3D printing cooling and melting device and using method

Abstract

The invention provides a 3D printing cooling and melting device. The 3D printing cooling and melting device comprises a base, wherein a first supporting plate and a second supporting plate are fixedlymounted at the left end and the right end of the top of the base correspondingly; and an auxiliary sliding rod is fixedly mounted between the first supporting plate and the second supporting plate. The 3D printing cooling and melting device has the beneficial effects that the 3D printing cooling and melting device is simple in structure and easy and convenient to operate, a non-connection part (aconnection part, namely a contact part of each layer of printing metal) on the outer side of each layer of printing metal can be quickly cooled and cured, accumulation caused by melting of the metalin the printing process is prevented, meanwhile, the connection part and the center of the interior of the connection part can be kept at high temperature, in the 3D printing process, the phenomena ofserious drooping and deformation of the metal due to untimely cooling are prevented, effective connection of each layer of printing metal is guaranteed, the machining efficiency is not obviously reduced, and the 3D printing cooling and melting device is simple, efficient, convenient, quick and high in practicability.

[0002] At present, metal 3D printer is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials to print Layers of adhesive materials are used to manufacture three-dimensional objects. There are still some problems in the process of using metal 3D printers on the existing market; metals on the existing market are in the process of printing. Metal melting will produce accumulation, and then in the process of printing, serious metal sagging and deformation will occur due to untimely cooling. However, if cooling is carried out, it will cause another problem. When cooling, the thickness of each layer The printed metal will solidify quickly, so that the subsequent accumulated and printed metal layers cannot be effectively hot-melted and connected, and it is very easy to cause it to fall off. Therefore, a special 3D printing cooling and solidifying device is required, which can print on the outside of each layer of metal. The non-connected part (the connected part is the contact part of each layer of printed metal) is rapidly cooled and solidified to prevent the accumulation of metal melting during the printing process, but at the same time to ensure that the connected part and its inner center remain relatively High temperature, so as to ensure the stability and mechanical properties of each layer of metal connection to meet the requirements
