Problems solved by technology

[0003] Domestic patent 200420080650.3 Although the self-piercing EDM machine can realize pre-piercing processing before wire EDM, avoiding the error of secondary clamping and positioning, but the piercing part can only be fed up and down, and the processing function is single, wire cutting and piercing Processing cannot be done alone
The device of the domestic patent 200620061316.2 is connected with the perforating mechanism on the wire-cutting machine tool, which can only realize the pre-punching function of the wire-cutting machine tool, and the perforating device cannot be applied to more types of wire-cutting machine tools, which limits the secondary development
Domestic patent 200620040996.x can be flexibly applied to auxiliary perforation processing of various wire-cutting machine tools, but its degree of automation is low and cannot meet the needs of modern CNC machining and multi-functional perforation

Abstract

The invention relates to a combined punching device for an electric spark wire cutting machine tool. The device comprises modules and mechanisms such as a high-frequency pulse power supply, a special clamp, a connector, a punching mechanism, a control and detection system, a stepping system, a micro-stepping system, a working fluid circulating system and the like. The device can finish pre-punching and subsequent processing by realizing one-step clamping and positioning through the special clamp in combination with electric spark wire cutting machine tools of various models. When the device works independently, processing of holes of various sizes can be finished. In combination with a pico-joule high-frequency pulse power supply and a fine electrode and a special-shaped electrode which are processed by an online grinding mechanism, the device can realize processing of fine holes and special-shaped holes under the driving action of a high-accuracy photoelectric micro feeding system.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a combined perforating device and a perforating process for a wire electric discharge machine tool. Background technique [0002] With the rapid development of mold industry production, wire electric discharge cutting technology has been widely used in mold processing industry, and 60% of cold stamping dies are completed by wire electric discharge cutting machine. The current wire electric discharge cutting must carry out electric spark perforation in advance in the processing process, which will cause the error of the second clamping. Nowadays, machine tools require precision, even ultra-precision. As an advanced manufacturing technology, WEDM needs to improve the machining accuracy from the perspective of machine bed design itself and machine tool processing technology in order to improve the precision of the workpiece. Reducing or eliminating the error of secondary clampi...
