Abstract
The utility model relates to a magnetizing clamping device, comprising a magnetizing clamping head and a coil. The utility model is characterized in that an annular magnet yoke 2 is radically and uniformly distributed with more than a couple of magnetizing clamping heads 1, the magnetizing clamping head 1 is sheathed with a coil framework 4, and the framework 4 is wound with a coil 3. The utility model can be used for entire magnetizing and magnetic saturation, the maximum magnetostatic moment of a magnetic coupler can be increased, and horse power can be stronger without demagnetization problem. The utility model assures processing quality of workpieces, so a magnetic force driving pump can be widely used for transporting the media with large specific gravity and large viscosity.
Description
The utility model relates to a kind of frock that magnetizes, and exactly is a kind of multi-electrode fixture for magnetization.
Existing fluoroplastics magnetic force driven centrifugal pump is that plastic packaging was made the movable sealing of magnetic coupling (internal rotor) with static seal replacement centrifugal pump after permanent magnet elder generation monolithic was magnetized, and the pump dropping liquid is not leaked.But its internal rotor iron core all adopts semiclosed moulding, and axle leans on the sealing of rotor core that band is moulded in the tetrafluoro life, the O RunddichtringO is finished.The deficiency of its existence is, a sealing property is unreliable, is easy to generate leakage, the corrosion iron core, and magnet also loses magnetic field very soon, causes afunction; Two, internal rotor magnet major part is all selected magnetic materials such as cerium cobalt copper iron, SmCo for use, and these material properties are low, price is high, driving torque is little; When pumped (conveying) medium proportion, viscosity were big, then not defective such as fluid of slippage, stall, demagnetization, pump appearred in magnetic coupler.The a kind of of development in recent years is the novel permanent magnetic material of base with the neodymium iron boron, has advantages such as high-coercive force, low price, and its shortcoming is that Curie temperature is low, is 350-370 ℃.And the forming temperature of fluoroplastics is 335～345 ℃, if sintering again after magnetizing with conventional method will cause its demagnetization rate to reach 80%, in order to solve this weakness, must magnetize after the plastic packaging protection of magnet elder generation.
The purpose of this utility model is: for solving the deficiency of above-mentioned technology, provide a kind of and can realize the plastic packaging protection with magnet elder generation, the multi-electrode fixture for magnetization that magnetizes again.
The structure technology scheme that realizes the multi-electrode fixture for magnetization of above-mentioned purpose is such.
Multi-electrode fixture for magnetization comprises coil, the chuck that magnetizes, and it is characterized in that: the footpath of the magnetic conduction iron yoke 2 of annular uniform the chuck 1 that magnetizes more than two pairs that makes progress; The chuck 1 of magnetizing is cylindricality, and its front portion is positioned at the ring of annular magnetic conduction iron yoke 2, its front axle sheathed coil rack 4 that makes progress, and coil 3 in winding on the coil rack 4.
The integral body that these anchor clamps are used for high-performance rare-earth alloy NdFeB material rotor magnetizes and carries out magnetic saturation, and the maximum magnetostatic moment of magnetic coupler is improved greatly, and horsepower is more powerful, and complete machine performance and quality have obtained breakthrough raising; Do not have the demagnetization problem in the use, guaranteed workpiece quality, its 2-9 can evenly produce the pulsed magnetic field of 80-2400 kilo-ampere/rice to the chuck that magnetizes; And the volume of internal rotor reduces, weight saving, and cost descends.Make magnetic force driving pump can be widely used in the medium that delivery ratio is great, viscosity is big.
Fig. 1 is the utility model structural representation,
Fig. 2 is the cutaway view of Fig. 1,
Fig. 3 is the winding wiring figure that magnetizes.
Below in conjunction with accompanying drawing, the utility model is done to say further by embodiment.
Multi-electrode fixture for magnetization comprises magnetic conduction iron yoke 2, the chuck 1 that magnetizes, coil rack 4 and coil 3.The footpath of magnetic conduction iron yoke 2 of the annular uniform four pairs of chucks 1 that magnetize that are installed with that make progress are seen Fig. 1; The chuck 1 of magnetizing is cylindricality, and the ring that is positioned at annular magnetic conduction iron yoke 2 is stretched in its front portion, is positioned on the chuck 1 that magnetizes of annular magnetic conduction iron yoke 2 rings suit and coil rack 4, and coil 3 in winding on the coil rack 4.Coil 3 is by wiring shown in Figure 3.
In the use, two connector lugs of multi-electrode fixture for magnetization are received on the binding post of magnet charger, four couple who again workpiece of cylindricality is put into clamp body is magnetized between the chuck 1, and energized can magnetize to workpiece.
