Embossed pipe manufacturing apparatus for easily welding both sides of embossed metal sheet and embossed pipe manufacturing method using same

Abstract

The present invention relates to an embossed pipe manufacturing apparatus comprising: an uncoiler for providing a planar metal sheet; a centering guide roller for guiding, to an embossing machine at the rear end thereof, the planar metal sheet supplied from the uncoiler; the embossing machine embossing the planar metal sheet supplied through the centering guide roller so as to form same into an embossed metal sheet; and a pipe mill which manufactures an embossed pipe having welded joint parts in a longitudinal direction through a process for curving and circularizing the embossed metal sheet supplied through the embossing machine, and which welds the welded joint parts of the manufactured embossed pipe so as to complete the embossed pipe, and relates to an embossed pipe manufacturing method comprising: a first step of supplying, through the centering guide roller to the embossing machine, the planar metal sheet supplied from the uncoiler; a second step of embossing the planar metal sheet by using an embossing mold roller of the embossing machine, so as to form same into the embossed metal sheet; and the third step of supplying the embossed metal sheet to the pipe mill so as to manufacture the embossed pipe having the welded joint parts in a longitudinal direction through a curving and circularizing process, and welding the welded joint parts of the embossed pipe so as to complete the embossed pipe.

Description

technical field [0001] The present invention relates to an embossing pipe manufacturing device that can easily weld both side surfaces of an embossing metal plate, and an embossing pipe manufacturing method using the same. [0002] In more detail, it relates to an embossed tube manufacturing device and a method for manufacturing an embossed tube, the device comprising: an uncoiler, which provides a flat metal plate; a centering guide roller, which guides the flat metal plate supplied by the uncoiler an embossing machine that guides the rear end; an embossing machine that embosses the flat metal sheet supplied through the centering guide roller to form an embossed metal sheet; The embossed metal plate supplied by the machine is curved and circularized to manufacture an embossed tube with a welded connection in the length direction, and the welded connection of the embossed tube thus manufactured is welded to complete the embossed tube. corrugated tube, [0003] The method inc...

Problems solved by technology

[0038] To provide an embossed pipe manufacturing apparatus that can easily weld both sides of an embossed metal plate and a method for manufacturing an embossed pipe using the same, to prevent the occurrence of the problem of manufacturing an embossed pipe from an embossed metal plate using a common pipe rolling machine The deformation caused by the embossed pattern that occurs when the embossed pattern is compressed and pushed, and solves the dimensional instability caused by the width and elongation of the embossed metal plate, and uses the embossed metal plate that forms a concave-convex surface through embossing to form After embossing the pipe, when you want to weld the connection part, solve the problem that the connection part is inconsistent due to the concave-convex surface and cannot achieve welding, so that the welding scar of the connection part is minimized and the welding scar of the connection part is not exposed to the outside, thus providing a neat finish Processed Embossed Tube
