Description

Technical Field

[0001] The present application relates to the technical field of enameled wire production, and in particular to a die head oven for an enameling machine. Background Art

[0002] When processing bare wire into enameled wire, existing enameled wire production lines first use an annealing furnace to anneal and soften the bare wire, then paint the surface of the bare wire to form an insulating layer, then apply wax on the insulating layer to form a wax oil layer, and finally roll up the waxed enameled wire.

[0003] However, since part of the wax layer on the enameled wire has not completely dried before winding, it is easy for some of the wax that has not dried to drip onto the ground and equipment when winding the enameled wire, causing the ground and equipment to be dirty, or these wax drips onto other enameled wires and affect the final quality of the enameled wire.

[0004] In view of this, it is necessary to provide a head oven for an enameling machine. Utility Model Content

[0008] By adopting the above technical solution, after the wax layer on the enameled wire is applied, workers can first insert these enameled wires into the box from the wire inlet hole. The heating device will blow hot air into the box through the pipe to dry the wax on the enameled wire entering the box. Then these enameled wires are taken out of the box from the wire outlet hole and wound up, so as to ensure that the wax on the enameled wire is completely dry when winding the enameled wire, and will not drip from the enameled wire.
