Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker plastic technology, specifically relating to a stamping device for the production and processing of loudspeaker plastic edge pressing. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. The performance of a loudspeaker has a great impact on sound quality. The loudspeaker is the weakest component in an audio system, yet it is also the most important component for sound effects. There are many types of loudspeakers, and their prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric, or electrostatic effects, causing it to resonate with the surrounding air and produce sound. The production of loudspeaker plastic requires the use of stamping equipment.

[0003] Existing stamping equipment lacks a mechanism for positioning the workpiece during operation, causing the workpiece to easily deviate from its intended position during the stamping process. This leads to changes in the stamping position of the workpiece and reduces the stamping accuracy. Therefore, we provide a stamping device for the production and processing of speaker plastic edge pressing. Utility Model Content

[0004] The purpose of this invention is to provide a stamping device for the production and processing of plastic edge pressing for loudspeakers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for producing plastic edge pressing for loudspeakers, comprising a base box and a snap-fit ​​post. The top of the base box is fixedly connected to an edge pressing mold, and the bottom of the edge pressing mold has a first through hole. A vacuum pump is fixedly installed on the left side of the inner cavity of the base box. The output end of the vacuum pump is connected to a second pipe, one end of the second pipe is connected to an air outlet hood, the input end of the vacuum pump is connected to a first pipe, one end of the first pipe is connected to a suction cup, and a second through hole is opened on the top of the base box at the same position as the first through hole at the bottom of the edge pressing mold.

[0006] Using the above scheme, a vacuum pump, in conjunction with pipe number one, extracts the air from the suction cup and outputs the gas through pipe number two and the air hood, creating a vacuum inside the suction cup and reducing the internal pressure. Since the external atmospheric pressure is higher than the pressure inside the suction cup, a pressure difference is generated, causing the plastic to be adsorbed to the bottom of the inner side of the pressing mold, preventing the plastic from shifting to the predetermined position during the stamping process, and greatly improving the stamping accuracy. Similarly, when the vacuum disappears, the adsorption force disappears, making it easier to remove the material later.

[0007] In a preferred embodiment of a stamping device for producing plastic edge pressing for loudspeakers, an L-shaped frame is fixedly connected to the left side of the top of the edge pressing mold, a hydraulic cylinder is fixedly connected to the top of the L-shaped frame, a snap-fit ​​block is fixedly connected to the bottom of the hydraulic cylinder, the snap-fit ​​post and the snap-fit ​​block are fixedly connected by bolts, a reinforcing rib is fixedly connected to the surface of the snap-fit ​​post, and an edge pressing plate is fixedly connected to the bottom of the reinforcing rib.

[0008] Using the above scheme, the hydraulic cylinder drives the snap-fit ​​block to move downward, the snap-fit ​​block drives the snap-fit ​​column to move downward, the snap-fit ​​column drives the reinforcing rib to move downward, and the reinforcing rib drives the pressing plate to move downward. When the bottom of the pressing plate contacts the plastic, because the inside of the pressing plate is hollow, the pressing plate can be used to press the edge of the plastic.

[0009] In a preferred embodiment of a stamping device for producing plastic edge pressing for loudspeakers, a power supply box is fixedly connected to the left side of the top of the L-shaped frame, and a storage battery is provided inside the power supply box.

[0010] By adopting the above solution, the electrical equipment is powered by a storage battery to maintain its normal operation.

[0011] In a preferred embodiment of a stamping device for producing plastic edge pressing for loudspeakers, a PLC controller is fixedly connected to the left side of the L-shaped frame, and the PLC controller is electrically connected to the electrical equipment via a connecting cable.

[0012] By adopting the above solution, the PLC controller can be set to start and stop the electrical equipment in real time, making it convenient for users to operate.

[0013] In a preferred embodiment of a stamping device for producing plastic edge pressing for loudspeakers, four anti-slip pads are adhered to all four sides of the bottom of the base box.

[0014] By adopting the above solution and setting anti-slip pads, the friction between the base box and the contact surface is increased, and the device has an anti-slip function, which greatly improves the stability of the device during operation.

[0015] In a preferred embodiment of a stamping device for producing plastic edge pressing for loudspeakers, both sides of the bottom of the vacuum pump are fixedly connected to limit frames, and the bottom of the limit frames is fixedly connected to the bottom of the inner cavity of the base box.

[0016] By adopting the above solution and setting up a limit frame, the amplitude of vibration during vacuum pump operation is reduced, thereby achieving the purpose of vibration reduction and noise reduction.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a vacuum pump to extract air from the suction cup with the help of pipe number one, and outputs the gas through pipe number two and the air hood, so that a vacuum state is formed inside the suction cup, reducing the pressure inside the suction cup. Since the external atmospheric pressure is higher than the pressure inside the suction cup, a pressure difference is generated, which causes the plastic to be adsorbed on the bottom of the inner side of the pressing mold, preventing the plastic from deviating from the predetermined position during the stamping process, and greatly improving the stamping accuracy. Similarly, when the vacuum state disappears, the adsorption force disappears, which facilitates the subsequent material removal.

