Abstract

The invention discloses wire-feeding type electron beam material-increasing manufacturing equipment and an operating method thereof. A deflecting and scanning device and a secondary electron receiving device are further mounted on an electronic gun. The deflecting and scanning device and the secondary electron receiving device are connected to a central control unit. When an electron beam sent out by the electronic gun processes a manufacturing layer of a fixed segment of a workpiece, an exciting current of the deflecting and scanning device is controlled by the central control unit, so that the electron beam of the electronic gun turns around to quickly scan the manufacturing layer of the fixed segment, the secondary electron receiving device transmits secondary electronic signals received in a back-scanning process to the central control unit, and the central control unit synchronously records the secondary electronic signal of each scanning point on the fixed segment; after scanning, the central control unit analyzes and processes the recorded secondary electronic signal data so as to determine whether the edge of the manufacturing layer of the fixed segment reaches an expected value or not and determine whether the manufacturing layer of the fixed segment has hole defects or not for the convenience of immediate repair.

Description

technical field [0001] The invention relates to the technical field of electron beam processing equipment, in particular to a wire-feeding electron beam additive manufacturing equipment and an operating method thereof. Background technique [0002] Wire-feed electron beam additive manufacturing equipment requires a vacuum environment for workpiece manufacturing. However, due to the working characteristics of the electron beam additive manufacturing equipment itself, there are inevitably interference factors such as high temperature, strong light, X-rays, metal powder pollution, and electromagnetic fields in the vacuum environment. Therefore, the existing wire-feeding electron beam additive manufacturing equipment still has the following two shortcomings to be overcome: [0003] ①Due to the different degrees of shrinkage of the workpiece under different materials and different sizes, and the vibration of the metal ribbon during the wire feeding process, the size of the workp...
