Description

Technical Field

[0001] This utility model relates to the field of copper terminal processing technology, and in particular to molds for forming copper terminals. Background Technology

[0002] Copper terminal forming molds, also known as terminal forming molds, are devices used to process copper tubes into specific shapes under pressure to meet the connection requirements of products such as electronic connectors, wire harnesses, and cables.

[0003] However, most of the existing copper terminal forming molds on the market are not easy to disassemble and install, which increases the difficulty for workers to replace worn molds. In addition, most of the existing copper terminal forming molds on the market are not easy for workers to remove and collect the formed workpieces from the mold, which reduces the efficiency of copper terminal processing.

[0004] Therefore, those skilled in the art have provided molds for processing and forming copper terminals to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a mold for processing and forming copper terminals. The connecting block in the connecting mechanism is slidably connected to the connecting groove. With the help of the return spring acting on the locking block on the rotating rod, the locking block is locked to the locking groove, which facilitates the assembly and disassembly of the mold. The electric telescopic rod in the collecting mechanism drives the insertion rod to move. With the help of the servo motor driving the drive gear and the driven gear, the transmission rod drives the support block to rotate, which facilitates the removal of the workpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mold for processing and forming copper terminals includes a base, a pressure plate, a connecting mechanism, and a collecting mechanism. A collecting box is fixedly connected to the front end of the lower end of the base. A connecting mechanism is provided at the upper end of the base. The connecting mechanism includes an upper mold, a lower mold, and four rotating rods. Connecting blocks are fixedly connected to both sides of the upper end of the base and both sides of the lower end of the pressure plate. Connecting grooves are provided on both sides of the upper end of the upper mold and both sides of the lower end of the lower mold. Rotating grooves are provided at the front and rear ends of both sides of the inner sides of the upper and lower molds. A return spring is fixedly connected to the inner wall of the other side of the rotating groove. A locking block is fixedly connected to both sides of the outer wall of the rotating rod. Locking grooves are provided at the front and rear ends of both sides of the upper end of the upper mold and the front and rear ends of both sides of the lower end of the lower mold.

[0008] The front ends of the rotating rods all pass through the rotating grooves and are fixedly connected to the actuating blocks. The rear ends of both sides of the upper end of the base are fixedly connected to the guide rods. The base is equipped with a collection mechanism, which includes a transmission rod. The lower end of the middle of the front end of the base is provided with a receiving cavity. A servo motor is provided on the inner wall of one side of the receiving cavity. The rear end of the middle of the upper end of the base is fixedly connected to a side plate. The upper ends of the outer walls of the guide rods are fixedly connected to the side plates. A hydraulic rod is provided at the center of the upper end of the side plates.

[0009] Through the above technical solution, the connecting block fixedly connected to the base and pressure plate in the connecting mechanism is slidably connected to the connecting grooves opened on the lower mold and the upper mold. With the help of the return spring acting on the locking block on the rotating rod, the locking block is kept engaged with the locking grooves on the upper mold and the lower mold, thus fixing the mold. By using the actuating block to drive the locking block on the rotating rod to rotate in the rotating groove, the engagement with the locking groove can be released, thereby facilitating the disassembly and installation of the mold by the workers.

[0010] Furthermore, a driven gear is fixedly connected to the middle of the outer wall of the transmission rod, a driving gear is fixedly connected to the output shaft of the servo motor, support blocks are fixedly connected to both sides of the transmission rod through the base, a limit block is fixedly connected to the upper end of each support block, an electric telescopic rod is provided on the side of each limit block away from the center of the base, and an insertion rod is fixedly connected to the output shaft of each electric telescopic rod through the limit block.

[0011] The above technical solution involves using an electric telescopic rod on the limiting block in the collecting mechanism to move the insertion rod, which then penetrates into the circular hole of the workpiece. A servo motor drives the active gear, which in turn drives the driven gear to rotate the support block. This causes the insertion rod to lift the workpiece and rotate it out of the base. The electric telescopic rod then retracts the insertion rod back into the limiting block, causing the workpiece to fall out and making it easier to remove.

[0012] Furthermore, support legs are fixedly connected to the rear ends of both sides of the lower end of the base, and a PLC control panel is provided on one side of the collection box;

[0013] The above technical solution allows the entire device to be stably positioned in the workshop by fixing two support legs to the lower end of the base and a collection box to the lower end of the base. The PLC control panel inside the collection box allows staff to easily control the device's operating status.

[0014] Furthermore, all the connecting slots are slidably connected to the connecting blocks, and all the locking blocks are snapped into the locking slots;

[0015] The above technical solution restricts the left and right movement of the mold by allowing the connecting block fixedly connected to the base and the pressure plate to slide in the connecting grooves opened on the lower and upper molds. The back and forth movement of the mold can be restricted by using the locking block to engage with the locking grooves opened on the upper and lower molds, thereby fixing the mold in place.

