Transformer iron core automatic lamination device

Abstract

The invention belongs to the technical field of transformer accessory manufacturing, and particularly relates to a transformer iron core automatic lamination device which comprises a horizontal bottom plate, a platform is fixedly installed above the bottom plate through supporting columns, a positioning mechanism and a bearing mechanism are installed above the bottom plate, and a stacking mechanism is installed on the bottom plate; in the process of stacking upper-layer silicon steel sheets on lower-layer silicon steel sheets, the silicon steel sheets do not make contact with vertical rods, and the situation that friction is generated between the edges of the silicon steel sheets and the vertical rods is avoided; in the process of mounting a clamping plate after the silicon steel sheets are stacked into an iron core, the limiting effect on a single wedge-shaped block is sequentially relieved, so that a lifting block and a bearing plate move downwards under the action of self gravity, the bearing plate is separated from the bottom surface of the silicon steel sheet on the lowest layer, and the effect of mounting the clamping plate under the condition that the silicon steel sheets are not lifted is achieved; and the condition that extrusion force and friction force are generated between the silicon steel sheets and the vertical rods is avoided.

Description

technical field [0001] The invention belongs to the technical field of transformer accessories production, and in particular relates to an automatic lamination device for transformer iron cores. Background technique [0002] The iron core is the main magnetic circuit part of the transformer. It is usually stacked by hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system. During the production process of the transformer iron core, the silicon steel sheets should be stacked together first, and then the two sides of the iron core should be clamped with splints. [0003] At present, the following problems exist in the manufacturing process of transformer core laminations: (1) In order to ensure the alignment of each layer of silicon steel sheets, it is necessary to use a limit rod to limit the silicon steel sheets. When the u...

Problems solved by technology

[0003] At present, the following problems exist in the manufacturing process of transformer core laminations: (1) In order to ensure the alignment of each layer of silicon steel sheets, it is necessary to use a limit rod to limit the silicon steel sheets. When the upper layer of silicon steel sheets is stacked on the lower layer of silicon steel sheets, the silicon steel sheets The edge is prone to friction with the limit rod, causing damage to the silicon steel sheets; (2) After the silicon steel sheets are stacked, the stacked silicon steel sheets need to be lifted up for a certain distance to install the splint. During this process, the silicon steel sheets are easy to There will be a horizontal offset, resulting in extrusion and friction with the limit rod, which will also cause damage to the silicon steel sheet
