Description

Automatic Pipe Cutter

technical field

The utility model belongs to the field of metal cutting machine tools, in particular to an automatic pipe cutting machine.

Background technique

Existing pipe cutters for cutting long pipes are generally grinders or lathes; lathe cutting is to clamp long pipes on the lathe spindle and rotate with the spindle, and the cutting knife is installed on the knife table and fed with the carriage. The knife cuts off the long pipe continuously. The grinding wheel rotates when the grinder grinds the pipe. The long pipe does not move. The high-speed rotating grinding wheel feeds and grinds the long pipe. This method of pipe cutting can only make one workpiece blank at a time, which is inefficient. Moreover, the same tool is always used in the cutting process, which is easy to damage the tool, shortens the life of the tool, and correspondingly increases the processing cost. During the cutting process, the pipe will be slightly bent due to the force applied by the tool perpendicular to the axis of the pipe, which will not only affect The cutting accuracy of the workpiece is also easy to cause the pipe cutter to vibrate.
