Abstract

A kind of integrated dc electromagnet is characterized in that numerous iron core column 1 is arranged on the same yoke 2, and these iron core column 1, yoke 2 are one, and iron core column 1 disposes magnetizing coil, armature, reaction spring respectively, constitutes integrated dc electromagnet colony.Its advantage is: easy to process, and the precision height, cost is low, and volume is little, is applicable to multiple occasions such as the automatic card-punching machine of weaving industry, electronic jacquard machine.

Description

Integrated dc electromagnet

The present invention relates to a kind of DC electromagnet.

DC electromagnet commonly used is a discrete, each DC electromagnet is made up of an iron core column, a yoke, a magnetizing coil, an armature and a reaction spring, wherein magnetizing coil is sleeved on the iron core column, when magnetizing coil is switched on, the armature adhesive, when the magnetizing coil no power, then armature breaks away from iron core column.Under some specific occasions, need numerous DC electromagnet is arranged in together, be used to finish predetermined actions, adopt existing DC electromagnet this moment, has defectives such as occupation space is big, processing cost is high, installation is inconvenient, poor reliability.

The object of the present invention is to provide a kind of integrated dc electromagnet, the iron core column of numerous DC electromagnet is arranged on the same yoke, and these iron core column, yoke are one, adopt a soft iron to make, each iron core column disposes magnetizing coil, armature and reaction spring respectively, constitutes integrated dc electromagnet colony.

Integrated dc electromagnet of the present invention, comprise iron core column 1, yoke 2, magnetizing coil 3, armature 4, reaction spring 5, magnetizing coil 3 are sleeved on the iron core column 1, when magnetizing coil 3 energisings, armature 4 is by iron core column 1 adhesive, during magnetizing coil 3 no powers, armature 4 breaks away from iron core column 1, it is characterized in that: numerous iron core column 1 is arranged on the same yoke 2, and these iron core column 1 are one with yoke 2, make with a soft iron, each iron core column 1 disposes magnetizing coil 3, armature 4, reaction spring 5 respectively, constitutes integrated dc electromagnet colony; Described iron core column 1 is cuboid or cylinder.

With prior art relatively, the present invention has the following advantages:

1. easy to process, on a soft iron, process the iron core column and the yoke of electromagnet colony simultaneously, working (machining) efficiency improves more than 5 times;

2. process and the assembly precision height, all iron core column, yoke parameter unanimity do not produce rigging error, the functional reliability height;

3. it is convenient to be used for whole machine installation, and it is little to take up room, needing to be particularly suitable for using on the complete machine of miniaturization, but than the prior art reduced volume more than 60%;

4. manufacturing cost is about 30% of a discrete electromagnet.
