Abstract
Description
Technical Field
[0001] This application relates to the field of copper tube bending and forming technology, and in particular to an auxiliary bending mechanism for large-size copper tubes. Background Technology
[0002] Copper pipe, also known as red copper pipe, is a type of non-ferrous metal pipe. It is a seamless pipe produced by pressing and drawing. Copper pipe has excellent electrical and thermal conductivity, making it a primary material for conductive and heat dissipation components in electronic products. It has also become the first choice for modern contractors in installing water supply, heating, and cooling pipes in all residential and commercial buildings.
[0003] Due to the large production volume and usage of copper tubes, production is often carried out in large-scale continuous production. Therefore, during storage, copper tubes are often transported or stored by winding them onto winding reels. Small-diameter copper tubes can usually be wound directly after heat treatment, while large-diameter copper tubes often require multiple people to guide and assist them during winding. If the bending radius is too small, the copper tube can easily be damaged.
[0004] However, conventional bending methods are very labor-intensive, requiring operators to support the copper tube for extended periods and bend it until it is correctly folded onto the winding reel. Furthermore, manual bending of the copper tube lacks precise control over the winding radius, significantly impacting the bending accuracy, and therefore requires improvement. Utility Model Content
[0005] To improve the efficiency and quality of winding large-diameter copper tubes, this application provides an auxiliary bending mechanism for large-size copper tubes.
[0006] The auxiliary bending mechanism for large-size copper tubes provided in this application adopts the following technical solution:
[0007] A large-size copper tube auxiliary bending mechanism includes a support column, a conveying assembly, a bending assembly, an auxiliary forming assembly, and multiple storage assemblies. The conveying assembly is disposed on one side of the support column, the bending assembly is disposed at one end of the conveying assembly near the support column, and the auxiliary forming assembly is mounted above the bending assembly. A multi-head crossbeam is rotatably disposed on the support column. The multi-head crossbeam includes multiple ends arranged radially along the support column, and a storage assembly is installed on each end of the multi-head crossbeam. The auxiliary forming assembly is used to wind the copper tube around the storage assembly.
[0008] By adopting the above technical solution, the end of the copper tube is conveyed horizontally towards the support column via a conveying assembly. When the end of the copper tube moves to the bending assembly, the bending assembly bends the end of the copper tube upwards in an arc shape and enters the auxiliary forming assembly. At this time, the multi-head crossbeam controls one of the receiving assemblies to be located inside the auxiliary forming assembly, and the auxiliary forming assembly controls the end of the copper tube to wind around the receiving assembly. When this winding is completed, the operator cuts the copper tube at the conveying assembly, and the multi-head crossbeam controls the receiving assembly to leave the auxiliary forming assembly. At the same time, the next receiving assembly is moved into the auxiliary forming assembly for the next winding. Compared with the traditional process that requires a lot of manual labor for bending, this method improves the efficiency of winding large-diameter copper tubes, reduces the demand for manual labor, improves the safety of the production process, and ensures the quality of winding large-diameter copper tubes.
[0009] Optionally, the auxiliary forming component includes a mounting frame, a linear motion module, a rotary drive, a forming ring, and a clamping component. The mounting frame is fixedly connected to the support column. The fixed end of the linear motion module is mounted on the mounting frame. The rotary drive is located at the movable end of the linear motion module and drives the forming ring to rotate around the receiving component. The clamping component is mounted on the forming ring and is used to clamp the end of the copper tube.
[0010] Optionally, the rotary drive component includes a movable plate, multiple drive gears, and multiple transmission pulleys. The movable plate is fixedly mounted on the movable end of the linear motion module. The drive gears drive the movable plate to move closer to or away from the mounting frame. The movable plate has a notch adapted to the forming ring. The multiple drive gears and transmission pulleys are circumferentially rotatably disposed at the notch. The drive gears are rotatably disposed on the side wall of the movable plate close to the mounting frame, and the transmission pulleys are rotatably disposed on the side wall of the movable plate away from the mounting frame. Each drive gear is fixedly connected to a transmission pulley via a rotating shaft passing through the movable plate to achieve synchronous rotation. The forming ring is disposed on the side wall of the movable plate close to the mounting frame, and teeth are provided on the outer peripheral wall of the forming ring to mesh with the multiple drive gears.
