Description

Technical Field

[0001] This utility model relates to the technical field of stamping forming feeding equipment, specifically a sheet metal stamping forming feeding device. Background Technology

[0002] In the field of sheet metal production, stamping is a widely used processing method that can efficiently and accurately process metal sheets into parts of various shapes. It is widely used in many industries such as automobile manufacturing, aerospace, and electronics.

[0003] A search revealed a patent, CN207447158U, which discloses a feeding device for stamping automotive sheet metal parts. The device includes a motor, and a microcontroller is located at the left end of the press, electrically connected to the motor. This feeding device allows for manual operation: pressing a button on an electric push rod retracts the push rod, raising the pressure plate to place the blank. Pressing another button returns the pressure plate to the bottom, where a rubber pad presses the blank firmly without damaging it. The simple press-and-release operation is straightforward. The motor automatically rotates the blank onto the lower die for stamping. During stamping, the rotating plate slides down along the rotating rod, preventing torque and deformation between the plate and the blank, thus improving stamping quality. After the upper die returns to its original position, the rotating plate returns to its original position under spring pressure. Then, the motor reverses, allowing for manual material changing. This eliminates the need for manual feeding, making it safer and more efficient.

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

[0005] The aforementioned comparative documents describe a process where the sheet metal part to be stamped is placed in a slot, and an electric push rod drives a pressure plate to press one side of the sheet metal part. The rotating plate, which holds the sheet metal part in place, is then rotated into the stamping device. The sheet metal part to be stamped needs to be manually aligned with the lower die before stamping. After stamping, the rotating plate is rotated out, and the electric push rod drives one end of the pressure plate away from the stamped sheet metal part. Then, the sheet metal part to be stamped is placed again. The above method of stamping the sheet metal part is cumbersome and reduces the efficiency of the stamping feeding device. Therefore, there is an urgent need in the art to improve the sheet metal stamping forming feeding device to overcome the shortcomings of the prior art. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Example 1

[0028] Please see Figures 1-5 A sheet metal stamping feeding device includes a rotating column 2 located on one side of a stamping body 1. The rotating column 2 is adapted to the position of a stamping table 3 on the stamping body 1. The stamping body 1 has an upper die that moves up and down and a lower die that is fixedly installed on the stamping table 3. The lower part of the rotating column 2 has a support plate 4 that is fixedly installed on the side of the stamping body 1. The rotating column 2 is rotatably connected to the upper part of the support plate 4. A drive motor 5 for driving the rotating column 2 to rotate intermittently is fixedly installed on the lower part of the support plate 4. The side of the rotating column 2 has several feeding racks 6 that are adapted to the lower die. The cavity inside the feeding rack 6 is adapted to the outer side of the lower die. The upper part of the feeding rack 6 has a positioning step 7 that is adapted to the sheet metal part to be stamped. A connecting plate 8 is fixedly installed on one side of the feeding rack 6. A sliding seat 9 is fixedly installed on the side of the connecting plate 8 away from the feeding rack 6. Multiple sides of the rotating column 2 have sliding grooves 10 that are adapted to the sliding seat 9. A first spring 11 located below the sliding seat 9 is provided in the sliding groove 10.

