Description

Technical Field

[0001] This invention relates to the field of metal welding technology, specifically a welding equipment for the production of metal substrates. Background Technology

[0002] Metal substrates are metals or alloys that serve as the base or underlying material. They typically form the "canvas" or "foundation" for subsequent processing (such as spraying, electroplating, welding, and coating). Different metals are used as substrates depending on the application, such as steel, aluminum, and aluminum alloys. Steel is the most common structural material, used in buildings, bridges, automobile frames, and machinery. It is low in cost and high in strength, but prone to rust and usually requires a protective coating. Metal sheets require welding during production and processing, mainly because welding provides a permanent, high-strength, and well-sealed connection. Welding combines two metal workpieces at the atomic or molecular level by heating, pressurizing, or both, to form a whole. Welding is almost unrestricted by the shape and size of the workpiece and can be used for different thicknesses.

[0003] The prior art discloses Chinese Patent Application No. CN202411463416.7, which discloses an adjustable welding distance metal plate welding device and welding method. It discloses that by designing a fixing mechanism and a welding mechanism, metal plates of different thicknesses and materials can be positioned and fixed for welding. After welding a batch of metal plates of different specifications, only a stop and adjustment are needed to weld the next batch of metal plates of different specifications. This method is not only simple to operate but also highly functional. Through the design of the material-picking mechanism, multiple sets of metal plates can be magnetically attracted at once, allowing for simultaneous welding of multiple sets of metal plates. This results in high welding efficiency. Furthermore, the distance between the two magnetically attracted metal plates during material picking is the final weld distance, eliminating the need for subsequent adjustments, reducing processing steps, and improving work efficiency.

[0004] Although the above-mentioned device can weld metal sheets, it still has some drawbacks in use: 1. When two base materials are welded, they are prone to sliding displacement under external force. When welding their weld seams, since most of them are straight continuous welding, it is impossible to ensure that the base materials are pressed while welding along the weld seam to maintain their stability and smoothness. At the same time, the area below the weld seam is usually sealed, and the high temperature at the weld cannot be circulated quickly. 2. The spatter generated during welding poses certain safety hazards to operators. At the same time, the tiny slag particles that are generated float in the air and are difficult to clean and collect. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for the production of metal substrates, so as to solve the problem mentioned in the background art of how to collect and automatically discharge the spatter generated during welding while performing stable welding on the substrate.

[0010] Preferably, the pressing module includes through slots on both sides of the placement box, ear plates connected to the placement box are fixedly installed on the through slots, vertical rods are slidably installed in the ear plates, I-shaped parts are slidably installed in the through slots, a telescopic plate fixed to the bottom of the vertical rod is fixedly installed on one side of the I-shaped part, a spring is also sleeved on the outside of the vertical rod and the spring is located between the telescopic plate and the ear plates to abut against each other, a rectangular plate is fixedly installed on the telescopic end of the telescopic plate, a roller frame for pressing the surface of the substrate is fixedly installed on the bottom of the rectangular plate, a toothed plate frame is slidably installed in the inner cavity of the placement box, an electric push rod fixed to the placement box is provided on one side of the toothed plate frame, a special-shaped plate is fixedly installed on one end of the electric push rod, and a fixed wheel that meshes with the toothed plate frame is provided on the special-shaped plate.

[0011] Preferably, one side of the telescopic plate is provided with a threaded rod that is rotatably connected to the placement box via a motor. A guide frame is rotatably mounted on the threaded rod, and an adapter block that is slidably mounted on the guide frame and fixed to the telescopic end of the telescopic plate.

[0012] Preferably, the collection module includes a recycling bin, with symmetrically arranged fixing plates on both sides of the recycling bin. Slide rods are fixedly installed on the fixing plates on both sides, and sliding parts are slidably installed on the slide rods. Springs are provided on both sides of the sliding parts and sleeved on the slide rods. An opening and closing plate located at the bottom of the recycling bin and sealing it is fixedly installed on one side of the sliding part.

[0013] Preferably, the inner cavity of the recycling bin has grooves on both sides, and magnetic suction plates are slidably installed in the grooves on both sides. A material discharge rod fixed to the inner cavity of the recycling bin is arranged behind the magnetic suction plate. A spring fixed to the magnetic suction plate is arranged in the groove. An air pump fixed to the recycling bin is arranged behind the magnetic suction plate. A dust suction pipe located in the inner cavity of the recycling bin is arranged on one side of the recycling bin.

