Description

Technical Field

[0001] The present invention relates to the technical field of consumable electrode welding, and in particular to a consumable electrode welding device. Background Art

[0002] At present, in the electroslag consumable electrode welding process, the irregular welding gap between the dummy electrode and the consumable electrode is generally repaired by manual labor or a robot in the welding workstation to control the welding gun. Moreover, before welding the dummy electrode and the consumable electrode, the consumable electrode and the dummy electrode need to be hoisted onto a steel rolling platform, and then the postures of the consumable electrode and the dummy electrode are adjusted by a rotator or manual method. In addition, the consumable electrode and the dummy electrode need to be kept concentric, and the dummy electrode and the consumable electrode cross-section are welded to the joint by a robot holding the welding gun or manually, and the consumable electrode is rolled at the same time during the welding process to finally complete the welding.

[0003] Existing manual welding methods are not only inefficient and labor-intensive, but also require a consumable electrode reaching 400°C when hot welding products like high-speed steel, creating a poor welding environment.

DETAILED DESCRIPTION

[0064] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0065] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0066] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0067] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0068] Reference Figures 1 to 12 , which is an embodiment of the present invention, proposes a consumable electrode welding device for welding a consumable electrode 15 and a dummy electrode 16 together, including a welding robot 1, the welding robot 1 is used to weld the connection 14 of the consumable electrode 15 and the dummy electrode 16; a plurality of roller frames 2, which are arranged at intervals and slidably set on the front side of the welding robot 1; a plurality of bearing seats 3, each of which is slidably set on a bearing seat 3; a plurality of rotating wheel frames 4, each of which is provided with at least one rotating wheel frame 4, the consumable electrode The consumable electrode 15 and the dummy electrode 16 are respectively placed on the rotating wheel frame 4, which is used to support the consumable electrode 15 and the dummy electrode 16. The consumable electrode 15 and the dummy electrode 16 are concentrically arranged, and the rotating wheel frame 4 is also used to drive the consumable electrode 15 and the dummy electrode 16 to rotate synchronously; the arc frame 12 is located on the ground at the bottom of the connection 14, and the arc frame 12 has a slide 1201; the sliding seat 1202 is arranged on the slide 1201; the hammer 13 is arranged on the sliding seat 1202, the hammer 13 is located at the connection 14, and the hammer 13 is used to hammer the oxide scale of the connection 14.

[0069] In the above scheme, the welding robot 1 possesses high-precision motion control capabilities, enabling precise positioning at the junction 14 between the consumable electrode 15 and the dummy electrode 16 for welding operations. Four roller frames 2 are provided, slidably connected to the track 9. The rotating wheel frame 4 on the support base 3 utilizes rubber-wrapped metal wheels, which not only provide excellent support for the electrodes but also effectively drive the electrodes to rotate synchronously, accommodating consumable and dummy electrodes 15 of varying diameters. For example, when welding the consumable electrode 15 and the dummy electrode 16, the support base 3 and the rotating wheel frame 4 can be adjusted to quickly achieve concentric alignment.

[0070] Working process: First, the consumable electrode 15 and the dummy electrode 16 are hoisted and placed on the corresponding rotary frame 4, and the concentricity is preliminarily adjusted using the adjustment device on the rotary frame 4. The roller frame 2 operates according to the preset program, sliding in front of the welding robot 1 and adjusting to the appropriate welding position spacing to ensure that the welding gun of the welding robot 1 can accurately cover the welding area. Then the welding robot 1 is started, and the robotic arm 101 drives the welding gun to the starting welding point and begins welding the connection 14 between the consumable electrode 15 and the dummy electrode 16. During the welding process, the rotary frame 4 rotates the consumable electrode 15 and the dummy electrode 16 synchronously at the set speed to ensure that the welding surface is evenly heated and stable welding is achieved.

