Description

Technical Field

[0001] This utility model relates to the field of flux-cored welding wire technology, specifically to a 620MPa-grade flux-cored welding wire forming device. Background Technology

[0002] With the widespread application of high-strength steel (≥620MPa grade) in energy equipment, heavy machinery, and chemical containers, higher requirements are placed on the performance consistency and manufacturing precision of supporting welding materials. Flux-cored welding wire, with its advantages of flexible and adjustable alloy composition and high deposition efficiency, has become a key material for welding high-strength steel structures.

[0003] Chinese patent document CN215546006U discloses a steel strip forming device for flux-cored welding wire. A drive motor rotates, which in turn drives a transmission shaft. The transmission shaft drives a driving bevel gear, while two driven bevel gears meshing with this driving bevel gear drive a first upper roller and a second upper roller to rotate synchronously in the same direction. The first upper roller, through a set of synchronous gears, drives a first lower roller to rotate synchronously in the opposite direction. The second upper roller, through another set of synchronous gears, drives a second lower roller to rotate synchronously in the opposite direction. This allows the first and second rollers, as well as the second and third upper rollers, to synchronously press the steel strip together. Furthermore, it allows the first and second roller groups to move closer together to reduce the overall size. Simultaneously, the first and second roller groups simultaneously roll the steel strip, ensuring that the steel strip is not stretched or squeezed, thus guaranteeing the quality of the formed steel strip.

[0004] However, in the above scheme, the drive shaft is located between two parallel lower rolls and is arranged perpendicular to them. The upper rolls are installed directly above the two lower rolls. During use, the drive shaft and the driving bevel gear and driven bevel gear on the lower rolls are placed eccentrically. Since the meshing connection of the bevel gears requires the axes to intersect at one point, the driving bevel gear and driven bevel gear cannot mesh, so the motor cannot drive the rotation of the upper and lower rolls, and thus the steel strip cannot be rolled.

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a 620MPa-grade flux-cored wire forming device.

[0027] like Figure 1-3 As shown, the present invention proposes a 620MPa grade flux-cored wire forming device, which includes a frame 1, rollers 4, nuts 5, shaft 10 and drive assembly;

[0028] There are multiple rollers 4, all of which are located on the side of the frame 1. The multiple rollers 4 are arranged in two rows, and the two rows of rollers 4 are connected by rolling. In use, the steel strip is conveyed through the two rows of rollers 4 while the rolling work is carried out.

[0029] The shaft 10 is rotatably mounted on the frame 1 and one end extends to the side of the frame 1 and is connected to the roller 4. The shaft 10 and the roller 4 are arranged in a one-to-one correspondence. One end of the shaft 10 and the side of the frame 1 is provided with a limiting block 11 that is connected to the side of the roller 4 and limits the rotation of the roller 4 in use.

[0030] Nut 5 is installed at the end of shaft 10 and is fitted and connected to roller 4, used to fix roller 4 and limit block 11 when connected to shaft 10;

[0031] The drive assembly is located at the top of the frame 1 and extends to the inside of the frame 1 to connect with the shaft 10. The side of the drive assembly is provided with a transmission component that connects to multiple shafts 10 and, in use, synchronizes and allows two rows of shafts 10 to rotate relative to each other.

[0032] In this embodiment, a shaft 10 is rotatably mounted on a frame 1, with one end extending to the side of the frame 1. A roller 4 is sleeved on one end of the shaft 10. Simultaneously, a nut 5 is installed on one end of the shaft 10 using a wrench, and the nut 5 applies axial force to the roller 4, causing the roller 4 to fit and engage with the limiting block 11. This fixes the roller 4 at one end of the shaft 10 between the nut 5 and the limiting block 11, limiting the mutual rotation between the roller 4 and the shaft 10. When the shaft 10 is rotated by the drive assembly, the transmission assembly drives the two rows of shafts 10 to rotate synchronously and in opposite directions, making the operation of the roller 4 smoother and the replacement of the roller 4 more convenient, so as to perform steel strip rolling work of different sizes. Example 2

[0033] like Figure 2 As shown, the present invention proposes a 620MPa grade flux-cored welding wire forming device. The difference between this embodiment and the first embodiment is that the transmission component includes a gear 8 and a second chain transmission component 9.

[0034] There are two gears 8, which are installed on the other end of two symmetrically arranged shafts 10 and are meshed with each other.

[0035] There are multiple second chain drive components 9, and multiple second chain drive components 9 are respectively installed at the other end of two adjacent shafts 10 in each row.

[0036] In this embodiment, multiple second chain drive components 9 are respectively connected to two adjacent rotating shafts in each row, so that multiple rotating shafts are interconnected by the second chain drive components 9, thereby causing multiple shafts 10 in each row to rotate synchronously. At the same time, by installing two gears 8 on the shafts 10 in one row respectively, and placing the gears 8 symmetrically and meshing with each other, when one row of shafts 10 rotates, the other row rotates in the opposite direction through the transmission action of the two gears 8, causing multiple rollers 4 to rotate in the opposite direction, thereby causing the rollers 4 to convey and roll the steel strip. Example 3

[0037] like Figure 3 As shown, the present invention proposes a 620MPa grade flux-cored welding wire forming device. Compared with the first embodiment, the difference in this embodiment is that one end of the shaft 10 is provided with a thread 6, and the nut 5 is connected to the shaft 10 through the thread 6. The tightening direction of the nut 5 is arranged in accordance with the rotation direction of the shaft 10 to avoid the nut 5 from becoming loose.

