Technical Field

[0001] This utility model relates to the field of straightening and stamping devices, and in particular to a novel straightening and stamping device for press tubes. Background Technology

[0002] Crimped connectors (also known as conductor connectors or splice pipes) are core hardware used for conductor connections in power and communication engineering. They achieve reliable conductor connections through mechanical or hydraulic means and are made of metal materials.

[0003] Utility model patent CN219966273U discloses a novel straightening and stamping device for press-fit tubes, including a bracket. A first die-cutting head and a second die-cutting head are mounted on the bracket. The second die-cutting head is slidably connected to the bracket. A first stamping groove is provided on the side of the first die-cutting head closest to the second die-cutting head, and a second stamping groove adapted to the first stamping groove is provided on the side of the second die-cutting head closest to the first stamping groove. A stamping hole is formed between the first and second stamping grooves, allowing the press-fit tube to pass through. A driving device is connected to the side of the second die-cutting head furthest from the first die-cutting head. This driving device drives the second die-cutting head to slide on the bracket. The press-fit tube to be straightened is passed through the first stamping groove, and the driving device is activated. The driving device moves the second stamping groove towards the press-fit tube. Under the action of the driving device, the first stamping groove and the second stamping groove stamp the press-fit tube, achieving one-time straightening and forming. The operation is simple and the effect is good.

[0004] When the straightening stamping device of this structure is in use, the protrusion can extend into the straight section and slide within the straight section. The radius of the first stamping groove is larger than the radius of the second stamping groove. When the size of the first stamping groove is adapted to the pressure tube, the size of the second stamping groove is smaller than the pressure tube. When the size of the second stamping groove is adapted to the pressure tube, the size of the first stamping groove is slightly larger than the pressure tube, thus affecting the straightening stamping effect of the pressure tube.

[0005] Therefore, it is necessary to provide a new type of press tube straightening and stamping device to solve the above-mentioned technical problems. Utility Model Content

[0019] In the specific implementation process, such as Figures 1-4As shown, the device includes a mounting frame 1. A first semi-circular plate 2 is fixed to one side of the mounting frame 1, and a second semi-circular plate 3 is provided on the other side of the mounting frame 1. The first semi-circular plate 2 and the second semi-circular plate 3 are arranged opposite each other and have the same radius. The second semi-circular plate 3 can move laterally on the mounting frame 1. Extension frames 4 are installed laterally at both ends of the top and bottom of the first semi-circular plate 2. One end of the extension frame 4 is fixed to the first semi-circular plate 2, and the other end of the extension frame 4 is slidably disposed on the second semi-circular plate 3. The vertical distance between the center line of the first semi-circular plate 2 and the extension frame 4 is equal to the radius of the first semi-circular plate 2. A driving device is also installed on the mounting frame 1 to drive the second semi-circular plate 3. The plate 3 slides. During use, the pressure tube is placed between the first semi-arc plate 2 and the second semi-arc plate 3, and between the two extension frames 4 on the same side of the first semi-arc plate 2. The second semi-arc plate 3 is driven to move towards the first semi-arc plate 2 by the driving device to realize the straightening and stamping of the pressure tube. This application has horizontally arranged extension frames 4 installed at both ends of the top and bottom of the first semi-arc plate 2. The two extension frames 4 limit the pressure tube longitudinally. With this structure, the second semi-arc plate 3 can be set to have the same radius as the first semi-arc plate 2, so that it can better adapt to the straightening tube during the straightening and stamping and improve the straightening and stamping effect. An extension groove 6 is provided on the second semi-arc plate 3. The end of the extension frame 4 away from the first semi-arc plate 2 is slidably disposed in the extension groove 6. A rod 7 is fixed in the extension groove 6. The rod 7 moves through the extension frame 4. Through the rod 7 and the extension groove 6, when the second semi-arc plate 3 moves toward the first semi-arc plate 2, the end of the extension frame 4 moves in the extension groove 6. The driving device includes an electric cylinder 8 and a power supply device 9. Both the power supply device 9 and the electric cylinder 8 are fixed on the mounting bracket 1. The power supply device 9 is electrically connected to the electric cylinder 8. The telescopic end of the electric cylinder 8 is fixed on the second semi-arc plate 3. The power supply device 9 supplies power to the electric cylinder 8, causing the electric cylinder 8 to drive the second semi-arc plate 3 to move towards the first semi-arc plate 2. The power supply device 9 in this application includes a power source and a driver. In use, the output end of the power source is connected to the power input terminal of the driver using a cable. At the same time, the driver needs to be connected to the motor interface of the electric cylinder 8, and the control signal end is connected to the upper controller (such as a PLC or a manual control box). After being turned on, the power source provides electrical energy, and the driver is responsible for controlling the power output to drive the electric cylinder 8 to perform linear motion. In addition, the driving device in this application can also be the driving device provided in the utility model with publication number CN219966273U. Guide blocks 10 are fixed on both sides of the second semi-arc plate 3. The guide blocks 10 are slidably disposed in the guide groove 21 opened in the mounting frame 1. When the second semi-arc plate 3 moves, the guide blocks 10 move in the guide groove 21 to improve the stability of the second semi-arc plate 3 when it moves. The second semi-arc plate 3 has a placement groove 11 on its arc surface. A pressing plate 12 of appropriate size is provided in the placement groove 11. At least two connecting rods 13 are fixed on the pressing plate 12. The connecting rods 13 move through the bottom wall of the placement groove 11. The ends of the at least two connecting rods 13 are fixed to a bearing plate 14. A bearing frame 15 is also fixed on the second semi-arc plate 3. A spring 16 is fixed on the bearing plate 14. One end of the spring 16 is installed on the bearing frame 15 through an adjusting component. When the pressing tube is placed, the bearing plate 14 can be pulled. After the pressing tube is placed, the spring 16 is in a compressed state, thereby providing a certain force to the pressing tube through the pressing plate 12 and reducing the possible shaking of the pressing tube. The adjusting component includes a threaded rod 17, an adjusting plate 18, and a throttle 19. The threaded rod 17 is threadedly connected to the support frame 15. One end of the threaded rod 17 is fixed to the throttle 19, and the other end of the threaded rod 17 is rotatably connected to the adjusting plate 18. The adjusting plate 18 is fixedly connected to the spring 16. Rotating the throttle 19 causes the threaded rod 17 to rotate, which in turn moves the adjusting plate 18. This allows the spring force of the spring 16 to change when the pressing plate 12 is in the same position. For example, when the pressing force of the pressing plate 12 on the pressing tube is small, the threaded rod 17 can be rotated to increase the force on the pressing tube. Both ends of the adjusting plate 18 are fixed with protruding plates 20. The two protruding plates 20 are slidably disposed in the protruding grooves 5 opened on opposite sides of the bearing frame 15. Through the protruding plates 20, the adjusting plate 18 can move stably when the threaded rod 17 rotates.
