Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1 ~ 2, the stacked iron core of a kind of solid transformer of the present utility model, its structure is made up of three stem stems 1 and six cross-bridges 2; Three stem stems 1 are parallel and vertically arrange, and the axle center of stem stem and three stem stem axes intersect center lines form three planes and are mutually 120 ° of angles, connect between the top of two often adjacent stem stems and bottom respectively by a cross-bridges.
As shown in Fig. 3 a ~ 3d, Fig. 4 a ~ 4d, shown in, stem stem 1 is formed by stacking by multiple stem stem metal monoliths 3, and stem stem metal monoliths 3 is rectangle, and a minor face of rectangle extends to form inserted terminal, and another minor face is flush end.This inserted terminal can be triangle, circle etc., the angle of inserted terminal can be between 45 ° to 90 °, be good with 90 °, convenient identical with the gap 5 of the metal monoliths of cross-bridges, and it is maximum with the contact area between adjacent sheet, be of value to passing through of the magnetic line of force, but also be conducive to the fixing of position each other, not easily depart from.
Stem stem 1 is alternately superimposed successively downwards, upwards by the flush end of stem stem metal monoliths 3, fixed by fixture or alternate manner; After being fixed together, the flush end of stem stem metal monoliths, the end face of inserted terminal replace the end face of adjacent formation stem stem successively.This end face can be circular, rectangle or approximate ellipsoidal, can by metal monoliths by specification size composition monolithic cell, metal monoliths size in a monolithic cell is identical with thickness, in the metal monoliths forming stem stem, middle several monolithic cell sizes are identical, and the monolithic cell of both sides can successively decrease successively by monolithic flush end size dimension, that is the monolithic cell end face length in the middle of becomes to successively decrease gradually to the monolithic cell end face length of both sides, constitute end face for circular, rectangle or seemingly oval, and this circle, rectangle or the seemingly center of ellipse end face and the circle of other two stem stems, the line at rectangle or seemingly ellipse end face center forms 60 ° of angles, line forms equilateral triangle.
Cross-bridges 2 is formed by stacking by multiple cross-bridges metal monoliths 4, and cross-bridges metal monoliths is rectangle, be provided with gap, and can there be chamfering or fillet in the angle on another long limit with the long limit of stem stem end contact.A lot of material can be saved like this and not affect the electrical characteristic of iron core.
As shown in Fig. 5 a ~ 5d, stem stem becomes equilateral triangle shaped position to place, therefore form three corresponding metal monoliths planes of stem stem and be also mutually 120 °, so two stem stems will be connected, need by cross-bridges metal monoliths two ends bending 60 °, make the body part of dogleg section and non-bending form 120 ° of angles, the dogleg section at such two ends is positioned at same plane with corresponding stem stem metal monoliths respectively and gap contacts connection in consistent manner with inserted terminal.In addition, the length of side of dogleg section is more than or equal to the flush end length of stem stem metal monoliths, and ensure that dogleg section can contact with stem stem metal monoliths is seamless completely like this, gap is also in dogleg section.
When forming cross-bridges 2, positive and negative alternately the superposition successively of cross-bridges metal monoliths 4 forms cross-bridges, the gap 5 of cross-bridges metal monoliths 4 is contacted with the inserted terminal of stem stem metal monoliths 3 connect, and cross-bridges metal monoliths 4 has the long limit of gap 5 to contact with the flush end of the metal monoliths of another stem stem connects.
As shown in Fig. 1 ~ 2, when stem stem metal monoliths is successively decreased to both sides by centre successively according to the size of metal monoliths unit, so several cross-bridges metal monoliths also can form cross-bridges monolithic cell, the monolithic cell namely in cross-bridges or single-sheet thickness equal with the stem stem monolithic cell that corresponding contact connects or stem stem single-sheet thickness.The long limit of cross-bridges and dogleg section length are all that the flush end length of following stem stem monolithic is successively decreased gradually.Meanwhile, the monolithic width of cross-bridges also can be made to successively decrease gradually side from inside to outside, and the outer surface of such cross-bridges can form curved surface, is conducive to saving material and not affecting logical magnetic.
Metal monoliths for forming stem stem and cross-bridges can adopt silicon steel sheet, maintains the opering characteristic of electric apparatus of solid transformer iron core.
A kind of manufacturing process of stacked iron core of solid transformer is as follows:
1) by the flush end of stem stem metal monoliths, alternately superposition forms stem stem successively downwards, upwards, fixes bottom three stem stems make stem stem end face center be mutually 120 ° of angles with fixture or mould etc.;
2) on stem stem end face upwards, successively by positive and negative for multiple cross-bridges metal monoliths successively alternately superposition be placed on corresponding stem stem metal monoliths, the gap of each cross-bridges metal monoliths contacts with the inserted terminal of corresponding stem stem metal monoliths and connects, and the length of side with gap contacts without the flush end of the side of the gap stem stem metal monoliths corresponding with another stem stem and connects; Last like this stem stem metal monoliths inserted terminal contacts completely with next the unilateral of cross-bridges metal monoliths, the unilateral of cross-bridges metal monoliths just constituting the positive and negative of inserted terminal adjacent with front and back respectively contacts and clamps, cross-bridges metal monoliths is all had to clamp between the inserted terminal of multiple stem stem metal monoliths, this contact-making surface is not more conducive to fixing between stem stem and cross-bridges by means of only clamping produces frictional force, and make magnetic circuit more unobstructed, magnetic resistance is little, good electric property.
Aforesaid operations makes multiple cross-bridges metal monoliths define cross-bridges, makes the gap of each cross-bridges metal monoliths contact connection completely with the inserted terminal of corresponding stem stem metal monoliths, namely completes the connection of a cross-bridges and adjacent two stem stems;
3) step 2 is repeated), until complete the connection of three cross-bridges and three stem stem end faces;
4) three stem stems are overturn, make three cross-bridges be positioned at below, after three of well in advance coils are inserted in three stem stems respectively, repeat step 2) ~ step 3), complete between three stem stems and six cross-bridges connection like this, achieve the craftwork manufacture of vertical transformer stacked iron core.
