Open-close wire guiding water jet plate for high-speed reciprocating wire-feeding wire-cut electric discharge machine

Abstract

An open-close wire guiding water jet plate for a high-speed reciprocating wire-feeding wire-cut electric discharge machine comprises a base (1) provided with mounting holes (2). The open-close wire guiding water jet plate is characterized in that the base (1) is provided with a left collet (4), a left gem block (5) is mounted on the left collet (4), a semicircular or V-shaped through groove is arranged on one side of the left gem block (5), a right gem block (7) is mounted on a right collet (9), a semicircular or V-shaped through groove is also arranged on one side of the right gem block (7), a wire guiding hole (13) and a wire electrode guiding groove (12) are arranged on the base (1), the right collet (9) is mounted on a rotary pressing block (10), one end of the rotary pressing block (10) is pivotally mounted on the base (1), the other end of the rotary pressing block (10) is provided with an actuation device (14) connected with the base (1), and a hydrojet nozzle (15) is mounted on the base (1) and connected with an operating fluid outlet end. The open-close wire guiding water jet plate is simple in structure and long in service life, and wire electrodes are conveniently hung in a guide wheel.

Description

technical field [0001] The invention relates to a wire electric discharge cutting technology, in particular to a wire guide water spray plate used for liquid spray cooling and electrode wire limit so that the electrode wire can be moved smoothly in the wire electric discharge cutting process, specifically a high-speed reciprocating motion Open and close guide wire water spray plate for wire electric discharge machine tool. Background technique [0002] As we all know, in the process of high-speed reciprocating WEDM processing, due to the high-speed operation of the electrode wire, the vibration and regular reversing of the electrode wire will cause the spatial position of the electrode wire to change, which will seriously affect the machining accuracy and surface quality. The threader is the key component to solve this problem. The wire guides used on the high-speed reciprocating wire electric discharge machine tool are currently mainly limited to two types: the limit r...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of the ring type and the limit rod wire guide used in the existing high-speed reciprocating wire electric discharge machining process, which have poor limiting effect and inconvenient threading, and design a By adjusting the fastening position of the gem seat to compensate for the wear of the gemstone, it can achieve long-term stability and omnidirectional limit function. It can also simply and quickly hang the electrode wire on the guide wheel and combine it with the water spray plate. Guide wire spray plate
