4-2. Principle

 The W11S-60×3200 Three Roller Plate Rolling Machine is based on a PLC programmable controller, equipped with a highly reliable digital display, and a displacement sensor to form a reliable, real-time control system.

(1) PLC programmable controller: W11S-60 × 3200 Three Roller Plate Rolling Machine selected PLC is OMRON CPM1A-40 CDR programmer, composed of CPM1A-40CDR and CPM1A-20ERR1.

(2) Digital display and control system: The system uses the digital display as the core, and is equipped with the corresponding displacement sensor interface. It forms a reliable and real-time control system with the PLC to realize the TNC control of the machine tool.

(3) various movements of machine tools

a, positive and negative rotation of the lower roller motor

The lower roller motor is forward and reversed by the contactors KM11 and KM12. The frequency sensitive rheostat is connected to the rotor circuit to realize the start of the series-frequency sensitive rheostat of the motor rotor, thereby reducing the starting current of the motor. The input modules 00006 and 0007 are turned on, and the CPU and internal programs are controlled so that the 1000 and 1001 output modules are driven to control KA2 and KA3. The KA2 and KA3 are used to control the connection of KM11 and KM12. Since the KM11 and KM12 are connected, the KM10 will be turned on by the time delay output point 1002 of the PLC internal time relay to achieve the time-delay cut-off of the frequency-sensitive varistor.

b. The roller motor moves back and forth

The horizontal movement of the upper roller is controlled by KM21, KM22 and M2 realizes the forward and backward movement of the upper roller, and the input modules 004 and 0005 are turned on to realize the control of the output points 1003 and 1004 of the KM21 and KM22.

c. Roller motor lift

The contactors KM31 and KM32 work separately, so that the M3 drives the lifting and lowering movement of the idler, which is realized by the input points 0010 and 0011 during the adjustment. Output points 1005, 1006 control KM31, KM32.

d, the lifting of the upper roller

The lift of the upper roller is driven by the M4 motor and the hydraulic pump is controlled by the solenoid valve. First press the "oil pump work" button to make the oil pump motor work.
