DETAILED DESCRIPTION

[0039] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0040] Embodiment 1: A punching device for an audio component for audio production, such as Figure 1-Figure 6 As shown, it includes a support base 1, a cylinder 11 is installed on the support base 1, a punching head 13 is fixedly connected to the lower end of the telescopic rod 12 of the cylinder 11, the punching head 13 is divided into a cubic upper part and a hollow cylindrical lower part, the cubic upper part of the punching head 13 is fixedly connected to the lower end of the telescopic rod 12 of the cylinder 11, a pressure rod 21 is slidably connected to the support base 1, a first compression spring 2 is connected between the pressure rod 21 and the support base 1, an extrusion piece 22 is fixedly connected to the lower side of the pressure rod 21, and a rotary spring 2 is rotatably connected inside the punching head 13. The movable member 23, the lower end of the rotating member 23 is located in the lower part of the hollow cylinder of the punching head 13, the extrusion member 22 is slidably and rotatably connected with the punching head 13, the rotating member 23 has a threaded groove, the punching head 13 is fixedly connected with a limiting member 24, the lower end of the middle part of the limiting member 24 is located in the threaded groove of the rotating member 23, the limiting member 24 is in contact with the rotating member 23, and a second compression spring 25 is connected between the punching head 13 and the extrusion member 22, and the elastic coefficient of the first compression spring 2 is greater than the elastic coefficient of the second compression spring 25.

[0041] When using the device to punch holes in the speaker net, first place the unpunched speaker net on the support seat 1 directly below the punching head 13, start the cylinder 11 to extend the telescopic rod 12 of the cylinder 11, and the extension of the telescopic rod 12 of the cylinder 11 will drive the punching head 13 to move downward to contact the speaker net, and the punching head 13 continues to press down to punch holes in the speaker net. When the punching head 13 moves to the lowest point, the cylinder 11 is controlled to retract the telescopic rod 12 of the cylinder 11, and the punching head 13 moves upward to separate from the speaker net. When the punching head 13 moves back to the initial position, the cylinder 11 is closed to complete the punching of the speaker net. During the extension of the telescopic rod 12 of the cylinder 11, the downward movement of the punching head 13 will drive the limit member 24, the extrusion member 22 and the rotating member 23 to move downward, and the first compression spring 2 and the second compression spring 25 are stretched. Since the elastic coefficient of the first compression spring 2 is greater than that of the second compression spring 25, and the stretched length of the first compression spring 2 is greater than the second compression spring 25, so the extruded piece 22 will move upward relative to the punching head 13, and the extruded piece 22 drives the rotating piece 23 to rotate, so that the rotating piece 23 rotates in the lower part of the hollow cylinder of the punching head 13; when the punching head 13 moves to the lowest point and starts to move upward, the upward movement of the punching head 13 will drive the limit piece 24, the extruded piece 22 and the rotating piece 23 to move upward, and the first compression spring 2 and the second compression spring 25 begin to reset from the stretched state. Since the elastic coefficient of the first compression spring 2 is greater than the elastic coefficient of the second compression spring 25, the extruded piece 22 will move downward back to its original position relative to the punching head 13, thereby driving the rotating piece 23 to rotate in the opposite direction. The rotating piece 23 rotates in the lower part of the hollow cylinder of the punching head 13, which can prevent the stamping waste sheet from sticking to the bottom of the hollow cylinder of the punching head 13.

[0042] like Figure 7-Figure 8 As shown, it also includes a protruding rod 3, both sides of the extrusion piece 22 are fixedly connected with the protruding rod 3, both sides of the punching head 13 are fixedly connected with the sliding rail 31, the sliding rail 31 is slidably connected with a knocking rod 32, and a tension spring 33 is connected between the knocking rod 32 and the sliding rail 31. When the extrusion piece 22 and the punching head 13 move relative to each other, the protruding rod 3 and the knocking rod 32 are squeezed and contacted.

[0043] When the extrusion piece 22 and the punching head 13 approach each other or move away from each other, the knocking rod 32 contacts the protruding rod 3, and the protruding rod 3 squeezes the knocking rod 32 so that the knocking rod 32 slides outward on the slide rail 31. The tension spring 33 is stretched, and the knocking rod 32 is no longer squeezed by the protrusion on the protruding rod 3. Due to the reset effect of the tension spring 33, the knocking rod 32 slides inward on the slide rail 31 and knocks the protruding rod 3. The protruding rod 3 is knocked, and the extrusion piece 22, the punching head 13 and the rotating piece 23 will vibrate and shake off the stamping waste sheets attached to the punching head 13.

