The invention discloses a lamination mold of a self-adhesive silicon steel sheet of a long stator, and the lamination mold has the characteristics of convenient operation and uniform compression of the silicon steel sheet. The lamination mold comprises a mold body, a plurality of push rods, disk-shaped springs with the corresponding number of the push rods, pressing plates, pressing springs and wedges. The upper part of each of the wedges is a regular quadrangular prism body, and the lower part of each of the wedges is a quadrangular prism body with inclined planes as elevation faces. The back end of each of the push rods is inserted into a push rod through hole of a front end plate of a base. The push rod passes through the push rod through hole of a column and then is connected with a pressing plate. The pressing springs are sleeved on the push rods and are between the outer surface of the front end plate of the base and the rod caps of the push rods. The disk-shaped springs are sleeved at the rod body back half sections of push rods and are between the step faces of the push rods and the front end faces of the pressing plates. A silicon steel lamination sheet is arranged between the pressing plates and the back end plate of the base. Pressure is applied to the front end parts of the push rods such that the spacing holes of the push rods are aligned with the positioning holes of the cover plate of the mold, the wedges are inserted into the spacing holes of the push rods from the positioning holes of the cover plate, and the lower parts of the wedges are in the spacing holes of the push rods.
Description
technical field [0001] The invention relates to a lamination die for self-adhesive silicon steel sheets of a long stator, which is used for bonding electrical steel sheets with self-adhesive coatings to each other. Background technique [0002] The silicon steel sheet with a self-adhesive coating on the surface is a novel electrical steel material. The surface coating of the steel sheet is heated under a certain pressure to bond the steel sheets together. The magnetic performance of the manufactured iron core is less damaged during use, and the bonding force between the steel sheets is strong. At present, there are mainly four processing forms of molds for pressurization and heating bonding. [0003] The first type of die is a bolt die without a leaf spring. The mold is composed of upper and lower pressure plates with bolts. The iron core is placed between the two pressure plates. With the bolts, the mold and iron core are placed on the press as a whole, and the required p...
