Description

Technical Field

[0001] The invention relates to the technical field of steel coil welding, and more particularly to a weld processing device with preheating and slow cooling functions. Background Art

[0002] Laser welding equipment is a device that uses a high-energy-density laser beam as a heat source to locally heat the material in a small area, melting the material to form a specific molten pool, and ultimately achieve welding.

[0003] During the construction process in the severely cold areas of northern winter, welding equipment is needed to weld the steel coils. However, before welding the steel coils, the steel coils need to be rolled into a cylindrical shape by the existing rolling pressing device, and then the position of the weld is aligned and fixed by the existing spring clamp, and then the steel coils are hoisted to the welding equipment by the existing lifting equipment, and the steel coils are welded by the welding device. During the process of placing the rolled steel coils on the welding equipment by the lifting equipment, the shaking and swinging of the steel coils will cause the position of the steel coils to be welded to have a position deviation with the welding device, affecting the welding quality of the steel coils by the welding device, and the coiling of the steel coils also increases the steps in the welding process, which not only affects the welding speed of the steel coils by the welding equipment, but also affects the rate of the overall welding process of the steel coils, thereby reducing the welding efficiency of the steel coils by the welding device, and in the low temperature environment of northern winter, after the steel coils are welded, the position of the steel coil welds is affected by the environment, which will cause the welds of the welded steel coils to expand and contract due to heat and contraction and deformation, thereby causing cold cracks at the weld positions of the steel coils, thereby affecting the welding quality of the steel coils by the welding equipment. Summary of the invention

[0004] The object of the present invention is to provide a weld processing device with preheating and slow cooling functions to solve the problems raised in the above background technology: In order to achieve the above object, the present invention provides the following technical solutions: A welding seam processing device with preheating and slow cooling functions comprises a base and a support platform fixedly installed on one end surface, wherein a lift frame is jointly arranged above the base and the support platform, a first inner ring and a second inner ring are correspondingly fixedly installed on the outside of the lift frame, a first outer ring and a second outer ring are respectively fixedly installed on the outside of the first inner ring and the second inner ring, an arc block matching therewith is slidably connected between the first inner ring and the first outer ring, an electric clamp is fixedly installed on the surface of the arc block, an arc plate is jointly fixedly installed between the first outer ring and the second outer ring, a movable top plate is arranged on the surface of the arc plate, a chamfer is arranged on one end surface of the top plate, a steel coil to be welded is arranged between the first outer ring and the second outer ring, a through-type slide groove is opened on the surface of the lift frame, a slider matching therewith is slidably connected to the inside of the slide groove, a retractable laser welding head is fixedly installed on the bottom surface of the slider, and a through-type slot is opened on the inner wall of the second inner ring.

[0005] By adopting the above technical solution, the side end of the flexible steel plate is clamped by the electric gripper, and the rotation of the motor drives the gear to rotate, so that the gear ring rotates and drives the arc block to move, so that the electric gripper follows the arc block to rewind the steel coil. Before the steel coil is formed, the flexible steel plate passes through the arc plate and the top plate to be bent in an arc shape. When the arc block rotates one circle, the end clamped by the electric gripper corresponds to the tail position of the formed steel coil. The knob is manually rotated, and the threaded rod is rotated and extended toward the arc plate under the action of the knob. Since one end of the threaded rod is rotatably connected to the swivel, the top plate is upward at this time. The surface of the steel coil is squeezed by movement so that the distance between the tail of the steel coil and the end weld clamped by the electric gripper adapts to and corresponds to the weld position. Compared with the traditional use of coil pressing equipment to press the steel coil, this device can directly roll and form the steel coil on the welding device at one time, without the need to use a coil pressing device to form the steel coil, and there is no need to place it through a lifting equipment, thus avoiding the situation where the welding position of the steel coil and the position of the welding device are misaligned, reducing the steps of lifting and placing the steel coil in the production process, thereby increasing the welding speed of the laser welding head to the steel coil, and also increasing the welding efficiency of the laser welding head to the steel coil.

[0006] Preferably, the groove corresponds to the welding trajectory of the laser welding head, the arc block is located on one side of the groove, a fixing block is fixedly installed between the first inner ring and the lifting frame, a supporting block is fixedly installed between the second inner ring and the lifting frame, and a fixing rod is fixedly installed between the first outer ring and the bottom surface of the lifting frame.

[0007] Preferably, an annular groove is provided between the first inner ring and the first outer ring, a rotatable gear ring is provided on one side of the first outer ring, a plurality of matching fixing columns are slidably connected inside the annular groove, one end of each of the fixing columns is fixedly connected to the side surface of the gear ring, and the other end of one of the fixing columns is fixedly connected to the arc block.

