[0026] To make the purpose, technical solution and advantages of the implementation of the present invention clearer, the present invention will now be further described in detail with reference to the accompanying drawings and the following embodiments, so that the public can better master the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0027] An automatic feeding and bending device, including a bracket 1, two rotating rollers 2 are symmetrically arranged inside the bracket 1, above the two rotating rollers 2, a die head 3 is arranged in a lifting structure manner, and the die head 3 is connected with a vertical power mechanism; on the upper end surface of the bracket 1, a mounting plate 4 is fixedly arranged, and a reinforcing brace 22 is arranged between the bracket 1 and the mounting plate 4 to ensure the stability of the mounting plate 4. A bending opening is provided at the position above the two rotating rollers 2 on the mounting plate 4. On the upper end surface of the mounting plate 4, a push plate 5 is arranged in a sliding structure manner, and the push plate 5 is connected with a horizontal power mechanism. The mounting plate 4 is provided with a limiting plate 6 in a fixed structure manner. A sliding groove 7 for the push plate 5 to slide is provided on the lower end surface of the limiting plate 6, and a material guiding groove 8 is provided on the upper end surface of the limiting plate 6. The material guiding groove 8 is communicated with the sliding groove 7; on the upper end surface of the limiting plate 6 on one side of the die head 3, a blocking member 9 is fixedly arranged, and a storage bin 10 communicated with the material guiding groove 8 is fixedly arranged on the upper end surface of the limiting plate 6. The storage bin 10 is located on the side of the blocking member 9 away from the die head 3. The material plate is stored in the storage bin 10 to reduce the occupation of space, and then the push plate 5 is used to push the material plate falling into the material guiding groove 8 to the bending opening for bending work, and the structure is simple.

[0028] It should be noted that the vertical power mechanism is a hydraulic press. The automatic feeding and bending device is arranged on the operating table of the hydraulic press, and the output end of the hydraulic press is connected with the die head 3.

[0029] Specifically, a connecting plate 11 is fixedly arranged at the output end of the hydraulic press, and the connecting plate 11 is connected with the die head 3 in a fixed structure manner; the horizontal power mechanism includes an upper connecting rod 12 connected to the connecting plate 11 at an obtuse angle. A support leg 13 is arranged below the upper connecting rod 12, and the support leg 13 is fixedly connected with the push plate 5. When the upper connecting rod 12 moves downward, the push plate 5 is driven to move outward through the support leg 13; a return spring 14 is arranged on one side of the support leg 13, and the other end of the return spring 14 is connected with the mounting plate 4 or the limiting plate 6 to realize that when the upper connecting rod 12 moves upward, the push plate 5 is reset under the spring tension.

[0030] It should be elaborated that the two support legs 13 are respectively connected with the push plate 5, and rollers 15 cooperating with the upper connecting rod 12 are rotatably arranged on the outer sides of the support legs 13, making the cooperation more smooth.

[0031] It should be indicated that a mounting seat 16 is fixedly arranged on the connecting plate 11. The mounting seat 16 is provided with a vertical groove, and a connecting piece 17 is slidably arranged in the vertical groove. One end of the connecting piece 17 is provided with a nut through a threaded engagement manner, and the other end of the connecting piece 17 is connected with the upper connecting rod 12 through a hinged structure manner. By adjusting the position relationship between the connecting piece 17 and the mounting seat 16 through the vertical groove, the included angle between the connecting rod 12 and the connecting plate 11 is adjusted, and further the moving speed of the push plate 5 is adjusted.

[0032] It should be noted that, such as Figure 2As shown, the thickness of the push plate 5 is less than that of the material plate. When the material plate is on the upper end surface of the push plate 5, the push plate 5 moves, and the material plate in the storage bin 10 is blocked by the blocking member 9 and cannot move.

[0033] On the basis of the above embodiments, in another embodiment, a lower connecting rod 18 is arranged on one side of the connecting plate 11 away from the upper connecting rod 12 in a hinged structure manner. The other end of the lower connecting rod 18 is provided with a push rod 19 in a hinged structure manner. The push rod 19 is provided with a guide rail 20 in a sliding structure manner. The guide rail 20 is connected to the bracket 1 in a fixed structure manner. The finished product is pushed out and unloaded in the bracket 1 by using the push rod 19. A reverse U-shaped frame 21 for limiting the position of the push rod 19 is arranged on one side of the bracket 1 to ensure the connection relationship between the push rod 19 and the guide rail 20.

[0034] The working principle and process of the present utility model are as follows:

[0035] First step, stack the material plates in the storage bin 10.

[0036] Second step, start the hydraulic press. The output end of the hydraulic press drives the connecting plate 11, the die head 3, the upper connecting rod 12 and the lower connecting rod 18 to move downward. The upper connecting rod 12 drives the push plate 5 to move to the left through the roller 15 and the support leg 13. When the right end of the push plate 5 moves to the right side of the storage bin 10, the material plate falls onto the upper end surface of the mounting plate 4, and the lower connecting rod 18 pushes the push rod 19 to move to the right.

[0037] Second step, when the output end of the hydraulic press moves upward, the return spring 14 pulls the push plate 5 to move to the right through the support leg 13, and then pushes the material plate to the bending opening; the lower connecting rod 18 pulls the push rod 19 to move to the left, and repeat the second step for bending work.
