Description

Technical Field

[0001] This utility model relates to the field of weld seam rolling technology, specifically to a weld seam rolling device. Background Technology

[0002] During welding, uneven heating and cooling can generate residual stress at the weld, affecting its mechanical properties. Simultaneously, the weld surface may exhibit unevenness and excessive weld reinforcement. Rolling can release stress at the weld and flatten and extend the arc-shaped weld metal outwards to counteract shrinkage stress, reducing weld crack susceptibility and the likelihood of cold cracking. It can also eliminate weld deformation and excessive reinforcement, resulting in a smooth weld surface. Existing weld rolling machines are typically designed for tubular and annular components, only capable of rolling welds in these shapes, and cannot roll welds on thin sheet steel strips. Current technology typically uses manual hammering for thin sheet steel strip welds; however, manual hammering is labor-intensive and cannot guarantee uniform force, resulting in poor surface finish and impacting production efficiency and product quality. Therefore, there is an urgent need for a device that can effectively solve these problems, ensuring uniform stress on the weld and creating a smooth, flat surface during the rolling of thin sheet steel strip welds. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a weld rolling device, which solves the technical problems of uneven stress and poor surface flatness of the weld when rolling thin steel strip welds in related technologies.

[0005] Mounting rack;

[0006] A support base, mounted on the mounting bracket, is used to support the workpiece;

[0007] A rolling assembly is slidably mounted on the mounting frame. The rolling assembly is movable along the length of the mounting frame. The rolling assembly can abut against the workpiece and move horizontally to roll the weld seam of the workpiece. The rolling assembly has a rolling wheel and an auxiliary wheel, which are coaxially arranged. The rolling wheel can abut against the workpiece and move horizontally to roll the weld seam of the workpiece. The auxiliary wheel can follow the rolling wheel to abut against the workpiece. The auxiliary wheel is used to adjust the rotation axis of the rolling wheel so that the rotation axis is parallel to the plane where the workpiece is located.

[0008] For example, at least one embodiment of this utility model provides a weld seam rolling device, wherein there are two auxiliary wheels, which are respectively located on both sides of the rolling wheel.

[0009] For example, at least one embodiment of this utility model provides a weld seam compaction device, wherein the compaction assembly further includes:

[0010] A bracket is slidably mounted on the mounting frame, and the bracket is capable of sliding along the length direction of the mounting frame.

[0011] A telescopic component is mounted on the bracket.

[0012] A mounting base is provided at the telescopic end of the telescopic component. Both the rolling wheel and the auxiliary wheel are rotatably mounted on the mounting base. The mounting base can move closer to or away from the support base under the drive of the telescopic component. When the mounting base moves closer to the support base, the rolling wheel can abut against the weld seam of the workpiece.

[0013] For example, at least one embodiment of this utility model provides a weld seam compaction device, wherein the support includes:

[0014] The protective plates are two in number and located on both sides of the auxiliary wheel. The two protective plates form a protective space, and the rolling wheel and the auxiliary wheel can rise into the protective space along with the telescopic member.

[0015] For example, at least one embodiment of this utility model provides a weld seam compaction device, wherein the mounting frame has a slider, and further includes:

[0016] A guide is disposed on the mounting frame, the guide is parallel to the length direction of the mounting frame, and the slider is slidably disposed on the guide.

[0017] For example, at least one embodiment of this utility model provides a weld seam compaction device, wherein the compaction assembly further includes:

[0018] A limiting wheel is rotatably mounted on the mounting base. The limiting wheel abuts against the auxiliary wheel. The limiting wheel can rotate with the auxiliary wheel. The plane containing the rotation axis of the limiting wheel and the rotation axis of the auxiliary wheel is perpendicular to the support base. The limiting wheel can limit the movement of the auxiliary wheel in the vertical direction.

[0019] For example, at least one embodiment of this utility model provides a weld seam compaction device, wherein the mounting frame includes:

[0020] A first frame, wherein the support base is disposed on the first frame;

[0021] The second frame is located above the first frame, and the guide is disposed on the second frame;

[0022] The column has several parts, and its two ends are respectively connected to the first frame and the second frame.

