Being improved to of technique scheme: described punch includes profile alignment punch and is positioned at the four directions extruding punch in the middle of profile alignment punch, described punch retainer includes profile alignment punch retainer and is positioned at the four directions extruding punch retainer above profile alignment punch retainer, described punch is also arranged above upper padding plate, and described upper padding plate is between punch and mould bases；Described die includes profile alignment die and is positioned at eight corner angle alignment dies below profile alignment die, and described die periphery is provided with die outer ring, and periphery, described die outer ring is provided with die fixed cover, and described die fixed cover is also arranged above die trim ring.
Being improved to of technique scheme: described profile alignment punch can slide up and down in profile alignment punch retainer.
Being improved to of technique scheme: be provided with spring between described profile alignment punch and mould bases.
Being improved to of technique scheme: be additionally provided with on described die fixed cover for adjusting the adjustment bolt of axiality between profile alignment punch and profile alignment die.
Being improved to of technique scheme: described mould bases bottom center is provided with through hole, described push rod is arranged in through hole by nut.
The present invention solves that the technical scheme two that above-mentioned technical problem proposes is: a kind of stopper ring production method, use stopper ring described in technical scheme one to shape shaping mould, comprise the following steps:
A) satisfactory bar is selected；
B) bar is placed on upset shaping on Cold header or cold pier mould；
C) bar of upset shaping is placed on bench drill, forms extrusion blank in bar central bore reaming；
D) extrusion blank is placed in profile alignment die, control profile alignment punch descending, under the action of the spring extrusion blank is clamp-oned in profile alignment die and eight corner angle alignment dies, when profile alignment punch upper surface contacts with extruding punch retainer lower surface, four directions, extruding force becomes big, and profile alignment punch extrudes blank extrusion molding shaping together with punch with four directions；
E) control punch up, utilize push rod by the stopper ring demoulding.
Present invention employs stopper ring and shape shaping mould structure, compared with prior art, its advantage is: punch is optimized by the present invention with cavity die structure, have employed floating fixed structure, it is provided with spring between profile alignment punch and mould bases, profile alignment punch can slide up and down in profile alignment punch retainer, thus extends the mold use life-span；The present invention additionally uses certain moduli lamps structure, makes four square holes shape and completes with profile shaping simultaneously, i.e. completes the once-forming of stopper ring, it is ensured that workpiece quality requirement, improve production efficiency, reduce production cost；Present configuration design is ingenious, and it is convenient to change.
