DETAILED DESCRIPTION

[0027] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For example, see Figures 1 to 11The present invention provides a technical solution: it includes a stamping equipment body 1, the outer wall at the top of the stamping equipment body 1 is fixedly connected to an equipment box 2, the upper part of the equipment box 2 is fixedly connected to a cylinder 3, the output end of the cylinder 3 is slidably connected to a push rod 32, the bottom of the push rod 32 is rotatably connected to a mounting shell 5, the inside of the mounting shell 5 is movably connected to a mounting plate 51, the outer wall at the bottom of the mounting plate 51 is fixedly connected to a grinding plate 52, the outer wall at the top of the mounting plate 51 is fixedly connected to a stamping block 53, the inside of the mounting shell 5 is slidably connected to an L-shaped slide plate 54, the top of the L-shaped slide plate 54 is fixedly connected to a pulling spring 55, the outer wall at the bottom of the pulling spring 55 is fixedly connected to the outer wall at the top of the mounting shell 5, and the opposite sides of the two L-shaped slide plates 54 are rotatably connected to the outer wall of the mounting plate 51.

[0029] By pushing the mounting shell 5 to move through the fixing ring 33, the stamping block 53 can stamp the metal plate, so that the metal plate is stamped into a speaker dust screen. The stamping process is a precise metal forming process, which can ensure that the speaker dust screen has an accurate shape and size, thereby ensuring that the dust screen can perfectly fit the speaker, which not only has a dustproof effect, but also does not affect the sound quality transmission. At the same time, less waste is generated during the stamping process, which is easy to recycle and reuse, meeting the requirements of environmental protection and sustainable development. The mounting shell 5 is driven to rotate by the fixing ring 33, so that the grinding plate 52 grinds the speaker dust screen, thereby avoiding burrs on the speaker dust screen during the stamping process. Correspondingly, through the setting of the grinding plate 52, the burrs, unevenness and other surface defects generated in the stamping process can be removed, making the surface of the speaker dust screen smoother and flatter, which can not only improve the appearance quality of the product, but also reduce the sound quality problems that may be caused by the uneven surface. Grinding the speaker dust screen after stamping is an effective means to improve product quality, improve sound quality, enhance durability and facilitate cleaning and maintenance.

[0030] Embodiment 2, on the basis of embodiment 1, a motor 4 is fixedly connected to the lower part of the interior of the equipment box 2, a driving wheel 41 is fixedly connected to the outer wall of the output end of the motor 4, a driven wheel 43 is rotatably connected to the outer wall of the cylinder 3, the outer wall of the driving wheel 41 is meshingly connected to the outer wall of the driven wheel 43, a blade 42 is fixedly connected to the outer wall of the top of the driving wheel 41, a mounting groove 31 is fixedly connected to the outer wall of the bottom of the driven wheel 43, a slide rod 34 is slidably connected to the interior of the mounting groove 31, a fixing ring 33 is fixedly connected to the outer wall of the bottom of the slide rod 34, the outer wall of the bottom of the fixing ring 33 is fixedly connected to the outer wall of the top of the mounting shell 5, a reset spring 36 is fixedly connected to the upper part of the interior of the mounting groove 31, the outer wall of the bottom of the reset spring 36 is fixedly connected to the outer wall of the top of the slide rod 34, and the outer wall of the push rod 32 is rotatably connected to the inner wall of the fixing ring 33.

[0031] By having the slide bar 34 move along with the push rod 32, the movement trajectory of the push rod 32 can be limited, and the support structure for the push rod 32 can be increased accordingly, thereby reducing the shaking and vibration of the push rod 32 during movement, and helping to maintain the stability and accuracy of the push rod 32. Especially in applications requiring high-precision control, the movement of the slide bar 34 is synchronized with that of the push rod 32, thereby ensuring that the push rod 32 moves along a predetermined trajectory.

[0032] Embodiment 3, on the basis of embodiment 2, a cavity is provided at the lower part of the interior of the push rod 32, a groove is provided at a position near the upper part of the cavity of the push rod 32, a rotating rod 6 is rotatably connected to the upper part of the interior of the cavity of the push rod 32, a gear 2 65 is fixedly connected to the outer wall of the rotating rod 6, a sliding shell 61 is slidably connected to the outer wall of the rotating rod 6, a support plate is fixedly connected to the outer wall of the sliding shell 61, an electric telescopic rod 62 is fixedly connected to the outer wall of the top of the support plate, an output end of the electric telescopic rod 62 is rotatably connected to a gear 3 66, and the outer wall of the gear 3 66 is meshed with the outer wall of the gear 2 65 Then, the outer wall of gear three 66 is meshedly connected with gear one 64, the outer wall of one side of gear one 64 is fixedly connected with the mounting ring 35, the outer wall of the bottom of the mounting ring 35 is fixedly connected with the outer wall of the top of the fixing ring 33, the outer wall of the rotating rod 6 is provided with a track 67, the outer wall of the track 67 is slidably connected with the limiting block 68, the outer wall of the track 67 is fixedly connected with the inside of the sliding shell 61, the bottom of the sliding shell 61 is fixedly connected with a push block 63, the outer wall of the bottom of the push block 63 is in active contact with the outer wall of the top of the stamping block 53, and the outer wall of the sliding shell 61 is slidably connected with the inside of the cavity on the push rod 32.

