Abstract

Disclosed is a noise-free electromagnet with large suction force. The utility model is structured that a coil is arranged in the middle of a fixed iron; a T-shaped moving iron whose upper end is connected with the loading spring is inserted in the frame of the coil; the moving iron moves up and down along a slide way at the coil center; a cushion pad is positioned between the moving iron and the fixed iron; a control block consisting of a travel switch and a control circuit is arranged on the upper end of one side of the fixed iron. The utility model has the advantages of low electricity consumption, low noise, large suction, low comprehensive cost, security and reliability; in the utility model a pole end face needs no processing and a short circuit ring is abolished. The electromagnet current is about 90 per cent less than that in the prior art, therefore compared with the existing electromagnet, the utility model can help save electricity by 90 per cent. The suction of the electromagnet is 20 per cent larger than that currently available.

Description

The big noiseless electromagnet of suction

Affiliated technical field

The utility model relates to a kind of electromagnet.

Background technology

Existing alternating electromagnet substantially all is as permeability magnetic material with silicon steel sheet.It generally is through punch ram, cut out, processing technologys such as stack, riveted, and in order to reduce noise and the reliable adhesive that electromagnet produces, the magnetic pole end face needs break-in, and short-circuited conducting sleeve is installed.Yet the magnetic pole area dirt of above-mentioned electromagnet is too much, can make the noise of electromagnet excessive, and therefore, the work of electromagnet electric current also increases, and very easily burns electromagnet coil.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of simple in structure, reasonable in design, saves energy, noiseless, the electromagnet that suction is big.

In order to achieve the above object, the technical solution adopted in the utility model is: be provided with coil in the middle of the quiet iron, be inserted with the moving iron of tee T that the upper end links to each other with the load spring in the magazine, moving iron core moves up and down along the slideway at coil center, be equipped with cushion pad between moving iron and the quiet iron, quiet iron one upper lateral part is equipped with the controll block of travel switch and control circuit composition.

The utility model has the advantages that:

Power consumption is low, and noise is little, and suction is big, and the magnetic pole end face need not processed, the cancellation short-circuited conducting sleeve, and integrated cost is low, and is safe and reliable, and this electromagnet current is littler by about 90% than existing electromagnet current, and this electromagnet is compared with existing electromagnet, can economize on electricity about 90%.This electromagnet is inhaled bigger by about 20% than existing electromagnet suction.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the utility model is to be provided with coil 2 in the middle of the quiet iron 1, the moving iron 3 moving iron cores of the tee T that links to each other with load spring 4 on being inserted with in coil 2 frameworks move up and down along the slideway 7 at coil 2 centers, be equipped with cushion pad 8 between moving iron 3 and the quiet iron 1, quiet iron 1 one upper lateral parts are equipped with the controll block 6 of travel switch K5 and control circuit composition.

Described control circuit is by travel switch k5, rectification, continued flow component D ₁, D ₂, D ₃, D ₄With coil L ₁, L ₂, L _{3 (2)}Tap link to each other.Operation principle of the present utility model is:

The moment of the input of the utility model circuit after energized, electric current is by travel switch k, rectifier cell D ₁, actuating coil L ₂, (if when power supply is negative half period, electric current is by rectifier cell D ₂, actuating coil L ₃, travel switch k) at this moment actuating coil then produce electromagnetic force, under the effect of electromagnetic force, moving iron 3 moves downward along slideway, moves iron 3 impact stroke switch k after moving iron 3 moves to certain distance ₅Travel switch k then ₅Normal contact disconnect actuating coil L ₂, or L ₃Dead electricity, then starting process finishes.Meanwhile electric current makes hold-in winding L by rectifier cell ₁Charged and produce electromagnetic force, under the effect of electromagnetic force, make iron 3 continue to move downward, fit like a glove up to moving iron 3 and quiet iron 1, at this moment hold-in winding L ₁Only need less electric energy, just can make electromagnet be in the maintenance operating state.So far electromagnet is finished the overall process of starting and maintenance.When power supply disconnects, hold-in winding L ₁Dead electricity, electromagnetic force disappears, and under the effect of load spring 4, moving iron 3 resets to reset condition.Work so again and again.Since the effect of rectification, continued flow component, hold-in winding L ₁, the electric current that is passed through is an arteries and veins stream, and this moment is living electromagnetic force as long as arteries and veins is miscarried, and greater than the operational forces of electromagnet, electromagnet just can be in running order reliably.Because the arteries and veins stream that passes through of hold-in winding is approximately direct current, thus this electromagnet in working order the time iron core can not adorn short-circuited conducting sleeve, do not have the alternating electromagnetic noise, at hold-in winding L yet ₁In the electric current that passes through compare with the alternating electromagnet of existing same model, the required existing work of electromagnet electric current of current ratio of the utility model is little by 90%, just can produce identical electromagnetic force, so this electromagnet is compared with existing alternating electromagnet, can economize on electricity about 90%, because actuating coil L ₂, L ₃It is charged just to start moment, by design, can realize the moment adhesive of big suction, compare with existing alternating electromagnet, under the identical situation of volume, suction can increase about 20%, impact when reducing adhesive, the utility model does not have cushion pad between moving iron and quiet iron.
