Description

[0002] The copper-clad aluminum alloy conductor is one of the types of power busbars, and the copper-clad aluminum alloy power busbar is a bimetallic conductor that realizes copper-aluminum interface metallurgical bonding through solid-liquid fusion, cladding welding and other processes, and is widely used in industrial equipment and power transmission and distribution systems. The alloy conductor usually needs to be stretched by the stretching equipment in the production process to improve the tensile strength of the alloy conductor, eliminate work hardening and the conductivity of the copper-aluminum composite profile.

[0003] The following problems in the prior art have not been well solved: 1. Since the alloy conductor is stretched by the cooperation of the movable clamp and the fixed clamp during the stretching process, and the two ends of the alloy conductor are clamped for stretching operation, there will be iron oxide scale pollution and surface adhesion of foreign matter on the surface of the clamp during long-term use, which will cause the friction coefficient to decrease.

[0017] 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.

[0018] Please see Figures 1 to 13This invention provides a technical solution: a stretching device for producing copper-clad aluminum alloy conductors, comprising: a stretching support 1, a fixed clamp 2 fixedly connected to the left side of the top of the stretching support 1, and a movable clamp 3 movably connected to the right side of the top of the stretching support 1; hydraulic cylinders 4 fixedly connected between the two sides of the movable clamp 3 and the top of the stretching support 1. It should be noted that: a guide roller is rotatably connected to the top of the stretching support 1; during the stretching process of the copper-clad aluminum alloy conductor, the stretching is performed by the guide roller; after the copper-clad aluminum alloy conductor is clamped by the fixed clamp 2 and the movable clamp 3, the hydraulic cylinders 4 are activated to move the movable clamp 3, thus stretching the copper-clad aluminum alloy conductor; both the movable clamp 3 and the fixed clamp 2 consist of an upper clamping end and a lower clamping end, ensuring stability during the clamping process of the copper-clad aluminum alloy conductor. The movable clamp 3 and the fixed clamp 2 are existing technologies and will not be described in detail.

[0019] It also includes: a movable baffle 5 that is slidably installed between the movable ends of the two hydraulic cylinders 4, and a positioning calibration mechanism 6 that is movably connected between the surface of the movable baffle 5 and the side wall of the movable clamp 3. The positioning calibration mechanism 6 is used to calibrate the end position of the copper-clad aluminum alloy conductor before stretching.

[0020] The displacement monitoring mechanism 7, which is installed inside the moving baffle 5, is used to detect the amount of displacement due to slippage. The left end of the tension bracket 1 is fixedly connected to a fixed baffle 8 that cooperates with the fixed clamp 2, and the displacement monitoring mechanism 7 is movably installed inside the fixed baffle 8. It should be noted that during the tensioning operation, the left end of the copper-clad aluminum alloy conductor overlaps with the right side of the fixed baffle 8, and the movable end of the fixed clamp 2 will not interfere with the fixed baffle 8 when it performs the clamping operation; the fixed baffle 8 and the movable baffle 5 are symmetrically arranged.

[0021] In this embodiment, as Figures 1 to 13 As shown, the positioning calibration mechanism 6 includes: a limiting ring frame 601 symmetrically fixedly connected to the surface of the moving baffle 5, and the limiting ring frame 601 movably sleeved on the moving end of the adjacent hydraulic cylinder 4. It should be noted that: the two limiting ring frames 601 are respectively fixedly connected to the front and rear sides of the moving baffle 5, and the moving baffle 5 slides between the moving ends of the two hydraulic cylinders 4 through the limiting ring frames 601 at the front and rear ends.

[0022] A transmission rod 602 is movably connected to the side wall of the movable clamp 3, and a movable gear ring 603 is movably sleeved in the middle of the transmission rod 602. The outer ring of the movable gear ring 603 is fixedly sleeved with a toggle plate 604 that cooperates with the limit ring frame 601. A compression spring 605 that cooperates with the transmission rod 602 is fixedly connected to the side wall of the movable gear ring 603.

