[0002] U-shaped clips are widely used in many industries, such as automobile manufacturing, electronic equipment, and mechanical assembly. Traditional U-shaped clip production methods often suffer from low efficiency and difficulty in guaranteeing precision. Manual bending is not only labor-intensive but also results in inconsistent product quality, failing to meet the demands of large-scale production. Existing bending equipment is often complex in structure, inconvenient to operate, and poorly adaptable to different specifications of metal strips, requiring frequent adjustments to equipment parameters or mold changes, thus impacting production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bending device for the production of U-shaped buckles, so as to solve the problems of low production efficiency, difficulty in ensuring accuracy, and poor adaptability to metal strips of different specifications in the existing technology.

[0005] A bending device for producing U-shaped buckles includes a worktable with a gantry frame mounted on it. A horizontally positioned rotating seat is rotatably mounted on the worktable via bearings, and the rotating seat is connected to a rotary drive mechanism for driving its horizontal rotation. A vertically upward support column, passing through the center of the rotating seat and coaxially aligned with it, is fixedly mounted on the worktable. A fixed mold, for limiting and guiding a metal strip from one side, is mounted on the top of the support column. A bending mechanism, movable away from and close to the fixed mold, cooperates with the fixed mold and, during the rotation of the rotating seat, bends the metal strip from the other side to form a U-shaped buckle.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A bending device for producing U-shaped buckles, combined with Figures 1 to 3 As shown, the device includes a workbench 1, on which a gantry frame 2 is mounted. A clamping mechanism is installed on the gantry frame 2, which can move away from and closer to the workbench 1. The clamping mechanism is used to clamp a metal strip from one end. A rotating seat 5 is rotatably mounted on the workbench 1 via a bearing 4. The rotating seat 5 is horizontally positioned and connected to a rotation drive mechanism, which drives the rotating seat 5 to rotate horizontally. A support column 3 is fixedly mounted on the workbench 1. The support column 3 is vertically upward and passes through the center of the rotating seat 5, coaxially with it. A fixed mold 9 is mounted on the top of the support column 3. The fixed mold 9 is used to limit and guide the metal strip from one side. Simultaneously, a bending mechanism is installed on the rotating seat 5, which can move away from and closer to the fixed mold 9. The bending mechanism cooperates with the fixed mold 9 and, under the rotation of the rotating seat 5, bends the metal strip from the other side, thereby forming a U-shaped buckle.

[0020] The rotary drive mechanism includes a rotary drive motor 7, which is mounted on the worktable 1 and located on one side of the rotary seat 5. The rotating shaft of the rotary drive motor 7 is upward and connected to a gear 8. The gear 8 meshes with a gear ring 6, which is circumferentially arranged along the outer side wall of the rotary seat 5. The rotation of the rotary drive motor 7 drives the gear 8 to rotate, which in turn drives the gear ring 6 to rotate, thereby driving the rotary seat 5 to rotate.

[0021] The fixed mold 9 has a guide groove 91 circumferentially formed on its side wall. The guide groove 91 is adapted to fit one side of the metal strip, allowing it to conform to the metal strip and thus limit and guide its position during bending. A guide seat 92 is provided at the bottom of the fixed mold 9. A groove 51 is formed on the rotating seat 5, which is used to seat the guide seat 92. A circular guide rail 52 is provided in the groove 51, and the circular guide rail 52 slides in engagement with the guide seat 92. When the rotary drive mechanism drives the rotating seat 5 to rotate, the cooperation between the guide seat 92 and the circular guide rail 52 effectively ensures the stability of the fixed mold 9, thereby ensuring the accuracy of the metal strip's position during bending.

[0022] The bending mechanism includes a slide rail 11, which is radially arranged along the rotating base 5. A movable mold 10 is slidably mounted on the slide rail 11 via a slider 12. The movable mold 10 is located on one side of the fixed mold 9, and a bending groove 101 is circumferentially formed on the side of the movable mold 10 opposite to the fixed mold 9 and opposite to the guide groove 91. The bending groove 101 is used to fit with the other side of the metal strip. A translation drive cylinder 13 is connected to the side of the movable mold 10 away from the fixed mold 9. The translation drive cylinder 13 is set on the rotating base 5 and is used to drive the movable mold 10 to slide along the slide rail 11, thereby moving the movable mold 10 away from and closer to the fixed mold 9. When the movable mold 10 is close to the fixed mold 9, the bending groove 101 on the movable mold 10 can fit with the other side of the metal strip. Under the rotation of the rotating base 5, the metal strip can be bent, and when the rotating base 5 rotates 180°, a U-shaped buckle can be formed.