[0008] Preferably, a connecting plate is fixedly mounted on the surface of the lifting frame, one side of the connecting plate is rotatably connected to a gear meshing with a gear ring, a motor is fixedly mounted on the surface of the connecting plate, and an output end of the motor is fixedly connected to the gear.

[0009] Preferably, a fixing ring is fixedly installed on the bottom surface of the arc plate, a threaded ring is fixedly connected to the bottom surface of the fixing ring, a through-type through groove is opened on the bottom surface of the arc plate, a swivel is fixedly installed on the bottom surface of the top plate, a threaded rod is connected to the internal thread of the threaded ring, one end of the threaded rod is rotatably connected to the swivel, and the other end of the threaded rod is fixedly connected to a knob.

[0010] Preferably, an electric telescopic rod is fixedly mounted on the surface of the support platform, the telescopic end of the electric telescopic rod is fixedly connected to the bottom surface of one end of the lifting frame, a slide is fixedly mounted on the surface of the lifting frame, a sliding seat matching the slide is slidably connected to the surface of the slide, and a drivable intelligent remote control car is fixedly mounted on the surface of the slide.

[0011] Preferably, a mounting plate is fixedly mounted on the surface of the slider, a frame plate is fixedly mounted on the surface of the laser welding head, an electric control push rod is fixedly mounted on the bottom surface of the mounting plate, and an output end of the electric control push rod is fixedly connected to the surface of the frame plate.

[0012] Preferably, an arc-shaped heating device for heating the steel coil to be welded is fixedly mounted on the bottom surface of the frame plate.

[0013] By adopting the above technical solution, when welding the steel coil, the intelligent remote control car travels at a constant speed, carrying the arc heating device and the laser welding head with it. The arc heating device first performs rapid electromagnetic heating on the position of the steel coil weld, and then the laser welding head welds the weld at the heated position. At this time, the arc heating device and the laser welding head move to comprehensively heat and weld the steel coil weld. After welding is completed, the intelligent remote control car is reset. At this time, the laser welding head stops working and follows the intelligent remote control car to reset. The arc heating device continues to work during the resetting process to heat the welded steel coil, preventing the weld of the welded steel coil from being affected by the temperature and causing thermal expansion and contraction, avoiding cold cracks at the weld of the steel coil, and thereby improving the welding quality of the steel coil by the laser welding head.

[0014] Preferably, a plurality of brackets are fixedly installed corresponding to the surface of the base, a rotating plate is rotatably connected between any two of the brackets, a roller is rotatably connected to the bottom surface of any one of the rotating plates, a rotating seat is fixedly installed on the top surface of any one of the rotating plates, a rotating column matching it is rotatably connected inside the rotating seat, a roller is rotatably connected to the surface of the rotating column, a connecting rod is fixedly installed on the surface of any one of the rotating plates, and the plurality of rotating plates are fixedly connected by connecting rods, and the first outer ring and the second outer ring correspond to the positions of the brackets.

[0015] By adopting the above technical solution, the electric telescopic rod contracts and moves the lifting frame downward, and the formed steel coil moves downward. When the surface of the steel coil contacts the roller, as the lifting frame continues to move downward, the turn plate rotates to make the roller contact the surface of the steel coil. The roller fixes the steel coil again before welding to ensure the stability of the steel coil during welding. When the laser welding head completes the welding of the steel coil, it extends from the material trough through an external clamping device, and then clamps the welded steel coil. Subsequently, the electric clamp does not clamp the steel coil. At this time, the clamping device pulls the steel coil outward, and the welded steel coil is taken out from the material trough, which facilitates the unloading of the welded steel coil.

[0016] Preferably, a spring shaft is provided between the rotating plate and the bracket, the rotating plate is rotatably connected to the bracket via the spring shaft, and a material trough for unloading the welded steel coil is provided between the second inner ring and the second outer ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1) When the weld processing device with preheating and slow cooling functions is in use, the electric gripper clamps the side end of the flexible steel plate, and the motor rotates with the gear, so that the gear ring rotates and moves the arc block, so that the electric gripper follows the arc block to rewind the steel coil. Before the steel coil is formed, the flexible steel plate passes through the arc plate and the top plate to bend in an arc. When the arc block rotates one circle, the end clamped by the electric gripper corresponds to the tail position of the formed steel coil. The knob is manually rotated, and the threaded rod rotates and extends toward the arc plate under the action of the knob. Since one end of the threaded rod is connected to the rotating ring, the threaded rod rotates and extends toward the arc plate. At this time, the top plate moves upward to squeeze the surface of the steel coil. When the tail of the steel coil is formed and the distance and position of the weld at the end clamped by the electric clamp correspond, compared with the traditional use of a coil pressing device to press the steel coil, this device can be directly rolled and formed on the welding device at one time. There is no need to use a coil pressing device to form the steel coil, and there is no need to place it through a lifting device, which avoids the situation where the welding position of the steel coil and the position of the welding device are misaligned. The steps of lifting and placing the steel coil are reduced in the production process, thereby increasing the welding speed of the laser welding head to the steel coil, and also increasing the welding efficiency of the laser welding head to the steel coil.

