Description

Technical Field

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

[0002] In the field of copper tube processing, the straightening process is a core step in ensuring the accuracy of subsequent assembly, welding and other processes. Especially for industries such as refrigeration, sanitary ware and electronics, which have strict requirements for the straightness of copper tubes, the straightening quality directly determines the performance of the end product.

[0003] Currently, mainstream copper tube hydraulic straightening devices in the industry have significant technical shortcomings: First, the loading and unloading processes are disconnected from the cleaning process. Most devices require manual handling to first move the copper tubes to a separate cleaning device to remove surface dust, oil, and metal debris before transferring them to the straightening device. This not only increases the labor intensity of operators but also easily leads to secondary impacts and deformation of the copper tubes due to repeated handling. In addition, the extra cleaning process prolongs the processing cycle and reduces production efficiency. Second, the calibration structure lacks flexibility. Existing devices mostly use fixed limiting components. For copper tubes of different diameters, special limiting components need to be disassembled and replaced. The adjustment process is cumbersome and time-consuming, with poor adaptability, making it difficult to meet the batch processing needs of copper tubes of various specifications. Third, the positioning accuracy is low when loading and unloading manually. Operators place the copper tubes on the straightening table based solely on experience, which easily leads to copper tube misalignment, causing deviation of the straightener's force point, resulting in local over-straightening or surface damage of the copper tubes. This results in a low product qualification rate and increases raw material waste and rework costs. Utility Model Content

[0004] The problem this invention aims to solve is to provide a hydraulic straightening device for copper tubes. This invention integrates the cleaning components next to the calibration mechanism. Utilizing the movement trajectory of the copper tube during manual loading and unloading, the copper tube passes through the first and second nylon brushes twice during the loading and unloading processes. With the help of double-layered bristles adapted to copper tubes of different diameters, it achieves both preliminary cleaning and fine cleaning effects. There is no need to set up additional cleaning procedures and drive structures. This not only significantly shortens the processing cycle but also avoids secondary damage to the copper tube caused by repeated handling, significantly improving the surface cleanliness of the copper tube and meeting the surface quality requirements of high-precision processing.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: A copper tube hydraulic straightening device includes a first mounting base, a first placement platform, straighteners, a hydraulic cylinder, a second placement platform, and a control end. The first placement platform is installed inside the first mounting base, and the second placement platform is slidably installed inside the first mounting base. The first and second placement platforms are used in conjunction. A plurality of straighteners are installed on the top of the first and second placement platforms. The hydraulic cylinder is fixed to the side wall of the first mounting base by bolts, and the telescopic end of the hydraulic cylinder is connected to the side wall of the second placement platform. The control end is installed on the side wall of the first mounting base and is electrically connected to the hydraulic cylinder. The device also includes a calibration mechanism and a cleaning component. The calibration mechanism is used to calibrate the position of the copper tube, and the cleaning component is used to clean the surface of the copper tube.

[0006] More preferably, the calibration mechanism and the cleaning components are symmetrically arranged.

[0007] More preferably, the calibration mechanism includes a second mounting base, a bidirectional adjusting rod, a guide rod, a first pressure roller, a second pressure roller, a connector, a connecting seat, a spring, and a limiting roller. The second mounting base is mounted on top of the first mounting base. The bidirectional adjusting screw is rotatably mounted on top of the second mounting base. The guide rod is fixedly connected to the top of the second mounting base. The symmetrically arranged first pressure rollers are slidably connected to the guide rod. Each first pressure roller is threadedly connected to the bidirectional adjusting screw and slides on the second mounting base. The symmetrically arranged connectors are fixedly connected to the upper first pressure rollers. The symmetrically arranged connecting seats are slidably connected to the corresponding connectors. The spring connects the connecting seat and the connector. The second pressure roller is mounted between the symmetrically arranged connecting seats. Both the first and second mounting bases have several placement holes, which are interconnected. The limiting roller is inserted into the placement holes of the second and first mounting bases.

[0008] More preferably, the limiting roller near the second placement platform cannot be adjusted, while the other limiting roller can be adjusted in position according to the size of the copper tube.

[0009] More preferably, the cleaning assembly includes a first nylon brush, a second nylon brush, and fasteners, with both the first and second nylon brushes mounted on a second mounting base via fasteners.

[0010] More preferably, the bristles of the second nylon brush are shorter than those of the first nylon brush, making it easier to adapt to copper tubes of different sizes.

