Footpath carries out finishing, the machinery of calibration.
Background technology
At present, the Material Strength on the oil-gas pipeline particularly at the line up butt welding such as elbow, threeway, tube type requirements compared with
Height, often the part of straight forming do not reach requirement.Internal, external diameter is needed to carry out the material that finishing, calibration change the mouth of pipe simultaneously
Intensity.
In prior art, generally the intensity requirement of material is met using the method for bulk heat treatmet, is expired with machining
Foot is inside and outside, the dimensional requirement in footpath, its troublesome poeration, high cost, inefficiency.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, there is provided a kind of interior expansion of cast part rational in infrastructure
The machinery of external contracting, is carried out, easy to operate, work efficiency simultaneously such that it is able to expand the port Inner of cast part with external contracting
It is high.
The technical scheme that this utility model is adopted is as follows：
A kind of cast part with it is interior expansion external contracting machinery, including it is interior expand part and external contracting part, the interior expansion part
Structure be：Including pull bar, cone is installed on the outer circumference surface of the pull bar, first is passed through on the outer circumference surface of the cone
The T-shaped key of length installs the first die holder, and one end of first die holder is connected by securing member with inner mold, first die holder it is another
One end is provided with gripper shoe, is connected with the first die holder by the first short T-shaped key in the gripper shoe；The structure of the external contracting part
For：Including inverted cone pedestal, connecting rod is separately installed with described four angles of inverted cone pedestal end face, by the in the inverted cone pedestal
The two T-shaped keys of length are provided with the second die holder, one end of second die holder by securing member installation outer mold, the outer mold with it is interior
Mould spacing distance, the other end of second die holder is connected in gripper shoe by the second short T-shaped being bonded.
As the further improvement of above-mentioned technical proposal：
Wall thickness of the spacing distance between the outer mold and inner mold more than workpiece.
The beneficial effects of the utility model are as follows：
This utility model compact conformation, rationally, it is easy to operate, expand the common with cooperation of part and external contracting part by interior
With, complete simultaneously to carry out the port of cast part Inner expansions and the operation of external contracting, disposably complete, high working efficiency.
