Description

Technical Field

[0001] This utility model relates to the field of pipe straightening technology, specifically to a pipe straightening device. Background Technology

[0002] Currently, when installing some equipment on-site, it may be necessary to straighten coiled thin-walled pipes. For example, when installing an air conditioner, it is necessary to straighten the thin-walled copper pipes (which are coiled at the factory for easy packaging and transportation) that will be used. These thin-walled copper pipes are used to connect the indoor and outdoor units and serve as the air conditioning refrigerant circulation pipes.

[0003] In actual installation, the straightening method for this type of pipe is generally to use a rigid rod-like structure (such as a wooden stick, iron pipe, etc.) as a reference, pull out the coiled thin-walled copper pipe and insert the rod-like structure into the thin-walled copper pipe to be straightened, and then use the rod-like structure to straighten the pulled-out thin-walled copper pipe.

[0004] While this straightening method is convenient and quick, it has the following problems: it can easily damage the inner wall of the thin-walled copper tube, affecting its normal use; and if the radial dimension difference between the rod-shaped structure and the thin-walled copper tube is large, the straightening degree of the thin-walled copper tube may be insufficient, making it inconvenient to use. Furthermore, this straightening method is not easily adapted to thin-walled copper tubes with different radial dimensions, and it is often necessary to carry multiple rod-shaped structures with different radial dimensions as spares, which is very inconvenient. Utility Model Content

[0005] In order to solve the technical problems in related technologies, this utility model provides a pipe straightening device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Pipe straightening equipment, including:

[0008] The bracket is used for mounting on the workbench.

[0009] The working cylinder is mounted on the support, and a through cylindrical straightening cavity is formed inside the working cylinder, which extends horizontally.

[0010] A straightening assembly is disposed within a straightening cavity. The straightening assembly includes several straightening components and several mounting blocks. The mounting blocks are spaced apart circumferentially around the straightening cavity to collectively enclose a cylindrical working cavity for pipes to pass through. A straightening component is disposed between every two adjacent mounting blocks. The straightening component includes a mounting strip and several straightening wheels. The mounting strip is disposed axially along the straightening cavity. The several straightening wheels are rotatably mounted on the mounting strip. First connecting members are disposed at both ends of the mounting strip. Several second connecting members corresponding to the first connecting members are disposed at both ends of the mounting blocks. The several second connecting members are spaced apart in a direction perpendicular to the axial direction of the straightening cavity. The first connecting members and the second connecting members are detachably connected so that the position of the straightening wheels can be adjusted radially along the working cavity.

[0011] Optionally, the mounting block is formed into a U-shaped structure. The mounting block includes a first block and a second block arranged opposite to each other, and a third block connected between the first block and the second block. The third block is formed into an arc-shaped plate structure. The third blocks of several mounting blocks together enclose a cylindrical working cavity. The second connector is disposed on the first block and the second block.

[0012] Optionally, an installation cavity communicating with the straightening cavity is formed inside the working cylinder. The installation cavity is used to accommodate the first block, the second block, and the straightening component. The first block, the second block, and the third block are respectively fixedly installed inside the straightening cavity.

[0013] Optionally, the first connector is configured as a bolt, and the second connector is configured as a bolt hole.

[0014] Optionally, the mounting strip includes a strip body and two adjusting strips, which are respectively disposed at both ends of the strip body. Several straightening wheels are rotatably connected to the strip body, and a first connecting member is disposed on the adjusting strip.

[0015] Optionally, in the vertical direction, the projection of the adjusting bar falls within the projection of the working cylinder.

[0016] Optionally, the straightening wheel includes a wheel body and a rubber ring fitted around the wheel body.

[0017] Optionally, at least four straightening components should be provided.

[0018] Optionally, along the axial direction of the straightening cavity, the radial dimensions of the several straightening wheels located at the front gradually increase, and the radial dimensions of at least two straightening wheels located at the rear are the same.

