Abstract
The invention relates to a dual-thrust electromagnet in which an armature is capable of moving straight. The electromagnet has a structure that two electromagnetic coils are provided at two left and right moving cores passing through an inner cavity of a columnar housing of the dual-thrust electromagnet, end lids are fixed and connected to two end ports of the housing respectively, core axes on the moving cores is passed through centre holes of the end lids, an improvement is that the housing is a two-body structure with a magnet isolation state at a middle portion. The housing the electromagnet is made to the two-body structure of the magnet isolation state, thereby magnetic force lines of two magnetic fields generated by electrifying the two electromagnetic coils can not pass through the housing to effect on one another, thereby avoiding a phenomenon that the magnetic forces in the housing are quits, so that the two magnetic fields have no mutual interference and influence. The dual-thrust electromagnet of the invention has a small volume, a big pushing force, can be used in a plurality of machines, devices or apparatus which can not use a brake electromagnet due to limitation of space and volume.
Description
Technical field
But the present invention relates to the electromagnet that a kind of armature straight line moves, specifically a kind of dual-push electromagnetic iron.
Background technology
Traditional dual-push electromagnetic iron, its structure is the moving core (armature) that is installed with left and right two symmetries in the inner chamber of tubular shell, and be provided with left and right two solenoids, two-port at housing is fastenedly connected with end cap (yoke) by screw respectively, mandrel on the moving core passes the centre bore of end cap, is connected with controller in outside.The housing of this dual-push electromagnetic iron is integrally manufactured overall structure.
The operation principle of electromagnet is, when solenoid is switched on, around coil, generate an electromagnetic field, the magnetic line of force passes solenoid, housing, end cap (yoke) and moving core (armature), form the closed-loop path, just form the N utmost point and the S utmost point respectively at the medial surface of end cap and the lateral surface of moving core.Under powerful the action of a magnetic field, moving core overcomes the elastic force of outer casing spring on mandrel, and outer rapidly moving is with the end cap adhesive.The mandrel that passes end cap central bore outwards produces a correlation displacement thereupon, thereby promotes corresponding mechanism action.For dual-push electromagnetic iron, owing to need two moving cores to produce extrapolability to both sides respectively when energising, therefore two magnetic fields that solenoid produced also should be that direction is opposite.And because the magnetic line of force of two opposing magnetic fields all need pass housing formation magnetic loop, thereby the state that repels each other of two magnetic field magnetic lines in both sides will appear in the housing stage casing, its result will inevitably slacken the magnetic field intensity in two magnetic fields, cause reducing of electromagnetic actuation power, electromagnetic actuation is kept electric current (or voltage) and is increased, and power consumption increases.In addition, because the adhesive action of two moving cores is arranged in dual-push electromagnetic iron, thereby its action noise is also bigger.
Summary of the invention
Purpose of the present invention just provides the more rational novel dual-push electromagnetic iron of a kind of structure, with power consumption and the volume that reduces electromagnet, reduces the action noise.
The present invention is achieved in that and is installed with left and right two moving cores in the inner chamber of the tubular shell of dual-push electromagnetic iron, be provided with two solenoids, two-port at housing is fixedly connected with end cap respectively, mandrel on the moving core passes the centre bore of end cap, and institute's improvements are that housing is that the middle part is two body structures every magnetic state.
The housing of electromagnet is made for two body structures every magnetic state, then the magnetic line of force of two electromagnetic fields that produced by the energising of two solenoids just can not have influence on the other side by the magnetic conduction effect of housing, so just avoided in housing because of the magnetic line of force phenomenon that the magnetic force that caused cancels out each other of repelling each other, make two magnetic fields not disturb mutually, be independent of each other.Like this, under the condition of identical attract current (or voltage), the suction-combining force of dual-push electromagnetic iron of the present invention just must increase.If still keep original electromagnetic actuation power constant, then the required electric current (or voltage) of keeping of electromagnet just must reduce, and reaches energy saving purposes thus.Show that through experiment test under the condition of identical structure, size and attract current, the suction-combining force of dual-push electromagnetic iron of the present invention can increase more than 30%; If keep identical the suction-combining force, then the volume of dual-push electromagnetic iron of the present invention can corresponding minimizing 30-40%.Also can be made into the braking dual-push electromagnetic iron that a kind of volume is little, thrust is big thus.Like this, just can be at a lot of original structure letter, braking electromagnets that cost is low of using on can't machine, equipment or the device of brake application electromagnet because of the spatial volume restriction, to reduce the manufacturing cost of correlation machine, equipment or device, improve the functional reliability of correlation machine, equipment or device.Expanded the application of electromagnet thus.
The present invention can also realize like this: at the medial surface of end cap or the lateral surface of moving core, and some bolsters of pegging graft vertically, the medial surface of the outstanding end cap in the outer end of bolster or the lateral surface of moving core.Like this, when moving core (armature) after energising with the impact moment of end cap (yoke) medial surface adhesive, the bolster that at first is evagination contacts with the lateral surface of moving core or the medial surface of end cap, with after the bolster compression, just can realize the adhesive that contacts of electromagnet armature and yoke.Thus,, just avoided the direct rigid collision formula adhesive of moving core and end cap, the inevitable obviously reduction of its action noise by bolster is set.
