Description

Technical Field

[0001] This invention relates to the field of copper tube production and processing technology, specifically to a traverse mechanism for coiling and a continuous winding system. Background Technology

[0002] Planetary rolling and linear drawing are two important production processes on a continuous casting and rolling production line for tube blanks, both involving metal deformation to reduce the diameter and wall thickness of the tube blank. Planetary rolling and drawing are two consecutive production processes, but their production processes and speeds differ. Therefore, generally, the rolled tube blank is first coiled, and then drawn and uncoiled. In existing technology, to facilitate simultaneous coiling and drawing, a coiling / uncoiling device with a coiling station, a transfer station, and an uncoiling station is set up. Each station has a pair of support rollers, and all support rollers are mounted on a rotating coiling / uncoiling frame. The rotation of the coiling / uncoiling frame controls the transfer of the coiled copper coil to the next station. However, because the coiling station cannot coil while the coiling / uncoiling frame is rotating, and the uncoiling station cannot uncoil, continuous production of copper tubes cannot be achieved, reducing production efficiency.

[0003] The prior art patent publication number CN114653778A discloses a continuous transfer winding and unwinding device and method, which sets up a first station mechanism and a second station mechanism between the rolling mill and the drawing machine. Both the first station mechanism and the second station mechanism have two sets of winding rollers (i.e., support rollers). Each set of winding rollers can be used to wind or unwind copper tubes. The two sets of winding rollers in the same station mechanism can rotate 180° to facilitate winding / heading / unwinding of the copper coil on the winding rollers. In application, after one set of winding rollers in one station mechanism completes the winding of the copper tube, the other set of winding rollers in the other station mechanism is used for a new winding of the copper tube. One set of the remaining two sets of winding rollers is used to head the copper coil, and the other set is used to unwind the copper tube for the drawing machine. The whole process ensures the continuity of copper tube production. However, this winding and unwinding equipment occupies a large area, and each set of winding rollers has a corresponding lifting guide rail mechanism and gripper mechanism. Each station mechanism has a clamping and bending machine, which makes the equipment expensive to purchase and difficult to control. In addition, its large footprint limits the application of this equipment on copper tube production lines. Summary of the Invention

[0004] The present invention aims to provide a transverse winding mechanism to solve the problem that continuous production of copper tubes cannot be achieved in the current copper tube production process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The traverse mechanism includes a support roller, a lifter, an axial mover, and a mover. The support roller is horizontally positioned and installed at the output end of the lifter. The axial mover is used to drive the lifter to move axially along the support roller. The axial mover is installed on the mover and is used to drive the axial mover to move.

[0007] The principle and advantages of this scheme are as follows: Using this scheme, the support roller is moved into the copper coil by the movement of the mover and the axial transfer machine. Then, the lifting device is controlled to move the support roller upwards, completely lifting the copper coil placed on the support roller. Next, the axial transfer machine is controlled to move the lifting device, support roller, and copper coil together along the axial direction of the support roller, completely removing the copper coil from the support roller. The mover is then controlled to move the copper coil to its destination. Finally, the axial transfer machine again moves the copper coil close to the support roller on the storage rack, and the lifting device is controlled to descend, placing the copper coil on the support roller on the storage rack, completing the transfer of the copper coil. Throughout this process, the support roller on the winding rack of the copper coil is unaffected by subsequent processes, thus maintaining continuous production and ensuring the continuity of copper tube production, which is beneficial for improving copper tube production efficiency.

[0008] Preferably, as an improvement, the outer circumference of the support roller is provided with a spiral groove, which separates adjacent turns of copper tubes in the copper coil and avoids friction between the copper tubes.

[0009] Preferably, as an improvement, the number of support rollers is two, so that the copper coil can be stably supported during the transfer process.

[0010] Preferably, as an improvement, the axial removal machine is a linear slide table, which is fixed on the top of the mover. The linear slide table includes a slide rail and two sliders, which are located at different positions on the slide rail. Both sliders are slidably connected to the slide rail, and support seats are fixed on the two sliders. The lifter is installed on the support seats, and the support roller is located directly above the support seats.

