Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding equipment with a welding cooling function. Background Art

[0002] Welding: Also known as fusion welding or brazing, it is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. In modern industrial production, welding technology is widely used in many fields such as automobile manufacturing, aerospace, shipbuilding, and electronic equipment manufacturing, and is one of the key processes for realizing material connection and constructing complex structures.

[0003] Chinese Patent Publication No. 202310658584.0, "A Local Hot Melt Welding Device for Curtain Wall Aluminum Panels", includes a welding torch, a shielding gas output device, a substrate, a support frame, a positioning mechanism, and a cleaning mechanism. The positioning mechanism includes a circulating water storage tank, two outer pressing components, a positioning component, a lower pressing plate, and a lifting electric push rod. An inlet water pump and an outlet water pump are installed on the circulating water storage tank. The lower pressing plate is provided with a first inner pressing plate and a second inner pressing plate, and a moving space is formed between the first inner pressing plate and the second inner pressing plate. A jet groove is provided inside the first inner pressing plate, an air inlet is provided on the outer wall of the first inner pressing plate, a guiding rod is provided on the top of the first inner pressing plate, and a guiding seat is provided on the top of the support frame.

[0004] Although this device provides effective positioning and support during the welding process, it still lacks a cooling function. Existing welding equipment usually relies on manual spraying of water on the surface of the aluminum material for cooling. However, this method is difficult to achieve uniform cooling, resulting in strong thermal stress generated instantaneously inside the welding area. These thermal stresses are extremely likely to cause deformation of the welded part and even cracking, significantly affecting the product quality. Another cooling method is natural air cooling, but this method not only has a slow cooling speed but also affects the welding efficiency, resulting in an overly prolonged welding process. Therefore, there is an urgent need for a welding equipment that can effectively combine welding and cooling functions, which can not only achieve rapid cooling but also effectively reduce the deformation of the workpiece, ensuring high quality and high efficiency during the welding process. Summary of the Invention

[0005] The purpose of the present invention is to provide a welding equipment with a welding cooling function, and the present invention solves the problem that the cooling attachment of the existing welding device cannot rapidly cool while reducing the deformation of the workpiece.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A welding equipment with a welding cooling function, including a plurality of support legs, and a support plate is installed above the support legs. It further includes: Pre-cooling mechanism, including a moving component. The moving component includes a second bidirectional screw. There are threaded blocks arranged outside the second bidirectional screw. A welding torch and a cooling pipe are installed below the threaded blocks, and the cooling pipe is located behind the welding torch; it is used to pre-cool the weld seam. Cooling mechanism, including a water tank and a lifting component. A first bidirectional screw is rotatably arranged inside the water tank. Second rollers are symmetrically installed on the outer wall of the first bidirectional screw. One side of the first bidirectional screw is connected to the second bidirectional screw through a transmission component, and the first bidirectional screw and the second bidirectional screw rotate synchronously; after the weld seam is pre-cooled by the cooling pipe, the lifting component drives the workpiece to descend and abut against the second rollers, and the side of the workpiece away from the weld seam is immersed in the water tank. At this time, the second rollers drive the workpiece to rotate, so that its surface contacts the water in the water tank in turn. Lifting component, including a pressing plate. Connecting rods are symmetrically abutted on the pressing plate. First rollers are symmetrically and rotatably installed on the lower end faces of the connecting rods, which are used to support the workpiece.

[0007] Preferably, the moving component includes a fixed frame. Symmetric support rods are installed on the outer wall of the fixed frame, and the lower end faces of the support rods are installed on the support plate.

[0008] Preferably, a servo motor is fixedly installed on the outer wall of the fixed frame. The output shaft of the servo motor penetrates the fixed frame and is fixedly connected to the second bidirectional screw.

[0009] Preferably, the transmission component includes a first pulley. The first pulley is fixedly connected to the second bidirectional screw. A belt is sleeved on the outer wall of the first pulley. A second pulley is sleeved on the side of the belt away from the first pulley, and the second pulley is fixedly connected to the first bidirectional screw.

