Application method for additive manufacturing apparatus based on electroslag remelting

Abstract

The invention discloses an application method for an additive manufacturing apparatus based on electroslag remelting, belonging to the technical field of metal additive manufacturing. The application method comprises the following steps: step A, preparing the apparatus; step B, inputting data into a control computer; step C, clamping a consumable electrode onto an electrode holder; step D, allowing a bearing plate to contact with the lower end of a refining device; step E, controlling energization of the consumable electrode with a power supply device; step F, starting an inert gas supplying device for blowing of molten metal with inert gas; step G, allowing the control computer to control a three-dimensional moving platform to move along X, Y and Z directions; and step H, preparing a target product. The additive manufacturing apparatus in the invention overcomes the disadvantages that a conventional WAAM process has too low production efficiency, the pureness of a product completely depends on the pureness of a raw wire material and materials for formed parts are limited in high quality and diversity, and is a rapid near-net forming additive manufacturing technology integrating refining, curing and shaping into one.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing of metal materials, and more specifically relates to a method for using an additive manufacturing device based on electroslag remelting, which is suitable for the manufacture of hot-working molds, cold-working molds and other metal forming parts. Background technique [0002] As a rapid prototyping technology, additive manufacturing (3D printing) technology is rapidly changing people's production methods and lifestyles. Developed countries such as Europe and the United States and emerging economies have regarded it as a strategic emerging industry. [0003] Metal additive manufacturing technology is generally regarded as the most difficult frontier development direction in the field of additive manufacturing technology. According to the type of heat source, it can be divided into three categories: laser, electron beam and arc. In the past, he mainly studied powder-based metal additi...
