Description

Technical Field

[0001] This utility model relates to the field of audio equipment manufacturing technology, and in particular to an audio equipment metal spring stamping device. Background Technology

[0002] Audio equipment has evolved from a simple audio playback tool into a core terminal product that integrates sound quality experience, intelligent control, and industrial design. The performance and precision of its internal core components directly determine the sound quality, stability, and lifespan of the equipment. As a key structural component for connecting circuits, conducting signals, and buffering vibrations, audio metal springs are widely used in core modules such as loudspeakers, tuning knobs, and interface terminals.

[0003] Currently, the processing of metal springs for audio equipment mainly relies on stamping technology. Metal springs are produced by stamping metal coils after using molds. After stamping, the metal coils need to be moved. However, during stamping, the molds squeeze the metal coils, which can easily cause the metal coils to stick to the lower mold. When moving the metal coils, friction occurs between the metal coils and the lower mold, and the metal coils are easily scratched by the lower mold. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the metal coil sticking to the lower die, friction occurring between the metal coil and the lower die during movement, and the metal coil being easily scratched by the lower die. Therefore, this invention proposes a metal spring stamping device for audio equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a metal spring stamping equipment for audio equipment, including a base frame, a support platform mounted on the upper end of the base frame, an unwinding mechanism on one side of the upper end of the support platform, a winding mechanism on the other side of the upper end of the support platform, a lifting mechanism fixedly connected to the upper end of the support platform, an upper die connected to the lifting mechanism, a lower die mounted on the upper end of the support platform, a discharge port on the lower die, grooves on both sides of the upper end of the lower die, a movable frame slidably connected in each groove, the bottom end of each movable frame connected to the groove by a spring, and a rotating roller rotatably connected to each movable frame, the upper end of the rotating roller extending out of the groove.

[0006] Preferably, the lifting mechanism includes a mounting frame, which is fixedly connected to the upper end of the support platform. A hydraulic cylinder is mounted on the mounting frame, and the telescopic end of the hydraulic cylinder is connected to the upper mold.

[0007] Preferably, connecting plates are fixedly connected to both sides of the upper end of the upper mold, and two parallel sliding brackets are installed on the mounting frame, with one end of each connecting plate slidably connected to the sliding bracket.

[0008] Preferably, a collection box is provided on the base frame below the discharge port.

[0009] Preferably, the springs are provided in a plurality of them and are evenly distributed along the length of the movable frame.

[0010] Preferably, anti-deviation mechanisms are installed on both sides of the upper end of the support platform. The anti-deviation mechanism includes a fixing frame, which is fixedly connected to the upper end of the support platform. Groove seats are fixedly connected to both sides of the upper end of the fixing frame.

[0011] Preferably, each of the groove seats is provided with an anti-wear pad.

[0012] Preferably, the anti-wear pad is an abrasion-resistant rubber pad.

[0013] The beneficial effects of the audio metal spring stamping equipment proposed in this utility model are as follows: After the stamping process is completed, the upper die moves upward and resets. Under the action of the spring force, the movable frame moves upward and resets. The movable frame drives the rotating roller to move upward and reset. After the rotating roller resets, it pushes the metal coil to move, so that a gap is created between the metal coil and the upper end of the lower die, which prevents the metal coil from sticking to the lower die and thus prevents the metal coil from being scratched by the lower die.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-4 A metal spring stamping device for audio equipment includes a base frame 1, a support platform 2 installed on the upper end of the base frame 1, an unwinding mechanism 3 on one side of the upper end of the support platform 2, a winding mechanism 4 on the other side of the upper end of the support platform 2, a lifting mechanism 5 fixedly connected to the upper end of the support platform 2, an upper die 6 connected to the lifting mechanism 5, a lower die 7 installed on the upper end of the support platform 2, the lower die 7 cooperates with the upper die 6, a discharge port 8 is opened on the lower die 7, a collection box 9 is provided on the base frame 1 below the discharge port 8, grooves 10 are opened on both sides of the upper end of the lower die 7, a movable frame 11 is slidably connected in each groove 10, the bottom end of each movable frame 11 is connected to the groove 10 by a spring 12, several springs 12 are provided and evenly distributed along the length direction of the movable frame 11, a rotating roller 13 is rotatably connected to each movable frame 11, the upper end of the rotating roller 13 extends out of the groove 10.

[0018] Work process: The metal coil is installed on the unwinding mechanism 3, and one end of the metal coil is connected to the winding mechanism 4. After the lifting mechanism 5 is started, it drives the upper die 6 to move down a set distance and then resets. After the upper die 6 moves down a set distance, it cooperates with the lower die 7 to punch the metal coil. The debris generated by the punching passes through the discharge port 8 and falls into the collection box 9. During stamping, the upper die 6 presses the rotating roller 13 downward, causing the rotating roller 13 to retract into the groove 10. During the retraction of the rotating roller 13, the movable frame 11 moves downward. After the movable frame 11 moves downward, it presses the spring 12. The spring 12 generates elastic force after being pressed. After the stamping is completed, the upper die 6 moves upward to reset. Under the action of the elastic force of the spring 12, the movable frame 11 moves upward to reset. The movable frame 11 drives the rotating roller 13 to move upward to reset. After the rotating roller 13 resets, it pushes the metal coil to move, so that a gap is generated between the metal coil and the upper end of the lower die 7, so as to avoid the metal coil from sticking to the lower die 7 and thus avoid the metal coil being scratched by the lower die 7.

[0019] Example 2: During the vertical movement of the upper die 6, the upper die 6 is prone to wobbling, thereby reducing the stamping effect. (Refer to...) Figure 2As another preferred embodiment of this utility model, the difference from embodiment 1 is that the lifting mechanism 5 includes a mounting frame 51, the mounting frame 51 is fixedly connected to the upper end of the support platform 2, a hydraulic cylinder 52 is mounted on the mounting frame 51, the telescopic end of the hydraulic cylinder 52 is connected to the upper mold 6, and connecting plates 53 are fixedly connected to both sides of the upper end of the upper mold 6. Two parallel sliding groove frames 54 are mounted on the mounting frame 51, and one end of each connecting plate 53 is slidably connected to the sliding groove frame 54. After the hydraulic cylinder 52 is started, it drives the upper mold 6 to move. The upper mold 6 drives the connecting plate 53 to move. One end of the connecting plate 53 slides on the slide frame 54. With the cooperation of the connecting plate 53 and the slide frame 54, the upper mold 6 is guided and limited, so that the upper mold 6 moves smoothly in the vertical direction.

[0020] Example 3: Metal coils are prone to shifting during movement, refer to... Figure 5 As another preferred embodiment of the present invention, the difference from embodiment 1 is that anti-offset mechanism 14 is installed on both sides of the upper end of the support platform 2. The anti-offset mechanism 14 includes a fixing frame 141, which is fixedly connected to the upper end of the support platform 2. Groove seats 142 are fixedly connected to both sides of the upper end of the fixing frame 141. Each groove seat 142 is provided with an anti-wear pad 143, which is a wear-resistant rubber pad. The fixing bracket 141 fixes two groove seats 142. The metal coil passes through the two groove seats 142. The groove seats 142 contact the metal coil through the anti-wear pad 143 to limit the metal coil and prevent the metal coil from shifting.
