Abstract

The invention relates to a double-layer coiled welded pipe production line programmable logic controller (PLC) control cabinet for a control device on a continuous type double-layer coiled welded pipe production line. A PLC in the control cabinet is connected with an encoder, a touch screen, a frequency converter, an infrared minimeter, a silicon controlled electric power regulator, a flaw detector, a pressure sensor and production equipment respectively and is communicated with the touch screen and the frequency converter respectively through the Ethernet and an equipment network to form a three-step control network. In the control cabinet, closed loop control is adopted, so that the control accuracy of parameters such as temperatures, speed and the like is improved; and real-time monitoring, alarming and controlling functions are integrated, so that the influences of personal factors during production are reduced, and the safety and the stability of production line operation are improved.

Description

technical field

[0001] The invention relates to a control device for a continuous double-layer coiled welded pipe production line. Background technique

[0002] The double-layer coiled welded pipe used in the automobile and refrigeration industries is a special product formed by curling a steel strip coated with solder such as copper on both sides 720° along the width direction to form a double-layer coil, and then welding the tube tube through a heating device. Pipe, the production line of this kind of pipe is generally composed of uncoiler, forming machine, brazing furnace, eddy current flaw detector, marking device, tractor, and coiling machine. The production process not only requires the coordination of the actions of each production equipment, but also requires The control requirements of process parameters such as operating speed, brazing temperature, tension, and air pressure are extremely strict. The traditional tube production line control system uses relays, Y ser...
