Applied to the device for photographing the discharge channel of slow-moving wire electric discharge cutting

Abstract

The invention provides a device used for shooting a low-speed wire cut electrical discharge machining discharge channel. The device comprises a bottom plate, a junction plate, connection plates, Z-shaped iron parts and guide columns. The junction plate and the bottom plate are spliced and form a bottom plane together. The connection plates are arranged on the lower surface of the bottom plate andthe lower surface of the junction plate and are used for fixing the bottom plate and the junction plate. One end of each Z-shaped iron part is fixedly connected with the bottom plate through bolts, and the other end of each Z-shaped iron part is fixedly connected with the corresponding connection plate through set screws. The guide columns are arranged at the positions of four vertex angles of thebottom plane through countersunk bolts. The connection portions of the bottom plate and the junction plate are each arranged into a stair shape for splicing. A water leakage groove is further formedin the bottom plate. An electrode wire penetrates through the water leakage groove. A flow limiting plate used for covering the water leakage groove is further arranged on the junction plate. The junction plate and the connection plates are fastened and connected through two bolt and nut connection pieces.

Description

technical field [0001] The invention belongs to the field of machine tool processing, and in particular relates to a device for photographing slow-moving wire electric discharge cutting discharge channels. Background technique [0002] Slow-moving WEDM wire cutting uses continuously moving thin metal wires as tool electrodes, and the high temperature generated by pulse discharge is used to etch the metal, thereby cutting and forming. As one of the special processing technologies, WEDM has no macroscopic cutting force during cutting, and can process conductive materials of any strength, hardness and stiffness with high processing accuracy and good processing quality. Therefore, wire electric discharge machining technology has a wide range of applications in the aviation industry, molds, medical equipment and so on. [0003] WEDM is the result of the comprehensive effects of heat, electromagnetic force, fluid power, electrochemistry and colloid chemistry. According to the pro...

Problems solved by technology

[0004] When shooting the discharge channel of wire electric discharge cutting, for the machine tool of water flushing slow wire electric discharge cutting processing, such as figure 1 As shown, since the high-pressure deionized water is sprayed from the nozzle and directly rushes to the workpiece and the electrode wire, causing water splashes, so in actual processing, it is necessary to use a cloth to prevent high-pressure water from splashing, so that the processing area is blocked, which is not conducive to shooting, and the high-pressure deionized water passes through the processing area, which will cause the spark shooting to be disturbed by the water flow, making the shooting unclear