[0019] Optionally, the bracket includes an interconnected mounting plate and a mounting rod, with one end of the mounting rod away from the mounting plate connected to the working cylinder, and a plurality of mounting holes formed on the mounting plate.

[0020] Beneficial effects:

[0021] 1. The above technical solution effectively avoids damage to the inner wall of the thin-walled pipe. Specifically, when the pipe passes through the equipment, the straightening wheel contacts the outer wall of the thin-walled pipe and undergoes rolling friction, rather than the sliding friction between the rod and the inner wall of the pipe as in the prior art. The frictional force of rolling friction is much smaller than that of sliding friction. In this way, the risk of scratching or scraping the pipe (whether the inner or outer wall) during the straightening process can be effectively avoided, ensuring the integrity of the pipe and the reliability of its subsequent use.

[0022] Secondly, it can effectively improve the straightening accuracy and effect. Specifically, the working cavity formed by multiple mounting blocks is a regular and stable cylindrical space, which can provide a precise geometric reference for the straightening process. When the pipe passes through this working cavity, its curved part will be forcibly constrained within this reference shape, thereby ensuring the straightness after straightening. At the same time, multiple straightening wheels distributed along the axial direction constitute a continuous straightening area. When the pipe passes through, it will undergo a multi-point straightening process, further improving the straightening accuracy and effect to achieve the desired straightening effect.

[0023] Third, it can effectively adapt to the straightening needs of pipes with different radial dimensions. Specifically, the setting of the first and second connectors allows the diameter of the straightening space enclosed by the entire straightening assembly to be adjustable. By selecting to install the straightening component on the second connector at different radial positions, the circumference formed by all the straightening wheels can be changed. In this way, it can be adapted to pipes of different diameters through simple adjustments, thereby effectively addressing the pain point in the background technology that "it is not easy to adapt to thin-walled copper pipes with different radial dimensions, and it is often necessary to carry multiple radial dimensions of rod-shaped structures for backup, which is very inconvenient," eliminating the trouble of carrying multiple tools, and improving work efficiency and equipment versatility.

[0024] Fourth, this utility model has the advantages of stable structure and ease of assembly and maintenance. Specifically, the bracket provides basic support; the working cylinder provides a sturdy and reliable mounting platform and guide channel; the straightening component, as the core functional module, is stably set in the straightening cavity through the mounting block. Meanwhile, the straightening component and the mounting block are detachably connected. In this way, the entire device has sufficient rigidity, preventing shaking during the straightening process and ensuring straightening accuracy. Furthermore, the detachable connection makes the installation, disassembly, and replacement of the straightening component, as well as the radial position adjustment to adapt to the pipe diameter, very convenient, facilitating maintenance and adjustment.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] 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.

[0037] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 6 As shown, this embodiment provides a pipe straightening device 100, including a support 1, a working cylinder 2, and a straightening assembly 3. The support 1 is mounted on a workbench. The working cylinder 2 is mounted on the support 1, and a through cylindrical straightening cavity 21 is formed within the working cylinder 2, extending horizontally. The straightening assembly 3 is disposed within the straightening cavity 21. The straightening assembly 3 includes several straightening components 31 and several mounting blocks 32. The mounting blocks 32 are spaced apart circumferentially around the straightening cavity 21 to enclose a cylindrical working cavity for pipes to pass through. A straightening component 31 is disposed between every two adjacent mounting blocks 32. The straightening component 31 includes a mounting strip 311 and several straightening wheels 312. The mounting strip 311 is disposed axially around the straightening cavity 21. Several straightening wheels 312 are rotatably mounted on the mounting strip 311. First connecting members 313 are disposed at both ends of the mounting strip 311. Several second connecting members 321 corresponding to the first connecting members 313 are disposed at both ends of the mounting blocks 32. Several second connecting members 321 are spaced apart in a direction perpendicular to the axial direction of the straightening cavity 21. The first connecting members 313 and the second connecting members 321 are detachably connected so that the position of the straightening wheels 312 can be adjusted radially along the working cavity.

