Description

Technical Field

[0001] The invention relates to the technical field of radiator welding, in particular to a welding processing device for a plate-type radiator. Background Art

[0002] With the rapid development of modern electronic technology, power equipment, industrial automation and other fields, the performance requirements for heat dissipation devices are becoming increasingly stringent. Plate radiators have been widely used in many industries due to their compact structure, large heat dissipation area, and high heat exchange efficiency. In the manufacturing process of plate radiators, welding is an extremely critical connection process.

On one side of the movable plate, the rotating part is located outside the moving part, and the connection between the heat sink and the oil collecting pipe is welded by a welding assembly. A plurality of heat sinks can be positioned at the same time by arranging the assembly, and the spacing between each heat sink can be made the same. At the same time, the spacing between each heat sink can be adjusted according to the length of heat sinks of different specifications. When the heat sinks of different specifications are too long, the spacing between the heat sinks can be increased. When the spacing between the heat sinks of different specifications are short, the spacing between the heat sinks can be reduced. This can increase the welding efficiency of the heat sink and the oil collecting pipe and avoid affecting the overall performance and stability of the radiator.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-8 The present invention provides a technical solution: a welding processing device for a fin type heat sink, comprising a mounting base 1, an adjusting part 2 in this case is mounted on the mounting base 1, and is height-adjusted and adapted according to the size of the heat sink, a protective part 3 in this case is mounted on the adjusting part 2, and is used to insert into the tooth gap of the heat sink for limiting and preventing deformation, and to further conduct the heat of the heat sink welding, a cooling part 4 in this case is mounted on the mounting base 1, and is used to evenly cover the tooth gap of the heat sink with coolant for cooling, a positioning part 5 in this case is mounted on the mounting base 1 and the adjusting part 2, and is adapted and adjusted according to the tooth gap size of the heat sink, and a feeding part 8 in this case is mounted on the front side of the mounting base 1, and is adapted and clamped and positioned according to the size of the heat sink.

[0024] In the present invention, in order to adapt to heat sinks of different sizes for adjusting the processing height, the adjustment part 2 of this case includes two hydraulic rods 21, and the two hydraulic rods 21 are installed on both sides of the top of the mounting base 1. The inner rod ends of the two hydraulic rods 21 are installed with support arms 22, and the ends of the two support arms 22 are fixedly connected with mounting arms 23. The two mounting arms 23 are both folding structures. The folding structure is light and occupies a small area, which can avoid accidental contact of parts during height adjustment, thereby improving safety. The front ends of the two mounting arms 23 are fixedly connected with limiting plates 24, and a main shaft 25 is fixedly connected between the two limiting plates 24. The limiting plates 24 prevent the movable parts on the main shaft 25 from hitting the mounting arms 23 and causing wear problems, thereby improving safety. A support rod 1 26 is fixedly connected between the bent ends of the two mounting arms 23, and a support rod 27 is fixedly connected between the rear ends of the two mounting arms 23.