[0071] Secondly, it should be noted that before welding, according to the welding position of the electrode, the arc frame 12 is installed above the connection 14 so that the hammer 13 is aligned with the welding part. When started, the hammer 13 hammers the connection 14 at a preset frequency, such as 30 times per minute with an impact force of 50N. During the hammering process, the sliding seat 1202 can be fine-tuned on the slide 1201 according to the changes in the welding part to ensure that the hammer 13 hammers in the correct position. After the hammering is completed, the arc frame 12 is removed without affecting the subsequent welding operation. The arc frame 12 and the sliding seat 1202 can adapt to the shape of the electrode welding part, making it convenient for the hammer 13 to act accurately on the oxide scale. The position accuracy of the hammer 13 during operation avoids damage to the electrode due to hammering deviation, while ensuring the oxide scale removal effect, which is conducive to improving the quality of the welded joint.

[0072] The automated welding robot 1 replaces manual welding, significantly improving welding precision and avoiding irregular welds caused by factors such as hand tremors, ensuring stable and reliable welding quality. It also prevents workers from working in harsh welding environments. The combination of the roller frame 2 and the rotating wheel frame 4 enables rapid, concentric arrangement and synchronous rotation of the consumable electrode 15 and the dummy electrode 16. Compared to manual adjustment and rolling of the electrodes, this significantly reduces preparation time and improves overall welding efficiency.

[0073] Furthermore, it also includes a gun cleaning station 5, which is arranged on one side of the welding robot 1. The gun cleaning station 5 has a gun cleaning unit 501, a wire cutting unit 502 and a silicone oil spraying unit 503. The gun cleaning unit 501 is used to clean the welding slag on the nozzle of the welding robot 1, the wire cutting unit 502 is used to correct the welding end of the welding wire, and the silicone oil spraying unit 503 is used to inject silicone oil into the inner surface of the nozzle of the welding robot 1.

[0074] In the above scheme, the gun cleaning unit 501 is equipped with a powerful air spray gun and a rotary reamer. The air spray gun pressure can reach 0.6MPa, which can effectively blow off the welding slag. The rotary reamer speed can reach 1500rpm, which can quickly clean the welding slag in the nozzle. The wire cutting unit 502 uses an electric wire cutter to trim the welding end of the welding wire flat and smooth, ensuring a good arc starting effect at the welding end of the welding wire. The silicone oil spraying unit 503 is equipped with a micro plunger pump that can control the injection amount of silicone oil. The double nozzle cross-injection angle is 60°, so that the silicone oil evenly covers the inner surface of the nozzle. For example, when welding a high-strength alloy steel consumable electrode 15, the gun cleaning station 5 automatically starts every 5 welding cycles to maintain the welding gun of the welding robot 1.

[0075] After completing a certain number of welding tasks, the welding robot 1 automatically moves to the gun cleaning station 5. Gun cleaning unit 501 is activated first, using an air spray gun to clean the weld slag from the nozzle. A rotary reamer then extends and rotates deep into the nozzle to remove any remaining weld slag. Wire cutting unit 502 then operates, using an electric wire cutter to trim the excess wire end and adjust it to the appropriate length. Finally, silicone oil spraying unit 503 is activated, and a micro-plunger pump sprays silicone oil through two nozzles in a cross-directional pattern onto the inner surface of the nozzle, forming an anti-stick coating. By promptly cleaning weld slag from the welding gun nozzle, slag accumulation that affects welding quality, such as defects such as weld porosity and slag inclusions caused by slag, is prevented, ensuring welding stability. Precise wire cutting optimizes arc starting, improves stability during the initial welding phase, and reduces defects at the welding starting point. Silicone oil spraying effectively reduces the adhesion of weld slag to the nozzle, reduces the frequency of welding gun cleaning, extends the service life of the welding gun, and reduces equipment maintenance costs and downtime.

[0076] Furthermore, the welding robot 1 includes a robotic arm 101, which has several degrees of freedom; a water-cooled welding gun 102 is detachably arranged on the robotic arm 101, and a nozzle is arranged on the water-cooled welding gun 102; a weld seam tracking sensor 103 is arranged on the robotic arm 101, and the weld seam tracking sensor 103 is located on a side close to the water-cooled welding gun 102, and the weld seam tracking sensor 103 is used to monitor the welding condition.

