Pipeline cutting device with rotary cutting function for constructional engineering

Abstract

The invention discloses a constructional engineering pipeline cutting device with a rotary cutting function, and belongs to the technical field of constructional engineering pipeline cutting devices.The constructional engineering pipeline cutting device comprises a workbench, a centering block is slidably arranged on one side of the surface of the workbench, a conical centering block is arranged on one side of the centering block, and a cutting treatment block is arranged on the inner side of the surface of the workbench; and a limiting autorotation rotary cutting mechanism is rotationally arranged in the cutting treatment block, and the first fixing block completes rotation opening and closing of the first fixing block by means of telescopic movement of the fixing telescopic column, so that the inner wall of the pipeline is fixed and loosened by the first fixing block. Through the arrangement of the limiting autorotation rotary cutting mechanism, after the pipeline is fixed, cutting can be conducted through autorotation of the pipeline, at the moment, the pipeline is a power part, a cutter is a static part, the circumferential outer wall of the pipeline can be evenly and rotationally cut, therefore, notches are even, and later use of the pipeline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipe cutting devices for construction engineering, and more specifically, relates to a pipe cutting device for construction engineering with a rotary cutting function. Background technique [0002] Pipes need to be cut during construction. The prior art publication No. CN213796713U provides a pipeline cutting device for construction engineering. The device clamps and fixes the outer wall of the pipeline through two clamping plates. It is still easy to cut when only one end of the pipeline is clamped. When the two ends of the pipe are clamped separately, the clamping structure is relatively complicated, which makes the device bulky. Secondly, the cutting blade is directly exposed after use or when it is not in use, posing a safety hazard. And make the cutting blade easy to rust and affect the service life. The prior art publication numbers CN212121866U and CN212070569U have the same problem. Although the...

The prior art publication No. CN213796713U provides a pipe cutting device for construction engineering. The device clamps and fixes the outer wall of the pipe through two clamping plates. It is still easy to cut when only one end of the pipe is clamped. When the two ends of the pipe are clamped separately, the clamping structure is relatively complicated, which makes the device bulky. Secondly, the cutting blade is directly exposed after use or when it is not in use, posing a safety hazard. And make the cutting blade easy to rust and affect the service life

The prior art publication numbers CN212121866U and CN212070569U have the same problem. Although the cutting blade is set inside the device in CN207952768U, the cutting blade is always inside the device. When the cutting blade needs to be replaced, the whole device needs to be disassembled. Make blade replacement very troublesome
