Abstract
The invention discloses a kind of punched pipefitting necking die, it is related to Stamping Die Technology field, two including being fixed on the die shoe lower cavity dies that are oppositely arranged, support block is provided between two lower cavity dies, the support block is by multiple spring supportings above the die shoe, and the upper surface of the support block offers the stopper slot for horizontal positioned pipe fitting；The upper cavity die corresponding with two lower cavity dies is fixed with cope plate, the upper cavity die and the lower cavity die enclose to form necking die cavity.The present invention, which solves existing pipe fitting necking die and existed, to be easily deformed to long pipe fitting necking and the problem of impulse stroke is larger.
Description
Technical field
The present invention relates to Stamping Die Technology field, especially a kind of punched pipefitting necking die.
Background technology
Pipe fitting necking is the moulding process for reducing blank end diameter, and conventional pipe fitting necking is carried out using upper reducing die
Necking, pipe fitting lower end is fixed on press bench, and pipe fitting is placed in upright state, and forcing press drives upper reducing die
Decline, after pipe fitting is contacted with upper institute's mouth mold, under powerful pressure effect, the upper end of pipe fitting is squeezed into the necking of reducing die
In die cavity, necking is realized, but it once can only carry out necking to one end of pipe fitting, and necking is less efficient.A kind of existing two ends
The diel of necking includes upper mould, chuck and lower mould, and upper die and lower die are respectively arranged with relative necking die cavity, and chuck is placed
It is used for auxiliary pipe fitting on lower mould and erects setting, the lower end of pipe fitting is abutted against with the conical surface top of drag chamber, and forcing press is pushed
Afterwards, the upper and lower side of pipe fitting is squeezed into the necking die cavity of upper die and lower die respectively, realizes two ends necking.Above-mentioned necking die exist with
Lower deficiency：Necking is carried out to longer pipe fitting, flexural deformation is easily produced under pressure；During discharging, to meet pipe fitting and
There are enough pickup distances between upper mould, it is desirable to have larger impulse stroke.
The content of the invention
It is an object of the invention to provide a kind of punched pipefitting necking die, this mould can solve existing pipe fitting reducing die
The problem of tool presence is easily deformed to longer pipe fitting necking and impulse stroke is larger.
In order to solve the above problems, the technical solution adopted by the present invention is：This punched pipefitting necking die includes fixing
Two on the die shoe lower cavity dies that are oppositely arranged, are provided with support block, the support block between two lower cavity dies
By multiple spring supportings above the die shoe, the upper surface of the support block offers the limit for horizontal positioned pipe fitting
Position groove, the stopper slot is set towards the lower cavity die；The fovea superior corresponding with two lower cavity dies is fixed with cope plate
Mould, the upper cavity die and the lower cavity die enclose to form necking die cavity.
In the technical scheme of above-mentioned punched pipefitting necking die, more specifically technical scheme can also be：The support block
Two side ends coordinate with the recessed die clearance.
Further, the upper surface of the support block is provided with the chuck for clamping the pipe fitting, and the chuck includes
Upper chuck and the first connecting seat and the second connecting seat for being fixed on the support block, first connecting seat and described second connect
Joint chair is symmetricly set in the stopper slot both sides；One end of the upper chuck is hinged with first connecting seat, the upper chuck
The other end be connected by pin with second connecting seat.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, set and surround the upper cavity die and lower cavity die to form necking die cavity, and the support of support tubes is set between two re-entrant molds
Block, support block bottom sets spring, and the part of pipe fitting not necking is placed by support block support level, and stamping press is concentrated by cavity plate
Necking part is acted on, is not easy to be deformed during stamping necking even if pipe fitting is longer；Pipe fitting horizontal positioned, significantly
Degree shortens the impulse stroke of punching press.
2nd, support block and recessed die clearance coordinate, both increased pipe fitting by bearing length, further reduction deformation can
Can, in turn ensure that support block can be moved up and down smoothly.
The 3rd, chuck is set in support block, for clamping pipe fitting, it is to avoid firmware produces displacement in punching course.
Brief description of the drawings
Fig. 1 is the structural representation of this punched pipefitting necking die.
Fig. 2 is Fig. 1 right view.
Fig. 3 is necking view.
Embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Punched pipefitting necking die shown in Fig. 1 and Fig. 2 mainly includes cope plate 1, upper cavity die 2, lower cavity die 3, die shoe 4, branch
Bracer 5, spring 6 and chuck 7, are fixed with two lower cavity dies being oppositely arranged 3 on die shoe 4, are fixed with and two in cope plate 1
Two corresponding upper cavity dies 2 of individual lower cavity die 3, corresponding upper cavity die 2 and lower cavity die 3 enclose to form necking die cavity；Under two
Be provided with the support block 5 that multiple springs 6 are supported in the top of die shoe 4 between cavity plate 3, the two side ends of support block 5 respectively with
The gap of lower cavity die 3 coordinates, and the upper surface of support block 5 offers spacing, the 5-1 for horizontal positioned pipe fitting 8, spacing referring to Fig. 3
Groove 5-1 two ends are respectively facing lower cavity die 3 and set, and stopper slot 5-1 cross-sectional profiles are the minor arc matched with pipe fitting 8；Bullet
Spring 6 under normal conditions when, the stopper slot 5-1 of support block 5 bottom line be slightly above the surface of lower cavity die 3 or with the flush of lower cavity die 3；Branch
The upper surface of bracer 5 is provided with the chuck 7 for clamping pipe fitting 8, and chuck 7 includes upper chuck 7-3 and is fixed on support block 5
First connecting seat 7-1 and the second connecting seat 7-2, the first connecting seat 7-1 and the second connecting seat 7-2 are symmetricly set in stopper slot 5-1
Both sides；Upper chuck 7-3 one end is hinged with the first connecting seat 7-1, and the upper chuck 7-3 other end is connected by pin 7-4 and second
Joint chair 7-2 connections.
In use, pipe fitting 8 is placed in the stopper slot 5-1 of support block 5, and the two ends of pipe fitting 8 are made to be symmetricly set on two
Between the individual outer end border of lower cavity die 3, upper chuck 7-3 is closed up with the second connecting seat 7-2, plugging pin 7-4 locks chuck 7
Afterwards, Opening pressure machine, cope plate 1 drives upper cavity die 2 to move down, after the mold cavity surface of upper cavity die 2 is contacted with pipe fitting 8, makees in pressure
Under, the two ends of pipe fitting 8 carry out necking simultaneously；After the completion of necking, die sinking removes pin 7-4, upper chuck 7-3 is opened, and takes out
Pipe fitting 8.