[0014] Preferably, recycling hoppers are placed on both sides of the base frame, and two sets of symmetrical baffles are provided on the side of the recycling hoppers away from each other. The top of the two baffles in each set are at the same level as the upper surface of the opening and closing plates on both sides.

[0015] Preferably, the drive unit includes a guide plate fixed to the base frame, a slide plate slidably mounted on the guide plate via an electric slider, and a fixing frame for fixing the box is mounted on the slide plate via an electric push plate that can be raised and lowered.

[0016] The beneficial effects of this invention are: 1. The present invention, through the L-shaped arrangement of the clamping plates, can ensure that the two substrates will not shift even when subjected to the resistance of the other substrate during the welding process, effectively guaranteeing the stability of the two substrates during subsequent welding. The flow groove can ensure the smooth flow of high-temperature gas near the weld during welding, thereby promoting the dispersion of high-temperature gas near the weld. The receiving groove can isolate the spatter or slag inside the placement box when the welding gun is turned on to weld the substrate, and collect the welding spatter or slag with the cooperation of the collection module.

[0017] 2. In this invention, the upward movement of the control frame drives the rotating wheel to rotate, thereby causing the shaft to rotate the flipping frame and the cleaning roller. During the rotation, the cleaning roller is resisted by the substrate and pushes the spring back and then moves upward. At this time, as the cleaning roller follows the flipping frame to rotate, it always travels in contact with the weld surface, thereby cleaning the weld. The heating resistance wire inside the cleaning roller can preheat the weld before welding, thereby preventing cold cracks after welding and reducing welding stress. At the same time, the cleaning roller located at the rear of the welding gun can also perform secondary rolling along the weld after welding.

[0018] 3. After the roller frame of the present invention comes into contact with the surface of the substrate, as the placement box continues to move downward, the roller frame moves upward within the ear plate via the vertical rod, enabling the roller frame to adaptively press on the surface of the substrate. The rotation of the threaded rod also allows the two roller frames to move closer or further apart. When the placement box is continuously moved by the drive unit to cover the recycling hopper, the sliding member, which is blocked by the baffle, moves after squeezing the spring on the sliding rod. The sliding member moves synchronously with the opening and closing plate. When the opening and closing plate moves, the recycling box is opened, and the welding slag collected in the recycling box falls into the recycling hopper. No manual operation is required when discharging the welding slag. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 As attached Figure 1-8 As shown, a welding device for producing metal substrates includes a base frame 1. Clamping plates 12 are provided on both sides of the base frame 1 to restrict the metal substrate. A movable frame 11 is provided below the clamping plates 12 and slides with the base frame 1 via an electric slider. A flow channel 10 is provided in the middle of the base frame 1 to fully expose the welding area of ​​the substrate. A placement box 2 is provided directly above the flow channel 10. A drive unit is provided on one side of the placement box 2 to drive the placement box 2 to perform linear welding along the weld seam. A welding torch 21 for welding the substrate is installed in the inner cavity of the placement box 2. A welding groove 20 is provided below the welding torch 21 at the bottom of the placement box 2. Collection modules are provided on both sides of the bottom of the placement box 2. A pressing module for stabilizing the pressing during the welding of the substrate is provided on the outside of the collection modules. Specifically, firstly, the two substrates to be welded are placed on the clamping plates 12 on both sides. The electric slider is activated, causing the moving frames 11 on both sides to move the clamping plates 12 closer together until the two substrates to be welded are in contact. It should be noted that when the two substrates are joined, both sides are kept flush, and the clamping plates 12 are set in an L-shape, which can ensure that the two substrates will not shift even if they are subjected to the resistance of the other substrate when the weld is joined, effectively ensuring the stability of the two substrates during subsequent welding. Correspondingly, the flow channel 10 can ensure that the two substrates to be welded can be stably placed above the base frame 1, while during subsequent welding, the flow channel 10 is sufficient to ensure the smooth flow of high-temperature gas near the weld, thereby promoting the dissipation of high-temperature gas near the weld. It can be explained that: the opening of the drive unit facilitates the linear movement of the placement box 2, thereby enabling the welding gun 21 to open and perform a linear and stable welding operation on the weld seam of the two spliced ​​substrates. The welding groove 20 can isolate welding spatter or slag inside the placement box 2, and with the help of the collection module, welding spatter or slag splashed into the placement box 2 can be collected. The pressing module allows the welding torch 21 to press the surfaces of the two substrates simultaneously while welding the weld seam, preventing the substrates from loosening or warping due to pressure during welding. At the same time, while pressing the substrate surface, the pressing module can smoothly roll on the substrate surface as the drive unit moves, making the welding operation smoother and more stable.

