Novel transformer insulation plate bending device

Abstract

The invention provides a novel transformer insulation plate bending device, which comprises a stock, a clamping part, and a bending part, wherein the clamping part comprises a fixing plate, a leadscrew nut mechanism, a cylinder mechanism and a lower pressing plate, the middle of the fixing plate is provided with a rectangular placement groove along the length direction, the left side and the right side of the placement groove are convex, the leadscrew nut mechanism transversely passes through the convex part of the placement groove, the cylinder mechanism is fixed on the top wall of the stock, and the lower pressing plate is located at the upper part of the placement groove and fixed on the cylinder mechanism; and the bending part comprises a supporting shaft seat, a rotating pressing plate and a handle, the rotating pressing plate and the supporting shaft seat are hinged and connected, and the handle is fixed on the rotating pressing plate. The level principle is used for realizing bending operation on the insulation plate, multidirectional positioning is carried out on the insulation plate during the bending process, the insulation plate is stably fixed, labor intensity is reduced, and the problem of rebound deformation of the insulation plate can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of transformer component manufacturing, and in particular relates to a bending device for a novel transformer insulating plate. Background technique [0002] In the low-voltage winding of the transformer, an insulating plate needs to be placed between adjacent aluminum foils to achieve the effect of magnetic shielding, and the insulating plate is mostly made into a cylindrical shape. The existing insulating plates include cardboard, rubber plates, etc., and are mainly made by hand. The process of bending is cumbersome and labor-intensive. Moreover, due to insufficient bending strength and unstable positioning of the insulating plate during the bending process, it is easy to rebound and deform, which affects the insulation effect of the transformer. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a new type of ben...
