Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe bending technology, specifically a U-shaped clamp pipe bending tool. Background Technology
[0002] U-shaped pipes are widely used in industrial manufacturing, infrastructure construction, and other fields due to their unique structure and performance. Among them, U-shaped clamp pipes, as a special type of U-shaped pipe, are often used to fasten and connect various pipe fittings and equipment. Their clamp structure provides reliable clamping force, ensuring the stable operation of related components. Furthermore, in practical applications, U-shaped clamp pipes need to undergo further bending processing to meet specific installation and usage requirements.
[0003] Chinese utility model patent CN217165967U discloses a U-shaped pipe bending device, which can directly press straight pipes into the required U-shape without subsequent cutting processes. It also boasts high processing speed and efficiency, while saving pipe material and reducing processing costs. However, U-shaped clamp pipes have two side walls, a unique structural feature that makes them prone to interference with traditional bending equipment during bending, leading to deformation or damage to the side walls. Furthermore, existing bending fixtures have poor versatility and cannot meet the U-shaped opening size requirements of U-shaped clamp pipes.
[0004] Therefore, there is an urgent need for a bending tool for U-shaped clamp pipes to prevent the direct extrusion and interference of traditional bending methods on the side wall of U-shaped clamp pipes, reduce the probability of pipe damage, and ensure the convenience of operation and bending efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a bending fixture for U-shaped clamp pipes, so as to solve at least one aspect of the problems and defects mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A bending fixture for U-shaped clamp pipes, comprising:
[0008] The workpiece to be processed and the worktable, wherein a mounting plate is provided on one side of the top of the worktable;
[0009] A rotating mechanism is movably provided on one side of the mounting plate.
[0010] A bending mechanism is rotatably provided in the middle of the rotating mechanism, and a groove is provided along the outer wall of the bending mechanism. The width of the groove is adapted to the thickness of the side wall of the mounting plate.
[0011] The rotating mechanism can drive the bending mechanism to rotate along the side wall of the mounting plate;
[0012] The workpiece to be processed is engaged between the side wall of the mounting plate and the groove.
[0013] The U-shaped clamp pipe bending fixture according to this scheme has at least the following technical effects:
[0014] In use, the inner wall of the U-shaped clamp tube to be processed is fitted onto one side wall of the mounting plate, and the U-shaped clamp tube is engaged between the side wall of the mounting plate and the groove of the bending mechanism. At this time, the rotating mechanism is rotated, and the bending mechanism rolls along the side wall of the mounting plate under the drive of the rotating mechanism. As the rotation angle of the rotating mechanism changes, the bending mechanism rolls from one side of the mounting plate to the adjacent side, thereby bending the U-shaped clamp tube between the side wall of the mounting plate and the groove.
[0015] This U-shaped clamp pipe bending fixture can effectively clamp the U-shaped clamp pipe between the side wall of the mounting plate and the groove of the bending mechanism for positioning and limiting. Under the rotation of the rotating mechanism, a roll bending method is used to drive the bending mechanism to roll along the side wall of the mounting plate. As the rotation angle of the rotating mechanism changes, the bending mechanism rolls from one side of the mounting plate to the adjacent side, thereby bending the U-shaped clamp pipe between the side wall of the mounting plate and the groove. This effectively prevents the direct squeezing interference of traditional bending methods on the side wall of the U-shaped clamp pipe, reduces the probability of pipe damage, and eliminates the need for re-bending. The simplified adjustment and additional fixing steps reduce the operational difficulty and improve the flexibility and convenience of bending U-shaped clamps, ensuring the bending quality and efficiency of U-shaped clamps. Simultaneously, the bending angle of the U-shaped clamp can be determined based on the angle between two adjacent sidewalls of the mounting plate, making the bending angle range of the U-shaped clamp wider. Furthermore, after one end of the U-shaped clamp is bent, it can be removed, and the other end can be bent again to achieve the U-shape bending operation, meeting different usage requirements of the U-shaped clamp.
[0016] As a further embodiment of this utility model: the rotating mechanism includes a long plate, the long plate is provided with an upper support plate and a lower support plate, and the mounting plate is disposed in the cavity between the upper support plate and the lower support plate.
[0017] As a further embodiment of this utility model, a first rotating shaft and a second rotating shaft are provided through the upper support plate, the mounting plate and the lower support plate.
