Forming device and method for guiding molten metal coating by using metal wire

Abstract

The invention discloses a forming device and a method for guiding molten metal coating by using a metal wire. The forming device comprises a base plate, a spray head, a 3D displacement platform and the metal wire, wherein the base plate is fixed on the 3D displacement platform; the upper end of the metal wire is inserted into a nozzle at the bottom of the spray head and is fixed on the inner side surface of the nozzle, the lower end of the metal wire is suspended in the air, and the included angle between the lower end of the metal wire and the base plate is 90-95 degrees; and the spray head and the metal wire are positioned above the base plate. By adopting the forming device and the method disclosed by the invention, the strain deformation of a pair, caused by the stress, can be effectively reduced, and the accuracy of a formed part is ensured.

Description

technical field [0001] The invention belongs to the field of precision forming, and relates to a metal coating forming device and method, in particular to a forming device and method using a wire to guide molten metal coating.
