Nuclear power heavy blank forming process and lcd‑ebam integrated printing equipment

Abstract

The invention discloses a nuclear heavy blank molding process and LCD-EBAM integrated printing equipment. The process sequentially comprises the following steps: establishing a model in a three-dimensional way, and guiding into a molding software program for data processing; running a laser nozzle and an electron beam gun to the origin of coordinates; molding an annular support; molding a cylinder body; molding a top cover and a top spherical shell wall of a deep end socket; molding a cylindrical boss in a pipe connecting section; separating an auxiliary support from a molded part. According to the equipment, a rack is fixed on a bottom beam; a movable cross beam can longitudinally lift and be positioned on the rack; a multi-shaft robot is arranged on the movable cross beam; the laser nozzle and the electron beam gun are respectively arranged on arms of the multi-shaft robot, a laser and a powder feeder are used for respectively providing laser and metal powder to the laser nozzle, and a thread feeder and a power supply are used for providing metal threads and electric power to the electron beam gun; the laser nozzle and the electron beam gun can respectively reach random positions on a workbench; and a controller is used for controlling work of each part. The equipment can be used for realizing high-speed processing of high-precision products and saving energy.

Description

technical field [0001] The invention relates to a nuclear power heavy blank forming process and rapid prototyping equipment thereof, in particular to a nuclear power heavy blank forming process and LCD-EBAM integrated printing equipment. Background technique [0002] With the rapid development of 3D printing technology, 3D printing technology is also used to realize the formation of nuclear power heavy-duty blank parts. At present, there are two kinds of process methods in 3D printing technology, namely laser cladding deposition process (LCD——Laser Cladding Deposition) and electronic Electron Beam Additive Manufacturing (EBAM—Electron Beam Additive Manufacturing), both of which are important 3D printing metal cladding forming processes, LCD uses laser beam energy technology as the enabling technology, and EBAM uses electron beam energy technology as the enabling technology They have their own strengths, among which the accuracy of LCD is higher than that of EBAM, while the c...

[0002] With the rapid development of 3D printing technology, 3D printing technology is also used to realize the formation of nuclear power heavy-duty blank parts. At present, there are two kinds of process methods in 3D printing technology, namely laser cladding deposition process (LCD——Laser Cladding Deposition) and electronic Electron Beam Additive Manufacturing (EBAM—Electron Beam Additive Manufacturing), both of which are important 3D printing metal cladding forming processes, LCD uses laser beam energy technology as the enabling technology, and EBAM uses electron beam energy technology as the enabling technology They have their own strengths, among which the accuracy of LCD is higher than that of EBAM, while the cladding forming rate of EBAM is higher than that of LCD. At present, the two 3D printing technologies are used separately. As a result, when the product 3D printing needs high precision, it can only be carried out at a low speed. If it needs high forming efficiency, it can only form products with low precision requirements, and cannot achieve high-efficiency and high-precision forming.
