Description
Technical field
The present invention relates to mould manufacturing field, more particularly to a kind of punching-pressing composite mould.
Background technology
At present, for the basic stamping procedure of the bool shaping of the two ends bending of holes at lateral wall is：It is blanking, punching, curved
In the middle of bent end, bending, specifically there is following four forming technology scheme：
（1）Blanking, rush areole, bending two ends, either simplex sequence shaping in the middle of bending；
（2）Blanking, rush areole and be first combined, then bend two ends, shaping in the middle of bending；
（3）Blanking, rush areole, bending two ends and be first combined, then bend middle shaping；
（4）Blanking, bending two ends, bending centre are first combined, then rush areole shaping.
By analysis, scheme（1）Mould structure is simple, but needs 4 secondary moulds, and efficiency is very low, and can not produce high accuracy
Stamping parts；Scheme（2）、（3）、（4）Structure is slightly more complex, and needs 2 pairs with mold, and accuracy and efficiency has largely
Improve.But these four schemes far can not meet modern production high accuracy, low cost, the requirement of high benefit.
The content of the invention

To on post；The lower mould also includes lower punch, lower lead column, side opening punch and wedge post, and lower punch is enclosed within lower lead column and tiltedly
On wedge post, side opening punch is embedded in lower punch.
Preferably, the upper mould also includes upper bolster, upper padding plate, convex die block, discharging rubber, stripper,
The upper padding plate, convex die block, discharging rubber and stripper are fixed on upper bolster lower plane after being sequentially overlapped；On described
Punch-die fixed plate is fixed with punch-die, and the upper plane of upper punch-die is against on upper padding plate, and upper punch-die is fixed with guiding
Post, upper punch-die are embedded with cut-out punch, and in upper lead column, the lower plane for cutting off punch is located at upper punch-die to cut-out punch case
In lower plane.
Preferably, the lower mould also includes that die shoe, lower bolster, kicker, the lower bolster and lower cavity die are folded successively
The plane on the die shoe is reinforced, lower punch and kicker in the middle of lower cavity die, is fixed with, lower punch and kicker are embedded in recessed
In the middle of mould, kicker is located between lower punch and lower cavity die, and the lower bolster of a fixed plate is fixed with lower lead column and wedge post,
Lower punch is embedded with side opening punch, and side opening punch guide section inclined-plane is fitted with the inclined-plane of wedge post.
The invention has the beneficial effects as follows：The present invention is a kind of punching-pressing composite mould, can make to cut tongue, bend middle, bending
Two ends, cut off, to rush areole, 6 operations of shaping once-combined, so only needs to 1 secondary mould, cut tongue, in the middle of bending, curved end
Portion, cut off, rush areole and completed before shaping successively, finally completing shaping, smoothly realize the compound of multiple operations, meet
Modern production high accuracy, low cost, the requirement of high benefit.
Description of the drawings
Fig. 1 is the structural representation of a preferred embodiment of punching-pressing composite mould of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings present pre-ferred embodiments are described in detail, so that the advantages and features of invention can be more easy to
In being readily appreciated by one skilled in the art, apparent clearly define so as to make to protection scope of the present invention.
Fig. 1 is referred to, the embodiment of the present invention includes：
A kind of punching-pressing composite mould, the composite die include upper die and lower die, are cased with mould on the guide pillar 17 of the lower mould
Guide pin bushing 16；It is described also to include in the middle of upper mould, being provided with lead column 13, convex die 7, upper punch-die 7 are cased with outside upper lead column 13
Cut-out punch 8 is embedded with, cut-out punch 8 is enclosed within lead column 13；It is described to be also provided with lower lead column 33, wedge post including lower mould
26th, with upper punch-die 7 and cut-out 8 corresponding lower cavity die 19 of punch, side opening punch 30, lower punch 34；The upper mould also includes upper
Die holder 5, upper padding plate 4, convex die block 3, discharging rubber 2, stripper 1, the upper padding plate 4, convex die block 3,
Discharging rubber 2 and stripper 1 are fixed on 5 lower plane of upper bolster after being sequentially overlapped；The convex die block 3 is fixed with convex
Die 7, the upper plane of upper punch-die 7 are against on upper padding plate 4, and the centre of upper punch-die 7 is fixed with lead column 13；The lower mould
Also include that die shoe 18, backing plate 25, lower bolster 28 and kicker 31, lower bolster 28 and lower cavity die 19 are sequentially overlapped and are fixed on lower mould
Plane on seat 18, backing plate 25, lower bolster 28, lower lead column 33 and wedge post 26 also are secured on die shoe 18 successively, lower cavity die 9
Centre is embedded with lower punch 34 and kicker 31, and kicker 31 is located between lower punch 34 and lower cavity die 19, and side opening punch 30 is embedded in
In lower punch 34, outside wedge post 28 and lower lead column 33, lower punch 34, the inclined-plane and wedge of the guide section of side opening punch 30 are cased with
The inclined-plane laminating of post 26.
The working method of punching-pressing composite mould of the present invention is：Do not indicate in the slide block figure of forcing press the upper mould of drive to
Lower motion, stripper 1 touch the processed blank being placed on lower cavity die 19 first, and discharging rubber 2 is compressed, and stripper 1 is pressed
Tight blank, cuts tongue and starts, and upper mould goes downwards to sweep incision, that is, cut tongue and complete；Upper mould is continued traveling downwardly, and starts to be flexed up to curved
Song is thick more than a material before terminating and bent intermediate radius sum, cuts off punch 8 also with cutting the carrying out of tongue and bending in push piece
Blank is compressed under the compression of spring 11, the following table until cutting off the upper surface of punch 8 to 7 centre position of upper punch-die
Face, before this equipment be supplied to the elastic force of lower punch 34 to be enough to overcome push piece spring 11 to be supplied to cut-out punch by screw 32
8 elastic force, lower punch 34 and cut-out punch 8 are in inactive state；Upper mould is continued traveling downwardly, and cut-out punch 8 is in upper punch-die 7
Equipment is overcome to be supplied to the elastic force of lower punch 34 under rigid pressure effect, under lower punch 34 is under the guide effect of lower lead column 33
Row completes cut-out, at the same time, is embedded in the lateral movement in the presence of wedge post inclined-plane of the side opening punch 30 in lower punch 34, directly
To the lower surface for completing to rush areole, lower punch 34 and kicker 33 while touching the upper surface of lower bolster 28, tongue, bending are cut
Centre, crooked end, cut off, rush areole, 6 operations of shaping and be fully completed.
Conversely, forcing press drives upper mould to move upwards during backhaul, lower punch 34 is also moved upwards, and side opening punch 30 is resetting
Reset in the presence of spring 27, the main discharging that blank is completed by stripper 1, side opening waste material is fallen from nib, by cutting
Side punch 8 and kicker 31 are respectively completed push piece and head part.
The present invention is a kind of punching-pressing composite mould, can make to cut tongue, in the middle of bending, bending two ends, cut off, rush areole,
6 operations of shaping are once-combined, so only need to 1 secondary mould, cut tongue, in the middle of bending, bending two ends, cut off, rush areole according to
It is secondary to complete before shaping, finally complete shaping, smoothly realize the compound of multiple operations, meet modern production high accuracy,
Low cost, the requirement of high benefit.
Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, it is every using this
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
