Description

Technical Field

[0001] This utility model relates to the field of brazing technology, specifically to a brazing cooling device. Background Technology

[0002] Brazing is a metal joining process that involves heating the metal to a temperature lower than the melting point of the base metal. The filler metal or brazing filler metal, which has a lower melting point than the base metal, melts and then wets and fills the joint gap of the base metal through capillary action, thereby achieving a weld that diffuses and connects with the base metal. Compared with other welding methods, brazing can join dissimilar parts with less deformation. After brazing, the brazed part can be left to cool completely.

[0003] Currently, after brazing, we usually wait for it to cool naturally. However, natural cooling is inefficient. If we use air cooling to lower the temperature, the airflow will blow directly onto the brazed area, causing uneven shrinkage between the brazed area and the base material, resulting in greater thermal stress and the risk of cracking. This will reduce the quality of the brazing. Utility Model Content

[0004] The purpose of this invention is to provide a brazing cooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a brazing cooling device, comprising a support frame, a hollow bearing plate fixedly connected to the front end of the middle part of the support frame, an oil cooling component provided at the top of the support frame, a collecting component provided at the bottom of the support frame, and an air cooling regulating component provided at the bottom of the hollow bearing plate.

[0006] The oil cooling assembly includes a fixed frame that is fixedly installed on the top of the support frame. An oil storage tank is snapped into the inside of the fixed frame. An oil pipe is fixedly connected to the bottom end of the oil storage tank. A spray pipe is snapped into the bottom end of the oil pipe. A ball valve is installed inside the oil pipe. Gears are installed on the surface of the ball valve.

[0007] The bottom of the fixed frame is fixedly connected to a vertical plate, the top wall of the vertical plate is fixedly connected to an electromagnet, a rack is slidably connected to the bottom surface of the vertical plate, a magnetic block is fixedly connected to the top of the rack, and buffer springs are fixedly connected to the inside of the left and right sides of the rack.

[0008] The support frame is composed of a fixed plate at the bottom and a vertical rod fixedly installed at the top of the fixed plate. The surface of the vertical rod is fixedly connected with reinforcing ribs, which can make the support frame provide more stable support for the oil cooling components, thereby ensuring that the oil storage tank can stably cool the welded parts below.

[0009] The oil pipe is connected to the oil storage tank, and the gear is fixedly connected to the valve stem surface of the ball valve. Rotating the gear can drive the valve stem to rotate, and the valve stem can control the opening and closing of the ball valve after rotation, thereby controlling the flow of cooling oil inside the oil pipe.

[0010] The rack and gear are meshed together, and the near ends of the magnetic block and the electromagnet are opposite magnetic poles. The end of the buffer spring away from the inside of the rack is fixedly connected to the surface of the vertical plate. When the electromagnet is energized, it will attract the magnetic block to move upward. At this time, the magnetic block will drive the rack to move upward and drive the meshing gear to rotate. At this time, the gear will drive the valve stem of the ball valve to rotate, thereby opening the ball valve. At this time, the oil can be sprayed downward through the ball valve to cool the weldment below.

[0011] The collection assembly includes a collection tank fixedly installed on the bottom wall of the support frame. A filter screen is snapped into the inside of the top of the collection tank. The collection tank can collect the cooled oil, while the filter screen can filter impurities in the collected cooling oil to ensure that the cooling oil can be reused.

[0012] The air-cooled regulating component includes an annular plate fixedly installed at the bottom of the fixed frame. The bottom end of the annular plate has a bottom groove. A fixed rod is fixedly connected inside the bottom groove. An annular groove is formed on the surface of the middle part of the bottom groove. A rotating plate is rotatably connected to the surface of the fixed rod. A threaded rod is threadedly connected to the top of the rotating plate. An inner groove is formed inside the rotating plate. An air pipe is inserted into the inner groove.

[0013] The threaded rod is fitted and contacts the inner wall of the annular groove on the side closest to the inside of the rotating plate. The bottom end of the inner groove penetrates the bottom end of the rotating plate. The top end of the air pipe is fixedly connected to the output end of the air pump. Gas can be sprayed out through the air pipe inside the rotating plate to cool the environment below. The rotating plate can be rotated to adjust the orientation of its bottom, avoiding the airflow from blowing directly onto the brazing part and preventing the airflow from blowing away the brazing flux residue, thereby avoiding poor brazing effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves placing the workpiece on top of a hollow support plate. The environment near the brazing area is first cooled via an air pipe, thus initially reducing the temperature of the brazing seam. The orientation of the rotating plate is adjusted to prevent airflow from directly hitting the brazing seam, thus avoiding the dispersal of flux and poor brazing results. Cooling oil is then sprayed onto the workpiece through a nozzle, providing oil cooling and improving cooling efficiency while reducing the risk of oxidation at the brazing seam. A filter screen filters and collects the used cooling oil in a collection tank, improving the utilization efficiency of the cooling oil. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a brazing cooling device, including a support frame 1, a hollow bearing plate 3 fixedly connected to the front end of the middle part of the support frame 1, an oil cooling component 2 provided on the top of the support frame 1, a collection component 4 provided on the bottom of the support frame 1, and an air cooling adjustment component 5 provided on the bottom of the hollow bearing plate 3.

