Amorphous alloy transformer core forming template and forming device

Abstract

The invention discloses an amorphous alloy transformer core forming template and forming device which are used for manufacturing an iron core. The iron core comprises a window. The forming template comprises a substrate and a limiting strip, wherein the transverse length of the substrate is equal to the width of the window, the limiting strip is longitudinally arranged on the substrate, and a gap is formed between the limiting strip and the longitudinal edge of the substrate. By the adoption of the template, the weight of the template can be reduced, the material utilization rate is improved, multiple templates can be used for splicing to form templates of various sizes temporarily, the template purchase cost can be reduced correspondingly, and operation is easy and convenient, so that the size of the template is changed, the template can be used for iron cores of any sizes, the material purchase cost is saved, meanwhile, the production schedule can be accelerated, and production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of transformers, and in particular to an amorphous alloy transformer core forming template and a forming device. Background technique [0002] In the process of producing amorphous alloy transformer core, it must go through processes such as strip cutting, core forming, heat treatment and surface coating. The steps of each process are interlocking, and each step has a great impact on the performance of the core. key role. [0003] At present, amorphous alloy transformer cores are generally rolled from amorphous alloy strips with three bandwidths (142mm, 170mm, 213mm), and the shape of the window is rectangular, such as Figure 1A As shown, the amorphous alloy iron core 100 includes a window 110, the window height A, the window width B, the iron core stack thickness C, and the iron core height is D (that is, strip width+coating thickness), such as Figure 1B shown. During the forming process of the iron cor...

Problems solved by technology

[0005] In view of this, the present invention aims to solve the problem that in the prior art, the overall weight of the molded iron core plus the weight of the template increases, which increases the difficulty of handling the iron core, consumes time and labor, and affects the production progress of the iron core. Increased the cost of the formwork, delaying the production schedule, amorphous alloy transformer core forming formwork, fixed size, heavy weight, poor adaptability and other technical problems
