Description

Technical Field

[0001] This invention relates to the technical field of steel strip production equipment for casting machines, and particularly to a steel strip welding device for casting machines. Background Technology

[0002] The processing technology for copper wire rods both domestically and internationally is the continuous casting and rolling production line for copper wire rods. The casting machine in the continuous casting and rolling production line is a double-belt continuous casting machine, which uses casting machine steel strips.

[0003] Traditional casting machine steel strip raw materials are rectangular plate structures, and their welding method is I-type welding. However, the I-type welding method has defects in use. Therefore, the casting machine steel strip raw materials are cut into parallelograms and then oblique I-type welding is performed. The oblique I-type welding method increases the welding strength of the steel strip due to the increased butt joint length, thereby enhancing the service life of the steel strip. In addition, this method also ensures good contact between the steel strip and the pulley when the steel strip joint rotates to the pulley, thus ensuring the normal operation of the casting machine.

[0004] While oblique I-shaped welding is advantageous, the steel strip used in casting machines requires manual transport to a rolling mill to be rolled into a cylindrical structure, followed by manual removal and finally manual oblique I-shaped welding at the welding equipment. This process is cumbersome and inefficient. Therefore, we propose a steel strip welding device for casting machines. Summary of the Invention

[0020] 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.

[0021] Example: Reference Figures 1-9 The steel strip welding device for a casting machine shown may include a machine body 1 and a shaping welding device 100.

[0022] The machine body 1 has a working cavity 11 on its surface, and the bottom wall of the working cavity 11 has a groove 12.

[0023] The shaping and welding device 100 includes a center roller assembly 2, a shaping assembly 3, a welding assembly 4, a material ejection ring 5, multiple sets of pneumatic push rods 6, and a controller 7.

[0024] The central roller assembly 2 is disposed on the surface of the machine body 1 and located inside the working chamber 11. The shaping assembly 3 is disposed on the inner wall of the working chamber 11 and located outside the central roller assembly 2. The welding assembly 4 is disposed on the surface of the machine body 1 and located on one side of the top of the central roller assembly 2. The ejector ring 5 is slidably connected to the surface of the central roller assembly 2. Multiple sets of pneumatic push rods 6 are disposed on the surface of the machine body 1 and are respectively connected to one end of the shaping assembly 3, one end of the welding assembly 4 and one end of the ejector ring 5. The controller 7 is disposed on the surface of the machine body 1 and is electrically connected to the central roller assembly 2, the shaping assembly 3, the welding assembly 4, the ejector ring 5 and the multiple sets of pneumatic push rods 6.

[0025] As a preferred embodiment of this example, Figures 1-3 and Figure 5 As shown, the center roller assembly 2 may include a roller body 21 and a first motor 22.

[0026] The roller body 21 is rotatably connected to the surface of the machine body 1, the first motor 22 is bolted to the other side of the machine body 1 and connected to one end of the central shaft of the roller body 21, the first motor 22 is electrically connected to the controller 7, and the unloading ring 5 is slidably connected to the surface of the roller body 21.

[0027] It should be noted that weld marks are set on the surface of the roller body 21 at the corresponding position of the weld. The accuracy of the welding position is determined by setting the marks.

[0028] It should be noted that a speed reducer (not shown in the figure) is provided between the roller 21 and the first motor 22. By setting the speed reducer to reduce the rotation speed of the roller 21, the welding accuracy is improved and the effect is good.

[0029] In this embodiment, during use, the controller 7 controls the first motor 22 to be powered on and run. After the first motor 22 is powered on and rotates, it is reduced in speed by the reducer and synchronously drives the roller 21 to rotate. The rotation of the roller 21 synchronously drives the casting machine steel strip, which has been shaped into a cylindrical structure, to rotate. The welding operation can be achieved by adjusting the rotation speed of the casting machine steel strip and the position of the welding head 44.

[0030] As a preferred embodiment of this example, Figures 1-3 As shown, the shaping component 3 may include an arc-shaped lifting seat 31, multiple sets of shaping balls 32, an arc-shaped side fixing seat 33, and an arc-shaped pressing seat 34.