[0025] In this embodiment, in order to further enhance the heat dissipation efficiency of the plate radiator welding and prevent the plate teeth from bending and deforming due to welding heat, the protective part 3 of this case includes a sleeve plate 31, and the inner wall of the sleeve plate 31 is fixedly connected to a magnet 32. The sleeve plate 31 is movably sleeved on the outer wall of the main shaft 25 through the magnet 32. The end of the sleeve plate 31 is fixedly connected to a copper cone plate 33. The copper cone plate 33 is inserted between the plate teeth through the cone surface. The different gap distances between the plate teeth can be adapted by adjusting the processing height, so that each plate tooth is subject to a limiting resistance force to avoid the problem of deformation caused by high heat. At the same time, the copper cone plate 33 contacts the plate teeth to further guide the welding heat for discharge, thereby improving the heat dissipation efficiency. A liquid inlet 34 is installed on one side of the top of the copper cone plate 33. The liquid inlet 34 is used for the coolant to enter , liquid outlets 35 are provided on the inclined surfaces on both sides of the copper cone plate 33, and the coolant overflows from the liquid outlets 35 and covers each sheet tooth and the gap between the sheet teeth, so that the coolant coverage is more thorough. After the copper cone plate 33 absorbs heat, it can directly dissipate the heat quickly through the coolant flowing inside, so that the sheet teeth are cooled faster. Each liquid outlet 35 is connected to each other, and each liquid outlet 35 is connected to the liquid inlet 34. In this case, there are several protective parts 3 and they are equally divided and arranged on the main shaft 25. The number of protective parts 3 can be increased or decreased according to the type of sheet radiator that needs to be processed. Each copper cone plate 33 at one end of the main shaft 25 is vertically arranged and fits on the support rod 27. The support rod 27 is used to limit the copper cone plate 33 that needs to be processed to ensure the verticality of the copper cone plate 33 Straightness and avoid excessive flipping, each copper cone plate 33 at the other end of the main shaft 25 is tilted and fits on the support rod 26, the support rod 26 is used to hold the copper cone plate 33 that is not added to the processing to avoid accidental processing touch, the opposite sexes attract each other between every two adjacent magnets 32, in order to more thoroughly cover the plate radiator and enhance the cooling efficiency, the cooling part 4 of this case includes a cooling box 41, the cooling box 41 is filled with coolant, the cooling box 41 is installed in the middle of the top of the mounting base 1, and a water pump 42 is also installed in the middle of the top of the mounting base 1. The water pump 42 adopts an isw200-200ia pipeline centrifugal pump for self-priming and pressurized coolant to pump the coolant from the cooling box 41, and the inlet of the water pump 42 is connected to a pumping pipe 43, and the pumping The pipe 43 is also connected to the cooling box 41, and the outlet of the water pump 42 is connected to a water supply pipe 44. The water supply pipe 44 extends to the top of the cooling box 41 and is connected to a serpentine pipe 45. A pipe rack 46 is provided on the serpentine pipe 45 and is fixed to the top of the outer wall of the cooling box 41 through the pipe rack 46. The serpentine pipe 45 is sequentially connected to water outlets 47 corresponding to the number of the protective parts 3. Each water outlet 47 and the liquid inlet 34 on each copper cone plate 33 need to be connected and installed using an external water supply hose. Manual valves 48 corresponding to the number of water outlets 47 are installed on the serpentine pipe 45. Each manual valve 48 corresponds to a switch to control an adjacent water outlet 47. The corresponding manual valve 48 is opened according to the number of vertical copper cone plates 33 to transport the coolant.

[0026] It is worth noting that in order to adapt to the tooth spacing of the fin type heat sinks of different sizes, the positioning part 5 of the present invention includes a fan box 51, which is installed on the top side of the mounting base 1. A blower is installed in the fan box 51. The outer wall of the fan box 51 is connected to and installed with a plurality of air outlets 52. A ring-shaped air bag 53 corresponding to the number of the air outlets 52 is movably sleeved on the main shaft 25. Each ring-shaped air bag 53 is connected to an air inlet 54. Each air inlet 54 and each air outlet 52 need to be connected to a corresponding external air supply hose. Each ring-shaped airbag 53 is respectively arranged between every two sets of plates 31, and air is sucked from the air outlet 52 through the corresponding air supply hose into the ring-shaped airbag 53 by a blower, so as to expand the ring-shaped airbag 53, thereby adjusting the distance between every two copper cone plates 33 to adapt to the distance between the teeth. An operating table 6 is installed on the other side of the top of the mounting base 1, and a control panel 7 is arranged on the operating table 6. The control panel 7 is electrically connected to the blower, the water pump 42, and the two hydraulic rods 21 respectively. The control panel 7 can more conveniently operate the work of the electrical equipment in this case.