[0011] Optionally, the rotary drive component further includes a drive screw and a rotating wheel. The drive screw is arranged along the length direction parallel to the linear movement module. The drive screw is rotatably connected to the mounting frame through a rotating seat. The rotating wheel is sleeved on the drive screw, and the inner peripheral wall of the rotating wheel is rotatably engaged with the drive screw. A circular hole is provided on the movable plate, and the rotating wheel is rotatably mounted in the circular hole on the movable plate through a bearing. The rotating wheel rotates synchronously with one of the transmission pulleys through a belt.
[0012] By adopting the above technical solution, the linear motion module controls the movable plate to be located at one end near the mounting frame, and the rotating wheel is located at the end of the drive screw near the mounting frame, with the notch on the forming ring facing upwards. The multi-head beam controls one of the receiving components to rotate to the notch on the forming ring. When the bent end of the copper tube leaves the top of the second stop, the clamping component extends out of the forming ring to clamp it. The linear motion module controls the movable plate to move away from the mounting frame. The rotating wheel rotates under the action of the drive screw, driving the transmission pulley and drive gear to rotate. The drive gear rotates, causing the forming ring to rotate around the receiving component. The forming ring drives the clamping component to rotate circumferentially, guiding the copper tube to wind onto the receiving component to form a copper tube coil. After one winding is completed, the operator cuts the copper tube and puts a leather sleeve on the new end of the subsequent copper tube to prevent the end of the copper tube from abrading the first stop and to facilitate clamping by the clamping component. The clamping element releases the copper tube end and retracts onto the forming ring. The linear movement module controls the movable plate to return to its end closest to the mounting bracket. The multi-head crossbeam rotates clockwise, and this receiving assembly drives the copper tube coil away from the forming ring. Simultaneously, it moves the next empty receiving assembly above the forming ring for the next winding. This improves the efficiency of winding large-diameter copper tubes, reduces the need for manual labor, and ensures the quality of winding large-diameter copper tubes.
[0013] Optionally, the forming ring is provided with a notch, and when the notch on the forming ring faces upward, it can make way for the multi-head crossbeam and the storage component.
[0014] Optionally, the clamping component includes a control frame, two clamping plates, two connecting rods, and a clamping cylinder. The control frame is fixedly installed on the side wall of the forming ring near the mounting frame. The two clamping plates are slidably engaged with the control frame. The clamping cylinder is fixedly installed on the control frame. A rotating shaft is installed on the cylinder shaft of the clamping cylinder. One end of the connecting rod is rotatably connected to the rotating shaft, and the other end is connected to one of the clamping plates.
[0015] By adopting the above technical solution, in the initial state, the cylinder shaft of the clamping cylinder retracts, the two clamping plates are far apart from each other, and the edges of the clamping plates do not protrude from the inner wall of the forming ring. When clamping is required, the cylinder shaft of the clamping cylinder extends, driving the two clamping plates to extend forward and move closer to each other, and the two clamping plates clamp onto the leather sleeve fitted on the end of the copper tube.
[0016] Optionally, the storage assembly includes two support rollers, a storage motor, and a safety frame. One end of each support roller is rotatably connected to a multi-head crossbeam. A drive sprocket is mounted on the support roller. The storage motor is fixedly mounted on the multi-head crossbeam. A drive sprocket is mounted on the output shaft of the storage motor. The storage motor drives the two support rollers to rotate via the sprocket and chain. Multiple annular grooves are provided on the outer peripheral wall of each support roller, and the multiple annular grooves are spaced apart along the length of the support roller. The safety frame is fixedly mounted on the multi-head crossbeam and located below the support rollers.
