Mould 1 and lower mould 2 is accurately positioned in block, realization.
As viewed in figures 5-8, the specific forming process of the present embodiment is as described below：
Upper mould 1 and lower mould 2 are individually fixed in the upper table surface and following table of forcing press first, upper mould is driven by forcing press
1 and lower mould 2 is relative moves up and down；Sheet metal is placed horizontally on stripper plate 22, by alignment sensor 31 by metal foil
The location information of plate is transmitted to controller；Worked by controller drive cylinder component 7, the driving pushing block 8 of cylinder assembly 7 promotes the
Two punch-pin 132 are moved downward so that the bottom surface of the second punch-pin 132 is concordant with the bottom surface of the first punch-pin 131；
Then upper mould 1 is driven descending by forcing press, and inserted block 9 is contacted with sliding block 29, and drives sliding block 29 to be moved to the left,
So that the second flange cutter block 28 and sheet metal contact aside, the first punch-pin 131 and the second punch-pin 132 in the presence of forcing press
Inconsistent with sheet metal, sheet metal is pressed into arc, and now the first nitrogen spring 15 and the second nitrogen spring 24 are in just
Beginning state；Stripper plate 22 continues to be pushed by punch assemblies 13 under the drive of forcing press, and sheet metal is in punch assemblies 13, first
Into U-shaped under the mating reaction of the flange cutter block 28 of flange cutter block 27 and second, now stripper plate 22 is by the first of the first nitrogen spring 15
Beginning power F is forced into bottom, and the second nitrogen spring 24 is accordingly by one stroke L1 of compression；Under upper mould 1 continues under the drive of forcing press
A stroke S is moved, sliding block 29 is moved farther leftward as in the presence of inserted block 9, work of the sheet metal in the second flange cutter block 28
Bent inwards with lower one side, the sheet metal shaped；Now punch assemblies are accordingly compressed, the corresponding quilt of the first nitrogen spring
Compress a stroke S；
During the demoulding, upper mould 1 goes upward to inserted block 9 under the drive of forcing press and is kept completely separate with sliding block 29, and sliding block 29 is first
Initial position is returned in the presence of spring 5；The sheet metal of shaping is up with punch assemblies 13, passes through controller drive cylinder group
The return of part 7, pushing block 8 is retracted under the drive of cylinder assembly 7 between the first punch-pin 131 and the second punch-pin 132；Now second is convex
Mould 132 is replied upwards in the presence of second spring 6 so that the sheet metal of shaping departs from from the second punch-pin 132, and the
One nitrogen spring 15 and the second nitrogen spring 24 accordingly recover to original state；
Wherein, the starting force F of first nitrogen spring 15 is more than the compression stress of the second nitrogen spring 24, wherein S, L
It is all higher than 0.The power that second nitrogen spring 24 is compressed to end-state is more than by the starting force of the first nitrogen spring 15, i.e.,, it is ensured that when carrying out step S5, processed sheet metal will not be shifted over or deform.
In summary, a kind of composite pressure shaped device and its shaping side for bloom sheet metal that the present invention is provided
Method, it is simple in construction, the unstable caused waste of inter process positioning is greatly decreased, production efficiency and yield rate is improved.
The object, technical solutions and advantages of the present invention are further described by above-listed preferred embodiment, are answered
Understand, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
