Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding equipment with a welding cooling function. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by 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 achieving material connection and constructing complex structures.

[0003] Chinese patent application number 202310658584.0 discloses a “partial hot-melt welding device for aluminum curtain wall panels”, which includes a welding torch, a protective 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 abutment components, a positioning component, a lower pressure plate, and a lifting electric push rod. The circulating water storage tank is equipped with an inlet pump and an outlet pump. The lower pressure plate is provided with a first inner abutment plate and a second inner abutment plate, and a moving space is formed between the first inner abutment plate and the second inner abutment plate. The first inner abutment plate is provided with a jet groove, and an air inlet is provided on the outer wall of the first inner abutment plate. A guide rod is provided on the top of the first inner abutment plate, and a guide seat is provided on the top of the support frame.

[0004] While the device provides effective positioning and support during welding, it lacks cooling capabilities. Existing welding equipment typically relies on manual water spraying onto the aluminum surface for cooling; however, this method struggles to achieve uniform cooling, leading to intense thermal stress within the welding area. This thermal stress easily causes deformation and even cracking of the weldment, significantly impacting product quality. Another cooling method is natural air cooling, but this is not only slow but also affects welding efficiency, causing excessive delays. Therefore, there is an urgent need for welding equipment that effectively combines welding and cooling functions, achieving rapid cooling while effectively reducing workpiece deformation, ensuring high-quality and high-efficiency welding. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device with a welding cooling function. This invention solves the problem that the cooling accessories of existing welding devices cannot cool the workpiece quickly while reducing workpiece deformation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding device with a welding cooling function, comprising a plurality of support legs, and a support plate mounted above the support legs, and further comprising:

[0007] The precooling mechanism includes a moving component, which includes a second bidirectional screw. A threaded block is provided on the outside of the second bidirectional screw. A welding torch and a cooling pipe are installed below the threaded block, and the cooling pipe is located behind the welding torch; it is used to precool the weld.

[0008] The cooling mechanism includes a water tank and a lifting assembly. A first bidirectional screw is rotatably mounted inside the water tank, and second rollers are symmetrically mounted 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 assembly, and the first and second bidirectional screws rotate synchronously. After the weld is pre-cooled by the cooling pipe, the lifting assembly drives the workpiece to descend and abut against the second rollers, and the side of the workpiece away from the weld is submerged in the water tank. At this time, the second roller drives the workpiece to rotate, so that its surface contacts the water in the water tank in sequence.

[0009] The lifting assembly includes an extrusion plate, on which connecting rods are symmetrically abutted. A first roller is symmetrically and rotatably mounted on the lower end of the connecting rods to support the workpiece.

[0010] Preferably, the movable component includes a fixed frame, the outer wall of which is fitted with symmetrical support rods, and the lower end face of the support rods is mounted on a support plate.

[0011] Preferably, a servo motor is fixedly installed on the outer wall of the fixed frame, and the output shaft of the servo motor passes through the fixed frame and is fixedly connected to the second bidirectional screw.

[0012] Preferably, the transmission assembly includes a first pulley, which is fixedly connected to a second bidirectional screw. A belt is fitted on the outer wall of the first pulley, and a second pulley is fitted on the side of the belt away from the first pulley. The second pulley is fixedly connected to the first bidirectional screw.

[0013] Preferably, two baffles are installed on the lower end face of the extrusion plate, and the baffles are slidably installed inside the fixed frame.

[0014] Preferably, the water tank is fixedly mounted on the support plate.

[0015] Preferably, a scraper is threadedly connected to the outer wall of the first bidirectional screw, and the scraper is slidably installed inside the water tank.

[0016] Preferably, the outer wall of the support plate has symmetrical openings, and a collection box is installed on the lower end face of the opening.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] I. The present invention is equipped with a pre-cooling mechanism. After the welding torch welds the workpiece, the cooling pipe blows out air to pre-cool the weld, reducing the thermal stress caused by rapid cooling.

[0019] Second, this invention is equipped with a cooling mechanism. After the workpiece is welded and pre-cooled, the extrusion plate no longer supports the connecting rod. The connecting rod slides downward on the fixed block, and the connecting rod drives the first roller to descend. At this time, the workpiece on the first roller descends and abuts against the second roller below. 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 in sequence for cooling, which can make the workpiece cool evenly and prevent one side of the workpiece from being in continuous contact with water, causing the cooling rate to be too fast and causing deformation.

[0020] Third, the present invention is equipped with a scraper. When the first bidirectional screw rotates, it drives the scraper to move back and forth in the water tank. The scraper pushes the welding slag through the opening into the collection box, preventing the welding slag from sticking to the surface of the workpiece, keeping the workpiece clean, and facilitating subsequent removal.