[0011] Compared with the prior art, the advantages of this utility model are: This utility model integrates the cleaning component next to the calibration mechanism. By utilizing the movement trajectory of the copper tube during manual loading and unloading, the copper tube passes through the first nylon brush and the second nylon brush twice during the loading and unloading processes. With the help of double-layer bristles to adapt to copper tubes of different diameters, it achieves the dual effect of preliminary cleaning and fine cleaning. There is no need to set up additional cleaning processes and drive structures. This not only greatly shortens the processing cycle, but also avoids secondary damage to the copper tube caused by repeated handling, and significantly improves the surface cleanliness of the copper tube, meeting the surface quality requirements of high-precision processing.

[0012] The calibration mechanism drives the first pressure roller to slide along the guide rod via a bidirectional adjustment rod, and uses multiple sets of placement holes to adjust the position of the limit roller. It can adapt to copper tubes of different specifications without disassembling or replacing parts, greatly shortening the adjustment time. At the same time, the spring between the connector and the connecting seat provides elastic buffering to avoid hard contact between the limit component and the copper tube during calibration, effectively reducing the surface scratch rate. Combined with the bidirectional positioning of the limit roller and the pressure roller, the positioning error during manual loading and unloading is controlled to a very small range, significantly improving the straightening qualification rate and reducing raw material loss and rework costs.

[0013] The device integrates calibration, cleaning, and straightening functions onto the first mounting base. The compact layout of each component significantly reduces the floor space compared to traditional split-type equipment. The cleaning component is mounted on the second mounting base with fasteners, facilitating the replacement and maintenance of the nylon brush later. The electrical connection between the hydraulic cylinder and the control end enables automated control of the straightening process, reducing manual intervention and simplifying operation. Meanwhile, the symmetrically arranged calibration mechanism and cleaning component ensure balanced force during device operation, improving overall stability, significantly reducing the failure rate, and extending the equipment's service life.

[0024] Example: As shown in the attached figures, a copper tube hydraulic straightening device includes a first mounting base 1, a first placement platform 2, a straightener 3, a hydraulic cylinder 4, a second placement platform 5, and a control end 6. The first placement platform 2 is installed inside the first mounting base 1, and the second placement platform 5 is slidably installed inside the first mounting base 1. The first placement platform 2 and the second placement platform 5 are used together to place the copper tube to be straightened. Several straighteners 3 are installed on the top of the first placement platform 2 and the second placement platform 5. The straighteners 3 are used to straighten the copper tube. The hydraulic cylinder 4 is fixed to the side wall of the first mounting base 1 by bolts. The telescopic end of the hydraulic cylinder 4 is connected to the side wall of the second placement platform 5. The control end 6 is installed on the side wall of the first mounting base 1 and is electrically connected to the hydraulic cylinder 4. It also includes a calibration mechanism 7 and a cleaning component 8. The calibration mechanism 7 and the cleaning component 8 are symmetrically arranged. The calibration mechanism 7 is used to calibrate the position of the copper tube, and the cleaning component 8 is used to clean the surface of the copper tube.

[0025] In this embodiment, specifically, the calibration mechanism 7 includes a second mounting base 71, a bidirectional adjusting rod 72, a guide rod 73, a first pressure roller 74, a second pressure roller 75, a connector 76, a connecting seat 77, a spring 78, and a limiting roller 79. The second mounting base 71 is mounted on the top of the first mounting base 1. The bidirectional adjusting screw is rotatably mounted on the top of the second mounting base 71. The guide rod 73 is fixedly connected to the top of the second mounting base 71. The symmetrically arranged first pressure rollers 74 are slidably connected to the guide rod 73. Each of the first pressure rollers 74 is threadedly connected to the bidirectional adjusting screw. The first pressure rollers 74 slide on the second mounting base 71. The symmetrically arranged connectors 76 are fixedly connected to the upper first pressure rollers 74. The symmetrically arranged connecting seats 77 slide. The connecting rod is connected to the corresponding connecting piece 76. The spring 78 is connected between the connecting seat 77 and the connecting piece 76 to play a buffering role. The second pressure roller 75 is installed between the symmetrically arranged connecting seats 77. The lower first pressure roller 74 cooperates with the second pressure roller 75 to calibrate the vertical position of the copper tube. The first mounting seat 1 and the second mounting seat 71 are both provided with several placement holes. The placement holes on the first mounting seat 1 and the second mounting seat 71 are connected. The limiting roller 79 is inserted into the placement holes of the second mounting seat 71 and the first mounting seat 1. The limiting roller 79 near the second placement platform 5 cannot be adjusted. The other limiting roller 79 can be adjusted according to the size of the copper tube. The limiting roller 79 is used to calibrate the left and right sides of the copper tube.

