Abstract

The invention discloses a grouping type micro electrical discharge machining pulse power supply. On the basis of a traditional RC type pulse power supply, the power supply adopts a flyback circuit to synchronously charge multiple groups of energy storage capacitors, gating of different discharge loops is achieved by using an FPGA to control on-off of a secondary side switching tube and a relay, and multiple levels of energy output can be provided by cooperatively adjusting the conduction duration of a primary side switch tube. The problems that the traditional RC type pulse power supply is long in charging time, large in resistance energy consumption and uncontrollable in discharging energy are effectively solved, the micro electric spark machining efficiency is improved, and meanwhile the machining quality and precision requirements are met.

Description

technical field [0001] The invention relates to the field of pulse power supplies for electric discharge machining, in particular to a grouped micro electric discharge machining pulse power supply. Background technique [0002] With the development of my country's machining industry in recent years, the market demand of the machining industry has put forward higher requirements for the size, precision and processing efficiency of micromachining. As a new non-contact manufacturing method, micro-EDM is suitable for special processing occasions such as complex shapes and special parts of difficult-to-cut materials. It has the advantages of low stress, no burrs, and can process high-hardness materials. It can be widely used in the machining of shaft holes and cavities. [0003] With the development of micro-EDM, the machining industry pays more attention to machining accuracy, quality and machining efficiency under the condition of satisfying its basic application occasions. F...
