Abstract

The invention provides a coordination control system of double metal spiral compound pipe molding and welding, which is mainly composed of a general control system (1), a coordination control subsystem (2) for delivering steel bands and operating a forming machine, a switch coordination control subsystem (3) of inner and outer welding guns and protective gas, a coordination control subsystem (4) of welding speed and steel band molding speed and a control subsystem (5) of welding line tracking and welding quality, wherein, the general coordination control system (1) adopts a programmable logiccontroller (PLC) as an upper computer main controller and is connected with each subsystem; and each subsystem respectively adopts a single chip microcomputer or a DSP to be served as a lower computer subsidiary controller to carry out intelligent control on the subsystems. The control system in the invention has simple and direct composition, simple and applicable structure, low cost, easy debugging and maintaining, and can realize the coordination control of the compound pipe molding and welding with steadiness, accuracy and high precision.

Description

Technical field [0001] The invention relates to a coordinated control system, in particular to a coordinated control system suitable for forming and welding of bimetal spiral composite pipes. Background technique [0002] The composite pipe is composed of two or more different materials, and the pipe layers are tightly combined through various deformation and connection techniques. Plastic-lined composite steel pipes are restricted by life, heat resistance and other factors, so bimetal composite pipes must be used in important occasions. [0003] The bimetal composite pipe has two structures: one is external coating, and the other is internal composite. The outer coated bimetallic pipe is widely used for decoration and structural pipes, and its manufacturing technology is very mature; the inner composite bimetallic pipe is mainly used in fluid transportation to prevent harmful media from corroding the pipeline. This kind of pipe not only improves the pipeline Anti-corrosion abili...
