Description
Technical field
The utility model relates to a kind of hydraulic valve DC electromagnet.
Background technology
The suction of hydraulic valve DC electromagnet and stroke square are inversely proportional to, and when impulse stroke is larger, initial electromagnetic attraction is less, in order to address this problem, in armature sleeve pipe, welding magnetism-isolating loop, by designing diverse location and the shape of magnetism-isolating loop, larger initial electromagnetic force can be obtained.For the determination of magnetism-isolating loop position and shape, accurately can be determined by simulation software during design, but be thin-walled parts due to armature sleeve pipe and need to bear certain pressure, magnetism-isolating loop accurately to be welded in armature sleeve pipe be but electromagnet manufacture in a critical technological point, armature sleeve pipe is thinner, and welding procedure is more difficult.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides the hydraulic valve DC electromagnet that a kind of structure is simple, cost is low, operating efficiency is high.
The technical scheme that the utility model solves the problem is: a kind of hydraulic valve DC electromagnet, comprise iron core, magnetic shield, armature, coil, electromagnet casing, iron core is nested in one end of magnetic shield, armature is nested in the other end of magnetic shield, the centre of armature built-in end is provided with cylindrical hole, cylindrical hole is embedded with stage clip, armature is free movement compression press spring in magnetic shield, iron core forms bracing frame together with magnetic shield, described coil winding forms coil block on bracing frame, and coil block, stage clip and armature entirety are nested in electromagnet casing.
In above-mentioned hydraulic valve DC electromagnet, described mandrel bottom is provided with plastic cushion, and plastic cushion is arranged in electromagnet casing lower end inner wall with fixed coil assembly, stage clip and armature.
In above-mentioned hydraulic valve DC electromagnet, the built-in end of described iron core is provided with groove, and described groove is inverted taper type, the two ends of described stage clip support bottom online cylindrical iron hole respectively and groove taper surface bottom.
In above-mentioned hydraulic valve DC electromagnet, described iron core and magnetic shield are interference fit.
In above-mentioned hydraulic valve DC electromagnet, described armature and magnetic shield are matched in clearance.
The beneficial effects of the utility model are:
1, iron core of the present utility model forms bracing frame together with magnetic shield, coil winding forms coil block on bracing frame, coil block, stage clip and armature entirety are nested in electromagnet casing, integral type magnetic shield is adopted to replace syllogic magnetism-isolating loop armature sleeve pipe, effectively solve the problem of processing technology difficulty, improve production efficiency;
2, the utility model adopts magnetic shield as the bracing frame of coil, decreases the coil retainer of conventional electromagnets, simplifies mechanism, reduce the radial dimension of electromagnet, thus reduce cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises iron core 2, magnetic shield 3, coil 4, armature 5, stage clip 6, electromagnet casing 7, iron core 2 interference fit is nested in one end of magnetic shield 3, armature 5 matched in clearance is nested in the other end of magnetic shield 3, the centre of armature 5 built-in end is provided with cylindrical hole 8, cylindrical hole 8 is embedded with stage clip 6, the built-in end of described iron core 2 is provided with groove, described groove is inverted taper type, the two ends of described stage clip 6 support bottom online cylindrical iron hole 8 respectively and groove taper surface bottom, armature 5 is free movement compression press spring 6 in magnetic shield 3, iron core 2 forms bracing frame together with magnetic shield 3, described coil 4 is wrapped on bracing frame and forms coil block, coil block, stage clip 6 and armature 5 entirety are nested in electromagnet casing 7, plastic cushion 1 is provided with bottom described iron core 2, plastic cushion 1 is arranged in electromagnet casing 7 lower end inner wall with fixed coil assembly, stage clip 6 and armature 5.When electromagnet is connected with certain electric current, under the effect of electromagnetic induction, the spring force that armature 5 can overcome stage clip 6 moves to iron core 2, and when electromagnet power-off, under the spring-force driven dual of stage clip 6, armature 5 can leave iron core 2.
