Abstract

The utility model relates to a cake-typed silicon steel sheet magnetic permeable iron core, which comprises a highly magnetic permeable silicon steel sheet material and a pull rod of a locking sheet material. Each sheet material is provided with a through hole at the center; the pull rod positioned in the through hole is sheathed with an insulating pipe. Key points of the cake-typed silicon steel sheet magnetic permeable iron core are that: each end of the pull rod is provided with a vertical clamping sheet that is fixedly connected in a welding way; an insulating sheet is arranged between the clamping sheet and the silicon steel sheet material. Instead of adopting crews and nuts to connect, lock and fix the silicon steel sheet material in the prior art, the utility model adopts the proposal of welding to arrange the clamping sheet, thus avoiding the defect that the diameter and the length of the screws need to be increased in light of the strength of screw threads, relatively shortening diameter of the pull rod and realizing the goal of increasing magnetic permeable section by reducing aperture of the central hole of the silicon steel sheet material. After the pull rod and the clamping sheet structure are adopted, the outer surface of the clamping sheet material levels off; therefore, diameter of a coil can be reduced, copper consumption is decreased and the gap between the coil and the sheet material is also eliminated, thereby realizing the purposed of compact structure and small noise.

Technical field
The utility model belongs to a kind of cake formula silicon steel sheet conducting magnet core.
Technical background
The conducting magnet core of band air gap cake formula grounding transformer, reactor, silicon steel sheet, can satisfy the desired value of inductance value by the air gap between adjusting iron core stem stem, the iron core cake, for this reason, the iron core stem stem must have a plurality of iron core cakes to be stacked into the iron core stem stem, the folder of wherein still needing fills up the air gap of insulator, the iron core segmentation, clamping, the fixation problem that run into thus influence the ageing of such reliability of products and operation always.
Traditional cake formula silicon steel sheet conducting magnet core has screw rod clamped-in style and bandage to clamp two kinds of structures of resin solidification formula.Fig. 1 is a screw rod clamped-in style iron core schematic diagram, when making, subpunch shears the high magnetic conduction silicon steel sheet sheet stock 1 of certain specification size, and a through hole is offered at the middle part of every sheet stock 1 again, screw rod 2 passes through hole with all sheet stock 1 strings together, with making sheet stock stacked fastening after the locking of two nuts, 3,4 two.There are the following problems to utilize the iron core that this mode makes: 1, because screw rod 2, nut are influenced by the screw strength of nut 3 when locking, generally need select the screw rod of thick diameter for use, cause through hole will open more greatly, add to taking the insulation between screw rod and through hole into account, need again to open through hole bigger, so that be nested with insulated tube in screw rod 2 peripheries, its result causes the iron core magnetic conduction cross section of certain area to reduce, if remedy the magnetic conduction cross section that loses because of perforate, just must increase iron core diameter and satisfy, thereby take material.2, because the very long outer naked screw rod of the peripheral existence of iron core, when making product, coil can not be close to iron core, not only cause the invalid increase of internal coil diameter, consumptive material is big, and nut 3 is by artificial locking, elasticity is difficult to unanimity, in service often to occur electric and magnetic oscillation sound easily excessive in energising for product, the phenomenon that noise is excessive, both uneconomical also contaminated environment.
For bandage resin solidification formula iron core, select for use and do not have the pattern that the dimension glass tape carries out colligation, resin solidification, during making, carry out predry earlier and make an uproar, be cured with resin behind iron core and closed assembly, dry again, colligation is not further carried out dried making an uproar after having the dimension band more then, complex process, difficulty is big, and often finishing iron core needs through dried making an uproar repeatedly, and operational sequence is many, and wrap the nothing dimension in the iron core periphery and be with, increase has increased the internal diameter size of dead coil too with the iron core external diameter, the loss copper material.Do not have the dimension band because one deck has been wrapped up in the iron core periphery, both be unfavorable for the iron core heat radiation, and iron core is under long electric and magnetic oscillation power effect, resin bed easily goes to pot, and causes producing air gap between the iron core sheet stock, and noise changes with the length of timeliness, directly causing bandage gets loose and burns product, poor reliability.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of structure novel cake formula silicon steel sheet conducting magnet core, this product with compact structure, easy to assembly, and effectively the magnetic conduction cross section is big; Coil can be close to the iron core installation during making, helps reducing the product noise thereby reduce the space.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this cake formula silicon steel sheet conducting magnet core, the pull bar that comprises high magnetic conduction silicon steel sheet sheet stock, locking sheet stock, the middle part of every sheet stock is provided with a through hole, be positioned on the pull bar of through hole and be with insulated tube, its main points are: the both ends of pull bar respectively are provided with one and vertically are the clamp clip that the welding shape is fixedly connected, and are provided with insulating trip between clamp clip and the silicon steel sheet sheet stock.
Beneficial effect: the utility model adopts screw rod and nut to connect the silicon steel sheet sheet stock that is locked by changing original technology, and adopt welded type that the scheme of clamp clip is set, avoided considering screw strength and increased the defective of screw diameter, length because of needs, make the diameter of pull bar to reduce relatively, reach the purpose that reduces silicon steel sheet sheet stock middle part through-hole aperture and increase the magnetic conduction cross section.After adopting pull bar and clamp clip structure, the clamp clip outer surface is flat, and therefore, coil both can reduce diameter, reduces the copper material consumption, can avoid again the space occurring between coil and the sheet stock, thereby realize compact conformation, reduce the purpose of noise.
Be the utility model content that further sharpens understanding, also the utility model is described in further detail in conjunction with the accompanying drawings below by embodiment.
Description of drawings
Fig. 1 is the product structure schematic perspective view of prior art.
Fig. 2 is the perspective view of an embodiment of the utility model.
Sequence number is represented respectively among the figure: silicon steel sheet sheet stock 1, screw rod 2, nut 3,4, clamp clip 5.
Embodiment
Referring to Fig. 2.The structure of present embodiment is compared with prior art products, and structures such as the shape of silicon steel sheet sheet stock 1 and the through hole at middle part, insulated tube are consistent fully, do not need to make change.Just set up two clamp clips 5, be provided with insulating trip between clamp clip 5 and the outermost sheet stock 1 in the axial both sides of original pull bar.
Installation process is as follows, earlier a slice clamp clip is welded in pull bar (existing product is an a screw rod) end admittedly, then, silicon steel sheet sheet stock 1 through hole (a kind of fabrication hole) is inserted in pull bar successively, again stacked good iron core is moved on the special pressure machine and compress iron core, make the other end of pull bar pass another clamp clip middle part through hole, install by the special warfare welding again.The iron core made of method has pressure and equates lamination progression unanimity according to this.Thereby guarantee that the uniformity of design load, the close cross section of design magnetic value need not to increase any invalid size, guarantee the minimum value of internal coil diameter, reduce the loss of coil copper material, because pull bar (welding bars) has enough pulling force, behind the pressure welding location, brush antirust paint and get final product, permanent one, guarantee not to be subjected to timeliness to influence, greatly reduce labor strength, and it is minimum that noise is reduced to.
This product can be selected the punching through-hole aperture according to iron core diameter, this aperture can be decided according to the pulling force of magnetic conduction steel not, the pull bar of diameter phi 4,2.62 tons of pulling force are arranged, because of not considering screw strength, the clamping force that directly this pulling force is used for lamination, thus through-hole diameter on the silicon steel sheet sheet stock 1 can be reduced greatly, and in general the fabrication hole of φ 4-φ 10 can satisfy clamping force.After silicon steel sheet sheet stock through-hole diameter is less than the certain proportion scope, almost just do not influence its magnetic conduction efficient.