[0023] Please see Figure 5The placement box 2 has two sets of symmetrical vertical slots. A slide 22 is slidably installed in each slot. A spring connects the top of the slide 22 to the vertical slot. A shaft 23 is rotatably mounted on one side of each slide 22, opposite to each other. A wheel 24 is fixedly mounted in the middle of the shaft 23, and a tilting frame 29 is fixedly mounted at the end of the shaft 23. A cleaning roller 290 is rotatably mounted on the tilting frame 29. The springs prevent the slide 22 from initially being at the bottom of the vertical slot. When the placement box 2 moves downwards closer to the substrate, the wheel 24 rotates under drive, and then the shaft 23 drives the tilting frames 29 on both sides to tilt away from each other. During tilting, the substrate resists the springs, causing the cleaning roller 290 to move upwards. At this time, the cleaning roller 290 follows the tilting frame 29. During the flipping process, the cleaning roller 290 always travels in contact with the weld surface to clean the weld. It should be noted that the cleaning roller 290 is equipped with a heating resistance wire inside, which can preheat the weld before welding, thereby preventing cold cracking after welding and reducing welding stress. Furthermore, the cleaning roller 290 is set on both sides of the welding torch 21. The cleaning roller 290 on one side of the welding torch 21 can also perform secondary rolling along the weld after welding, due to the continuous forward movement of the welding torch 21. This flattens or reduces the weld reinforcement, smooths out minor surface defects such as undercut, arc craters, and surface porosity, and makes it transition smoothly with the base material, further reducing residual stress.

[0024] In this embodiment, an air cylinder 25 fixed to the placement box 2 is provided on one side of the cleaning roller 290. A piston rod 26 facing the substrate is slidably installed inside the air cylinder 25. A control frame 27 is fixedly installed at the bottom of the piston rod 26. A drive plate 28 is provided on both sides of the control frame 27, which meshes with the rotating wheels 24 on both sides respectively. A spring is sleeved on the outside of the piston rod 26, which abuts against the control frame 27 and the air cylinder 25. Since the bottom of the control frame 27 is lower than the cleaning roller 290, when the placement box 2 moves downward in the direction of the substrate, the control frame 27 first abuts against the roller 290. The substrate surface comes into contact. As the placement box 2 continues to move downward, the control frame 27 is abutted by the substrate, thereby pushing the piston rod 26 to compress the gas in the air cylinder 25. When the control frame 27 moves upward, it synchronously drives the drive plate 28 to move upward, thereby driving the rotating wheel 24. Finally, the cleaning rollers 290 on both sides rotate away from each other along the weld seam. When the cleaning rollers 290 are flipped, the present invention can achieve this simply by the reaction force of the substrate received by the control frame 27 when it moves downward. Compared with the existing device, no additional drive is required.

[0025] Please see Figure 4 as well as Figure 5A connecting bucket 3 is fixedly installed at each of the four corners of the placement box 2. The connecting bucket 3 is equipped with a blower pipe 30 and an input pipe 31 that communicates with the air cylinder 25. With the connection bucket 3 and the blower pipe 30, when the piston rod 26 moves upward and flips open the cleaning rollers 290 on both sides, the piston rod 26 compresses the gas in the air cylinder 25 into the connecting bucket 3. Finally, the air cylinder 25 in the connecting bucket 3 blows air into the placement box 2 through the blower pipe 30. Since the welding groove 20 covers the weld, the air in the placement box 2 can directly act on the weld, thereby blowing the residual welding slag in the weld into the placement box 2 so that the collection module can collect the welding slag sputtered and thrown into the placement box 2.

