Abstract
The utility model relates to a rectangular winding die of a transformer. The rectangular winding die comprises side plates with square holes, a left framework and a right framework, wherein the left framework and the right framework are respectively rolled into side waists with arc-shaped sides, the upper edges and the lower edges of the steel plates are parallel and are tangent to the arc-shaped side waists, seal plates are respectively arranged on the sides of the two ends of the left framework and the right framework, the left framework corresponds to the right framework, and a spacing is formed between the left framework and the right framework; threaded holes are formed in the seal plates, through holes are formed in the corresponding side plates, and bolts pass through the through holes of the side plates and the threaded hole to fix the left framework and the right framework. The rectangular winding die has the advantages of the reasonable structure, strong rigidity, high geometric accuracy, simplicity in operation, long service life, and the like, and has higher popularization and application value.
Description
Technical field
The utility model belongs to transformer technology field, especially relates to a kind of transformer winding former.
Background technology
For reducing the size of transformer, the distance between iron core, adopts square coil conventionally.Therefore rectangle winding former is also widely used.Conventionally adopt wooden model at the distribution transformer winding former that does not need cardboard cylinder to make the miniature transformer of skeleton, by two sphenoids and and form, be stuck with axle thick stick by the baffle plate at two ends.When coiling, conventionally at the cable paper of the external diameter pad 0.5mm of mould, be mainly convenient operation and do not injure coil inner surface while considering withdrawing pattern.Adopt the mould of said structure, because wooden model is using easily damaged, after using repeatedly, the precise decreasing of its mould, causes the coil dimension of coiling to occur deviation.Relatively complicated in the time of dismounting mould in addition, bring trouble to coiling work, affect production efficiency.
Utility model content
The purpose of this utility model is the problems referred to above for prior art, and a kind of transformer rectangle winding former is provided, long service life, and geometric accuracy is high, and production efficiency is high.
For achieving the above object, the utility model has adopted following technical scheme to be:
A kind of transformer rectangle winding former, it is characterized in that comprising side plate and left and right skeleton with square hole, it is circular arc side waist that left and right skeleton is made sidepiece by roll of steel plate respectively, parallel below on its steel plate, and tangent with circular arc side waist, the sidepiece at skeleton two ends, left and right is respectively equipped with shrouding, left and right skeleton is corresponding, between the skeleton of left and right, is provided with spacing, and shrouding is provided with screwed hole, corresponding side plate is provided with perforation, passes through perforation and the fixing left and right of the screwed hole skeleton of side plate with bolt.
When use,, be then arranged on coil winding machine by the square hole of side plate with square steel axle, just can realize the coiling of coil.After coiling completes, can with crane, coil be hung together with mould to coil winding machine, then draw off bolt with spanner, biside plate separates left and right skeleton, owing to being provided with spacing between the skeleton of left and right, is just very easy to the demoulding.Owing to adopting the winding former of steel, its precision is high, is not easy distortion, has greatly improved the useful life of winding former, and has been convenient in demoulding.
When concrete use, the side waist of one of them skeleton in the skeleton of left and right is provided with straight board lath, and straight board lath two ends exceed the two ends of skeleton main body.The effect of straight board lath is the fixing of wire terminal block, facilitates the coiling of coil.
When concrete use, shrouding is provided with location hole, and corresponding side plate is provided with locating pin.By location hole and locating pin, further ensure the installation accuracy of winding former.
The beneficial effects of the utility model are: the advantage such as the utility model is rational in infrastructure, rigidity is strong, geometric accuracy is high, simple to operate, long service life, has higher popularizing value.
Brief description of the drawings
Below in conjunction with drawings and Examples, utility model is further illustrated.
Fig. 1 is the profile schematic diagram of the utility model embodiment.
Fig. 2 is the mounting structure schematic diagram of the utility model embodiment.
In figure: 1, left skeleton 2, right skeleton 3, side plate 4, square hole 5, shrouding 6, straight board lath 7, bolt 8, perforation 9, screwed hole 10, locating pin 11, location hole 12, side waist.
Embodiment
In Fig. 1 and Fig. 2, a kind of transformer rectangle winding former, comprise the side plate 3 with square hole 4, left skeleton 1 and right skeleton 2, it is circular arc side waist 12 that left skeleton 1 and right skeleton 2 are made sidepiece by roll of steel plate respectively, parallel below on its steel plate, and tangent with circular arc side waist 12, the sidepiece at left skeleton 1 and right skeleton 2 two ends is respectively equipped with shrouding 5, left skeleton 1 and right skeleton 2 are corresponding, between left skeleton 1 and right skeleton 2, be provided with spacing, shrouding 5 is provided with screwed hole 9, corresponding side plate 3 is provided with perforation 8, shrouding 5 is provided with location hole 11, corresponding side plate 3 is provided with locating pin 10, pass through perforation 8 and the screwed hole 9 fixing left and right skeletons of side plate 3 with bolt 7, by location hole 11 and locating pin 10, further ensure the installation accuracy of winding former.12, the side waist of left skeleton 1 is provided with straight board lath 6, and 6 two ends of straight plate exceed the two ends of left skeleton 1 main body.The effect of straight board lath 12 is the fixing of wire terminal block, facilitates the coiling of coil.
When use,, be then arranged on coil winding machine by the square hole 4 of side plate 3 with square steel axle, just can realize the coiling of coil.After coiling completes, can with crane, coil be hung together with mould to coil winding machine, then draw off bolt 7 with spanner, biside plate 3 separates left skeleton 1 and right skeleton 2, owing to being provided with spacing between left skeleton 1 and right skeleton 2, is just very easy to the demoulding.Owing to adopting the winding former of steel, its precision is high, is not easy distortion, has greatly improved the useful life of winding former, and has been convenient in demoulding.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection range of the present utility model.