[0077] In the above scheme, the robotic arm 101 has 6 degrees of freedom and can flexibly and accurately drive the water-cooled welding gun 102 to the welding position. The water cooling system of the water-cooled welding gun 102 adopts a closed-loop cooling circuit, and the cooling water flow rate can reach 3L / min, ensuring that the welding gun does not overheat during long-term welding. The nozzle is made of ceramic material, which is resistant to high temperatures and wear, and the inner surface is treated with an anti-stick coating. The anti-stick coating treatment is an existing technology in this field and will not be described in detail here. The weld tracking sensor 103 is installed at the front end of the robotic arm 101 near the water-cooled welding gun 102, and can monitor the position, width and other parameters of the weld in real time, with a monitoring accuracy of up to 0.01mm. For example, when welding a large-diameter consumable electrode 15, the sensor can accurately capture subtle changes in the weld and provide an accurate adjustment basis for the welding robot 1.

[0078] Before welding, the robotic arm 101 moves the water-cooled welding gun 102 and the weld seam tracking sensor 103 to the welding starting position. The sensor performs a preliminary scan of the weld seam, capturing initial weld state information such as position and groove shape, and transmits this information to the control system. During welding, the sensor continuously monitors the weld seam. Once it detects any weld seam deviation, such as weld seam offset due to electrode thermal deformation, it immediately transmits this deviation data to the control system of the welding robot 1. Based on this deviation data, the control system drives the robotic arm 101 to adjust the position and posture of the water-cooled welding gun 102, as well as welding parameters such as welding speed and wire feed speed, in real time, ensuring that the gun is always aligned with the weld seam center for high-quality welding. The multi-degree-of-freedom robotic arm 101 provides the welding gun with high flexibility, adapting to various complex weld shapes and meeting the welding requirements of electrodes of different specifications. The efficient water-cooled welding gun 102 ensures the stability of the welding process, avoids fluctuations in weld quality caused by gun overheating, extends the continuous welding time, and improves production efficiency. The high-precision weld tracking sensor 103 realizes real-time monitoring and adaptive adjustment of the welding process, effectively overcomes the influence of factors such as electrode thermal deformation and tooling accuracy on weld quality, and significantly improves welding quality.

[0079] Furthermore, it also includes a robot control cabinet 6, which is arranged on one side of the welding robot 1 and is electrically connected to the robotic arm 101; a water-cooled welding machine control cabinet 7 is arranged on one side of the welding robot 1 and is electrically connected to the water-cooled welding gun 102; an electric control cabinet 8 is arranged on one side of the welding robot 1 and is electrically connected to the robot control cabinet 6, the water-cooled welding machine control cabinet 7 and the weld tracking sensor 103.

[0080] In the above solution, the robot control cabinet 6 is connected to the robotic arm 101 via industrial Ethernet, making it easy for operators to program and debug the welding process according to different needs. The electrical control cabinet 8 is connected to the robot control cabinet 6, the water-cooled welding machine control cabinet 7, and the weld tracking sensor 103 via cables to ensure stable signal transmission.

[0081] The operator pre-sets the welding robot 1's motion trajectory, welding speed, welding current, and other process parameters on the robot control cabinet 6 based on the parameters of the consumable electrode 15 and the dummy electrode 16. During welding, the weld tracking sensor 103 transmits the collected weld information to the electrical control cabinet 8, which analyzes and processes this information. It sends instructions to the robot control cabinet 6 to adjust the movement of the robotic arm 101 and to the water-cooled welding machine control cabinet 7 to adjust parameters such as welding current and voltage in real time. The water-cooled welding machine control cabinet 7 outputs stable current and voltage according to the instructions from the electrical control cabinet 8, providing energy for welding. It also feeds back its operating status information, such as temperature and actual current values, to the electrical control cabinet 8, ensuring the coordinated and stable operation of the entire welding system. The robot control cabinet 6 controls the motion of the welding robot 1, ensuring the precise execution of its complex movements and improving the degree of welding automation and precision.

[0082] Furthermore, it also includes a track 9, which is laid on the front side of the robot arm 101, and a plurality of roller frames 2 are slidably set on the track 9.

