Abstract

The invention relates to a multi-pulse digital control type electrospark deposition surfacing power supply, and belongs to precise repairing and surface strengthening technologies in the field of regeneration and manufacturing. The power supply mainly comprises a high-voltage pulse circuit, a low-voltage arc stabilizing circuit and a negative-pressure pulse circuit. In the deposition process, the power supply can output high-voltage pulses to be used for the breakdown of a discharge circuit, and meanwhile outputs low-voltage pulses for arc stabilizing, namely micro arcs in a certain time are formed; transition from electrode materials to workpieces is facilitated, and deposition surfacing efficiency of the power supply is improved. The power supply can output negative-pressure pulses, formed electrosparks can remove high spots deposited on the workpieces, and uniform and dense increasing of a deposition layer is facilitated. By means of high-voltage pulse output and low-voltage pulse output, deposition efficiency can be improved, the high deposition spots on the deposition layer can be removed through the negative-pressure pulses, uniform increasing of the deposition layer is facilitated, and deposition compactness is improved.

Description

Technical field [0001] The invention relates to an electric spark deposition surfacing welding technology, belonging to the field of precision repair and surface strengthening in the field of regenerative manufacturing, in particular to a multi-pulse digital control electric spark deposition surfacing welding power source. Background technique [0002] The working principle of the electric spark deposition surfacing technology is: when the electrode is in contact with the workpiece, the circuit is in a short-circuit state, the power supply outputs a discharge pulse, and a large current density is generated in a small area of ​​the contact point of the electrode and the workpiece to make the contact point The electrode and workpiece material at the location melt and vaporize instantly, triggering spark discharge, and the material melted by the electrode partly transitions to the surface of the workpiece. If the electrode continues to approach the workpiece, the workpiece will be sq...