[0018] As a further embodiment of this utility model: the mounting plate is provided with an arc-shaped groove, and the first rotating shaft is disposed through the arc-shaped groove and rotates along the arc-shaped groove.
[0019] As a further embodiment of this utility model: the rotation mechanism is limited to rotating at an angle of 0°-90° along the arc-shaped groove via the first rotating shaft.
[0020] As a further embodiment of this utility model: the rotating mechanism drives the bending mechanism to roll along the side wall of the mounting plate with the second rotating shaft as the center.
[0021] The rotating mechanism includes a long plate with an upper support plate and a lower support plate. A mounting plate is positioned within the cavity between the upper and lower support plates. A first rotating shaft and a second rotating shaft are installed through the upper support plate, the mounting plate, and the lower support plate. An arc-shaped groove is provided on the mounting plate. The first rotating shaft passes through the arc-shaped groove and rotates along it. The rotating mechanism rotates along the arc-shaped groove at an angle of 0°-90° via the first rotating shaft. The rotating mechanism drives the bending mechanism to roll along the side wall of the mounting plate with the second rotating shaft as its center. The inner wall of the U-shaped clamp tube to be processed is fitted onto one side wall of the mounting plate, securing the U-shaped clamp tube between the side wall of the mounting plate and the groove of the bending mechanism. The mechanism rotates around the second pivot, driving the bending mechanism to roll along the side wall of the mounting plate. As the rotation angle of the rotating mechanism changes, the bending mechanism rolls from one side of the mounting plate to the adjacent side. At the same time, the first pivot limits the rotation of the rotating mechanism within the arc groove, allowing the rotating mechanism to rotate between 0° and 90°, thereby bending the U-shaped clamp tube between the side wall of the mounting plate and the groove. This effectively ensures that the bending mechanism can bend the U-shaped clamp tube according to the preset rotation angle range of the rotating mechanism during the rolling process, avoiding inaccurate bending angles caused by excessive or insufficient rotation angles, and greatly improving the bending accuracy and ease of operation of the U-shaped clamp tube.
[0022] As a further embodiment of this utility model, a handle is provided on the side of the upper support plate and the lower support plate away from the mounting plate.
[0023] By installing handles on the upper and lower support plates on the side away from the mounting plate, operators can more easily control the rotation of the rotating mechanism, ensuring that operators' hands do not feel excessively fatigued during long-term operation, effectively improving operating comfort and reducing labor intensity.
[0024] As a further embodiment of this utility model: the bending mechanism is a roller, which is rotatably disposed in the cavity between the upper support plate and the lower support plate, and the groove is disposed around the outer wall of the roller.
[0025] Because the bending mechanism is a roller, the roller is rotated and set in the cavity between the upper and lower support plates. The groove is located around the outer wall of the roller. The rolling characteristics of the roller make the friction between the roller and the U-shaped clamp tube rolling friction when it rolls along the side wall of the mounting plate to bend the U-shaped clamp tube. Compared with sliding friction, it can effectively reduce the scratching and wear on the surface of the U-shaped clamp tube, ensure the smoothness and integrity of the U-shaped clamp tube surface, and thus improve the processing quality of the product.
[0026] As a further embodiment of this utility model: the mounting plate is provided with a plurality of connection holes, and the mounting plate is bolted to the workbench through the plurality of connection holes.
[0027] Because the mounting plate has several connection holes, it is bolted to the workbench through these holes. The workbench provides effective support for the mounting plate, ensuring its structural stability and preventing it from loosening or sliding during U-shaped clamp pipe bending operations. This ensures the reliability and efficiency of the U-shaped clamp pipe bending operation.
[0028] As a further improvement of this utility model, the connection between adjacent sides of the mounting plate is provided with an arc-shaped edge.
