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 present invention relates to a method of adopting programmable logic controller PLC as the main controller of the upper computer for overall coordination, and using single-chip microcomputer or DSP as the sub-controller of the lower computer for each subsystem to carry out intelligent control of the subsystems, especially suitable for bimetal spiral Coordinated control system for composite pipe forming welding. Background technique [0002] The composite pipe is composed of two or more different materials, and the pipe layers are tightly bonded through various deformation and connection techniques. Plastic-lined composite steel pipes are restricted by factors such as lifespan and heat resistance, so bimetallic composite pipes must be used for important occasions. [0003] Bimetal composite pipe has two structures: one is outer cladding, and the other is inner cladding. The outer cladding bimetallic pipe is widely used for decoration and structura...
