Problems solved by technology

[0002] In the current large-diameter pipe cutting devices, most of the systems use a rotating blade to cut a small opening smaller than the diameter of the rotating blade on one side of the steel pipe when cutting the pipe, and then rotate the steel pipe for a circle. The steel pipe is gradually cut; this method has the complex structure of the pipe cutting device and the long cutting time, which makes it difficult to improve the production efficiency and also affects the roundness of the steel pipe

Embodiment Construction

[0009] First, according to the diameter of the pipe, the center of the cutting knife is adjusted to the center of the pipe of the specification by adjusting the screw rod, the feeding baffle of the automatic storage feeding bin rises, the steel pipe automatically rolls to the conveying channel of the steel pipe conveying device, and the feeding baffle descends; The feeding positioning baffle rises, the feeding motor drives the front end of the feeding fixture to extend into the pipe and pushes the front end of the steel pipe forward to the reference baffle, the feeding motor stops, the feeding fixture clamps the workpiece from the inner wall of the pipe, the feeding positioning baffle descends, and the steel pipe is fed axially The pre-positioning is completed; the feeding motor starts to feed again, and the feeding fixture pushes the steel pipe to feed forward. When the feeding sensor detects the steel pipe in-position signal, the feeding motor stops and the feeding is complete...

Abstract

The invention discloses a system for cutting off a steel pipe or a tubular object. The system mainly comprises an automatic storage loading cabin, a steel pipe conveying device, a multi-specification caliber pipe cutting device and an electrical control system, and is mainly characterized in that the automatic storage loading cabin is connected to the steel pipe conveying device and then is connected to the multi-specification caliber pipe cutting device, and the whole machining process is fully automatically performed under the control action of the electrical control system. Four cutting tools are arranged on unfolding and folding nuts of a screw rod respectively, and the screw rod is driven to rotate through a friction wheel in the process of rotating a rotary cutter plate rack so as to feed the cutting tools. The four cutting tools are used for circumferentially cutting the steel pipe in a laminated mode, so that the roundness of the steel pipe is ensured, and the cutting efficiency is improved.

Description

technical field [0001] The invention is a system for cutting steel pipes or tubular objects, mainly used in steel pipes or tubular workpiece cutting processing equipment, and is a complete set of devices from storage and feeding of steel pipes, pipe cutting and feeding to completion of pipe cutting. Background technique [0002] In the current large-diameter pipe cutting devices, most of the systems use a rotating blade to cut a small opening smaller than the diameter of the rotating blade on one side of the steel pipe when cutting the pipe, and then rotate the steel pipe for a circle. The steel pipe is gradually cut; this method has the complex structure of the pipe cutting device and the long cutting time, which makes it difficult to improve the production efficiency and also affects the roundness of the steel pipe. Contents of the invention [0003] The purpose of the present invention is to adopt the most reasonable structure to realize fast and efficient cutting of la...
