[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] Example: Please refer to Figures 1-6 This embodiment provides a bending machine for connected round fork type terminals, including a frame 1. A bending mechanism for connected round fork type terminals is installed on the top of the frame 1. A take-up tray 2 is installed on one side of the frame 1, and a take-up motor is installed on the back of the take-up tray 2. The take-up motor drives the take-up tray 2 to rotate, which is used to wind up and collect the bent connected round fork type terminals. The bending mechanism for connected round fork type terminals includes a support frame 3, a connected round fork type terminal material groove 4 horizontally installed on the support frame 3, and a material support roller assembly 5 installed on the side of the support frame 3 away from the take-up tray 2. The material support roller assembly 5 corresponds to the position of the connected round fork type terminal material groove 4. A pressing assembly 6 is provided inside the support frame 3 and above the connected round fork type terminal material groove 4. Inside the frame 3 and below the connecting round fork terminal material groove 4, a bending assembly 7 is installed. The connecting round fork terminals conveyed in the connecting round fork terminal material groove 4 are bent at the bending assembly 7, exposing the part to be bent. A pulling assembly 8 is installed on the side of the support frame 3 away from the material support roller assembly 5. In use, the connecting round fork terminals are guided into the connecting round fork terminal material groove 4 by the material support roller assembly 5. The pulling assembly 8 drives the connecting round fork terminals to be conveyed. The pressing assembly 6 presses and fixes the connecting round fork terminals to be bent. Then, the bending assembly 7 bends the connecting round fork terminals, realizing continuous and automated processing of connecting round fork terminals, greatly improving processing efficiency.
[0028] In this embodiment, a protective cover is installed on the outside of the support frame 3 to protect the moving structure of the pressing assembly 6 and the bending assembly 7.
[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the pressing assembly 6 includes a first fixed shaft 601 fixedly connected to the front side of the top end inside the support frame 3, a positioning pressure plate 606, and a connecting rod connecting the first fixed shaft 601 and the positioning pressure plate 606. A second fixed shaft 602 is fixedly connected to the rear side of the top end inside the support frame 3. A first cylinder 603 is provided between the second fixed shaft 602 and the connecting rod. A first clearance groove for the positioning pressure plate 606 to pass through is provided on the circular fork-shaped terminal material groove 4.
[0030] In this embodiment, as Figure 2 and Figure 3 As shown, the linkage includes a pair of first connecting rods 604 and a pair of second connecting rods 605. The ends of the first connecting rods 604 and the second connecting rods 605 that are close to each other are rotatably connected. The other end of the first connecting rod 604 is rotatably connected to the first fixed shaft 601. The other end of the second connecting rod 605 is rotatably connected to the positioning pressure plate 606. The telescopic end of the first cylinder 603 is rotatably connected to the connection between the first connecting rods 604 and the second connecting rods 605. The other end of the first cylinder 603 is rotatably connected to the second fixed shaft 602.
[0031] In this embodiment, as Figure 2 and Figure 3 As shown, pressure plate slides 607 are fixedly connected to both sides of the support frame 3 at the corresponding positioning pressure plates 606. A sliding groove is opened on the pressure plate slide 607 along the vertical direction. Slider blocks that are slidably connected to the sliding groove are fixedly connected to both sides of the positioning pressure plate 606.
[0032] Specifically, by extending the first cylinder 603, the first connecting rod 604 and the second connecting rod 605 are rotated to adjust their angles, making the first connecting rod 604 and the second connecting rod 605 tend to be vertical, so as to push the positioning pressure plate 606 downward. During the movement of the pressure plate slide 607, the positioning pressure plate 606 slides in the slide groove of the pressure plate slide 607 through the slider, which plays a limiting and guiding role for the positioning pressure plate 606, so as to ensure that the positioning pressure plate 606 moves in the vertical direction, so that the pressure plate slide 607 passes through the first clearance groove and presses against the connecting round fork terminal inside the connecting round fork terminal material groove 4, thereby fixing the position of the connecting round fork terminal at the bending point and avoiding displacement during bending processing, which would affect the bending effect.
[0033] In this embodiment, as Figure 2 , Figure 4 and Figure 5As shown, the bending assembly 7 includes a lower bending slide 701 disposed inside the support frame 3 and an upper bending slide 702 disposed on the top of the lower bending slide 701. A bending plate 703 corresponding to the position of the connecting round fork-shaped terminal material groove 4 is fixedly connected to the top of the upper bending slide 702. A bending cylinder fixing seat 704 is fixedly connected to the rear end inside the support frame 3. A second cylinder 705 is rotatably connected to the bending cylinder fixing seat 704. The telescopic end of the second cylinder 705 is rotatably connected to the lower bending slide 701. A limit sliding structure is provided between the lower bending slide 701 and the upper bending slide 702 and the support frame 3.
[0034] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, the limiting sliding structure includes a lower bending track 301 and an upper bending track 302 opened on both sides of the support frame 3. The lower bending track 301 corresponds to the lower bending slide 701, and the upper bending slide 702 corresponds to the upper bending track 302. Both sides of the lower bending slide 701 are rotatably connected to a first limiting roller 708 placed inside the lower bending track 301, and both sides of the upper bending track 302 are rotatably connected to a second limiting roller 709 placed inside the upper bending track 302.
