A kind of electrospark automatic deposition device and method using floating telescopic electrode

Abstract

The invention discloses an electric spark automatic deposition device and method using a floating telescopic electrode, belonging to the field of material surface engineering. In the EDM automatic deposition device using floating telescopic electrodes, the electrofiring deposition power supply is connected to the deposition gun, the deposition gun is assembled on the Z axis of the three-dimensional motion platform, and the deposition gun is connected to the electrode material through the electrode floating telescopic mechanism. The electrode floating telescopic mechanism is composed of sliding sleeves, springs or other elastic materials, electrode adapter rods, sliding sleeve ends and other parts, and the ends of the electrode adapter rods are directly installed with rod-shaped electrode materials. When the electrode material is consumed during the deposition process or the contour of the workpiece surface fluctuates, the electrode moving electrode can float and expand by itself under the action of the spring or other elastic materials in the floating expansion mechanism, so as to realize the three-dimensional motion platform motion program on the surface of the workpiece to be deposited Automatic deposition under control.

Description

technical field [0001] The invention relates to an electric spark automatic deposition device and method using a floating telescopic electrode, belonging to the field of material surface engineering. Background technique [0002] EDM is the use of capacitance to store electrical energy to form a high-frequency pulsed micro-arc discharge (10 -6 ~10 -5 s), the gas between the substrate and the electrode is ionized to form an instantaneous channel, and the electrode material migrates to the surface of the substrate under the action of an electric field, and forms a continuous coating through the electrode movement. The heat input of EDM deposition is small, and the heat-affected zone and deformation caused by the workpiece are small; the deposition coating and the substrate are metallurgically fused, and the bonding strength is high; the electrode material that is locally melted at the instantaneous high temperature of the EDM cools rapidly on the surface of the workpiece, and...