[0017] By employing the above technical solution, the two support rollers on one of the multi-beam control sections are positioned above the notch in the forming ring. When the forming ring carries the copper tube over the support rollers, the copper tube rests on the support rollers, which support its weight. Simultaneously, the winding motor drives the two support rollers to rotate in the same direction as the forming ring via a drive sprocket. Under the action of friction, the copper tube coil follows the rotation of the forming ring. The safety frame protects the copper tube coil, preventing it from falling due to accidents.
[0018] Optionally, the conveying assembly includes a worktable, a support plate, conveying wheels, and pressure rollers. The worktable is fixedly mounted on a support column, and the support plate is fixedly mounted on the worktable. Multiple conveying wheels are provided, and each conveying wheel is rotatably mounted on the support plate and driven by a motor. The conveying wheels clamp the copper tube from above and below. The pressure roller is positioned above the copper tube. The bending assembly includes a movable vertical plate, a bending cylinder, a bending wheel, a first stop, and a second stop. The movable vertical plate is raised and lowered and slidably mounted on the worktable. The bending cylinder is fixedly mounted on the worktable, and its cylinder shaft is fixedly connected to the movable vertical plate. The bending wheel is rotatably connected to the movable vertical plate and is located below the copper tube. Both the first and second stops are mounted on a mounting frame. The copper tube passes through the arc-shaped channel formed between the first and second stops, and the end of the copper tube undergoes preliminary straightening by sequentially passing through the first and second stops.
[0019] By adopting the above technical solution, a continuous copper tube is sandwiched between conveying wheels. Under the action of friction, the copper tube is controlled to approach the support column. When the end of the copper tube reaches above the bending wheel, the bending cylinder drives the movable vertical plate to rise, and the bending wheel bends the end of the copper tube upward. At this time, the pressure wheel controls the shape of the copper tube from behind. After being bent, the end of the copper tube moves upward along the arc until it enters the channel between the first stop and the second stop. The end of the copper tube first contacts the side wall of the first stop for the first correction, and then contacts the side wall of the second stop for the second correction. After the two corrections, it reaches a relatively standard circle, and finally moves upward along the side wall of the second stop.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The end of the copper tube is conveyed horizontally towards the support column via a conveying assembly. When the end of the copper tube reaches the bending assembly, the bending assembly bends the end of the copper tube upwards in an arc shape and enters the auxiliary forming assembly. At this time, a multi-head crossbeam controls one of the receiving assemblies to be located inside the auxiliary forming assembly. The auxiliary forming assembly controls the end of the copper tube to wind around the receiving assembly. When this winding is completed, the operator cuts the copper tube at the conveying assembly. The multi-head crossbeam controls the receiving assembly to leave the auxiliary forming assembly, and at the same time, the next receiving assembly is moved into the auxiliary forming assembly for the next winding. Compared with the traditional process that requires a lot of manual labor for bending, this method improves the efficiency of winding large-diameter copper tubes, reduces the need for manual labor, improves the safety of the production process, and ensures the quality of winding large-diameter copper tubes.
[0022] 2. The linear motion module controls the movable plate at its end closest to the mounting bracket, and the rotating wheel at the end of the drive screw closest to the mounting bracket, with the notch on the forming ring facing upwards. The multi-head beam controls one of the receiving components to rotate to the notch on the forming ring. When the bent end of the copper tube leaves the top of the second stop, the clamping component extends out of the forming ring to hold it. The linear motion module controls the movable plate to move away from the mounting bracket. The rotating wheel rotates under the action of the drive screw, driving the transmission pulley and drive gear to rotate. The drive gear rotates, causing the forming ring to rotate around the receiving component. The forming ring drives the clamping component to rotate circumferentially, guiding the copper tube to wind onto the receiving component to form a copper tube coil. After one winding is completed, the operator cuts the copper tube and places a leather sleeve on the new end of the subsequent copper tube to prevent the end of the copper tube from abrading the first stop and to facilitate clamping by the clamping component. The clamping component releases the copper tube end and retracts onto the forming ring. The linear movement module controls the movable plate to return to its end closest to the mounting bracket. The multi-head crossbeam rotates clockwise, and this receiving component drives the copper tube coil away from the forming ring. Simultaneously, it moves the next empty receiving component above the forming ring for the next winding. This improves the efficiency of winding large-diameter copper tubes, reduces the need for manual labor, and ensures the quality of winding large-diameter copper tubes.
