Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a stripping device for stamping thin sheet metal parts. Background Technology

[0002] In the stamping process of thin sheet metal parts, the unloading device is an indispensable and important component. Its main function is to remove the stamped thin sheet metal parts from the mold and unload them smoothly so that they can be processed or handled in subsequent processes.

[0003] A search revealed a patent, CN222020544U, which discloses a rapid stripping stamping device. This device includes an outer frame, a stamping die, and auxiliary stripping components. A worktable is fixed to the center of the outer frame, and a base plate is mounted on the upper side of the worktable. Side frames are fixed to the left and right sides above the base plate, and a stamping die is fixed between the side frames. The stamping die includes a die housing, a supporting electromagnet, a magnetic suction plate, a bottom template, and a telescopic spring. Supporting electromagnets are fixed to the front and rear sides of the lower interior of the die housing, and a magnetic suction plate is provided above the supporting electromagnets. This rapid stripping stamping device uses a motor and shaft to easily drive the rotation of an eccentric wheel, allowing the eccentric wheel to reciprocate and push the upper L-shaped block. This causes the magnetic suction plate and bottom template to vibrate, increasing the vibration amplitude of the telescopic spring and further improving the stripping efficiency of the stamped parts, thus avoiding the situation where the stamped parts stick to the stamping die and are difficult to eject.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document uses a spring-loaded, movable bottom template to achieve the stripping effect after stamping metal parts. However, in actual operation, when stamping thin sheet metal parts, a large force is required during stamping. Since the bottom template in the aforementioned comparative document is movable, its position may shift during the stamping process, leading to deviations in the stamping dimensions and reducing the dimensional accuracy of the stamped thin sheet metal parts. Therefore, there is an urgent need in the art to improve the stripping device for stamping thin sheet metal parts to overcome the shortcomings of the prior art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A stripping device for stamping thin sheet metal parts includes a stamping device body 1, a stamping telescopic device 2 for stamping is provided on the upper part of the stamping device body 1, a stamping table 3 is provided on one side of the stamping device body 1, a lower forming module 4 is provided on the upper part of the stamping table 3, an upper forming module 5 adapted to the lower forming module 4 is fixedly installed at the lower telescopic end of the stamping telescopic device 2, a positioning table 6 adapted to the upper forming module 5 is provided on the upper part of the lower forming module 4, a forming groove 7 adapted to the upper forming module 5 is provided at the bottom of the positioning table 6, a demolding telescopic device 8 with telescopic effect is provided inside the stamping device body 1, a bearing table 9 is fixedly installed at the upper telescopic end of the demolding telescopic device 8, a plurality of support seats 10 are provided on the upper part of the bearing table 9, an ejector column 11 is provided on the upper part of the support seat 10, a through hole 12 adapted to the ejector column 11 is provided through the bottom of the forming groove 7, and a clearance opening 13 adapted to the support seat 10 is provided on the upper part of the stamping table 3.

[0029] Specifically, when stamping thin sheet metal parts, the lower forming module 4 and upper forming module 5 of suitable size are replaced. The lower forming module 4 is fixedly installed on the upper part of the stamping table 3, and the upper forming module 5 is fixedly installed at the lower end of the stamping telescopic device 2. The positions of the lower forming module 4 and the upper forming module 5 are calibrated. The ejector post 11 is located at the through hole 12, and the size of the ejector post 11 does not affect the stamping effect of the metal part. Taking a rectangular metal part as an example, there are four ejector posts 11, which are distributed at the four corners of the rectangle. Setting them in this position makes it easier to remove the metal part after stamping. During stamping, the upper end of the ejector post 11 is flush with the bottom of the forming groove 7, and the metal to be stamped is placed in the groove. The part is placed on the positioning table 6 of the appropriate size. The stamping telescopic device 2 is activated. The telescopic end of the stamping telescopic device 2 drives the upper forming module 5 to move down. The protruding stamping block of the lower part of the upper forming module 5, which is adapted to the forming groove 7, squeezes the metal part into the forming groove 7. Then the metal part is pressed. After the stamping of the metal part is completed, the upper forming module 5 moves up. At this time, the demolding telescopic device 8 is activated. The telescopic end of the demolding telescopic device 8 drives the bearing table 9 to move up. The bearing table 9 drives several support seats 10 to move up. The support seats 10 move up at the clearance port 13. The support seats 10 drive the ejector column 11 to move up at the through hole 12. The ejector column 11 pushes the stamped metal part to move up, thereby achieving the effect of unloading the stamped metal part.

[0030] As a technical optimization of this utility model, the lower end of the ejector column 11 is provided with a first sliding block 14, the upper part of the support seat 10 is provided with a first sliding groove 15 adapted to the first sliding block 14, one end of the support seat 10 is rotatably connected to a first adjusting threaded rod 16 threadedly connected to the first sliding block 14, the side of the first adjusting threaded rod 16 is threadedly connected to a first limiting nut 17, the lower part of the support seat 10 is fixedly installed with a second sliding block 18, the upper part of the bearing platform 9 is provided with a plurality of second sliding grooves 19 adapted to the second sliding block 18, the side of the bearing platform 9 is rotatably connected to a plurality of second adjusting threaded rods 20 respectively threadedly connected to the corresponding second sliding block 18, and the side of the second adjusting threaded rod 20 is threadedly connected to a second limiting nut 21.

[0031] Specifically, when it is necessary to replace the lower forming module 4 and upper forming module 5 of different sizes, and the position of the through hole 12 cannot be aligned with the position of the ejector post 11, the first adjusting threaded rod 16 is rotated. When the first adjusting threaded rod 16 rotates, it drives the first sliding block 14 to slide in the first sliding groove 15. The first sliding block 14 drives the position of the ejector post 11 to move laterally. When the second adjusting threaded rod 20 rotates, it drives the second sliding block 18 to slide in the second sliding groove 19. The second sliding block 18 drives the support seat 10 to move, thereby adjusting the longitudinal position of the ejector post 11 and aligning the position of the ejector post 11 with the position of the through hole 12. Then, the first limiting nut 17 and the second limiting nut 21 are locked to limit and fix the position of the ejector post 11, thereby improving the applicability of this unloading structure.

[0032] As a technical optimization of this utility model, the ejector post 11 and the first sliding block 14 are detachably fixedly connected. The lower end of the ejector post 11 is threaded to the upper part of the first sliding block 14. A snap-fit ​​part 22 is provided on the lower side of the ejector post 11. The snap-fit ​​part 22 is polygonal. The ejector post 11 can be replaced according to the lower forming module 4 of different thicknesses. The lower end of the ejector post 11 is threaded to the upper part of the first sliding block 14 and is snapped into the snap-fit ​​part 22 by a wrench to tighten the ejector post 11, thereby improving the applicability of the device.

[0033] As a technical optimization of this utility model, the upper inner sidewall of the lower forming module 4 is provided with a guide angle 23, which makes it easy for the workers to place the metal parts to be stamped on the positioning table 6. Multiple sides of the lower forming module 4 are fixedly connected with fixed mounting plates 24. The fixed mounting plates 24 are fixedly installed on the upper part of the stamping table 3 by bolts, which makes it easy to install or replace the lower forming module 4. The upper forming module 5 can also be replaced. The stamping device body 1 has a maintenance window 25 through the opposite side, which communicates with the relief port 13. The position of the ejector column 11 can be adjusted or installed and replaced through the maintenance window 25.
