Description
Technical Field
[0001] This utility model belongs to the field of connector pin processing technology, specifically, it relates to a connector pin bending assembly. Background Technology
[0002] As a core component in electronic devices that enables circuit connectivity, the bending accuracy of connector pins directly determines the assembly compatibility and electrical connection stability between the connector and the circuit board. Therefore, the pin bending process is a critical step in connector manufacturing, placing stringent requirements on the accuracy, efficiency, and batch consistency of bending equipment. With the electronics industry moving towards miniaturization and high density, connector pin dimensions are becoming increasingly precise, and traditional bending techniques are gradually failing to meet the high-precision demands of industrial production.
[0003] Existing automated equipment still has significant shortcomings in precision control and structural design: most equipment adopts a single-stage, one-time bending mode, which directly pushes the bending structure to bend the pin through the drive component. Due to the lack of a transitional preliminary shaping stage, the bending force is applied to the pin instantly, which can easily cause the pin to spring back elastically, resulting in a deviation between the actual bending angle and the preset angle.
[0004] In view of this, this utility model is hereby proposed. Utility Model Content
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A connector pin bending assembly, including a base.
[0006] A positioning frame is installed on the base, and a slot is provided on the positioning frame for engaging the connector. A bracket is installed on the base, a hydraulic push rod is installed on the bracket, a push block is installed at the output end of the hydraulic push rod, a pressure plate is rotatably installed on the side wall of the push block, the pressure plate is in an inclined state, and the pressure plate contacts the connector pin during the movement of the pressure plate, squeezing the connector pin and initially bending it; A push plate is installed at the rotation center of the pressure plate, and a top rod is slidably arranged on the push plate. The top rod is horizontally inserted into the push block. When the top rod is pressed against the side wall of the positioning frame, it drives the push plate to flip and drives the pressure plate to flip synchronously, so that the pins of the Shudie connector are folded into a vertical state.
[0007] In a preferred embodiment of the present invention, a base plate is provided at the bottom of the base. The base plate is in the shape of a boss and a protective pad is provided at the bottom of the base plate. An mounting plate is welded to the side wall of the base and the mounting plate is connected to the base plate by bolts.
[0008] In a preferred embodiment of this utility model, the push plate has a notch, the inner wall of the notch has a strip groove, the strip groove is in the shape of a straight line, the push rod is disposed inside the notch, and a sliding rod is installed on the side wall of the push rod, the sliding rod is slidably disposed on the strip groove.
[0009] In a preferred embodiment of this utility model, a flat plate is installed at one end of the top rod, the cross-sectional area of the flat plate is larger than the cross-sectional area of the top rod, and the flat plate corresponds to the end of the positioning frame.
[0010] In a preferred embodiment of this utility model, a limiting seat is movably inserted into the top rod, the limiting seat is installed inside the push block, and a limiting plate is installed at the other end of the top rod, the diameter of the limiting plate being larger than the diameter of the top rod.
[0011] In a preferred embodiment of this utility model, a baffle is installed on the side wall of the top rod, and a compression spring is sleeved on the top rod located between the baffle and the limiting seat. One end of the compression spring is engaged with the limiting seat, and the other end of the compression spring is engaged with the baffle.
[0012] Compared with the prior art, the present invention has the following advantages: This invention employs a step-by-step operation mode of initial bending and precise folding. Initially, the pressure plate, which is tilted, contacts the pin and applies uniform pressure to complete the initial shaping of the pin. As the pusher continues to move, the push rod contacts the positioning frame and is compressed. Through the cooperation of the slide rod and the strip groove, the pusher is driven to flip, which in turn drives the pressure plate to flip synchronously, precisely bending the pin to a vertical state. This structured transmission and guiding design effectively improves the consistency of bending angles in batch operations.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0017] like Figures 1 to 6 As shown, a connector pin bending assembly includes a base 1.
[0018] A positioning frame 4 is mounted on the base 1. The positioning frame 4 has a slot 5 for engaging the connector. A bracket 6 is mounted on the base 1. A hydraulic push rod 7 is mounted on the bracket 6. A push block 8 is mounted on the output end of the hydraulic push rod 7. A pressure plate 9 is rotatably mounted on the side wall of the push block 8. The pressure plate 9 is in an inclined state. During the movement of the pressure plate 9, it contacts the connector pins and compresses the connector pins to initially bend them. A push plate 10 is installed at the rotation center of the pressure plate 9. A push rod 13 is slidably arranged on the push plate 10, and the push rod 13 is horizontally inserted into the push block 8. When the push rod 13 is pressed against the side wall of the positioning frame 4, it drives the push plate 10 to flip and drives the pressure plate 9 to flip synchronously, so that the connector pins are folded into a vertical state.