[0023] like Figure 4As shown, the clamping mechanism includes a lifting drive cylinder 14, which is mounted on the gantry frame 2. The telescopic rod of the lifting drive cylinder 14 is positioned downwards and connected to a lifting seat 15. A positive and negative lead screw 16 is rotatably mounted on the lower surface of the lifting seat 15. The positive and negative lead screw 16 is horizontally positioned, and a guide rail seat 17 is positioned above the positive and negative lead screw 16. The guide rail seat 17 is mounted on the lower surface of the lifting seat 15 and is parallel to the positive and negative lead screw 16. Two clamping seats 18 are slidably mounted on the guide rail seat 17. The two clamping seats 18 are respectively connected to the two lead screw nuts on the positive and negative lead screw 16, and the two clamping seats 18 are positioned opposite each other. The opposite surfaces of the two clamping seats 18 are respectively provided with clamping grooves 19. The clamping grooves 19 on both sides are adapted to the two sides of the metal strip and are used to clamp the metal strip from both ends. One end of the positive and negative lead screw 16 is connected to a clamping drive motor 20, which is mounted on the lifting seat 15. The clamping drive motor 20 drives the positive and negative lead screw 16 to rotate, thereby enabling the two clamping seats 18 to move towards and away from each other, thus clamping and releasing the end of the metal strip. The lifting drive cylinder 14 can drive the lifting seat 15 and the entire component on it to rise and fall, thereby facilitating the adjustment of the clamping position.

[0024] The fixed mold 9 has several guide grooves 91 spaced apart from top to bottom. Each guide groove 91 has a different cross-sectional shape or size, thus adapting to different metal strips. The movable mold 10 has several bending grooves 101 spaced apart from top to bottom. Each bending groove 101 has a different cross-sectional shape or size, thus cooperating with the guide grooves 91 to achieve bending of different metal strips. The clamping base 18 has several clamping grooves 19 spaced apart from top to bottom. Each clamping groove 19 has a different cross-sectional shape or size, thus achieving clamping of different metal strips. The arrangement of the guide grooves 91, bending grooves 101, and clamping grooves 19 greatly improves the applicability of the device.

[0025] To further improve the applicability of the device, the fixed mold 9, the movable mold 10 and the clamping seat 18 are a set of molds suitable for bending different metal strips, and they can be detached for easy replacement, so as to realize bending of more different metal strips.

[0026] A PLC controller is installed on the workbench 1. The output terminals of the PLC controller are connected to the controlled terminals of the clamping mechanism, bending mechanism, and rotary drive mechanism, respectively. Specifically, the output terminals of the PLC controller are connected to the controlled terminals of the rotary drive motor 7, the translation drive cylinder 13, the clamping drive motor 20, and the lifting drive cylinder 14, respectively. Through the control of the PLC controller, the various mechanisms coordinate their actions, realizing the automated production of U-shaped buckles, improving production efficiency and product quality.

[0027] In use, this invention selects appropriate guide grooves 91, bending grooves 101, and clamping grooves 19 according to the specifications of the metal strip. After starting the device, the PLC controller controls the operation of each mechanism. First, the lifting drive cylinder 14 lowers the clamping mechanism to a suitable position, and the clamping drive motor 20 drives the forward and reverse lead screws 16 to rotate, causing the two clamping seats 18 to move towards each other, clamping the end of the metal strip in the clamping groove 19. Then, the translation drive cylinder 13 drives the movable mold 10 to move closer to the fixed mold 9, so that the metal strip is located between the guide groove 91 of the fixed mold 9 and the bending groove 101 of the movable mold 10. Next, the rotation drive motor 7 starts, driving the rotating seat 5 to rotate, while the movable mold 10 and the fixed mold 9 cooperate to bend the metal strip, forming a U-shaped buckle. After bending is completed, each mechanism resets, the U-shaped buckle is removed, and the next production cycle begins.