[0026] Please see Figure 3 , Figure 4 as well as Figure 8 In this embodiment, the pressing module includes through slots 4 on both sides of the placement box 2. Ear plates 41 connected to the placement box 2 are fixedly installed on the through slots 4. A vertical rod 42 is slidably installed inside the ear plates 41. A I-shaped component is slidably installed inside the through slots 4. A telescopic plate 43, fixed to the bottom of the vertical rod 42, is fixedly installed on one side of the I-shaped component. A spring is also sleeved on the outside of the vertical rod 42, and the spring is located between the telescopic plate 43 and the ear plates 41 to abut against each other. A rectangular plate 44 is fixedly installed at the telescopic end of the telescopic plate 43. A roller frame 45 for pressing the substrate surface is fixedly installed at the bottom of the rectangular plate 44. A toothed plate frame 40 is slidably installed inside the placement box 2. An electric push rod 401 fixed to the placement box 2 is provided on one side of the toothed plate frame 40. A special-shaped plate 402 is fixedly installed at one end of the electric push rod 401. A fixed wheel 403 that meshes with the toothed plate frame 40 is provided on the special-shaped plate 402. The I-shaped part can slide down in the through groove 4 by the spring abutting the telescopic plate 43. The roller frames 45 on both sides are also fixedly installed on the toothed plate frame 402. 5. After contacting the substrate surface, as the placement box 2 continues to move downwards, the roller frame 45 moves upwards within the ear plate 41 via the vertical rod 42, allowing the roller frame 45 to adaptively press against the substrate surface. Since the toothed plate frame 40 connects the I-beams on both sides within the placement box 2, when the placement box 2 moves to a certain position, the electric push rod 401 retracts, causing the profile plate 402 to move closer to the toothed plate frame 40 until the fixed wheels 403 on the profile plate 402 re-engage with the toothed plate frame 40. At this point, the toothed plate frame 40 cannot move, and simultaneously fixes the I-beams on both sides within the through groove 4. Meanwhile, the roller frames 45 on both sides stably press against the substrate surface on both sides. Furthermore, the rollers at the bottom of the roller frame 45 can simultaneously roll on the substrate surface while the drive unit controls the linear movement of the placement box 2, ensuring continuous pressing of the substrate surface. This effectively prevents the substrate from slipping or shifting during welding.

[0027] Please see Figure 3 as well as Figure 8 One side of the telescopic plate 43 is provided with a threaded rod 46 that is rotatably connected to the placement box 2 via a motor. A guide frame 47 is rotatably mounted on the threaded rod 46. An adapter block 48 that is slidably mounted on the guide frame 47 and fixed to the telescopic end of the telescopic plate 43 is fixed to the guide frame 47. When the motor is turned on, it drives the threaded rod 46 to rotate. When the threaded rod 46 rotates, it drives the guide frame 47 to move horizontally on the threaded rod 46. When the guide frame 47 moves, it drives the telescopic end of the telescopic plate 43 to move through the adapter block 48, thereby moving the roller frame 45 below the rectangular plate 44. When the roller frames 45 on both sides move closer or further apart to adjust their positions, they press the center of the substrate surface of different widths to ensure the stability of the substrate on the clamping plate 12. At the same time, the adapter block 48 slides vertically on the guide frame 47. The telescopic plate 43 can also move up and down freely in the through groove 4 following the I-shaped part.

[0028] Example 2 Based on Example 1, please refer to Figure 4 , Figure 6 as well as Figure 7 The collection module includes a recycling bin 5. Symmetrically arranged fixing plates 51 are provided on both sides of the recycling bin 5. Sliding rods 52 are fixedly installed on the fixing plates 51, and sliding members 53 are slidably installed on the sliding rods 52. Springs are provided on both sides of the sliding members 53 and sleeved on the sliding rods 52. An opening / closing plate 54 is fixedly installed on one side of the sliding member 53, located at the bottom of the recycling bin 5 and used to seal it. In this embodiment, when the drive unit moves the placement bin 2 closer to the baffle 102, the baffle 102 blocks the side of the opening / closing plate 54. As the drive unit moves the placement bin 2 continuously to cover the recycling hopper 101, it is blocked... The sliding member 53 of the plate 102 moves after squeezing the spring on the sliding rod 52. When the sliding member 53 moves, it synchronously drives the opening and closing plate 54 to move. When the opening and closing plate 54 moves, it opens the recycling box 5. At this time, the welding slag collected in the recycling box 5 falls into the recycling hopper 101. Compared with the existing device, the present invention does not require manual operation when discharging welding slag. It only needs to move the placement box 2 to the predetermined position through the drive unit, so that the opening and closing plate 54 can automatically open the bottom of the recycling box 5 when sliding, thereby automatically discharging the welding slag collected in the recycling box 5 into the recycling hopper 101 for recycling.