[0023] For example, at least one embodiment of the present invention provides a weld seam rolling device, including a driving member disposed on one side of the second frame, the driving member being used to drive the slider to move along the length direction of the mounting frame.

[0026] The beneficial effects of the embodiments of this utility model are as follows:

[0027] This invention, through the cooperation of a mounting frame, support base, and rolling assembly, changes the traditional method of manually hammering welds on thin steel strips. The support base positions and supports the workpiece, ensuring its stability during rolling and preventing uneven rolling caused by workpiece movement. The rolling assembly, compared to manual operation, ensures the linearity and stability of the rolling trajectory, resulting in more uniform pressure applied to the weld. The coaxial arrangement of the rolling wheel and auxiliary wheel allows the auxiliary wheel to sense the workpiece surface condition through contact. When the workpiece surface is tilted or uneven, the rotation axis of the rolling wheel will shift. By adjusting the auxiliary wheel, the rotation axis of the rolling wheel is aligned parallel to the plane of the workpiece. This ensures that the rolling wheel applies appropriate angle and pressure to the weld throughout the rolling process, effectively preventing uneven stress on the weld caused by improper rolling angles and improving the flatness and smoothness of the weld surface. Simultaneously, the equipment replaces manual operation, reducing labor intensity, increasing production efficiency, ensuring consistent processing quality, and improving product quality.

[0040] like Figures 1-4 The diagram illustrates a weld seam rolling device according to an embodiment of the present invention. It includes a mounting frame 1, a support base 11 fixedly mounted on a mounting base 25 for placing a thin steel strip workpiece, the surface of which contacts the bottom surface of the thin steel strip, providing stable support for the workpiece. A rolling assembly 2 is slidably mounted on the mounting frame 1 and is movable along the length of the mounting frame 1. A rolling wheel 21 and an auxiliary wheel 22 are coaxially rotatably mounted on the mounting base 25. In use, the thin steel strip workpiece is placed on the support base 11, and the rolling wheel 21 abuts against the weld seam of the workpiece. At this time, the auxiliary wheel 22 also contacts the surface of the workpiece and moves along the length of the mounting frame 1. During the process of contacting the weld seam and moving horizontally, the rolling wheel 21 performs a rolling operation on the weld seam. The auxiliary wheel 22 contacts the surface of the workpiece. When the surface of the workpiece is tilted or uneven, the rolling wheel 21 is adjusted by adjusting the auxiliary wheel 22, which causes the angle of the rotation axis of the rolling wheel 21 to change so that it is parallel to the plane of the workpiece, ensuring that the rolling wheel 21 can apply pressure to the weld evenly.

[0041] Specifically, the combination of mounting frame 1, support base 11, and rolling assembly 2 changes the traditional method of manually hammering welds on thin steel strips. Support base 11 positions and supports the workpiece, ensuring its stability during rolling and preventing uneven rolling caused by workpiece movement. Rolling assembly 2, by rolling the thin steel strip, ensures the straightness and stability of the movement trajectory during rolling compared to manual operation, allowing the rolling wheel 21 to apply more uniform pressure to the weld. The coaxial arrangement of rolling wheel 21 and auxiliary wheel 22 allows the auxiliary wheel 22 to sense the workpiece surface condition through contact. When the workpiece surface is tilted or uneven, the rotation axis of rolling wheel 21 will shift. By adjusting the auxiliary wheel 22, the rotation axis of rolling wheel 21 is aligned parallel to the plane of the workpiece. This ensures that rolling wheel 21 always applies appropriate angle and pressure to the weld throughout the rolling process, effectively avoiding uneven stress on the weld caused by improper rolling angle and improving the flatness and smoothness of the weld surface. At the same time, the equipment replaces manual operation, reducing labor intensity, improving production efficiency, ensuring consistent processing quality, and enhancing product quality.