[0027] It is worth noting that in order to adapt to different sizes of fin heat sinks for safe and stable loading and clamping, the loading part 8 of this case includes a discharge base 81, which is installed on the front of the mounting base 1, and two slide rails 82 are installed on the top of the discharge base 81. A fixed support 83 is installed on one side of the top of the discharge base 81. A movable support 84 is slidably connected to the two slide rails 82. The top edges of the fixed support 83 and the movable support 84 on the side close to each other are all grooved structures, and the movable support 84 is far away from the fixed support 83. A handle 85 is installed on one side, and the handle 85 can be used to adjust the position of the movable support 84 on the slide rail 82. A copper skived-tooth radiator 9 is clamped between the slots of the fixed support 83 and the movable support 84. Each copper cone plate 33 vertical at one end of the main shaft 25 is inserted between the teeth of the copper skived-tooth radiator 9 in sequence. A splash guard 10 is installed on the front side of the top of the mounting base 1. The top of the splash guard 10 is a curved structure. The curved structure can buffer the falling splashed coolant to prevent the coolant from crossing the splash guard 10 and contaminating other equipment.

[0028] The working principle is to pull the handle 85 to cause the movable support 84 to slide along the slide rail 82, preset the two slotted spacings between the movable support 84 and the fixed support 83, insert the copper shovel-tooth radiator 9 of corresponding size along the two slots and limit and fix them, select the corresponding number of copper cone plates 33 according to the number of tooth gaps of the current copper shovel-tooth radiator 9, move all the required copper cone plates 33 to the side where the copper shovel-tooth radiator 9 is located along the main axis 25, and every two copper cone plates 33 will be automatically adsorbed and fixed by the magnet 32, and the redundant copper cone plates 33 will not be involved in the processing, then this batch of copper cone plates 33 can be flipped upwards and placed on the support rod 26, so as to stay away from the copper shovel-tooth radiator 9 to avoid accidental touch during subsequent processing.

[0029] The blower draws air through the air supply hose to inflate all the ring-shaped airbags 53. The ring-shaped airbags 53 that are not used for processing are located on the other side of the main shaft 25. Even if they expand, they will not affect the normal processing area. The ring-shaped airbags 53 expand simultaneously to expand each two sets of plates 31. When the expansion distance is appropriate, the blower is stopped, and the main shaft 25 is driven down by the contraction of the hydraulic rod 21, so that each copper cone plate 33 in the vertical state is inserted into the corresponding gap between the teeth of the current copper skived tooth radiator 9. After being inserted to a suitable depth, the conical surface of the copper cone plate 33 will contact the teeth to complete the limit. In this state, the copper skived tooth radiator 9 can be freely welded by a handheld welding gun or an automated multi-axis robot arm. The heat generated during welding will be directly transferred to the copper cone plate 33 through the teeth of the copper skived tooth radiator 9 to accelerate heat conduction. At the same time, the deformation pressure on the teeth caused by high heat will be blocked by the copper cone plate 33 in real time, thereby avoiding the problem of deformation and dislocation of the teeth.

[0030] On the basis of the above work, the water pump 42 is synchronously turned on to extract the coolant in the cooling box 41, and according to the current number of vertical copper cone plates 33, starting from the first manual valve 48 at the connection end of the serpentine tube 45 and the water supply pipe 44, the corresponding number of subsequent manual valves 48 are opened one by one, so that the coolant enters the liquid inlet 34 from the corresponding water supply hose and flows out from the liquid outlet 35, so as to cool the copper cone plate 33 in real time and evenly cover the tooth gap of the copper shovel-tooth radiator 9, thereby accelerating the cooling efficiency. The copper cone plate 33 that does not participate in the processing will not have water leakage problems because the corresponding manual valve 48 remains closed.

[0031] In the present case, all external air supply hoses can pass between support rod 1 26 and support rod 2 27, and all water supply hoses are bypassed from above support rod 1 26, which effectively distinguishes multiple air supply hoses and water supply hoses to avoid entanglement and obstruction. During the welding process, the waste and coolant flowing out can fall into the discharge base 81 for discharge, which greatly reduces the pollution and cleaning pressure on the working area.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
