Description
Technical field
The present invention relates to Stamping Die Technology field, especially a kind of punched pipefitting necking die.
Background technology
The plastic working of pipe fitting is to make tubing under external force, produces plastic deformation, shape, size, group needed for acquisition
A kind of basic intermetallic composite coating skill with the product of performance is knitted, it mainly includes bending, bulging, enlarging, necking, flange etc..Its
In, necking is a kind of moulding process that its oral area is reduced to pipe fitting by necking die.A kind of existing punched pipefitting necking
Mould includes the lower mold assemblies for being provided with necking die cavity, the upper die component of clamping pipe fitting upper end, when carrying out necking operation, by pipe fitting
Upper end is fixedly clamped on upper die component, erects pipe fitting, and forcing press driving upper die component moves downward, the lower end insertion of pipe fitting
In the necking die cavity of lower mold assemblies, under pressure, the lower end of pipe fitting produces plastic deformation under the limitation of shrinkage cavity die cavity, real
Existing necking.The necking die of this structure has the following disadvantages：Pipe fitting category thin-wall part, if axial compression is big, it can easily make biography
Power area axial direction unstability, cause tube wall fold or pipe fitting flexural deformation；Pipe fitting clamping is complicated.
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
Tool exist pipe fitting be easily deformed with pipe fitting clamping it is complicated the problem of.
In order to solve the above problems, the technical solution adopted by the present invention is：This punched pipefitting necking die includes upper mould
Plate and die shoe, the die shoe are fixed with support block, and the upper surface of the support block is offered for laterally disposed pipe fitting
Low groove；The die shoe is connected with slipping matrix, and the slipping matrix is slidably matched with the die shoe, the slipping matrix
One end of the support block is provided with necking die cavity, the other end is by the first spring with being fixed on consolidating on the die shoe
Fixed board；The cope plate is provided with voussoir, the opposite face of the voussoir and the slipping matrix be respectively be slidably matched it is upper tiltedly
Face, lower inclined plane, the lower inclined plane is tiltedly back to the support block；The cope plate is connected with briquetting, the pressure by second spring
The lower surface of block offers the upper groove relative with the low groove.
In the technical scheme of above-mentioned punched pipefitting necking die, more specifically technical scheme can also be：In the lower mould
Guide groove is provided with seat between the fixed plate and support block, the slipping matrix bottom has the cunning inserted in the guide groove
Block.
Further, regulation limiting plate, the regulation limiting plate are connected with by the support block on the die shoe
Elongated hole is offered, bolt is provided with the elongated hole, the regulation limiting plate is connected by bolt with the die shoe.
Further, one end of the slipping matrix is provided with locating piece in the support block.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, set the support block with low groove to carry out horizontal positioned pipe fitting, coordinated by the inclined-plane of voussoir and slipping matrix, make voussoir
Lower pressure be converted into slipping matrix to the driving force of pipe fitting transverse shifting, realize necking, cope plate is connected by second spring
Briquetting can coordinate with support block compresses pipe fitting, reduces the possibility deformed during pipe fitting necking, and clamping structure is simple, easily
In manufacture.
The 2nd, guide groove and sliding block and locating piece are set, the accuracy of necking can be improved.
The 3rd, regulation limiting plate is set, be avoided that pipe fitting moves during necking.
Brief description of the drawings
Fig. 1 is the structural representation of this punched pipefitting necking die.
Fig. 2 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 die shoe 1, fixed plate 2, the first spring 3, slipping matrix
4th, voussoir 5, cope plate 6, second spring 7, briquetting 8, support block 9 and regulation limiting plate 10.On die shoe 1 along its length according to
Secondary to be provided with fixed plate 2, slipping matrix 4, support block 9 and regulation limiting plate 10, fixed plate 1 and support block 9 are fixed on die shoe 1
On, slipping matrix 4 is slidably matched with die shoe 1, and regulation limiting plate 10 is connected by bolt and die shoe 1.Slipping matrix 4
One end be connected by the first spring 3 with fixed plate 1, the other end is provided with necking die cavity 4-2, necking die cavity 4-2 towards support
The side of block 9 is set, and is provided with the low groove 9-1 for laterally disposed pipe fitting 12 in support block 9, necking die cavity 4-2 with
The pipe fitting 12 being placed in the low groove 9-1 of support block 9 is coaxial.The upper end for adjusting limiting plate 10 is higher than low groove 9-1 bottom, with
It is easy to the other end with pipe fitting 12 to abut against, so as to avoid pipe fitting 10 from producing movement under the promotion of slipping matrix 4；Adjust spacing
The bottom of plate 10 offers elongated hole, and bolt is provided with elongated hole, and regulation limiting plate 10 is connected by bolt with die shoe 1.Under
Guide groove 1-1 is offered on die holder 1 between fixed plate 2 and support block 9, sliding recessed 4 mould bottom has the cunning inserted in guide groove 1-1
Block 4-3.Cope plate 6 is fixed with voussoir 5, and wedge, 5 are provided with ramp 5-1, and slipping matrix 4, which is provided with to slide with ramp 5-1, matches somebody with somebody
The lower inclined plane 4-1 of conjunction, lower inclined plane 4-1 are tiltedly set back to support block 9；Cope plate 6 is connected with briquetting 8 by second spring 7, is pressing
