Description

[0001] Technical field: [0002] The invention relates to the technical field of non-ferrous metal processing and testing equipment, in particular to an automatic closing door device for a model line end milling protective cover. Background technique [0003] The protective cover is to prevent the chipping during processing from splashing out and hitting people when processing such as turning and milling, so as to avoid potential safety hazards. The protective covers of the existing milling machines are all manual. Generally speaking, the protective covers are made of iron and are relatively heavy. It takes a lot of effort to open and close. This will undoubtedly increase the labor burden of the operator. During processing such as turning and milling, it will cause the chipping during processing to splash out and hit people, which poses a safety hazard. Contents of the invention [0004] The object of the present invention is to provide an automatic closing door device for ...
