Description
Technical field
The utility model relates to a kind of metal tube pipe end processing technique field, relates in particular to a kind of metal tube pipe end mouthful mould that rises.
Background technology
The metal tube pipe end mouthful technology that rises is that pipe fitting termination that diameter is little is expanded and is the processing technology of larger-diameter pipe fitting termination.The enlarging mould that uses in the existing technology, as application number is 200820123506.1, and the Chinese utility model patent that name is called " mould of enlarged metal nozzle diameter " utilizes moving sliding sleeve and core, make that pipe fitting is kept away resistance outward and reduced when the local expansion of the metal mouth of pipe.And for example, application number is: 200710022135.8, and name is called: the Chinese invention patent of " a kind of pipe-expansion mold " by the cone match of the bellmouth support among the mandrel and the body that rises, makes the axial thrust that is added on the mandrel be converted into expansionary force.Yet still there is following shortcoming in existing pipe fitting enlarging mould: the deformation coefficient of the ratio of the caliber D after caliber d before the distortion and the distortion is too small, it is improper that pressing direction is selected, mould is installed improper, the press machine tool precision is not high enough, cause that pipe fitting port gap is inhomogeneous, cause rise port area fracture of pipe end easily.
The utility model content
The purpose of this utility model provides a kind of metal tube pipe end mouthful mould that rises, and can make pipe fitting port gap even, and the port area that rises of pipe end is not easy fracture to occur, and the yield rate height helps enhancing productivity.
In order to realize above-mentioned purpose of design, the scheme that the utility model adopts is as follows:
A kind of metal tube pipe end mouthful mould that rises, comprise positioning pedestal 1, following positioning pedestal 2, punch 3, punch fixed axis 4, upper cavity die 5, lower cavity die 6, wherein said upper cavity die 5 is connected to described going up in the positioning pedestal 1, to realize its location, described lower cavity die 6 is connected to down in the positioning pedestal 2, to realize its location, described punch 3 connects the location by punch fixed axis 4.
Preferably, the described last end face of going up positioning pedestal 1 is provided with four screws 8, and is fixed on the lathe by screw 8, and the described bottom surface of positioning pedestal 2 down is provided with positioning key 7, and by positioning key 7 centerings.
Preferably, described punch fixed axis 4 is fixed on the lathe, and mould is installed by key, and described upper cavity die 5, lower cavity die 6 align mutually by pilot pin.
Preferably, the material selection Q235 of upper cavity die and lower cavity die, punch, up and down the cutting edge of die material all select 45 for use, modified HRC40-45.
The beneficial effects of the utility model are: a kind of metal tube pipe end of the present utility model mouthful mould that rises, by positioning pedestal up and down, last lower cavity die, punch, the structure of punch locating shaft, the lathe side has jackscrew to compress, the employing side pressure is shaped, it is suitable to make mould install, deft design, can make pipe fitting port gap even, the port area that rises of pipe end is not easy fracture to occur, and the yield rate height helps enhancing productivity, reduce production costs, the upper and lower mould structure Design can satisfy the production that the difform pipe end of different length and pipe fitting rear portion rises mouthful, and is applied widely, is easy to promote the use of.
