[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 This utility model provides a wire clamp bending fixture, including Punch 1, the upper end of which is connected to the die shank of the stamping press; Die 4 is located directly below punch 1 and is configured in a split structure. A sliding assembly is connected to the surface of the worktable 8, and the lower part of the die 4 is connected to the sliding assembly; The sliding component is used to drive the die 4 to move in a straight line towards each other or away from each other; Positioning plate 2, the bottom of which is connected to the top of the die 4, the positioning plate 2 is configured in a half-and-half structure, and the shape of the positioning plate 2 is adapted to the top shape of the die 4.

[0014] The device comprises: a punch, which is a columnar structure with a connecting part (such as an inner hole or flange) at its upper end adapted to the die handle of the stamping press. The connecting part is detachably fixed to the die handle of the stamping press (e.g., by bolt locking or conical surface engagement) to ensure that the punch is coaxial with the power output shaft of the stamping press and to prevent the punch from shifting during stamping; the lower contour of the punch is adapted to the open semi-circular structure of the wire clip and is used to apply bending pressure to the sheet metal; a die, which is located directly below the punch, and the central axis of the die coincides with the central axis of the punch; the die has a split structure, specifically composed of two symmetrical die units, which, when assembled, form an open semi-circular cavity that matches the shape of the wire clip, and the inner wall curvature of the cavity is consistent with the design curvature of the wire clip; and a sliding assembly, which is fixedly connected to the worktable surface by bolts. The lower part of the die (the bottom of each die unit) is provided with a slider, which slides against the sliding assembly. The sliding assembly allows the two die units to move synchronously in opposite directions or away in a straight line (opening the cavity for part removal). The direction of movement of the sliding assembly is parallel to the axis of symmetry of the die, ensuring precise alignment when the cavity is assembled. The positioning plate has a split structure, corresponding one-to-one with the split structure of the die (i.e., two positioning plate units match two die units respectively). The bottom of each positioning plate unit is detachably fixed to the top of the corresponding die unit by screws 3 or positioning pins 5. The overall shape of the positioning plate unit is perfectly matched to the top shape of the die unit (e.g., if the top of the die unit is arc-shaped, the bottom of the positioning plate unit has a corresponding arc-shaped groove), ensuring synchronous movement between the positioning plate and the die, avoiding positioning deviations caused by relative displacement. The upper surface of the positioning plate is used to support the aluminum alloy sheet to be processed and remains parallel to the lower surface of the punch, ensuring that the stamping pressure is evenly transmitted to the sheet.

[0015] In some embodiments, a groove adapted to the workpiece is provided on the upper surface of the positioning plate 2, and the shape of the groove is adapted to the shape of the positioning plate 2.

[0016] The upper surface of the positioning plate (the upper surface of each positioning plate unit) is provided with a groove that matches the contour of the workpiece to be processed. The overall shape of the groove matches the half-and-half structure of the positioning plate (that is, the grooves of the two positioning plate units are joined together to form a complete open semi-circular groove). The depth of the groove matches the thickness of the aluminum alloy sheet to be processed, ensuring that the sheet can be embedded in the groove without loosening. Guide slopes are provided at both ends of the groove to facilitate the quick placement of the sheet into the groove, while further limiting the left and right displacement of the sheet, improving positioning efficiency and accuracy.

[0017] In some embodiments, the sliding assembly includes: an electrically telescopic rod 6 and a slide rail 7; The slide rail 7 is connected to the surface of the worktable 8. There are two slide rails 7, which are arranged in parallel at intervals. The side of the concave mold 4 is provided with a long groove notch, and the bottom of the long groove notch is connected to the output end of the electric telescopic rod 6. The bottom two sides of the groove are respectively slidably connected to one of the guide rails; The bottom of the electric telescopic rod 6 is provided with a support plate, and the slide rails 7 on the same side of the support plate are connected.

[0018] The slide rail is fixedly connected to the surface of the worktable by bolts. The slide rail is a linear ball bearing slide rail, and its length direction is parallel to the axis of symmetry of the die cavity. Two slide rails are provided, and the two slide rails are arranged in parallel with a gap (the gap is adapted to the width of the die cavity unit) to ensure the force balance during the movement of the die cavity. Each die cavity unit has a long slot notch on its side (the side facing away from the cavity). The extension direction of the long slot notch is consistent with the length direction of the slide rail. The bottom of the long slot notch is fixedly connected to the output end of the electric telescopic rod by a coupling or bolts. Two electric telescopic rods are provided, each corresponding to one of the two die cavity units, and the two electric telescopic rods are driven by... The same controller provides synchronous control (e.g., using a PLC controller) to ensure that the relative speeds and strokes of the two die units are completely consistent, preventing misalignment during cavity assembly. The bottom sides of each die unit are bolted to sliders on a slide rail, with a clearance of ≤0.05mm between the sliders and the slide rail, ensuring smooth and uninterrupted die movement. A support plate is fixedly connected to the bottom of the electric telescopic rod. The support plate is made of 8-12mm thick steel, and both sides are bolted to the ends of the slide rails on the same side, forming a stable frame structure that prevents vibration during operation and improves drive stability.

[0019] In some embodiments, the lower end contour of the punch 1 and the contour of the groove are both rounded.

[0020] The lower contour of the punch (i.e., the edge in contact with the sheet metal) is rounded with a radius of R3-R5mm. The rounded corner surface is ground and polished to prevent the sharp edge from scratching the sheet metal surface during stamping, and to reduce stress concentration when the sheet metal is bent, thus reducing the risk of wire clip cracking. The contour of the positioning plate groove (including the inner wall edge of the groove and the connection between the groove and the upper surface of the positioning plate) is rounded to match the lower corner of the punch, ensuring that the edge of the sheet metal is not scratched by the sharp part of the groove when it is bent in the groove, and ensuring that the edge contour of the wire clip after forming is smooth and meets the design requirements.

[0021] In some embodiments, the worktable 8 directly below the die 4 has a hollow structure, and a storage box is provided directly below the die 4.

[0022] The workbench has a frame structure with a hollow opening directly below the cavity formed by the assembly of two die units. The hollow opening is rectangular, with both its length and width exceeding the size of the cavity after assembly, ensuring that the wire clips can fall smoothly through the opening after forming. The storage box is located directly below the hollow opening of the workbench. The storage box is made of plastic or metal and has an open top, the size of which matches the size of the hollow opening of the workbench. The bottom of the storage box is lined with a sponge cushioning pad to prevent the wire clips from being deformed or scratched due to impact when falling. One side of the storage box has a drawer-type structure or an openable door for easy batch retrieval of collected wire clips. The bottom of the storage box is fixed to the ground by a support with adjustable height to accommodate different operators' retrieval habits, while ensuring precise alignment between the storage box and the hollow opening of the workbench without any offset.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
