Abstract

The invention relates to a high-strength drawing magnetic slot wedge, which is characterized in that a glass fabric bonded with iron powder through an adhesive is rolled, wrapped, folded, pressed, drawn and molded to form an integrated structure formed by wrapping the adhesive and the iron powder with an outer glass fabric, and a manufacturing method of the high-strength drawing magnetic slot wedge comprises the steps of adhesive preparation, glass fabric gluing, powdering and drawing molding. The automatic production process is adopted, batch production of the drawing magnetic slot wedge can be achieved, the edge of the manufactured magnetic slot wedge does not need to be cut, iron powder is not prone to falling off, and the magnetic slot wedge has the advantages of being large in bending strength, high in magnetic permeability and the like.

Description

technical field

[0001] The invention relates to the technical field of magnetic slot wedges, in particular to a high-strength drawing magnetic slot wedge and a manufacturing method thereof. Background technique

[0002] At present, domestic magnetic slot wedge products are only made by lamination, which cannot avoid cutting defects on the side and structural collapse due to delamination during use. And there is no production, manufacture and sale of drawing magnetic slot wedge at present. Patent CN101295894 discloses a production method for drawing magnetic slot wedges. The production steps mainly include steps such as compounding glue, alkali-free glass fiber dipping, drawing molding, cooling cutting, grinding head, surface treatment, etc., and the manufactured magnetic slot wedges are Under normal conditions, the bending strength is ≥200MPa, and the relative magnetic permeability is ≥3.2 under the magnetic field strength of 1000 Oe. However, the production steps did not ...
