Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more particularly to stamping equipment and methods for high-current flat terminals. Background Technology

[0002] For plug-in terminals in high-current scenarios, in order to improve current carrying capacity and plug-in stability, existing technologies use multiple layers of copper sheets stacked together, with both inner and outer copper sheets in a toothed shape. The top teeth are arranged in an interlaced manner and aligned on the same plane, so that after the male terminal plug is inserted, the surface is pressed against multiple contact points to reduce contact resistance.

[0003] In the traditional processing of high-current flat terminals, wire cutting, molding, and stretching need to be completed independently by separate equipment. The workpiece needs to be transferred and clamped multiple times, resulting in long processing cycles, complicated process connections, and the possibility of positioning deviations during secondary clamping.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The high-current flat terminal stamping equipment disclosed in this invention is mainly used in traditional processing where wire cutting, molding, and stretching are completed by separate equipment. The workpiece needs to be transferred and clamped multiple times, resulting in long cycles, complicated connections, and clamping deviations affecting terminal accuracy and batch consistency.

A movable seat 16 is provided in front of the support plate 12. A wire cutting embedding assembly 17 is provided in front of the movable seat 16. The wire cutting embedding assembly 17 is located above the terminal manufacturing machine 1. The wire cutting embedding assembly 17 includes a vertical frame 1701. A rotary motor 1703 is provided at the top of the vertical frame 1701. The power output shaft of the rotary motor 1703 is connected to a threaded rotating rod 1702 through a coupling. Both ends of the threaded rotating rod 1702 are movably connected to the inner sides of the vertical frame 1701. A movable plate 1704 is movably connected to the outer side of the threaded rotating rod 1702. Two wire cutting machines 1716 are provided in front of the movable plate 1704. Two inner and outer molds 1712 are provided in the middle of the wire cutting machines 1716. An inner mold 1714 is provided in the middle of the inner and outer molds 1712.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 An extension plate 1705 is provided in front of the moving plate 1704. Two electric telescopic rods 1706 are fixedly connected to the top of the extension plate 1705. A symmetrical plate 1707 is fixedly connected to the telescopic ends of the electric telescopic rods 1706. The top of the wire cutting machine 1716 is fixedly connected to the bottom of the symmetrical plate 1707. An intermediate plate 1708 is fixedly connected to the opposite side of the symmetrical plate 1707. An upper plate 1709 is fixedly connected to the top of the intermediate plate 1708. A lowering device 1710 is provided at the top of the upper plate 1709. A circular hole is opened on the intermediate plate 1708. The bottom end of the lowering device 1710 is movably connected to the inside of the circular hole. An L-shaped plate 1711 is fixedly connected to the bottom end of the lowering device 1710.

[0022] In this design, the front end of the L-shaped plate 1711 is fixedly connected to the side of the inner and outer molds 1712 near the electric telescopic rod 1706, and both inner and outer molds 1712 are fixedly connected to the side of the electric telescopic rod 1706 with fasteners 1713.

[0023] In this design, a through hole is provided on one side of the L-shaped plate 1711, and the fasteners 1713 are all movably connected inside the through hole. Two rotating motors 1715 are provided on the side of the L-shaped plate 1711 away from the inner mold 1714. The power output shafts of the rotating motors 1715 are connected to the end of the fasteners 1713 away from the middle and outer molds 1712 through a coupling.

