Description
Technical field:
The utility model relates to a kind of device that steel pipe is carried out shaping and undergauge.
Background technology:
Because the steel grade of steel of each steel mill's production generally improves at present, so do not reach the physical dimension requirement with big wall thickness, the high grade of steel steel pipe majority of existing equipment processing, product quality can not get guaranteeing.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of size reducing machine that can carry out shaping and undergauge to big wall thickness, high grade of steel steel pipe.
Above-mentioned purpose is achieved in that it comprises main frame, and respectively there is one set of lifting mechanism the main frame both sides.
Main frame comprises frame, the plunger of master cylinder is fixed by bolts on the frame, on the frame of master cylinder both sides, be fixed with kicker cylinder, below master cylinder and the kicker cylinder upper beam is arranged, upper beam is connected and fixed with the piston rod of master cylinder cylinder body and kicker cylinder, following and the mold seat of putting the beams in place welds together, mold is contained in the mold seat, with pressing plate and bolting, bed die is contained in the bed die seat, also use pressing plate and bolting, the bed die seat is fixed on the underbeam, and underbeam is by being bolted to frame lower;
Elevating mechanism comprises stand, is connected with two sliding sleeves below the stand, and hydraulic cylinder all is housed in each sliding sleeve, hydraulic cylinder piston rod and sliding sleeve upper articulation, and the hydraulic cylinder body bottom-hinged is on fairlead, and fairlead is fixed on the ground; Some groups of tapered rollers are housed above the stand, and each two ends of organizing tapered roller is contained on the bearing block of oneself respectively, and each bearing block is separately fixed on the stand, and every group of tapered roller one end all is connected with motor on the bearing block that is fixed on oneself; The symmetrical centre of the tapered roller of main frame both sides elevating mechanism is consistent with the mould symmetrical centre on the main frame.
The utility model has the advantages that and to carry out shaping and undergauge to big wall thickness, high grade of steel steel pipe that make it reach the physical dimension requirement, product quality is guaranteed with existing equipment processing.
Description of drawings:
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is that the motor that amplifies and tapered roller are contained in the structural representation on the bearing block;
Fig. 3 is the left view of Fig. 1 of amplification.
The specific embodiment:
With reference to Fig. 1-3, it comprises main frame, and respectively there is one set of lifting mechanism the main frame both sides.
Main frame comprises frame 1, the plunger 2 of master cylinder 3 is fixed by bolts on the frame, on the frame of master cylinder both sides, be fixed with kicker cylinder 4, have below master cylinder and the kicker cylinder and put the beams in place 5, upper beam is connected and fixed with the piston rod of master cylinder cylinder body and kicker cylinder, following and the mold seat 6 of putting the beams in place welds together, mold 16 is contained in the mold seat, with pressing plate and bolting, bed die 17 is contained in the bed die seat 7, also use pressing plate and bolting, the bed die seat is fixed on the underbeam 8, and underbeam is by being bolted to frame lower; Elevating mechanism comprises stand 13, is connected with two sliding sleeves 10 below the stand, and hydraulic cylinder 11 all is housed in each sliding sleeve, hydraulic cylinder piston rod and sliding sleeve upper articulation, and the hydraulic cylinder body bottom-hinged is on fairlead 12, and fairlead is fixed on the ground 18; 4 groups or 5 groups or 6 groups of tapered rollers 9 are housed above the stand 13, and each two ends of organizing tapered roller is contained on the bearing block 14 of oneself respectively, and each bearing block is separately fixed on the stand, and every group of tapered roller one end all is connected with motor 15 on the bearing block that is fixed on oneself; The symmetrical centre of the tapered roller of main frame both sides elevating mechanism is consistent with the mould symmetrical centre on the main frame.
Operation principle: in order to improve pressure, be convenient to steel pipe is carried out shaping and undergauge, can take the steel pipe segmentation is carried out the way of shaping and undergauge.During work, tapered roller machine operation on the stand of elevating mechanism, steel pipe on the roller-way is transported on the stand, hydraulic cylinder works below the stand, quit work after steel pipe moved on to the appropriate location, the tapered roller motor works on, steel pipe is sent in the mould of main frame, the hydraulic cylinder below the stand descends, and steel pipe is placed on the bed die, hydraulic cylinder continues to descend back original position, the master cylinder and the kicker cylinder of main frame are started working, and drive upper bolster, mold move down, and push down steel pipe, master cylinder pressurization then, pressurize certain hour behind the mould matched moulds.The master cylinder release, the kicker cylinder return, drive master cylinder, upper bolster, mold is got back to original position, kicker cylinder quits work, hydraulic cylinder on the elevating mechanism stand of main frame both sides moves simultaneously, with steel pipe jack-up, steel pipe is broken away from stop behind the mould certain altitude and move, the tapered roller motor on the elevating mechanism stand of main frame both sides is worked simultaneously, after steel pipe moved forward a step pitch, this motor stops operating, and the hydraulic cylinder synchronous on the stand of both sides descends, and steel pipe is placed on the bed die, hydraulic cylinder continues to drop to original position, master cylinder on the main frame, kicker cylinder work drives upper bolster, mold moves down, and carries out the pressure pipe second time, it is the master cylinder pressurization, pressurize certain hour behind the matched moulds, master cylinder release then, kicker cylinder return, master cylinder, upper bolster, mold is got back to original position, kicker cylinder quits work, and the hydraulic cylinder below the stand of both sides elevating mechanism moves simultaneously, with steel pipe jack-up ... carry out next step pressure pipe.
After the steel pipe end has been pressed, the steel pipe center of gravity moves on on the stand of a side, and the hydraulic cylinder below this side stage frame rises, with steel pipe jack-up behind certain altitude, move on stopping, tapered roller machine operation on this stand all moves on to steel pipe on this stand, and motor stops operating, hydraulic cylinder works, the height of the tapered roller on the stand and the height of the tapered roller on the roller-way are consistent, and the machine operation on the tapered roller shifts out size reducing machine to steel pipe.
