Description

Technical Field

[0001] This invention belongs to the technical field of aluminum bronze tube straightening devices, specifically relating to a straightening mechanism for aluminum bronze tubes. Background Technology

[0002] Copper pipes are a very common material. Nowadays, copper pipes are divided into many types, among which aluminum bronze pipes have a very wide range of applications. After the aluminum bronze pipes are processed, they will usually bend under the action of external force. The bent aluminum bronze pipes will usually bend to one side. After the manufacturing is completed, the bent aluminum bronze pipes are usually straightened.

[0003] Existing aluminum bronze tube straightening mechanisms generally do not limit the internal cavity of the aluminum bronze tube during straightening. During the straightening process, the internal cavity of the aluminum bronze tube is easily deformed by the straightening compression, resulting in damage to the internal cavity of the tube. Most existing aluminum bronze tube straightening mechanisms can only straighten one aluminum bronze tube at a time, and the straightened aluminum bronze tube needs to be manually collected after straightening, which is quite troublesome and time-consuming. Therefore, we propose a new aluminum bronze tube straightening mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a straightening mechanism for aluminum bronze tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a straightening mechanism for aluminum bronze tubes, comprising a base platform, a feeding and shrinking mechanism provided at the middle of one end of the base platform, a connecting and fixing plate provided at one end of the feeding and shrinking mechanism, a straightening mechanism provided at the top of the connecting and fixing plate, and a protective auxiliary mechanism provided at one end of the top of the base platform.

[0007] Preferably, the protective auxiliary mechanism includes a rotating rod, with internal support rods provided at three nodes on the outer side of the rotating rod. A finished product conveying groove is fixedly connected to the other end of the base platform. Support columns are fixedly connected to both sides of the top of the base platform. A motor is provided at the top of one side of the support column. The output end of the motor is fixedly connected to one side of the rotating rod. Mounting grooves are fixedly connected at four nodes on the outer side of the internal support rod. A pulley is installed on the inner side of the mounting groove. An airbag block is fixedly connected to one end of the internal support rod.

[0008] Preferably, the feeding shrinking mechanism includes a shrinking rod, one end of which is fixedly connected to one end of a connecting fixing plate. A buffer spring is provided on the outer side of the shrinking rod. A protective box is fixedly connected to the top of one end of the connecting fixing plate. The top of the protective box is fixedly connected to the bottom of a limiting baffle. Track grooves are fixedly connected to both sides of the middle part of the top of the base platform.

[0009] Preferably, an auxiliary roller is fixedly connected to the bottom end of the connecting fixing plate, and an auxiliary roller groove is provided on the outer side of the auxiliary roller. A track block is fixedly connected to the bottom end of the protective box, and the track block is slidably connected to the track groove.

[0010] Preferably, there is one set of track grooves, one set of track blocks, one set of auxiliary rollers, and one set of auxiliary roller grooves.

[0011] Preferably, there are three sets of connecting limiting rods, three sets of roller connecting blocks, multiple sets of straightening rollers, and one set of connecting positioning plates.

[0012] Preferably, there are multiple sets of limiting rollers, multiple sets of limiting roller grooves, and a sliding limiting cavity is provided on the outer side of the bottom end of the connecting limiting rod.

[0013] Preferably, there are multiple sets of mounting slots and multiple sets of pulleys. The inner side of the airbag block is provided with a cavity, the middle part of the inner side of the internal support rod is provided with a cavity, the bottom end of the inner side of the mounting slot is fixedly connected with an air inlet, the air inlet is connected to the cavity on the inner side of the internal support rod, and one end of the inner side of the airbag block is fixedly connected with a through hole, the through hole is connected to the cavity on the inner side of the internal support rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: it facilitates the straightening of multiple aluminum bronze tubes at one time, which helps to improve the straightening efficiency, is more convenient during straightening, and helps to prevent the internal cavity of the aluminum bronze tube from being squeezed and deformed during straightening; it facilitates the discharge and feeding of the straightened aluminum bronze tubes, which is more convenient and labor-saving, and helps to save time in retrieving the straightened aluminum bronze tubes.

