Abstract

The invention relates to an oblate coiling aluminum die. The oblate coiling aluminum die comprises a semicylindrical semi-blade core die; a core bar is arranged in the middle of the semi-blade core die; two inclined bars are arranged on the middle plane of the semi-blade core die along the direction of an axial line; the semi-blade core die is a semicylindrical shell; grooves for accommodating the core bars are formed on middle shafts of both ends of the semi-blade core die; the inclined bars are arranged at the edge of the semi-blade core die; and the inclined sides of the inclined bars are arranged to the same direction. The aluminum die assembled by three parts has a simple structure and is relatively portable; furthermore, the production technical requirement and the production cost are reduced; the aluminum die cannot be deformed, so the quality is guaranteed; and the aluminum die can be used forever.

Description

A kind of oblate coiling aluminum dipping form

Technical field

The present invention relates to the used mould of a kind of transformer coiling, especially relate to a kind of oblateness coiling aluminum dipping form that can overcome use wooden model defective.

Background technology

At present, because the demand on the market, each producer is more and more higher to the requirement of transformer production, and each link is all in constantly upgrading improvement for this reason, and some equipment in past, technology etc. may be significantly not enough.Just as transformer coiling, what used in the past is the wooden model coiling always, light because of its cost is lower, but open defect is arranged, and promptly the wooden model easy deformation can't guarantee the quality that winds the line, and can only use one to twice.

Summary of the invention

Technical problem to be solved by this invention provides a kind of distortion and can be nonexpondable oblate coiling aluminum dipping form of being not easy.

The present invention solves the technical scheme that its technical problem takes: a kind of oblate coiling aluminum dipping form, comprise semi-cylindrical half a lobe core, and be provided with the core bar in the centre of half lobe core, be provided with two slanted bars in half lobe core mid-plane along axis direction.

In order to alleviate the weight of this aluminum dipping form, described half lobe core is a semi-cylindrical shell, respectively is provided with the groove of placing the core bar in jack shaft position, half lobe core two ends.

For convenience aluminum dipping form is pulled down, described slanted bar is installed on the edge of half lobe core, and hypotenuse is installed in the same way.

The invention has the beneficial effects as follows: be divided into the aluminum dipping form that three parts combine, simple in structure, light relatively, reduced manufacturing requirements, reduced production cost, it is indeformable that aluminum dipping form has also reached, and guaranteed quality, also can forever use.

Fig. 2 is the right view that the present invention assembles schematic diagram;

Fig. 3 is the cutaway view of the present invention's half lobe core.

Among the figure: 1, slanted bar 2, core bar 3, half lobe core 4, circular cylindrical shell 5, groove

Embodiment

A kind of as depicted in figs. 1 and 2 oblate coiling aluminum dipping form comprises semi-cylindrical half a lobe core 3, is provided with core bar 2 in the centre of half lobe core 3, is provided with two slanted bars 1 in half lobe core, 3 mid-planes along axis direction.Described slanted bar 1 is installed on the edge of half lobe core 3, and hypotenuse is installed in the same way.

Half lobe core is a half-cylindrical shell 4 as shown in Figure 3, respectively is provided with the groove 5 of placing core bar 2 in jack shaft position, half lobe core, 3 two ends.

In production and use, water according to size earlier and outpour three kinds of parts, handle through operations such as cutting, polishing, polishings respectively again.With bolt this part is linked up respectively at last, be used, make it be formed with the oblate aluminum dipping form that two parts combine by two identical aluminum dipping forms.This mould is fairly simple in process of production, and simple three parts combine, and one has reduced manufacturing requirements, has reduced production cost; Two come aluminum dipping form also to reach indeformable, have guaranteed quality, also can forever use.This mould is installed with wooden model equally convenient and simple in the coiling process, is convenient to beat.