[0023] A fixed gear ring 606 is fixedly sleeved on the surface of the transmission rod 602 and meshes with the movable gear ring 603. A U-shaped drive plate 607 is unidirectionally mounted on the end of the transmission rod 602 away from the compression spring 605. It should be noted that the teeth of the movable gear ring 603 and the fixed gear ring 606 are wedge-shaped, so that the fixed gear ring 606 can rotate synchronously with the movable gear ring 603, which is pressed by the compression spring 605. During the reset movement of the return spring at the movable end of the hydraulic cylinder 4, which carries the limit ring frame 601 and the actuating plate 604, the actuating plate 604 is reset and rotated on the surface of the transmission rod 602. The actuating plate 604 can rotate the movable gear ring 603 in the opposite direction and disengage from the fixed gear ring 606, thus avoiding interference.

[0024] A pressure rod 608 is movably set in the middle of the U-shaped drive plate 607, and the upper part of the pressure rod 608 is fixedly connected to the upper clamping end of the movable clamp 3. A limiting toothed plate 609 that cooperates with the limiting ring frame 601 is slidably provided on the side wall of the movable clamp 3. An L-shaped rocker plate 610 that cooperates with the pressure rod 608 is hinged to the side wall of the limiting toothed plate 609. The fulcrum of the L-shaped rocker plate 610 is rotatably connected to the side wall of the movable clamp 3. It should be noted that: a U-shaped hinge block is fixedly connected to the side wall of the limiting tooth plate 609, and a hinge rod is fixedly connected inside the U-shaped hinge block. The lower part of the L-shaped rocker 610 is provided with a hinge groove, and the lower part of the L-shaped rocker 610 is hinged to the surface of the hinge rod through the hinge groove. When the upper clamping end of the moving clamp 3 rises and releases the clamping of the copper-clad aluminum alloy conductor, the pressure rod 608 rises and drives the L-shaped rocker 610 to deflect, so that the L-shaped rocker 610 carries the hinged limiting tooth plate 609 to move horizontally at the side wall position of the moving clamp 3. The limiting tooth plate 609 is released from the engagement with the side wall of the limiting ring frame 601, so that the limiting ring frame 601 can move back to its original position with the moving baffle 5. The moving baffle 5 can be made of lightweight materials such as aluminum alloy.

[0025] In this embodiment, as Figures 1 to 13 As shown, a return spring is fixedly connected between the side wall of the limiting ring frame 601 and the side wall of the moving clamp 3, and the return spring is movably sleeved on the moving end of the corresponding hydraulic cylinder 4.

[0026] The side wall of the limiting ring frame 601 is fixedly connected with a limiting tooth block that mates with the limiting tooth plate 609. The side wall of the movable clamp 3 is provided with a guide groove, and the end of the limiting tooth plate 609 is slidably disposed inside the guide groove. It should be noted that the teeth of the limiting tooth plate 609 and the teeth of the limiting tooth block are wedge-shaped. When the limiting ring frame 601 slides at the movable end of the hydraulic cylinder 4, the limiting tooth plate 609 can unidirectionally limit the limiting teeth on the limiting ring frame 601. During the clamping process of the movable clamp 3 on the copper-clad aluminum alloy conductor, after the positioning calibration mechanism 6 drives the movable baffle 5 to move towards the end position of the copper-clad aluminum alloy conductor, the movable baffle 5 can be stably restricted at the current position to ensure the accuracy of subsequent monitoring of clamp slippage.

[0027] The fulcrum of the L-shaped rocker 610 is fixedly connected to a shaft. The end of the shaft is rotatably connected to the side wall of the movable clamp 3. A torsion spring is movably sleeved on the surface of the shaft, and the torsion spring is fixedly connected between the surfaces of the L-shaped rocker 610 and the movable clamp 3. It should be noted that when the movable clamp 3 moves down with the pressure rod 608, the pressure rod 608 no longer drives the L-shaped rocker 610 to deflect. At this time, the torsion spring causes the L-shaped rocker 610 to reset and flip. The L-shaped rocker 610 then moves the limiting toothed plate 609 to the side wall position of the corresponding limiting ring frame 601, thereby unidirectionally limiting the moving limiting ring frame 601.

[0028] In this embodiment, as Figures 1 to 13 As shown, the upper part of the actuating plate 604 has a waist-shaped groove, and the upper part of the actuating plate 604 is slidably mounted on the surface of the limiting ring frame 601 through the waist-shaped groove. It should be noted that when the transmission rod 602 rotates with the fixed gear ring 606 and the moving gear ring 603, the moving gear ring 603 causes the actuating plate 604 to deflect, and the actuating plate 604 slides with the limiting ring frame 601 at the movable end of the hydraulic cylinder 4 through the waist-shaped groove.