[0042] like Figures 2-3 As shown, there are two auxiliary wheels 22, located on both sides of the rolling wheel 21. The support 23, telescopic member 24, and mounting base 25 of the rolling assembly 2 work together. The telescopic member 24 is fixedly mounted on the support 23, and the mounting base 25 is connected to the telescopic end of the telescopic member 24. Both the rolling wheel 21 and the auxiliary wheels 22 are rotatably mounted on the mounting base 25. When the equipment is running, the thin steel strip workpiece is placed on the support base 11. The telescopic member 24 extends, causing the mounting base 25 to move the rolling wheel 21 and auxiliary wheels 22 closer to the workpiece. The two auxiliary wheels 22 contact the two sides of the workpiece weld surface. When the rolling wheel 21 applies pressure to the weld and moves horizontally to roll it, the two auxiliary wheels 22 simultaneously sense the workpiece surface condition from both sides. When the rolling wheel 21's axis of rotation shifts due to rolling a relatively protruding weld, the rotation axis of the rolling wheel 21 is adjusted to return it to the correct position, ensuring that the rolling wheel 21 rolls the weld uniformly at an angle parallel to the workpiece plane. When the equipment stops working or requires maintenance, the telescopic component 24 retracts, causing the mounting base 25 to rise. The two auxiliary wheels 22 enhance the stability and accuracy of adjusting the rotation axis of the rolling roller 21. Compared to a single auxiliary wheel 22, it can more precisely handle complex conditions on the workpiece surface, ensuring that the rolling roller 21 always acts on the weld at the optimal angle. This further improves the stability and reliability of the equipment operation.

[0043] like Figure 2As shown, the protective space 2311 formed by the two protective plates 231 of the bracket 23 provides physical protection for the rolling wheel 21 and the auxiliary wheel 22. When the telescopic component 24 drives the mounting base 25 to rise, the rolling wheel 21 and the auxiliary wheel 22 are completely inserted into the protective space 2311. The protective plates 231 can prevent external debris and dust from falling into the rotating parts of the rolling wheel 21 and the auxiliary wheel 22, avoiding problems such as component wear and jamming caused by foreign objects entering. This effectively reduces the probability of equipment failure caused by external factors, ensures long-term stable operation of the equipment, reduces the frequency and difficulty of equipment maintenance, and further improves the practicality and durability of the equipment.

[0044] like Figures 1-4 As shown, the slider 12 on the mounting frame 1 cooperates with the guide member 13. The guide member 13 is mounted on the mounting frame 1 and parallel to the length direction of the mounting frame 1. The guide member 13 is preferably a screw slider 12 structure, but it can also be a mechanical mechanism that can achieve translation, such as an electric guide rail. There is no limitation here. The slider 12 is slidably connected to the guide member 13, and the bracket 23 of the rolling assembly 2 is fixedly connected to the slider 12. During the operation of the equipment, the slider 12 slides along the guide member 13, driving the rolling assembly 2 to move smoothly along the length direction of the mounting frame 1. The guide member 13 provides precise guidance for the slider 12, ensuring the straightness and stability of the rolling assembly 2's movement trajectory. Compared with a structure without a guide, it can effectively avoid problems such as deviation and shaking of the rolling assembly 2 during movement, allowing the rolling wheel 21 to perform rolling operations on the weld more accurately, improving the processing quality and consistency of the weld, while reducing vibration during equipment operation, reducing component wear caused by vibration, and extending the overall service life of the equipment.