[0031] Among them, the arc-shaped lifting seat 31 is slidably connected to the inner wall of the groove 12, and multiple sets of shaping balls 32 and arc-shaped side fixed seats 33 are slidably connected to the inner wall of the working cavity 11 and are arranged vertically. The multiple sets of shaping balls 32 and arc-shaped side fixed seats 33 are all located on the outer side of the roller body 21. The arc-shaped lower pressure seat 34 is slidably connected to the surface of the machine body 1 and is located on one side of the top of the roller body 21. One end of the arc-shaped lifting seat 31, multiple sets of shaping balls 32, arc-shaped side fixed seats 33 and arc-shaped lower pressure seat 34 are respectively connected to one end of the pneumatic push rod 6.

[0032] In this embodiment, during use, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped lifting seat 31 to operate with air. The pneumatic push rod 6 drives the arc-shaped lifting seat 31 and the casting machine steel strip to move upward synchronously. When the casting machine steel strip contacts the bottom of the roller body 21, under the pressure of the arc-shaped portion 200 on the surface of the arc-shaped lifting seat 31, its two ends bend inward. Then, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped side fixing seat 33 to operate with air. The pneumatic push rod 6 drives the two sets of arc-shaped side fixing seats 33 to move inward synchronously. Under the pressure of the arc-shaped portion 200 on the surface of the two sets of arc-shaped side fixing seats 33, its two ends bend further inward and stick tightly to the surface of the roller body 21. Since the shape of the casting machine steel strip is a parallelogram, the two sets of arc-shaped side fixing seats 33 cannot directly press to the weld position. The shaping ball 32 needs to perform the pressing operation in sequence to align the weld. During use, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped lifting seat 31 to operate with air. The controller 7 controls the pneumatic push rod 6 corresponding to the position of the shaping ball 32 to circulate air. The shaping ball 32 on the left extends outward in sequence and squeezes the surface of the casting machine steel strip to make it fit against the surface of the roller body 21. The shaping ball 32 on the right extends outward in sequence and squeezes the surface of the casting machine steel strip to make it fit against the surface of the roller body 21. After all the shaping balls 32 have extended, there is a set gap between them. The shape of this gap is adapted to the outer dimensions of the weld and the arc-shaped part 200 at the bottom of the arc-shaped lower pressure seat 34. Then, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped lower pressure seat 34 to circulate air. The pneumatic push rod 6 circulates air and drives the arc-shaped lower pressure seat 34 to descend. The descent of the arc-shaped lower pressure seat 34 drives the arc-shaped part 200 at its bottom to press down on both ends of the casting machine steel strip, aligning the two ends and making them completely fit against the surface of the roller body 21 to form a cylindrical structure. The above operation completes the shaping operation and has a good effect.

[0033] As a preferred embodiment of this example, Figure 3 As shown, the surfaces of the arc-shaped lifting seat 31, the arc-shaped side fixing seat 33, and the arc-shaped lower pressing seat 34 are respectively provided with arc-shaped portions 200 that are adapted to the outer dimensions of the roller body 21.

[0034] Among them, the arc-shaped part 200 at the bottom of the arc-shaped pressure seat 34 corresponds to the weld position.

[0035] It should be noted that the arc-shaped part 200 at the bottom of the arc-shaped pressure seat 34 is adapted to the outer dimensions of the weld.

[0036] In this embodiment, the arc-shaped part 200 is provided to facilitate the direct extrusion of the steel strip of the casting machine into a cylindrical structure. The arc-shaped part 200 at the bottom of the arc-shaped lower pressure seat 34 corresponds to the weld position and is compatible in shape and size, which facilitates direct extrusion at the weld, so that both ends of the steel strip of the casting machine fit perfectly with the surface of the roller body 21, leaving only a set spacing weld, which facilitates subsequent welding operations.

[0037] As a preferred embodiment of this example, Figures 1-4 As shown, the welding assembly 4 may include a slide 41, a threaded screw 42, a slide block 43, a welding head 44, and a second motor 45.