[0011] Beneficial effects: This solution sets the axial removal machine as a linear slide with two sliders, which provides favorable support for the support base. The support roller is located directly above the support base, so that the weight of the copper coil is entirely distributed on the support base through the support roller, ensuring stable support for the copper coil without affecting the transfer of the copper coil by the support roller.

[0012] Preferably, as an improvement, a counterweight is also included, which is located on both sides of the center of gravity of the mover, so as to ensure that the entire traverse mechanism can operate stably without tipping over when the support roller extends out of the mover to transfer the copper coil.

[0013] The present invention also provides a continuous winding system, including the aforementioned transverse winding mechanism, and further including a winding frame and a storage frame. The transverse winding mechanism is capable of transferring copper coils from the winding frame to the storage frame. Both the winding frame and the storage frame are equipped with support rollers.

[0014] Preferably, as an improvement, the winding rack is fixedly installed, while the storage rack is rotatable. Multiple pairs of support rollers are evenly distributed around the circumference of the storage rack, each pair of support rollers used to suspend and support the copper coils. By configuring the storage rack to rotate, a greater number of copper coils can be stored on the rack, while fully utilizing the circumferential space.

[0015] Preferably, as an improvement, a bending machine is provided below both the storage rack and the transverse transfer mechanism, and both bending machines are located in the conveying direction of the copper tube.

[0016] Beneficial effects: This solution installs bending machines under both the storage rack and the traverse mechanism, enabling the copper tubes to be coiled when they enter the traverse mechanism. When the traverse mechanism is not in use due to other factors, the bending machines under the storage rack can be used to bend the copper tubes, ensuring that the coiling process is not affected and guaranteeing the normal progress of production.

[0017] Preferably, as an improvement, the bending machine includes a bending machine body and a bending guide plate. The bending guide plate is provided with a bending guide groove for guiding the copper tube to bend. The cross-section of the guide groove is U-shaped, with the U-shaped opening facing outwards from the copper coil, and the bottom opening of the guide groove facing vertically downwards. This solution allows the copper tube to pass horizontally through the bottom end of the U-shaped guide groove when neither the roll-over traversing mechanism nor the bending machine below it is working, and then the copper tube enters the bending machine below the storage rack for coiling.

[0018] Preferably, as an improvement, the storage rack has four pairs of support rollers: one pair of support rollers is used to receive the copper coil sent by the traverse mechanism, one pair of support rollers is used for head forming, one pair of support rollers is used to send it to the subsequent drawing process, and the remaining pair of support rollers is used for standby; this solution allows each of the four pairs of support rollers to have its own corresponding process.

[0028] The following detailed description illustrates the specific implementation method:

[0029] The reference numerals in the accompanying drawings include: rolling mill 10, winding rack 20, first support roller 21, storage rack 30, second support roller 31, support column 32, rotating frame 33, traverse mechanism 40, support roller 41, lifting device 42, bracket 421, guide rod 422, axial removal machine 43, slide rail 431, slider 432, support seat 433, guide sleeve 434, mover 44, wheel 441, track 442, counterweight 45, first bending machine 50, bending guide plate 51, guide slot 511, guide roller 512, upper positioning roller 52, lower positioning roller 53, lower movable roller 54, and second bending machine 60.

[0030] The basic implementation examples are as follows: Figures 1 to 9 As shown.

[0031] The continuous winding system includes a rolling mill 10, a winding rack 20, and a storage rack 30, which are fixedly arranged in sequence. The rolling mill 10 is used to roll copper tubes, the winding rack 20 is used to wind the copper tubes, and the storage rack 30 is used to store the wound copper coils. It also includes a transverse winding mechanism 40, which is used to place the wound copper coils on the winding rack 20 onto the storage rack 30, ensuring that the winding rack 20 can continuously wind copper tubes and ensuring continuous production of copper tubes.

