Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a safe cutting machine. Background Art

[0002] When casting parts are processed and produced, most of the casting molds are of the structure of one mold with two cavities or one mold with multiple cavities, which can geometrically improve the casting speed and obtain the casting parts faster. Then, the obtained connected casting parts are cut by a casting part cutting machine to obtain the required independent casting parts;

[0003] When traditional cutting machines are used for cutting casting parts, a large number of splashing sparks will be formed, which is likely to cause certain safety accidents or pollution of the processing environment. Therefore, in the prior art, the cutting machine is placed in a cabinet structure to seal the processing environment and prevent the sparks from splashing. At the same time, in order to facilitate observing the cutting situation of the casting parts, a glass plate is generally embedded in the cabinet door of the conventional cabinet structure, so as to retain the permeability inside the cabinet structure without affecting the sealing effect;

[0004] However, in practice, although the cabinet structure can relatively effectively seal the processing environment of casting part cutting, the spark debris generated by cutting often splashes a large amount and adheres to the glass plate of the cabinet door, so that it needs to be manually wiped and cleaned separately later, which is time-consuming and laborious and affects the use effect. Summary of the Utility Model

[0005] In order to solve the above technical problems, a safe cutting machine is provided, which solves the problem that in the prior art, although the cabinet structure can relatively effectively seal the processing environment of casting part cutting, the spark debris generated by cutting often splashes a large amount and adheres to the glass plate of the cabinet door, so that it needs to be manually wiped and cleaned separately later, which is time-consuming and laborious and affects the use effect.
