Description
Technical field
The present invention relates to pipe fitting processing technique field more particularly to a kind of pipe side cinclides reaming-forming devices.
Background technique
There are also the connecting bypass branch pipes on main pipeline other than being directly integrally formed for the mode of production tee tube, four-way pipe etc.
Mode, traditional processing method is that an aperture is opened up on main pipeline, and a taper is then placed into inside main pipeline
Reamer, the small end face aperture of reamer, then by the small end of reamer be located at aperture outside force application mechanism connect,
Force application mechanism by reamer from aperture pull out, thus reamer by pore expansion theory at the flanging bore routed up outward, then to flange
Hole modify and then connecting bypass branch pipe is finally made tee tube, four-way pipe etc. on flanging bore again.
Existing processing method needs to be placed into the reamer of taper is point-device in supervisor, needs reamer
The accurate alignment apertures of small end, placement operation difficulty is big, inefficiency, during reamer is pulled out reaming from aperture,
The axial direction of reamer is easy to appear the situation of skew, and the low precision of the flanging bore processed, centering is poor, be easy to cause flanging bore
Wall unevenness, different in size, the peripheral distortion for the flanging bore that reaming-forming processes is serious, and processing quality difference is difficult to meet need
It asks.
Summary of the invention
The technical problems to be solved by the invention and the technical assignment of proposition are improved to the prior art, and one kind is provided
Pipe side cinclides reaming-forming device solves to carry out reaming using areole of the reamer of taper to main pipeline in current technology
The problem of molding, difficulty of processing is big, low efficiency, low precision.
In order to solve the above technical problems, the technical scheme is that
A kind of pipe side cinclides reaming-forming device, the reaming die body including the first formed punch, the second formed punch and spherical shape are described
The first formed punch, the second formed punch be inserted into respectively from the both ends of main pipeline, and in first formed punch, second formed punch the two extremely
The inclined inclined surface in main pipeline axial direction in front end in the insertion main pipeline of few one, reaming die body be placed in main pipeline it is interior and
Between the first formed punch, the second formed punch, the first formed punch, the second formed punch are close in main pipeline and push reaming die body to supervisor
The areole opened up on road side wall is mobile, and reaming die body carries out reaming-forming processing to areole.Pipe side of the present invention
Cinclides reaming-forming device carries out reaming-forming using spherical reaming die body, and spherical reaming die body itself does not have directionality,
Its any position can be adopted to carry out reaming-forming to areole, and the reaming-forming effect of any direction is consistent, only
Spherical reaming die body need to be put into main pipeline, also be needed when eliminating using traditional tapered reamer by countersinking
The small end of device precisely aligns the operation of aperture, processes the first punching that is more convenient simple, high-efficient, and passing through insertion main pipeline
Head, the second formed punch front end contact of incline plane reaming die body and push spherical reaming die body, make reaming die body along main pipeline diameter
Reach reaming-forming to towards mobile squeeze areole formation of areole, and since reaming die body is spherical in shape, any
Reaming die body is all uniform to the dilating effect power of areole on direction, so that it is whole at its to ensure that reaming-forming obtains flanging bore
All be in a circumferential direction it is uniform, improve reaming-forming precision and quality, the first formed punch, the second formed punch by reaming die body from reaming at
Type obtains flanging bore and squeezes out main pipeline, and then the first formed punch, the second formed punch exit main pipeline, to main pipeline areole reaming-forming