[0016] Furthermore, both the base and the pressure plate are rotatably connected to the middle of the outer wall of the rotating rod, and one side of the return spring is fixedly connected to the locking block;

[0017] The above technical solution applies spring force to the fixed block on the rotating rod through the reset spring, causing the block to rotate with the rotating rod, thereby enabling the block to maintain its engagement with the upper and lower mold slots.

[0018] Furthermore, a discharge port is provided at the center of the upper end of the base, and a discharge hopper is fixedly connected at the center of the lower end of the base;

[0019] The above technical solution involves opening a discharge port at the center of the upper end of the base and fixing a discharge hopper below the base. This allows the workpiece waste generated when the upper mold presses down on the lower mold to pass through the holes and discharge port on the lower mold and be discharged by the discharge hopper.

[0020] Furthermore, the middle part of the outer wall of the guide rod is slidably connected to the pressure plate, and the output shaft of the hydraulic rod passes through the side plate and is fixedly connected to the pressure plate;

[0021] The above technical solution provides power to the pressure plate through the hydraulic rod on the side plate, so that the pressure plate can move up and down along the guide rod with the upper mold. When the upper mold contacts the lower mold, the workpiece blank is cut into two sections and shaped, and the waste is pushed out of the hole on the lower mold.

[0022] Furthermore, both sides of the outer wall of the transmission rod are rotatably connected to the base, and the driving gear is meshed with the driven gear;

[0023] The above technical solution uses a servo motor to drive the active gear to rotate, and through the driven gear meshing with the active gear, the transmission rod can rotate within the base, thereby driving the support block to rotate.

[0024] This utility model has the following beneficial effects:

[0025] 1. The copper terminal processing mold proposed in this utility model has a connecting block fixedly connected to the base and pressure plate in the connecting mechanism, which is slidably connected to the connecting grooves opened on the lower mold and the upper mold. With the help of the return spring acting on the locking block on the rotating rod, the locking block is kept in the locking connection with the locking grooves on the upper mold and the lower mold, thus fixing the mold. The locking block on the rotating rod can be released by using the actuating block to drive the locking block to rotate in the rotating groove, thereby facilitating the disassembly and assembly of the mold by the workers and reducing the difficulty of replacing worn molds.

[0026] 2. The copper terminal processing mold proposed in this utility model uses an electric telescopic rod on the limiting block in the collecting mechanism to move the insertion rod and insert it into the round hole of the workpiece. With the help of a servo motor driving the drive gear and the driven gear, the transmission rod drives the support block to rotate, causing the insertion rod to lift the workpiece and rotate it out of the base. The electric telescopic rod then retracts the insertion rod into the limiting block, causing the workpiece to fall. This makes it easier for workers to remove and collect the processed workpiece from the mold, thus improving the efficiency of copper terminal processing. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 7 The present invention provides a specific embodiment of a mold for processing and forming copper terminals, including a base 1, a pressure plate 5, a connecting mechanism 6 and a collecting mechanism 9. A collecting box 2 is fixedly connected to the front end of the lower end of the base 1. A connecting mechanism 6 is provided at the upper end of the base 1. The connecting mechanism 6 includes an upper mold 603, a lower mold 604 and four rotating rods 607. Connecting blocks 601 are fixedly connected to both sides of the upper end of the base 1 and both sides of the lower end of the pressure plate 5. Connecting grooves 602 are provided on both sides of the upper end of the upper mold 603 and both sides of the lower end of the lower mold 604. Rotating grooves 605 are provided at the front and rear ends of both sides of the inner sides of the upper mold 603 and the lower mold 604. A return spring 606 is fixedly connected to the inner wall of the other side of the rotating groove 605. A locking block 608 is fixedly connected to both sides of the outer wall of the rotating rod 607. A locking groove 609 is provided at the front and rear ends of both sides of the upper end of the upper mold 603 and the front and rear ends of both sides of the lower end of the lower mold 604.

[0038] The front end of the rotating rod 607 passes through the rotating groove 605 and is fixedly connected to the actuating block 610. The rear ends of both sides of the upper end of the base 1 are fixedly connected to the guide rod 8. The base 1 is equipped with a collection mechanism 9, which includes a transmission rod 904. The lower end of the middle of the front end of the base 1 is provided with a receiving cavity 901. A servo motor 902 is provided on the inner wall of one side of the receiving cavity 901. The rear end of the middle of the upper end of the base 1 is fixedly connected to the side plate 11. The upper end of the outer wall of the guide rod 8 is fixedly connected to the side plate 11. A hydraulic rod 12 is provided at the center of the upper end of the side plate 11.

