On be additionally provided with the 3rd outer conical surface 17, the 4th outer conical surface 18, with the 4th outer conical surface coordinate spacing seam 19.In first
There is magnetic focusing annular ridge 20 conical cavity and the second inner conical chamber intersection.First magnetic focusing ring is arranged at the first outer conical surface top
Shape ridge 21.There is the second magnetic focusing annular ridge 22 between second outer conical surface and the 3rd outer conical surface.Radius is provided with magnetically conducting inner tube
For 1 millimeter of fillet 23.
As shown in Fig. 2 the coil rack of Combination Welding structure, its top is non-magnetic inner cylinder, and its underpart is magnetically conducting inner tube,
Weld together in lower middle position；Magnetically conducting inner tube directly contacts the lower dead center as armature with armature during original state；
Electromagnet is initially powered up starting to move in this period upwards to armature, is produced on the contact surface 24 of armature and magnetically conducting inner tube downward
The electromagnetic force of armature is pulled to hinder the motion of armature, influence, sets in the edge of magnetically conducting inner tube caused by weaken this electromagnetic force
Put the fillet 23 of 1 millimeter of radius.Power maximum on this contact surface is carried within 2 newton by limitation.Occur around contact surface
One, than stronger magnetic disturbance, reduces the pulling force of contact downwards.
As shown in Fig. 3, Fig. 4, Fig. 5, back-moving spring chamber is stretched out in push rod upper end in yoke.First inner conical chamber taper α 1
For 26 °.Second inner conical chamber taper α 2 is 15 °.Magnetic focusing annular ridge taper α 3 between first and second female cone is 74 °,
There are the rounding 25, rounding 26 that radius is 1 millimeter between this annular ridge and first, second female cone respectively.First magnetic focusing annular ridge
Median ridge depth δ 1 is 2 millimeters, and ridge taper α 4 is 120 °.First outer conical surface taper β 1 is 60 °.Second outer conical surface taper β 2 is
32°.Second magnetic focusing annular ridge median ridge depth δ 2 is 5 millimeters, and ridge taper α 5 is 59 °.At the top of second magnetic focusing annular ridge annular ridge

Gently crossed at 45 millimeters.Armature lower end base, which has, extends to center hole 28 on the upper side in the middle part of armature.Center hole diameter 20
Millimeter, 132 millimeters of depth.
Air gap magnetic is reduced in the case where coil magnetomotive force is certain by the combination of the shapes such as inclined-plane, inclination angle, fillet
Resistance.
Magnetic induction intensity focuses on the magnetic focusing annular ridge of yoke, and is spread to neighbouring air gap, air gap
Magnetic induction intensity show than more uniform umbrella fractions distribution, the push rod convex of non-magnet material limit umbrella form to
Upper development, its umbrella form bottom are merged with the outer conical surface of armature first, make the magnetic focusing annular ridge of yoke, armature first cylindrical
The conical surface, the permeability magnetic material intrinsic inductance distribution of armature the first magnetic focusing annular ridge are roughly the same, at this moment in the first outer cone
The close maximum of electromagnetic force caused by face；Similarly magnetic induction intensity focuses on to yoke on the second magnetic focusing annular ridge of armature
Two inner conical chamber ends are spread, and the second inner conical chamber is showed maximum magnetic induction, due to now the second outer cone
Face and the 3rd outer conical surface are with the distant of the second inner conical chamber therefore in the second outer conical surface and the 3rd outer conical surface
Electromagnetic force is little.
When about 0.1 second electromagnetic force used time for reaching 0.075 ampere-hour and producing about 27 newton of the electric current by coil, this moment
Electromagnetic force is suitable with the gross weight of armature, and armature is in critical operating state.
In maximum 0.466 ampere-hour of the maximum 25.4 millimeters of electric currents of air gap, there is the newton of EIAJ 357, now held in the mouth in electromagnet
The electromagnetic force of iron is mainly produced by the first magnetic focusing annular ridge, the first outer conical surface, is gone out at the top of the first magnetic focusing annular ridge
EIAJ in existing unit area.
First outer conical surface of armature is distant apart from yoke magnetic focusing annular ridge, and the magnetic induction of the first outer conical surface is strong
Degree declines, and the second outer conical surface, the 3rd outer conical surface and the second magnetic focusing annular ridge subtract apart from yoke magnetic focusing annular ridge distance
Small magnetic induction intensity rises.When maximum 0.466 ampere-hour of the minimum 0 millimeter of electric current of air gap, there is the newton of EIAJ 548 in electromagnet,
Now the output of electromagnet is produced by the second outer conical surface, the 3rd outer conical surface and the second magnetic focusing annular ridge, is gathered in the second magnetic
Occurs the EIAJ in unit area at the top of burnt annular ridge.
Referring to Fig. 3, Fig. 4, the twice magnetic focusing ring on armature participates in magnetic focusing successively in armature motion overall process, is expert at
Electromagnetic force is mainly provided by the first magnetic focusing ring and the first outer conical surface during 0 millimeter of journey, in the constantly upward motion process of armature
The magnetic induction intensity of first magnetic focusing ring is gradually reduced and the magnetic induction intensity of the second magnetic focusing ring gradually increases, when stroke 25.4
The magnetic induction intensity of the second magnetic focusing ring reaches maximum during millimeter, and now electromagnetic force is mainly by the second magnetic focusing annular ridge, second
Outer conical surface and the 3rd outer conical surface provide；Under conditions of the driving of same 0.466 wire arrangement loop current, the electromagnetic force change of armature
About 200 newton, change is more steady, takes full advantage of permeability magnetic material permeance itself.
The lower end of armature sets angled different twice chamfering, and this twice chamfering gently crosses at 45 millimeters of diameter,
Purpose be allow from coil rack lower baffle enter magnetic power more smooth out armature is entered by coil rack magnetically conducting inner tube.
Center hole can improve the magnetic induction intensity of armature while can also mitigate armature weight, reduce the response time after being powered.
Above-described embodiment is that the above of the present utility model is described further, but this should not be interpreted as into this practicality
The scope of new above-mentioned theme is only limitted to above-described embodiment.It is all that the utility model is belonged to based on the technology that the above is realized
Protection domain.
