Embodiment 1

[0016] Embodiment 1: Referring to Fig. 1 and Fig. 3, the connecting seat (4) is threadedly connected with the wire frame (1), the jewel nozzle seat (2) is put into the connecting seat (4), and the outer circle of the pressing ring (10) is connected to the The wire frame (1) is threaded, and the gem nozzle seat (2) is pressed and fixed on the wire frame (1) by screwing the thread. The gem nozzle seat (2) is embedded with a gem nozzle (3), and there is a mixing chamber (6 ) of the abrasive nozzle seat (5) is threaded on the connection seat (4), and one end extends into the focusing tube (7) in the abrasive nozzle seat (5) that communicates with the mixing chamber (6), and the outer circle of the focusing tube (7) is set The tapered rubber washer (8), the compression nut (9) is threadedly connected with the abrasive nozzle seat (5), the focusing tube (7) is fixed on the abrasive nozzle seat (5), the quick change joint body (11) is connected with the compression The ring (10) is c...

Embodiment 2

[0019] Embodiment 2: Refer to Fig. 2 and Fig. 3, after the water jet has finished piercing the wire hole, keep the X and Y worktables still, raise the lifting arm (16) of the wire frame of the wire cutting machine tool, and remove the abrasive nozzle seat (5) And focusing tube (7), tapered rubber washer (8), lock nut (9), quick change joint body (11) and joint (12), and molybdenum wire (14) passes through the center of the jewel nozzle (3) The small hole, the molybdenum wire is threaded to form a closed loop, and the normal wire cutting process can be carried out. At this time, the gemstone nozzle is used as a molybdenum wire positioner (wire guide nozzle) for wire cutting. Since the punching and the wire-cutting process are based on the same positioning reference, the accuracy of the wire-cutting process is guaranteed.

[0020] There are tapered openings at both ends of the above-mentioned jewel nozzle seat (2), which is convenient for threading. The inner diameter of the g...

Abstract

The invention provides an online perforating device of a linear cutting machine. The perforating device can be used both as a molybdenum wire positioner (wire guiding nozzle) of an electric sparkle linear cutting machine and as a water jet cutting head for perforating linear cut wire thread holes, thus realizing electric sparkle and water jet composite machining. The device comprises a gem nozzle, a nozzle seat, a focusing tube and the like and is characterized in that the gem nozzle of the water jet cutting head and the molybdenum wire positioner (wire guiding nozzle) share one device, therefore the online cutting machine can use the water jet to perforate wire thread holes needed during the linear cutting and machining processes, or can cut metal and non-metal parts on the linear cutting machine. The water jet machining and electric sparkle cutting machining can be carried out on the same one machine, and the problem that the traditional linear cutting and machining can not carry out online perforated thread holes can be solved.

Description

technical field [0001] The invention relates to the technical field of wire electric discharge machining and special water jet processing, in particular to a composite processing method and device for processing wire-cut wire holes with water jet technology, which can be used for online processing of wire-cut holes by wire-cut machine tools. Background technique [0002] Wire-cut electric discharge machining is a processing method in which the high temperature generated at the moment of pulse discharge between the workpiece material and the molybdenum wire poles of the electrode is used to ablate the workpiece to remove the material. In order to improve the machining accuracy of wire electric discharge cutting, it is necessary to position the molybdenum wire at high speed. On the other hand, the wire hole must be pre-processed before processing to pass through the electrode molybdenum wire. The precision of threading hole processing has an important impact on the accuracy o...