[0039] The above technical solution effectively avoids damage to the inner wall of the thin-walled pipe. Specifically, when the pipe passes through the equipment, the straightening wheel 312 contacts the outer wall of the thin-walled pipe and undergoes rolling friction, rather than the sliding friction between the rod and the inner wall of the pipe as in the prior art. The frictional force of rolling friction is much smaller than that of sliding friction. In this way, the risk of scratching or scraping the pipe (whether the inner or outer wall) during the straightening process can be effectively avoided, ensuring the integrity of the pipe and the reliability of its subsequent use.

[0040] Secondly, it can effectively improve the straightening accuracy and straightening effect. Specifically, the working cavity formed by the multiple mounting blocks 32 is a regular and stable cylindrical space, which can provide a precise geometric reference for the straightening process. When the pipe passes through this working cavity, its curved part will be forcibly constrained within this reference shape, thereby ensuring the straightness after straightening. At the same time, the multiple straightening wheels 312 distributed along the axial direction constitute a continuous straightening area. When the pipe passes through, it will undergo a multi-point straightening process, further improving the straightening accuracy and straightening effect to achieve the desired straightening effect.

[0041] Third, it can effectively adapt to the straightening requirements of pipes with different radial dimensions. Specifically, the arrangement of the first connector 313 and the second connector 321 allows the diameter of the straightening space enclosed by the entire straightening assembly 3 to be adjustable. By selecting to install the straightening component 31 on the second connector 321 at different radial positions, the circumference formed by all the straightening wheels 312 can be changed. In this way, it can be adapted to pipes of different diameters through simple adjustments, thereby effectively addressing the pain point in the background technology that "it is not easy to adapt to thin-walled copper pipes with different radial dimensions, and it is often necessary to carry multiple radial dimensions of rod-shaped structures for backup, which is very inconvenient," eliminating the trouble of carrying multiple tools, and improving work efficiency and equipment versatility.

[0042] Fourth, this utility model has the advantages of stable structure and easy assembly and maintenance. Specifically, the bracket 1 provides basic support; the working cylinder 2 provides a sturdy and reliable installation platform and guide channel; the straightening component 3, as the core functional module, is stably set in the straightening cavity 21 through the mounting block 32. Meanwhile, the straightening component 31 and the mounting block 32 are detachably connected. In this way, the entire device has sufficient rigidity, preventing shaking during the straightening process and ensuring straightening accuracy. At the same time, the detachable connection makes the installation, disassembly, and replacement of the straightening component 31, as well as the radial position adjustment to adapt to the pipe diameter, very convenient, facilitating maintenance and adjustment.

[0043] In one embodiment of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the mounting block 32 of this utility model can be formed into a U-shaped structure. The mounting block 32 includes a first block 322 and a second block 323 arranged opposite to each other, and a third block 324 connected between the first block 322 and the second block 323. The third block 324 is formed into an arc-shaped plate structure. The third blocks 324 of several mounting blocks 32 together enclose a cylindrical working cavity. The second connector 321 is disposed on the first block 322 and the second block 323.

[0044] Thus, by configuring the mounting block 32 in this way, firstly, a stable and accurate straightening reference surface can be provided. Specifically, the inner arc surface of the third block 324 directly forms the cavity wall of the straightening working chamber. This inner arc surface can provide a high-precision geometric reference for pipe straightening, providing a basis for the accurate installation of the straightening wheel 312, thereby effectively improving the accuracy and consistency of straightening.

[0045] Secondly, it optimizes the stress structure of the mounting block 32, enhancing connection rigidity and stability. Specifically, when the straightening component 31 is installed on the second connecting component 321 via the first connecting component 313, the radial force of the pipe on the straightening wheel 312 is transmitted through the mounting strip 311 to the first block 322 and the second block 323 (another mounting block 32) of the mounting block 32. Furthermore, the U-shaped mounting block 32 is a closed frame, with structural strength far superior to a single cantilever or support plate structure, effectively resisting and dispersing the radial force generated during straightening, preventing deformation of the mounting block 32 itself. Simultaneously, the two ends of the straightening component 31 are fixed to the first block 322 and the second block 323 (another mounting block 32) respectively, forming a two-point fixation. This effectively enhances the stability of the straightening component 31 after installation, effectively preventing it from swaying or twisting around the connection point under stress, thereby ensuring the accuracy of the straightening wheel 312's position and operational reliability.

