Part is more smooth during relatively moving.
Preferably, there is the Eversible structure that bore becomes larger, the Eversible structure to be used as the upper end of the tubing placed cavity
Structure is crossed, contributes to metal pipe material to turn up in flange face forming process.
Preferably, the diameter gradually narrow contracting downwards of the protrusion centring point, is conveniently inserted into the inner cavity of metal pipe material,
Be conducive to pipe end extruding simultaneously to turn up to form flange face.
Preferably, the lower die-sleeve is set in auxiliary sleeve, and the material returned bar to offset with lower die-sleeve is equipped in auxiliary sleeve；Institute
Auxiliary sleeve is stated on lower installation board.
Preferably, the Upper Die-sleeve is mounted on upper mounting plate.
Compared with prior art, the utility model has the advantages that：It provides a kind of applied to highly difficult cold
The branch pipe flanging die of extrusion process technology, by the flange face of mold cold-extrusion technology energy straight forming metal pipe material, together
Upper punch component split type Shi Caiyong, when demoulding, will not be there is a phenomenon where being adhered absorption, and simple in structure, the cost of material is low, adds
Work is efficient, safe.
