The cutting device for conductive sponge production of the utility model can contact the top of conductive sponge by pressing plate before cutting the conductive sponge, and the top of conductive sponge is pressed tightly and fixed, and the cutting position is retained, so that displacement of conductive sponge is avoided during cutting process, poor cutting effect is caused, and cutting efficiency is affected.

[0004] Although the above-mentioned patent can avoid displacement of conductive sponge during cutting process, cause poor cutting effect and affect cutting efficiency, it lacks effective mechanism to tension sponge surface to both sides, so that the sponge in cutting area cannot maintain flat state, and the sponge is prone to local fluctuation or wrinkle during cutting process, the cutting mechanism is difficult to accurately cut according to preset path, the cutting edge is uneven, and the appearance quality and actual use effect of product are seriously affected. SUMMARY

[0005] In view of the above prior art, the technical problem to be solved by the utility model is that there is lack of effective mechanism to tension sponge surface to both sides, so that the sponge is prone to fluctuation and wrinkle during cutting, the cutting mechanism is difficult to accurately cut, the cutting edge is uneven, and the appearance quality of product is seriously affected.

[0006] To address the aforementioned problems, this utility model provides a cutting device for producing automotive sound-absorbing sponge, comprising a workbench with a mounting frame fixedly connected thereon, and a frame lifted and connected to the mounting frame. The frame has pressure plates on both sides below it, and connecting rods are rotatably connected to both ends of the upper surface of the pressure plates. A rotating shaft is fixedly connected to the end of each connecting rod away from the pressure plate, and a rotating seat is rotatably connected to the rotating shaft. The rotating seat is fixedly connected to the frame, and limit blocks are fixedly connected to both ends of the rotating shaft. A torsion spring is sleeved on the rotating shaft, with one end fixedly connected to the limit block and the other end fixedly connected to the rotating seat. A cutting mechanism is connected to the frame and used to cut the sound-absorbing sponge placed on the workbench.

[0007] In the aforementioned cutting equipment for automotive sound-absorbing foam production, the pressure plate tensions the foam to make the cutting area flat, which helps the cutting mechanism to cut accurately and ensures the cutting edge and product quality. At the same time, the torsion spring force is used to stabilize the pressure of the pressure plate on the foam, ensuring stability during foam cutting, improving cutting accuracy, and reducing scrap rate.

[0008] As a further improvement of this application, the cutting mechanism includes a fixed box and a cutting blade. The cutting blade is inserted into the fixed box and is detachably connected to the fixed box. The fixed box is lifted and connected to the frame. A cutting groove for use with the cutting blade is provided on the worktable.

[0009] As a further improvement to this application, a cylinder is fixedly connected to the frame, and the fixed box is fixedly connected to the output end of the cylinder.

[0010] As a further improvement of this application, the fixing box is symmetrically threaded with fixing bolts on both sides, and locking holes are opened on both sides of the cutting blade, with the fixing bolts inserted into the locking holes.

[0011] As another improvement of this application, an electric telescopic rod is symmetrically fixedly connected to the mounting bracket, and the frame is fixedly connected to the output end of the electric telescopic rod.

[0012] As a further improvement to this application, the lower end face of the pressure plate is provided with anti-slip texture.

[0013] In summary, this application uses pressure plates to tension the sponge surface on both sides, keeping the sponge flat in the cutting area. This allows the cutting mechanism to cut more precisely, ensuring the neatness of the cut edges and product quality. At the same time, the elastic force generated by the deformation of the torsion spring ensures that the pressure plates can continuously and stably apply pressure to the sponge, firmly fixing the sponge to the worktable. This effectively ensures the stability of the sponge during cutting, thereby improving cutting accuracy and reducing waste. Attached Figure Description

[0026] Firstly, the automobile sound-absorbing sponge is placed on the workbench 1, then the electric telescopic rod 3 is started, the output end of the electric telescopic rod 3 moves downward, drives the frame 2 fixedly connected thereto to slowly descend, when the frame 2 descends, the pressing plates 206 on the two sides thereof gradually approach the sound-absorbing sponge, when the pressing plates 206 contact the surface of the sound-absorbing sponge, the pressing plates 206 rotate around the rotating shaft 203 by means of the connecting rods 202, in the rotating process, the pressing plates 206 are tensioned to the two sides of the sponge surface, the sponge in the cutting area is kept flat, the cutting mechanism can cut more accurately, the neatness of the cutting edge and the product quality are ensured, at the same time, the torsional spring 205 sleeved on the rotating shaft 203 is elastically deformed, the elastic force generated by the deformation is utilized to ensure that the pressing plates 206 can continuously and stably press the sponge, the sponge is firmly fixed on the workbench 1, the stability of the sponge during cutting is effectively ensured, the cutting precision is improved, and the generation of waste products is reduced, after cutting, the electric telescopic rod 3 is started again, the output end thereof is raised, drives the frame 2 and the pressing plates 206 to move away from the sponge, so that the cut sponge is conveniently taken out and the new material to be cut is placed.

[0027] Figure 1 、 Figure 2 、 Figure 5 It is shown that the cutting mechanism comprises a fixed box 4 and a cutting knife 401, the cutting knife 401 is inserted into the fixed box 4 and detachably connected with the fixed box 4, the fixed box 4 is connected with the frame 2 in a lifting manner, and the workbench 1 is provided with a cutting groove 405 used in cooperation with the cutting knife 401.

[0028] The frame 2 is fixedly connected with an air cylinder 404, and the fixed box 4 is fixedly connected with the output end of the air cylinder 404.

[0029] When the frame 2 descends and the pressing plates 206 press the sound-absorbing sponge, the air cylinder 404 is started, the output end of the air cylinder 404 extends, drives the fixed box 4 to descend, as the fixed box 4 continuously descends, the cutting knife 401 which descends synchronously with the fixed box 4 is inserted into the sound-absorbing sponge, and the cutting knife 401 can smoothly cut the sound-absorbing sponge by means of the cutting groove 405 on the workbench 1, after cutting, the output end of the air cylinder 404 is retracted, drives the fixed box 4 and the cutting knife 401 to ascend and reset, so as to perform the next cutting operation;