[0029] In this embodiment, as Figures 1 to 13 As shown, a connecting block is fixedly connected to the top of the pressure rod 608, and the pressure rod 608 is fixedly connected to the upper clamping end of the movable clamp 3 through the connecting block. A pad block that mates with the L-shaped rocker 610 is fixedly connected to the middle of the pressure rod 608. It should be noted that during the upward movement of the pressure rod 608, the L-shaped rocker 610 is deflected by the pad block.

[0030] The surface of the U-shaped drive plate 607 has a drive groove, and the lower part of the pressure rod 608 is fixedly connected to a drive pin. The drive pin is slidably disposed inside the corresponding drive groove. A one-way bearing is fixedly connected between the inner ring of the U-shaped drive plate 607 and the surface of the transmission rod 602. It should be noted that: when the pressure rod 608 moves down and engages with the U-shaped drive plate 607, the U-shaped drive plate 607 drives the transmission rod 602 to rotate synchronously through the one-way bearing. When the pressure rod 608 rises, the U-shaped drive plate 607 cannot drive the transmission rod 602 to rotate in the opposite direction through the one-way bearing. The deflection distance of the drive groove of the U-shaped drive plate 607 about the axis of the transmission rod 602 is set to 1.5 times the downward movement distance of the pressure rod 608 carried by the moving clamp 3, ensuring that the U-shaped drive plate 607 can be effectively driven to rotate through the pressure rod 608 during the downward movement of the moving clamp 3 to clamp the copper-clad aluminum alloy conductor.

[0031] A connecting plate is rotatably connected to the end of the transmission rod 602 away from the U-shaped drive plate 607, and the connecting plate is fixedly connected to the side wall of the moving clamp 3. It should be noted that a support bearing is fixedly connected between the surface of the transmission rod 602 and the surface of the connecting plate; a compression spring 605 is disposed between the side wall of the connecting plate and the side wall of the moving gear ring 603.

[0032] In this embodiment, as Figures 1 to 13As shown, the displacement monitoring mechanism 7 includes: a monitoring cylinder 701 fixedly connected to the side wall of the moving baffle 5; a pointer rod 702 rotatably connected to the middle of the monitoring cylinder 701; an adjusting plate 703 fixedly sleeved at the middle of the pointer rod 702; a linkage rod 704 hinged to the surface of the adjusting plate 703; a detection plate 705 fixedly connected to one end of the linkage rod 704 through the monitoring cylinder 701; and a return spring 706 fixedly connected between the side wall of the detection plate 705 and the inner wall of the moving baffle 5. It should be noted that when the moving baffle 5 is driven to the end of the copper-clad aluminum alloy conductor by the positioning and calibration mechanism 6 and comes into contact with it, the detection plates 705 on the moving baffle 5 and the fixed baffle 8 respectively overlap with both ends of the copper-clad aluminum alloy conductor. Both detection plates 705 are in the calibrated position, and the pointer rod 702 is at the zero point. During the stretching process of the copper-clad aluminum alloy conductor, if the fixed clamp 2 or the moving clamp 3 slips, the detection plate 705 at the corresponding position will move relative to the end of the copper-clad aluminum alloy conductor. At this time, the return spring 706 will drive... The moving detection plate 705 is attached to the end of the copper-clad aluminum alloy conductor, causing the moving detection plate 705 to move along with the linkage rod 704. The linkage rod 704, in conjunction with the adjusting plate 703, drives the pointer rod 702 to rotate inside the monitoring cylinder 701, thereby measuring the offset of the slippage position and facilitating the subsequent supplementation of the slippage stretching amount. The front end of the monitoring cylinder 701 is provided with a scale line that cooperates with the pointer rod 702. The stretching error of the copper-clad aluminum alloy conductor is within 5% and is considered a qualified product. If it exceeds 5%, the slippage stretching amount needs to be supplemented.

[0033] A warning light tube 707 is fixedly connected to the top of the monitoring tube 701. A trigger rod 708 is slidably mounted on the lower part of the warning light tube 707. One end of the pointer rod 702 is fixedly connected to a protrusion 709 that mates with the trigger rod 708. It should be noted that when the pointer rod 702 rotates, it will cause the protrusion 709 to contact the trigger rod 708, thus engaging the trigger rod 708 with the warning light tube 707.