[0032] Specifically, a pair of first retaining rollers 21 are installed on the winding frame 20, a first bending machine 50 is installed below the winding frame 20, and four pairs of second retaining rollers 31 are installed on the storage rack 30. The storage rack 30 includes a support column 32 and a rotating frame 33. The rotating frame 33 is rotatably connected to the top of the support column 32, and the four pairs of second retaining rollers 31 are rotatably connected to the rotating frame 33. One pair of second retaining rollers 31 is used to receive the copper coils sent by the traverse mechanism 40, one pair of second retaining rollers 31 is used for head forming, one pair of second retaining rollers 31 is used for sending to the subsequent drawing process, and the remaining pair of second retaining rollers 31 is for standby. The rotating frame 33 rotates intermittently. In this embodiment, the rotating frame 33 rotates 90° each time, which drives the copper coils on the pair of second retaining rollers 31 into the next process. The paired first retaining rollers 21 and the paired second retaining rollers 31 are retaining rollers of the same specification.

[0033] A second bending machine 60 is installed below the rotating frame 33. The second bending machine 60 and the first bending machine 50 are located on the same straight line, and both the second bending machine 60 and the first bending machine 50 are located in the direction of copper pipe conveying.

[0034] Both the first bending machine 50 and the second bending machine 60 include a bending machine body and a bending guide plate 51. The bending machine body is used to bend the copper tube. The bending machine body includes an upper positioning roller 52, a lower positioning roller 53, and a lower movable roller 54. The copper tube can pass between the upper positioning roller 52 and the lower positioning roller 53. The lower movable roller 54 is connected to a drive cylinder for driving the lower movable roller 54 to rise and fall. The bending guide plate 51 is located on one side of the output end of the bending machine body, combined with... Figure 3 The bending guide plate 51 has a curved guide groove 511 machined on it. The guide groove 511 is used to guide the bending of the copper tube. The cross-section of the guide groove 511 is U-shaped, with the U-shaped opening facing outwards from the copper coil. The bottom opening of the guide groove 511 is vertically downwards. In this embodiment, to ensure smoother movement of the copper tube along the guide groove 511, a freely rotatable guide roller 512 is installed at the bottom of the guide groove 511. The lower movable roller 54 rises under the action of the driving cylinder, thereby lifting the copper tube upwards. The copper tube bends and then curves upwards into the guide groove 511 of the bending guide plate 51, moving along the curved guide groove 511 of the bending guide plate 51. Finally, it is wound onto the corresponding support roller, completing the coiling of the copper tube.

[0035] When the first bending machine 50 is not working, the copper tube enters the second bending machine 60 for bending after passing through the bottom openings of the upper positioning roller 52, lower positioning roller 53, and guide groove 511 of the first bending machine 50.

[0036] Combination Figures 5 to 7The transverse transfer mechanism 40 includes a support roller 41, a lifter 42, an axial transfer mechanism 43, and a mover 44. The outer circumference of the support roller 41 is machined with spiral grooves to separate adjacent copper tubes. There are two support rollers 41 and two lifters 42. The two support rollers 41 are horizontally arranged. The size of the two support rollers 41 is smaller than the size of the support roller. The distance between the two support rollers 41 is smaller than the distance between the two pairs of first support rollers 21. Both lifters 42 are vertically arranged cylinders. The top of the output end of the two lifters 42 is fixedly mounted with a bracket 421. The bracket 421 supports the support roller 41 from both ends and the middle of the support roller 41 simultaneously.

