[0024] As Figures 1-4 shown, a horn net forming and punching device includes an operating table 1, support columns 2 are symmetrically arranged at the bottom end of the operating table 1, a forming and punching die 3 is connected to the inner side of the operating table 1 by bolts, fixed connection columns 4 are symmetrically arranged on the top of the operating table 1, a connection top block 5 is fixedly connected to the top of the fixed connection column 4, hydraulic telescopic rods 6 are symmetrically arranged on the top of the connection top block 5, a punching tool is fixedly connected to the output end of the hydraulic telescopic rod 6 and is located inside the connection top block 5, fixed guide grooves 7 are symmetrically opened on the top of the operating table 1, and adjusting and limiting mechanisms 8 are symmetrically arranged inside the operating table 1.

[0025] The working principle of the above technical solution is as follows:

[0026] During the use process, place the speaker net plate on the top of the operating table 1, and let its end pass through between the forming punching die 3 and the connecting top block 5, so as to facilitate punching. At this time, adjust the adjusting and limiting mechanism 8 so that the adjusting and limiting mechanism 8 can limit and guide the edge of the speaker net plate, making the end of the speaker net plate move under the action of the winding device, driving the speaker net plate to move stably on the top of the operating table 1 and inside the adjusting and limiting mechanism 8, and then being able to stably perform forming punching treatment on the speaker net plate, with convenient operation.

[0027] In another embodiment, as Figure 3 shown, an auxiliary limiting mechanism 9 is provided at the top of the output end of the adjusting and limiting mechanism 8.

[0028] It is convenient for the auxiliary limiting mechanism 9 to be adjusted according to the thickness of the speaker net plate, so that the speaker net plate can be stably located inside the adjusting and limiting mechanism 8 for use.

[0029] In another embodiment, as Figure 2 shown, the adjusting and limiting mechanism 8 includes a bidirectional threaded rod 11 located inside the operating table 1. One end of the bidirectional threaded rod 11 is fixedly connected to an output motor 10, and the output motor 10 is fixedly connected to the operating table 1. The outer surface of the bidirectional threaded rod 11 is threadedly connected with a moving clamping mechanism 12.

[0030] It is convenient for the output motor 10 to drive the bidirectional threaded rod 11, so that the bidirectional threaded rod 11 can rotate stably. At this time, the moving clamping mechanism 12 can move stably on the outer surface of the bidirectional threaded rod 11, with convenient operation.

[0031] In another embodiment, as Figure 3 shown, the moving clamping mechanism 12 includes a moving base 13. The outer surface of the moving base 13 is slidably fitted with the inner side of the fixed guide groove 7. The top of the moving base 13 is fixedly connected to a connecting top frame 14. An active rotating roller 15 is movably provided at the inner bottom of the connecting top frame 14. A fixed through hole 16 is opened in the middle of the top of the connecting top frame 14, and guiding through holes 17 are symmetrically opened at the top of the connecting top frame 14.

[0032] It is convenient for the moving base 13 to move on the outer surface of the bidirectional threaded rod 11 and the inner side of the fixed guide groove 7 when the bidirectional threaded rod 11 rotates, driving the connecting top frame 14, the active rotating roller 15 and the auxiliary limiting mechanism 9 to move. The connecting top frame 14 can limit the edge of the speaker net plate, and the active rotating roller 15 can lift the bottom of the edge of the speaker net plate, facilitating the speaker net plate to move stably inside the connecting top frame 14, with convenient operation.

[0033] In another embodiment, asFigure 3 and Figure 4 As shown in Figure 4 , the auxiliary limiting mechanism 9 includes a connecting mounting frame 18 located at the top of the connecting top frame 14. An active threaded rod 19 is connected inside the connecting mounting frame 18 by threads. A rotating top plate 20 is fixedly connected to the top of the active threaded rod 19. A connecting bottom plate 21 is fixedly connected to the bottom end of the active threaded rod 19. A limiting connecting sleeve block 22 is movably sleeved on the outer side of the surface of the connecting bottom plate 21. A connecting bottom frame 23 is fixedly connected to the bottom of the limiting connecting sleeve block 22. A rotating guide roller 25 is movably arranged inside the bottom end of the connecting bottom frame 23. Connecting guide rods 24 are symmetrically arranged at the top of the connecting bottom frame 23.

[0034] When the edge of the speaker mesh plate is inside the connecting top frame 14, it is convenient to rotate the rotating top plate 20 to drive the active threaded rod 19 and the connecting bottom plate 21 to rotate, so that the active threaded rod 19 can move downward inside the connecting mounting frame 18, driving the connecting bottom plate 21, the limiting connecting sleeve block 22, the connecting bottom frame 23, the connecting guide rods 24 and the rotating guide roller 25 to move downward, so that the outer side of the surface of the rotating guide roller 25 can fit with the outer side of the surface of the speaker mesh plate, enabling the speaker mesh plate to move stably, and the operation is convenient.

[0035] In another embodiment, as Figure 3 shown, a fixed guide block 26 is fixedly connected to the inside of the connecting top frame 14, and a guide inclined surface is provided at the end of the fixed guide block 26.

[0036] When the end of the speaker mesh plate is clamped inside the connecting top frame 14, it is convenient for the fixed guide block 26 to guide the end of the speaker mesh plate, facilitating the installation of the speaker mesh plate.

[0037] In another embodiment, as Figure 3 shown, the outer side of the surface of the connecting guide rod 24 fits with the inside of the guide through hole 17, and the outer side of the surface of the limiting connecting sleeve block 22 fits with the inside of the fixed through hole 16.

[0038] It is convenient for the limiting connecting sleeve block 22 to be inside the fixed through hole 16. At the same time, when the connecting bottom frame 23 moves, the connecting guide rod 24 can move inside the guide through hole 17, and the operation is convenient.

[0039] Working principle of the utility model: During use, place the speaker mesh plate on the top of the operating table 1 and between the forming punching die 3 and the connecting top block 5. Then connect one end of the speaker mesh plate to the winding device. Next, the output motor 10 drives the bidirectional threaded rod 11 to rotate, enabling the moving base 13 to move on the outer surface of the bidirectional threaded rod 11 and inside the fixed guide groove 7, driving the connecting top frame 14, the movable rotating roller 15, and the auxiliary limiting mechanism 9 to move as a whole, so that the connecting top frame 14 can limit the edge of the speaker mesh plate. Then rotate the rotating top plate 20 to drive the movable threaded rod 19 and the connecting chassis 21 to rotate, causing the movable threaded rod 19 to move downward inside the connecting mounting frame 18, driving the connecting chassis 21, the limiting connecting sleeve block 22, the connecting bottom frame 23, the connecting guide rod 24, and the rotating guide roller 25 to move downward, enabling the connecting guide rod 24 to move inside the guide through hole 17. At the same time, the limiting connecting sleeve block 22 can disengage from the inside of the fixed through hole 16, and the outer surface of the rotating guide roller 25 is in contact with the surface of the speaker mesh plate, thereby being able to fully limit and guide the speaker mesh plate, enabling the speaker mesh plate to move stably, and further being able to stably perform forming and punching processing on the speaker mesh. The overall structure is simple, and the operation is convenient and fast.

[0040] The above embodiments only represent the specific implementation manners of the utility model, and the description is relatively specific and detailed, but it cannot be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