[0029] The inner cavity of the recycling bin 5 has grooves on both sides, and magnetic suction plates 55 are slidably installed in the grooves on both sides. A material discharge rod 56 fixed to the inner cavity of the recycling bin 5 is arranged behind the magnetic suction plate 55. A spring fixed to the magnetic suction plate 55 is arranged in the groove. An air pump fixed to the recycling bin 5 is arranged behind the magnetic suction plate 55. A dust suction pipe 57 located in the inner cavity of the placement box 2 is arranged on one side of the recycling bin 5. When the air pump is turned on, the welding slag can be sucked into the recycling bin 5 through the dust suction pipe 57. The air pump is a blower and suction fan. After the welding slag enters the recycling bin 5 and is attracted to the magnetic suction plate 55, it drives the magnetic suction plate 55 to move towards the material discharge rod 56. The material discharge rod 56 clears the welding slag attracted on the magnetic suction plate 55 and makes it fall onto the opening and closing plate 54 so that the opening and closing plate 54 is blocked by the baffle 102 so that the welding slag falls into the recycling hopper 101.

[0030] The base frame 1 has two recycling hoppers 101 placed on both sides. Two sets of symmetrical baffles 102 are provided on the side of the recycling hoppers 101 that are far apart from each other. The top of the two baffles 102 in each set is at the same level as the upper surface of the opening and closing plates 54 on both sides.

[0031] The drive unit includes a guide plate 13 fixed to the base frame 1. A slide plate 14 is slidably mounted on the guide plate 13 via an electric slider. A fixing frame 15 for fixing the placement box 2 is mounted on the slide plate 14 via an electric push plate. The slide plate 14 is horizontally slid on the guide plate 13 by opening the electric slider, so that the fixing frame 15 can move the placement box 2 synchronously. Furthermore, the opening of the electric push rod 401 can also adjust the distance between the placement box 2 and the weld seam of the substrate.

[0032] During operation, the two substrates to be welded are first placed on the clamping plates 12 on both sides. The electric slider is activated, causing the moving frames 11 on both sides to move the clamping plates 12 closer together until the two substrates to be welded are in contact. When the two substrates are joined, their two sides remain flush. Since the weld seam formed after the two substrates are in contact is above the flow channel 10, the flow channel 10 is sufficient to ensure the smooth flow of high-temperature gas near the weld seam during subsequent welding. When the placement box 2 moves downward toward the substrate, the control frame 27 first contacts the surface of one side of the substrate. As the placement box 2 continues to move downward, the control frame 27 is abutted by the substrate, thereby pushing the piston rod 26 to control the gas in the air cylinder 25. During compression, the control frame 27 moves upward, synchronously driving the drive plate 28 upward, thereby driving the rotating wheel 24. The rotating wheel 24 rotates under the drive, and then drives the two flipping frames 29 on both sides to flip away from each other through the shaft 23. During the flipping, the substrate resists the spring and moves upward. At this time, the cleaning roller 290 follows the flipping frame 29 and always travels in contact with the weld surface, thereby cleaning the weld. The cleaning roller 290 is equipped with a heating resistance wire inside, which can preheat the weld before welding, thereby preventing cold cracks after welding and reducing welding stress. The cleaning roller 290 is located on both sides of the welding gun 21. The cleaning roller 290 on one side of the welding gun 21 can also... After welding, as the welding torch 21 continues to advance, the cleaning roller 290 located at the rear of the welding torch 21 can perform secondary rolling along the welded seam. The setting of the pressing module allows the welding torch 21 to press the surfaces of the two substrates simultaneously while welding the seam, preventing the substrates from loosening or warping due to pressure during welding. The opening of the drive unit facilitates the linear movement of the placement box 2, thereby enabling the welding torch 21 to perform a linear and stable welding operation at the weld seam of the two spliced ​​substrates. When the piston rod 26 compresses in the air cylinder 25, it compresses the gas in the air cylinder 25 into the connecting barrel 3. Finally, the air cylinder 25 in the connecting barrel 3 blows air into the placement box 2 through the air pipe 30. Due to the welding groove 20 pressing the weld seam... The placement box 2 is covered, so the air inside can directly act on the weld, blowing the residual welding slag into the placement box 2. When the drive unit moves the placement box 2 close to the baffle 102, the baffle 102 blocks the side of the opening and closing plate 54. As the drive unit moves the placement box 2 to cover the recycling hopper 101, the sliding member 53, blocked by the baffle 102, moves after squeezing the spring on the sliding rod 52. The sliding member 53 moves synchronously, driving the opening and closing plate 54 to move. When the opening and closing plate 54 moves, the recycling hopper 5 opens, and the welding slag collected in the recycling hopper 5 falls into the recycling hopper 101. By simply moving the placement box 2 to the predetermined position by the drive unit, the opening and closing plate 54 can automatically open the bottom of the recycling hopper 5 when sliding.This automatically discharges the welding slag collected in recycling bin 5 into recycling hopper 101 for further processing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