[0037] The axial removal machine 43 is a linear slide table, which is fixedly installed on the mover 44. The linear slide table is used to drive the lifter 42 to move axially along the support roller 41. The linear slide table is fixed on the top of the mover 44. The linear slide table includes a first driver, a slide rail 431 and two sliders 432. The two sliders 432 are located at different positions on the slide rail 431. Both sliders 432 are slidably connected to the slide rail 431. The first driver is used to drive the sliders 432 to move on the slide rail 431. The first driver can be a lead screw drive. The top of the two sliders 432 is fixedly supported by a support base 433. The lifter 42 is located above the support base 433 and fixedly installed on the support base 433. The support roller 41 is located directly above the support base 433. In this embodiment, to ensure the stable lifting and lowering of the bracket 421 supported by the lifter 42, a guide rod 422 is fixedly installed at the bottom of the bracket 421, and a guide sleeve 434 is fixedly installed on the support base 433. The guide rod 422 is vertically slidably connected inside the guide sleeve 434.

[0038] The mover 44 is used to move the linear slide so that the two support rollers 41 can be inserted between the first host rollers 21 of the winding frame 20, and also so that the support rollers 41 can be inserted between the pairs of second host rollers 31 of the storage rack 30.

[0039] The mover 44 includes a second drive, a wheel 441 and a track 442 located below the wheel 441. The track 442 is fixed to the ground. The second drive is used to make the mover 44 travel on the track 442. The length direction of the track 442 is perpendicular to the axis of the support roller 41, and the axis of the support roller 41 is perpendicular to the copper pipe conveying direction.

[0040] A counterweight 45 is fixed on the mover 44. The counterweight 45 and the support roller 41 are located on both sides of the center of gravity of the mover 44. In this embodiment, the counterweight 45 and the support roller 41 are located on both sides of the track 442.

[0041] Combination Figure 8 and Figure 9 The specific process of this embodiment is as follows:

[0042] The copper tube rolled by the rolling mill 10 is conveyed to the first bending machine 50. As the lower movable roller 54 of the first bending machine 50 is lifted, the copper tube is forced to bend. The bent copper tube moves upward along the guide groove 511 of the bending guide plate and forms a copper coil around the first support roller 21, thus the copper tube is coiled under the action of the first bending machine 50.

[0043] During the winding process of the previous copper tube, the traverse mechanism 40, under the action of the mover 44 and the axial transfer machine 43, moves the two support rollers 41 between the two first support rollers 21. After the previous copper tube is wound, the lifter 42 of the traverse mechanism 40 drives the support rollers 41 to rise, thereby lifting the copper coil originally placed on the first support rollers 21 and causing the copper coil to detach from the first support rollers 21. Then, the axial transfer machine 43 drives the lifter 42, bracket 421, and support rollers 41 on the support base 433 to move away from the winding frame 20 as a whole, ensuring that the copper tube wound on the first support rollers 21 on the winding frame 20 is transferred to the traverse mechanism 40 in a timely manner, and the first support rollers 21 on the winding frame 20 can continue to wind the copper tube, ensuring the continuity of the copper tube production process and improving the copper tube production efficiency.

[0044] Then, the traverse mechanism 40 moves along the track 442 under the activation of the mover 44 until the support roller 41 moves to the storage rack 30 between a pair of second support rollers 31 parallel to it; then the axial transfer machine 43 is activated, so that the axial transfer machine 43 drives the lifter 42, bracket 421 and support roller 41 on the support base 433 to move closer to the storage rack 30 as a whole. Finally, the output end of the lifter 42 descends, so that the copper coil on the support roller 41 is supported by the second support rollers 31, completing the transfer of the copper coil. After the transfer is completed, the traverse mechanism 40 returns to the initial position to prepare for the next copper coil transfer.

[0045] When the traverse mechanism 40 or the winding rack 20 malfunctions and cannot be used normally, as long as the lower movable roller 54 of the first bending machine 50 is kept below the copper tube, the copper tube can directly pass through the upper positioning roller 52, the lower positioning roller 53 and the guide groove 511 of the bending guide plate 51 of the first bending machine 50 and enter the second bending machine 60 below the storage rack 30 for copper tube bending. The copper tube is wound up at one of the stations of the storage rack 30, while other stations can still perform head making, tube pulling and backup, ensuring the normal progress of copper tube production.

[0046] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
