Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0028] Example. A suspension mold coating forming method for enameled wire: the coated enameled wire passes through the shaping mold core and enters the enamelling furnace, and the shaping mold core removes excess insulating varnish on the surface of the enameled wire through the forming cavity, and at the same time, the paint liquid forms a squeeze in the forming cavity. The pressure keeps the shaped core in suspension; when the enameled wire is routed, the height of the shaped core is automatically positioned with the enameled wire, and the angle of the shaped core rotates vertically with the threading angle of the enameled wire.

Abstract

The invention discloses a method for forming an enameled wire by painting a suspended mold and a paint film forming mould. The coated enameled wire enters an enameled furnace through a shaped mold core, and the shaped mold core removes excess insulating varnish on the surface of the enameled wire through a forming cavity. At the same time, the lacquer liquid forms an extrusion force in the molding cavity, so that the shaped core remains in a suspended state; when the enameled wire is routed, the height of the shaped core is automatically positioned according to the height of the enameled wire, and the angle of the shaped core follows the threading angle of the enameled wire. Rotate vertically. The invention can make the shaped mold core float and lift along with the enameled wire when the paint film is formed, and has the characteristics that the enameled wire is not easy to be damaged, the production cost is low and the wire is conveniently drawn after the wire is broken.

Description

technical field [0001] The invention relates to an enameled wire forming method and a mould, in particular to a enameled wire suspension mold painting forming method and a paint film forming mould. Background technique [0002] The painted enameled wire needs to undergo a paint film forming process before entering the enamelling furnace, so that the thickness and roundness of the paint layer on the surface of the enameled wire can meet the specified standards. The traditional paint film forming process is to pass the enameled wire through the mats that are attached to each other, and use the mating surface of the felt to wipe off the excess paint on the surface of the enameled wire; During the threading process, obvious creases will be left on the bonding surface, so that the felt cannot completely wipe the paint film at the crease position. [0003] In order to solve the above problems, the current paint film forming method for enameled wire is to set a fixed forming mold ...
