Description
Technical field:
The present invention relates to electromagnetic mechanism technical field, be specifically related to a kind of high speed long-life electromagnetic machine
Structure.
Background technology:
Existing electromagnetic mechanism is all to utilize coil electricity to make upper and lower iron core close, in order to keep closing
Closing, solenoid the most in the energized state, so not only reduces the use of solenoid
In the life-span, the temperature of solenoid is always held at higher level, causes the aging speed of solenoid
Degree is exceedingly fast, and has had a strong impact on adhesive dynamics and the closing speed of electric magnet.Therefore electromagnetic contactor
Iron coil burn observations is the most more typically.
Have again be exactly iron core in closing course, the resistance of back-moving spring to be overcome, thus make
Having become the reduction of iron core closure speed, when in use, catalyst is typically long-term at closed form
Under state, damping spring, tripping spring is caused to be in for a long time under energy storage state.By the physics of spring
Characteristic, it can be deduced that catalyst is after running a period of time, and the time of its opening velocity is upper and anti-
Only in the performance of Guan Bi spring worse and worse.So, often there will be catalyst point/close negative
During load contact burnt/burn.The coil blackout when release, automatically resets by back-moving spring, disconnected
Open speed to be substantially reduced, the most easily produce contact arc discharge phenomenon, so make the life-span of upper and lower contact
It is greatly reduced.
Also having a kind of energy-saving electrical magnetic mechanism to be usually magnetic to keep, this kind of electromagnetic mechanism is that coil adds
Electricity, keeps attracting state, the coil blackout when hold mode, and in low-power consumption by permanent magnet
Run in the case of electricity consumption.In attracting process, the resistance of back-moving spring to be overcome, reduces
The closure speed of iron core, makes contact be easily generated phenomenon of arc discharge in closing course equally, makes up and down
The life-span of contact is greatly reduced.
Summary of the invention:
It is an object of the invention to provide a kind of high speed long-life electromagnetic mechanism, it can solve existing electricity
Magnetic mechanism energy consumption iron core high, upper and lower closes and opening velocity is slow, upper and lower contact easily burns, up and down
The problem of the easy arcing in contact.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions:
It comprises dynamic ram, upper shell, dynamic iron core, dynamic iron core fixed installation plate, static iron core, coil,

Rod hinge connection slides and is fixed on the inside of self-locking mechanism shell, the hinged fixing peace of self-locking active pull rod
Being contained in the inside of self-locking mechanism shell, the reset that is mounted below of self-locking active pull rod stretches bullet
Spring, keeps one end of the external movable rod of electric magnet be hinged with slide link and keep electric magnet to move
Make core bar；Mounting coil is fixed on static iron core；Dynamic iron core fixed installation sleeve-board is contained in dynamic iron core
And be fixed on together on dynamic ram, self-locking connects core bar and is fixed on dynamic iron core and is sleeved on self-locking
Inside mechanism shell；Upper reset push rod is fixed on dynamic ram, and upper reset driving lever is hingedly fixed in
On upper shell, upper boosting spring core rod is sleeved on upper shell, and upper boosting spring housing is contained in and helps
Pushing away on spring core rod, one end of upper boosting spring is attached to the bottom of boosting spring core rod, above help
The other end pushing away spring is attached to the inside of upper shell；Upper self-locking knocker is fixed by upper self-lock switch
Pressing plate is fixed on upper shell；One end suit of back-moving spring is fixed on the inside of lower house, multiple
The other end suit of position spring is fixed on below dynamic iron core fixed installation plate；Lower reset driving lever
Being hingedly fixed on lower house, lower reset push rod is fixed on dynamic ram；Lower self-locking knocker passes through
Lower self-lock switch fixation clip is fixed on lower house, and lower boosting spring housing is contained in lower boosting spring
On core bar, one end of lower boosting spring is attached to above lower boosting spring core rod, lower boosting spring
The other end be attached to below lower house.
The principle of the invention is as follows:
(1) add the boosting spring of a drag effect in the past, accelerate the Guan Bi speed of iron core
Degree；
(2) under, boosting spring is when iron core closes, owing to iron core closing face is less than lower boosting bullet
The self-locking of spring keeps plane, and so in closing course, lower boosting spring serves again buffering work
With.
(3) upper boosting spring is when iron core disconnects, and keeps plane less than upper owing to iron core disconnects
The self-locking of boosting spring keeps plane, so during disconnecting on boosting spring also play slow
Punching effect.
(4) in attracting process, coil energization due to apart from big causation in dynamic iron core
Magnetic force can be little, initial velocity can be low, by increasing the thrust of upper boosting spring, makes iron core add
Speed is run downwards, and in descending mistake two/for the moment, the magnetic force of dynamic iron core effect is all the more got over by coil
Greatly, adding the inertia of operation, the downstream rate of dynamic iron core is the most drastically accelerated, and makes iron core with quiet
Iron core accelerates Guan Bi, has stopped upper and lower contact phenomenon of arc discharge, has added the service life of contact.
(5) during disconnecting, the release rapidly of back-moving spring adds pushing away of upper and lower boosting spring
Power, makes that iron core is very fast to be run up, and separates with static iron core rapidly, stops upper and lower contact arcing
The generation of phenomenon, adds the service life of contact equally.
(6) when the unexpected power-off of electrical network, maintaining body can automatically open up, and makes iron core rapid
Separate with static iron core, make this device be truly realized the condition of safe operation.