[0038] The slide 41 is slidably connected to the surface of the machine body 1 and located between the arc-shaped lower pressure seat 34 and the roller body 21. The threaded screw 42 is rotatably connected to the inner wall of the slide 41. The slide seat 43 is threadedly connected to the outer surface of the threaded screw 42 and slidably connected to the inner wall of the slide 41. The welding head 44 is located at the bottom of the slide seat 43. One end of the slide 41 extends through the other side surface of the machine body 1 and is fixedly connected to a second motor 45. The second motor 45 is connected to one end of the threaded screw 42 and is electrically connected to the controller 7. The end of the slide 41 that extends through the other side surface of the machine body 1 is connected to one end of the pneumatic push rod 6.

[0039] It should be noted that an encoder (not shown in the figure) is provided on the surface of the second motor 45. The encoder is used to detect the number of rotations of the second motor 45 in real time and send the data information to the controller 7. The controller 7 determines the position of the slide 43 on the surface of the threaded screw 42 based on the number of rotations, thereby knowing the specific position of the welding head 44.

[0040] It should be noted that the bottom of the welding head 44 is on the same plane as the upper surface of the steel strip of the casting machine. By limiting the height of the bottom of the welding head 44, it can be moved directly to the welding point after translation, without the need for further height adjustment, resulting in good performance.

[0041] It should be noted that the surface of the body 1 is provided with a strip-shaped guide groove to facilitate the sliding of the carriage 41.

[0042] In this embodiment, during use, the controller 7 controls the pneumatic push rod 6 to operate, which in turn moves the slide 41 and welding head 44 directly to the welding point. Then, the controller 7 controls the second motor 45 to operate, and the rotation of the second motor 45 synchronously drives the threaded screw 42 to rotate. The rotation of the threaded screw 42 synchronously drives the slide 43 to move to one side, and the movement of the slide 43 synchronously drives the welding head 44 to move. During this process, the controller 7 synchronously controls the first motor 22 to operate and the welding head 44 to run. The rotation of the first motor 22 is reduced by the reducer. After speeding up, the roller 21 is driven to rotate synchronously. The rotation of the roller 21 synchronously drives the casting machine steel strip, which has been shaped into a cylindrical structure, to rotate. The welding head 44 runs to perform welding operations at the weld seam. By adjusting the rotation speed of the casting machine steel strip and the position of the welding head 44, the oblique welding operation can be achieved. The encoder on the surface of the second motor 45 is used to detect the number of rotations of the second motor 45 in real time and send the data information to the controller 7. The controller 7 determines the position of the slide 43 on the surface of the threaded screw 42 based on the number of rotations, thereby knowing the specific position of the welding head 44.

[0043] As a preferred embodiment of this example, Figures 1-3 As shown, a U-shaped positioning block 300 is provided on the inner wall of the working cavity 11 and is located outside the groove 12.

[0044] In this embodiment, a U-shaped positioning block 300 is provided to facilitate the positioning of the pre-cut parallelogram-shaped steel strip of the casting machine, thereby improving installation efficiency and ensuring positioning accuracy.

[0045] As a preferred embodiment of this example, Figures 6-9 As shown, it also includes a pneumatic loading and unloading device 8, which may include a loading mechanism 81, an unloading mechanism 82, and a pneumatic magnetic suction mechanism 83.

[0046] The feeding mechanism 81 is set on the surface of the machine body 1, the unloading mechanism 82 is set on the ground and located on one side of the feeding mechanism 81, the pneumatic magnetic suction mechanism 83 is set on the surface of the unloading mechanism 82 and is on the same axis as the central roller assembly 2. One end of the pneumatic magnetic suction mechanism 83 is slidably connected to the surfaces of the feeding mechanism 81 and the unloading mechanism 82 respectively. The feeding mechanism 81 and the pneumatic magnetic suction mechanism 83 are electrically connected to the controller 7 respectively.

[0047] In this embodiment, the pneumatic loading and unloading device 8 effectively replaces manual loading and unloading operations, improving work efficiency and reducing labor intensity.

[0048] As a preferred embodiment of this example, Figures 6-8 As shown, the feeding mechanism 81 may include a feeding box 811, a guide push groove 812, a strip discharge groove 813, a recess 814, a hydraulic telescopic column 815, and a lifting seat 816.