[0038] In an optional embodiment, a hexagonal block 7 is provided at one end of the shaft 10. The maximum size of the end face of the hexagonal block 7 is smaller than the diameter of the end face of the shaft 10. This is used to fit the roller 4 onto the shaft 10 from the outside of the hexagonal block 7 during use. A tool such as a wrench is connected to the hexagonal block 7, so that the tool limits the rotation of the shaft 10 through the hexagonal block 7. This allows the nut 5 to be connected to or separated from the thread 6 on the shaft 10, making the installation and removal of the nut 5 more convenient.

[0039] In this embodiment, the roller 4 is sleeved on one end of the shaft 10, and the rotation of the shaft 10 is limited by connecting it to the hexagonal block 7 with a wrench. At the same time, the nut 5 is installed on the shaft 10 through the thread 6 using a wrench. Simultaneously, the nut 5 applies axial force to the roller 4, making the roller 4 tightly attached to and locked with the limiting block 11, and fixing the roller 4 between the nut 5 and the limiting block 11. This allows the roller 4 to be detachably connected to the shaft 10, thereby enabling the roller 4 to be replaced for conveying and rolling steel strips of different widths and thicknesses. Example 4

[0040] like Figure 3 As shown, the present invention proposes a 620MPa grade flux-cored welding wire forming device. Compared with the first embodiment, the difference in this embodiment is that a plurality of limiting strips 13 are provided on the outer circular surface of one end of the shaft 10 and on the side of the limiting block 11. The plurality of limiting strips 13 are arranged at equal angles around the center of the shaft 10. A limiting groove 15 is provided in the middle of the roller 4. The limiting strips 13 are located inside the limiting groove 15. During use, the limiting strips 13 and the inner wall of the limiting groove 15 generate an interaction force, thereby limiting the mutual rotation between the roller 4 and the shaft 10 and improving the connection stability between the roller 4 and the shaft 10.

[0041] In an optional embodiment, the side of the limiting block 11 is provided with a connecting groove 12, and the side of the roller 4 is provided with a rectangular block 14. When the roller 4 and the limiting block 11 are installed together, the rectangular block 14 is accommodated in the connecting groove 12. This allows the rectangular block 14 to be inserted into the connecting groove 12 when the roller 4 contacts the limiting block 11, so that the rectangular block 14 and the inner wall of the connecting groove 12 generate an interaction force, further improving the stability of the roller 4 during installation and use. Example 5

[0042] like Figure 1-2 As shown, the present invention proposes a 620MPa grade flux-cored welding wire forming device. The difference between this embodiment and the first embodiment is that the driving component includes a motor 2 and a first chain drive component 3.

[0043] Motor 2 is mounted on the top of frame 1;

[0044] The first chain drive 3 is mounted on the output shaft of the motor 2 and one end extends to the inner side of the frame 1 and is connected to the shaft 10. In use, the output shaft of the motor 2 can be connected to a reducer, and the first chain drive 3 is connected to the output shaft of the reducer, so that the speed at which the first chain drive 3 drives the shaft 10 to rotate is reduced. The use of the reducer connected to the motor is existing technology and is not shown in the figure.

[0045] In this embodiment, the first chain drive 3 is connected to the output shaft and shaft body 10 of the motor 2 respectively. When the motor 2 starts, the shaft body 10 is rotated by the first chain drive 3.

[0046] In this invention, multiple shafts 10 are arranged side-by-side in two symmetrical rows, with their ends extending to the side of the frame 1. A roller 4 is fitted onto one end of the shaft 10, and a limiting block 11 limits the position of the roller 4. Simultaneously, the roller 4 drives the limiting groove 15 to wrap around the outside of the limiting strip 13, and the connecting groove 12 is inserted into the rectangular block 14, thus limiting the mutual rotation between the roller 4 and the shaft 10. A nut 5 is fitted onto the end of the shaft 10 and connected to the thread 6. At the same time, a wrench is connected to a hexagonal block 7 to limit the rotation of the shaft 10. The wrench is used to continue to tighten the nut 5, pressing it tightly against the side of the roller 4. This, in turn, allows the nut 5 and the limiting block 11 to engage the roller. 4 is detachably fixed to the shaft 10, allowing the roller 4 to be replaced. The roller 4 can convey and roll steel strips of different widths and thicknesses. At the same time, the motor 2 is started to drive the first chain drive 3 to rotate, which in turn drives the shaft 10 to rotate. The second chain drive 9 connects two adjacent shafts in each row, so that multiple shafts 10 in each row rotate synchronously and in the same direction. At the same time, two gears 8 mesh on two symmetrically arranged shafts 10, and the transmission action of the two gears 8 drives the two rows of shafts 10 to rotate synchronously and in opposite directions. This causes the two rows of shafts 10 to drive the two rows of rollers 4 to rotate synchronously and in opposite directions, so that the two rows of rollers 4 convey the steel strip and roll it into shape during the conveying process.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