[0019] 2. This utility model uses a hydraulic cylinder to drive the snap-fit ​​block to move downward, which in turn drives the snap-fit ​​column to move downward, which in turn drives the reinforcing rib to move downward, and the reinforcing rib to move the pressing plate downward. When the bottom of the pressing plate contacts the plastic, the pressing plate is hollow inside, so the edge of the plastic can be pressed. Attached Figure Description

[0024] Please see Figure 1-3 A stamping device for producing plastic edge pressing for loudspeakers, comprising a base box 1 and a snap-fit ​​post 13, see Figure 1 As shown, four anti-slip pads are adhered to all four sides of the bottom of the base box 1. These anti-slip pads increase the friction between the base box 1 and the contact surface, providing an anti-slip function and significantly improving the stability of the device during operation. A pressing mold 2 is fixedly connected to the top of the base box 1. Figure 2As shown, an L-shaped frame 10 is fixedly connected to the top left side of the pressing mold 2. A hydraulic cylinder 11 is fixedly connected to the top of the L-shaped frame 10. A locking block 12 is fixedly connected to the bottom of the hydraulic cylinder 11. The locking post 13 and the locking block 12 are fixedly connected by bolts 16. A reinforcing rib 14 is fixedly connected to the surface of the locking post 13. A pressing plate 15 is fixedly connected to the bottom of the reinforcing rib 14. The hydraulic cylinder 11 drives the locking block 12 to move downward, which in turn drives the locking post 13 to move downward. The locking post 13 then drives the reinforcing rib 14 to move downward, which in turn drives the pressing plate 15 to move downward. When the bottom of the pressing plate 15 contacts the plastic, the pressing plate 15 can be used to press the edge of the plastic because its interior is hollow. The pressing mold 2 has a first through hole 3 at the bottom. The left side of the inner cavity of the base box 1 is fixed... A vacuum pump 4 is installed, with its output end connected to a second pipe 8. One end of the second pipe 8 is connected to an air outlet hood 9, and the input end of the vacuum pump 4 is connected to a first pipe 5. One end of the first pipe 5 is connected to a suction cup 6. A second through hole 7 is provided on the top of the base box 1, at the same position as the first through hole 3 at the bottom of the pressing mold 2. With the cooperation of the vacuum pump 4 and the first pipe 5, the air inside the suction cup 6 is extracted, and the gas is output through the second pipe 8 and the air outlet hood 9, so that a vacuum state is formed inside the suction cup 6, reducing the pressure inside the suction cup 6. Since the external atmospheric pressure is higher than the pressure inside the suction cup 6, a pressure difference is generated, which causes the plastic to be adsorbed on the bottom of the inner side of the pressing mold 2, preventing the plastic from deviating from the predetermined position during the stamping process, greatly improving the stamping accuracy. Similarly, when the vacuum state disappears, the adsorption force disappears, making it easier to remove the material later.

[0025] See Figure 2 As shown, a power supply box is fixedly connected to the top left side of the L-shaped frame 10, and the inner cavity of the power supply box is equipped with a storage battery. The storage battery provides power to the electrical equipment, maintaining its normal operation. Figure 1 As shown, a PLC controller 17 is fixedly connected to the left side of the L-shaped frame 10. The PLC controller 17 is electrically connected to the electrical equipment via a connecting cable. The PLC controller 17 allows for real-time start-up and shutdown of the electrical equipment, facilitating user operation. Figure 3 As shown, limit frames are fixedly connected to both sides of the bottom of the vacuum pump 4, and the bottom of the limit frames is fixedly connected to the bottom of the inner cavity of the base box 1. By setting the limit frames, the amplitude of vibration of the vacuum pump 4 during operation is reduced, thereby achieving the purpose of vibration reduction and noise reduction.

[0026] In use, first, place the plastic to be pressed inside the pressing mold 2, at the top of the first through hole 3. Then, start the vacuum pump 4. With the assistance of pipe 5, the vacuum pump 4 extracts air from the suction cup 6 and outputs the gas through pipe 8 and the exhaust hood 9, creating a vacuum inside the suction cup 6 and reducing the internal pressure. Since the external atmospheric pressure is higher than the internal pressure of the suction cup 6, a pressure difference is created, causing the plastic to be adsorbed onto the bottom of the inner side of the pressing mold 2. Similarly, when the vacuum disappears, the adsorption force disappears, facilitating subsequent material removal. Then, start the hydraulic cylinder 11, using hydraulic pressure... The cylinder 11 drives the snap-fit ​​block 12 to move downwards, which in turn drives the snap-fit ​​post 13 to move downwards. The snap-fit ​​post 13 then drives the reinforcing rib 14 to move downwards, which in turn drives the pressing plate 15 to move downwards. When the bottom of the pressing plate 15 contacts the plastic, the pressing plate 15 is hollow inside, allowing for pressing operations on the edge of the plastic. Since the pressing plate 15 and the snap-fit ​​block 12 are fixedly connected by bolts 16, it can be seen that the pressing plate 15 can be replaced simply by releasing the bolts 16 from its position, thus making it suitable for pressing plastics of different sizes.
