The middle parts of the two opposite support columns 16 are respectively provided with a positioning block 18, and when the part 17 is placed on the frame 1, the part 17 can be positioned through the positioning blocks 18. The size of the frame 1 can be set as required, and the frame 1 can be made of a damping material so as to ensure that the frame 1 can be stable when the die is bent.
The upper die holder 13 and the lower die holder 3 are both mounted on the frame 1. The lower die holder 3 is provided with a groove 5 for inserting the upper die holder 13, the pre-bending part of the part 17 is positioned above the groove 5, and the upper die holder 13 is lifted in the groove 5 to press the pre-bending part and bend the part 17. The upper die holder 13 and the lower die holder 3 can be both conventional die holders, and the upper die holder 13 can be lifted by a hydraulic cylinder 14. The hydraulic cylinder 14 is arranged on the top plate 15, and the lower die holder 3 is arranged on the bottom plate 8. When the component 17 is bent, the upper die base 13 is lowered and presses the component 17 downward, so that the pre-bent portion is lowered in the groove 5 and is formed in the groove 5. The shape of the part 17 to be bent can be set according to the shapes of the groove 5 and the upper die holder 13, and a person skilled in the art can set the shape by adopting the existing structure.
The number of the guide mechanisms is at least two, and the two guide mechanisms are arranged on two sides of the lower die holder 3 and are installed on the frame 1. Each guide mechanism comprises two elastic pieces and two rollers 12, and the two rollers 12 correspond to the two elastic pieces respectively. The element 17 is arranged between the two rollers 12, and the top and the bottom of the element 17 are attached to the outer circumferences of the two rollers 12. One end of the elastic member is mounted on the frame 1, and each roller 12 is mounted on the other end of the corresponding elastic member.

The first spring 22 is arranged around the sliding shaft 20, and two ends of the first spring are respectively fixed on the bottom wall of the base 21 and the first sliding block 19. The first slide 19 is used for mounting the corresponding roller 12. The first sliding block 19 can slide along the sliding shaft 20 and simultaneously slide in the first sliding groove, so that the linear elastic action of the elastic part is ensured, the roller 12 can only move in the up-and-down direction, and the part 17 is prevented from deviating during bending.
In other embodiments, referring to fig. 2, the elastic member may include a mounting block 23, an elastic portion 24 connected to the mounting block 23, the mounting block 23 being used for mounting the corresponding roller 12, and the elastic portion 24 being mounted on the frame 1. The elastic part 24 has elasticity, so that the vibration of the part 17 during bending can be reduced, and meanwhile, the stress action of the part 17 during bending is reduced, so that other parts of the part 17 are kept in the original state, and the bending quality is improved.
In this embodiment, in each guide mechanism, one ends of two elastic member installation rollers 12 are detachably connected. The two elastic pieces can share the elasticity of the two elastic pieces in a detachable connection mode, so that the elastic action of the guide mechanism is enhanced, and the guide mechanism is selective and convenient to mount and use. Specifically, the two elastic members are connected by a detachable structure, and the detachable structure includes two insertion blocks 10 respectively disposed on the two elastic members, and at least one bolt 11 screwed into the two insertion blocks 10. When the user needs to enhance the overall elasticity of the guide mechanism, the user only needs to connect the two insertion blocks 10 through the bolts 11 to enable the two elastic pieces to form a whole, so that the elasticity of the upper elastic piece and the lower elastic piece is shared.
The number of the elastic expansion pieces is the same as that of the guide mechanisms, and each elastic expansion piece corresponds to one guide mechanism. The elastic expansion piece is in a natural expansion state, the expansion end of the elastic expansion piece is higher than the groove 5, and the elastic expansion piece is arranged on the frame 1. Each elastic expansion piece is arranged between the corresponding guide mechanism and the lower die base 3 and is positioned below the part 17. Specifically, the elastic telescopic piece comprises an L-shaped limit plate 2, a positioning shaft 6, a second spring 7 and a second sliding block 9. The limiting plate 2 is arranged on the frame 1 and forms a sliding groove II with the lower die base 3 in a surrounding mode, and the sliding groove II is used for the sliding block II 9 to slide up and down. The positioning shaft 6 is arranged on the limiting plate 2 and is positioned in the second sliding groove. The second spring 7 is arranged around the positioning shaft 6, and two ends of the second spring are fixed on the limiting plate 2 and the second sliding block 9 respectively. The second sliding block 9 is sleeved on the positioning shaft 6, and when the upper die holder 13 is not provided with the bent part 17, the height of the second sliding block 9 is higher than the depth of the groove 5. When the upper die holder 13 presses the part 17 downwards, the part 17 close to the two sides of the pre-bending part is pressed on the second sliding block 9 and continuously presses downwards on the upper die holder 13 to continuously press the part 17 on the second sliding block 9, and the second spring 7 can elastically push the second sliding block 9 upwards, so that the impact between the part 17 and the lower die holder 3 is relieved, and the friction between the part 17 and the lower die holder 3 is reduced.
When the die works, the upper die base 13 presses the pre-bending part of the part 17 downwards, the elastic expansion piece firstly contracts downwards under the stress action of the part 17 and continuously contracts to be flush with the top end of the lower die base 3, and the stress action of the part 17 at the opening of the groove 5 is preliminarily slowed down, so that the part 17 is protected; furthermore, when the elastic expansion piece contracts to the shortest, the elastic expansion piece cannot relieve the stress of the part 17, at the moment, the upper die base 13 presses the part 17 downwards, so that the part, far away from the pre-bending part, of the part 17 is stressed upwards, the roller 12 and the elastic piece can relieve the stress action of the part 17, the non-pre-bending part of the part 17 can be kept in an original shape when being bent, and meanwhile, the vibration of the part 17 can be reduced. Moreover, when the part 17 is placed in the mold, the roller 12 can reduce the friction of the part 17 and reduce the mold mark of the molded product.
The buffer pad 4 is arranged at the bottom of the groove 5, and when the upper die base 13 descends to the lowest, the bottom of the pre-bending part is pressed against the buffer pad 4. When the part 17 is bent and formed, the buffer pad 4 can reduce the impact between the pre-bent part of the part 17 and the bottom of the groove 5 of the lower die holder 3, and reduce the friction damage or impact damage of the part 17.