[0015] 1. Through the designed straightening mechanism, protective auxiliary mechanism, and feeding retraction mechanism, during use, the bent aluminum bronze tube is placed into the groove formed by the limiting baffle, so that one end of the aluminum bronze tube is attached to the surface of one end of the partition plate, and the other end of the aluminum bronze tube is attached to one end of the internal support rod. After placement, the retraction rod retracts, causing the connecting fixing plate to move inward, so that the track block fixedly connected to the bottom of the protective box slides steadily inward along the track groove, thereby causing the aluminum bronze tube placed at the top of the protective box to slowly slide onto the outer surface of the internal support rod. This causes the pulley installed in the mounting groove on the outside of the internal support rod to move along the inner wall of the aluminum bronze tube. When encountering a bending position, under the action of pressure, the internal support rod is squeezed and deformed against the inner wall of the aluminum bronze tube, so that the shape of the internal support rod matches the bending shape of the aluminum bronze tube. When the aluminum bronze tube passes through the internal support rod and is positioned against the surface of one end of the rotating rod, it is complete. The surface of one end of the synchronous partition plate will squeeze the airbag block. The airbag block will be squeezed and deformed, clamping one end of the aluminum bronze tube. The synchronous connecting fixing plate will move and engage with the surface of one end of the base platform. Then, the cylinder telescopic rod will extend and retract, driving the connecting positioning plate to move inward. This will drive the roller connecting block to move inward along the sliding limiting groove through the connecting limiting rod. This will allow the limiting roller on one side of the roller connecting block to slide steadily inward along the limiting roller groove. This will allow the straightening roller to accurately roll along the outside of the aluminum bronze tube to roll and straighten the bent part. During the rolling and straightening process, the internal support rod will support the inside of the aluminum bronze tube, which will help prevent the inner cavity of the aluminum bronze tube from deforming during the rolling and straightening process. This will facilitate the straightening of multiple aluminum bronze tubes at one time, improve the straightening efficiency, and make the straightening process more convenient. It will also help prevent the inner cavity of the aluminum bronze tube from being squeezed and deformed during the straightening process.

[0016] 2. Through the designed protective auxiliary mechanism, during use, the motor drives the rotating rod to rotate, which in turn drives the internal support rod of the aluminum bronze tube to rotate 90 degrees to roll and straighten the next set of aluminum bronze tubes. When the internal support rod of the aluminum bronze tube rotates 120 to 130 degrees, when one end of the aluminum bronze tube is not obstructed, the aluminum bronze tube slides into the finished product discharge trough along the pulley installed on the outside of the internal support rod and the inclination angle of the internal support rod. It slides out of the finished product discharge trough, and the staff can collect and place the aluminum bronze tubes at the discharge point. This facilitates the discharge and feeding of the straightened aluminum bronze tubes, making the discharge and feeding process more convenient and labor-saving, and saving time for retrieving the straightened aluminum bronze tubes.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a straightening mechanism for aluminum bronze tubes, including a base platform 1, a feeding and shrinking mechanism 3 provided in the middle of one end of the base platform 1, a connecting and fixing plate 2 provided at one end of the feeding and shrinking mechanism 3, a straightening mechanism 4 provided at the top of the connecting and fixing plate 2, and a protective auxiliary mechanism 5 provided at one end of the top of the base platform 1.

[0027] The straightening mechanism 4 includes a connecting positioning plate 41, a cylinder telescopic rod 42 connected to one end of the connecting positioning plate 41, a roller connecting block 43 fixedly connected to the bottom end of the connecting positioning plate 41, a connecting limiting rod 410 fixedly connected to the middle of the bottom end of the roller connecting block 43, a straightening roller 44 rollingly connected to the inner side of the roller connecting block 43, a limiting roller 45 fixedly connected to one side of the roller connecting block 43, a limiting roller groove 46 slidably connected to the outer side of the limiting roller 45, a sliding limiting groove 49 slidably connected to the outer side of the bottom end of the roller connecting block 43, a limiting baffle 47 fixedly connected to the outer side of the limiting roller groove 46, and a partition plate 48 fixedly connected to the top end of the connecting fixing plate 2.

[0028] In this implementation scheme, the designed straightening mechanism 4, when in use, is driven by the extension and retraction of the cylinder telescopic rod 42 to move the connecting positioning plate 41 inward, thereby driving the roller connecting block 43 to move inward along the sliding limiting groove 49 via the connecting limiting rod 410. This allows the limiting roller 45 on one side of the roller connecting block 43 to slide steadily inward along the limiting roller groove 46, so that the straightening roller 44 accurately rolls along the outside of the aluminum bronze tube to roll and straighten the bent parts. This results in good stability of the rolling and straightening, which is beneficial to improving the straightening efficiency, preventing the sliding trajectory from shaking or deviating during straightening, and improving the accuracy of sliding positioning during straightening.