[0018] 2) When the weld processing device with preheating and slow cooling functions is in use, when welding the steel coil, the intelligent remote control car travels at a constant speed, carrying the arc heating device and the laser welding head to move at a constant speed. The arc heating device first performs rapid electromagnetic heating on the position of the steel coil weld, and then the laser welding head welds the weld at the heated position. At this time, the arc heating device and the laser welding head move to comprehensively heat and weld the steel coil weld. After welding is completed, the intelligent remote control car resets, at which time the laser welding head stops working and follows the intelligent remote control car to reset. The arc heating device still works during the resetting process to heat the welded steel coil, preventing the weld of the welded steel coil from being affected by the temperature and causing thermal expansion and contraction, avoiding cold cracks at the weld of the steel coil, and thereby improving the welding quality of the laser welding head on the steel coil.

[0019] 3) When the weld processing device with preheating and slow cooling functions is in use, the electric telescopic rod contracts and moves the lifting frame downward, and the formed steel coil moves downward. When the surface of the steel coil contacts the roller, as the lifting frame continues to move downward, the turn plate rotates so that the roller contacts the surface of the steel coil. The roller fixes the steel coil again before welding to ensure the stability of the steel coil during welding. When the laser welding head completes welding of the steel coil, it extends from the material trough through an external clamping device, and then clamps the welded steel coil. Subsequently, the electric clamp does not clamp the steel coil. At this time, the clamping device pulls the steel coil outward, and the welded steel coil is taken out from the material trough, which is convenient for unloading the welded steel coil.

A motor 26 is fixedly installed on the surface of the connecting plate 24. The motor 26 is a conventional forward and reverse motor in the prior art, and the output end of the motor 26 is fixedly connected to the gear 25.

[0026] A fixing ring 27 is fixedly installed on the bottom surface of the curved plate 10, and a threaded ring 28 is fixedly connected to the bottom surface of the fixing ring 27.

The top plate 11 moves upward to squeeze the surface of the steel coil 13, so that the distance between the tail of the steel coil 13 and the end weld clamped by the electric gripper 9 is adapted to correspond to the weld position.

[0027] An electric telescopic rod 33 is fixedly installed on the surface of the support platform 2, and the electric telescopic rod 33 is a conventional electric telescopic rod 33 in the prior art. The telescopic end of the electric telescopic rod 33 is fixedly connected to the bottom surface of one end of the lifting frame 3, and a slide 34 is fixedly installed on the surface of the lifting frame 3. The surface of the slide 34 is slidably connected with a matching slide seat 35, and the surface of the slide seat 35 is fixedly installed with a drivable intelligent remote-controlled car 36, which is a conventional intelligent remote-controlled car 36 in the prior art.

[0028] A mounting plate 37 is fixedly mounted on the surface of the slider 15, a frame plate 39 is fixedly mounted on the surface of the laser welding head 16, an electric control push rod 38 is fixedly mounted on the bottom surface of the mounting plate 37, and an output end of the electric control push rod 38 is fixedly connected to the surface of the frame plate 39. The electric control push rod 38 is a conventional electric control push rod 38 in the prior art.

[0029] The bottom surface of the frame plate 39 is fixedly installed with an arc heating device 40 for heating the steel coil 13 to be welded. The arc heating device 40 is a conventional electromagnetic heating device in the prior art. The arc heating device 40 is arranged in an arc shape, so that the arc heating device 40 heats the weld position of the steel coil 13 more evenly. When welding the steel coil 13, the intelligent remote control car 36 travels at a constant speed, carrying the arc heating device 40 and the laser welding head 16 at a constant speed. The arc heating device 40 first performs rapid electromagnetic heating on the weld position of the steel coil 13, and then the laser welding head 16 heats the heating part. The arc heating device 40 and the laser welding head 16 move to fully heat and weld the weld of the steel coil 13. After the welding is completed, the intelligent remote control car 36 is reset. At this time, the laser welding head 16 stops working and follows the intelligent remote control car 36 to reset. The arc heating device 40 still works during the resetting process to heat the welded steel coil 13 to prevent the weld of the welded steel coil 13 from being affected by the temperature and causing thermal expansion and contraction, thereby avoiding cold cracks at the weld of the steel coil 13, thereby improving the welding quality of the laser welding head 16 on the steel coil 13.

