Technical field
This utility model relates to a kind of electric magnet, particularly relates to the dynamic iron core electric magnet of a kind of little inertia helix tube type bi-material layers.
Background technology
As one of critical component in electrohydraulic proportional controller part, the function of proportion electro-magnet is the current signal converting to force or displacement that Proportional Amplifer are inputted. Therefore, the displacement force characteristic of electro-hydraulic proportional control technology comparative example electric magnet proposes strict requirement, and namely proportion electro-magnet must possess the displacement force characteristic curve of level, in its effective impulse stroke, when coil current one timing, its power output keeps constant, and unrelated with the displacement of armature.
Existing proportion electro-magnet is by plastic end cover, guide pin bushing, yoke, control coil, magnetism-isolating loop, basin shape pole shoe, valve interface block, push rod, magnetism isolating spacer, armature and end cap interface block composition, wherein except plastic end cover, magnetism-isolating loop, control coil, push rod, magnetism isolating spacer, remaining parts is made by permeability magnetic material. The magnetic line of force produced by coil during the work of this proportion electro-magnet working gas gap through between armature and valve interface block is divided into two branch road Φ 1 and Φ 2, wherein Φ 1 branch road is through armature axially through the working gas gap bottom basin shape pole shoe, returns to armature form Guan Bi ring then through valve interface block, yoke, guide pin bushing; Φ 2 branch road, through the oblique tapered peripheral by basin shape pole shoe of armature, arrives guide pin bushing front end, returns to armature form Guan Bi ring then through valve interface block, yoke, guide pin bushing.
Existing proportion electro-magnet relies primarily on the basin shape pole shoe of special shape and the magnetic line of force is divided into two branch roads, by the relative size of relative dimensions adjustment the produced axial magnetic component of two magnetic line of force branch roads of basin shape pole shoe, thus producing the range of linearity (i.e. the impulse stroke of proportion electro-magnet) of one section of level of approximation on the displacement force curve of armature. What adopt due to the armature of existing proportion electro-magnet is the good metal material of magnetic property, and is solid, and therefore self ratio is great, cause that it needs rapid-action occasion at some, response time is longer, and displacement force characteristics linearity degree is also poor, it is impossible to meet requirement.
Summary of the invention
The purpose of this utility model is in that to provide the dynamic iron core electric magnet of little inertia helix tube type bi-material layers that a kind of displacement force characteristics linearity degree is better, response time is shorter.
The dynamic iron core electric magnet of the little inertia helix tube type bi-material layers that this utility model provides includes guide pin bushing, yoke, control coil, magnetism-isolating loop, valve interface block, push rod and armature, armature, valve interface block and control coil are installed in yoke, wherein armature and valve interface block are distributed before and after vertically, control coil is positioned at armature and the outside of valve interface block, guide pin bushing and magnetism-isolating loop are located at armature, between valve interface block and control coil, push rod is connected on armature and traverse valve interface block, guide pin bushing includes leading portion guide pin bushing and back segment guide pin bushing, before magnetism-isolating loop is positioned at, between back segment guide pin bushing, described armature is connected and composed by iron core and nonmetallic core, nonmetallic core is connected to iron core one end away from push rod.
One end processing of above-mentioned iron core has stud, and one end processing of nonmetallic core has screw, iron core and nonmetallic core to be connected by the cooperation of stud and screw.
One end of above-mentioned iron core and nonmetallic core is all processed as odontoid, iron core and nonmetallic core and is connected by the cooperation of its teethed end faces.
Above-mentioned nonmetallic core is axially inside processed porose.
This utility model is under the premise not changing the basic structure of existing proportion electro-magnet, profile and interface size, connect and compose by iron core and nonmetallic core by armature is adopted, the quality of armature can be reduced, and make self magnetic conduction of armature rear portion reduce to zero, thus the linearity of proportion electro-magnet displacement force characteristic can be improved, reduce response time.
