Embodiment
Structure of the present utility model is referring to Fig. 1,2,3,4,5.By being fixed on electric direct-drive type forcing press linear motor stator electric (2) on hydropress frame (1), be fixed on two pairs of slide blocks (3) on stator (2), be fixed on disk type electromagnetic clutch (4) on stator (2), be fixed on safety anti-falling device (5), the pair of tracks (6) matching with slide block (3) on stator (2), be fixed on the mover (7) that track (6) moves up and down with respect to stator (2) and the brake assemblies (8) being fixed on mover (7) forms; The assembly of mover (7), track (6) and brake assemblies (8) component movement, under the control of track (6) and slide block (3), move up and down, the hydraulic cylinder that is equivalent to hydraulic system, has fully phased out hydraulic pump, hydraulic oil container, electro hydraulic valve, hydraulic cylinder, fluid pressure line and hydraulic pressure wet goods.
Stator (2) is comprised of three-phase winding iron core and the iron-core coil of two groups of symmetries, and described mover (7) is between the three-phase winding iron core and iron-core coil of two groups of symmetries; Coil passes to three-phase alternating current and in stator winding, produces travelling-magnetic-field; Mover (7) is comprised of mover iron core, two-sided mouse cage winding; When stator travelling-magnetic-field and mover have relative motion, (while having slip) cuts the travelling-magnetic-field magnetic line of force in mover winding, the two-sided mouse cage winding of mover sliver will produce induced potential and electric current, the electric current of all slivers and air gap magnetic field interaction, just produce tangential electromagnetic force, be up to 100KN.Stroke two ends at mover (7) are provided with limit switch.
Slide block described in the utility model (3), electromagnetic clutch (4), safety anti-falling device (5), track (6), be outsourcing piece.Hydropress frame (1) is the member of conventional forcing press.
The two cover disc type electromagnetic clutchs (4) that are fixed on stator (2) top be electric release, without electric brake structure, be fixed on two cover safety anti-falling devices (5) of stator (2) top and be fixed on the upper brake assemblies of mover (7) and form stall guard system.When electric direct-drive type forcing press linear electric motors are not worked, disc type electromagnetic clutch (4) no power does not make mover (7) locking guarantee that it does not fall.Other equal no powers in any position, realize energy-conservation;
When electric direct-drive type forcing press linear electric motors work declines, first give the three-phase alternating current of the logical certain electric current of three phase windings of stator (2), make it produce power upwards, can overcome mover (7) deadweight, under the effect of electromagnetism, keep mover (7) relatively stable, then giving disk type electromagnetic clutch (4) electricity, is the electric energy feedback to power-supply system when mover is transferred.If surpass setting speed 0.3-0.5 meter per second at the situation lowering velocity to electrical network feedback, disk type electromagnetic clutch (4) dead electricity brake automatically, even if disk type electromagnetic clutch (4) lost efficacy, when mover (7) lowering velocity surpasses 0.67 meter per second, being arranged in addition safety anti-falling device (5) action being in time fixed on stator (2) locks mover (7), at this moment needing people is that release can be cancelled locking, determines safety; When touching by pressure object, the movement velocity of mover (7) can decline, the slip meeting of at this moment producing travelling-magnetic-field and mover (7) in stator (2) winding increases, thereby increased the electric current of stator (2) three phase windings, realized maximum thrust 100KN.Can keep this electric current no longer to increase reaching maximum current Time Controller, guarantee that motor winding can not burn.
When rising, electric direct-drive type forcing press linear electric motors work first to three phase windings of stator (2), leads to the three-phase alternating current of certain electric current, make it produce power upwards, can overcome mover (7) deadweight, under the effect of electromagnetism, keep mover (7) relatively stable, then give disk type electromagnetic clutch (4) electricity, it is discharged, and the electric current that then now increases by three phase windings of stator (2) makes it by certain speed, rise.
No matter be at lower liter and corresponding limit switch action while dropping to extreme position, all can make disk type electromagnetic clutch (4) and stator winding dead electricity lock.