[0024] Specifically, after the metal plate is adjusted to the preset angle, the wire cutting embedding assembly 17 is started. First, the rotary motor 1703 of the wire cutting embedding assembly 17 is started. The power output shaft of the rotary motor 1703 drives the threaded rotating rod 1103 to rotate through the coupling. Since the two ends of the threaded rotating rod 1103 are movably connected to the inner sides of the vertical frame 1701, and the moving plate 1704 is movably connected to the outer side of the threaded rotating rod 1103, the rotation of the threaded rotating rod 1103 will be converted into the linear motion of the moving plate 1704, which drives the moving plate 1704 to move downward along the inner side of the vertical frame 1701 until the moving plate 1704 moves to the height corresponding to the top of the metal plate. Simultaneously, the two electric telescopic rods 1706 at the top of the extension plate 1705 in front of the moving plate 1704 are activated in sync. The telescopic ends of the electric telescopic rods 1706 push the symmetrical plate 1707 forward. The wire cutting machine 1716, which is fixedly connected to the bottom of the symmetrical plate 1707, moves forward in sync with the symmetrical plate 1707 until the cutting head of the wire cutting machine 1716 is aligned with the top of the metal plate. At this time, the interval machine (three-head interval machine) is triggered to start. The cutting head of the wire cutting machine 1716 will perform precise wire cutting on the top of the metal plate, dividing the metal plate into four equal parts evenly according to the preset path. The metal plate will remain stationary during the cutting process to ensure cutting accuracy. After cutting, the rotary motor 1703 rotates in the opposite direction, driving the threaded rotating rod 1103 to rotate in the opposite direction, causing the moving plate 1704 to move upward along the inner side of the vertical frame 1701 until the moving plate 1704 returns to its initial height; then, the lowering device 1710 at the top of the upper plate 1709 is activated. The output end of the lowering device 1710 first pushes the L-shaped plate 1711 upward a certain distance, and then drives the L-shaped plate 1711 downward, so that the L-shaped plate 1711 passes over the two wire cutting machines 1716 and moves to below the wire cutting machines 1716. At this time, the front end of the L-shaped plate 1711 is fixed. The middle and outer molds 1712 and the inner mold 1714, which are fixedly connected, will be aligned with the cut metal plate. After the middle and outer molds 1712 and the inner mold 1714 move to the height corresponding to the metal plate, the lowering device 1710 continues to drive the L-shaped plate 1711 to move downward, so that the middle and outer molds 1712 and the inner mold 1714 fit against the surface of the cut metal plate and mold the metal plate. During the molding process, the middle and outer molds 1712 will cooperate with the inner mold 1714 to completely separate the four cut metal plates and make the shape of the metal plate match the inner cavity of the mold, thus completing the initial shaping of the metal plate. After the metal sheet is molded, the two rotating motors 1715 on the side of the L-shaped plate 1711 away from the inner mold 1714 are activated. One rotating motor 1715 rotates clockwise, and the other rotating motor 1715 rotates counterclockwise. The power output shaft of the rotating motor 1715 drives the fixed part 1713 to rotate through a coupling. Since the fixed part 1713 is movably connected inside the through hole on one side of the L-shaped plate 1711, and the end of the fixed part 1713 away from the rotating motor 1715 is fixedly connected to the inner and outer molds 1712, the fixed part 1713... The rotation will cause the inner and outer molds 1712 to expand outward. During the outward expansion of the inner and outer molds 1712, the metal plates between the molds will extend outward synchronously, so that the shape of the metal plates is further matched with the expansion trajectory of the molds, until the extension degree of the metal plates meets the preset requirements. At this point, the wire cutting and embedding process of the metal plates is completed. Then, the rotary motor 1703 is started again, driving the threaded rotating rod 1103 to rotate, so that the moving plate 1704 moves upward along the inner side of the vertical frame 1701 until the wire cutting and embedding assembly 17 is reset to the initial height.

[0025] In specific application scenarios, the integration of wire cutting and molding functions allows for the completion of segmentation, shaping, and extension processes without the need to transfer the workpiece, significantly shortening the processing cycle and avoiding secondary clamping errors.

[0026] It should be noted that achieving high-precision matching of metal plate equal division cutting, molding and directional stretching ensures the consistency of terminal dimensions.

[0027] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 The terminal manufacturing machine 1 has a worktable 4 fixedly connected to its top. The worktable 4 has a pressure-rotating assembly 11 inside. The pressure-rotating assembly 11 includes a servo motor 1101. The bottom end of the servo motor 1101 is fixedly connected to the bottom end of the worktable 4. The power output shaft of the servo motor 1101 is connected to a rotating rod 1103 through a coupling. A support frame 1102 is fixedly connected to the outside of the rotating rod 1103. A rotating circular plate 1104 is fixedly connected to the top of both the support frame 1102 and the rotating rod 1103.

[0028] In this design, two rectangular holes are provided on the rotating circular plate 1104. A circular rod 1105 is fixedly connected inside the rectangular holes. A movable seat 1108 is movably connected to the outer side of the circular rod 1105. A sliding plate 1107 is fixedly connected to the top of the movable seat 1108. A telescopic electric rod 1106 is fixedly connected to the side of the sliding plate 1107 near the support frame 1102. One side of the telescopic electric rod 1106 is fixedly connected to the outer side of the support frame 1102.

[0029] In this design, a pressure plate 1109 is fixedly connected to the top of each movable seat 1108. A rear frame 1111 is fixedly connected to the opposite side of each pressure plate 1109. A spring-loaded rod 1110 is provided on the inner side of each rear frame 1111. A spring-loaded plate 1112 is fixedly connected to the outer side of each spring-loaded rod 1110. A pressing plate 1113 is fixedly connected to the opposite side of each pressing plate 1112. A pressing spring 1114 is fixedly connected to the opposite side of each pressing plate 1113. An auxiliary plate 1115 is fixedly connected to the opposite side of each pressing spring 1114.

