[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-6 A flanging device for automotive stamping parts includes a lower pressing core 1, a lower die base 2, and an upper pressing core 3. The lower pressing core 1 is fixedly connected to the lower die base 2 at its bottom end. The lower die base 2 is located directly below the lower pressing core 1. Multiple support columns 23 are installed on both sides of the top of the lower die base 2. A rotating shaft 24 is rotatably connected to the right side of the lower die base 2 via a rotating groove on a rotating shaft base 21. A placement groove 11 is provided at the top of the lower pressing core 1. A stamping part 12 is placed at the top of the placement groove 11. The length of the stamping part 12 is greater than the length of the placement groove 11, so that the left and right ends of the stamping part 12 extend beyond the left side of the lower pressing core 1 and the right side of the rotating shaft 24 by a certain distance.

[0017] An upper pressure core 3 is set directly above the top of the lower pressure core 1. An arc-shaped groove 31 is opened on the right side of the upper pressure core 3. The heights of the two sides of the upper pressure core 3 are not the same, with the height on one side of the arc-shaped groove 31 being greater than the height on the other side. The top left and right sides of the upper pressure core 3 are connected to the upper mold base 33 through the second cylinder 32. The output end of the second cylinder 32 contacts the inner top plate of the upper mold base 33. The top left and right sides of the upper mold base 33 are moved and limited to the outside of the support column 23 through multiple mounting grooves 34. The mounting grooves 34 penetrate through both sides of the upper mold base 33.

[0018] A connecting block 26 is fixedly installed on the bottom of the surface of the rotating shaft 24. The bottom of the connecting block 26 is rotatably connected to the output end of the first cylinder 25. The first cylinder 25 is fixed on the right side of the top of the lower mold base 2 through the fixed base 22. The first cylinder 25 and the lower mold base 2 are in a horizontal position relationship. A guide plate 27 is fixedly connected to the top of the rotating shaft 24. The bottom of the guide plate 27 contacts the top of the rotating shaft base 21. Limiting plates are fixedly installed on both sides of the rotating shaft base 21 extending to both sides of the rotating shaft 24.

[0019] A side-flanging blade 35 is fixedly installed on the bottom left side of the upper mold base 33. The side-flanging blade 35 is located outside the upper pressure core 3. A fixing plate 36 is fixedly installed on the inner right side of the upper mold base 33. A trolley blade 38 is slidably connected to the fixing plate 36 through a sliding groove 37. The bottom end of the trolley blade 38 contacts the top end of the guide plate 27 on the rotating shaft 24. The output end of the third cylinder 39 is connected to the right side of the trolley blade 38. The third cylinder 39 is fixedly installed on the inner right side of the upper mold base 33. The third cylinder 39 is located below the fixing plate 36, and the trolley blade 38 is L-shaped.

[0020] In this embodiment, when in use, the lower die base 2 is fixedly placed in one place, and the device is started. At this time, the upper die base 33 moves upward on the surface of the support column 23 through the mounting groove 34 on both sides. The upper die base 33 drives the upper pressure core 3 to move upward through the second cylinder 32, so that the bottom end of the upper pressure core 3 is away from the bottom end of the lower pressure core 1. When it moves to a certain distance, the upper die base 33 stops moving upward. At this time, the manipulator places the stamping part 12 to be turned into the placement groove 11 at the top of the lower pressure core 1. The left and right ends of the stamping part 12 extend beyond the left side of the lower pressure core 1 and the right side of the rotating shaft 24 by a certain distance. The placement groove 11 initially limits the stamping part 12.

[0021] At this time, the robotic arm retracts, the upper mold base 33 moves downward, driving the upper pressure core 3 to move downward. At this time, the bottom end of the upper pressure core 3 contacts the top end of the stamping part 12 and forms a downward pressure on the stamping part 12, limiting and fixing the stamping part 12. At this time, the upper pressure core 3 located on one side of the arc groove 31 will move downward, driving the right side of the stamping part 12 to move downward. At this time, as the upper pressure core 3 moves downward, the right side of the stamping part 12 is flanged on the arc surface at the top end of the rotating shaft 24. The arc groove 31 and the arc at the top end of the rotating shaft 24 form an arc-shaped flanging on one side of the stamping part 12. At this time, the second cylinders 32 on both sides of the top end of the upper pressure core 3 drive the upper mold base 33 to move downward. The upper mold base 33 drives the side flanging knife 35 at the bottom end to move downward, so that the bottom end of the side flanging knife 35 contacts the left side of the stamping part 12, and the side flanging knife 35 performs an L-shaped flanging on the left side of the stamping part 12.

[0022] At this time, the third cylinder 39 on the inner wall of the upper mold base 33 will move forward. The output end of the third cylinder 39 will drive the vertical part of the trolley cutter 38 to move forward in the slide groove 37 in the fixed plate 36. The horizontal part of the trolley cutter 38 will move at the top of the guide plate 27 on the rotating shaft 24. When it moves to a certain distance, the top of the horizontal part of the trolley cutter 38 will contact the right side of the stamped part 12 that has been flanged, and drive the stamped part 12 to move forward along the arc edge of the rotating shaft 24 on the rotating shaft base 21, and perform U-shaped flanging on the right side of the stamped part 12.

[0023] After the right side of the stamped part 12 is stamped and flanged, the third cylinder 39 drives the trolley cutter 38 to move backward to the end through the slide groove 37, so that the horizontal part of the trolley cutter 38 moves away from the outside of the guide plate 27. Then, the upper die base 33 moves upward through the support column 23, so that the bottom end of the upper pressure core 3 moves upward away from the top of the stamped part 12, and drives the trolley cutter 38 and the side flange cutter 35 to move upward. At this time, the first cylinder 25 in the lower die base 2 moves backward. Since the output end of the first cylinder 25 is rotatably connected to the bottom end of the connecting block 26 at the bottom end of the rotating shaft 24 through the connecting column, when the top end of the rotating shaft 24 is connected to the bottom end of the lower die base 2, the first cylinder 25 in the lower die base 2 moves backward. When the mold base 2 is parallel, the connecting block 26 is located to the left of the rotating shaft 24, and the connecting block 26 is not perpendicular to the lower mold base 2. Therefore, when the first cylinder 25 is started, the output end of the first cylinder 25 drives the connecting block 26 to rotate within a small range through the connecting column. When the connecting block 26 is perpendicular to the lower mold base 2, the connecting block 26 drives the arc-shaped area of ​​the rotating shaft 24 to rotate along the rotating shaft base 21 to below the stamping part 12, thus not interfering with the picking up of the stamping part 12. At this time, the stamping part 12 is picked up from the top placement groove 11 of the lower pressing core 1 by the robot arm and then sent to the next processing area. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
