Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, specifically to a transformer coil wire joint crimping device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] When existing transformers are manufactured in the factory, they typically undergo multiple processing steps, with each component requiring unique machining operations. Before installation, the coil wires inside the transformer need to have their ends connected to connectors to facilitate subsequent connections to external wiring. Current crimping methods, often done manually, can accomplish this task, but they have significant drawbacks in practical use, such as: In addition to being round, the conductors inside the transformer are also flat, but the connectors are round. Therefore, to install the flat copper wires with the connectors, the two sides of the flat copper wire ends need to be pressed down to make them arc-shaped before inserting the connectors and crimping them again. These two steps are done manually, which is too tedious and complicated. Moreover, it requires the staff to constantly judge the crimping, which is not only inefficient but also easy to cause visual fatigue. Therefore, a transformer coil wire joint crimping device that can improve crimping efficiency has been designed to address this type of defect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a transformer coil wire joint crimping device, which solves the problems of low efficiency and cumbersome crimping of existing wire joints.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer coil wire connector crimping device, comprising a processing platform, a motor fixedly connected to the bottom of the processing platform via a bracket, a rotating rod fixedly connected to the output shaft of the motor via a coupling, the top end of the rotating rod penetrating the processing platform and extending to the upper part of the processing platform, a conical base plate fixedly connected to the upper end of the rotating rod via a fixing block, and a rectangular spring frame fixedly connected to the top of the conical base plate via a fixing plate.

[0006] Preferably, the top of the rectangular spring frame is fixedly connected to an L-shaped concave frame via a fixing plate. A rectangular guide groove is provided on the left side of the L-shaped concave frame. An L-shaped guide plate is slidably installed on the inner side of the rectangular guide groove, and the bottom end of the L-shaped guide plate extends to the inner side of the rectangular spring frame. A sealing plate that cooperates with the L-shaped concave frame is fixedly connected to the top of the L-shaped guide plate, and a rectangular pressure block is fixedly connected to the bottom of the sealing plate.

[0007] Preferably, a rebound rod is fixedly connected to the top of the inner cavity of the rectangular spring frame by a fixing block, and the bottom end of the rebound rod passes through the L-shaped guide plate and extends to the bottom of the L-shaped guide plate. The L-shaped guide plate is slidably connected to the rebound rod, and a first spring is sleeved on the surface of the rebound rod between the L-shaped guide plate and the rectangular spring frame.

[0008] Preferably, the front and rear parts of the rectangular spring frame are fixedly connected to a curved rod by a fixing block, the end of the curved rod away from the rectangular spring frame is fixedly connected to a curved expansion plate by a fixing block, and both sides of the top of the curved expansion plate are fixedly connected to a U-shaped blocking frame by a fixing block.

[0009] Preferably, a horizontal sliding rod is slidably installed on the opposite sides of the inner sides of the two U-shaped blocking frames through openings. An arc-shaped clamping frame is fixedly connected to the opposite ends of the two horizontal sliding rods through a fixing block. A pressure-bearing concave plate is fixedly connected to the opposite ends of the two horizontal sliding rods through a fixing block. A second spring is sleeved on the surface of the horizontal sliding rod and located between the U-shaped blocking frame and the pressure-bearing concave plate.

[0010] Preferably, the top of the processing platform is fixedly installed with an upper support plate by a bracket, and an electric telescopic rod is fixedly connected to the top of the upper support plate by an opening. The bottom end of the electric telescopic rod is fixedly connected to a horizontal pressure plate that works with the lifting rod by a fixing block. The front end and the rear end of the horizontal pressure plate are respectively fixedly connected to a first pressing machine and a second pressing machine by fixing blocks.

[0011] Preferably, the rear parts of both sides of the horizontal pressure plate are fixedly connected to inclined pressure plates that cooperate with the pressure-bearing concave plate by brackets, and the inclined pressure plates are located at the lower part of the second pressing machine.

[0012] Preferably, a lifting rod is fixedly connected to the top of the sealing plate by a fixing block.

[0013] This invention provides a crimping device for transformer coil conductor joints. Compared with existing technologies, it has the following advantages: (1) The transformer coil wire joint crimping device is equipped with a first crimping machine and a second crimping machine on the top of the processing platform, and is used in conjunction with an arc-shaped clamping frame and a sloping pressure plate. When several copper wires are stacked and placed inside the L-shaped concave frame, the second crimping machine and the first crimping machine can be used to pre-roll both ends of the copper wires at the same time, so that both ends are arc-shaped. Then the joint is sleeved with one end, and the second crimping machine is used to crimp. After that, the motor is started and the position is adjusted to crimp the other end. The whole process does not require the operator to perform too much operation. It is only necessary to sleeve the joint, which effectively improves the crimping efficiency.

[0014] (2) The transformer coil wire joint crimping device is equipped with an arc-shaped clamping frame and a pressure-bearing concave plate at the front and rear of the rectangular spring frame, and is used in conjunction with an inclined pressure plate. The arrangement of these structures allows the inclined pressure plate to be inserted into the inner side of the pressure-bearing concave plate by the descent of the electric telescopic rod before the second crimping machine crimps the joint. This pushes the two arc-shaped clamping frames to move towards each other to wrap and clamp the joint, thereby ensuring that the joint crimping is more stable and improving the crimping quality.