[0030] The use steps of the present invention are as follows: when the welding seam processing device with preheating and slow cooling functions is used, the flexible steel plate to be welded is first cut, and then the electric telescopic rod 33 is extended to move the lifting frame 3 upward. At this time, the first inner ring 4, the first outer ring 5, the second inner ring 6 and the second outer ring 7 follow the lifting frame 3 to move, and then the side end of the flexible steel plate is clamped by the electric clamp 9. The motor 26 rotates to drive the gear 25 to rotate, so that the gear ring 22 rotates to drive the arc block 8 to move through the ring groove 21 and the fixed column 23 to match, so that the electric clamp 9 follows the arc block 8 to move and rewind the steel coil 13. Before the steel coil 13 is formed, the flexible steel plate is bent into an arc through the arc plate 10 and the top plate 11. When the arc block 8 rotates one circle, the electric The end portion clamped by the clamp 9 corresponds to the tail position of the formed steel coil 13. At this time, the motor 26 is stopped and the knob 32 is manually rotated. At this time, the threaded rod 31 is rotated and extended toward the arc plate 10 under the action of the knob 32. Since one end of the threaded rod 31 is rotatably connected to the swivel 30, the top plate 11 moves upward to squeeze the surface of the steel coil 13, so that the distance between the weld seam of the tail of the formed steel coil 13 and the end portion clamped by the electric clamp 9 is adapted to correspond to the weld seam position. Then, the knob 32 is stopped from rotating. At this time, the weld seam position corresponds to the position of the laser welding head 16. Then, the position of the steel coil 13 to be welded is slightly adjusted so that one end of the steel coil 13 is formed under the action of the electric clamp 9 and the top plate 11, and the other end of the steel coil 13 is inserted between the second inner ring 6 and the second outer ring 7. Then the intelligent remote control car 36 drives the slide seat 35 to slide on the surface of the slide 34. The intelligent remote control car 36 also moves the slider 15 in the slide groove 14, so that the arc heating device 40 and the laser welding head 16 move. When the laser welding head 16 moves to the position where the steel coil 13 is to be welded, the electric control push rod 38 extends and moves downward with the arc heating device 40 and the laser welding head 16. When the arc heating device 40 moves to the height adapted to the welding position of the steel coil 13, the laser welding head 16 is highly adapted to the welding gap. When welding the steel coil 13, the intelligent remote control car 36 travels at a constant speed, and moves at a constant speed with the arc heating device 40 and the laser welding head 16. The arc heating device 40 first welds the weld of the steel coil 13. The position is quickly electromagnetically heated, and then the laser welding head 16 welds the weld of the heated part. Through the setting of the through-type slot 17, the arc heating device 40 and the laser welding head 16 move to comprehensively heat and weld the weld of the steel coil 13. After the welding is completed, the intelligent remote control car 36 is reset. At this time, the laser welding head 16 stops working and follows the reset of the intelligent remote control car 36. The arc heating device 40 still works during the reset process to heat the welded steel coil 13. This solution clamps the side end of the flexible steel plate through the electric clamp 9, and the motor 26 rotates with the gear 25 to rotate, so that the gear ring 22 rotates and moves with the arc block 8, so that the electric clamp 9 follows the arc block 8 to rewind the steel coil 13. Before the steel coil 13 is formed,The flexible steel plate is bent into an arc shape through the arc plate 10 and the top plate 11. When the arc block 8 rotates one circle, the end clamped by the electric clamp 9 corresponds to the tail position of the steel coil 13. The knob 32 is manually rotated. At this time, the threaded rod 31 rotates and extends toward the arc plate 10 under the action of the knob 32. Since one end of the threaded rod 31 is rotatably connected to the swivel 30, the top plate 11 moves upward to squeeze the surface of the steel coil 13. When the tail of the formed steel coil 13 corresponds to the weld distance and weld position of the end clamped by the electric clamp 9, compared with the traditional use of a rolling device to roll the steel coil 13, the device can be directly rolled and formed on the welding device at one time, without the need to use a rolling device to form the steel coil 13, and there is no need to place it through a lifting device, thereby avoiding the situation where the welding position of the steel coil 13 and the welding device position are misaligned. The steps of lifting and placing the steel coil 13 are reduced in the production process, thereby improving the laser welding head 16 for the steel coil 13. The welding speed is improved, and the welding efficiency of the laser welding head 16 to the steel coil 13 is also improved; when welding the steel coil 13, the intelligent remote control car 36 travels at a constant speed, carrying the arc heating device 40 and the laser welding head 16 to move at a constant speed. The arc heating device 40 first performs rapid electromagnetic heating on the position of the weld of the steel coil 13, and then the laser welding head 16 welds the weld of the heated part. At this time, the arc heating device 40 and the laser welding head 16 move to fully heat and weld the weld of the steel coil 13. After the welding is completed, the intelligent remote control car 36 is reset. At this time, the laser welding head 16 stops working and follows the reset of the intelligent remote control car 36. The arc heating device 40 still works during the reset process to heat the welded steel coil 13, preventing the weld of the welded steel coil 13 from being affected by the temperature and causing thermal expansion and contraction, avoiding cold cracks at the weld of the steel coil 13, thereby improving the welding quality of the laser welding head 16 to the steel coil 13.

