Embodiment Construction
[0030] see figure 1 , a kind of steel pipe hot extrusion machine center measurement, adjustment method of the present invention, it comprises the steps:
[0031] 1) Remove the mandrel and connecting rod on the mandrel beam 1, and leave the connecting thread at the bottom of the mandrel beam 1;
[0032] 2) Take the center of the connecting thread at the bottom of the mandrel beam 1 and the center of the front beam 8 as reference points, and pull the reference steel wire;
[0033] 3) Measure the concentricity deviation data of the extrusion die 6, the extrusion cylinder 5, and the extrusion beam 2 respectively with reference to the reference steel wire;
[0034] 4) By adjusting the installation positions of the extrusion die 6, the extrusion cylinder 5, and the extrusion beam 2, the concentricity deviation is adjusted to meet the technical requirements.
[0035] Preferably, the concentricity control between the extrusion die and the reference steel wire: less than 0.3mm; the c...