[0035] Specifically, in the initial state, the lower bending slide 701 and the upper bending slide 702 are in a horizontal position, the bending plate 703 is located above the part of the connected round fork-shaped terminal to be bent, and the second cylinder 705 is in an extended state. When bending the connected round fork-shaped terminal, the second cylinder 705 gradually retracts, thereby driving the lower bending slide 701 and the upper bending slide 702 to move. The lower bending track 301 moves and rotates along the lower bending track 301 through the first limiting roller 708 to adjust the angle, and the upper bending slide 702 moves and rotates along the upper bending track 302 through the second limiting roller 709 to adjust the angle. This allows the lower bending slide 701 and the upper bending slide 702 to dynamically adjust from a horizontal position to a vertical position, thereby achieving a seamless bending of the connected round fork-shaped terminal.
[0036] In this embodiment, as Figure 4 As shown, the upper bending slide 702 has a dovetail groove 7021 on the side near the lower bending slide 701, and the lower bending slide 701 has a dovetail block 7011 fixedly connected to the side near the upper bending slide 702, which slides with the dovetail groove 7021. The dovetail groove 7021 and the dovetail block 7011 allow the upper bending slide 702 and the lower bending slide 701 to slide relative to each other to adjust their positions, so as to adapt to the dynamic adjustment of the lower bending slide 701 and the upper bending slide 702.
[0037] In this embodiment, as Figure 5As shown, a buffer mounting base 706 is fixedly connected inside the support frame 3 and below the bending cylinder mounting base 704. A hydraulic buffer 707 is fixedly installed on the buffer mounting base 706. A connecting block that cooperates with the hydraulic buffer 707 is fixedly connected to the lower bending slide 701. When the lower bending slide 701 is adjusted to a vertical state, the connecting block impacts the hydraulic buffer 707, reducing the impact force and improving the structural stability.
[0038] In this embodiment, as Figure 6 As shown, the material pulling assembly 8 includes a connecting plate 801 fixedly connected to one side of the support frame 3. A servo motor 802 is fixedly connected to the upper back of the connecting plate 801. The output end of the servo motor 802 passes through the connecting plate 801 and is fixedly connected to a material pulling wheel 803. A third cylinder 804 is fixedly installed on the lower front end of the connecting plate 801. The telescopic end of the third cylinder 804 faces upward and is fixedly connected to a mounting base 805. A pressure wheel 806 is rotatably connected to one side of the mounting base 805. The pressure wheel 806 is located below the connected round fork-shaped terminal groove 4, and the material pulling wheel 803 is located above the connected round fork-shaped terminal groove 4. The 6 is distributed vertically and vertically with the pull roller 803. The connecting round fork type terminal material groove 4 is provided with a second clearance groove for the pressure roller 806 and the pull roller 803 to pass through. When conveying the connecting round fork type terminal, the pressure roller 806 is driven to move vertically upward by the third cylinder 804, clamping the connecting round fork type terminal between the pressure roller 806 and the pull roller 803. Then, the pull roller 803 is driven to rotate by the servo motor 802 to realize the conveying of the connecting round fork type terminal. Moreover, by adjusting the position of the pressure roller 806, it can be adapted to conveying connecting round fork type terminals of different specifications, thus improving applicability.
[0039] In this embodiment, as Figure 1 As shown, four casters are installed at the bottom of the frame 1. The casters are arranged in a rectangular pattern and are self-locking, which facilitates the movement and adjustment of the bending machine.
[0040] In this embodiment, the first cylinder 603, the second cylinder 705, and the third cylinder 804 are existing technologies, equipped with pneumatic drive structures, etc. Their specific structures and working principles will not be described in detail here.
[0041] Working principle: During use, the connected round fork type terminal is guided into the connected round fork type terminal trough 4 by the material support roller assembly 5. The third cylinder 804 drives the pressure roller 806 to move vertically upward, clamping the connected round fork type terminal between the pressure roller 806 and the pull roller 803. Then, the servo motor 802 drives the pull roller 803 to rotate, driving the connected round fork type terminal to be conveyed. The bent connected round fork type terminal is then wound up and collected by the take-up tray 2. When the bent connected round fork type terminal moves to the bending position, the first cylinder 603 extends, thereby driving the first connecting rod 604 and the second connecting rod 605 to rotate and adjust the angle, so that the first connecting rod 604 and the second connecting rod 605 tend to be vertical, pushing the positioning pressure plate 606 downward, so that the pressure plate slide 607 passes through the first clearance groove and presses down. The connecting round fork type terminal is tightly attached to the connecting round fork type terminal inside the connecting round fork type terminal material groove 4, thereby fixing the position of the connecting round fork type terminal at the bending point and preventing displacement during bending. Then, the second cylinder 705 gradually retracts, thereby driving the lower bending slide 701 and the upper bending slide 702 to move. The lower bending track 301 moves and rotates along the lower bending track 301 through the first limiting roller 708 to adjust the angle, and the upper bending slide 702 moves and rotates along the upper bending track 302 through the second limiting roller 709 to adjust the angle. This allows the lower bending slide 701 and the upper bending slide 702 to dynamically adjust from the horizontal position to the vertical position, thereby realizing the seamless bending of the connecting round fork type terminal. It can simultaneously bend multiple connecting round fork type terminals, realizing continuous and automated processing of connecting round fork type terminals, and greatly improving processing efficiency.
[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
