Description

A hand-held wire drawing machine with dust collection function

technical field

The utility model relates to the technical field of wire drawing machines, in particular to a hand-held wire drawing machine with a built-in dust collection function.

Background technique

The working head of the wire drawing machine is usually a steel wire wheel, a sandpaper wheel or a glass wire wheel of other soft materials. Surface brushing treatment is a surface treatment method that forms lines on the surface of the workpiece through the grinding product of the working head, which has a decorative effect; the wire drawing treatment can make the metal surface obtain a non-mirror-like metallic luster, and finally the finished product is obtained by washing. During the wire drawing process, the high-speed rotating steel wire wheel rolls on the surface of the workpiece, which will bring out a lot of harmful dust. At present, most of the handheld wire drawing machines use an external vacuum cleaner to clean the dust. This kind of processing method not only has poor dust suction effect but also is inconvenient to move. Some operators even directly process without a vacuum cleaner in order to improve efficiency. This will undoubtedly cause the operator to inhale dust and bring great harm to their health. Big hidden danger.