[0030] Specifically, before the operation begins, the operator places the metal plate to be processed stably on the rotating circular plate 1104 of the fixed pressure rotating assembly 11. At this time, the fixed pressure plate 1109 is in the initial open state, leaving enough space for the metal plate. After the electric telescopic rod 1706 of the fixed pressure rotating assembly 11 is started, the telescopic end of the telescopic rod will push the sliding plates 1107 on both sides to slide along the circular rod 1105 in the rectangular hole on the rotating circular plate 1104, which will drive the movable seat 1108 connected to the sliding plate 1107 to move towards the center of the rotating circular plate 1104, thereby making the fixed pressure plate 1109 at the top of the movable seat 1108 move closer to each other. After the metal plate is clamped, the servo motor 1101 of the fixed pressure rotating assembly 11 is started. The power output shaft of the servo motor 1101 drives the rotating rod 1103 to rotate through the coupling. The support frame 1102 on the outside of the rotating rod 1103 will rotate synchronously with the rotating rod 1103. Since the top of the support frame 1102 and the rotating rod 1103 are fixedly connected to the rotating circular plate 1104, the rotating circular plate 1104 will rotate together with the support frame 1102 and the rotating rod 1103 until the long side of the metal plate is parallel to the observation window 2. At this time, the placement angle of the metal plate meets the processing requirements of the wire cutting embedded assembly 17. The fixed pressure rotating assembly 11 stops rotating and enters the waiting state. After the wire cutting embedded component 17 is reset, the servo motor 1101 of the fixed pressure rotating component 11 is restarted, driving the rotating rod 1103 to rotate, which in turn drives the rotating circular plate 1104 to rotate synchronously, so that the narrower side of the metal plate is adjusted to a position parallel to the observation window 2. At this time, the placement angle of the metal plate meets the processing requirements of the stamping head 10. The fixed pressure rotating component 11 stops rotating, and the tooth row of the stamping head 10 fits against the middle area of ​​the top of the metal plate, performing tooth row stamping processing on the metal plate, forming a tooth-shaped structure on the surface of the metal plate that matches the tooth row of the stamping head 10. After stamping is completed, the electric telescopic rod 1706 extends and retracts, pushing the sliding plate 1107 to slide along the round rod 1105, causing the metal plate to move a distance away from the stamping head 10, so that the metal plate formed by the middle and foreign molds 1712 is precisely located above the stamping head 10. After the metal plate moves to the preset position, the stamping head 10 performs toothed connection processing on the two metal plates shaped by the middle and foreign molds 1712, so that the teeth of the metal plates mesh with each other, and completes the integrated forming operation of the high current flat plug terminal.

[0031] In specific application scenarios, the servo motor 1101 drives the metal plate to rotate at multiple angles, accurately matching the processing posture requirements of different processes such as wire cutting and stamping, and ensuring the consistency of positioning in each process.

[0032] It should be noted that the elastic clamping structure of the pressure plate 1109, together with the rebound rod 1110 and the pressing spring 1114, can not only firmly fix the metal plate, but also buffer the impact force of processing, avoid workpiece deformation or displacement, and improve processing accuracy.

[0033] Reference Figures 1-4 In a preferred embodiment, an observation window 2 is fixedly connected to the top of the terminal manufacturing machine 1. An opening and closing door 3 is provided at the front end of the observation window 2. A worktable 4 is located inside the observation window 2. The inner side of the observation window 2 is fixedly connected to both sides of a support plate 12. A connecting frame 13 is fixedly connected to the front end of the support plate 12. A drive motor 14 is fixedly connected to one side of the inner side of the connecting frame 13. The power output of the drive motor 14 is connected to a threaded rod 15 via a coupling. The end of the threaded rod 15 away from the drive motor 14 is movably connected to the inner side of the connecting frame 13. The outer side of the threaded rod 15 of the outer side of the frame 13 is movably connected to the inner side of the movable seat 16. The top of the worktable 4 is fixedly connected to the linear rail 5. The top of the linear rail 5 is provided with a linear sliding seat 6. The top of the linear sliding seat 6 is fixedly connected to the lifting frame 7. The top of the linear sliding seat 6 is fixedly connected to the extension device 8. The lifting frame 7 has a hole.

The side of the connecting plate 9 near the fixed pressure rotating assembly 11 is fixedly connected to the punch head 10.

[0034] The method of using the high-current flat terminal stamping equipment, as described above, includes the following steps: Step 1: The metal plate is placed on the rotating circular plate 1104 and clamped and fixed by the pressure plate 1109. The servo motor 1101 drives the rotating circular plate 1104 to adjust the angle so that the long side of the metal plate is parallel to the observation window 2. Step 2: The wire cutting embedded component 17 moves down, and the wire cutting machine 1716 cuts the metal plate into four equal parts. The outer mold 1712 and the inner mold 1714 cooperate to complete the molding and segmentation. Step 3: The dual rotating motors 1715 rotate in one direction and the other in the opposite direction, driving the inner and outer molds 1712 to expand outward, pushing the metal plate to extend synchronously, and the component is reset after the wire cutting and embedding process is completed. Step 4: The fixed pressure rotating assembly 11 is adjusted again to make the narrow side of the metal plate parallel to the observation window 2, and the punching head 10 is moved to the corresponding position to perform toothed punching on the metal plate. Step 5: Adjust the relative position of the stamping head 10 and the metal plate, and stamp again to achieve toothed connection and complete the integrated forming of the terminal.