[0026] Furthermore, the cleaning component 8 includes a first nylon brush 81, a second nylon brush 82, and a fastener 83. Both the first nylon brush 81 and the second nylon brush 82 are mounted on the second mounting base 71 by the fastener 83. The bristles of the second nylon brush 82 are shorter than those of the first nylon brush 81, making it easier to adapt to copper tubes of different sizes. The first nylon brush 81 and the second nylon brush 82 work together to clean impurities from the surface of the copper tube.

[0027] When using this copper tube hydraulic straightening device, first, according to the size and specifications of the copper tube to be straightened, rotate the bidirectional adjusting rod 72 to drive the symmetrically arranged first pressure roller 74 to slide along the guide rod 73. At the same time, adjust the movable limiting roller 79 according to the size of the copper tube, remove the limiting roller 79 from the placement hole that communicates with the first mounting base 1 and the second mounting base 71, select a suitable placement hole and reinsert it so that the distance between the two limiting rollers 79 matches the width of the copper tube, and complete the specification adaptation of the calibration mechanism 7.

[0028] The manual feeding stage then begins. The operator holds the copper tube to be straightened, aligns one end with the calibration mechanism 7, and slowly pushes it onto the top of the first placement table 2 and the second placement table 5. During the pushing process, the copper tube passes through the cleaning component 8. At this time, the first nylon brush 81 and the second nylon brush 82 in the cleaning component 8 are in close contact with the surface of the copper tube. Because the bristles of the second nylon brush 82 are shorter than those of the first nylon brush 81, it can adapt to copper tubes of different diameters. As the operator pushes the copper tube, the copper tube and the nylon brushes move relative to each other. The first nylon brush 81 first performs a preliminary cleaning of the surface of the copper tube, removing larger particles of impurities. The second nylon brush 82 then performs a fine cleaning of the surface of the copper tube, sweeping away residual dust, oil, etc., achieving synchronous cleaning during the feeding process and preventing impurities from entering the calibration and straightening area with the copper tube.

[0029] After the material is fed, the copper tube is placed stably on the top of the first placement platform 2 and the second placement platform 5, and is positioned between the two limiting rollers 79. The limiting rollers 79 limit and calibrate the left and right sides of the copper tube. The first pressure roller 74 and the second pressure roller 75 on the lower side cooperate to clamp the upper and lower surfaces of the copper tube. The spring 78 between the connector 76 and the connecting seat 77 provides elastic buffering to avoid excessive calibration pressure from damaging the surface of the copper tube and to ensure that the copper tube is in the center reference position required for straightening.

[0030] Upon receiving a signal, the hydraulic cylinder 4, activated by the control terminal 6, pushes the second placement platform 5 smoothly towards the first placement platform 2. Because the copper tube is clamped and limited by the first pressure roller 74 and the second pressure roller 75, the sliding of the second placement platform 5 does not cause the copper tube to move synchronously, and the copper tube remains in the central reference position. As the second placement platform 5 continues to advance, the straightener 3 at its top gradually approaches the straightener 3 at the top of the first placement platform 2. The straighteners 3 on both sides apply uniform hydraulic force to the bent portion of the copper tube in the fixed position, gradually correcting the deformation of the copper tube until the straightness of the copper tube meets the standard.

[0031] After straightening is completed, the hydraulic cylinder 4 is controlled by the control terminal 6 to reset the second placement platform 5, releasing the clamping state of the first pressure roller 74 and the second pressure roller 75 on the copper tube, and entering the manual unloading stage. The operator holds one end of the copper tube and slowly pulls it out from the first placement platform 2 and the second placement platform 5. During the pulling process, the copper tube passes through the cleaning component 8 again. The first nylon brush 81 and the second nylon brush 82 perform a secondary cleaning of any straightening debris that may remain on the surface of the straightened copper tube, ensuring that the surface of the unloaded copper tube is clean and no additional cleaning process is required.

[0032] Throughout the entire process, the placement hole provides a multi-position mounting base for the limiting roller 79. Combined with the bidirectional adjusting rod 72 to adjust the first pressure roller 74, the calibration mechanism 7 can accurately adapt to copper tubes of different specifications, reducing the positioning difficulty during manual loading. The cleaning component 8 utilizes the movement of the copper tube during manual loading and unloading to achieve two simultaneous cleaning operations, which simplifies the operation process and ensures the cleaning effect. All components work together to achieve integrated calibration, cleaning, and straightening operations, reducing manual intervention costs and preventing impurities from affecting the straightening accuracy or scratching the surface of the copper tube. This ensures that the straightness and surface cleanliness of the straightened copper tube meet the requirements of high-precision processing. The symmetrically arranged calibration mechanism 7 and cleaning component 8 further enhance the stability and consistency of the device operation.

This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