[0023] 3. The multi-beam control system uses two support rollers on one of the beams positioned above the notch in the forming ring. As the forming ring carries the copper tube over the support rollers, the copper tube rests on them, supported by the rollers to bear its weight. Simultaneously, the drive motor drives the two support rollers to rotate in the same direction as the forming ring via a drive sprocket. Under the influence of friction, the copper tube coil follows the rotation of the forming ring. A safety frame protects the copper tube coil, preventing it from falling due to accidents.

[0034] This application discloses an auxiliary bending mechanism for large-size copper tubes. (Refer to...) Figure 1 and Figure 2A large-size copper tube auxiliary bending mechanism includes a support column 1, a conveying assembly 2, a bending assembly 3, an auxiliary forming assembly 4, and multiple storage assemblies 5. The conveying assembly 2 is disposed on one side of the support column 1, the bending assembly 3 is disposed at the end of the conveying assembly 2 near the support column 1, and the auxiliary forming assembly 4 is mounted above the bending assembly 3. A multi-head crossbeam 6 is rotatably disposed on the support column 1, and the rotation of the multi-head crossbeam 6 is driven by a reducer 7. The multi-head crossbeam 6 includes multiple ends arranged radially along the support column 1, and a storage assembly 5 is installed on each end of the multi-head crossbeam 6. In this embodiment, the multi-head crossbeam 6 is a crossbeam.
[0035] The end of the copper tube is conveyed horizontally towards the support column 1 via the conveying assembly 2. When the end of the copper tube moves to the bending assembly 3, the bending assembly 3 bends the end of the copper tube upwards in an arc shape and enters the auxiliary forming assembly 4. At this time, the multi-head beam 6 controls one of the receiving assemblies 5 to be located inside the auxiliary forming assembly 4. The auxiliary forming assembly 4 controls the end of the copper tube to be wound around the receiving assembly 5. When this winding is completed, the operator cuts the copper tube at the conveying assembly 2, and the multi-head beam 6 controls the receiving assembly 5 to leave the auxiliary forming assembly 4. At the same time, the next receiving assembly 5 is moved into the auxiliary forming assembly 4 for the next winding. Compared with the traditional process that requires a lot of manual labor for bending, this method improves the efficiency of winding large-diameter copper tubes, reduces the need for manual labor, improves the safety of the production process, and ensures the quality of winding large-diameter copper tubes.
[0036] Reference Figure 3 The storage assembly 5 includes two support rollers 51, a storage motor 52, and a safety frame 53. One end of each support roller 51 is rotatably connected to a multi-head beam 6. A drive sprocket 54 is mounted on each support roller 51. The storage motor 52 is fixedly mounted on the multi-head beam 6, and the drive sprocket 54 is mounted on the output shaft of the storage motor 52. The storage motor 52 drives the two support rollers 51 to rotate via the sprocket and chain. Multiple annular grooves 55 are provided on the outer peripheral wall of each support roller 51, and these grooves are spaced apart along the length of the support roller 51. The safety frame 53 is fixedly mounted on the multi-head beam 6 and located below the support rollers 51.
[0037] The multi-head crossbeam 6 controls two support rollers 51 on one of the crossbeams to be positioned above the auxiliary forming component 4. When the auxiliary forming component 4 drives the copper tube over the support rollers 51, the copper tube rests on the support rollers 51, and the support rollers 51 support the weight of the copper tube. At the same time, the storage motor 52 drives the two support rollers 51 to rotate in the same direction through the drive sprocket 54, and the copper tube coil rotates along with it under the action of friction. The safety frame 53 can protect the copper tube coil and prevent it from falling due to accidents.

