Background technology
Drill pipe connecting sleeve is a kind of bottle stopper shape cylindrical member, and the turning processing molding method that it is traditional is not only time-consuming, and waste of raw materials is big.Intend adopting hot extrusion molding method for this reason, the moulding process principle of this method as shown in Figures 1 and 2, to place the lower cavity die f of die shoe h through the drill pipe connecting sleeve blank g that offers centre bore of preheating by axial level earlier, upper cavity die c then closely firmly matches with lower cavity die f by the upper bolster b that is connected with the piston rod a of vertical oil cylinder, blank centre bore in mould insertion extruding tringle also is punch d then, and the tail end of this punch is connected with the piston rod e of horizontal extrusion oil cylinder.For realizing above-mentioned moulding process, adopt C shape hydraulic single column press comparatively suitable, being about to described upper cavity die is installed on the upper bolster that the vertical oil cylinder piston bar bottom of C-form stand in putting the beams in place connected, the underbeam that lower cavity die is installed on C-form stand is on the die shoe of workbench, horizontal extrusion oil cylinder at the mould axial centre is installed in the column of frame, and the piston rod leading section of horizontal extrusion oil cylinder connects punch.But the hydraulic press of this machine and traditional C shape fuselage is the same to be the cantilever force structure, vertical oil cylinder in being installed on upper beam promotes upper bolster and patrix downwards and during the lower cavity die matched moulds of die shoe, upper beam promptly is subjected to a reaction force that makes progress and produces the certain rigid distortion, promptly put the beams in place and produce certain deflection angle, thereby influence the precision and the product processing quality of matched moulds.
Summary of the invention
Purpose of the present invention 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 invention 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 invention has the beneficial effects as follows: 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 present invention 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.