[0044] Embodiment 2: Based on Embodiment 1, a punching device for an audio component for audio production, such as Figure 9-11As shown, it also includes a first rack 4, the first rack 4 is fixedly connected to the rear side of the punching head 13, first screws 41 are rotatably connected to both sides of the support seat 1, first guide rods 42 are fixedly connected to both sides of the support seat 1, a first push plate 43 is slidably connected to the first guide rod 42, a rotating plate 431 is rotatably connected to the lower side of the first push plate 43, the front side of the rotating plate 431 is an inclined surface, the rotating direction of the rotating plate 431 is backward, the first screw 41 is threadedly connected to the first push plate 43, a flat gear 44 is fixedly connected to the rear end of the first screw 41, and the first rack 4 is meshed with the flat gear 44.

[0045] After the punching of the current audio component is completed, when the cylinder 11 drives the punching head 13 to move upward, the first rack 4 also moves upward, thereby driving the flat gear 44 and the first screw 41 to rotate, and the first screw 41 rotates to drive the first push plate 43 and the rotating plate 431 to move backward. The first push plate 43 and the rotating plate 431 move backward to push the punched audio component backward. In the process of the first push plate 43 and the rotating plate 431 moving backward to the final position, the next audio component that needs to be punched is placed; when the punching head 13 moves downward to punch the next audio component that needs to be punched, the first rack 4 also moves downward, thereby driving the flat gear 44 and the first screw 41 to rotate in the opposite direction, and the first screw 41 rotates to drive the first push plate 43 and the rotating plate 431 to move forward. The rotating plate 431 moves forward to contact the audio component. The rotating plate 431 is squeezed by the audio component and rotates upward. When the rotating plate 431 moves forward and no longer contacts the audio component, due to the action of gravity, the rotating plate 431 rotates downward back to the initial state.

[0046] like Figure 12-13 As shown, it also includes a second guide rod 51, the second guide rod 51 is fixedly connected to the support seat 1, the second guide rod 51 is slidably connected to the support frame 5, the first spring 52 is wound on the second guide rod 51, the two ends of the first spring 52 are respectively connected to the support seat 1 and the support frame 5, the second push plate 53 is fixedly connected to the bottom of the first push plate 43, and the second push plate 53 is in extrusion contact with the support frame 5; it also includes a first limit plate 54, the first limit plate 54 is slidably connected to the front and rear sides of the support frame 5, and a second spring 55 is connected between the first limit plate 54 and the support frame 5.

[0047] When the first push plate 43 is in the frontmost position, the first limiting plate 54 is located at the front and rear sides of the audio component to limit the audio component; when the first push plate 43 moves backward from the frontmost position, the second push plate 53 moves backward accordingly to squeeze the support frame 5, so that the support frame 5 moves downward, the first spring 52 is compressed, and the first limiting plate 54 no longer limits the audio component; the first push plate 43 and the rotating plate 431 push the punched audio component backward; when the first push plate 43 moves to the final position, the second push plate 53 still squeezes the support frame 5; when the first push plate 43 moves to the frontmost position, the second push plate 53 no longer squeezes the support frame 5; due to the resetting effect of the first spring 52, the support frame 5 moves upward, and the first limiting plate 54 limits the audio component again.

[0048] Embodiment 3: Based on Embodiment 2, a punching device for an audio component for audio production, such as Figure 14-15 As shown, it also includes a clamping block 64, a second rack 6 is fixedly connected to the lower side of the second push plate 53, a rotating rod 61 is rotatably connected to the support seat 1, and two inner and outer one-way gears 62 are fixedly connected at both ends of the rotating rod 61, the outer one-way gear 62 is meshed with the lower rack part of the second rack 6, and the inner one-way gear 62 is meshed with the upper rack part of the second rack 6, and a clamping block 64 is rotatably connected to the rotating rod 61, and a torsion spring 63 is fixedly connected between the clamping block 64 and the rotating rod 61, and the transmission direction of the outer one-way gear 62 is opposite to the transmission direction of the inner one-way gear 62.

