Telescopic WEDM wire-cutting module and control system and control method thereof

Abstract

The invention discloses a telescopic WEDM wire-cutting module, and further discloses a control system and a control method thereof. The wire-cutting module comprises a bottom plate, an upper tension adjustment module and a lower tension adjustment module symmetrically installed on the left end and the right end of the upper plate surface of the bottom plate, and a wire-cutting wire telescopic adjustment module and a wire-cutting wire slidably connected to the front of the bottom plate. The cutting wire winds fixedly on the upper tension adjustment module, the wire-cutting wire telescopic adjustment module and the lower tension adjustment module. The tension of the wire-cutting wire is adjusted by single-control rotation of an upper wire wheel and a lower wire wheel. A sliding plate with ashape like ']' slides back and forth to drive the wire-cutting wire to expand back and forth. The telescopic WEDM wire-cutting module is small in size and light in weight, can cut large parts, and isfixed on a tool holder of a machine tool through stacking holes on the bottom plate, so that the wire-cutting module is convenient to assemble and disassemble and has good versatility; the control system can adjust the tension of the wire-cutting wire, and can alarm when the tension exceeds a set threshold, and a non-rotating DC motor is used as a damper by loading an adjustable resistance, so that the tension adjustment range is wide, the process cost is low, and the semi-electrodynamic adjustment is time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of wire electric discharge cutting devices, and in particular relates to a retractable wire electric discharge cutting module, a control system and a control method thereof. Background technique [0002] Wire-cut electric discharge machining is a processing technology that uses electric spark discharge to cut and shape workpieces. It has no macroscopic force in the processing process and ignores the hardness and toughness of materials. It is a research hotspot in the field of electrical discharge machining. Wire EDM requires a wire-cutting machine tool. The core system of the wire-cutting machine tool includes a wire-feeding module. The existing wire-cutting wire-cutting module is bulky, heavy, and the extension structure of the fixed wire-cutting wire is fixed and cannot be adjusted. The cutting of the parts has a complex structure, integrated on the wire cutting machine tool, and cannot be disassembled, so...
