Abstract
A lifting permanent magnet.
The shell (2) coats the permanent magnet (1), the coils (9) and (15), the annular plug (8), the circular ring irons (4) and (14), the cylindrical iron (13), the annular manganese plate (6) and the circular plate (7), and the annular plug (8) goes up and down through the armature (11) of the lifting electromagnet (12), the lever (10) and the connecting rod (5).
The utility model discloses utilize the hard magnetism of permanent magnet to inhale the material, and the blowing mode does not rely on reverse demagnetization to effectual reverse demagnetization and the front of having avoided the permanent magnet two some defects do simultaneously and produce the place in order to satisfy the strong magnetic force of requirement in its inside rethread coil current.
Description
The utility model belongs to hoisting permanent magnet
At present the hoisting DC electromagnet that generally uses all is the soft magnetic material of usefulness, produces magnetic field and works passing to coil current.There are two defectives in it like this, and the firstth, consumption of current is big, and the secondth, dangerous, if dead electricity once in a while, the iron charge of being inhaled will fall, and cause the accident.In order to obey this two defectives, occurred again on the market planting later-model lifting permanent magnet solenoid, but its blowing mode will be with backing field to the permanent magnet demagnetization.So whenever after dashing magnetic, can only use for demagnetization several times, and the magnetic force after the demagnetization reduces manyly than magnetic force before the demagnetization not at every turn, thereby efficient is very low, and is pretty troublesome again.
The purpose of this utility model is design a kind of hard magnetic suction that utilizes permanent magnet, and the blowing mode not to rely on the hoisting permanent magnet of reverse demagnetization.
Accompanying drawing 1 is the non-adjustable hoisting permanent magnet constructional drawing of magnetic force
Accompanying drawing 2 is the adjustable hoisting permanent magnet constructional drawing of magnetic force
Accompanying drawing 3 is a permanent magnet Lift Part constructional drawing
The purpose of this utility model and embodiment are described below with reference to the accompanying drawings
Shell (2) is with permanent magnet (1), coil (9), (15), ring plug (8), annulus iron (4), (14), cylindricality iron (13), annular manganese plate (6), in plectane (7) was coated on, ring plug (8) was through the armature (11) of lifting electromagnet (12), lever (10), bar (5) lifting
An elastic body (17) is established in armature (11) lower end of lifting electromagnet (12), and an end of lever (10) is a fulcrum.
The utility model utilizes the hard magnetic suction of permanent magnet, and the blowing mode does not rely on reverse demagnetization, thereby actv. has been avoided the reverse demagnetization and foregoing two point defects of permanent magnet, simultaneously also within it portion pass to coil current again and produce the place of magnetic field with the strong magnetic force that meets the demands.
Embodiment
When ring plug (8) is in the lifting state, when promptly whole magnetic circuit is in open loop, adorns enough and produces magnetic force to external world, when ring plug (8) closure, device does not promptly have magnetic force to external world.Simultaneously still be wound with the coil (9) of some with standby in inside.Magnetic force is adjustable plays hoisting permanent magnet, and its structure is roughly to last similar, just permanent magnet be cylinder (13) on it around more coil (15), the regulating winding electric current had both been regulated the electric current of ring plug opening part, thereby reached the adjusting in magnetic field.
Claims (2)
1, hoisting permanent magnet is characterized in that:
Shell (2) is permanent magnet (1), coil (9), (15), ring plug (8), annulus iron (4), (14), cylindricality iron (13), annular manganese plate (6), in plectane (7) was coated on, ring plug (8) was through the armature (11) of lifting electromagnet (12), lever (10), bar (5) lifting
2, hoisting permanent magnet according to claim 1 is characterized in that;
An elastic body (17) is established in armature (11) lower end of lifting electromagnet (12), and an end of lever (10) is a fulcrum.