[0046] In one embodiment of this utility model, such as Figure 3 As shown, the working cylinder 2 of this utility model can form an installation cavity 22 that communicates with the straightening cavity 21. The installation cavity 22 is used to accommodate the first block 322, the second block 323 and the straightening component 31. The first block 322, the second block 323 and the third block 324 are respectively fixedly installed in the straightening cavity 21.

[0047] In this embodiment, the mounting block 32 is no longer an independent module suspended in the straightening cavity 21. Each part of it is fixed to the wall of the robust working cylinder 2. This provides an extremely solid mounting foundation for the entire straightening assembly 3. When the straightening wheel 312 applies a straightening force to the pipe, the reaction force is directly and efficiently transmitted to the working cylinder 2 and even the entire support 1 through the mounting block 32. This effectively reduces local deformation and vibration, ensuring a smooth and precise straightening process. Simultaneously, this design allows for a very compact overall structure with no exposed connecting structures. Most functional units are integrated into a robust working cylinder 2, effectively reducing the overall size and footprint of the equipment, making it easier to install, carry, and store on-site.

[0048] In one embodiment of this utility model, the first connecting member 313 can be configured as a bolt, and the second connecting member 321 can be configured as a bolt hole. In this embodiment, the detachable connection is achieved through the form of a bolt and a bolt hole, which not only effectively ensures a stable and reliable connection, but also has good vibration and impact resistance, and also has the advantages of simple structure and easy processing.

[0049] In one embodiment of this utility model, such as Figure 4 and Figure 6 As shown, the mounting strip 311 of this utility model may include a strip body 3111 and two adjusting strips 3112. The two adjusting strips 3112 are respectively disposed at both ends of the strip body 3111. Several straightening wheels 312 are rotatably connected to the strip body 3111. The first connecting member 313 is disposed on the adjusting strips 3112.

[0050] In this way, the adjusting bar 3112 serves as the structure for the first connecting member 313, which not only facilitates the setting or installation of the first connecting member 313 with sufficient strength, but also serves as the operating basis for adjusting the straightening member 31, allowing the operator to hold it to change its spatial position and providing convenience for operation.

[0051] In one embodiment of this invention, the projection of the adjusting bar 3112 falls within the projection of the working cylinder 2 in the vertical direction. This structural design ensures that the adjusting bar 3112 (and the first connecting member 313 disposed thereon) does not exceed the maximum outer contour of the working cylinder 2 in the vertical direction, effectively preventing the adjusting bar 3112 from protruding from the working cylinder 2. In busy or confined construction sites, this effectively reduces the risk of operators getting their clothing caught on protruding bolt heads or the adjusting bar 3112 and sustaining abrasions when passing through or carrying equipment. It also means that the adjusting mechanism will not be damaged by accidental collisions (such as damage to the first adjusting member) during equipment storage, transportation, or on-site movement.

[0052] In one embodiment of this utility model, such as Figure 6 As shown, the straightening wheel 312 of this utility model may include a wheel body 3121 and a rubber ring 3122 sleeved on the outside of the wheel body 3121. With this configuration, the straightening wheel 312 not only forms a protective buffer layer between the wheel body 3121 and the thin-walled pipe at the contact point, preventing potential problems such as indentations, scratches, or stringing, but also provides cushioning (reducing noise and mitigating impact). Furthermore, the rubber ring 3122 increases the contact area (the rubber ring 3122 deforms and adheres to the outer wall of the thin-walled pipe), enhancing friction and reducing the possibility of slippage, thereby improving the efficiency of the straightening operation.