[0045] like Figure 3 As shown, a limiting wheel 26 is rotatably mounted on the mounting base 25. The limiting wheel 26 abuts against the auxiliary wheel 22, and the plane containing the rotation axis of the limiting wheel 26 and the rotation axis of the auxiliary wheel 22 is perpendicular to the support base 11. When the auxiliary wheel 22 adjusts the rotation axis of the rolling wheel 21, the limiting wheel 26 rotates with the auxiliary wheel 22, while restricting the vertical movement of the auxiliary wheel 22. When rolling the weld seam of thin steel strip, if the uneven surface of the workpiece causes uneven force on the auxiliary wheel 22 and a tendency for vertical displacement, the limiting wheel 26 can promptly prevent this displacement, ensuring that the auxiliary wheel 22 is always in a suitable working position. This allows the auxiliary wheel 22 to more stably adjust the rotation axis of the rolling wheel 21, ensuring that the rolling wheel 21 applies uniform and stable pressure to the weld seam. This structural design improves the stability and reliability of the auxiliary wheel 22, further enhances the adaptability of the equipment to workpieces with different flatness, and improves the weld seam rolling effect and processing quality.

[0046] like Figure 1As shown, the mounting frame 1 consists of a first frame 14, a second frame 15, and several columns 16. The two ends of each column 16 are connected to the first frame 14 and the second frame 15, respectively. A support base 11 is mounted on the first frame 14, and a guide member 13 is mounted on the second frame 15. A drive member 3 is located on one side of the second frame 15, and its output end is connected to a slider 12. In use, a thin steel strip is placed on the support base 11 and positioned by the limiting member 111. Then, the telescopic member 24 is activated to bring the rolling wheel 21 and auxiliary wheel 22 into contact with the workpiece. At this time, the drive member 3 operates, driving the slider 12 to slide along the guide member 13 on the second frame 15, thereby moving the rolling assembly 2 along the length of the mounting frame 1. The first frame 14, the second frame 15, and the columns 16 constitute a stable mounting frame 1 structure, providing a reliable mounting foundation for components such as the support base 11 and the guide member 13, ensuring the overall structural strength and stability of the equipment. The drive component 3 enables automated control of the movement of the compaction assembly 2. Compared with manual pushing of the compaction assembly 2, the drive component 3 can more accurately control the movement speed and displacement of the compaction assembly 2, making the compaction process more stable and efficient. This not only reduces labor intensity but also improves production efficiency and the consistency of weld processing quality.

[0047] like Figure 3 As shown, several limiting members 111 on the support base 11 abut against the side of the thin steel strip workpiece to limit the workpiece. When placing the workpiece, the thin steel strip is placed on the support base 11, and the workpiece position is adjusted so that the side of the workpiece fits against the limiting members 111, thereby completing the horizontal positioning of the workpiece. The setting of the limiting members 111 ensures that the workpiece will not undergo horizontal displacement during the rolling process, providing a stable rolling object for the rolling wheel 21 and the auxiliary wheel 22. Combined with the structural design of the rolling assembly 2, when the rolling wheel 21 rolls the weld, because the workpiece position is fixed, the rolling wheel 21 can act on the weld at an accurate position and angle. The auxiliary wheel 22 can also better cooperate to adjust the rotation axis of the rolling wheel 21, ensuring uniform force on the weld, improving the flatness and smoothness of the weld surface, avoiding rolling deviations and quality problems caused by workpiece displacement, and improving the processing accuracy of the equipment and the product quality.

[0048] like Figure 3As shown, a return element 27 is provided on the protective plate 231. It is rotatably mounted on the protective plate 231. The return element 27 can translate along the rotation axis of the auxiliary wheel 22 and can return the auxiliary wheel 22 and the rolling wheel 21 that have deviated. The return element 27 is preferably a bolt and is threadedly connected to the protective plate 231. When the rolling wheel 21 is rolling the weld of the workpiece, if the rolling wheel 21 deviates due to a relatively protruding weld on the surface of the workpiece, the auxiliary wheel 22 and the rolling wheel 21 can be retracted into the protective space 2311 after the equipment is stopped. By rotating the return element 27 to press against the auxiliary wheel 22, the auxiliary wheel 22 and the rolling wheel 21 can be returned to the correct position. The setting of the return element 27 enables the rolling wheel 21 to be quickly returned to the correct position when it deviates, avoiding equipment disassembly caused by the deviation of the auxiliary wheel 22, reducing the maintenance work of the operator, and improving work efficiency.
