Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machine tools, in particular to an electric spark wire cutting machine tool provided with splash protection. Background Art

[0002] Wire cutting machine tools belong to the category of electrical processing. They are mainly composed of machine tools, numerical control systems and high-frequency power supplies. Through multiple cutting, the errors caused by material deformation and molybdenum wire loss are reduced, and the processing quality is relatively improved. Pulse spark discharge is used to erode metal and cut the workpiece into shape.

[0003] Publication No. CN216882146U discloses a spark anti-sputtering structure for an electric spark wire cutting machine tool, which drives the transmission block to move downward on the surface of the screw through a threaded connection transmission block, the transmission block drives the transmission plate to move downward, the transmission plate drives the transmission rod to move downward, and the transmission rod drives the transparent cover to move downward, which plays an anti-sputtering role when the cutting device is working, and solves the problem that most of the existing electric spark wire cutting machines on the market do not have an anti-sputtering function, resulting in sparks flying when the electric spark wire cutting machine tool is working, which affects the surrounding environment;

[0004] However, the above-mentioned wire cutting machine with spark anti-sputtering structure still has the following problems during actual use: although the electric spark can be protected by the lowerable transparent cover, when the electric spark is protected only by the transparent cover, the electric spark will be mixed with metal waste and splash outward, which will cause a large amount of metal waste to adhere to the inner wall of the transparent cover, and the metal waste cannot be collected and adsorbed, which affects the environment of workpiece processing and is easy to cause harm to the operator.

[0005] Therefore, we propose a wire-cut electric spark machine with anti-splash feature to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide an electric spark wire cutting machine with splash protection, in order to solve the problem that when the existing wire cutting machine only uses a transparent cover to protect the electric spark, the electric spark will be mixed with metal scraps and splash outward, thereby causing a large amount of metal scraps to adhere to the inner wall of the transparent cover, and the metal scraps cannot be collected and adsorbed, which affects the environment for workpiece processing and is easy to cause harm to the operator.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric spark wire cutting machine with splash protection, comprising a machine body, and a processing platform fixedly installed on the right side of the top surface of the machine body;