[0024] The oil cooling assembly 2 includes a fixed frame 21 fixedly installed on the top of the support frame 1. An oil storage tank 22 is snapped into the inside of the fixed frame 21. An oil pipe 23 is fixedly connected to the bottom end of the oil storage tank 22. A spray pipe 24 is snapped into the bottom end of the oil pipe 23. A ball valve 25 is installed inside the oil pipe 23. A gear 26 is installed on the surface of the ball valve 25.

[0025] The bottom of the fixed frame 21 is fixedly connected to a vertical plate 271, the top wall of the vertical plate 271 is fixedly connected to an electromagnet 272, the bottom surface of the vertical plate 271 is slidably connected to a rack 273, the top of the rack 273 is fixedly connected to a magnet 274, and the inside of the left and right sides of the rack 273 is fixedly connected to a buffer spring 275.

[0026] The support frame 1 is composed of a fixed plate at the bottom and a vertical rod fixedly installed at the top of the fixed plate. The surface of the vertical rod is fixedly connected with reinforcing ribs, which enables the support frame 1 to provide more stable support for the oil cooling component 2, thereby ensuring that the oil storage tank 22 can stably cool the welded parts below.

[0027] The oil pipe 23 is connected to the oil storage tank 22, and the gear 26 is fixedly connected to the valve stem surface of the ball valve 25. Rotating the gear 26 can drive the valve stem to rotate, and the valve stem can control the opening and closing of the ball valve 25 after rotation, thereby controlling the flow of cooling oil inside the oil pipe 23.

[0028] In this configuration, rack 273 and gear 26 are meshed together. The near ends of magnetic block 274 and electromagnet 272 are opposite magnetic poles. The end of buffer spring 275 away from the inside of rack 273 is fixedly connected to the surface of vertical plate 271. When electromagnet 272 is energized, it will attract magnetic block 274 to move upward. At this time, magnetic block 274 drives rack 273 to move upward and drives meshing gear 26 to rotate. At this time, gear 26 drives valve stem of ball valve 25 to rotate, thereby opening ball valve 25. At this time, oil can be sprayed downward through ball valve 25 to cool the weldment below.

[0029] The collection component 4 includes a collection tank 41 fixedly installed on the bottom wall of the support frame 1. A filter screen 42 is snapped into the top of the collection tank 41. The collection tank 41 can collect the oil after oil cooling, while the filter screen 42 can filter impurities in the collected cooling oil to ensure that the cooling oil can be reused.

[0030] The air-cooled regulating component 5 includes an annular plate 51 fixedly installed at the bottom of the fixed frame 21. The bottom end of the annular plate 51 has a bottom groove 52. A fixed rod 53 is fixedly connected inside the bottom groove 52. An annular groove 54 is opened on the surface of the middle part of the bottom groove 52. A rotating plate 55 is rotatably connected to the surface of the fixed rod 53. A threaded rod 56 is threadedly connected to the top of the rotating plate 55. An inner groove 57 is opened inside the rotating plate 55. An air pipe 58 is inserted into the inner groove 57.

[0031] The threaded rod 56 is in contact with the inner wall of the annular groove 54 on the side closest to the inside of the rotating plate 55. The bottom end of the inner groove 57 passes through the bottom end of the rotating plate 55. The top end of the air pipe 58 is fixedly connected to the output end of the air pump. Gas can be sprayed out through the air pipe 58 inside the rotating plate 55 to cool the environment below. The orientation of the bottom of the rotating plate 55 can be adjusted by rotating it to prevent the airflow from blowing directly onto the brazing part and to prevent the airflow from blowing away the flux residue of the brazing, thereby avoiding poor brazing effect.

[0032] Working principle: During use, the operator places the workpiece on the top of the hollow support plate 3 using a clamp. Then, the operator manually rotates the rotating plate 55 so that the bottom of the rotating plate 55 faces the workpiece but is not directly facing it. Then, the threaded rod 56 is rotated so that its bottom abuts against the inner wall of the annular groove 54. At this time, the threaded rod 56 confines the rotating plate 55 to the surface of the fixed rod 53. Then, the air pump connected to the air pipe 58 is driven to blow out compressed gas. The compressed gas is blown through the air pipe 58 to the part near the workpiece, thus cooling the environment near the workpiece and improving the cooling efficiency of the brazing part.

[0033] Then, the electromagnet 272 is energized. At this time, the electromagnet 272 will attract the magnetic block 274 with opposite magnetic poles at its near ends. The magnetic block 274 will drive the rack 273 to move upward. When the rack 273 moves, it will drive the meshing gear 26 to rotate. At this time, the gear 26 will drive the fixed valve stem to rotate. When the valve stem rotates, the ball valve 25 will be opened, that is, the inside of the oil pipe 23 will be opened. Then, the cooling oil inside the oil storage tank 22 will be sprayed downward through the oil pipe 23 and the nozzle 24. The sprayed cooling oil will flow to the cooled weldment, so that the cooling oil will cool the weldment again after the initial cooling, thereby improving the cooling efficiency of the weldment. The cooling oil flowing on the surface of the weldment will continue to flow downward through the surface of the hollow support plate 3. At this time, the cooling oil will be initially filtered through the filter screen 42. Then, the cooling oil will flow into the inside of the collection tank 41 and be collected. Then, the cooling oil with filtered impurities can be poured out from the inside of the collection tank 41 for reuse.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
