Embodiment Construction

[0025] device embodiment.

[0026] refer to figure 1 . The present invention is based on an electron beam fuse additive and subtractive composite manufacturing device, which includes an electron beam additive forming part, a material subtractive processing part and a host computer control system 1 working on the same motion platform. Wherein the motion platform 12 is arranged on the base, and can move in X, Y, Z directions and rotate around the Z axis. The vacuum device provides a vacuum working environment for the electron beam in the preparation stage (1×10 -3 Pa). The electron beam additive forming part includes an electron gun 9 (60kV / 8kW) that emits an electron beam 8; the electron gun deflection control system 11 controls the electron gun to emit the electron beam 8 according to the signal of the host computer control system 1 for deflection heating, so that the metal wire to be processed is melted into Liquid state, or by heating the spraying area, the spraying area...

Abstract

The invention discloses an additive and subtractive combined manufacturing device and method based on electron beam fuse which are used for solving the technical problem of poor practicability of existing additive and subtractive combined machining systems and methods. According to the technical scheme, the device comprises an electron beam additive forming part, a subtractive machining part and an upper computer control system; the electron beam additive forming part comprises an electronic gun emitting the electron beams, an electronic gun deflection control system, a container for containing to-be-machined metal wires, a spray head and a metal wire feeding mechanism; the subtractive machining part comprises a mechanical arm, an internally-cooled cutter and an end effector mounted on the mechanical arm, the end effector of the mechanical arm is provided with a quick-change device, and subtractive machining is implemented; a cooling unit connected with the internally-cooled cutter is used for cooling the internally-cooled cutter and controlling the temperature of the internally-cooled cutter; and both the additive forming part and the subtractive machining part are placed in a vacuum chamber. With the device and the method, additive and subtractive combined machining is realized, and the practicability is high.

Description

technical field [0001] The invention relates to an electronic beam fuse-based additive and subtractive material composite manufacturing device, and also relates to a method for using the device to perform additive and subtractive material composite manufacturing. Background technique [0002] Electron beam rapid prototyping of metal parts is a new metal solid additive processing technology developed in recent years. The principle is to obtain the two-dimensional profile information of each layer section and generate the processing path through the layered slice processing of the three-dimensional digital model of the part, and use the high energy density electron beam as the heat source to melt the filling material in the vacuum chamber according to the predetermined processing path. (wire material or pre-laid powder), stacked layer by layer, and finally achieve near-net manufacturing of dense metal parts. [0003] When the raw material for electron beam fuse forming is met...