[0029] To facilitate the bending mechanism's rolling from one side of the mounting plate to the adjacent side, an arc-shaped edge is provided at the connection between the adjacent sides of the mounting plate. This provides a smooth transition area for the bending mechanism, allowing it to change its rolling direction naturally and smoothly along the arc-shaped edge, avoiding the jamming phenomenon caused by right-angle transitions. At the same time, it allows the U-shaped clamp pipe to gradually change direction during bending, dispersing the stress distribution at the corner and making the stress act more evenly on the pipe. This greatly reduces the possibility of breakage at the corner of the U-shaped clamp pipe, ensuring the integrity and strength of the product. Attached Figure Description

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0042] like Figure 1-3The present invention, as shown in this embodiment, provides a bending fixture for U-shaped clamp pipes, comprising: a workpiece to be processed and a worktable, wherein a mounting plate 1 is provided on one side of the top of the worktable; a rotating mechanism 2 is movably provided on one side of the mounting plate 1, and a bending mechanism 3 is rotatably provided in the middle of the rotating mechanism 2, wherein a groove 31 is provided along the outer circumference of the bending mechanism 3, the width of the groove 31 being adapted to the thickness of the side wall of the mounting plate 1; the rotating mechanism 2 can drive the bending mechanism 3 to rotate along the side wall of the mounting plate 1; the workpiece to be processed is engaged between the side wall of the mounting plate 1 and the groove 31.
[0043] In use, the inner wall of the U-shaped clamp tube to be processed is fitted onto one side wall of the mounting plate 1, and the U-shaped clamp tube is engaged between the side wall of the mounting plate 1 and the groove 31 of the bending mechanism 3. At this time, the rotating mechanism 2 is rotated, and the bending mechanism 3 rolls along the side wall of the mounting plate 1 under the drive of the rotating mechanism. As the rotation angle of the rotating mechanism 2 changes, the bending mechanism 3 rolls from one side of the mounting plate 1 to the adjacent side, thereby bending the U-shaped clamp tube between the side wall of the mounting plate 1 and the groove 31.
[0044] Specifically, the U-shaped clamp pipe using a bending fixture can effectively engage the U-shaped clamp pipe between the side wall of the mounting plate 1 and the groove 31 of the bending mechanism 3 for positioning and limiting. Under the rotation of the rotating mechanism 2, a rolling bending method is used to drive the bending mechanism 3 to roll along the side wall of the mounting plate 1. As the rotation angle of the rotating mechanism 2 changes, the bending mechanism 3 rolls from one side of the mounting plate 1 to the adjacent side, thereby bending the U-shaped clamp pipe between the side wall of the mounting plate 1 and the groove 31. This effectively prevents direct squeezing interference to the side wall of the U-shaped clamp pipe by the traditional bending method, reducing pipe damage. This reduces the probability of bending the U-shaped clamp tube without requiring complex adjustments or additional fixing steps, lowering the operational difficulty and improving the flexibility and convenience of bending the U-shaped clamp tube, ensuring the bending quality and efficiency of the U-shaped clamp tube. Simultaneously, the bending angle of the U-shaped clamp tube can be determined based on the angle between two adjacent sidewalls of the mounting plate 1, making the bending angle range of the U-shaped clamp tube wider. Furthermore, after one end of the U-shaped clamp tube is bent, it can be removed, and the other end of the U-shaped clamp tube can be bent again to achieve the U-shape bending operation, meeting different usage requirements of the U-shaped clamp tube.
[0045] According to an embodiment of the present invention, the rotating mechanism 2 includes a long plate 21, which is provided with an upper support plate 211 and a lower support plate 212. The mounting plate 1 is disposed in the cavity between the upper support plate 211 and the lower support plate 212. A first rotating shaft 22 and a second rotating shaft 23 are provided through the upper support plate 211, the mounting plate 1 and the lower support plate 212. An arc-shaped groove 11 is provided on the mounting plate 1. The first rotating shaft 22 is disposed through the arc-shaped groove 11 and rotates along the arc-shaped groove 11. The rotating mechanism 2 rotates along the arc-shaped groove 11 by the first rotating shaft 22 at an angle of 0°-90°. The rotating mechanism 2 drives the bending mechanism 3 to roll along the side wall of the mounting plate 1 with the second rotating shaft 23 as the center.
