The utility model compared with the prior art, its advantage is:
1. process applications is wide.The utility model has four groups of wedge shape operating mechanisms, produce and the corresponding and needed matched moulds thrust of institute's forging pipe joint number of passages, in the work, only need to change upper and lower two halves die and drift, just can die forging two logical, threeway and four-way union;
2. can the die forging shape more complicated forging, metal material is more saved.The utility model adopts the rigidity discharger, drift can be extracted from the hole of forging, so the darker endoporus of energy upsetting squeeze and the dome platform of pipe joint threaded portion;
3. closing precision height.Because four groups of guide pillars fixedly are housed on upper and lower template, in the course of the work, the upper, middle, and lower part of whole device carried out lead, thereby upper and lower two halves die can not produce offsetting, guaranteed the closing precision of upper and lower two halves die.Simultaneously, can also bear asymmetric horizontal component;
4. need on employed equipment, not add backing-out punch, save cost of equipment.
