Cutting device for thin-wall steel pipe

Abstract

The invention discloses a cutting device for a thin-wall steel pipe. The cutting device comprises a machining platform, wherein the upper end face of the machining platform is provided with a sliding connection pushing assembly, the pushing assembly is provided with a moving mechanism, the moving mechanism is provided with a fixed rotating mechanism, one end of the machining platform is provided with a clamping mechanism, the clamping mechanism is provided with an inner supporting round rod in a clamping mode, a frame fixedly connected with the two sides of the machining platform is arranged on one side of the clamping mechanism, first hydraulic rods are symmetrically installed at the upper end of the frame, the telescopic ends of the first hydraulic rods are connected with a cutting unit, a cutting ring groove is formed in the outer side wall of one side of the inner supporting round rod, a limiting rolling device is fixedly installed on the machining platform, and a collecting box is tightly attached to one side of the machining platform. A feeding mode of pushing and moving the steel pipe is adopted, the cutting efficiency is improved, the cut steel pipe is conveniently collected, the cutting stability of the steel pipe is improved, the perpendicularity of a cutting opening is improved, the inner supporting round rod supports an inner cavity of the thin-wall steel pipe, cutting deformation of the steel pipe is effectively prevented, and the quality of the steel pipe is improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a cutting device for thin-walled steel pipes. Background technique [0002] In the field of steel structures, steel pipes whose outer diameter to wall thickness ratio is greater than 20 are called thin-walled steel pipes. Thin-walled steel pipes Thin-walled steel pipes are made by cold drawing. Among them, carbon steel, low alloy steel, and alloy steel thin-walled pipes are suitable for general structures and mechanical structural parts, thin-walled fluid steel pipes are used for conveying general fluids, and stainless steel thin-walled pipes are used for chemical industry, petroleum, light industry, food, mechanical instruments, etc. Industrial heat-resistant containers, conveying pipes and mechanical structural parts.

AI Technical Summary

Problems solved by technology

[0003] When cutting thin-walled steel pipes, cutting blades are mostly used to cut perpendicular to the steel pipe axis. Because the thin-walled steel pipes are easy to cause deformation of the cutting edge and affect the quality of the steel pipes, and it is inconvenient to collect the cut steel pipes. The steel pipes are not easy to fix during cutting, which is easy to cause cutting The mouth is inclined, which increases the subsequent processing procedures, and the steel pipe feed is not easy to transport, resulting in low cutting efficiency
