[0025] 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] Example 1

[0027] See also Figure 1-Figure 7A mold forming continuous flanging and bending feeding mechanism includes an upper mold base 1 and a lower mold base 2. The lower surface of the upper mold base 1 is fixedly installed on the upper mold forming block 3. The upper surface of the lower mold base 2 is provided with a lower mold forming block 5. The lower surface of the upper mold base 1 is provided with an upper mold pressing plate 4. An elastic member 6 with elasticity is provided between the upper mold pressing plate 4 and the lower surface of the upper mold base 1. A workpiece 9 is placed on the lower mold forming block 5. The upper mold forming block 3 and the lower mold forming block 5 are staggered and the horizontal distance between the two is adapted to the workpiece 9. The lower mold base 2 is provided with a first adjustment unit 7 for adjusting the position of the lower mold forming block 5.

[0028] Specific implementation method in this embodiment: In this embodiment, a new structure of continuous die waste-free flanging bending feeding is used to achieve waste-free flanging bending, without adding a notch cutting process, such as Figure 7 As shown, in the prior art, when the workpiece 9 is subjected to flanging bending with waste material, it is necessary to first punch a notch on the workpiece 9, while in this embodiment, the flanging bending operation is performed directly on the side of the workpiece 9, thereby achieving the goal of improving production efficiency and reducing costs; in this embodiment, when the workpiece 9 is subjected to flanging bending, the workpiece 9 to be flanging is placed on the upper surface of the lower die forming block 5, and the upper die holder 1 is controlled to move downward by operating the external driving device. Figure 2 The upper die pressing plate 4 shown presses the workpiece 9, the upper die base 1 continues to move downward, and the upper die pressing plate 4 stops moving downward. At this time, the elastic member 6 is compressed, and the upper die forming block 3 continues to move downward. The upper die forming block 3 cooperates with the lower die forming block 5 to perform flange bending on the side of the workpiece 9. The position of the lower die forming block 5 on the lower die base 2 can be adjusted by the first adjustment unit 7, and continuous waste-free flange bending can be performed on workpieces 9 of different thicknesses, thereby improving the applicability of the overall device.

[0029] Example 2

[0030] See also Figure 1-Figure 4 , this embodiment includes the above embodiment, which further includes: the first adjusting unit 7 includes a first sliding seat 10 fixedly connected to the lower side of the lower mold forming block 5, and the upper surface of the lower mold base 2 is provided with a first sliding groove 11 adapted to the first sliding seat 10, and a first adjusting screw rod 12 is rotatably connected in the first sliding groove 11, the first adjusting screw rod 12 passes through the first sliding seat 10 and is threadedly connected to the first sliding seat 10, one end of the first adjusting screw rod 12 extends to the outside and a first limiting ring 14 is threadedly connected to its side, the first adjusting screw rod 12 is fixedly connected to the first rotating ring 13 at one end located on the outside, and the first rotating ring 13 is rotatably connected to the first turning handle 15 on the side away from the first adjusting screw rod 12.

[0031] The specific implementation method in this embodiment is as follows: when it is necessary to adjust the position of the lower mold forming block 5, the first rotating ring 13 is rotated by holding the first turning handle 15, and the first rotating ring 13 drives the first adjusting screw 12 to rotate. When the first adjusting screw 12 rotates, it drives the first sliding seat 10 to move in the first sliding groove 11, and the first sliding seat 10 drives the position of the lower mold forming block 5 to move. After the position of the lower mold forming block 5 is adjusted, the first limiting ring 14 is tightened to limit and fix the position of the first adjusting screw 12, so as to facilitate the adjustment and fixation of the position of the lower mold forming block 5.

[0032] Implementation Three

[0033] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , this embodiment includes all the above embodiments, which further includes: a hanging plate 16 with an L-shaped cross-section is provided on the lower surface of the upper mold base 1, and a second adjusting unit 8 for adjusting the position of the hanging plate 16 is provided on the lower surface of the upper mold base 1. The second adjusting unit 8 includes a second sliding seat 17 fixedly mounted on the upper side of the hanging plate 16, and a second sliding groove 18 adapted to the second sliding seat 17 is opened on the lower surface of the upper mold base 1. A second adjusting screw rod 19 with one end extending to the outside is rotatably connected in the second sliding groove 18, and the second adjusting screw rod 19 passes through the second sliding seat 17 and is threadedly connected to the second sliding seat 17. The end of the second adjusting screw rod 19 located on the outside is fixedly connected to a second rotating ring 22, and the second rotating ring 22 is rotatably connected to a second handle 23 on the side away from the second adjusting screw rod 19. The side of the end of the second adjusting screw rod 19 located on the outside is threadedly connected to a second limiting ring 21.

[0034] The specific implementation method of this embodiment: the hanging plate 16 can drive the upper mold pressing plate 4 to move upward, and the hanging plate 16 can also support the other side of the workpiece 9 to ensure the horizontality of the workpiece 9 when flanging and bending the workpiece 9. Since the sizes of the workpieces 9 that need to be flanging and bent are different, it is necessary to adjust the position of the hanging plate 16. When the position of the hanging plate 16 needs to be adjusted, the adapted hanging plate 16 is rotated so that it can move the upper mold pressing plate 4 upward. By holding the second turning handle 23 and rotating the second rotating ring 22, the second rotating ring 22 drives the second adjusting screw 19 to rotate. When the second adjusting screw 19 rotates, it drives the second sliding seat 17 to move in the second sliding groove 18. When the second sliding seat 17 moves, it drives the hanging plate 16 to move. After adjusting the position of the hanging plate 16 to the position adapted to the workpiece 9, tighten the second limiting ring 21 to limit and fix the position of the second adjusting screw 19, thereby improving the applicability of the overall device.

[0035] Implementation Four

[0036] See also Figure 1-Figure 4 and Figure 6 This embodiment includes all the above embodiments, which further includes: the upper surface of the upper mold pressing plate 4 is fixedly connected to the upper mold inner guide column 24, the upper end of the upper mold inner guide column 24 is passed through the upper mold base 1, the elastic member 6 is a nitrogen spring, and the lower part of the upper mold forming block 3 close to the lower mold forming block 5 is rotatably connected to the guide extrusion roller 20.

[0037] Specific implementation method in this embodiment: The mold-specific nitrogen spring is a new type of elastic component with high-pressure nitrogen as the working medium. It is small in size, large in elasticity, long in stroke, stable in operation, precisely manufactured, long in service life (one million times), with a flat elasticity curve, and no need for pre-tightening, etc. Therefore, the above-mentioned elastic member 6 adopts a nitrogen spring. When the upper mold pressing plate 4 presses the workpiece 9 and the upper mold base 1 continues to move downward, the upper end of the guide column 24 in the upper mold moves in the upper mold base 1 to limit the position of the upper mold pressing plate 4. When the upper mold forming block 3 continues to move downward, the guide extrusion roller 20 first contacts the workpiece 9. The guide extrusion roller 20 can rotate and squeeze the edge of the workpiece 9 to prevent the upper mold forming block 3 from scratching the surface of the workpiece 9.
