Problems solved by technology

Just like transformer winding, wooden mold winding has been used in the past, because of its low cost and light weight, but it has obvious defects, that is, the wooden mold is easy to deform, the quality of winding cannot be guaranteed, and it can only be used once or twice.

Embodiment Construction

[0012] Such as figure 1 and figure 2 An oblate winding aluminum mold is shown, including a semi-cylindrical half-petal mandrel 3, a core strip 2 is arranged in the middle of the half-petal mandrel 3, and the middle plane of the half-petal mandrel 3 is along the axial direction Two oblique bars 1 are provided. The inclined strip 1 is installed on the edge of the half-valve mandrel 3, and the inclined sides are installed in the same direction.

[0013] Such as image 3 The half-petal mandrel shown is a semi-cylindrical shell 4, and grooves 5 for placing core strips 2 are respectively provided at the positions of the middle axes at both ends of the half-petal mandrel 3.

[0014] In the process of production and use, three kinds of parts are first poured according to the size, and then processed by cutting, grinding, polishing and other processes respectively. Finally, these parts are connected with bolts, and two identical aluminum molds are used together to form a flat roun...

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

technical field [0001] The invention relates to a mold used for transformer winding, in particular to an oblate winding aluminum mold capable of overcoming the defects of using wooden molds. Background technique [0002] At present, due to the demand in the market, various manufacturers have higher and higher requirements for transformer production. For this reason, every link is constantly upgrading and improving. Some equipment and technologies in the past may be obviously insufficient. Just like transformer winding, wooden mold winding has been used in the past because of its low cost and light weight, but it has obvious defects, that is, the wooden mold is easy to deform, the quality of winding cannot be guaranteed, and it can only be used once or twice. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oblate winding aluminum mold that is not easily deformed and can be used many times. [0004] The technic...