[0083] In the above scheme, the track 9 is made of I-steel, and the roller frame 2 can flexibly adjust the spacing on the track 9 according to the working position of the welding robot 1 to adapt to different welding requirements. During installation, the track 9 is fixed on the welding workbench according to the preset horizontal and vertical requirements. Before welding, according to the length of the consumable electrode 15 and the dummy electrode 16, the roller frame 2 is pushed to move on the track 9 through an automated device, and the spacing between the roller frames 2 is adjusted to support the electrodes. During the welding process, as the welding position changes, the roller frame 2 can slowly slide on the track 9 according to the control system instructions, driving the electrode to move, ensuring that the welding robot 1 is always in the optimal welding position.

[0084] Furthermore, the roller frame 2 includes a movable frame 201, which is slidably set on the track 9; an auxiliary cross bar 202 is set on the movable frame 201, and both ends of the auxiliary cross bar 202 slide and abut against the outer wall of the track 9, and the auxiliary cross bar 202 is used to limit the direction of the movable frame 201 perpendicular to the track 9; a drive motor 203 is set on the movable frame 201, and the drive motor 203 is used to drive the movable frame 201 to move along the track 9.

[0085] In the above scheme, the pulley at the bottom of the mobile frame 201 cooperates with the track 9, and the auxiliary cross bar 202 installed on the side, the cross bar and the outer wall of the track 9 are in rolling contact, which can achieve positioning. The drive motor 203 drives the mobile frame 201 to move on the track 9. When started, the control system sends a movement instruction to the drive motor 203, and the drive motor 203 causes the mobile frame 201 to start moving along the track 9. During the movement, the two ends of the auxiliary cross bar 202 ensure the stability of the mobile frame 201 perpendicular to the direction of the track 9 to prevent it from deflecting. When the mobile frame 201 reaches the predetermined position, the drive motor 203 stops rotating, and the mobile frame 201 relies on its own positioning device such as the positioning pin and the positioning hole to be fixed on the track 9, waiting for the next operation.

[0086] Furthermore, it also includes a blocking column 10, which has several blocking columns 10 and is respectively arranged at both ends of the track 9; the abutment block 11 is arranged on the end surface of the movable frame 201, and after the movable frame 201 moves to one end of the track 9, the abutment block 11 abuts against the blocking column 10.

[0087] In the above scheme, when the roller frame 2 needs to move toward one end of the track 9, the drive motor 203 drives it forward. As the mobile frame 201 approaches the end of the track 9, the operator or the control system monitors its position through the sensor. When the mobile frame 201 is about to reach the end, the drive motor 203 gradually slows down until the abutment block 11 lightly contacts the stop column 10. At this time, the mobile frame 201 stops moving and completes precise positioning. If the roller frame 2 needs to move in the opposite direction, the drive motor 203 reverses, driving the mobile frame 201 to leave the stop column 10 and move in the other direction. The combination of the stop column 10 and the abutment block 11 provides a reliable end limit for the roller frame 2, preventing the roller frame 2 from sliding off the track 9 and ensuring the safety of the equipment.

[0088] Furthermore, it also includes a flue gas adsorption box 17, which is arranged on the side of the sliding seat 1202 away from the hammer 13, and the bottom of the flue gas adsorption box has a smoke exhaust port 1701, and the smoke exhaust port 1701 is externally connected to a smoke exhaust pipe; the extension tube 18 is arc-shaped, and the extension tube 18 has a plurality of air inlets 1801, and the extension tube 18 is slidably arranged on the flue gas adsorption box 17, and the air inlet 1801 is connected to the flue gas adsorption box 17; the rotating adsorber 19 is rotatably sleeved on the extension tube 18, and the rotating adsorber 19 has a plurality of adsorption heads 1901, and the plurality of adsorption heads 1901 are all connected to the flue gas adsorber 19; there are a plurality of blades 21, and the plurality of blades 21 are arranged at intervals on the inner wall of the rotating adsorber 19.

