It sets and is sequentially connected with metal plate moulding mould.
As shown in Figures 1 to 4, specific embodiment of the present invention provides a kind of metal plate moulding mould, which is
For manuscript 8 to sheet metal component 9 shown in Fig. 10,9 structure of sheet metal component before punching press is referring to Fig. 5 to Fig. 7.As shown in figure 8, metal plate
Golden 9 surrounding of part carries out bending by the sequence of A, B, C, to four side carry out sequence bendings, to reach the molding character requirement of part.Such as
Shown in Fig. 1 and Fig. 2, a kind of surrounding bend forming die includes upper die and lower die, when the slide block down of stamping equipment, upper mold and
Lower die cooperation is treated bending sheet metal component 9 and is clamped.When upper mold stress moves downward, the bending structure of upper die and lower die is treated
The 9 carry out sequence bending of sheet metal component of bending.
Upper mold includes upper die holder 1, upper clamp plate 2, cope plate 3 and preloading block 12.Upper die holder 1, upper clamp plate 2 and cope plate 3 are certainly
It is fixedly connected sequentially under above, preloading block 12 is fixed on the bottom side of upper die holder 1.
Lower die include lower die holder 7, lower bolster 6, lower de- plate 4, as folded block 25,38 and of folded block of fixed folded block
Folded block 4 10 and the first spring 11, second spring 13 and (bending number of blocks etc. of folded block 1 as movable folded block
In practical bending edges quantity).Folded block 25, folded block 38, folded block 4 10 are connect with lower bolster 6, lower bolster 6 and lower die holder
7 are fixedly connected, and lower de- plate 4 is connect by the first spring 11 with lower die holder 7, and folded block is connected by second spring 13 and lower die holder 7
It connecing, the first spring 11 can provide driving force for lower de- plate 4, and second spring 13 can provide driving force for folded block 1, thus
Sheet metal component 9 is clamped, bending, de- material.
9 unique characteristics of sheet metal component limitation, so that one 14 height of folded block is lower than folded block 25 and folded block 38, by the
High folded block 1 is floated in the effect of two springs 13, and under die opening state, the upper surface of folded block 1 is higher than folded block 25, folding
The upper surface of curved piece 38 and folded block 4 10, therefore sheet metal component 9 first rolls over front side edge.On 25 upper surface of folded block and folded block 38
The height on surface is identical, ensure that left and right sides bending simultaneously；4 10 upper surface of folded block is lower than folded block 25 and folded block three
8 upper surface, the rear side that ensure that last folding sheet metal component 9.
Specific work process are as follows:
(1) it is placed on lower de- plate 4 and folded block 1 to the sheet metal component of bending 9, stamping equipment slide block down, in pushing
Die holder 1, moves downward part of the upper die, until cope plate 3 is contacted with sheet metal component 9, bending starts；
(2) stamping equipment sliding block continues traveling downwardly, and lower de- plate 4 and cope plate 3 move downward, the upper surface of lower de- plate 4 by
The progressively lower upper surface in folded block 1, starts bending and molding on front side of sheet metal component 9, after 9 front side bending and forming of sheet metal component, the second bullet
Spring 13 will not continue movement downwards until prefabricating plate is acted on bending plate one and just moved downward；
(3) stamping equipment sliding block continues traveling downwardly, and lower de- plate 4 and cope plate 3 continue to move downward, the upper surface of lower de- plate 4
Gradually it is lower than the upper surface of folded block 25 and folded block 38,9 left side of sheet metal component and right side start simultaneously at bending and forming；
(4) stamping equipment sliding block continues traveling downwardly, and lower de- plate 4 and cope plate 3 continue to move downward, lower de- 4 upper surface of plate by
The progressively lower upper surface in folded block starts bending and forming on rear side of sheet metal component 9；
(5) stamping equipment sliding block continues traveling downwardly, and lower de- plate 4 and cope plate 3 continue to move downward, 12 lower surface of preloading block with
The contact of one 14 upper surface of folded block, folded block 1 starts to move downward under the action of preloading block 12, when coming downwards to bottom dead centre
When sheet metal component 9 complete flexing movement, folded block 1 is in and does not kill state, and lower de- plate 4 and cope plate 3 are in and kill shape
State, at this point, lower de- plate 4, cope plate 3, the position of preloading block 12 and folded block 1 are as shown in Figure 4；
(6) stamping equipment sliding block uplink, lower de- plate 4 reset upwards under the action of the first spring 11, and folded block 1 exists
It is resetted upwards under the action of second spring 13, folded block 1, folded block 25, folded block 38, folded block 4 10 and sheet metal component 9
It is detached from；
(7) stamping equipment sliding block continues uplink, and under the effect of upper mold material-removing structure, cope plate 3 starts de- with sheet metal component 9
From sliding block goes upward to top dead-centre, completes stripping action.
It is not limited to two springs in practical applications, enough pressure-plate-forces and pressure plate can be provided by multiple springs
Balance.The effect of first spring 11 provides pressure-plate-force and stripping force to sheet metal part, 13 offer activity of second spring folding when being bending
The curved power of curved piece of reflexed.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be wanted with right
Subject to the protection scope asked.