[0049] When the second push plate 53 moves backward from the frontmost position, it drives the second rack 6 to move backward, driving the outer one-way gear 62 to rotate counterclockwise from right to left, thereby driving the rotating rod 61, the torsion spring 63 and the clamping block 64 to rotate counterclockwise from right to left, the torsion spring 63 is twisted by force, and the clamping block 64 rotates forward and no longer clamps the audio component; when the second push plate 53 moves backward to the upper side of the second rack 6 and meshes with the inner one-way gear 62, it drives the inner one-way gear 62 from right to left When viewed from the clockwise direction, the rotating rod 61, the torsion spring 63 and the clamping block 64 are driven to rotate clockwise from right to left. The torsion spring 63 is twisted by the force, and the clamping block 64 rotates backward to clamp the audio component. When the second push plate 53 moves forward from the last position, the inner one-way gear 62 can only drive the rotating rod 61 to rotate clockwise from right to left, and the outer one-way gear 62 can only drive the rotating rod 61 to rotate counterclockwise from right to left. Therefore, the rotating rod 61 will not rotate during this process.

[0050] like Figure 15-16As shown, it also includes a first fixed block 67, the first fixed block 67 is fixedly connected to the support seat 1, the first fixed block 67 is slidably connected to the third guide rod 65, the third guide rod 65 is wound with a third spring 66, both ends of the third spring 66 are connected to the third guide rod 65 and the first fixed block 67, the end of the third guide rod 65 that contacts the rotating rod 61 is spherical, the rotating rod 61 is provided with a bayonet, and the end of the third guide rod 65 that contacts the rotating rod 61 is snapped into the bayonet on the rotating rod 61.

[0051] When the second rack 6 moves to the point where it is no longer meshed with the inner and outer one-way gears 62, the third guide rod 65 can fix the rotating rod 61, the torsion spring 63 and the block 64 to prevent the rotating rod 61 and the block 64 from rotating back to their original positions due to the reset action of the torsion spring 63. The specific operation is as follows: when the second push plate 53 is at the frontmost position, the third guide rod 65 is clamped on the rotating rod 61. When the outer one-way gear 62 rotates, the third guide rod 65 is no longer clamped on the rotating rod 61, and the third spring 66 is compressed. During the rotation of the rotating rod 61, the third guide rod 65 is close to the rotating rod 61. When the outer one-way gear 62 is no longer meshed with the lower side of the second rack 6, the rotating rod 61 rotates until the bayonet is facing the third guide rod 65. The restoring action of the spring 66 drives the third guide rod 65 to move backward and snap into the rotating rod 61, fixing the rotating rod 61, the torsion spring 63 and the block 64; when the second push plate 53 moves backward to the upper side of the second rack 6 and meshes with the inner one-way gear 62, the third guide rod 65 is no longer snapped into the rotating rod 61, and the third spring 66 is compressed. During the rotation of the rotating rod 61, the third guide rod 65 is close to the rotating rod 61. When the second push plate 53 moves backward to the final position, the rotating rod 61 rotates until the snap-in is opposite to the third guide rod 65. Due to the restoring action of the third spring 66, the third guide rod 65 is driven to move backward and snap into the rotating rod 61, fixing the rotating rod 61, the torsion spring 63 and the block 64.

[0052] like Fig.17 As shown, it also includes a second limiting plate 7, two second limiting plates 7 are slidably connected to the front side of the support seat 1, a second fixing block 71 is fixedly connected to the front side of the support seat 1, a second screw rod 72 is rotatably connected to the second fixing block 71, the second screw rod 72 is a bidirectional screw rod, a handle 73 is fixedly connected to the right side of the second screw rod 72, and the two second limiting plates 7 are respectively threadedly connected to the left and right ends of the second screw rod 72.

[0053] Turn the handle 73 to adjust the distance between the two second limiting plates 7, place the unpunched audio component into the two second limiting plates 7, turn the handle 73, the handle 73 drives the second screw 72 to rotate, and the rotation of the second screw 72 drives the second limiting plates 7 to move. When the second limiting plates 7 on both sides move to fit exactly with the unpunched audio component, push the unpunched audio component backwards onto the support seat 1. This operation can ensure that the unpunched audio component is located directly under the punching head 13, thereby improving the punching accuracy.

[0054] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
