Dry-type transformer iron core clamping device with automatic alarm function

Abstract

The invention relates to the technical field of iron core manufacturing, and discloses a dry-type transformer iron core clamping device with an automatic alarm function, which comprises a base, a feeding mechanism is movably mounted at the upper end of the base, a mounting block is arranged at the upper end of the right side of the base, and an iron core is clamped and placed in the feeding mechanism; and anti-loosening mechanisms are movably mounted on the front side and the rear side of the feeding mechanism, a notch maintenance mechanism is movably mounted in the mounting block, the feeding mechanism comprises a movable table, each anti-loosening mechanism comprises a telescopic block, and the movable table is in sliding connection with the telescopic block. Through mutual cooperation between the flexible scraper blade and the pressure spring, the flexible scraper blade always keeps contact with the lower edge of the right end of the iron core under the elastic force action of the pressure spring in the moving process of the sliding block body, so that antirust agent liquid drops gathered on the lower surface of the iron core can be automatically scraped off, and the service life of the iron core is prolonged. And damage to the insulating layer caused by long-time contact between the rust agent and the insulating layer on the surface of the silicon steel sheet is avoided.

Description

technical field [0001] The invention relates to the technical field of iron core manufacturing, in particular to a dry-type transformer iron core clamping device with an automatic alarm function. Background technique [0002] Dry-type transformer refers to a transformer whose iron core and windings are not immersed in insulating oil. The iron core mainly plays the role of supporting and generating a magnetic field inside the transformer. It is mainly composed of multi-layer silicon steel sheets stacked on each other according to a certain rule. Moreover, the size of the gap and the degree of fit between the adjacent silicon steel sheets directly affect the overall quality of the dry-type transformer; in order to adapt to transformers of different specifications, we usually punch out a specific size of silicon steel from the entire silicon steel plate as needed. However, in the process of punching, the cut end is often bent to a certain extent under the action of punching pre...

[0002] Dry-type transformer refers to a transformer in which the iron core and winding are not immersed in insulating oil. The iron core mainly plays the role of supporting and generating a magnetic field inside the transformer. It is mainly composed of multi-layer silicon steel sheets stacked on each other according to certain rules. Moreover, the size of the gap and the degree of bonding between adjacent silicon steel sheets directly affect the overall quality of the dry-type transformer; in order to adapt to transformers of different specifications, we usually punch out silicon steel of a specific size on the entire silicon steel sheet according to needs. However, during the punching process, the cut end will often be bent to a certain extent under the punching pressure, which will not only affect the structural consistency of the silicon steel sheet, but also increase the gap between the silicon steel sheets inside the iron core later. , thus having a certain impact on the product quality of the transformer, so the silicon steel sheet that has just been punched needs to be flattened before use; in the prior art, people usually use a roller press to roll the silicon steel sheet Although this can ensure the flatness of the surface of the silicon steel sheet, the insulating layer on the surface of the silicon steel sheet will be damaged during the rolling process, so usually a second spraying is required after the rolling treatment, which increases the production cost virtually. In addition, in the prior art, the cutting section of the silicon steel sheet produced during the blanking process is exposed to the air for a long time due to neglect, and may be oxidized by oxygen in the air after a long time, thereby affecting the use of the transformer
