The utility model relates to a thin-wall steel
pipe cutting device, and aims to solve the problems of uneven
pipe orifice, low precision and the like caused by a traditional
cutting mode. The equipment is composed of a rack component, a
cutting component and a die clamping component. The die clamping component clamps the steel
pipe through the die clamping air cylinder, and the steel pipe is conveyed to a
machining station through the feeding air cylinder. The cutting component comprises a
servo motor, a gear set, a fixed cutter shaft and a movable cutter shaft, the
servo motor drives the blade to rotate, and the cutter pushing air cylinder controls the blade to be pushed out for cutting. The inclined planes of the circular-truncated-cone-shaped blades on the fixed cutter shaft and the movable cutter shaft face opposite directions, accurate cutting can be achieved, notches are neat and smooth, and the size height is accurate. The
machining method comprises the steps of feeding, clamping, feeding, blade rotating, pushing-out cutting and the like. The
machining quality and efficiency of the thin-wall steel pipe can be improved, the follow-up machining
workload is reduced, strict
engineering requirements are met, and wide application prospects are achieved.