[0034] In this embodiment, as Figures 1 to 13 As shown, a storage groove that cooperates with the detection plate 705 is provided on the left side of the moving baffle 5. Guide grooves are symmetrically provided on the surface of the moving baffle 5. A guide rod is slidably arranged inside the guide groove. One end of the guide rod is fixedly connected to the side wall of the detection plate 705. The inner wall of the receiving slot has an insertion hole that mates with the monitoring cylinder 701. The linkage rod 704 is movably inserted into the insertion hole. The surface of the adjusting plate 703 has a linkage groove. The end of the linkage rod 704 is fixedly connected to a linkage pin, which is slidably disposed inside the linkage groove. It should be noted that when the linkage rod 704 moves with the detection plate 705, the linkage rod 704 drives the adjusting plate 703 and the pointer rod 702 to rotate inside the monitoring cylinder 701 through the linkage pin and the linkage groove. When the detection plate 705 is in contact with the end of the copper-clad aluminum alloy conductor, the detection plate 705 is inside the receiving slot, and the side wall of the detection plate 705 translates with the side wall of the moving baffle 5. In this state, the pointer rod 702 is at the zero position.

[0035] In this embodiment, as Figures 1 to 13 As shown, a trigger metal piece is fixedly connected to the upper part of the inner wall of the warning light tube 707. The trigger rod 708 is coaxially arranged with the trigger metal piece, and a return spring is movably sleeved on the lower part of the trigger rod 708. It should be noted that when the pointer rod 702 rotates with the protrusion 709, the protrusion 709 presses the trigger rod 708 and rises inside the warning light tube 707, contacting the trigger metal piece. After the trigger metal piece is pressed, the warning light tube 707 is energized, and the warning light at the top of the warning light tube 707 lights up to indicate the work. This pressure-triggered warning light tube 707 is existing technology and will not be described in detail here.

[0036] In this embodiment, as Figures 1 to 13 As shown, a method for using a stretching device for producing copper-clad aluminum alloy conductors includes the following steps: S1. When in use, place the copper-clad aluminum alloy conductor on the surface of the guide roller at the top of the tension bracket 1, with the left end of the copper-clad aluminum alloy conductor overlapping the side wall of the fixed baffle 8, and then start the fixed clamp 2 and the moving clamp 3 to clamp the copper-clad aluminum alloy conductor.

[0037] S2. During the process of the upper clamping end of the movable clamp 3 moving down to clamp the right end of the copper-clad aluminum alloy conductor, the pressure rod 608 moves down synchronously with the upper clamping end of the movable clamp 3 through the connecting block. At this time, the lower part of the pressure rod 608 slides through the drive pin and the drive groove on the surface of the U-shaped drive plate 607, so that the U-shaped drive plate 607 carries the transmission rod 602 to rotate on the side wall of the connecting plate. Since the movable toothed ring 603 is pressed and attached to the surface of the fixed toothed ring 606 by the compression spring 605 and meshes with it, when the transmission rod 602 rotates, it will carry the fixed toothed ring 606 and the movable toothed ring 603 to rotate synchronously, so that the movable toothed ring 603 carries the actuating plate 604 to rotate synchronously. The actuating plate 604 then cooperates with the limiting ring frame 601 through the waist-shaped groove, so that the limiting ring frame 601 slides at the movable end of the hydraulic cylinder 4. The two limiting ring frames 601 carry the movable baffle 5 to be attached to the right end of the copper-clad aluminum alloy conductor.

[0038] S3. When the right end of the copper-clad aluminum alloy conductor is pressed by the moving baffle 5, the left end of the copper-clad aluminum alloy conductor is tightly attached to the right side of the fixed baffle 8. The position of the copper-clad aluminum alloy conductor before clamping is calibrated to ensure clamping stability. As the upper clamping end of the moving clamp 3 continues to move down, the copper-clad aluminum alloy conductor after calibration is clamped. When the moving baffle 5 can no longer move after pressing the right end of the copper-clad aluminum alloy conductor, the actuating plate 604 and the moving gear ring 603 can no longer rotate. At this time, the transmission rod 602 will drive the compression spring 605 on the side wall of the moving gear ring 603 to compress during the rotation of the fixed gear ring 606, so as to avoid interference.

