Detailed Description

The following describes the present invention with reference to fig. 1.

Referring to fig. 1, the PC upper computer is used for setting instructions and parameters, and the PLC processes signals into switching variable signals and transmits the switching variable signals to the output module; the output module controls the opening of the hydraulic motor by controlling the electromagnetic valve; each hydraulic motor is provided with a SICK digital encoder, and the SICK digital encoder acquires position signals of the hydraulic motor; the encoder communication module processes the received SICK digital encoder signals; then, after being processed by the PLC, the data are displayed on a PC upper computer. The PC upper computer has two functions of model adjustment and encoder test respectively.

When adjusting the model, only pressing the model adjusting key 1, inputting the corresponding technological requirement value to the window interface under the configuration of a plurality of encoders 8 arranged on the devices at different positions of the host (upper roll, lower roll, side roll, rear roll, etc.) on the interface of the PC upper computer 3, the PC upper computer 3 can transmit the signal to S7-300PLC, the signal is changed into a switch variable signal to an output module 10 through operation processing, the on-off of an electromagnetic 11 in the field direction is controlled, a hydraulic motor 9 is driven to rotate, the encoders 8 in all directions are driven to rotate together through a transmission mechanism, the encoders 8 are converted into digital electric signals along with the mechanical operation of the hydraulic motor 9 to be sent out, the signals are processed to an encoder communication module 7 through a PROFIBUS bus 6, then transmitted to a PLC5, and finally transmitted to the PC3 through the Ethernet, and all the different positions of each device component can be seen on the display screen of the PC3, And (3) the numerical values positioned in different directions are read, and after the read numerical values reach the process set numerical values, the Siemens S7-300PLC5 automatically sends a stop instruction, and the hydraulic motor 9 stops rotating, so that the accurate shape adjustment is rapidly completed, and the steel pipe forming quality is ensured.

During production process, overhaul and model adjustment, self-diagnosis is needed, only the encoder test key 2 is needed to be pressed, the upper computer PC3 sends a signal to the SICK encoder through the PLC5, and if a feedback signal exists, the signal is normal.
