Moulding process of diagonal end ring of transformer and special mould

Abstract

The invention relates to a moulding process of a diagonal end ring of a transformer and a special mould, belonging to the technical field of the transformers. The technical scheme provided by the invention is as follows: the special mould comprises a bracket (1), a round disk (2), an adjusting mechanism and a rotating mechanism (4); the adjusting mechanism is composed of fixing plates (5), telescopic plates (3), iron support strips (6) and calibrated scales; the telescopic plates are disposed on the fixing plates, the iron support strips are vertically disposed on the telescopic plates and the calibrated scales are disposed on the fixing plates; the round disk is disposed on the bracket via the rotating mechanism; a plurality of circular holes are formed in the round disk and equally separated into 24 groups along the circumferential direction; one fixing plate is fixed by means of each group of circular holes. The invention has the positive effects that a paper board is directly encircled on the special mould by an operator and then a packet tightener is mounted so that the dislocation of the packet tightener is very easy to find out, and the operation safety is effectively improved; the special mould can be further directly rotated when being used, so that the labour intensity of the operator can be relieved; the dimension of the special mould can be adjusted, and the manufactured diagonal end ring better meets the demand of graph paper.

Description

technical field [0001] The invention relates to a forming process of a transformer oblique end ring and a special mold, belonging to the technical field of transformers. Background technique [0002] BACKGROUND OF THE INVENTION When making the oblique end ring of a transformer, the cardboard is brushed with glue and wrapped around an iron mold and tightened with a wrapper. With the continuous increase of the product voltage level and capacity, the diameter of the oblique end ring becomes larger and larger, and the flat It is particularly difficult to wrap the lying type on the iron mold; and because the cardboard is trapezoidal, it is easy to disengage the wrapping device, which has potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a transformer inclined end ring forming process and a special mold, which is easy to operate, improves efficiency, and can easily find out whether the wrapper is misplaced, can effect...