The cylinder shaft of the bending cylinder 32 is fixedly connected to the movable vertical plate 31. The bending wheel 33 is rotatably connected to the movable vertical plate 31 and is located below the copper tube.
[0040] The first stop 34 and the second stop 35 are both fixedly installed. The copper tube passes through the arc-shaped channel formed between the first stop 34 and the second stop 35, and the end of the copper tube is initially corrected by passing through the first stop 34 and the second stop 35 in sequence.
[0041] A continuous copper tube is sandwiched between conveyor rollers 23. Friction forces control the copper tube to approach the support column 1. When the end of the copper tube reaches above the bending roller 33, the bending cylinder 32 drives the movable vertical plate 31 to rise. The bending roller 33 bends the end of the copper tube upwards. At this time, the pressure roller 24 controls the shape of the copper tube from behind. After bending, the end of the copper tube moves upwards along an arc until it enters the channel between the first stop block 34 and the second stop block 35. The end of the copper tube first contacts the side wall of the first stop block 34 for the first correction, then contacts the side wall of the second stop block 35 for the second correction. After two corrections, it reaches a relatively standard circle, and finally moves upwards along the side wall of the second stop block 35.
[0042] Reference Figure 6 and Figure 7 The auxiliary forming component 4 includes a mounting frame 41, a linear movement module 42, a rotary drive component 43, a forming ring 44, and a clamping component 45. The mounting frame 41 is fixedly connected to the support column 1. The fixed end of the linear movement module 42 is mounted on the mounting frame 41. The rotary drive component 43 is located at the movable end of the linear movement module 42 and drives the forming ring 44 to rotate around the storage component 5. The clamping component 45 is mounted on the forming ring 44 and is used to clamp the end of the copper tube. The forming ring 44 has a notch. When the notch on the forming ring 44 faces upward, it can make way for the multi-head crossbeam 6 and the storage component 5.
[0043] Reference Figure 6 and Figure 7The rotary drive component 43 includes a movable plate 431, multiple drive gears 432, and multiple transmission pulleys 433. The movable plate 431 is fixedly mounted on the movable end of the linear motion module 42. The drive gears 432 drive the movable plate 431 to move closer to or away from the mounting frame 41. The movable plate 431 has a notch adapted to the forming ring 44. The multiple drive gears 432 and transmission pulleys 433 are rotatably arranged at the notch. The drive gears 432 are rotatably arranged on the side wall of the movable plate 431 near the mounting frame 41, and the transmission pulleys 433 are rotatably arranged on the side wall of the movable plate 431 away from the mounting frame 41.

The multi-head beam 6 controls one of the receiving components 5 to rotate to the notch located on the forming ring 44. When the bent end of the copper tube leaves the top of the second stop 35, the clamping member 45 extends out of the forming ring 44 to clamp it. The linear motion module 42 controls the movable plate 431 to move away from the mounting bracket 41. The rotating wheel 435 rotates under the action of the drive screw 434. The rotation of the rotating wheel 435 drives the transmission pulley 433 and the drive gear 432 to rotate. The rotation of the drive gear 432 drives the forming ring 44 to rotate around the receiving component 5. The forming ring 44 drives the clamping member 45 to rotate around its circumference, guiding the copper tube to be wound around the receiving component 5 to form a copper tube coil. After one winding is completed, the operator cuts the copper tube and places a leather sleeve on the new end of the subsequent copper tube to prevent the end of the copper tube from abrading the first stop 34 and to facilitate clamping by the clamping component 45. The clamping component 45 releases the end of the copper tube and retracts it onto the forming ring 44. The linear movement module 42 controls the movable plate 431 to return to its end near the mounting bracket 41. The multi-head crossbeam 6 rotates clockwise, and this receiving component 5 drives the copper tube coil away from the forming ring 44. At the same time, the next empty receiving component 5 is moved above the forming ring 44 for the next winding. This improves the efficiency of winding large-diameter copper tubes, reduces the need for manual labor, and ensures the quality of winding large-diameter copper tubes.