[0010] Preferably, two baffle plates are installed on the lower end face of the pressing plate, and the baffle plates are slidably installed inside the fixed frame.

[0013] Preferably, openings are symmetrically formed on the outer wall of the support plate, and a collection box is installed on the lower end face of the opening.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: First, the present invention is provided with a pre-cooling mechanism. After the welding torch welds the workpiece, the cooling pipe blows out air to pre-cool the weld seam, reducing the thermal stress caused by rapid cooling.

[0015] Second, the present invention is provided with a cooling mechanism. When the workpiece is welded and pre-cooled, the pressing plate no longer supports the connecting rod at this time. The connecting rod slides downward on the fixed block, driving the first roller to descend. At this time, the workpiece on the first roller descends, and the workpiece abuts against the second roller below, and the lower half of the workpiece contacts the water in the water tank for cooling. At the same time, the first bidirectional screw drives the workpiece to rotate in the water tank through the second roller. At this time, the surface of the workpiece contacts the water for cooling in turn, which can evenly cool the workpiece and prevent a certain side of the workpiece from continuously contacting the water, resulting in too fast cooling rate and causing deformation.

[0016] Third, the present invention is provided with a scraper. When the first bidirectional screw rotates, it drives the scraper to reciprocate in the water tank. The scraper will push the welding slag through the opening into the collection box to prevent the welding slag from adhering to the surface of the workpiece, keep the workpiece clean, and facilitate subsequent removal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a welding device with welding and cooling functions, including a plurality of support legs 3, and a support plate 2 is installed above the support legs 3. It further includes: The pre-cooling mechanism includes a moving component. The moving component includes a second bidirectional screw 24. There is a threaded block 16 outside the second bidirectional screw 24. A welding torch 17 and a cooling pipe 18 are installed below the threaded block 16, and the cooling pipe 18 is located behind the welding torch 17. Through holes are formed in the outer wall of the threaded block 16, and the through holes are communicated with the cooling pipe 18; the welding torch 17 is an argon arc welding torch, and the cooling pipe 18 is externally connected to an air pump through the through holes; The cooling mechanism includes a water tank 8 and a lifting component. A first bidirectional screw 13 is rotatably arranged inside the water tank 8. Second rollers 21 are symmetrically installed on the outer wall of the first bidirectional screw 13. One side of the first bidirectional screw 13 is connected to the second bidirectional screw 24 through a transmission component, and the first bidirectional screw 13 and the second bidirectional screw 24 rotate synchronously; when the weld seam is pre-cooled by the cooling pipe 18, the lifting component drives the workpiece 9 to descend and abut against the second roller 21, and the side of the workpiece 9 away from the weld seam is immersed in the water tank 8. At this time, the second roller 21 drives the workpiece 9 to rotate, so that its surface contacts the water in the water tank 8 in turn; The lifting component includes a pressing plate 5. Connecting rods 7 are symmetrically abutted on the pressing plate 5. First rollers 19 are symmetrically and rotatably installed on the lower end faces of the connecting rods 7 for supporting the workpiece 9.

[0020] Further, as Figure 1 shown, the moving component includes a fixed frame 6. Symmetrical support rods 1 are installed on the outer wall of the fixed frame 6. The lower end faces of the support rods 1 are installed on a support plate 2.

[0021] Further, as Figure 5 shown, a servo motor 4 is fixedly installed on the outer wall of the fixed frame 6. The output shaft of the servo motor 4 penetrates the fixed frame 6 and is fixedly connected to the second bidirectional screw 24; when the servo motor 4 rotates, it drives the second bidirectional screw 24 to rotate.

[0022] Further, as Figure 3 shown, the transmission component includes a first pulley 10. The first pulley 10 is fixedly connected to the second bidirectional screw 24. A belt 11 is sleeved on the outer wall of the first pulley 10. A second pulley 12 is sleeved on the side of the belt 11 away from the first pulley 10. The second pulley 12 is fixedly connected to the first bidirectional screw 13; when the first pulley 10 rotates, it drives the second pulley 12 to rotate through the belt 11, and the second pulley 12 drives the first bidirectional screw 13 to rotate.