[0029] Specifically, the protective auxiliary mechanism 5 includes a rotating rod 51, with internal support rods 52 at three nodes on the outer side of the rotating rod 51. A finished product conveying trough 53 is fixedly connected to the other end of the base platform 1. Support columns 55 are fixedly connected to both sides of the top of the base platform 1. A motor 54 is provided at the top of one side of the support column 55. The output end of the motor 54 is fixedly connected to one side of the rotating rod 51. Mounting grooves 56 are fixedly connected at four nodes on the outer side of the internal support rod 52. A pulley 57 is installed on the inner side of the mounting groove 56. An airbag block 58 is fixedly connected to one end of the internal support rod 52.

[0030] In this implementation scheme, the designed protective auxiliary mechanism 5, when in use, is driven by a motor 54 to rotate a rotating rod 51, which in turn drives the internal support rod 52, which is fitted with an aluminum bronze tube, to rotate 90 degrees to roll and straighten the next set of aluminum bronze tubes. When the internal support rod 52, fitted with an aluminum bronze tube, rotates 120 to 130 degrees, and when one end of the aluminum bronze tube is not obstructed, the aluminum bronze tube slides into the finished product discharge trough 53 along the pulley 57 installed on the outside of the internal support rod 52 and the inclination angle of the internal support rod 52. It then slides out of the finished product discharge trough 53, and the workers can then organize and place the aluminum bronze tubes at the discharge point. This facilitates the feeding of the straightened aluminum bronze tubes, making the feeding process more convenient and labor-saving, and saving time in retrieving the straightened aluminum bronze tubes.

[0031] Specifically, the feeding and shrinking mechanism 3 includes a shrinking rod 31, one end of which is fixedly connected to one end of the connecting and fixing plate 2. A buffer spring 32 is provided on the outside of the shrinking rod 31. A protective box 33 is fixedly connected to the top of one end of the connecting and fixing plate 2. The top of the protective box 33 is fixedly connected to the bottom of the limiting baffle 47. Track grooves 34 are fixedly connected to both sides of the middle part of the top of the base platform 1.

[0032] In this embodiment, the designed feeding and shrinking mechanism 3, when in use, the shrinking rod 31 shrinks and drives the connecting fixing plate 2 to move inward, so that the track block fixedly connected to the bottom of the protective box 33 slides steadily inward along the track groove 34, thereby driving the aluminum bronze tube placed at the top of the protective box 33 to slowly fit onto the outer surface of the internal support rod 52. This facilitates the fitting of the aluminum bronze tube onto the outside of the internal support rod 52, which helps to improve the stability of the sliding of the connecting fixing plate 2 and the protective box 33, and helps to prevent the sliding position of the connecting fixing plate 2 and the protective box 33 from shifting.

[0033] Specifically, an auxiliary roller is fixedly connected to the bottom of the connecting plate 2, and an auxiliary roller groove is provided on the outer side of the auxiliary roller. A track block is fixedly connected to the bottom of the protective box 33. The track block is slidably connected to the track groove 34. There is one set of track grooves 34, one set of track blocks, one set of auxiliary rollers, and one set of auxiliary roller grooves.

[0034] In this embodiment, the designed track groove 34, track block, auxiliary roller and auxiliary roller groove are beneficial to saving the force of sliding contraction, improving the stability of sliding contraction, preventing the connecting fixing plate 2 and the protective box 33 from shaking during sliding adjustment, and improving the accuracy of the sliding trajectory.

[0035] Specifically, there are three sets of connecting limit rods 410, three sets of roller connecting blocks 43, multiple sets of straightening rollers 44, and one set of connecting positioning plates 41.

[0036] In this embodiment, the designed limit rod 410 and roller connecting block 43 facilitate the installation and fixing of a set of connecting positioning plates 41 together, making it easy for the set of connecting positioning plates 41 to form a whole, and making it easy to adjust the position of the connecting positioning plates that form a whole.

[0037] Specifically, there are multiple sets of limiting rollers 45, multiple sets of limiting roller grooves 46, and a sliding limiting cavity is provided on the outer side of the bottom end of the connecting limiting rod 410.

