Problems solved by technology

[0003] The existing patent "A Method for Electron Beam Surface Micromodeling" (201310041083.4) uses electron beams to scan and move only in the form of points, straight line segments, and arcs. The path style is single and the method is traditional. It can only be based on electron beams. The graphics software provided by the welding machine manufacturer is used for control, and the graphics design and control have obvious limitations, especially in the aspects of multi-point intersection and fast direction change.

Embodiment 1

[0041] The invention provides an aluminum alloy surface modeling method. Specific steps are as follows:

[0042] 1. Design graphics according to the required three-dimensional modeling shape. In this embodiment, it is formed by a C-curve circular array, and one of the C-curve amplitudes (10×5mm) is divided into N 1 =100 data points, carry out numerical calculation through the data points, form a circular array (32 parts), the whole graph has a total of N=3200 points, and the highest frequency at this time is 10 6 / N=3125HZ, and then sort the data in each curve to form a new data group. Finally, the data is imported into the electron beam welding machine control system.

[0043]2. Perform surface mechanical treatment on the surface of the workpiece to be welded, remove oil stains with acetone, alcohol solvent or ultrasonic cleaning, and then place it inside the electron beam welding machine. The distance between the workpiece and the electron gun is about 800mm, and start vac...

Abstract

An electron beam surface rapid shaping method based on vectorized control comprises the following steps that a surface shaping figure and a corresponding vector path are designed, numeric treatment isconducted on the surface shaping figure, numeric figure data are obtained and transmitted to an electron beam machining device for control, and then electron beam surface rapid shaping is achieved. According to the electron beam surface rapid shaping method based on vectorized control, the design figure undergoes numeric treatment, rapid design of multiple kinds of figures is achieved through intersection of data points, the figures are transmitted to an electron beam welding machine for control in a data manner, and electron beam surface rapid shaping of different types of patterns, shapes,arrays, intersections and the like is achieved.

Description

technical field [0001] The invention belongs to the field of metal material surface treatment, in particular to a vectorized control-based electron beam surface rapid modeling method. Background technique [0002] Traditional surface treatment methods currently mainly include sandblasting, shot peening, EDM, laser and other technologies. Such technologies can only be used for surface or near-surface treatment, the shape and spatial form are uncontrollable, and there are disadvantages of low processing efficiency. Electron beam surface modeling technology originates from a cutting-edge technology in the UK. It uses electron beams under vacuum to impact the surface of workpieces to form small-scale molten pools. A directional shaped raised structure is formed below. This technology has the advantages of controllable shape, no pollution, high processing efficiency, etc. It is very suitable for the modeling treatment of the workpiece surface, so as to play a specific functional...
