摘要:
A wire retrieving device for a cutting machine includes a block connected with an air source and a blowing path is defined through the block. A suction path is defined in a side of the block and has an oblique port formed in a surface of the block through which the discarded wire is sucked into the suction path which further has an engaging port communicating with the blowing path. A pushing member removably pushes the metal wire toward the block by an electromagnetic valve when the metal wire needs to be cut by an electrode unit. A pair of driving rollers located a down stream of the electrode unit and pulls the metal wire toward the upper mold. The discarded wire is blowing out from the blowing path and is collected in a collection tank via a tube.

A wire cutting device for an electrical discharge machining (EDM) machine with a wire draw-off device, which moves a wire electrode along a feed direction into a cutting zone of the EDM machine; and with a deflection unit in order to deflect the wire electrode running in the feed direction into the cutting zone from the feed direction into a cutting area, in which at least one cutting edge acts on the wire electrode in the cutting area in order to cut it.

A wire chopper module for processing spent electrode emerging from an EDM system employs replaceable inserts that are also movable relative to the feed path of the electrode. Shifting the position of the inserts relative to the feed path of the electrode allows more than one portion of each cutting edge on the insert to be used. Each insert has more than one cutting edge and can be rotated and re-inserted to present a completely new cutting edge. Removable multi-edge inserts that are repositionable relative to the feed path of the spent electrode permit renewal of the cutting edges of the wire chopper module with increased frequency and reduced cost. The wire chopper module also incorporates a flywheel to increase the movement of inertia of the rotating cutting inserts as an aid in overcoming jams. Sharp cutting edges and increased rotational momentum improve the reliability of the inventive wire chopper module.

An EDM machine in combination with a wire sectioning device. The wire sectioning device has two rotating members consisting of a rotating member 2 having an anvil 16 and a member 3 rotating in the opposite direction. The rotating member 3 has four cutting blades made of a tough material such as tungsten carbide or tungsten nitride. At least one of the anvil and the tool possesses a low moment of inertia to improve the longevity of the sectioning means.
摘要:
A device is disclosed for breaking off the wire-like or strip-like consumed electrode in electro-erosion machines for the processing of workpieces. At a delivery side of the device the consumed electrode is moved by feed rollers into a gap between the surface of an anvil and a multi-edge bit which rotates in front of this surface and is driven by the feed rollers. The rotating bit edges groove the electrode on the anvil surface to cut it into small pieces which fall into a collector container.

A wire electric-discharge machining device and wire-electrode removing device are provided. The wire-electric discharge machining device includes a wire-electrode cutting unit that is arranged in a running path of a wire electrode, and a removing unit configured to remove the wire electrode cut by the wire-electrode cutting unit from the running path. The removing unit includes a wire-electrode guide unit that is arranged below the wire-electrode cutting unit and includes a through hole configured to receive a wire-electrode guide pipe and further configured to receive the wire electrode in the running path. The wire-electrode guide unit is configured to guide an end of the wire electrode to a position outside the running path, with the cut wire electrode provided in the through hole, by rotationally moving about a wire-electrode guide shaft.

A wire aspiration device includes a first member having a first curved surface with a projected portion that is in close contact with peripheral surfaces of first and second recovery rollers on one side, a second member having a second curved surface with a projected portion that is in close contact with the peripheral surfaces of the first and second recovery rollers on the other side, and a third member having a through hole formed in a central portion thereof to cause the ejected wire electrode to run in the wire-electrode recovering direction and coupling the first and second members to form two grooves between the first and second curved surfaces to be in contact with the through hole, wherein a fluid spout for spouting a fluid into the through hole in the recovering direction is formed in any of the first, second, and third members.
摘要:
Cutting device for spark-erosion machine wires in which, after passing through a machining region, the wire-electrode is cut up into sections which are disposed of as waste products into a recovery receptacle. The device comprises electrical contacts connected to a voltage/current source. The wire is subjected to a dielectric fluid whose flow rate is sufficiently high to generate a turbulent flow regime and cause random lateral movements of the wire which sporadically brushes against the contacts.
