Detailed description of the invention
In order to solve the technical problem of double groove three-flange pipe end ends processing and forming difficulty, the utility model discloses
Double groove three-flange pipe end ends mould, by using the technological means of two times punch molding, it is possible at pipe end
The double groove three-flange of end machine-shaping, has filled up this technology blank at home, has had processing step simple, and production efficiency is high,
The advantage that Mold Making expense is low.
In order to clearly describe this utility model, new to this practicality with detailed description of the invention below in conjunction with the accompanying drawings
Type is described in further detail.
Embodiment
Double groove three-flange pipe end ends mould, including one-time-shaped mould and post forming mould, see Fig. 2 and
Fig. 6, respectively includes a clamping matched 2 and die shank 4, and clamping 2 is provided with clamp hole 21, is provided with along clamp hole 21 in die shank 4
Axial cylindric core rod 5, core rod 5 and metal tube 1 interference fit, be used for fixing metal tube 1 in clamp hole 21；In clamping 2
It is provided with two flange-types along clamp hole 21 axial arranging in the periphery, clamp hole 21 of core rod 5 with metal tube 1 interference areas
Chamber 6.Metal tube 1 is clamped in one end, clamp hole 21 by clamping 2, and core rod 5 penetrates in metal tube 1, with metal tube 1 interference fit, makes
Clamping 2 and the fixing connection of die shank 4, drift is entered clamp hole 21 by clamp hole 21 other end, the metal tube 1 that punching press is fixing, due to
Core rod 5 is positioned at metal tube 1, and metal tube 1 can only occur radial deformation to flange die cavity 6, forms flange 12, shape between flange 12
Become groove 11.
Wherein, seeing Fig. 3 and Fig. 7, the distance between two flange die cavities 6 of one-time-shaped mould is metal tube 1 three-flange
Distance between two end flange 12 of 12, the distance between two flange die cavities 6 of post forming mould is metal tube 1 three
Distance between end flange 12 and the spacer flanger 12 of flange 12.One-time-shaped mould and post forming mould flange die cavity 6
The setting of distance, it is therefore intended that first two end flange 12 in processing three-flange 12, reprocesses spacer flanger 12.
Concrete, the clamping 2 of one-time-shaped mould also includes slide block 3, sees Fig. 2-4, is positioned at the big with slide block 3 of this clamping 2
In the chute 23 of little and mating shapes, chute 23 is positioned at this clamping 2 end, and is positioned at the auxiliary section of clamping 2 and die shank 4, folder
Pore 21 runs through slide block 3, and slide block 3 axially can slide along clamp hole 21 in chute 23, two flange-types of one-time-shaped mould
Chamber 6 lays respectively at the both ends of slide block 3, slide block 3 surround with bottom die shank 4 end, chute 23 respectively.
Fig. 2 is shown in by the assembling schematic diagram of metal tube 1 to be processed and one-time-shaped mould, and the clamping 2 of one-time-shaped mould is passed through
Slide block 3 and the setting of chute 23 so that metal tube 1 is when punching press, and two flange die cavity 6 all leaves the deformation space of abundance,
Metal tube 1 is made axially to press short, it is ensured that metal tube 1 radially deformation is abundant, forms good, regular flange 12 outward appearance.Half prepared
Fig. 5 is shown in by finished metal pipe 1, first processes two end flange 12 in three-flange 12.
Concrete, see Fig. 6 and Fig. 9, die shank 4 end of post forming mould is provided with flange die cavity 6, by die shank 4 end and
The clamping 2 of post forming mould surrounds.
Semi-finished metal pipe 1 is clamped by the clamping 2 of post forming mould in the one end in clamp hole 21, and becomes with secondary
Core rod 5 in the die shank 4 of mould is connected with semi-finished metal pipe 1 interference fit, makes semi-finished metal pipe 1 be fixed on secondary
In the clamping 2 of mould and die shank 4, the connector of clamping 2 and die shank 4 constitutes three flange die cavities 6, two processed altogether
Individual end flange 12 lays respectively at the flange die cavity 6 on both sides in three flange die cavities 6, and these two flange die cavities 6 are to one-shot forming
Two flanges 12 that processing prepares play a protective role, and prevent post-forming process from it is caused damage.Middle flange die cavity 6
For post-forming process.
See Fig. 8 and Fig. 9, the semi-finished metal pipe 1 punch forming in post forming mould.
As the presently preferred embodiments, clamping 2 is provided with the guide pillar hole 22 keeping vertical with clamp hole 21, and guide pillar penetrates guide pillar hole
22.Drift high speed impact in clamp hole 21 during punching press, if clamp hole 21 not level, causes damage to drift, simultaneously clamp
In hole 21, product body can damage.Guide pillar ensure that clamp hole 21 level, it is to avoid because clamping is the most just causing drift impaired, produces
QC bulk damage.
Above this utility model is described in detail, this utility model is applied specific case to of the present utility model
Embodiment is set forth, and the explanation of above example is only intended to help and understands this utility model, it is noted that for this
For those skilled in the art, on the premise of without departing from this utility model principle, if also this utility model can be carried out
Dry improvement, these improvement also fall in this utility model scope of the claims.