[0029] In this embodiment, the specific implementation is as follows: When stamping a sheet metal part, a feeding rack 6 adapted to the sheet metal part is installed on the side of the rotating column 2. The sheet metal part is placed at the positioning step 7 of the appropriate size. The drive motor 5 is started by the control switch. The output end of the drive motor 5 drives the rotating column 2 to rotate, and the rotating column 2 drives the feeding rack 6 to rotate. The feeding rack 6, with the sheet metal part to be stamped on it, moves to the top of the lower die. The drive motor 5 stops, and the stamping body 1 is opened to drive the upper die to move down. When the upper die moves down, it first contacts the sheet metal part to be stamped and the feeding rack 6. The upper die pushes the feeding rack 6 and the sheet metal part to be stamped down. The feeding rack 6 drives the sliding seat 9 down through the connecting plate 8. At this time, the first spring 11 is compressed. The upper die continues to move down and cooperates with the lower die to complete the stamping of the sheet metal part. The feeding rack 6 moves down to the side of the lower die, and the middle position of the sheet metal part to be stamped is stamped. After the stamping is completed, the side of the stamped sheet metal part is still in the position of the positioning step 7. After the stamping is completed, the upper die moves upward, and the feeding rack 6 is no longer pressed by the upper die. The tension of the first spring 11 pushes the sliding seat 9 to move upward. The sliding seat 9 drives the feeding rack 6 to move upward, and the positioning step 7 pushes the side of the stamped sheet metal part to move upward. During the stamping process, the operator places the sheet metal part to be stamped on the positioning step 7 on another feeding rack 6. After the stamping is completed, the drive motor 5 is started again. The drive motor 5 drives the rotating column 2 to rotate. Then the stamped sheet metal part is removed and the sheet metal part to be stamped is placed again. By setting up several feeding racks 6, and by driving the rotating column 2 through the drive motor 5 to drive several feeding racks 6 to rotate intermittently, the effect of stamping and loading and unloading at the same time is achieved, which improves the feeding efficiency of the stamping feeding device, and thus improves the efficiency of the overall stamping equipment in stamping and forming sheet metal parts.

[0030] Example 2

[0031] Please see Figure 1 and Figure 3 This embodiment includes the above embodiment, and further includes: a first guide limiting post 12 is fixedly installed at the bottom of the sliding groove 10, the first guide limiting post 12 passes through the sliding seat 9, the first spring 11 is sleeved on the side of the first guide limiting post 12, the sliding groove 10 passes through the upper part of the rotating post 2, and the sliding seat 9 is in a T shape that matches the sliding groove 10.

[0032] In this embodiment, the first guide limiting post 12 passes through the sliding seat 9 and limits the movement of the sliding seat 9. The first spring 11 is sleeved on the side of the first guide limiting post 12. The first guide limiting post 12 prevents the first spring 11 from undergoing radial deformation. When different sheet metal parts need to be stamped, the sliding groove 10 passes through the upper part of the rotating post 2. The sliding seat 9 can be removed by moving the sliding seat 9 upward. The installation can be completed by inserting the appropriate feeding rack 6 into the sliding groove 10 through a plug-in method. This facilitates the installation or later replacement of the feeding rack 6. The sliding seat 9 is T-shaped to fit the sliding groove 10, which improves the stability of the feeding rack 6.

[0033] Example 3

[0034] Please see Figure 4 and Figure 5 This embodiment includes all the above embodiments, and further includes: a plurality of second guide limiting posts 13 located on the side of the lower die are fixedly installed on the stamping table 3; a plurality of guide holes 14 adapted to the second guide limiting posts 13 are opened through the feeding rack 6; a moving ring 15 is sleeved on the side of the second guide limiting post 13; a second spring 16 is provided at the lower part of the moving ring 15; the second spring 16 is sleeved on the side of the second guide limiting post 13; the upper end of the second guide limiting post 13 extends beyond the upper part of the lower die; and the upper end of the second guide limiting post 13 is provided with an inclined guide angle 17.

[0035] In this embodiment, the lower part of the feeding rack 6 is higher than the upper part of several second guide limiting posts 13 when it is not pressed down. When the lower die moves down to press down on the feeding rack 6, the guide hole 14 is sleeved on the side of the second guide limiting post 13. The feeding rack 6 is limited by the second guide limiting post 13, so that the feeding rack 6 moves more accurately on the side of the lower die, improving the stamping accuracy of the sheet metal parts. The guide angle 17 facilitates the insertion of the second guide limiting post 13 into the guide hole 14. When the feeding rack 6 moves down, it applies pressure to the second spring 16. When the moving ring 15 moves down, the second spring 16 contracts. After the upper die moves up, the tension of the second spring 16 pushes the feeding rack 6 up, improving the stability of the feeding rack 6 when it moves up. At the same time, it prevents the sheet metal parts from getting stuck in the lower die position, which would make it difficult for the first spring 11 to return to its original position, thus improving the feeding effect.
