DETAILED DESCRIPTION

[0020] The product according to the present application is generally made of metal material, the metal material itself has certain toughness, when the external bending force is removed from the product, the bent product is easy to rebound, resulting in insufficient bending degree. The present application solves the problem by the way of secondary bending of the product.

[0021] The content of the present application will be further described in combination with specific embodiments:

[0022] For example, Figure 1 -Figure 4 As shown in the figure, a product bending device includes a base plate 1 and a bending driving assembly 2. The base plate 1 is provided with a side bending station and a secondary bending station 12. The bending driving assembly 2 includes a bending plate 21, the bending plate 21 is provided with a first bending part 22 and a second bending part 23 corresponding to the side bending station and the secondary bending station 12 respectively. The bending plate 21 is driven by a bending driver 24 to move, drive the first bending part 22 and the second bending part 23 to act, and make the product be bent for the first time and the second time in the side bending station 11 and the secondary bending station 12 respectively.

[0023] The side bending station 11 is provided with a first carrier 3, and the product needing to be bent for the first time is carried on the first carrier 3. The first carrier 3 is provided with a first stop block 31, and the product is placed on the side of the first stop block 31 facing the first bending part 22. In this embodiment, the first bending part 22 is configured as a roller with a vertical axis, and the first bending part 22 drives the middle part of the product to abut against the first stop block 31 under the driving of the bending driver 24, and then continues to move to bend the middle part of the product with the first stop block 31 as the center.

[0024] In some application scenarios, the product is not folded in half at its midpoint, but requires that the two ends of the bending have specified dimensions, i.e., one side is longer and the other side is shorter. Therefore, in this embodiment, an adjusting mechanism 4 is provided corresponding to the first carrier 3. The adjusting mechanism 4 includes an adjusting guide rail 42 fixed on the bending plate 21, and an adjusting block 41 slidingly arranged on the adjusting guide rail 42. A pair of adjusting blocks 41 slide perpendicular to the movement direction of the bending plate 21 and abut against the two end parts of the product on the first carrier 3 respectively. By sliding the pair of adjusting blocks 41, the position where the product on the first carrier 3 abuts against the first stop block 31 can be changed, thereby changing the bending point of the product.

[0025] After the product is bent by the first bending part 22 and reset, the product will have a certain degree of rebound phenomenon due to its own stress or elastic force, and the first bending part 22 moving in a straight line cannot give the product a larger deformation amount because it needs to avoid the first stop block 31.

[0026] Therefore, the second carrier 5 of the secondary bending station 12 is provided with a second stop block 51 and a symmetrically arranged bending clamp 52. The second stop block 51 has the same function as the first stop block 31, both of which abut against the product. One end of the bending clamp 52 is hinged to the second carrier 5, and the other end is a bending end. The bending end is inwardly buckled and configured as an arc. The second bending part 23 is configured as a roller with the same structure as the first bending part 22. The second bending part 23 rolls against the outer wall of the bending clamp 52, drives the bending clamp 52 to perform clamping action, and makes the bending clamp 52 abut against the product moved to the second carrier 5 and continue to bend the product.

[0027] The bending end of the bending clamp 52 is arranged in the recess to avoid the interference of the second stop block 51, and abuts against the two sides of the product after one-time bending, thereby giving the product a larger deformation amount.

[0028] In addition, the elastic member 53 is connected between the pair of bending clamps 52, and in the embodiment, the elastic member 53 is arranged as a spring. The elastic member 53 gives the bending clamps 52 a tendency to open, and the second carrier 5 is provided with the limiting block 54 corresponding to the bending clamps 52 to limit the opening angle of the pair of bending clamps 52.

[0029] When working:

[0030] 1. The product is placed on the first carrier 3, and the positions of the pair of adjusting blocks 41 abutting against the two ends of the product are adjusted according to the requirement, so that the position of the product to be bent abuts against the first stop block 31.

[0031] 2. The first bending part 22 is driven by the bending driver 24 to abut against the product, and the product is bent once.

[0032] 3. The product is taken off and placed on the second carrier 5.

[0033] 4. The second bending part 23 drives the bending clamp 52 to clamp the product and continue to bend, until the product is bent to the required angle.

[0034] The two different states of the product can be simultaneously operated in the one-time bending station 11 and the second-time bending station 12, respectively.

[0035] The above embodiment is only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and it cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
