Abstract

The invention discloses an indirect resistance heating device for a wire feeding process during additive manufacturing, and belongs to the technical field of electric heating parts. The lower end of ashell sleeve assembly is connected with a bolt nut fastening assembly which is fixed on a base; the shell sleeve assembly is fixedly provided with an indirect resistance hot wire assembly through fastening screws, and the wire feeding direction is adjusted by an eyelet bolt; an end part of the indirect resistance hot wire assembly is provided with a wire feeding nozzle joint which is connected with a wire feeding nozzle; the indirect resistance hot wire assembly is connected to a 220V standard voltage, wherein heat is generated by an electric heating effect of a soldering-iron-core heating wire, and after passing through a heat conducting pipe, a fine metal wire in a wire feeding process during additive manufacturing is preheated; a wire-feeding hose joint is fixedly connected to the shell sleeve assembly; and the wire-feeding hose joint is connected to a wire-feeding hose and fastens the wire-feeding hose by a fastening screw. The device has a simple structure, is convenient to operate and has a good effect.

Description

technical field [0001] The invention specifically relates to an indirect resistance heating device in the wire feeding process of additive manufacturing, and belongs to the technical field of electric heating components. Background technique [0002] Additive manufacturing technology, also known as 3D printing technology, is an advanced technology that directly manufactures physical parts by accumulating materials layer by layer through CAD design data. Additive manufacturing technology can complete the manufacture of many complex structural parts that are difficult to complete by traditional processing, and greatly reduce the processing steps and shorten the construction period. At present, it has been widely used in the development of new products and the production of small batches of complex parts. [0003] Additive manufacturing technology is mainly divided into powder-feeding additive manufacturing and wire-feeding additive manufacturing according to the different mat...
