Blank is bent the 4th again on the basis of " first angle+second angle+third angle " by three angles, the 4th forming punching head 240
Angle, final blank molding are " first angle+second angle+third angle+fourth angle " by curved angle.This segmentation
The bending of formula can make molding more accurate, avoid primary bending stress is excessive from causing yields low.As shown, the present embodiment
In, the 4th shaping channel is greater than or equal to 180 degree relative to the bending angle of the first shaping channel, and blank is finally bent 180 degree
More than, as shown in figure 14, in the present embodiment, blank is in the direction of arrows as shown in dotted line i, after brake forming for the original angle of blank
Bending is bent to dotted line ii from dotted line i to angle shown in dotted line ii, has been bent 180 degree.
From the upstream in the curved direction of blank to downstream, the first forming punching head 210, the second forming punching head 220, third molding
Formed punch 230 and the 4th forming punching head 240 are arranged successively, and are realized and are bent to the segmentation of blank, the first forming punching head 210 and the second one-tenth
The continuous bend to blank is realized in type formed punch 220, third forming punching head 230 and the 4th successively punching press of forming punching head 240.Blank
It is continuously curved in the first shaping channel, the second shaping channel, third shaping channel, the 4th shaping channel, 4 moldings is set
Channel (or more), segmentation carries out continuous bend to blank, can increase the curvature of blank final molding.Be arranged it is multiple at
Type channel, segmentation are bent blank, and blank continuous bend in shaping channel forms, and do not need alternating bending, production effect
Rate is high, while yields is high.
The phase each other of first shaping channel, the second shaping channel, third shaping channel, the 4th shaping channel in the present embodiment
Neighbour, but be not limited to the present embodiment, for example, separately have fifth forming channel between the first shaping channel and the second shaping channel, the 5th
Shaping channel is further bent relative to the bending direction of the first shaping channel or fifth forming channel is relative to the first molding
The back-flexing of the bending direction in channel.
In the present embodiment, the first mold pressing surface 301, the second mold pressing surface 302, third mold pressing surface 303,304 phase of the 4th mold pressing surface
Intersect, the second mold pressing surface 302 is further bent on the basis of the first mold pressing surface 301, and third mold pressing surface 303 is in the first mold pressing surface
It is bent on the basis of 301 into two steps, the 4th mold pressing surface 304 is further bent on the basis of third mold pressing surface 303, thus more preferably
Realization blank is bent.
As needed, the first mold pressing surface 301, the second mold pressing surface 302, third mold pressing surface 303, the 4th mold pressing surface can be designed
304 curvature and the first forming punching head 210, the second forming punching head 220, third forming punching head 230, the 4th forming punching head
240 pressing direction.For example, according to the first shaping channel, the second shaping channel, third shaping channel, the 4th shaping channel
Curvature is arranged the first forming punching head 210, second forming punching head 220, third forming punching head 230, the 4th forming punching head 240 and rushes
Direction is pressed, the pressing direction of the first forming punching head 210 and the pressing direction of the second forming punching head 220 intersect, the first forming punching head
210 pressing direction complies with the bending direction of blank in the first shaping channel, is bent blank conducive in the first shaping channel,
The pressing direction of second forming punching head 220 complies with the bending direction of blank in the second shaping channel, is conducive in the second shaping channel
It is interior to be bent blank.The case where third forming punching head 230, the 4th forming punching head 240, is similar, repeats no more.
Each technical characteristic of above embodiments can be combined arbitrarily, for simplicity of description, not to above-described embodiment