[0019] Furthermore, an L-shaped recessed frame 6 is fixedly connected to the top of the rectangular spring frame 5 via a fixing plate. A rectangular guide groove 7 is provided on the left side of the L-shaped recessed frame 6. An L-shaped guide plate 8 is slidably installed on the inner side of the rectangular guide groove 7, and the bottom end of the L-shaped guide plate 8 extends to the inner side of the rectangular spring frame 5. A sealing plate 11 that cooperates with the L-shaped recessed frame 6 is fixedly connected to the top of the L-shaped guide plate 8. A rectangular pressure block 12 is fixedly connected to the bottom of the sealing plate 11. The top of the inner cavity of the rectangular spring frame 5 is fixedly connected to a spring rod 9 by a fixing block, and the bottom end of the spring rod 9 passes through the L-shaped guide plate 8 and extends to the bottom of the L-shaped guide plate 8. The L-shaped guide plate 8 is slidably connected to the spring rod 9. A first spring 10 is sleeved on the surface of the spring rod 9 and between the L-shaped guide plate 8 and the rectangular spring frame 5. The front and rear parts of the rectangular spring frame 5 are fixedly connected to a bent rod 14 by a fixing block. The end of the bent rod 14 away from the rectangular spring frame 5 is fixedly connected to a bent expansion plate 26 by a fixing block. Both sides of the top of the bent expansion plate 26 are fixedly connected to a U-shaped stop frame 15 by a fixing block.

[0020] Among them, the two U-shaped blocking frames 15 have a horizontal sliding rod 16 slidably installed on the opposite side of their inner sides through openings. The opposite ends of the two horizontal sliding rods 16 are fixedly connected to an arc-shaped clamping frame 17 through a fixing block. The opposite ends of the two horizontal sliding rods 16 are fixedly connected to a pressure-bearing concave plate 18 through a fixing block. A second spring 19 is sleeved on the surface of the horizontal sliding rod 16 and located between the U-shaped blocking frame 15 and the pressure-bearing concave plate 18. The top of the processing platform 1 is fixedly installed with an upper support plate 20 by a bracket. The top of the upper support plate 20 is fixedly connected with an electric telescopic rod 21 through an opening. The bottom end of the electric telescopic rod 21 is fixedly connected with a horizontal pressure plate 22 that works with the lifting rod 13 by a fixing block. The front and rear ends of the horizontal pressure plate 22 are fixedly connected with a first pressing machine 23 and a second pressing machine 24 by fixing blocks, respectively. The rear parts of both sides of the horizontal pressure plate 22 are fixedly connected with inclined pressure plates 25 that work with the pressure-bearing concave plate 18 by brackets. The inclined pressure plates 25 are located below the second pressing machine 24. The top of the sealing plate 11 is fixedly connected with the lifting rod 13 by a fixing block.

[0021] In use, first pull the lifting rod 13 to lift the sealing plate 11, separating it from the L-shaped recessed frame 6. Then, place the flat copper wires stacked inside the L-shaped recessed frame 6. After placement, release the rod to allow the sealing plate 11 to re-close with the L-shaped recessed frame 6 using the elastic force of the first spring 10, thus limiting the copper wires. Then, the operator manually presses the front and rear ends of the copper wires to align them. Subsequently, the electric telescopic rod 21 is activated to push the horizontal pressure plate 22, which in turn drives the first pressing machine 23 and the second pressing machine 24. The clamping machine 24 descends synchronously. When the horizontal pressure plate 22 reaches the bottom, it presses against the top of the lifting rod 13. At this time, the lifting rod 13 is again limited to fix several copper wires. Both the first clamping machine 23 and the second clamping machine 24 clamp the two ends of the copper wires. Then, the first clamping machine 23 and the second clamping machine 24 are activated to squeeze the end faces of the copper wires, thereby clamping the sides of the two ends of the copper wires into an arc shape. Then, the electric telescopic rod 21 is activated again to drive the first clamping machine 23 and the second clamping machine 24 to rise, and then the connector is put on the copper wire. At the rear end of the line, the electric telescopic rod 21 is then activated to push the horizontal pressure plate 22 down. The descent of the horizontal pressure plate 22 utilizes the inclined pressure plate 25 to first insert into the inner side of the rear bearing concave plate 18. Then, guided by the horizontal sliding rod 16, it pushes the two arc-shaped clamping frames 17 to move towards each other, clamping the joint. The continuous descent of the second clamping machine 24 then covers the joint. The second clamping machine 24 then activates to clamp the joint, completing the installation. After the installation of one end of the joint is completed, the electric telescopic rod 21 is activated to connect the first clamping machine 23 with the second clamping machine. The machine 24 is raised, and then the motor 2 is started. The rotating rod 3 drives the conical base plate 4 and the rectangular spring frame 5 to rotate, so that the end without the connector is turned to the rear. Then the connector is put on the other end of the copper wire, and the electric telescopic rod 21 is started again to drive the first crimping machine 23 and the second crimping machine 24 to descend. Then the second crimping machine 24 crimps the connector again. At this time, the connector of the wire is crimped. The worker pulls the lifting rod 13 again to separate the sealing plate 11 from the L-shaped concave frame 6, and then takes out the crimped copper wire.
