Face, and third flanged plate 62 is rectangular loop configuration；Under second upper die structure 6 and 5 molding state of lower die structure, institute
Lower face the first outer side edges 31 of pushing for stating third flanged plate 62 are set.
Second upper die structure 6 further includes several rotations and pulls mechanism 64, and several rotations pull mechanism 64 the
Be respectively divided into four plate faces of the surrounding of three flanged plates 62 first rotation pull mechanism group 64a and second rotation pull mechanism group
64b, first rotation pull the rotations of mechanism group 64a and second and pull mechanism group 64b with the third flanged plate 62 at respective place
The center line of plate face be symmetrical arranged, and the first rotation pulls the rotations of mechanism group 64a and second and pulls the rotation of mechanism group 64b and pulls
Mechanism 64 is uniformly distributed, and the position that the setting of mechanism 64 is pullled in rotation is very reasonable, and during second of flange, mechanism is pullled in rotation
Under 64 pullling, make 32 uniform force of the second outer side edges, the fold of inside region 2 is drawn to the center line of the second outer side edges 32
It pulls, achievees the purpose that remove fold.
The rotation pulls mechanism 64 and includes column spinner 641, third drive rod 643 and motor 644, and the motor 644 is solid
Surely it is arranged on the second cope plate 61, the motor 644 is by passing through the third drive rod 643 and column spinner of the second cope plate 61
641 are drivingly connected, and offer several installation positions 64 in the plate face of the third flanged plate 62, the column spinner 641 is vertically arranged
In installation position 64；Belong to the rotation side that the column spinner 641 of mechanism 64 is pullled in the rotation that mechanism group 64a is pullled in first rotation
The first spiral raised line 645 is provided with to the plate face center line towards third flanged plate 62, and on its cylinder；Belong to second rotation
Pull mechanism group 64b rotation pull mechanism 64 column spinner 641 direction of rotation also towards in the plate face of third flanged plate 62
Line, and the second spiral raised line 642 is provided with, the first spiral raised line 645 and the second spiral raised line 642 are revolved in column spinner 641
During turning there is certain torsion, the purpose for pullling de-shirred is taken into account while ensureing and reducing frictional resistance, and make whole
A second outer side edges, 32 uniform force；The hand of spiral of the first spiral raised line 645 and the second spiral raised line 642 is on the contrary, protect
It is as identical as possible to demonstrate,prove 32 center line both sides stress of the second outer side edges, and the face of the first spiral raised line 645 and the second spiral raised line 642
It is arcuate structure, prevents from scratching the second outer side edges 32 in rotary course, cause product unqualified.
A kind of processing method of liquid crystal display double flare frame, is as follows：
Step 1：Liquid crystal display frame 7, is put into annular cavity plate 54 by positioning first, the first drive shaft 43 connection pressure
Power machine drives the first upper die structure 4 to move down under forcing press effect, until 41 top edge of rectangular frame reaches outer side edges 3
First time flange folding line at, at this point, the lateral surface of rectangular frame 41 completes liquid against the medial surface of outer side edges 3
The positioning of crystal display frame 7；
Step 2：First time flange respectively starts the first driving means 531 of four the first flange bodies 53 simultaneously,
Under the driving of first driving means 531, the first flanged plate 533 moves and the arc-shaped corners of outer side edges 3 is pushed to turn down；
Step 3：First time flange respectively starts the second driving device 552 of four the second flange bodies 55 simultaneously,
Under the driving of the second driving device 552, the second flanged plate 551 moves and pushes remaining four straight line fold of outer side edges 3, complete
Into first time flange, liquid crystal display frame semi-finished product 8 are formed；
Step 4：Second of flange, the first upper die structure 4 exit, and the second drive shaft 63 of the second upper die structure 6 is connected
Forcing press drives the second upper die structure 6 to move down under forcing press effect, meanwhile, open motor 644, the driving rotation of motor 644
Rotary column 641 rotates, and the lower face of third flanged plate 62 contacts with the second outer side edges 32 and gradually pushes the second outer side edges 32 first,
During this, the first spiral raised line 645 and the second spiral raised line 642 under rotation status are by the second outer side edges 32 gradually to middle part
Position is pullled, and the fold of the inside region 2 of the second outer side edges 32 fades away under the effect of pullling, and completes second of flange, shape
Into liquid crystal display double flare frame 1.

(641) it is vertically arranged in installation position (64)；
Belong to the direction of rotation that the column spinner (641) of mechanism (64) is pullled in the rotation that mechanism group (64a) is pullled in first rotation
The first spiral raised line (645) is provided with towards the plate face center line of third flanged plate (62), and on its cylinder；Belong to second rotation
Turn pull mechanism group (64b) rotation pull mechanism (64) column spinner (641) direction of rotation also towards third flanged plate
(62) plate face center line, and it is provided with the second spiral raised line (642)；The first spiral raised line (645) and the second spiral
The hand of spiral of raised line (642) is on the contrary, and a face for the first spiral raised line (645) and the second spiral raised line (642) is arc
Structure.
7. a kind of processing method of liquid crystal display double flare frame, it is characterised in that：It is as follows：
Step 1：Liquid crystal display frame (7), is put into annular cavity plate (54) by positioning first, the first drive shaft (43) connection
Forcing press drives the first upper die structure (4) to move down under forcing press effect, outside rectangular frame (41) top edge reaches
At the folding line of the first time flange of side (3), at this point, inside of the lateral surface of rectangular frame (41) against outer side edges (3)
The positioning of liquid crystal display frame (7) is completed in face；
Step 2：First time flange respectively starts the first driving means (531) of four the first flange bodies (53) simultaneously,
Under first driving means (531) driving, the first flanged plate (533) is mobile and the arc-shaped corners of outer side edges (3) is pushed to turn down；
Step 3：First time flange respectively starts the second driving device (552) of four the second flange bodies (55) simultaneously,
Under the second driving device (552) driving, the second flanged plate (551) is mobile and pushes remaining four straight line of outer side edges (3)
First time flange is completed in fold, forms liquid crystal display frame semi-finished product (8)；Step 4：Second of flange, the first upper mold knot
Structure (4) exits, and the second drive shaft (63) of the second upper die structure (6) is connected forcing press, and second is driven under forcing press effect
Upper die structure (6) moves down, meanwhile, motor (644) is opened, motor (644) driving column spinner (641) rotates, third flange
The lower face of plate (62) contacts with the second outer side edges (32) and gradually pushes the second outer side edges (32) first, during this, rotation
The first spiral raised line (645) under state gradually draws the second outer side edges (32) with the second spiral raised line (642) to medium position
It pulls, the fold of the inside region (2) of the second outer side edges (32) fades away under the effect of pullling, and completes second of flange, is formed
Liquid crystal display double flare frame (1).
