Problems solved by technology

[0019] The purpose of the present invention is to overcome the low production efficiency of the existing WAAM process, the purity of the product is completely dependent on the purity of the raw material wire, and the limited quality and diversity of the formed material, and provides a method based on electroslag weight. The method of using the melting additive manufacturing device is a near-net shape rapid additive manufacturing technology that integrates refining, solidification, and forming.

Embodiment 1

[0051] combine figure 1 , the electroslag remelting-based additive manufacturing device of this embodiment includes a consumable electrode 1, a refiner 4, a three-dimensional mobile platform 5, an inert gas supply device 8, a carrier plate 10, an electrode holder 2, and a mounting frame 3. The power supply device 6 and the non-contact temperature measuring device 9, the consumable electrode 1 is located above the refiner 4, the refiner 4 is filled with refining slag, the three-dimensional mobile platform 5 is located below the refiner 4, and the three-dimensional mobile platform 5 Can move freely in three-dimensional space. Among them, the refiner 4 is composed of upper and lower sections, the upper section is a hollow cylinder, and the lower section is an inverted hollow round platform. The upper section and the lower section are seamlessly welded together. The refiner 4 is filled with refining slag. After the lower end of 1 is melted, the liquid droplets pass through the re...

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...
