DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1 - Figure 6A stamping device for multi-station automobile parts processing includes a base 1, a plurality of support columns 2 are fixedly connected to the top of the base 1, a top plate 3 is fixedly connected to the top of the plurality of support columns 2, two cylinders 4 are fixedly connected to the top of the top plate 3, and the output ends of the two cylinders 4 are commonly fixedly connected to a limiting plate 5, the limiting plate 5 is provided with a plurality of sliding openings, the sliding openings are slidably connected to the outer side walls of the support columns 2, the outer side walls of the plurality of support columns 2 are all sleeved with return springs 17, the top of the return spring 17 is fixedly connected to the bottom of the limit plate 5, the bottom of the return spring 17 is fixedly connected to the top of the base 1, a pressing mechanism is provided at the bottom of the limit plate 5, the pressing mechanism is connected to an upper pressure column 8 and a plurality of punching heads 7, the upper pressure column 8 is located at the center point of the mounting plate 6, and the plurality of punching heads 7 are evenly surrounded by the upper pressure column 8, a fixing plate 18 is fixedly connected to the top of the base 1, and a pneumatic mechanism is provided on the fixing plate 18.

[0027] The base 1 is used to support the structure of the entire punching device to ensure its stability and reliability. The support column 2 serves to firmly connect the top plate 3 and the base 1, making the entire device more stable. The two cylinders 4 are fixed on the top of the top plate 3, and drive the limit plate 5 to move up and down through their output ends to achieve the functions of pressing and rebounding. The sliding opening on the limit plate 5 cooperates with the sliding of the support column 2 to ensure the precise movement of the limit plate 5 in the vertical direction. The reset spring 17 provides an elastic restoring force between the bottom of the limit plate 5 and the base 1 to help the limit plate 5 quickly return to the starting position.

[0028] The pressing mechanism includes a mounting plate 6, a accommodating cavity 10 is provided on the limiting plate 5, the mounting plate 6 is installed in the accommodating cavity 10, and can rotate along the accommodating cavity 10, two supporting grooves 27 are provided on both sides of the accommodating cavity 10, and the two supporting grooves 27 are respectively provided at the two ends of the accommodating cavity 10, and two protrusions 9 are provided on the top of the mounting plate 6, and the protrusions 9 are provided on the edge of the mounting plate 6, and the positions of the protrusions 9 and the supporting grooves 27 correspond one by one, and two elastic pins are provided on the mounting plate 6.

[0029] The limiting plate 5 is provided with an inserting hole 12 matched with the elastic pin, and the elastic pin can be inserted into the inserting hole 12 as the mounting plate 6 rotates.

[0030] These elastic pins can cooperate with the insertion holes 12 on the limiting plate 5 when the mounting plate 6 rotates to achieve a positioning function.

[0031] The elastic pin includes a rigid head 15 and a telescopic spring 16. A placement hole 13 is provided on the protrusion 9. A telescopic rod 14 is fixedly connected to the top of the placement hole 13. The top of the telescopic rod 14 is fixedly connected to the bottom of the rigid head 15. The telescopic spring 16 is sleeved on the outside of the telescopic rod 14. The two ends of the telescopic spring 16 are respectively fixedly connected to the bottom of the rigid head 15 and the bottom of the placement hole 13.

[0032] With this structural design, the elastic pin can be flexibly extended and retracted to ensure that it can be reliably inserted into or withdrawn from the insertion hole 12 of the limiting plate 5 when needed.

[0033] The pneumatic mechanism includes a cavity 23 and multiple installation cavities 19. The cavity 23 is located inside the center of the fixed plate 18. The multiple installation cavities 19 correspond one-to-one to the multiple punching heads 7. The inner walls of the multiple installation cavities 19 are connected to airbags 20. The multiple airbags 20 are connected to the cavity 23 through ventilation pipes 26. The inner wall of the cavity 23 is slidably connected to a partition 24. The top of the partition 24 is fixedly connected to an extrusion column 21. The extrusion column 21 passes through the top of the fixed plate 18 and is fixedly connected to a pressing plate 22. An air spring 25 is fixedly connected between the partition 24 and the top of the cavity 23.

[0034] When the pressing plate 22 is subjected to external pressure, the partition 24 is pushed to slide in the cavity 23 through the extrusion column 21, thereby compressing the air spring 25. The air is transmitted to each airbag 20 through the ventilation duct 26 to fix the stamping part. The upper pressure column 8 corresponds to the position of the pressing plate 22.

[0035] The specific working principle of the present invention is as follows:

[0036] During actual operation, when this device is used, the two cylinders 4 located on the top of the top plate 3 are started first. The output ends of the cylinders 4 drive the limit plate 5 to descend by being connected together. The sliding opening on the limit plate 5 slides along the support column 2 to ensure the stability of the entire device during the up and down movement. At the same time, the reset springs 17 on the outer walls of the multiple support columns 2 are gradually compressed during the descent of the limit plate 5, preparing for the subsequent automatic reset.

[0037] Next, the pressing mechanism at the bottom of the limit plate 5 starts to work, the upper pressing column 8 corresponds to the position of the pressing plate 22, and the upper pressing column 8 squeezes the pressing plate 22. When the pressing plate 22 is pressed down by the upper pressing column 8, the pressing plate 22 pushes the partition 24 into the cavity 23 through the squeezing column 21, and the air in the cavity 23 is squeezed and enters each airbag 20 through the ventilation pipe 26, so that the airbag 20 expands. The expanded airbag 20 wraps the automobile parts to be processed, so that the automobile parts are fixed, and then multiple punching heads 7 punch the automobile parts to complete the punching process.

[0038] When the upper pressure column 8 rebounds, the partition plate 24 is pushed back to its original position by the air spring 25 at the top of the cavity 23, and the air in the airbag 20 flows back to the cavity 23, completing a stamping cycle.

[0039] In addition, when the punch head 7 is damaged and needs to be replaced, the elastic pin on the mounting plate 6 cooperates with the socket 12 on the limit plate 5, and the elastic pin is inserted into or disengaged from the socket 12 by rotating the mounting plate 6, thereby fixing and unlocking the mounting plate 6.

[0040] Press the elastic pin to disengage it from the socket 12, and rotate the mounting plate 6 to press the elasticity to rotate in the accommodating cavity 10. When the elastic pin and the protrusion 9 are simultaneously turned to the support groove 27 position, the mounting plate 6 can be taken out. When it needs to be installed, it is only necessary to press the elastic pin and rotate the mounting plate 6 at the same time to make the elastic pin enter the accommodating cavity 10. Rotate the mounting plate 6 to insert the elastic pin into the socket 12, and the replacement of the punch head 7 is completed.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
