Embodiment 1

[0021] The invention discloses an eye mask water spray device for a wire cutting machine, comprising: a casing 1, an eye mask 2 and a locking device 3.

[0022] Wherein, the eye mask 2 includes a conical section 21 and a cylindrical section 22 integrally connected, and is separately installed in the middle of the casing 1 with the conical section 21 facing the direction of the working fluid leading to the spinneret position 4 . The middle part of the eye mask 2 has a through molybdenum wire guide hole 23 for positioning the molybdenum wire; the two end surfaces of the eye mask 2 are chiseled with a funnel-shaped groove centered on the molybdenum wire guide hole 23 twenty four. The funnel-shaped groove 24 can retain part of the working fluid, so that the molybdenum wire can effectively contact the working fluid during the reciprocating motion, thereby promoting the cooling of the molybdenum wire.

[0023] The locking device 3 is sleeved on the eye mask 2 to realize locking and...

Abstract

The invention discloses an eye mould water spraying device used for a medium-speed wire cut electrical discharge machining machine. The device comprises a shell, an eye mould and a locking unit. The eye mould comprises a conical segment and a cylindrical segment which are integrally connected. The eye mould is mounted in the middle of the shell in a separated mode while the conical segment of theeye mould faces a working solution guide wire spraying position. The locking unit sleeves the eye mould, so that the eye mould is locked and fixed. The locking unit and the shell are arranged in a separated mode. Working solution flow channels are formed among the shell, the eye mould and the locking unit. According to the eye mould water spraying device used for the medium-speed wire cut electrical discharge machining machine, through mixed design of the eye mould and the locking unit, the eye mould is separated from the shell, on the one hand, damage caused by non-uniform stress on the eye mould can be effectively avoided, the service life of the eye mould is prolonged, and the cost is lowered; and on the other hand, the eye mould is more convenient and faster to replace, and the perpendicularity of the eye mould is improved.

Description

technical field [0001] The invention relates to the field of wire cutting machine accessories, in particular to an eye mask water spray device for a medium-feeding wire cutting machine. Background technique [0002] The mechanism of WEDM is to use the principle of "discharge machining" to perform electric erosion (spark discharge) on conductive materials to achieve the purpose of processing. Wire EDM does not need to make forming electrodes. During processing, the electrode wire (usually molybdenum wire) is used as the tool electrode to perform spark discharge on the workpiece. The positive electrode of the pulse power supply is connected to the workpiece, and the negative electrode is connected to the electrode wire. The reciprocating motion continuously enters and leaves the discharge area, and at the same time sprays liquid medium between the electrode wire and the workpiece. The workpiece moves according to the trajectory determined by the program under the control of th...
