Self-bonded coil forming machine and process

Abstract

The invention discloses a self-bonded coil forming machine and a self-bonded coil forming process. A winding mechanism is arranged on the forming machine and comprises a winding shaft and a winding chuck which can rotate along with the winding shaft; the self-bonded coil forming machine also comprises a coil heating system; and the heat spray opening of the coil heating system is opposite to a semi-finished self-bonded coil wound on the winding chuck. The coil heating system is arranged on the self-bonded coil forming machine, so that the semi-finished self-bonded coil can be heated and baked after being wound; a self-bonded layer on the outer layer of an enamelled wire is softened and formed through bonding, namely one set of equipment can be used for winding and baking; the production process is simple; a small amount of equipment is involved; the time consumption is low; the production efficiency is high; resources are saved; furthermore, the self-bonded coil is wound and baked on the same equipment, so that the self-bonded coil is not required to be transferred to an oven and heated after being wound; phenomena of rebounding and loosening of the coil during transferring are avoided; and the qualified rate of a product is increased.

Description

technical field [0001] The invention relates to a self-adhesive coil forming machine and a self-adhesive coil forming process, in particular to a self-adhesive coil forming machine with winding and baking functions and a self-adhesive coil forming process using the forming machine. Background technique [0002] The surface of the copper wire is wrapped with insulating varnish to form a copper enameled wire, referred to as copper wire or enameled wire. The enameled wire is divided into: solderable type, that is, the enameled layer can be melted by tin temperature; non-solderable type, that is, the enameled layer cannot be melted by tin temperature. A special method is required to solder after removing the paint layer; self-adhesive type, that is, after winding the wire package, the windings can be glued together after certain treatment. [0003] Self-adhesive enameled wire has certain quality characteristics and is used for winding self-adhesive coils for specific occasions. ...

AI Technical Summary

Problems solved by technology

[0006] The self-adhesive coil baked in the oven is the formed self-adhesive coil. However, in this self-adhesive coil forming method, the winding and baking are carried out separately on two sets of equipment. The production process is complicated, the equipment requirements are large, and the time is long. , the production efficiency is low; and in the process of transferring the wound self-adhesive coil from the winding machine to the oven, the wound coils tend to bounce back, the volume of the coil cannot meet the design requirements, and the defective rate of the self-adhesive coil reaches 4%. serious waste of resources
