Electric spark automatic deposition device and method using floating telescopic electrode

Abstract

The invention discloses an electric spark automatic deposition device and an electric spark automatic deposition method using a floating telescopic electrode, and belongs to the field of material surface engineering. In the electric spark automatic deposition device using the floating telescopic electrode, an electric spark deposition power supply is connected with a deposition gun, the depositiongun is assembled on the Z axis of a three-dimensional motion platform, and the deposition gun is connected with an electrode material through an electrode floating telescopic mechanism. The electrodefloating telescopic mechanism is composed of a sliding sleeve, a spring or other elastic materials, an electrode adapter rod, a sliding sleeve end and the like, and the rod-shaped electrode materialis directly installed at the end of the electrode adapter rod. When the electrode material is consumed or the outline of the surface of a workpiece fluctuates in the deposition process, the moving electrode can automatically float and stretch under the action of the spring or other elastic materials in the floating telescopic mechanism, so that automatic deposition under the control of a motion program of the three-dimensional motion platform on the to-be-deposited surface of the workpiece is realized.

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...
