Description

An electromagnetic pulse welding device Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and in particular relates to an electromagnetic pulse welding device. Background Technology

[0002] Electromagnetic pulse welding equipment is an advanced welding device that uses electromagnetic force to join metal materials. It generates a strong electromagnetic field by instantaneously releasing a high-energy current pulse, causing the surface of the metal to be welded to undergo high-speed collision and plastic deformation, thereby achieving solid-state joining of metals under conditions of no or low heat input. This device is particularly suitable for welding thin sheet materials and dissimilar metals, and has the advantages of fast welding speed, small heat-affected zone, high joint strength and small deformation.

[0003] However, in practical use, existing electromagnetic pulse welding devices generally have some problems. When clamping and welding workpieces, they cannot ensure that the clamping structure is locked. During the welding process, the clamping structure is easily displaced by reverse pushing force, which affects the welding quality of the workpiece. Furthermore, when welding continuously, the coil of the welding device generates a lot of heat, and existing electromagnetic pulse welding devices cannot effectively dissipate heat from the coil, which will affect the service life of the coil and is not conducive to efficient and stable welding. Therefore, a new type of electromagnetic pulse welding device is needed to solve the above problems. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an electromagnetic pulse welding device that has the advantages of good workpiece clamping effect and effective heat dissipation of the coil, thereby effectively improving the welding quality of the workpiece and the performance of the coil. It solves the problem that existing electromagnetic pulse welding devices cannot stably clamp the workpiece and cannot effectively dissipate heat from the coil, thus affecting the processing quality of the workpiece and the performance of the coil.

[0005] This utility model is implemented as follows: an electromagnetic pulse welding device includes a base plate, with sliding columns symmetrically fixedly connected above the base plate, a top plate fixedly connected above the sliding columns, a moving plate sleeved on the outer side of the sliding columns, two fixed plates symmetrically fixedly connected above the base plate and below the moving plate, a magnet collector fixedly connected between the two fixed plates at the same horizontal position, a coil mechanism provided inside the magnet collector, a heat dissipation mechanism for heat dissipation provided on one side of the coil mechanism, and a locking mechanism for locking the moving plate.

An air inlet connector and an air outlet connector are fixedly connected to one side of the conductor plate. The air inlet connector is connected to the air outlet, and the air outlet connector is connected to the air inlet. A cooler is fixedly installed in the air inlet located at the front.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a first gear, a threaded sleeve, and a threaded part to achieve stable driving and reverse locking of the moving plate, thereby effectively preventing reverse displacement of the workpiece during welding and affecting the welding quality of the workpiece.

[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Referring to Figures 1 to 5, an electromagnetic pulse welding device provided in this embodiment of the present invention includes a base plate 1, with sliding columns 2 symmetrically fixedly connected above the base plate 1, a top plate 3 fixedly connected above the sliding columns 2, a moving plate 4 sleeved on the outer side of the sliding columns 2, two fixed plates 5 symmetrically fixedly connected above the base plate 1 and below the moving plate 4, a magnet collector 6 fixedly connected between the two fixed plates 5 at the same horizontal position, a coil mechanism provided inside the magnet collector 6, a heat dissipation mechanism for heat dissipation provided on one side of the coil mechanism, a locking mechanism for locking the moving plate 4, the locking mechanism including a mounting cavity 7 opened inside the moving plate 4, and a threaded portion 8 opened on the outer side of the sliding column 2. A first gear 9 and a threaded sleeve 10 are threadedly connected to the outer side of part 8. The threaded sleeve 10 is fixedly connected to the lower part of the first gear 9. The first gear 9 is located in the mounting cavity 7. A first through hole 11 is opened below the mounting cavity 7. The threaded sleeve 10 is rotatably connected to the first through hole 11. A second through hole 12 for the sliding column 2 to pass through is opened above the mounting cavity 7. A drive motor 13 is fixedly connected above the moving plate 4. A second gear 14 is rotatably connected inside the mounting cavity 7. The output end of the drive motor 13 extends into the mounting cavity 7 and is fixedly connected to the second gear 14. A transmission gear 15 is also rotatably connected inside the mounting cavity 7. The transmission gear 15 meshes with both the first gear 9 and the second gear 14.