[0039] S4. When the moving baffle 5 and the fixed baffle 8 are in contact with the end of the copper-clad aluminum alloy conductor on the opposite side, the detection plate 705 on the side wall of the moving baffle 5 and the fixed baffle 8 is in close contact with the end of the copper-clad aluminum alloy conductor. During this process, the pressurized detection plate 705 moves the linkage rod 704 towards the inside of the monitoring cylinder 701, so that the linkage rod 704 slides through the linkage pin and the linkage groove on the surface of the adjusting plate 703, thereby driving the adjusting plate 703 and the pointer rod 702 to rotate to the zero position inside the monitoring cylinder 701.

[0040] S5. Then, the hydraulic cylinder 4 is activated to move the movable clamp 3, stretching the clamped copper-clad aluminum alloy conductor. If slippage occurs during the stretching process of the movable clamp 3 or the fixed clamp 2, the copper-clad aluminum alloy conductor will displace between itself and the fixed clamp 2 or the movable clamp 3. The displaced end of the copper-clad aluminum alloy conductor will no longer be tightly fitted to the side wall of the movable baffle 5 or the fixed baffle 8. At this time, under the elastic recovery action of the return spring 706, the detection plate 705 in the middle of the movable baffle 5 or the fixed baffle 8 can extend from the corresponding receiving slot and continue to be fitted to the end of the copper-clad aluminum alloy conductor. During the movement of the detection plate 705, the linkage rod 704 moves synchronously, causing the linkage rod 704 to slide in conjunction with the adjustment plate 703 and drive the pointer rod 702 to rotate inside the monitoring cylinder 701. The rotating pointer rod 702 displays the specific amount of slippage according to the scale lines. At the same time, the protrusion 709 rotates synchronously with the pointer rod 702 and presses against the trigger rod 708 and the warning light 707 to alert the operator. The displayed amount of slippage makes it easy for the operator to pull back the slipped stretching amount later, ensuring the length and quality of the copper-clad aluminum alloy conductor stretching production.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

A method of using a stretching device for producing copper-clad aluminum alloy conductors, characterized in that, Using the stretching equipment for producing copper-clad aluminum alloy conductors as described in any one of claims 1-8, the process includes the following steps: S1. Clamping calibration: Place the copper-clad aluminum alloy conductor on the guide roller of the tension bracket (1), with the left end attached to the fixed baffle (8). Start the fixed clamp (2) and the moving clamp (3) to clamp. When the moving clamp (3) moves down to clamp, it drives the limit ring frame (601) and the moving baffle (5) to move through the pressure rod (608), U-shaped drive plate (607) and other components, and attaches to the right end of the copper-clad aluminum alloy conductor, so that the left end of the conductor is close to the fixed baffle (8) to complete the position calibration. After calibration, the moving clamp (3) continues to clamp. If the moving baffle (5) cannot move, the transmission rod (602) will drive the compression spring (605) on the side wall of the moving gear ring (603) to compress during the rotation of the fixed gear ring (606) to avoid interference. S2, Zero point positioning: When the end of the copper-clad aluminum alloy conductor is in contact with the moving baffle (5) and the fixed baffle (8), the pressurized detection plate (705) drives the linkage rod (704) to move, and the pointer rod (702) is rotated to zero point in the monitoring cylinder (701) by the adjustment plate (703); S3. Stretching and slippage monitoring: Start the hydraulic cylinder (4) to drive the moving clamp (3) to stretch the copper-clad aluminum alloy conductor. If the fixed clamp (2) or the moving clamp (3) slips during stretching, the copper-clad aluminum alloy conductor will be displaced from the fixed clamp (2) or the moving clamp (3), and its end will be separated from the moving baffle (5) or the fixed baffle (8). The return spring (706) will push the detection plate (705) to extend and re-attach to the copper-clad aluminum alloy conductor. At the same time, it will drive the linkage rod (704) to rotate the pointer rod (702) to display the amount of slippage. The protrusion (709) and the trigger rod (708) will trigger the warning light (707) to remind the operator. S4. Slippage Treatment: Operators can adjust the stretching amount based on the displayed slippage amount to ensure the stretching length and quality of the copper-clad aluminum alloy conductor.
