Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically to a side-welded copper sheet stamping structure for automatic positioning of coiled material. Background Technology

[0002] Coil material refers to raw materials supplied in the form of coiled copper strips. During the stamping process, the copper strip is guided and fixed to a set position within the die. The strip is automatically fed into the core of a stamping structure, such as a stamping die. At different "workstations" within the die, the copper strip is processed step by step: first, it is punched; then, at a specific workstation, the die's "robotic arm" precisely bends or presses a portion of the strip into a specific angle or shape. This shaped portion is the key surface designed for side welding. Ultimately, a complete copper sheet part with side welding features is stamped out or separated from the strip.

[0003] Existing coiled copper strips lack guiding equipment during transport, relying on manual adjustments by workers to position them on the stamping worktable. However, this method is prone to positioning inaccuracies, leading to product scrap. The copper strip is also prone to lateral swaying or longitudinal movement during feeding, and manual guidance and adjustment cannot accurately stop it at the center of the mold station, resulting in reduced raw material utilization and failing to meet production requirements. Therefore, a side-welded copper sheet stamping structure with automatic coil positioning is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a side-welded copper sheet stamping structure for automatic positioning of coiled material. It has advantages such as precise positioning and strong adaptability, and solves the problem of lack of guiding equipment when conveying coiled copper strips.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side-welded copper sheet stamping structure for automatic positioning of coiled material, including a worktable and a stamping structure disposed above the worktable, wherein the stamping structure consists of a hydraulic telescopic rod and a stamping block fixed to the output end of the hydraulic telescopic rod;

[0006] A support frame is fixed to the bottom side of the worktable, and a roller and a driving mechanism for driving the roller are provided on the support frame. A guiding structure for guiding the copper strip is provided on the bottom side of the worktable.

[0007] The guiding structure includes a dual-axis electric telescopic rod. A first connecting rod is fixed on each of the two output shafts of the dual-axis electric telescopic rod. A second connecting rod is fixed at one end of each of the two first connecting rods, and a guide wheel is fixed at the other end of each of the two second connecting rods. The two guide wheels are symmetrically distributed.

[0008] Furthermore, the end of the roller is fixed with an installation shaft that is rotatably connected to the support frame. There are two support frames and two rollers, and the two support frames are symmetrically distributed.

[0009] Furthermore, a reinforcing beam is welded between the two support frames, and a mounting bracket is fixed to the outside of the reinforcing beam.

[0022] 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.

[0023] Please see Figures 1 to 4 The side-welded copper sheet stamping structure for automatic positioning of coiled material in this embodiment includes a workbench 1 and a stamping structure disposed above the workbench 1. The stamping structure consists of a hydraulic telescopic rod 4 and a stamping block 41 fixed to the output end of the hydraulic telescopic rod 4. A support frame 2 is fixed to the bottom side of the workbench 1, and a reinforcing beam is welded between the two support frames 2. A mounting frame 3 is fixed to the outside of the reinforcing beam. The hydraulic telescopic rod 4 is fixed to the outer wall of the mounting frame 3. A stamping hole 11 is opened inside the workbench 1, and the stamping block 41 is located directly above the stamping hole 11. A collection bin 8 is bolted to the lower surface of the workbench 1, and the collection bin 8 is connected to the stamping hole 11. The collection bin 8 is conical in shape. Through the direct connection between the conical collection bin 8 and the stamping hole 11, waste material automatically slides down, reducing cleaning time. The synchronization component ensures that the two rollers 5 rotate at the same speed, preventing copper strip misalignment or stretching deformation.

[0024] Specifically, the end of the roller 5 is fixed with a mounting shaft 51 that is rotatably connected to the support frame 2. There are two support frames 2 and two rollers 5, and the two support frames 2 are symmetrically distributed. One roller 5 is used for unwinding and the other for winding.

