[0027] Example

[0028] Please see Figures 1-5 This utility model provides a technical solution: a box body stamping and riveting equipment, including a base 1, a mounting frame 2 installed on the top of the base 1; a stamping assembly, which is installed on the mounting frame 2, and a lower module is installed on the top of the base 1; and a fixing assembly, which is installed on the top of the base 1 and is used to fix the lower module.

[0029] By setting up a fixing component, the placement base 7 can be quickly disassembled without the need for tools, effectively improving the efficiency of lower module maintenance. The fixing component includes two fixing brackets 15, a limiting plate 18, and an elliptical disk 20. The two fixing brackets 15 are fixedly connected to the top sides of the base 1. The two fixing brackets 15 are respectively provided with a first through groove 16 and a second through groove 17. The limiting plate 18 is movably inserted through the interior of the second through groove 17. The elliptical disk 20 is mounted inside the first through groove 16 via a shaft. A limiting groove 19 is provided on one side of the limiting plate 18. The elliptical disc 20 matches the limiting groove 19. The elliptical disc 20 is snapped into the inside of the limiting groove 19. A tension spring 22 is movably sleeved on the outside of the guide rod 21. The tension spring 22 is located between the limiting plate 18 and the fixing frame 15. By pulling the handle of the elliptical disc 20 forward, the handle drives the elliptical disc 20 to rotate, causing the elliptical disc 20 to disengage from the inside of the limiting groove 19. At this time, the limiting plate 18 moves inside the second through groove 17 under the force of the tension spring 22, causing the limiting plate 18 to disengage from the inside of the mounting groove 14. Then the placement seat 7 can be disassembled.

[0030] Guide rods 21 are fixedly connected to both ends of one side of the limiting plate 18. One end of the guide rod 21 passes through one side of the fixing frame 15. During installation, by placing the placement seat 7 inside the two fixing frames 15, and by pushing the handle of the elliptical disc 20 backward, one end of the elliptical disc 20 moves into the interior of the limiting groove 19. During this process, the elliptical disc 20 pushes one side of the limiting plate 18 to move into the interior of the mounting groove 14 by squeezing, thus completing the installation of the placement seat 7.

[0031] The stamping assembly includes a mounting bracket 2, a hydraulic cylinder 3, and a fixed seat 4. The mounting bracket 2 is mounted on the top of the base 1, the hydraulic cylinder 3 is mounted on the top of the mounting bracket 2, and the fixed seat 4 is mounted on the piston rod of the hydraulic cylinder 3. A mounting seat 5 is mounted on the bottom of the fixed seat 4, and a stamping head 6 is mounted on the bottom of the mounting seat 5. When the box body is stamped and riveted, the box body is fitted onto the outside of the support seat 9, so that its bottom is placed above the push plate 12. The lower module includes a placement seat 7 and a support seat 9. The placement seat 7 is mounted on the top of the base 1 and located between the two fixed brackets 15. A groove 8 is opened at the front end of the placement seat 7, and the support seat 9 is located behind the groove 8. A stamping hole 10 is opened at the top of the support seat 9. Both ends of 7 are provided with mounting grooves 14, and the limiting plate 18 matches the mounting groove 14. The limiting plate 18 is inserted into the inside of the mounting groove 14. The bottom of the inner side of the groove 8 is provided with an ejector assembly. The piston rod of the hydraulic cylinder 3 drives the punch head 6 at the bottom of the mounting base 5 to move downward through the fixed base 4, so that the punch head 6 abuts against the top of the box and pushes the box to move downward, so that the inner side of the box abuts against the top of the support base 9. With the cooperation of the punch head 6 and the punch hole 10, the punching and riveting of the box body can be completed quickly. The processing of the ventilation fan box is completed by punching and riveting. Compared with the traditional welded box, it is more beautiful and reliable, thus meeting people's demand for high-quality home furnishings.

[0032] To facilitate the removal of the processed box, the ejection assembly includes two guide posts 11, a push plate 12, and a telescopic spring 13. The two guide posts 11 are fixedly connected to the bottom inner side of the groove 8. The push plate 12 is movably sleeved on the outside of the two guide posts 11. The telescopic spring 13 is movably sleeved on the outside of the guide posts 11 and is located between the push plate 12 and the bottom of the groove 8. During the stamping and riveting process, the bottom of the box pushes the push plate 12 to move outside the guide posts 11. At this time, the telescopic spring 13 is compressed by force. After the stamping is completed, the stamping head 6 disengages from the top of the box. At this time, the telescopic spring 13 drives the box to move upward, so that the stamped part of the box disengages from the inside of the stamping hole 10.

[0033] Working principle or structural principle: When the box body is stamped and riveted, the box body is fitted onto the outside of the support base 9, with its bottom placed above the push plate 12. Then, the hydraulic station is started by controlling the switch group. The piston rod of the hydraulic cylinder 3 drives the stamping head 6 at the bottom of the mounting base 5 to move downward through the fixed base 4, so that the stamping head 6 abuts against the top of the box body and pushes the box body downward, so that the inner side of the box body abuts against the top of the support base 9. With the stamping head 6 cooperating with the stamping hole 10, the stamping and riveting of the box body can be completed quickly. During the stamping and riveting process, the bottom of the box body pushes the push plate 12 to move outside the guide post 11. At this time, the telescopic spring 13 is compressed by force. After the stamping is completed, the stamping head 6 is removed from the top of the box body. At this time, the telescopic spring 13 drives the box body to move upward, so that the stamped part of the box body is removed from the inside of the stamping hole 10, thus making it easy to take out the processed box body, saving time and effort.

[0034] When maintenance of the lower module is required, pull the handle of the elliptical disc 20 forward. The handle will rotate the elliptical disc 20, causing it to disengage from the limiting groove 19. At this time, the limiting plate 18 will move inside the second through groove 17 under the force of the tension spring 22, causing the limiting plate 18 to disengage from the mounting groove 14. Then the placement seat 7 can be disassembled. The operation is simple and quick. During installation, place the placement seat 7 inside the two fixing brackets 15, and push the handle of the elliptical disc 20 backward to move one end of the elliptical disc 20 into the limiting groove 19. During this process, the elliptical disc 20 will push one side of the limiting plate 18 into the mounting groove 14 by squeezing, thus completing the installation of the placement seat 7.
