Under the condition, through the arrangement of the gasket, the adjustment of the displacement of the upper die inclined block in the first bending direction can be realized more conveniently and effectively, the adjustment of the gap between the bending inner module and the bending upper module along the second bending direction is finally realized, the displacement of the upper die inclined block relative to the upper template after the displacement adjustment is prevented through the fixation of the fastening screws, and the reliability and the effectiveness of the gap adjustment between the bending inner module and the bending upper module are improved.
In addition, in the present embodiment, the shape and size of the spacer 16 are not particularly limited, and may be set according to the size of the adjustment distance. In some examples, the thickness dimension of the shim 16 may be 0mm to 10mm, such as 3.00mm, 5.00mm, or 8.00mm, among others. In other examples, the thickness dimension of the shim 16 may be 0mm to 2mm, such as 1.00mm, 1.50mm, or 1.75mm, among others. Therefore, the height adjustment size (the first bending direction) of the upper inclined block can be calculated according to the size of the gap (the second bending direction) which needs to be adjusted between the bending inner module and the bending upper module, so that the adjustment is performed through the setting of the matching thickness size of the gasket, and the adjustment of the gap between the bending inner module and the bending upper module is realized.
In this embodiment, one of the working principles of the bending die may be as follows: placing a product (such as a sheet metal part 3) on the bending inner module 22, wherein during die assembly, the upper die inclined block 13 moves downwards to push the lower die inclined block 23 to move rightwards, a connecting rod 43 connected with the lower die inclined block 23 presses a spring 41 rightwards, the spring 41 is compressed to store energy, meanwhile, the lower die inclined block 23 moves rightwards to drive the bending inner module 22 to move rightwards, the bending upper module 12 moves downwards to be matched with the bending inner module 22 at a specific position, and thus the sheet metal part 3 is bent to form a bending part 31 of the sheet metal part 3; after the bending is formed, when the die is opened, the upper die inclined block 13 and the upper bending module 12 move upwards, the acting force exerted on the lower die inclined block 23 by the upper die inclined block 13 is cancelled, the lower die inclined block 23 moves leftwards under the action of the pushing force of the stored energy spring 41 and drives the inner bending module 22 to move leftwards, so that the part of the inner bending module 22 is separated from the sheet metal part 3 to withdraw from the inner flanging 32 of the sheet metal part 3, and the sheet metal part 3 is convenient to take out.
As described above, when the sheet metal part 3 is bent and formed, and the bending effect of the sheet metal part 3 is not satisfactory, for example, when the gap between the bending upper module 12 and the bending inner module 22 is too large, the bending degree of the sheet metal part 3 is insufficient, or when the gap between the bending upper module 12 and the bending inner module 22 is too small, the sheet metal part 3 is bent, the surface is pressed and stamped or scratched, and the like, and the gap between the bending upper module 12 and the bending inner module 22 can be adjusted by adjusting the displacement of the upper die inclined block 13 in the first bending direction 5 (for example, the up-down direction). Specifically, the adjustment manner thereof is not particularly limited. For example, the adjustment can be performed by the adjusting screw 14, or for example, the adjustment can be performed by the gasket 16, the upper die inclined block 13 is stably mounted on the upper die plate 11 by the adjusting screw 14 or the gasket 16, and then the fastening screw 15, so that the vertical height adjustment of the upper die inclined block 13 in the first bending direction 5 (vertical direction) is realized, and thus, when the die is closed, the displacement of the lower die inclined block 23 in the second bending direction 6 (horizontal direction) can be correspondingly adjusted, that is, the displacement of the bending inner module 22 in the second bending direction 6 (horizontal direction) is also adjusted, so that the adjustment of the gap between the bending upper module 12 and the bending inner module 22 is realized, and the sheet metal part 3 formed by bending can have a sufficient bending degree and is not easily scratched or scratched.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention will be apparent to those skilled in the art from this description.
