Description

New electromagnet

Technical field

The utility model relates to a kind of new electromagnet.

Background technology

Electromagnet is wound around the coil matched with its power, and alive coil has magnetic as magnet.Electromagnet is widely used in electromagnetic relay, industrial automatic control, office automation, automation control appliance, package packing machine, medicine equipment, food machinery, textile machine etc.For textile machine, the normal electromagnet that uses carries out selecting the operation such as shuttle, needle selection.Existing electromagnet, in selecting shuttle, needle selection etc. to operate, need be energized, need energising during pushrod movement, push rod remains on the position of specifying and also will be energized always.Because electromagnet has electric current to pass through in the course of the work always, power consumption is large.And electromagnet is longer for conduction time, the heat that therefore coil produces is also more, has both affected the operational environment of electromagnet, also can bring potential safety hazard.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of new electromagnet of less energy consumption.

For realizing above object, the utility model is achieved through the following technical solutions:

New electromagnet, is characterized in that, comprises shell and push rod; Described push rod inserts in described shell, and can move relative to described shell; Armature is provided with in described shell; Described armature is connected with described push rod, drives described push rod to move; Two coils are also provided with in described shell; Described two coils arrange along the axis direction of described push rod; Each described coil is all around a part for described armature.

Preferably, also permanent magnet is provided with in described shell; Described permanent magnet is positioned on the mobile route of described armature.

Preferably, also yoke is provided with in described shell; Two described coils between described coil and described armature, and arrange by described yoke with connecting.

Preferably, described yoke comprises sleeve and boss; Described boss is set in the outer surface of described sleeve, along extending radially outwardly of described sleeve; After two described coils part respectively around described sleeve, the axis along described sleeve clamps described boss.

Preferably, two buting iron are also provided with in described shell; Described two buting iron are all arranged on the mobile route of described armature, and lay respectively at the both sides of described armature.

Preferably, one of them buting iron is provided with permanent magnet.

Preferably, described permanent magnet is magnet steel.

Preferably, described shell is all stretched out at the two ends of described push rod.

New electromagnet in the utility model, only need at push rod moving process to coil electricity, and when push rod remains on assigned address, coil can power-off, and power consumption reduces greatly, saves the use cost of new electromagnet.On the other hand, new electromagnet shortening conduction time, is no more than 5% of the new electromagnet operating time, and the heat that therefore coil produces also greatly reduces, and improves the operational environment of new electromagnet, improves coefficient of safety.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail:

As Figure 1-4, new electromagnet comprises shell 1 and push rod 2.Push rod 2 runs through shell 1 and shell 1 is stretched out at two ends.Armature 3 is provided with in shell 1.Armature 3 is set on push rod 2, and screw 31 inserts armature 3 rear screw-in push rod 2 along the radial direction of push rod 2, is connected by armature 3 with push rod 2.Armature 3 can drive push rod 2 to move along the axis direction of push rod 2 together.Also be provided with two coils in shell 1, be respectively the first coil 41 and the second coil 42.First coil 41 and the second coil 42 arrange along the axis direction of push rod 2, and respectively around a part for armature 3.

Yoke 5 is also provided with in shell 1.Yoke 5 comprises the first sleeve 51 and boss 52, and boss 52 extends along the radial direction of the first sleeve 51.After first coil 41 and the part of the second coil 42 respectively around the first sleeve 51, in the axial direction boss 52 is clamped.First sleeve 51 is around a part for armature 3.

Also be provided with two buting iron in shell 1, be respectively the first buting iron 61 and the second buting iron 62.First buting iron 61 and the second buting iron 62 are all arranged on the mobile route of armature 3, and lay respectively at the both sides of armature 3.Shell 1 is stretched out after the top and bottom of push rod 2 are each passed through the first buting iron 61 and the second buting iron 62.First buting iron 61 is provided with the first catch 611, second buting iron 62 and is provided with the second catch 621.Described first catch 611 and the second catch 621 are oppositely arranged, and respectively with shell 1 interference fit, coil clamp is held in shell 1.First buting iron 61 and the first buting iron 61 are provided with groove (not shown), and permanent magnet 7 embeds in groove.Permanent magnet 7 is magnet steel.

First coil 41 is communicated with extraneous power supply by wire 8 with the second coil 42.Wire 8 runs through shell 1, and through part is provided with gum cover 81, prevents the insulating barrier outside wire 8 and shell 1 from rear wearing and tearing of rubbing occurring, avoids electric leakage.

Push rod 2 and the first buting iron 61, between push rod 2 and the second buting iron 62, be equipped with copper sheathing 9, play guide effect, ensure that push rod 2 and armature 3 move along fixing path, avoid the wearing and tearing of push rod 2, first buting iron 61 and the second buting iron 62 simultaneously, extend the useful life of new electromagnet.

Coil is not energized, and armature 3, under the sucking action of permanent magnet 7, is resisted against on the first buting iron 61.

Second coil 42 is energized, and produces the second magnetic field.Armature 3 and the second buting iron 62 are magnetized, and produce relative magnetic pole.Armature 3 moves down under the attraction of the second buting iron 62, and drives push rod 2 to move down.In the process that armature 3 moves down, stoped at assigned address (as shown in Figure 4) by the second buting iron 62, push rod 2 is released downwards.Second coil 42 power-off, the second magnetic field dissipate, the magnetic force of armature 3 and the second buting iron 62 also disappears thereupon, and armature 3 relies on self gravitation to be held against the state of the second buting iron 62, thus the state making push rod 2 keep as shown in Figure 4.

First coil 41 is energized, and produces the first magnetic field.Armature 3 and the first buting iron 61 are magnetized, and produce relative magnetic pole.Armature 3 moves up under the attraction of the first buting iron 61, and drives push rod 2 to move up.In the process that armature 3 moves up, stoped at assigned address (as shown in Figure 3) by the first buting iron 61, push rod 2 resets.First coil 41 power-off, the first magnetic field dissipate, the magnetic force of armature 3 and the first buting iron 61 also disappears thereupon, and armature 3, under the attraction effect of permanent magnet 7, is held against the state of the first buting iron 61, thus the state making push rod 2 keep as shown in Figure 3.

Yoke 5 can play the effect of magnetic conduction, increases main magnetic flux, thus increases electromagnetic force.

Upper and lower in the present embodiment is all reference with Fig. 1, more clearly describes the relative concept that the utility model uses, does not form the restriction to right.

Embodiment in the utility model, only for being described the utility model, does not form the restriction to right, other equivalent in fact substituting, all in the utility model protection range that those skilled in that art can expect.