[0025] To achieve copper strip conveying, the support frame 2 is equipped with rollers 5 and a drive mechanism 6 for driving the rollers 5. The drive mechanism 6 includes a drive motor 61, a worm gear 62, a worm wheel 63, and a synchronization assembly. The worm gear 62 is fixed to the output shaft of the drive motor 61, and the worm wheel 63 is fixed to the outer surface of the mounting shaft 51. The worm gear 62 meshes with the worm wheel 63. Specifically, the synchronization assembly consists of two synchronization pulleys 64 and a synchronization belt 65 installed between the synchronization pulleys 64. The two synchronization pulleys 64 are of different sizes and are respectively fixed to the outer surfaces of the two mounting shafts 51. The drive motor 61 is fixed to the outer wall of the front support frame 2. The design of the synchronization pulleys 64 of different sizes in the synchronization assembly achieves different transmission ratios. By replacing the synchronization pulleys 64 of different sizes, the rotational speed relationship between the two rollers 5 can be adjusted, thereby adapting to the conveying needs of copper strips of different materials and thicknesses, improving the versatility of the equipment.

[0026] It should be noted that the synchronous pulley 64 and the synchronous belt 65 can be toothed to improve the transmission ratio and prevent slippage between them. The worm 62 is fixed to the output shaft of the drive motor 61, and the worm wheel 63 is fixed to the outer surface of the mounting shaft 51; the two mesh together for transmission. This transmission method features a large transmission ratio and a compact structure, significantly reducing the size of the drive mechanism 6 and making the entire structure more compact. The worm 62 and worm wheel 63 transmission also has self-locking properties. When the lead angle of the worm 62 is less than the equivalent friction angle between the meshing teeth, the mechanism is self-locking, achieving reverse self-locking. This means that only the worm 62 can drive the worm wheel 63, and not the other way around. This characteristic is particularly important when the equipment stops or is powered off, effectively preventing the roller 5 from reversing due to inertia or external force, avoiding copper belt loosening or equipment damage, and improving equipment safety.

[0027] To guide the copper strip, a guiding structure 7 is provided on the bottom side of the worktable 1. The guiding structure 7 includes a dual-axis electric telescopic rod 71. A first connecting rod 72 is fixed to each of the two output shafts of the dual-axis electric telescopic rod 71. A second connecting rod 73 is fixed to one end of each of the two first connecting rods 72, and a guide wheel 74 is fixed to the other end of each second connecting rod 73. The two guide wheels 74 are symmetrically distributed. Through precise control of the dual-axis electric telescopic rod 71, the two guide wheels 74 can symmetrically clamp the edge of the copper strip, achieving automatic centering and positioning of the copper strip. This ensures that the copper strip is always in the correct position during conveying, improving the accuracy and consistency of stamping. The first connecting rod 72 and the second connecting rod 73 are both L-shaped. The dual-axis electric telescopic rod 71 is fixed to the bottom side of the worktable 1, and there are two guiding structures 7. A protective pad is installed on the outer surface of the guide wheels 74.

[0028] The working principle of the above embodiments is as follows:

[0029] First, the copper strip coil is transported through roller 5. The drive motor 61 in the drive mechanism 6 drives the worm 62 to rotate, and the power is transmitted to the mounting shaft 51 through the worm wheel 63, which drives the roller 5 to rotate. The synchronization component ensures that the two rollers 5 rotate synchronously, so as to realize the smooth transport of copper strip.

[0030] The guiding structure 7 drives the first connecting rod 72 and the second connecting rod 73 through the dual-axis electric telescopic rod 71, which drives the two guide wheels 74 to symmetrically clamp the edge of the copper strip to achieve automatic centering and positioning. The hydraulic telescopic rod 4 drives the stamping block 41 to press down, passing through the stamping hole 11 of the worktable 1, and stamping the positioned copper strip to form a side-welded copper sheet. The material generated by stamping falls into the conical collection bin 8 through the stamping hole 11 for centralized recycling.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
