Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
The embodiments of the present invention：As in Figure 2-4, a kind of flanging die, including upper die component and lower mold assemblies, institute
It includes upper die holder 11, upper mold material pressing core 12 and flanging die 13 to state upper die component, the upper mold material pressing core 12 by spring 16 with
The upper die holder 11 connects, and the flanging die 13 is removably mounted on the upper die holder 11.As shown in figure 5, described turn over
Side punch-pin 13 includes middle part flanging die 131 and both sides flanging die 132, and the middle part flanging die 131 is to the lower module
The direction of part extends, and the both sides flanging die 132 extends to both sides.The lower mold assemblies include lower die holder 21, cavity plate frame 22
And lower die material pressing core 23, the cavity plate frame 22 are mounted on the lower die holder 21, the lower die material pressing core 23 is set to the cavity plate
In frame 22.Specifically, the lower die material pressing core 23 may be mounted on the lower die holder 21, can also be mounted on the cavity plate frame
On 22.
When in use, as shown in figure 4, first the plate (not shown) after blanking is placed on cavity plate frame 22, then
Lathe (not shown) is jacked up lower die material pressing core 23 by mandril 25, until lower die material pressing core 23 is contacted with plate；Then
Upper die component downlink, upper mold material pressing core 12 is contacted with plate, and plate is compressed；Upper die component continues traveling downwardly, flanging die 13
Middle part flanging die 131 and cavity plate frame 22 and lower die material pressing core 23 coordinate, plate is carried out to lower flange, middle part flanging die
131 complete to lower flange, at this point, forming the first flange 01 in Fig. 1；But due to being connected using spring 16, upper mold material pressing core
12 meeting compressed springs 16 can not carry out flange to plate, until spring 16 is compressed to minimum point, then upper die component continues
The both sides flanging die 132 of downlink, upper mold material pressing core 12 and flanging die 13 collectively as flanging die, with cavity plate frame 22 and under
Molding compound core 23 coordinates, and carries out plate to upper overturning, can be obtained workpiece as shown in Figure 1 after the completion to upper overturning.This reality
The flanging die for applying example offer, is optimized, and coordinate its structure design cavity plate frame by the structure to flanging die 13
22 and lower die material pressing core 23, using the one set of die, by one of overturning process, you can process originally using two molds,
By the getable workpiece of the ability of overturning process twice, mould development cost is not only effectively reduced, also substantially increases production effect
Rate.
Specifically, first the upper mold material pressing core 12 and the flanging die 13 can be mounted on upper die plate 14, institute
Upper die plate 14 is stated to be fixed on the upper die holder 11 by bolt 15 again.By be arranged upper die plate 14, can in punching press,
Certain cushioning effect is played, prevents flanging die 13 from being squeezed even damage upper die holder by the reaction force of lower die material pressing core 23
11；Mold height can also be increased, be convenient for the adjustment of mold.It is of course also possible to upper die plate 14 is omitted, but correspondingly upper mold
The size of material pressing core 12 and flanging die 13, which need to be made, correspondingly to be changed, and upper mold material pressing core 12 can be by spring 16 directly and upper die holder
11 connections, flanging die 13 can be directly anchored on upper die holder 11.
Wherein, for the ease of demoulding and extending the service life of mold, enable the upper mold material pressing core 12 and the flange convex
Mould 13 all has pattern draft.
In a kind of specifically embodiment, the flanging die 13 further includes punch-pin matrix 133, the punch-pin matrix
133 connect with the both sides flanging die 132, and around the upper mold material pressing core 12.Punch-pin matrix 133 be used for it is recessed
Framed 22 cooperation, can be equivalent to blank holder；And due to 132 small volume of both sides flanging die, be not easy to fix, setting and its
The punch-pin matrix 133 of connection, can be in order to the fixation of both sides flanging die 132；It can certainly be not provided with punch-pin matrix 133,
But the size of upper mold material pressing core 12 need to be changed, that is, it is integrated on upper mold material pressing core 12.
It being preferably carried out in mode in one kind, the upper mold material pressing core 12 is split structure, including link together
Matrix and molding plane.Since upper mold material pressing core 12 will also be used as flanging die, thickness is relatively large, split type knot
Structure, the processing and repair of upper mold of being more convenient for material pressing core 12.Similarly, it if the thickness of lower die material pressing core 23 is also larger, can also design
At separate structure.
It is preferably carried out in mode in one kind, cavity plate is also embedded between the cavity plate frame 22 and the lower die material pressing core 23
Insert 24, and the die plate insert 24 is higher than the lower die material pressing core 23, i.e. die plate insert 24 and lower die material pressing core 23 forms one
A whole cavity die structure, the flanging die for being collectively constituted with upper mold material pressing core 12 and both sides flanging die 132 match, single
Solely design die plate insert 24 can realize the replacement of mold when workpiece local size is changed by replacing die plate insert 24, without
With whole set of die is replaced, enhances the versatility of the flanging die, improve the efficiency of more mold exchange.
It should be noted that the present embodiment is described with workpiece shown in Fig. 1, but the utility model carries
The flanging die of confession is applicable not only to the workpiece, it can also be used to other similar workpiece (such as the equal flange in both ends, it is whole be L-shaped or
Other shapes etc.) molding.
The structure, feature and effect of the utility model are described in detail based on the embodiments shown in the drawings, with
Upper described is only the preferred embodiment of the utility model, but the utility model is to limit practical range shown in drawing, it is every according to
Change made by conception according to the utility model, or be revised as the equivalent embodiment of equivalent variations, still without departing from specification and figure
When showing covered spirit, it should be within the protection scope of the present utility model.