[0049] The feeding box 811 is located on the surface of the machine body 1, the guide push groove 812 is opened on the top of the feeding box 811, the strip discharge groove 813 is opened on the surface of the feeding box 811, the pit 814 is opened on the ground and corresponds to the position of the feeding box 811, the hydraulic telescopic column 815 is located inside the pit 814 and is electrically connected to the controller 7, and the lifting seat 816 is located on the top of the hydraulic telescopic column 815 and is located inside the feeding box 811.

[0050] It should be noted that the position of the strip discharge chute 813 corresponds to the position of the U-shaped positioning block 300. The lifting seat 816 is flush with the ground in the initial state. A limit guide groove is opened on the top of the lifting seat 816, and a fixing component is provided on the inner wall of the limit guide groove. The limit guide groove is used to guide and position the material seat loaded with parallelogram casting machine steel strip, and the fixing component is used to fix the material seat.

[0051] In this embodiment, the structure and connection relationship of the feeding mechanism 81 are further described. In use, the material seat loaded with parallelogram casting machine steel strips is moved along the limiting guide groove to the lifting seat 816, and finally fixed by the fixing component. After fixing, the controller 7 controls the operation of the hydraulic telescopic column 815. The operation of the hydraulic telescopic column 815 drives the lifting seat 816 to rise and move into the feeding box 811 until the uppermost set of parallelogram casting machine steel strips on the material seat corresponds to the position of the strip discharge groove 813. After the uppermost set of parallelogram casting machine steel strips is removed, the controller 7 controls the hydraulic telescopic column 815 to rise one position after a set time, so that the next set of parallelogram casting machine steel strips rises to the position corresponding to the position of the strip discharge groove 813, realizing automatic feeding operation. This is repeated until all the parallelogram casting machine steel strips on the material seat are removed.

[0052] As a preferred embodiment of this example, Figures 6-7 As shown, the feeding mechanism 82 may include a feeding frame 821, an arc-shaped extension 822, a semi-circular guide frame 823, and a limiting channel 824.

[0053] The unloading rack 821 is set on the ground and located on one side of the recess 814. The arc-shaped extension 822 is set on the surface of the unloading rack 821 and is connected to the interior of the unloading rack 821. The semi-circular guide rack 823 is symmetrically set on the top of the loading box 811 and located outside the guide push groove 812. There is a set space between the bottoms of the two sets of semi-circular guide racks 823, forming a limiting channel 824. The limiting channel 824 corresponds to the position of the guide push groove 812.

[0054] It should be noted that a conveyor belt mechanism can be installed at the discharge end of the unloading rack 821 to transport the steel belt of the casting machine.

[0055] In this embodiment, the structure and connection relationship of the feeding mechanism 82 are further explained. In use, the pneumatic magnetic attraction mechanism 83 magnetically attracts and fixes the casting machine steel strip still on the surface of the roller body 21. After being magnetically attracted and fixed, it is driven to detach from the surface of the roller body 21, so that it enters the arc-shaped extension 822 along the semi-circular guide frame 823, and then enters the feeding frame 821 from the arc-shaped extension 822 to realize the material discharge operation.

[0056] As a preferred embodiment of this example, Figures 6-9 As shown, the pneumatic magnetic suction mechanism 83 may include a loading / unloading pushing cylinder 831, a suction frame 832, a pushing frame 833, and an annular electromagnetic chuck 834.

[0057] The loading and unloading cylinder 831 is mounted on the surface of the unloading frame 821. The suction frame 832 and the pusher frame 833 are respectively mounted on the output end surface of the loading and unloading cylinder 831. The annular electromagnetic chuck 834 is mounted on the surface of the suction frame 832. The loading and unloading cylinder 831 and the annular electromagnetic chuck 834 are electrically connected to the controller 7. The suction frame 832, the arc-shaped extension 822, the semi-annular guide frame 823 and the central roller assembly 2 are all located on the same axis.