[0038] In this embodiment, the designed limiting roller 45 and limiting roller groove 46 help prevent the sliding position of the rolling straightening from shifting during use, and help improve the accuracy of the moving position of the straightening roller 44 during rolling straightening.

[0039] Specifically, there are multiple sets of mounting slots 56, multiple sets of pulleys 57, a cavity on the inner side of the airbag block 58, a cavity in the middle of the inner side of the internal support rod 52, an air inlet fixedly connected to the bottom of the inner side of the mounting slot 56, the air inlet communicating with the cavity on the inner side of the internal support rod 52, and a through hole fixedly connected to one end of the inner side of the airbag block 58, the through hole communicating with the cavity on the inner side of the internal support rod 52.

[0040] In this embodiment, it is convenient to allow air to enter and exit the airbag block 58, and to allow the airbag block to retract and fold to limit the position of the aluminum bronze tube.

[0041] Working principle: In use, the bent aluminum bronze tube is placed into the groove formed by the limiting baffle 47, so that one end of the aluminum bronze tube is attached to the surface of one end of the partition plate 48, and the other end of the aluminum bronze tube is attached to one end of the internal support rod 52. After placement, the retraction rod 31 retracts, causing the connecting fixing plate 2 to move inward, so that the track block fixedly connected to the bottom of the protective box 33 slides steadily inward along the track groove 34, thereby causing the aluminum bronze tube placed at the top of the protective box 33 to slowly slide onto the outer surface of the internal support rod 52. This causes the pulley 57 installed in the mounting groove 56 on the outer side of the internal support rod 52 to move along the inner wall of the aluminum bronze tube. When encountering a bending position, under the action of pressure, the internal support rod 52 is squeezed and deformed against the inner wall of the aluminum bronze tube, causing it to bend. The shape of the internal support rod 52 matches the bending shape of the aluminum bronze tube. When the aluminum bronze tube passes through the internal support rod 52 and is positioned against the surface of one end of the rotating rod 51, the surface of one end of the synchronous partition plate 48 will squeeze the airbag block 58. The airbag block 58 is squeezed and deformed, clamping one end of the aluminum bronze tube. The synchronous connecting fixing plate 2 will move and engage with the surface of one end of the base platform 1. Then, the cylinder telescopic rod 42 will extend and retract, driving the connecting positioning plate 41 to move inward. This will drive the roller connecting block 43 to move inward along the sliding limiting groove 49 through the connecting limiting rod 410. This will cause the limiting roller 45 on one side of the roller connecting block 43 to slide steadily inward along the limiting roller groove 46, allowing the straightening roller 44 to accurately roll along the outer side of the aluminum bronze tube to bend. The folded portion is straightened by rolling. During the rolling straightening process, the internal support rod 52 supports the interior of the aluminum bronze tube, which helps to prevent the inner cavity of the aluminum bronze tube from deforming during the rolling straightening. After the rolling straightening is completed, the cylinder telescopic rod 42 extends and retracts, driving the connecting positioning plate 41 to move inward. This, in turn, drives the roller connecting block 43 to move outward along the sliding limit groove 49 via the connecting limit rod 410. This allows the limit roller 45 on one side of the roller connecting block 43 to slide steadily outward along the limit roller groove 46, performing a second rolling straightening of the aluminum bronze tube. After the second rolling straightening is completed, the retraction rod 31 pushes the connecting fixing plate 2 to move outward, driving the protective box 33 to move outward. During the outward movement of the protective box 33, one end of the aluminum bronze tube is retracted and folded. The airbag block 58 blocks the aluminum bronze tube, which helps prevent it from slipping off the internal support rod 52. When the protective box 33 moves to its original position, the airbag block 58 will slowly return to its original shape without being squeezed. The motor 54 drives the rotating rod 51 to rotate, which in turn drives the internal support rod 52, which is fitted with the aluminum bronze tube, to rotate 90 degrees to roll and straighten the next set of aluminum bronze tubes. When the internal support rod 52 fitted with the aluminum bronze tube rotates 120 to 130 degrees, when one end of the aluminum bronze tube is not blocked, the aluminum bronze tube slides into the finished product discharge trough 53 along the pulley 57 installed on the outside of the internal support rod 52 and the inclination angle of the internal support rod 52. It then slides out of the finished product discharge trough 53, and the workers collect and place the aluminum bronze tubes at the discharge point.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
