Automatic core discharging device for electro-spark wire-electrode cutting peripheral hole slot of tubular part

Abstract

The invention discloses an automatic core discharging device for an electro-spark wire-electrode cutting peripheral hole slot of a tubular part. The automatic core discharging device comprises a clamping mechanism and a clamp main body, wherein a jet-flow channel is arranged inside the clamp main body; a jet-flow spray nozzle is arranged in the jet-flow channel; the jet-flow spray nozzle is positioned behind a lower hole slot and is adjacent to the inner hole wall of the tubular part; the jet-flow channel is provided with at least one first connecting channel in an outward extending mode; thejet-flow channel is provided with an external fluid jet-flow connector which comprises a second connecting nozzle, a fluid conveying pipeline and a feed-in mechanism. According to the scheme adopted by the invention, the jet-flow channel which extends towards the inner part and the jet-flow spray nozzle are arranged on the clamp main body, so that blocky material cores can be automatically discharged, and therefore, a discharge process is smoother and quicker to prevent material core retention from affecting follow-up wire cutting; the feed-in mechanism is used for driving the second connecting nozzle in the fluid jet-flow connector and the first connecting nozzle to automatically separate and combine so that automatic continuous operation of an electro-spark wire-electrode cutting machinetool and material core discharge is guaranteed, and automatic production needs are met.

Description

technical field [0001] The invention relates to the technical field of electric discharge wire cutting machine tools, in particular to an automatic discharge device for material cores used in the processing of circumferential hole grooves in the wire electric discharge cutting of tubular parts. Background technique [0002] The wire electric discharge cutting device (machine tool) uses the principle of electric discharge machining, uses metal wire as the processing electrode tool, and applies a pulse power supply between the workpiece and the electrode wire (copper wire, molybdenum wire) to utilize the power generated between the electrode wire and the workpiece. The workpiece is corroded by spark discharge, and at the same time, the workpiece and the electrode move according to the required shape to cut a certain shape of the workpiece. In order to achieve relatively high cutting accuracy and surface quality, often this kind of machine tool is Multiple cuts are required for...
