Embodiment Construction

[0019] The reference signs in the description of the drawings are: electrode wire 1 , nozzle body 2 , guide plate 3 , guide tube 4 , buffer plate 5 , spring 6 , conical sleeve 7 , and fixing rod 8 .

[0020] This embodiment provides a nozzle for a wire cutting machine, such as figure 1 , figure 2 and image 3 As shown, it includes an electrode wire 1, a nozzle body 2, a guide plate 3, a guide tube 4 and a buffer device. The electrode wire 1 is covered with styrene-butadiene rubber, and is fixed in the electrode wire hole in the nozzle body 2 . The conical sleeve 7 is a hollow structure, which can accommodate the working fluid. The bottom surface of the conical sleeve 7 is provided with a through hole, and the wall of the through hole is provided with nitrile rubber. The nitrile rubber has a good sealing effect to ensure the bottom surface of the conical sleeve 7. of sealing. The top of the conical sleeve 7 is welded with a guide plate 3, and the center of the guide plate ...

Abstract

The invention belongs to the technical field of cutting machines and particularly discloses a nozzle for a wire cutting machine. The nozzle for the wire cutting machine comprises a nozzle body and a wire electrode and further comprises multiple fixing rods and a conical sleeve, wherein a wire electrode hole used for containing the wire electrode is formed in the nozzle body, the wire electrode is wrapped by insulating rubber, a through hole is formed in the center of the bottom surface of the conical sleeve, and the nozzle body penetrates through the through hole to be connected with the bottom surface of the conical sleeve in a sealed mode; one end of each fixing rod is fixed to the conical sleeve, the other end of each fixing rod is fixed to the nozzle body, and the multiple fixing rods are distributed along the circumference of the nozzle body; a guide plate is arranged at the top end of the conical sleeve, multiple guide pipes which are communicated with the conical sleeve are formed in the guide plate, and the guide pipes are distributed along the circumference of the guide plate; a wire electrode pipe used for containing the wire electrode is arranged at the center of the guide plate, and the wire electrode pipe is lower than the guide pipes; a liquid inlet channel is formed in the conical sleeve, and an outlet of the liquid inlet channel is parallel to the nozzle body. The nozzle for the wire cutting machine effectively solves the problem that the wire electrode deflects easily.

Description

technical field [0001] The invention belongs to the technical field of wire cutting machine tools, and particularly relates to a nozzle for wire cutting machine tools. Background technique [0002] Wire cut Electrical DiLcharge Machining (WEDM), also known as WEDM, its basic working principle is to use continuous moving thin metal wire (called electrode wire) as an electrode to perform pulse spark discharge erosion on the workpiece. Metal removal, cutting and forming; a strong pulsed electric field is generated between the workpiece (connected to the positive electrode of the high-frequency pulse power supply) and the electrode wire (connected to the negative electrode of the high-frequency pulse power supply), so that the medium between the electrodes is ionized and broken down to form a discharge Once the inter-electrode medium is ionized and broken down to form a discharge channel, the pulsed power supply makes the electrons between the channels run to the positive electr...
