Automatic iron core stacking production line for marine transformer manufacturing

Abstract

The invention relates to the technical field of marine transformer manufacturing and processing, in particular to an automatic iron core stacking production line for marine transformer manufacturing. The production line comprises a stacking table, two guide devices and a stacking device, the two guide device which are symmetrical left and right are arranged in the upper end of the stacking table, and the stacking device is arranged in the middle of the stacking table and located between the two guiding devices. According to the iron core stacking device, the function of stacking silicon steel sheets of iron cores of the same shape and different specifications can be achieved by replacing placing plates and stacking frames of different specifications, meanwhile, the silicon steel sheets can be alternately stacked left and right through the two guiding devices, and therefore the iron core stacking efficiency can be improved; and scale strips are arranged on connecting plates, so that the descending height of the concentric-square-shaped frame during stacking of the silicon steel sheets can be observed conveniently, the height difference is the stacking thickness of the iron core, and whether the stacking number of the silicon steel sheets is accurate or not can be determined.

Description

technical field [0001] The invention relates to the technical field of manufacturing and processing of marine transformers, in particular to an automatic stacking production line for iron cores used in manufacturing marine transformers. Background technique [0002] Marine transformer is a kind of power equipment used by ships. There are three main cooling methods for transformers: natural cooling or forced air cooling, oil immersion cooling and contact forced cooling. The transformer is mainly composed of iron core, coil, casing or oil tank and insulating bushing. The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheet with high silicon content and coated with insulating paint on the surface. Stacked. The iron core and the coil wound on it form a complete electromagnetic induction system. The transmission power of the power transformer depends on the material and cross-sectional area of ​​the ...

AI Technical Summary

Problems solved by technology

[0003]At present, silicon steel sheets for stacking iron cores are divided into E-type, U-type, C-type and mouth-type according to their shapes. The assembly method of E-type silicon steel sheets has overlapping There are two kinds of stacking method and overlapping method. The overlapping method is to distribute the openings of silicon steel sheets on both sides alternately one by one. The existing marine transformer cores have the following problems in the stacking production process: a. The existing stacking equipment needs manual assistance to record the stacked number of silicon steel sheets when stacking silicon steel sheets, and there are uncertain factors in manual operation, which is prone to core stacking The number of silicon steel sheets is more or less; b. Many existing stacking equipment cannot stack silicon steel sheets for iron cores of the same shape and different specifications, making it less practical
