Movement compresses plate 5.When carrying out flanging forming to plate 5, plate 5 is placed on 4 top of flanging die first, makes one section
Plate is used for flanging forming beyond flanging die 4, and side and 2 cooperating of flange cavity plate of flanging die 4 carry out plate flange
Forming；Secondly it is moved to close to the direction for going out flanging die 4 in the driving lower flange cavity plate 2 of upper die holder 1 and material pressing core 3, works as pressure
When material core 3 moves to the position of plate 5 and is pressed on plate 5 on flanging die 4,3 stop motion of material pressing core, flange cavity plate 2
Continue to move, pre- turn-up portion 21, which is first contacted with plate 5, makes plate 5 be bent, and hereafter flange forming part 22 is contacted with plate 5 makes plate
5 are bent again.
Preferably, the top of flange cavity plate 2 is slidably connected by sliding rail 11 and upper die holder 1, and 2 side of flange cavity plate passes through spiral shell
Column 12 is connect with upper die holder 1, and one end of stud 12 is fixedly connected on flange cavity plate 2, and the other end of stud 12, which is equipped with, adjusts hand
Handle 121, stud 12 pass through upper die holder 1, stud 12 to be furnished with locking nut 122, and locking nut 122 is in the outside of upper die holder 1.Rotation
Regulation handle 121 can be such that flange cavity plate 2 is slided along sliding rail 11, realize the variation of distance between flange cavity plate 2 and flanging die 4.
It is locked by locking nut, the distance between flange cavity plate 2 and flanging die 4 can be adjusted according to the variation of 5 thickness of plate,
To carry out flanging forming suitable for the plate to different-thickness, the applicability of the flanging die is enhanced；In addition, diel is long
Time, the flanging die had certain wear extent using flange cavity plate 2 for a long time, so as to cause turning over using also will produce abrasion
The distance between edge die 2 and flanging die 4 become larger, and cause the dimensional accuracy in flanging forming inaccurate, while can also weaken
The intensity of product；The dimensional accuracy of stamping parts generally ensures by mould and die accuracy, so the moment is wanted to ensure the precision ability of mold
Ensure the quality of product.When flange cavity plate 2 is worn, and the distance between flange cavity plate 2 and flanging die 4 become larger, pass through rotation
Turning regulation handle 121 makes flange cavity plate 2 be slided along sliding rail 11 to adjust the distance between flange cavity plate 2 and flanging die 4, with full
Sufficient technology requirement, is locked finally by locking nut.The utility model can pass through adjusting when flange cavity plate 2 has abrasion
Self-compensation situation is carried out, the service life of flanging die is extended.
In the first embodiment of the utility model, above-mentioned pre- turn-up portion 21 includes inclined surface I 211 and and flanging die
The parallel vertical plane I 212 of 4 working face, flange forming part 22 are the vertical plane II 221 parallel with the working face of flanging die 4,
Vertical plane II 221 is connect by inclined surface I 211 with vertical plane I 212, and the distance of vertical plane I 212 to 4 working face of flanging die is big
The distance of 4 working face of flanging die is arrived in vertical plane II 221.Pre- turn-up portion 21 is arranged in the lower section of flange forming part 22.
It is preferred that pre- turn-up portion 21 and flange forming part 22 are an integral molding structure, the setting of pre- turn-up portion 21 is molded in flange
The lower section in portion 22, pre- turn-up portion 21 and the junction of flange forming part 22 pass through I 211 transition of inclined surface.The present embodiment is carrying out

Pre- turn-up portion 21 is first contacted with plate 5, and flange cavity plate 2, which continues to move downward pre- turn-up portion 21, makes the generation flexural deformation of plate 5, shape
At larger bending radius；The beginning of second stage flange forming part 22 is contacted with plate 5, and flange cavity plate 2, which continues to move downward, to be turned over
Edge forming portion 22 makes plate 5 further be bent, and small bending radius is formed by first stage larger bending radius, until reaching
To the requirement of plate flange.
In second of embodiment of the utility model, above-mentioned pre- turn-up portion 21 is inclined surface II 213, flange forming part 22
For the vertical plane II 221 parallel with the working face of flanging die 4, inclined surface II 213 is to the direction far from 4 working face of flanging die
It tilts.It is preferred that pre- turn-up portion 21 and flange forming part 22 are an integral molding structure, pre- turn-up portion 21 is arranged in flange forming part 22
Lower section.When the present embodiment carries out flanging forming, the bending of progressive form is changed to Lai real by the direct bending forming of traditional technology
Existing flanging forming, since pre- turn-up portion 21 is inclined surface II 213, pre- turn-up portion 21 move downward first with before metal blank 5
End in contact moves closer to 5 rear end of plate as flange cavity plate 2 continues pushing, and flange forming part 22 is contacted with plate 5.Flange
Cavity plate 2 completes overturning process after pressing down, and overcomes plate flange to spring back with this, the defect of outer warpage.
Stamping parts flangikng is changed to by the direct bending forming of traditional technology through two stages by the utility model
Flanging forming (or be changed to the bending of progressive form to realize flanging forming) is realized in bending, the substantially bending of the process+whole
The effect of shape, overcome high-strength steel flange rebound, warpage the defects of, ensure that the precision and quality of stamping parts.The utility model
The novel flanging die provided has the features such as simple in structure, easy to use, to inhibit sheet metal parts rebound with obvious effects, is suitable for
The flanging forming of automotive sheet stamping parts.
The utility model is exemplarily described above in association with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the improvement of the various unsubstantialities of technical solutions of the utility model progress is used, or without changing
Directly apply to other occasions by the design of the utility model and technical solution, the scope of protection of the utility model it
It is interior.