[0046] Specifically, the rotating mechanism 2 includes a long plate 21, which is provided with an upper support plate 211 and a lower support plate 212. The mounting plate 1 is disposed in the cavity between the upper support plate 211 and the lower support plate 212. A first rotating shaft 22 and a second rotating shaft 23 are provided through the upper support plate 211, the mounting plate 1, and the lower support plate 212. An arc-shaped groove 11 is provided on the mounting plate 1. The first rotating shaft 22 is disposed through the arc-shaped groove 11 and rotates along the arc-shaped groove 11. The rotating mechanism 2 rotates along the arc-shaped groove 11 by a limited angle of 0°-90° through the first rotating shaft 22. The rotating mechanism 2 drives the bending mechanism 3 to roll along the side wall of the mounting plate 1 with the second rotating shaft 23 as the center. The inner wall of the U-shaped clamp tube to be processed is sleeved on one side wall of the mounting plate 1, and the U-shaped clamp tube is clamped onto the mounting plate 1. Between the side wall and the groove 31 of the bending mechanism 3, the rotating mechanism 2 rotates around the second rotating shaft 23 as the center, driving the bending mechanism 3 to roll along the side wall of the mounting plate 1. As the rotation angle of the rotating mechanism 3 changes, the bending mechanism 3 rolls from one side of the mounting plate 1 to the adjacent side. At the same time, the first rotating shaft 22 limits the rotation of the rotating mechanism 2 in the arc groove 11, so that the rotating mechanism 2 can rotate between 0° and 90°, thereby bending the U-shaped clamp tube between the side wall of the mounting plate 1 and the groove 31. This effectively ensures that the bending mechanism 3 can bend the U-shaped clamp tube according to the preset rotation angle range of the rotating mechanism 2 during the rolling process, avoiding inaccurate bending angles caused by excessive or insufficient rotation angles, and greatly improving the bending accuracy and ease of operation of the U-shaped clamp tube.
[0047] Furthermore, handles 24 are provided on the side of the upper support plate 211 and the lower support plate 212 away from the mounting plate 1.
[0048] Specifically, by providing handles 24 on the side of the upper support plate 211 and the lower support plate 212 away from the mounting plate 1, the operator can more easily control the rotation of the rotating mechanism 2, ensuring that the operator's hands will not feel excessive fatigue during long-term operation, effectively improving operating comfort and reducing labor intensity.
[0049] According to embodiments of the present invention, such as Figure 2As shown, the bending mechanism 3 is a roller, which is rotatably disposed in the cavity between the upper support plate 211 and the lower support plate 212, and the groove 31 is disposed around the outer wall of the roller.
[0050] Specifically, since the bending mechanism 3 is a roller, the roller is rotatably set in the cavity between the upper support plate 211 and the lower support plate 212. The groove 31 is arranged around the outer wall of the roller. The rolling characteristics of the roller make the friction between the roller and the U-shaped clamp tube rolling friction when it rolls along the side wall of the mounting plate 1 to bend the U-shaped clamp tube. Compared with sliding friction, it can effectively reduce the scratching and wear on the surface of the U-shaped clamp tube, ensure the smoothness and integrity of the U-shaped clamp tube surface, and thus improve the processing quality of the product.
[0051] It should also be noted that the mounting plate 1 is provided with several connection holes 12, and the mounting plate 1 is bolted to the workbench through several connection holes 12.
[0052] Specifically, since the mounting plate 1 is provided with several connection holes 12, the mounting plate 1 is bolted to the workbench through several connection holes 12. The workbench can provide effective support for the mounting plate 1, which can effectively ensure the structural stability of the mounting plate 1 and prevent the mounting plate 1 from loosening or sliding when the U-shaped clamp tube is bent, thus ensuring the reliability and efficiency of the U-shaped clamp tube bending operation.
[0053] Furthermore, the connection between adjacent sides of the mounting plate 1 is provided with an arc-shaped edge 13.
[0054] Specifically, to facilitate the bending mechanism 3 rolling from one side of the mounting plate 1 to the adjacent side of the mounting plate 1, an arc-shaped edge 13 is provided at the connection between the adjacent sides of the mounting plate 1, providing a smooth transition area for the bending mechanism 3. This allows the bending mechanism 3 to change its rolling direction naturally and smoothly along the arc-shaped edge 13, avoiding the jamming phenomenon caused by right-angle transition. At the same time, it enables the U-shaped clamp pipe to gradually change direction when bending, dispersing the stress distribution at the corner and making the stress act more evenly on the pipe, greatly reducing the possibility of breakage at the corner of the U-shaped clamp pipe, and ensuring the integrity and strength of the product.
[0055] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
