Problems solved by technology

At present, the large-mouth spiral corrugations used in construction projects are processed by tile rolling and tailor welding, that is, the steel plates are first rolled into sections of arc-shaped corrugated plates, and then the sections of corrugated plates are staggered and welded manually. This processing method has many steps and is cumbersome. The strength of the welding point is weak and easy to oxidize, and it needs a lot of labor to complete, resulting in low production efficiency and high cost of large-diameter spiral corrugation.

Abstract

The invention relates to a machine tool, in particular relating to a heavy-calibre spiral corrugated pipe machine. The scheme of the invention is as follows: the heavy-calibre spiral corrugated pipe machine is composed of a feeding unit, a shape rolling unit, a seaming and rounding unit and a PLC (programmable logic controller) which controls the machine to operate, wherein the feeding unit is internally provided with an uncoiling machine, the shape rolling unit is internally provided with a shape rolling roller set, and the seaming and rounding unit is internally provided with a seaming mechanism, a prebending roller set and a moulding die. The heavy-calibre spiral corrugated pipe machine is controlled by the PLC, the automation degree is high, the processing efficiency of spiral corrugated pipes is greatly improved, the processing efficiency can reach nearly 20 times that of the traditional process, and the strength of the spiral corrugated pipe is about three times that of the original corrugated pipe.

Description

technical field [0001] The invention relates to an industrial processing machine, in particular to a machine for processing large-diameter spiral corrugated pipes. Background technique [0002] In the process of building and engineering construction, when cement prefabrication is required, such as culverts, column foundations, and underground facilities, it is generally necessary to use large-diameter metal bellows as the support for cement slurry. At present, the large-mouth spiral corrugations used in construction projects are processed by tile rolling and tailor welding, that is, the steel plates are first rolled into sections of arc-shaped corrugated plates, and then the sections of corrugated plates are staggered and welded manually. This processing method has many steps and is cumbersome. The strength of the welding point is weak and easy to oxidize, and a large amount of labor is required to complete it, resulting in low production efficiency and high cost of large-di...
