4. judging the ball-type section of installation by the type, curvature, height dimension of required compacted part;By fixed when assembling Mold assembling is completed in the insertion and positioning of bit architecture 4 and location structure 5;Then each section is fastened with bolt, makes it in pressing process In not will produce dislocation and relative movement;
5. after set of molds fills, mobile work platform to Working position is central by mold and oil pressure machine equipment with T shapes screw Sliding block is clamped to be fixed with hydraulic press, is moved downward by equipment and is started thermoforming compacting;
6. if you need to suppress conical head 9, section 2 in spherical shape is connect by bracket with oil pressure machine equipment center sliding block, is adjusted Section 2 and lower die 8, make its gap uniformity in spherical shape;
7. if you need to suppress dome head 11 or the approximate segment seal head of specification, it is only necessary to, will be corresponding according to above-mentioned steps Spherical node is assembled and is fastened;
8. forming blank, is heated to 930 DEG C ~ 950 DEG C, soaking time 1.5 by heating and compacting blank in heat-treatment furnace Minute/mm, the end socket for compression moulding of then coming out of the stove;The pressure that begins temperature is higher than 880 DEG C, and final pressure temperature is higher than 770 DEG C;Discharge temp 700 DEG C ~ 720 DEG C, complete part compacting;
After 9. end socket is suppressed, mobile work platform to position capable of hoisting unclamps the fastener between each spherical node, according to secondary Each component of mold is hung workbench and is under lock and key by sequence, and antirust oil guard is smeared in location structure part.
The beneficial effects of the utility model:Solves solid punch diameter and the technical issues of tonnage is difficult to lift very much greatly; Suitable for Dn3500 ~ 8000mm, the big thick end socket heat stamping and shaping of wall thickness >=60mm;Have a wide range of application, a variety of shapes can be suppressed The end socket of shape specification;Structure novel reduces cost.