[0053] In one embodiment of this invention, at least four straightening components 31 are provided. In this way, on one hand, at least four straightening components 31 can overcome unstable structures (for example, taking three straightening components 31 as an example, in the straightening process of thin-walled pipes, three straightening components 31 correspond to three-point support, which may lead to pipe deflection or jamming between two straightening components 31), and can effectively form a more stable and uniform envelope and constraint on the thin-walled pipe in the circumferential direction, thereby effectively ensuring the smoothness and reliability of straightening.

[0054] On the other hand, this multi-point (at least four-point) continuous constraint can effectively prevent thin-walled pipes from experiencing localized indentations, buckling, or circumferential torsion due to uneven stress, ensuring the smooth progress of the straightening process and the shape integrity of the straightened pipe. Simultaneously, it can distribute the radial force during the straightening process across more stress points, resulting in smaller loads on each connection point and structural component, more rational stress distribution throughout the system, reduced risk of localized overload, and improved equipment capacity and durability when handling harder or more curved pipes.

[0055] In one embodiment of the present invention, along the axial direction of the straightening cavity 21, the radial dimensions of the several straightening wheels 312 located at the front gradually increase, and the radial dimensions of at least two straightening wheels 312 located at the rear are the same.

[0056] Thus, through this implementation method, firstly, a gradual, phased straightening process can be achieved. Specifically, by using a plurality of straightening rollers 312 arranged in this way, the straightening process can be divided into two stages along the axial direction of the pipe's advance: a "preliminary straightening stage" consisting of straightening rollers 312 with gradually increasing radial dimensions, and a "final shaping stage" consisting of straightening rollers 312 with the same radial dimensions. In the preliminary straightening stage, the pipe first passes through the smaller straightening rollers 312. These smaller rollers can more easily "bite" into the bent pipe and begin to apply straightening force. As the pipe advances, the size of the subsequent straightening rollers 312 gradually increases, and the straightening force and constraint force on the pipe also gradually increase. This gradual approach avoids using the largest rollers to perform a relatively "violent" straightening of the bent pipe from the beginning, thereby greatly reducing the risk of local wrinkles, indentations, or tears in the pipe, which is especially crucial for thin-walled pipes. In the final shaping stage, after passing through the straightening section, the main bends of the pipe have been eliminated. At least two straightening rollers 312 of the same size at the rear form a precise and stable calibration channel. Its function is to perform final fine straightening and shaping of the pipe, eliminate the slight stress deformation that may have occurred in the previous stage, and ensure that the pipe reaches the highest straightness accuracy when it is discharged.

[0057] Secondly, this gradually tapering structural design at the front end is well-suited for straightening severely bent pipes. Severely bent pipes may not be able to be directly placed into a fixed working chamber whose size matches the target pipe diameter. The gradually enlarging guide wheel design, like a trumpet-shaped inlet, can better guide and accept the bent pipe head and gradually begin the straightening process, thus expanding the processing capacity of the equipment.

[0058] Third, the at least two straightening rollers 312 with the same radial dimension set at the rear serve as a shaping section, which can ensure that each pipe undergoes a stable calibration process with exactly the same dimensions in the final stage of the straightening process. This calibration process can eliminate the final dimensional deviation that may be caused by minor differences or wear of the straightening rollers 312 in the front section, ensuring that all processed pipes have consistent high quality.

[0059] In one embodiment of this utility model, such as Figure 1 As shown, the bracket 1 of this utility model may include an interconnected mounting plate 11 and a mounting rod 12. The end of the mounting rod 12 away from the mounting plate 11 is connected to the working cylinder 2. A plurality of mounting holes 111 are formed on the mounting plate 11.

[0060] In this embodiment, firstly, the mounting plate 11 itself can serve as a mounting base, providing a stable placement effect on a relatively flat working surface. Secondly, the mounting rod 12 can "lift" the working cylinder 2 to a suitable height, facilitating pipe threading and pulling operations for the operator. Furthermore, the mounting hole 111 can serve as a structure to further enhance the installation strength, allowing the entire device to be flexibly installed on different working surfaces, adapting to complex on-site environments.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