[0023] Further, as Figure 5 shown, two baffles 20 are installed on the lower end face of the pressing plate 5. The baffles 20 are slidably installed inside the fixed frame 6. When the baffles 20 are respectively abutted and squeezed by the threaded block 16, they will drive the pressing plate 5 to slide above the fixed frame 6.

[0024] Further, as Figure 1As shown, the water tank 8 is fixedly installed on the support plate 2 and is used to hold cooling water.

[0025] Furthermore, as Figure 3 shown, a number of fixing blocks 14 are installed on the outer wall of the fixing frame 6. The fixing blocks 14 are slidably connected to the connecting rod 7. The fixing blocks 14 limit the connecting rod 7 to move it up and down.

[0026] Furthermore, as Figure 6 shown, a scraping plate 22 is threadedly connected to the outer wall of the first bidirectional screw 13. The scraping plate 22 is slidably installed inside the water tank 8. When the first bidirectional screw 13 rotates, it drives the scraping plate 22 to reciprocate inside the water tank 8, causing the welding slag to enter the collection box 15, away from the workpiece 9, preventing adhesion and facilitating subsequent cleaning.

[0027] Furthermore, as Figure 6 shown, openings 23 are symmetrically formed on the outer wall of the support plate 2. The collection box 15 is installed on the lower end surface of the openings 23. The openings 23 enable the welding slag to fall into the collection box 15.

[0028] Working principle: Step 1: After connecting to an external power supply and a controller, first place the workpiece 9 on the first roller 19. The first roller 19 supports the workpiece 9. At this time, control the servo motor 4 to rotate. The servo motor 4 drives the second bidirectional screw 24 to rotate. The second bidirectional screw 24 drives the threaded block 16 to move towards the servo motor 4. The threaded block 16 drives the welding torch 17 and the cooling pipe 18 to move. At this time, the welding torch 17 welds the workpiece 9, and the cooling pipe 18 pre-cools the weld seam.

[0029] Step 2: As the threaded block 16 moves, when the threaded block 16 presses against the baffle 20 on the side close to the servo motor 4, the baffle 20 drives the pressing plate 5 to move. At this time, the pressing plate 5 no longer supports the connecting rod 7. The connecting rod 7 slides down on the fixing block 14. The connecting rod 7 drives the first roller 19 to descend. At this time, the workpiece 9 on the first roller 19 descends, and the workpiece 9 abuts against the lower second roller 21, and the lower half of the workpiece 9 contacts the water in the water tank 8 for cooling. Then the threaded block 16 moves away from the servo motor 4.

[0030] Step 3: When the second bidirectional screw 24 rotates, it drives the first pulley 10 to rotate. The first pulley 10 drives the second pulley 12 to rotate through the belt 11. The second pulley 12 drives the first bidirectional screw 13 to rotate. At this time, the first bidirectional screw 13 drives the workpiece 9 to rotate in the water tank 8 through the second roller 21. At this time, the surface of the workpiece 9 contacts the water for cooling in turn, which can cool the workpiece 9 evenly, prevent one side of the workpiece 9 from continuously contacting the water, resulting in too fast cooling rate and causing deformation.

[0031] Fourth step: When the first double-screw rod 13 rotates, it drives the scraper 22 to reciprocate in the water tank 8. The scraper 22 will push the welding slag through the opening 23 into the inside of the collection box 15, preventing the welding slag from adhering to the surface of the workpiece 9, keeping the workpiece 9 clean, and facilitating subsequent removal.

[0032] Fifth step: As the threaded block 16 moves, when the threaded block 16 abuts against the baffle 20 on the side close to the first pulley 10, the baffle 20 drives the pressing plate 5 to press the connecting rod 7, and the connecting rod 7 rises in the fixed block 14. At this time, the first roller 19 drives the workpiece 9 to rise and move away from the water tank 8, facilitating removal.