[0031] Example 2: Please refer to Figure 1 - Fig.12, combined with the basis of embodiment 1, the difference is that a plurality of brackets 41 are fixedly installed on the surface of the base 1, and a rotating plate 42 is rotatably connected between any two brackets 41, and a roller 44 is rotatably connected to the bottom surface of any rotating plate 42, and a rotating seat 45 is fixedly installed on the top surface of any rotating plate 42, and a rotating column 46 matching with it is rotatably connected inside the rotating seat 45, and a roller 47 is rotatably connected to the surface of the rotating column 46, and a connecting rod 48 is fixedly installed on the surface of any rotating plate 42, and a plurality of rotating plates 42 are fixedly connected by the connecting rod 48, and the first outer ring 5 and the second outer ring 7 correspond to the positions of the brackets 41, and the electric telescopic rod 33 is retracted with the lifting frame 3 The formed steel coil 13 moves downward, and when the surface of the steel coil 13 contacts the roller 44, as the lifting frame 3 continues to move downward, the turn plate 42 rotates to make the roller 47 contact the surface of the steel coil 13, and the roller 47 fixes the steel coil 13 again before welding to ensure the stability of the steel coil 13 during the welding process. When the laser welding head 16 completes the welding of the steel coil 13, it extends from the material trough 49 through an external clamping device, and then clamps the welded steel coil 13. Subsequently, the electric clamp 9 does not clamp the steel coil 13. At this time, the clamping device pulls the steel coil 13 outward, and the welded steel coil 13 is taken out from the material trough 49, which facilitates the unloading of the welded steel coil 13.

[0032] A spring shaft 43 is arranged between the rotating plate 42 and the bracket 41. The spring shaft 43 is a conventional spring shaft 43 in the prior art. The rotating plate 42 is rotatably connected to the bracket 41 through the spring shaft 43. A material trough 49 for unloading the welded steel coil 13 is arranged between the second inner ring 6 and the second outer ring 7.

[0033] The use steps of the present invention are as follows: when the weld processing device with preheating and slow cooling functions is in use, the electric gripper 9 follows the arc block 8 to reel in the steel coil 13, and the threaded rod 31 rotates and extends toward the arc plate 10 under the action of the knob 32. Since one end of the threaded rod 31 is rotatably connected to the swivel 30, the top plate 11 moves upward to squeeze the surface of the steel coil 13. When the tail of the steel coil 13 is formed to correspond to the weld distance and weld position of the end clamped by the electric gripper 9, the electric telescopic rod 33 contracts and moves the lifting frame 3 downward, and the formed steel coil 13 moves downward. When the surface of the steel coil 13 contacts the roller 44, as the lifting frame 3 continues to move upward, the lifting frame 3 The rotating plate 42 rotates to make the roller 47 contact the surface of the steel coil 13. The roller 47 fixes the steel coil 13 again before welding to ensure the stability of the steel coil 13 during welding. When the laser welding head 16 completes welding of the steel coil 13, it extends from the material trough 49 through an external clamping device, and then clamps the welded steel coil 13. Subsequently, the electric clamp 9 does not clamp the steel coil 13. At this time, the clamping device pulls the steel coil 13 outward, and the welded steel coil 13 is taken out from the material trough 49. During the process of taking out the steel coil 13, the steel coil 13 is conveniently unloaded under the rotation of the roller 47 and the roller 44.
