Description

Technical Field

[0001] The present application relates to the field of brazing technology, and in particular to a low-temperature brazing and high-temperature service brazing material heat treatment device. Background Art

[0002] Brazing refers to a welding method in which the solder with a melting point lower than the welding part and the welding part are heated to the melting temperature of the solder at the same time, and the gap of the solid workpiece is filled with liquid solder to connect the metals. Brazing has small deformation and smooth and beautiful joints. It is suitable for welding precise and complex components composed of different materials, such as electronic packaging operations. The solder is divided into soft solder (solder with a melting point lower than 450℃), hard solder (solder with a melting point higher than 450℃), and high-temperature solder (solder with a melting point higher than 950℃) according to the melting point.

[0003] During brazing operations, workers are required to coordinate the operation of the brazing material and the spray gun to complete the welding operation. This operation method requires a high degree of coordination between the hands. During welding, the brazing material is prone to shaking and shifting, affecting the brazing quality. Long-term work can also easily lead to fatigue. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a low-temperature brazing and high-temperature service solder heat treatment device, which has the advantages of being able to complete the brazing operation with one hand and automatically loading and welding the solder, avoiding the need for both hands to work together, reducing the workload of workers, preventing the solder from shaking and deviating during welding, and ensuring the quality of the brazing operation. It solves the problem that when performing brazing operations, workers need to coordinate the operation of the solder and the spray gun to complete the welding operation. This operation method requires a relatively high degree of coordination between the two hands. The solder is prone to shaking and deviating during welding, affecting the brazing quality, and is prone to fatigue when working for a long time.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a low-temperature brazing and high-temperature service solder heat treatment device, comprising a main body, a base is fixedly sleeved on the outer circumferential surface of the main body, a solder is arranged inside the main body, two rotating shafts are rotatably inserted inside the main body, a rubber seat is fixedly sleeved on the outer circumferential surface of each of the rotating shafts, and the outer circumferential surface of the solder is in close contact with the rubber seat through a groove provided on the outer circumferential surface of the rubber seat.

[0006] Through the above scheme, since during the brazing operation, the worker needs to cooperate with the brazing material and the spray gun to complete the welding operation, this operation method requires a relatively high degree of coordination of both hands. During welding, the brazing material is prone to shaking and shifting, affecting the brazing quality, and long-term work is also prone to fatigue. By arranging both the gun barrel and the brazing material on the main body, the worker can control the brazing material with one hand to perform the welding operation, and the rubber seat drives the brazing material to move downward during the rotation process, so that the brazing material can be automatically loaded during the welding operation, avoiding the need for cooperation of both hands to operate, reducing the work burden of the worker, preventing the brazing material from shaking and shifting during welding, and ensuring the quality of the brazing operation.

[0007] Furthermore, four equidistantly arranged gun barrels are fixedly plugged into the interior of the base, the outer circumferential surface of each gun barrel is fixedly plugged into the interior of the body, and the bottom end of each gun barrel is fixedly connected to a nozzle, which is inclined inward at a certain angle.

[0008] Through the above scheme, by arranging a plurality of gun barrels and nozzles, the bottom end of the solder can be heated evenly and the heating efficiency of the solder is improved.

[0009] Furthermore, a connecting pipe is fixedly inserted inside the base, and a regulating valve is provided on the outer circumferential surface of the connecting pipe.

[0010] Through the above scheme, the temperature of the flame sprayed by the nozzle can be adjusted by the regulating valve, thereby facilitating the brazing operation.

[0011] Furthermore, a collar is fixedly connected to the inner wall of the body, and the outer circumferential surface of the solder is slidably connected to the inner wall of the collar.

[0012] Through the above solution, the position of the solder is limited by the collar, so that the solder can be centered.

[0013] Furthermore, a gear is fixedly sleeved on the outer circumferential surface of each rotating shaft, and the two gears are meshed with each other.

[0014] Through the above scheme, the rotating shaft is linked in reverse under the action of the gear, thereby driving the two rubber seats to rotate in reverse, thereby realizing the feeding operation of the solder.

[0015] Furthermore, a shell is fixedly connected to the back of the body, a motor is arranged inside the shell, and one end of one of the rotating shafts is drivingly connected to the motor.

[0016] Through the above solution, the motor provides power to one of the rotating shafts, and the motor is protected by the casing.

[0017] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each rotating shaft, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the body.

[0018] Through the above solution, the rotating shaft is restricted to avoid sliding and deflecting of the rotating shaft, thereby increasing the stability of the rotating shaft movement.

[0019] Furthermore, an extension rod is fixedly connected to the upper surface of the solder, and a heat insulation sleeve is fixedly sleeved on the outer circumferential surface of the body.

[0020] Through the above solution, the extension rod can prevent the brazing operation from being unable to be performed when the brazing material is short, and the heat insulation sleeve can play a heat insulation role to protect the workers.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The low-temperature brazing and high-temperature service solder heat treatment device arranges both the gun barrel and the solder on the main body, so that the worker can control the solder with one hand to perform the welding operation, and the solder is driven to move downward by the rubber seat during rotation, so that the solder can be automatically loaded during the welding operation, thereby avoiding the need for both hands to perform the welding operation, reducing the workload of the workers, preventing the solder from shaking and deviating during welding, and ensuring the quality of the brazing operation. The device solves the problem that the existing brazing operation method easily causes the solder to shake and deviate, thus affecting the brazing quality, and is prone to fatigue during long-term operation.

The rotating shaft 8 is linked in reverse under the action of the gear 11, thereby driving the two rubber seats 9 to rotate in reverse, thereby realizing the feeding operation of the solder 6.

One end of one of the rotating shafts 8 is transmission-connected to the motor 10, and the motor 10 provides power to one of the rotating shafts 8, and the motor 10 is protected by the shell 13.

[0036] See also Figure 4The outer circumference of each rotating shaft 8 is fixedly sleeved with a limiting ring 12, and the outer circumference of the limiting ring 12 is rotatably connected to the inside of the body 1 to limit the rotating shaft 8, prevent the rotating shaft 8 from sliding and deviating, and increase the stability of the movement of the rotating shaft 8.

[0038] A low-temperature brazing and high-temperature service solder heat treatment device in the present embodiment, by arranging both the barrel 3 and the solder 6 on the body 1, enables the worker to control the solder 6 with one hand to perform welding operations, and drives the solder 6 to move downward during the rotation of the rubber seat 9, so that the solder 6 can be automatically loaded during the welding operation, thereby avoiding the need for both hands to perform welding operations, reducing the workload of workers, preventing the solder 6 from shaking and deviating during welding, and ensuring the quality of the brazing operation, and solving the problem that the existing brazing operation method easily causes the solder 6 to shake and deviate, affecting the brazing quality, and is prone to fatigue after long-term operation.

When brazing operation is required, the brazing material 6 is placed at the position to be welded, and then the external spray gun device is started to spray flames through the connecting pipe 4, the base 2, the barrel 3 and the nozzle 5. The flames sprayed by the four nozzles 5 will gather at the bottom end of the brazing material 6, melt the bottom end of the brazing material 6, and complete the brazing operation. During this period, the motor 10 can be started to drive one of the rotating shafts 8 to rotate.