[0033] By moving the limit block 68 along the track 67, the limit block 68 can drive the sliding shell 61 to move downward, so that the push block 63 pushes the mounting plate 51 to move downward inside the mounting shell 5. Then, when the mounting plate 51 moves downward, the sliding rod 34 can move downward on the mounting shell 5, so that the mounting plate 51 is moved out from the inside of the mounting shell 5, so that the mounting shell 5 can be turned over, avoiding the inconvenience of turning over the mounting plate 51 inside the mounting shell 5, and correspondingly increasing the flexibility of the mounting plate 51.

[0034] Embodiment 4, on the basis of embodiment 3, a storage box 71 is provided inside the rotating rod 6, and a sealing push plate 72 is slidably connected inside the storage box 71, and a sealing gasket is fixedly connected to the outer wall of the sealing push plate 72, and a push rod 7 is fixedly connected to the outer wall of the bottom of the sealing push plate 72, and the outer wall of the push rod 7 passes through the bottom of the storage box 71 and is fixedly connected to the lower part of the sliding shell 61, an oil outlet hole 73 is provided at the bottom of one side of the rotating rod 6, and the outer walls of the tops of multiple oil outlet holes 73 are connected through the interior of the storage box 71, a drainage groove 75 is provided at the top of the gear 2 65 below the oil outlet hole 73, and a diversion groove 76 is provided at the top of the gear 2 65 at the top of the tooth, the outer walls of one side of the multiple diversion grooves 76 are connected through the outer wall of one side of the drainage groove 75, and the outer wall of the gear 2 65 is fixedly connected to a perforated plate 74.

[0035] By setting the oil outlet hole 73, the lubricating oil enters the drainage groove 75 on the gear 2 65 through the oil outlet hole 73, and then flows into the diverter groove 76 through the drainage groove 75, and finally enters the perforated plate 74 through the diverter groove 76, so as to lubricate the outer wall of the gear 2 65, thereby avoiding large friction between the gear 2 65 and the gear 3 66. Accordingly, the presence of the lubricating oil can reduce the direct contact between the tooth surfaces, thereby reducing the risk of wear and scratches, helping to maintain the accuracy and performance of the gears, and also extending the service life of the gears. To further improve the running stability and comfort of gear two 65, and make the installation shell 5 move up and down more smoothly and quickly, the lubricating oil entering the gear two 65 can be temporarily stored and transferred through the holes set on the perforated plate 74. When the gear two 65 contacts the gear three 66, the lubricating oil can be transferred to the gear three 66, and then transferred to the gear one 64 through the gear three 66, so that the efficiency of the installation shell 5 during the movement process can be improved, so that it can complete the up and down movement more smoothly and quickly, thereby improving the movement efficiency of the installation shell 5.

[0036] The working principle and use process of the present invention are as follows: during operation, first, the metal plate to be pressed into a speaker dustproof net is placed in the placement groove on the stamping equipment body 1 for fixing, and then the cylinder 3 can be started to move, and then through the movement of the cylinder 3, the push rod 32 can drive the fixing ring 33 to move downward, so that the fixing ring 33 pushes the mounting shell 5 to move, and the stamping block 53 can stamp the metal plate, so that the metal plate is stamped into a speaker dustproof net. The stamping process is a precise metal forming process, which can ensure that the speaker dustproof net has an accurate shape and size, thereby ensuring that the dustproof net can perfectly fit the speaker, which not only has a dustproof effect, but also does not affect the sound quality transmission. At the same time, less waste is generated during the stamping process, which is easy to recycle and reuse, and meets the requirements of environmental protection and sustainable development.

[0037] By driving the fixed ring 33 to move downward through the push rod 32, the slide rod 34 can be driven to slide inside the reset spring 36. Then, the slide rod 34 moves along with the push rod 32 to limit the movement trajectory of the push rod 32. Accordingly, the support structure for the push rod 32 is increased, and the shaking and vibration of the push rod 32 during the movement are reduced, which helps to maintain the stability and accuracy of the push rod 32. Especially in applications that require high-precision control, the movement of the slide rod 34 is synchronized with the movement of the push rod 32, thereby ensuring that the push rod 32 moves according to the predetermined trajectory.

[0038] After the speaker dust screen is pressed, the cylinder 3 can drive the push rod 32 to move upward, remove the inside of the placement slot, and start the motor 4. Then, through the movement of the motor 4, the driving wheel 41 can drive the driven wheel 43 to rotate on the cylinder 3. Then, through the rotation of the driven wheel 43, the sliding rod 34 can drive the fixing ring 33 to rotate. Then, through the movement of the fixing ring 33, the mounting ring 35 can drive the gear 1 64 to rotate. Then, through the rotation of the gear 1 64, the gear 3 66 can drive the gear 2 65 to rotate. The rotating rod 6 drives the track 67 to rotate, and then the limit block 68 moves along the track 67, so that the limit block 68 can drive the sliding shell 61 to move downward, so that the push block 63 pushes the mounting plate 51 to move downward inside the mounting shell 5, and then when the mounting plate 51 moves downward, the sliding rod 34 can move downward on the mounting shell 5, so that the mounting plate 51 is moved out from the inside of the mounting shell 5, so as to flip the mounting shell 5, thereby avoiding the inconvenience of flipping the mounting plate 51 inside the mounting shell 5, and correspondingly increasing the flexibility of the mounting plate 51.