[0058] It should be noted that a position sensor is installed on the loading and unloading push cylinder 831 and is electrically connected to the controller 7. The position sensor is used to detect the position of the suction frame 832. When the suction frame 832 contacts the casting machine steel strip on the surface of the roller 21, the controller 7 will control the annular electromagnetic chuck 834 to be energized. When the suction frame 832 returns to the initial position, the controller 7 will control the annular electromagnetic chuck 834 to be de-energized.

[0059] In this embodiment, the structure and connection relationship of the pneumatic magnetic suction mechanism 83 are further described. During use, the controller 7 controls the loading / unloading push cylinder 831 to operate with airflow. The airflow of the loading / unloading push cylinder 831 causes its output end to move towards one side of the machine body 1. Simultaneously, the movement of its output end drives the suction frame 832 and the push frame 833 to move. During the movement, one end of the push frame 833 enters the loading box 811 through the guide groove 812, and drives the casting machine steel strip inside the loading box 811 to move through the strip discharge groove 813 to the inside of the U-shaped positioning block 300 to achieve loading. The suction frame 832... 32 moves to the outside of roller 21 and contacts the casting machine steel strip on the surface of roller 21. After contact, the annular electromagnetic chuck 834 is energized and magnetically fixed to the casting machine steel strip. Then, the controller 7 controls the loading and unloading pushing cylinder 831 to reset. The reset of the loading and unloading pushing cylinder 831 synchronously drives the suction frame 832 and the push frame 833 to reset. During the reset process, the suction frame 832 synchronously drives the casting machine steel strip to detach from the surface of roller 21, so that it enters the arc extension 822 along the semi-annular guide frame 823, and then enters the unloading frame 821 from the arc extension 822 to realize the discharge operation.

