Parallel discharge multi-electrode wire carrying mechanism and balance discharge control method

Abstract

The invention discloses a parallel discharge multi-electrode wire carrying mechanism and a balance discharge control method thereof. The wire carrying mechanism comprises a unique axial multi-section type wire storage cylinder and a multi-wire gathering and cutting guide wheel set. The axial multi-section type wire storage cylinder is a key part for realizing synchronous take-up and pay-off of multiple electrodes, and can wind multiple electrode wires on the same wire storage cylinder at intervals to realize mutual insulation of the multiple electrode wires and high-speed synchronous reciprocating wire feeding; and the multi-wire gathering and cutting guide wheel set comprises three structures of a multi-guide-wheel staggered arrangement type, a multi-groove guide wheel type and a mixed type, and can be respectively adapted to meeting such multi-wire cutting demands as thin slices, high consistency and multiple cutting wires. The wire carrying mechanism can greatly improve the machining efficiency of electrospark linear cutting, and has such advantages as the simple equipment structure, wire gap adjustability, long service life, stable and reliable operation and good machining quality.

Description

Technical field [0001] The invention relates to an electric discharge machining technology, in particular to a wire-moving technology of a wire-cut EDM machine tool, in particular to a wire-moving mechanism of a multi-electrode wire-cut EDM machine tool with parallel discharge and a balanced discharge control method. Background technique [0002] The basic working principle of wire EDM is to use continuously moving fine metal wires (called electrode wires) as electrodes to perform pulse spark discharge to remove metal from the workpiece, and finally achieve the purpose of cutting and shaping. The wire transport mechanism is the most important mechanical device in the wire EDM machine tool, which is responsible for driving the electrode wire to move along its axial direction. There are two types of wire transportation: high-speed wire and low-speed wire. The wire electrode in the high-speed wire mechanism can be used repeatedly, and the wire electrode in the low-speed wire is only...
