Description

technical field [0001] The invention belongs to the technical field of special electric spark machining, and in particular relates to an ultrasonic electric spark deposition device capable of automatically compensating for electrode loss. Background technique [0002] EDM is one of the important branches of surface strengthening technology. It is a technology that coats conductive materials on the surface of workpieces to improve the overall performance of the surface. The high temperature is instantaneously generated at the top of the electrode, followed by rapid cooling, so that the deposition influence range is small, and the equipment and workpiece are basically kept at room temperature. Therefore, the use of EDM technology can not only improve the service life of the equipment, but also has high environmental protection significance. Due to the advantages of simple operation, small thermal stress and small deformation area, EDM has been widely used in the engineering f...

AI Technical Summary

Problems solved by technology

[0005] 1) Low deposition efficiency: The deposition efficiency can be improved by increasing the discharge gap, increasing the discharge frequency, etc., but at the same time, the deposited layer will not be able to cool quickly, and there will be an obvious heat-affected layer. Therefore, the advantages of EDM compared to other strengthening technologies will be no longer apparent;

[0006] 2) The discharge parameters cannot be adjusted continuously: the discharge parameters need to be set before processing, and the discharge parameters cannot be adjusted during the deposition process. Once adjusted, it will easily lead to uncontrollable discharge energy and unstable discharge;

[0007] 3) It can only process oriented metal materials: Since the electrode and the workpiece need to pass through the circuit after the power is turned on, both the electrode and the workpiece need to be metal materials, and synthetic materials and non-metallic materials cannot be processed.