[0089] In the above scheme, the fume adsorption box 17 is positioned away from the hammer 13. Specifically, a negative pressure blower is located in the middle of the inner side of the fume adsorption box 17. Connected to the negative pressure blower is a fume exhaust port 1701 located at the bottom of the fume adsorption box 17. A deflectable baffle is provided at the fume exhaust port 1701 to control its opening and closing. Furthermore, a soft fume exhaust duct is installed on the fume exhaust port 1701 to discharge the fume to a centralized location for fume treatment. Most importantly, an extension tube 18 is installed on the fume adsorption box 17. The extension tube 18 is in the shape of an upward curve, and the curvature of the extension tube 18 is preferably the same as or similar to that of the consumable electrode 15. This allows the fume, which would otherwise drift upward during welding, to be directly drawn into the extension tube 18. The fume then enters the extension tube through the air inlet 1801 and then into the fume adsorption box 17, preventing the fume from drifting away. It should be noted that the extension tube 18 is also equipped with a rotatable rotating adsorber 19. Specifically, the extension tube 18 is divided into two sections with a gap between them. The rotating adsorber 19 is rotatably mounted in this gap. Blades are welded to the inner wall of the rotating adsorber 19 at intervals. The high-speed flow of flue gas in the adsorption tube 18 drives the blades to rotate, thereby rotating the rotating adsorber 19. This can clean up flue gas that has drifted to different locations and improve the flue gas adsorption effect.

[0090] Furthermore, it also includes a roller 20 rotatably disposed on the flue gas adsorption box 17 , with one side of the roller 20 abutting against the outer wall of the extension tube 18 , and the other end of the roller 20 abutting against the consumable electrode 15 .

[0091] Reference Figure 12 The extension tube 18 is provided with a square hole at a position inside the fume adsorption box 17, and the extension tube 18 is directly connected to the fume adsorption box 17 through the square hole. In addition, a roller 20 is provided on the top outer wall of the extension tube 18. The roller 20 can choose whether to abut against the consumable electrode 15. When the consumable electrode 15 rotates clockwise for welding, the roller 20 will rotate counterclockwise. At this time, the extension tube 18 will also rotate slowly to fully absorb the fume during welding. It should be noted that the square hole must always be in the fume adsorption box 17, so every time the extension tube 18 rotates to a certain position, the extension tube 18 needs to be reset. The position-adjustable adsorption method can greatly improve the fume adsorption effect and also facilitate accurate welding.

[0092] Furthermore, the hammer 13 includes a mounting base 131, which is arranged on the sliding base 1202; a support 132 is arranged on an inclined rod 136 on the mounting frame, which is arranged on the outer wall of the support 132, one end of the hammer rod 133 is hinged to the support 132, and the other end is equipped with a hammer head 134, and the middle part of the hammer rod 133 has a connecting end 1331 and an abutting end 1332; a rotating block 137 is arranged in the support 132, and the rotating block 137 abuts on the abutting end 1332. After the rotating block 137 rotates, the rotating block 137 drives the hammer rod 133 to swing back and forth; one end of the compression spring 135 is arranged on the inclined rod 136, and the other end is arranged on the connecting end 1331. The compression spring 135 is used to provide a force for the abutting end 1332 to press against the rotating block 137.

[0093] In the above scheme, before startup, the operating parameters of driver 138, such as the number of rotation steps and speed, are set in the control system based on the thickness and hardness of the oxide scale. During startup, driver 138 receives instructions and drives rotating block 137 to rotate. Rotating block 137 pushes abutting end 1332 of hammer rod 133, causing hammer rod 133 to swing about the hinge point on support 132, and hammer head 134 hammers the oxide scale at connection 14. During the hammering process, compression spring 135 continuously applies force to abutting end 1332 to press rotating block 137, ensuring close contact between hammer rod 133 and rotating block 137 and ensuring the continuity and stability of the hammering action. This allows for targeted treatment based on different oxide scale conditions, improving the efficiency and quality of oxide scale removal.

[0094] Furthermore, it also includes a driver 138 , which is arranged on the mounting seat 131 , and the rotating block 137 is arranged on the power output end of the driver 138 .

[0095] In this solution, the operator selects the appropriate control mode on the driver 138 control panel based on the welding process requirements and the actual electrode scale. For example, speed control mode is used for the initial hammering to quickly and extensively remove scale, while position control mode is used later to precisely remove residual scale. After setting the control mode, the corresponding parameters are entered into the control system. Driver 138 receives the instructions, drives the servo motor to operate according to the set parameters, driving the rotating block 137 to achieve the precise hammering action of the hammer rod 133.