[0060] Working principle of this invention: In use, the material seat loaded with parallelogram-shaped casting machine steel strips is moved along the limiting guide groove to the lifting seat 816, and finally fixed by the fixing parts. After fixing, the controller 7 controls the operation of the hydraulic telescopic column 815. The operation of the hydraulic telescopic column 815 drives the lifting seat 816 to rise and move into the loading box 811 until the uppermost set of parallelogram-shaped casting machine steel strips on the material seat corresponds to the position of the strip discharge chute 813. (Subsequently, after the uppermost set of parallelogram-shaped casting machine steel strips moves out, the controller 7 controls the hydraulic telescopic column 815 to rise one position after a set time, so that the next set of parallelogram-shaped casting machine steel strips rises to the position corresponding to the position of the strip discharge chute 813, realizing automatic feeding operation. This process is repeated until the material seat has a parallelogram-shaped casting machine steel strip.) After all the steel strip of the quadrilateral casting machine has been removed, the controller 7 controls the loading and unloading push cylinder 831 to operate. The loading and unloading push cylinder 831 moves its output end towards one side of the machine body 1. The movement of its output end synchronously moves the suction frame 832 and the push frame 833. During the movement, one end of the push frame 833 enters the loading box 811 through the guide groove 812, and drives the steel strip of the casting machine inside the loading box 811 to move through the strip discharge groove 813 to the inside of the U-shaped positioning block 300 to achieve loading. The suction frame 832 moves to the outside of the roller body 21. Then the controller 7 controls the loading and unloading push cylinder 831 to reset. The reset of the loading and unloading push cylinder 831 synchronously drives the suction frame 832 and the push frame 833 to reset. After completion, controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped lifting seat 31 to operate. The pneumatic push rod 6 drives the arc-shaped lifting seat 31 and the casting machine steel strip to move upward synchronously. When the casting machine steel strip contacts the bottom of the roller body 21, under the pressure of the arc-shaped part 200 on the surface of the arc-shaped lifting seat 31, its two ends bend inward. Then, controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped side fixed seat 33 to operate. The pneumatic push rod 6 drives the two sets of arc-shaped side fixed seats 33 to move inward synchronously. Under the pressure of the arc-shaped part 200 on the surface of the two sets of arc-shaped side fixed seats 33, its two ends bend further inward and stick tightly to the surface of the roller body 21. Since the shape of the casting machine steel strip is a parallelogram, the two sets of arc-shaped side fixed seats 33 cannot directly press to the weld position. At this point, the shaping balls 32 need to be extruded sequentially to align the weld joint. During operation, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the shaping balls 32 to circulate air. The shaping balls 32 on the left extend sequentially from the inside to the outside, extruding and pressing the surface of the casting machine steel strip to make it adhere to the surface of the roller body 21. The shaping balls 32 on the right extend sequentially from the outside to the inside, extruding and pressing the surface of the casting machine steel strip to make it adhere to the surface of the roller body 21. After all the shaping balls 32 have extended, there is a set gap between them. The shape of this gap is adapted to the outer dimensions of the weld and the arc-shaped part 200 at the bottom of the arc-shaped lower pressure seat 34. Then, the controller 7 controls the pneumatic push rod 6 corresponding to the position of the arc-shaped lower pressure seat 34 to circulate air, and the pneumatic push rod 6 circulates air to drive the arc-shaped lower pressure seat 34 to descend.The arc-shaped lower pressure seat 34 descends, causing the arc-shaped part 200 at its bottom to descend to both ends of the die-casting machine steel strip, aligning the two ends and making them completely adhere to the surface of the roller body 21, forming a cylindrical structure. This completes the shaping operation, resulting in good performance. After the shaping operation is completed, the controller 7 controls the pneumatic push rod 6, corresponding to the position of the slide 41, to operate. The pneumatic push rod 6 simultaneously moves the slide 41 and welding head 44 directly to the welding point. Then, the controller 7 controls the second motor 45 to operate. The rotation of the second motor 45 simultaneously drives the threaded screw 42 to rotate. The rotation of the threaded screw 42 simultaneously moves the slide 43 to one side. The movement of the slide 43 simultaneously moves the welding head 44. During this process, the controller... The controller 7 synchronously controls the energization of the first motor 22 and the operation of the welding head 44. The first motor 22, after being energized and rotated, is reduced in speed by a reducer, synchronously driving the roller 21 to rotate. The rotation of the roller 21 synchronously drives the casting machine steel strip, which has been shaped into a cylindrical structure, to rotate. The operation of the welding head 44 performs welding operations at the weld seam. Oblique welding operations can be achieved by adjusting the rotation speed of the casting machine steel strip and the position of the welding head 44. The encoder on the surface of the second motor 45 is used to detect the number of rotations of the second motor 45 in real time and sends the data to the controller 7. The controller 7 determines the position of the slide 43 on the surface of the threaded screw 42 based on the rotation count data, thus determining the specific position of the welding head 44. After welding is completed, the controller 7 controls... After welding assembly 4 resets, controller 7 controls the pneumatic push rod 6, corresponding to the position of the ejector ring 5, to circulate air. The pneumatic push rod 6 moves the ejector ring 5 to one side, moving the casting machine steel strip fitted on the surface of roller 21 to a set position for easy unloading. After the ejector ring 5 moves the casting machine steel strip, it begins to reset. After the ejector ring 5 resets, controller 7 again controls the loading / unloading push cylinder 831 to circulate air. The loading / unloading push cylinder 831 moves its output end to one side of the machine body 1. Simultaneously, the movement of its output end moves the suction frame 832 and the pusher frame 833. During the movement, one end of the pusher frame 833 re-enters the loading box 811 through the guide groove 812. The steel strip inside the feeding box 811 is moved through the strip discharge chute 813 to the inside of the U-shaped positioning block 300 for feeding. The suction frame 832 moves to the outside of the roller body 21 and contacts the steel strip on the surface of the roller body 21. After contact, the annular electromagnetic chuck 834 is energized and magnetically fixed to the steel strip. Then, the controller 7 controls the loading and unloading push cylinder 831 to reset. The reset of the loading and unloading push cylinder 831 simultaneously drives the suction frame 832 and the push frame 833 to reset. During the reset process, the suction frame 832 simultaneously drives the steel strip to detach from the surface of the roller body 21, allowing it to enter the arc-shaped extension 822 along the semi-annular guide frame 823, and then enter the unloading frame 821 from the arc-shaped extension 822 to achieve the discharge operation.
