Description
Technical Field
[0001] This utility model relates to the field of bending component technology, specifically a secondary bending component for processing the inner conductor of an RF connector. Background Technology
[0002] Secondary bending components in the inner conductor processing of RF connectors refer to structural components that undergo two or more bending processes during the inner conductor manufacturing process. These components are typically used to achieve specific spatial layout and electrical connection requirements of the inner conductor within the connector, such as adjusting the signal transmission path within a limited space or meeting specific mechanical installation requirements. The processing precision requirements for secondary bending components are extremely high, ensuring that good conductivity and signal integrity are maintained after multiple bends, while avoiding mechanical deformation or stress concentration caused by bending, thereby ensuring the overall performance and reliability of the RF connector. The inner conductor of an RF connector is a key component, usually located at the center of the connector, and is used to transmit high-frequency signals. It is generally made of a metal material with excellent conductivity to ensure low signal loss and high efficiency in signal transmission. The shape and size of the inner conductor are designed according to the specific model of the connector and the application scenario. Its surface is usually finely processed to reduce signal reflection and standing wave effects, thereby ensuring signal integrity and stability. In the processing of the inner conductor of an RF connector, the second bending operation of the secondary bending assembly faces significant spatial distribution challenges. During the first bending, the inner conductor can be precisely positioned and stabilized with the help of a specialized fixing structure, thereby ensuring that the direction and position of the bent part strictly meet the design requirements. However, after the second bending, due to the change in bending direction, it is difficult to maintain the other end of the inner conductor in the predetermined position using traditional fixing methods. This makes the inner conductor prone to positional deviation after bending, thus affecting the bending quality. Therefore, a secondary bending assembly for processing the inner conductor of an RF connector is proposed to address the above problems. Utility Model Content

Through the above settings, this design ensures the overall structural stability of the device and can accurately control the position and spacing of the inner conductor during the bending process, thereby improving the bending accuracy and quality. As a further implementation of this solution, the adjustment component 5 includes a servo motor 51. The housing of the servo motor 51 is fixedly connected to the rear end of the upright plate 52. A through hole is opened in the middle of the upright plate 52, and an annular groove 53 is opened outside the through hole. The bottom end of the servo motor 51 is fixedly connected to the top end of the worktable 1. An annular shell 54 is fixedly connected to the end of the spindle of the servo motor 51. The annular shell 54 is hollow near the rear end. A rotating column is fixedly connected to the axis of the annular shell 54. The rotating column of the annular shell 54 is rotatably connected inside the through hole of the upright plate 52. The rear end of the annular shell 54 rotates inside the annular groove 53. A single beam dual-drive linear motor 55 is fixedly connected to the front end of the annular shell 54. The front end of the single beam dual-drive linear motor 55 is fixedly connected to the rear end of the horizontal plate 61. Through the above settings, stable power transmission and precise motion control are provided, and the rotation angle of the inner conductor can be precisely controlled during the bending process to meet the needs of bending various shapes. As a further implementation of this solution, one end of the spring telescopic rod 65 is fixedly connected to the movable block 67, and the two spring telescopic rods 65 are distributed at the left and right ends of the movable block 67. The movable block 67 is embedded in the interior groove 63, and a shaft hole is opened on the inner side of the movable block 67. The end of the pressure plate 66 near the pressure roller 69 has an arc-shaped structure, and the front and rear ends of the pressure roller 69 are fixedly connected to bearings. Through the above settings, it is ensured that the inner conductor can be kept in the predetermined position during the bending process, thereby improving the bending accuracy and quality.
[0018] Workflow: When performing a secondary bending of the inner conductor of the RF connector, the inner conductor is passed between two pressure rollers 69. After the inner conductor contacts the pressure rollers 69, it is squeezed, and the pressure rollers 69 move inward toward the inner groove 63. The pressure rollers 69 drive the movable block 67 to move, and the movable block 67 squeezes the spring telescopic rod 65. Through the elastic force of the spring telescopic rod 65, the two pressure rollers 69 can simultaneously clamp the inner conductor. As the inner conductor moves, friction drives the pressure rollers 69 to rotate. The pressure rollers 69 rotate inside the movable block 67. The device features a dynamic setting for easy adjustment of the distance between the two ends of the inner conductor and the pressure roller 69. Based on the size of the inner conductor, the distance between the inner conductor and the pressure rollers 69 at the left and right ends needs to be controlled. By controlling the single-beam dual-drive linear motor 55, the two sets of positioning components 6 are moved, thereby controlling the required bending distance of the inner conductor and improving the practicality of the device. After the bending position is adjusted, the electric telescopic rod 64 is activated to move the pressure plate 66 towards the pressure roller 69, causing the pressure plate 66 to fit against the outer side of the pressure roller 69. Through friction, the pressure roller 69 is prevented from rotating, thus controlling the stability of the bending of the inner conductor. Qualitatively, by controlling the electric hydraulic rod 3 to push the punch plate 4 downward, one end of the inner conductor is first bent. The distribution of the pressure roller 69 and the outer shell 62 provides bending space for the inner conductor, preventing breakage due to a small chamfer. Then, by controlling the position of the two positioning components 6 through the single-beam dual-drive linear motor 55, the inner conductor is bent a second time. The shape formed by this bending is U-shaped. When a Z-shape is required, after bending one side of the inner conductor, the servo motor 51 is started to drive the ring shell 54 to rotate. The design of the ring shell 54 embedded inside the vertical plate 52 plays a role in bending. The device bears weight during bending. After the inner conductor rotates 180 degrees, the other end of the inner conductor is bent, thus achieving various bending shapes and further improving the performance of the device. Based on the above principles, when the device performs a secondary bend on the inner conductor of the RF connector, it first positions the two ends of the inner conductor that need to be bent before bending. This bending method avoids the difficulty of maintaining the predetermined position due to multiple positioning, reduces the possibility of positional deviation of the inner conductor after bending, and thus ensures the bending quality. At the same time, it can be changed according to the shape of the inner conductor bend, improving the convenience of the device.