[0039] When the sliding shell 61 is driven to move upward or downward by the limit block 68, the sliding shell 61 can drive the push rod 7 to move accordingly through the fixed connection between the sliding shell 61 and the push rod 7. When the push rod 7 moves upward inside the storage box 71, the push rod 7 can push the sealing push plate 72 to push the lubricating oil inside the storage box 71 upward, so that the lubricating oil below the push rod 7 moves upward. When the lubricating oil moves to the top of the storage box 71, it can pass through the oil outlet hole 73 to allow the lubricating oil to enter the drainage groove 75 on the gear 2 65 through the oil outlet hole 73, and then flow into the inside of the diverter groove 76 through the drainage groove 75, and finally enter the perforated plate 74 through the diverter groove 76, so as to lubricate the outer wall of the gear 2 65, thereby avoiding the gear 2 65 The friction between gear three 66 is relatively large, and the presence of lubricating oil can reduce the direct contact between the tooth surfaces, thereby reducing the risk of wear and scratches, helping to maintain the accuracy and performance of the gears, and extending the service life of the gears, further improving the running stability and comfort of gear two 65, and making the mounting shell 5 smoother and faster in the process of up and down movement. The lubricating oil entering the gear two 65 can be temporarily stored and transferred through the holes set on the perforated plate 74. When gear two 65 contacts gear three 66, the lubricating oil can be transferred to gear three 66, and then transferred to gear one 64 through gear three 66, so that the efficiency of the mounting shell 5 in the movement process can be improved, so that it can complete the up and down movement more smoothly and quickly, thereby improving the movement efficiency of the mounting shell 5.

[0040] Then, through the blades 42 installed on the driving wheel 41, when the driving wheel 41 rotates, the blades 42 can rotate accordingly, and then through the rotation of the blades 42, wind can be generated, so as to blow the air in the equipment box 2, increase the fluidity of the air inside the equipment box 2, and blow out the hot air inside the equipment box 2 to reduce the temperature inside the equipment box 2. By reducing the temperature inside the equipment box 2, the heat dissipation of the cylinder 3 can be accelerated, and when the cylinder 3 is overheated, its internal parts may have slight thermal expansion, thereby affecting the stamping accuracy. Accordingly, cooling the cylinder 3 can reduce this thermal expansion phenomenon, ensure the precise fit between the mold and the material during the stamping process, thereby improving the size accuracy and shape accuracy of the product.

[0041] By starting the electric telescopic rod 62 to move, the movement of the electric telescopic rod 62 can drive the gear three 66 to move downward, so that the gear three 66 leaves the tooth grooves of the gear one 64 and the gear two 65, and the connection between the gear two 65 and the gear one 64 can be released. At this time, when the mounting ring 35 drives the gear one 64 to rotate, the gear two 65 cannot drive the rotating rod 6 to move, so that the rotating rod 6 drives the sliding shell 61 to remain stationary, which correspondingly increases the flexibility of the rotating rod 6.

[0042] After the mounting plate 51 is removed from the mounting shell 5, the operator can rotate the mounting plate 51 to flip the mounting plate 51 on the L-shaped slide plate 54, so that the stamping block 53 moves to the top of the mounting plate 51 and the polishing plate 52 moves to the bottom of the mounting plate 51, so as to polish the speaker dust screen. By closely connecting the stamping and polishing steps, the waiting time and material handling time in the intermediate links can be reduced, thereby improving the overall production efficiency.

[0043] After the polishing plate 52 is turned over, the spring 55 can be pulled to push the L-shaped slide plate 54 to move upward, and then the movement of the L-shaped slide plate 54 can drive the mounting plate 51 to enter the interior of the mounting shell 5. At this time, the movement of the cylinder 3 can make the push rod 32 push the mounting shell 5 to enter the interior of the placement groove again, so as to polish the speaker dust screen.

[0044] At this time, through the movement of the motor 4, the driven wheel 43 can drive the slide rod 34 to rotate, and then through the movement of the slide rod 34, the fixed ring 33 can drive the mounting shell 5 to rotate, so that the polishing plate 52 can polish the speaker dustproof net, avoiding the occurrence of burrs on the speaker dustproof net during the stamping process. Correspondingly, through the setting of the polishing plate 52, the burrs, unevenness and other surface defects generated in the stamping process can be removed, making the surface of the speaker dustproof net smoother and flatter, which can not only improve the appearance quality of the product, but also reduce the sound quality problems that may be caused by the uneven surface. Polishing the speaker dustproof net after stamping is an effective means to improve product quality, improve sound quality, enhance durability and facilitate cleaning and maintenance.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