[0024] In use, the drive motor 13 is started, which drives the second gear 14 to rotate. The rotation of the second gear 14 drives the first gear 9 to rotate through the transmission gear 15. The first gear 9 drives the threaded sleeve 10 to rotate, thereby causing the moving plate 4 to gradually approach the base plate 1 through the threaded part 8. The two magnet collectors 6 are then enclosed to form a welding space that is compatible with the workpiece. Then, by charging the coil mechanism, the workpiece can be welded through the magnet collectors 6 (welding through the magnet collectors 6 is existing technology, so it will not be described in detail here). During this process, the heat dissipation mechanism will continuously ventilate and dissipate heat from the coil mechanism. After the welding is completed, the drive motor 13 is reversed, and the moving plate 4 will be driven to gradually move away from the base plate 1, thereby removing the workpiece and installing a new workpiece.

[0025] This configuration allows for stable driving and reverse locking of the moving plate 4 using the first gear 9, threaded sleeve 10, and threaded part 8. This effectively prevents reverse displacement of the workpiece during welding, thus affecting the welding quality. At the same time, by setting up a heat dissipation mechanism, continuous ventilation and heat dissipation can be provided during the operation of the coil mechanism, thereby effectively improving the service life of the coil and ensuring the efficient operation of the equipment.

[0026] Furthermore, the coil mechanism includes a plurality of insulating frames 16 that are fixedly installed inside the magnet collector 6 in sequence. An energized coil 17 is fixedly installed inside the insulating frame 16. A support plate 18 for supporting the energized coil 17 is fixedly installed inside the energized coil 17. A conductor plate 19 is fixedly installed between two adjacent energized coils 17. An inlet 20 and an outlet 21 are provided on the energized coil 17. The inlet 20 and the outlet 21 are electrically connected through the conductor plate 19.

[0027] In use, each energized coil 17 is wrapped around the outside of the magnet collector 6 and connected end to end through the conductor plate 19. When welding is required, current is passed through the front inlet 20, so that the current flows through all the energized coils 17 and flows out from the rear outlet 21, thereby cooperating with the magnet collector 6 to weld the workpiece.

[0028] This setup allows for the rapid connection of each energized coil 17 using the conductor plate 19, ensuring stable current transmission and effectively enhancing the magnetic field generation effect of the equipment, thus guaranteeing high-quality welding of the workpiece.

[0029] Furthermore, the heat dissipation mechanism includes a ventilation slot 22 formed inside the energized coil 17. The two ends of the ventilation slot 22 and the support plate 18 form an air inlet 23 and an air outlet 24. An air inlet connector 25 and an air outlet connector 26 are fixedly connected to one side of the conductor plate 19. The air inlet connector 25 is connected to the air outlet 24, and the air outlet connector 26 is connected to the air inlet 23. A cooler 27 is fixedly installed in the air inlet 23 at the frontmost position.

[0030] In use, each ventilation slot 22 is connected end to end through the interconnected air inlet connector 25 and air outlet connector 26. When the cooler 27 is turned on, it blows out cold air and blows the cold air into each ventilation slot 22 that is connected end to end through the air inlet 23 at the front, thereby continuously cooling and dissipating heat from the energized coil 17. The cooled air is then discharged from the air outlet 24 at the rear.

[0031] This setup allows for efficient heat dissipation of the energized coil 17 using the ventilation slots 22, effectively preventing the energized coil 17 from overheating and affecting the welding quality and service life of the equipment. Furthermore, by setting up the cooler 27 and the interconnected air inlet connector 25 and air outlet connector 26, the connection of each ventilation slot 22 can be made more convenient, and the number of coolers 27 can be reduced while still ensuring stable heat dissipation of the energized coil 17, thereby reducing equipment production costs.

[0032] The working principle of this utility model:

[0033] In use, the drive motor 13 is started, which drives the second gear 14 to rotate. The rotation of the second gear 14 drives the first gear 9 to rotate through the transmission gear 15. The first gear 9 drives the threaded sleeve 10 to rotate, thereby causing the moving plate 4 to gradually approach the base plate 1 through the threaded part 8. The two magnet collectors 6 are then enclosed to form a welding space that matches the workpiece. Then, by charging the coil mechanism, the workpiece can be welded through the magnet collectors 6. During this process, the heat dissipation mechanism will continuously ventilate and dissipate heat from the coil mechanism. After the welding is completed, the drive motor 13 is reversed, and the moving plate 4 will be driven to gradually move away from the base plate 1, thereby removing the workpiece and installing a new workpiece.