[0039] Support legs 3 are fixedly connected to the rear ends of both sides of the lower end of the base 1. A PLC control panel 4 is set on one side of the collection box 2. By fixing two support legs 3 to the lower end of the base 1, together with the collection box 2 fixedly connected to the lower end of the base 1, the entire equipment can be stably placed in the workshop. The PLC control panel 4 inside the collection box 2 allows the operator to easily control the operation of the equipment. The connecting slots 602 are all slidably connected to the connecting blocks 601, and the locking blocks 608 are all lockingly connected to the locking slots 609. The connecting block 601, which is fixedly connected to the base 1 and the pressure plate 5, is slidably connected to the connecting groove 602 on the lower mold 604 and the upper mold 603, restricting the left and right movement of the mold. The locking block 608 is engaged with the locking groove 609 on the upper mold 603 and the lower mold 604, restricting the forward and backward movement of the mold and thus fixing it in place. Both the base 1 and the pressure plate 5 are rotatably connected to the middle of the outer wall of the rotating rod 607. One side of the return spring 606 is fixedly connected to the locking block 608, and the return spring 606 is used to release the spring... Force is applied to the locking block 608 fixed on the rotating rod 607, causing the locking block 608 to rotate with the rotating rod 607. This allows the locking block 608 to maintain its engagement with the locking grooves 609 on the upper mold 603 and the lower mold 604. A discharge port 7 is provided at the center of the upper end of the base 1, and a discharge hopper 10 is fixedly connected to the center of the lower end of the base 1. By providing a discharge port 7 at the center of the upper end of the base 1 and a discharge hopper 10 fixedly connected to the lower end of the base 1, a force is generated when the upper mold 603 presses down on the lower mold 604. The workpiece waste passes through the holes and discharge port 7 on the lower mold 604 and is discharged by the discharge hopper 10. The middle part of the outer wall of the guide rod 8 is slidably connected to the pressure plate 5. The output shaft of the hydraulic rod 12 passes through the side plate 11 and is fixedly connected to the pressure plate 5. The hydraulic rod 12 on the side plate 11 provides power to the pressure plate 5, so that the pressure plate 5 can move up and down along the guide rod 8 with the upper mold 603. When the upper mold 603 contacts the lower mold 604, it cuts the workpiece blank into two sections and shapes it, and pushes the waste out of the holes on the lower mold 604.

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A driven gear 905 is fixedly connected to the middle of the outer wall of the transmission rod 904. A driving gear 903 is fixedly connected to the output shaft of the servo motor 902. Support blocks 906 are fixedly connected to both sides of the transmission rod 904 through the base 1. Limit blocks 907 are fixedly connected to the upper end of the support blocks 906. An electric telescopic rod 908 is provided on the side of the limit block 907 away from the center of the base 1. The output shaft of the electric telescopic rod 908 passes through the limit block 907 and is fixedly connected to the insertion rod 909.

[0041] Both sides of the outer wall of the transmission rod 904 are rotatably connected to the base 1. The driving gear 903 is meshed with the driven gear 905. The driving gear 903 is driven to rotate by the servo motor 902 and then driven by the driven gear 905 meshing with the driving gear 903, so that the transmission rod 904 can rotate within the base 1, thereby driving the support block 906 to rotate.

[0042] Working principle: When using this copper terminal to process the forming mold, the operator first uses the actuating block 610 to drive the locking block 608 on the rotating rod 607 to rotate in the rotating groove 605, releasing the locking connection to the locking groove 609. The upper mold 603 and the lower mold 604 are then removed from the pressure plate 5 and the base 1 along the connecting groove 602. The new mold is then slid into the connecting groove 602 using the connecting block 601. At this time, under the action of the return spring 606, the locking block 608 rotates with the rotating rod 607 in the rotating groove 605 and engages with the locking groove 609, completing the mold replacement. Next, the operator places the workpiece blank on the lower mold 604 and starts the hydraulic rod 12 through the PLC control panel 4 to drive the pressure plate 5 to carry the upper mold 603 along the guide rod 8 to press the workpiece. The blank undergoes forming processing. After the pressing is completed and the pressure plate 5 moves upward, the operator starts the servo motor 902 through the PLC control panel 4 to drive the drive gear 903 and then the driven gear 905. This causes the transmission rod 904 to rotate the limiting block 907 fixedly connected to the support block 906 from the collection box 2 to the lower mold 604. Finally, the electric telescopic rod 908 inserts the insertion rod 909 into the round hole of the workpiece. With the servo motor 902 driving the drive gear 903 and then the driven gear 905, the transmission rod 904 rotates, removing the workpiece from the lower mold 604 and placing it above the collection box 2. Then, the electric telescopic rod 908 retracts the insertion rod 909 back into the limiting block 907, causing the workpiece to fall into the collection box 2, completing the collection of the workpiece.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