[0019] like Figures 1 to 6 As shown in the specific embodiment, a base plate 2 is provided at the bottom of the base 1. The base plate 2 is in the shape of a boss and has a protective pad at its bottom. A mounting plate 3 is welded to the side wall of the base 1, and the mounting plate 3 is connected to the base plate 2 by bolts. The boss-shaped base plate 2 enhances the overall stability of the component. The protective pad at the bottom of the base plate 2 can effectively prevent direct friction damage between the component and the placement surface. The welded mounting plate 3, together with the bolt connection, achieves a firm fixation between the base 1 and the base plate 2. At the same time, the bolt connection facilitates subsequent disassembly and maintenance.
[0020] like Figures 1 to 6As shown, the push plate 10 further includes a notch 11, with a strip groove 12 on the inner wall of the notch 11. The strip groove 12 is in the shape of a straight line. The push rod 13 is located inside the notch 11, and a slide rod 14 is installed on the side wall of the push rod 13. The slide rod 14 is slidably mounted on the strip groove 12. A flat plate 15 is installed at one end of the push rod 13. The cross-sectional area of the flat plate 15 is larger than that of the push rod 13, and the flat plate 15 corresponds to the end of the positioning frame 4. The notch 11 and the strip groove 12 of the push plate 10 provide a stable sliding guide for the slide rod 14. The flat plate 15 increases the contact area between the push rod 13 and the positioning frame 4 to avoid excessive local stress. The limiting seat 16 achieves precise guidance of the push rod 13. The baffle 17 cooperates with the compression spring 18 to achieve automatic reset of the push rod 13. The limiting plate 19 prevents the push rod 13 from falling off.
[0021] like Figures 1 to 6 As shown, a limiting seat 16 is movably inserted into the push rod 13. The limiting seat 16 is installed inside the push block 8. A limiting plate 19 is installed at the other end of the push rod 13. The diameter of the limiting plate 19 is larger than the diameter of the push rod 13. A baffle 17 is installed on the side wall of the push rod 13. A compression spring 18 is sleeved on the push rod 13 between the baffle 17 and the limiting seat 16. One end of the compression spring 18 is engaged with the limiting seat 16, and the other end is engaged with the baffle 17. The baffle 17 and the compression spring 18 cooperate to realize the automatic reset of the push rod 13.
[0022] The implementation principle of a connector pin bending assembly is as follows: Before operation, the connector to be processed is precisely clamped into the slot 5 of the positioning frame 4. The size of the slot 5 is adapted to the connector, so as to realize the quick positioning and fixation of the connector and ensure that the pin is in the preset position to be bent.
[0023] The hydraulic push rod 7, mounted on the bracket 6, is activated. The output end of the hydraulic push rod 7 generates axial thrust, which pushes the push block 8 to move smoothly towards the positioning frame 4. Since the pressure plate 9, which is rotatably mounted on the side wall of the push block 8, is initially in an inclined state, the pressure plate 9 will first contact the pins of the connector in the slot 5 under the action of the push block 8. As the push block 8 continues to advance, the pressure plate 9 applies a uniform squeezing force to the pins, causing the pins to bend initially along the inclined surface of the pressure plate 9. The angle of the initial bending is determined by the initial inclination angle of the pressure plate 9, laying the foundation for subsequent precise bending.
[0024] As the pusher block 8 drives the pressure plate 9 to bend initially, the pusher plate 10, which is connected to the rotation center of the pressure plate 9, also moves synchronously with the pusher block 8. The pusher rod 13 in the notch 11 of the pusher plate 10 moves together towards the positioning frame 4 under the drive of the pusher block 8. When the flat plate 15 at the end of the pusher rod 13 (whose cross-sectional area is larger than that of the pusher rod 13, which can increase the contact area with the positioning frame 4 and avoid excessive local stress) contacts the side wall of the positioning frame 4 and is squeezed, the pusher rod 13 slides into the pusher block 8 under the guidance of the limiting seat 16 inside the pusher block 8. At this time, the baffle 17 on the side wall of the pusher rod 13 squeezes the compression spring 18 located between the baffle 17 and the limiting seat 16, causing the compression spring 18 to undergo elastic deformation and store elastic potential energy. At the same time, the slide bar 14 on the side wall of the push rod 13 slides along the strip groove 12 on the inner side wall of the notch 11 of the push plate 10. Through the cooperation and transmission of the slide bar 14 and the strip groove 12, the push plate 10 is driven to rotate around its rotation center with the push block 8. The pressure plate 9 rotates synchronously with the push plate 10, so that the pin, which was originally in the initial bending state, gradually takes shape under the further bending action of the pressure plate 9, and finally becomes vertical, completing the precise bending operation of the entire pin.
[0025] When the pin is bent to a vertical position, the hydraulic push rod 7 drives the push block 8 to reset to the initial position. At this time, the squeezing force on the push rod 13 disappears, the compression spring 18 releases elastic potential energy, pushes the baffle 17 to reset the push rod 13, and the push rod 13 drives the push plate 10 and the pressure plate 9 to return to the initial tilted state through the cooperation of the slide rod 14 and the strip groove 12. Then the bent connector can be taken out from the slot 5 of the positioning frame 4 for the next bending operation.
