Summary of the invention

The purpose of this utility model provides a kind of drill pipe connecting sleeve extrusion hydraulic machine with frame deflection compensation device, with accurate, the stable and reliability of drill pipe connecting sleeve mould matched moulds in the assurance work.

Technical solution of the present utility model is: it comprises C shape open side type frame, the vertical oil cylinder of installing in the middle part of frame is put the beams in place, the upper bolster that vertical oil cylinder piston bar bottom connects, the frame underbeam is the die shoe of installing on the workbench, the horizontal extrusion oil cylinder of installing in the framework pillar at the mould axial centre, the cross sliding clock that the piston rod leading section of horizontal extrusion oil cylinder connects, the extruding tringle adapter sleeve that the cross sliding clock leading section connects, and bulb is made in its vertical oil cylinder piston bar bottom, bulb is connected with upper bolster by the ball pivot seat, on four jiaos of the upper bolsters four guide pillars that are upward through the horizontal gusset guide hole of upper beam are installed also, flipper guide before other is provided with one, fixedly connected with the front side of upper bolster in its bottom, medial surface is respectively equipped with the vertical slide rail that matches with the vertical surface rail installed on the medial extremity before the biside plate of putting the beams in place.

The beneficial effects of the utility model are: four guide pillars of upper bolster setting have guaranteed the basic fixed position of upper bolster, its flipper guide stablized further again upper bolster about to the location, when the deformation of the stressed generation upper beam of work mid frame deflection angle, the ball pivot bindiny mechanism of vertical oil cylinder piston bar and upper bolster has then compensated the deformation of frame upper beam deflection angle automatically, thereby guaranteed the accurate matched moulds of patrix and counterdie, guaranteed product processing quality.The utility model is rational in infrastructure, the repetitive positioning accuracy height, and each moving component is equipped with automatic lubrication installation, and motion is nimbly and freely, and is reliable and stable, easy and simple to handle.