[0028] Please see Figures 1 to 6 The present invention provides a technical solution: a welding device with a welding cooling function, comprising a plurality of support legs 3, and a support plate 2 mounted above the support legs 3, and further comprising:

[0029] The precooling mechanism includes a moving component, which includes a second bidirectional screw 24. A threaded block 16 is provided on the outside of 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. A through hole is opened on the outer wall of the threaded block 16, and the through hole communicates with the cooling pipe 18. The welding torch 17 is an argon arc welding torch, and the cooling pipe 18 is connected to an external air pump through the through hole.

[0030] The cooling mechanism includes a water tank 8 and a lifting assembly. A first bidirectional screw 13 is rotatably mounted inside the water tank 8. Second rollers 21 are symmetrically mounted 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 assembly, and the first bidirectional screw 13 and the second bidirectional screw 24 rotate synchronously. After the weld is pre-cooled by the cooling pipe 18, the lifting assembly drives the workpiece 9 to descend and abut against the second rollers 21. The side of the workpiece 9 away from the weld is submerged in the water tank 8. At this time, the second rollers 21 drive the workpiece 9 to rotate, so that its surface contacts the water in the water tank 8 in sequence.

[0031] The lifting assembly includes an extrusion plate 5, on which a connecting rod 7 is symmetrically abutted, and a first roller 19 is symmetrically rotatably mounted on the lower end of the connecting rod 7 to support the workpiece 9.

[0032] Furthermore, such as Figure 1 As shown, the moving component includes a fixed frame 6, and symmetrical support rods 1 are installed on the outer wall of the fixed frame 6. The lower end face of the support rods 1 is installed on the support plate 2.

[0033] Furthermore, such as Figure 5 As 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 passes through 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.

[0034] Furthermore, such as Figure 3 As shown, the transmission assembly includes a first pulley 10, which is fixedly connected to a second bidirectional screw 24. A belt 11 is fitted on the outer wall of the first pulley 10, and a second pulley 12 is fitted on the side of the belt 11 away from the first pulley 10. The second pulley 12 is fixedly connected to a 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.

[0035] Furthermore, such as Figure 5 As shown, two baffles 20 are installed on the lower end face of the extrusion plate 5. The baffles 20 are slidably installed inside the fixed frame 6. When the baffles 20 are pressed by the threaded blocks 16, they will drive the extrusion plate 5 to slide above the fixed frame 6.

[0036] Furthermore, such as Figure 1 As shown, the water tank 8 is fixedly installed on the support plate 2; it is used to hold cooling water.

[0037] Furthermore, such as Figure 3 As shown, a plurality of fixing blocks 14 are installed on the outer wall of the fixing frame 6, and the fixing blocks 14 are slidably connected to the connecting rod 7; the fixing blocks 14 limit the connecting rod 7, so that it moves up and down.

[0038] Furthermore, such as Figure 6 As shown, a scraper 22 is threadedly connected to the outer wall of the first bidirectional screw 13. The scraper 22 is slidably installed inside the water tank 8. When the first bidirectional screw 13 rotates, it drives the scraper 22 to move back and forth in the water tank 8, so that the welding slag enters the collection box 15, away from the workpiece 9, to prevent adhesion and facilitate subsequent cleaning.

[0039] Furthermore, such as Figure 6 As shown, the outer wall of the support plate 2 has symmetrical openings 23, and a collection box 15 is installed on the lower end face of the opening 23; the opening 23 allows the welding slag to fall into the collection box 15.

[0040] Working principle: Step 1: After connecting the external power supply and 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 side of the servo motor 4. The threaded block 16 drives the welding gun 17 and the cooling pipe 18 to move. At this time, the welding gun 17 welds the workpiece 9, and the cooling pipe 18 pre-cools the weld.

[0041] 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, and the connecting rod 7 slides down on the fixed 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 second roller 21 below. 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.

[0042] 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 comes into contact with water in sequence for cooling, which can make the workpiece 9 cool evenly and prevent one side of the workpiece 9 from being in continuous contact with water, causing the cooling rate to be too fast and causing deformation.

[0043] Step 4: When the first bidirectional screw 13 rotates, it drives the scraper 22 to move back and forth in the water tank 8. The scraper 22 will push the welding slag through the opening 23 into the collection box 15 to prevent the welding slag from sticking to the surface of the workpiece 9, keep the workpiece 9 clean, and facilitate subsequent removal.

[0044] Step 5: As the threaded block 16 moves, when the threaded block 16 comes into contact with the baffle 20 on the side near 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 away from the water tank 8, making it easy to remove.
