple in structure, and therefore the air-exhaust-type anti-oxidation lead-free soldering furnace is more convenient and more practical.
Description
technical field [0001] The invention belongs to the technical field of industrial welding, and in particular relates to an air-exhaust type anti-oxidation lead-free soldering furnace. Background technique [0002] Most of the anti-oxidation soldering furnaces in the prior art use stirring methods to prevent the solder from being oxidized by air. The purpose is to allow the solder to be heated evenly in the inner tank, thereby preventing a large amount of oxidation of the solder. This method can cure the symptoms but not the root cause. The problem is that if the inner tank is heated by a heating rod, the inner tank itself is not uniformly heated, and stirring can never ensure that all solders are heated evenly, and the heated solder will always be oxidized by contact with oxygen in the air. SUMMARY OF THE INVENTION [0003] The problem solved by the present invention is to provide an air-exhaust type anti-oxidation lead-free solder furnace that fundamentally prevents the s...
