The slitting line manufacturer introduces many kinds of control methods for the electro-hydraulic servo system of the slitting machine.

The slitting machine cuts the metal coil into strips of various widths required, and then collects the strips into small rolls for use in the next process. It is indispensable for the fine cutting of transformers, motor occupations and other metal strips. device. The materials used for the primary slitting are tinplate, galvanized iron, silicon steel sheet, cold rolled strip, stainless steel strip, aluminum strip, steel strip and the like.

As you know about slitting machines, there are many ways to control the electro-hydraulic servo system of the slitter, and the system signals can be transformed by different methods. Let's take a look at the details first.

1. This signal conversion method is mainly accomplished by a servo valve proportional valve. The transformation process is the digital quantity generated by the computer. First, it is converted into analog quantity by the digital-to-analog converter, and then the analog quantity is used to control the current to make it act on the input end of the servo valve or the proportional valve. In this way, the reaction signal is converted into a digital quantity into the computer by the analog converter in the opposite way.

2. High speed switch valve method

The signal conversion process thus completed is also very simple. First, the high-speed reciprocating torque motor is used to drive the open-closed on-off valve, and the operation is lost. Then use the digital signal output from the computer to control the on-off valve. In this case, the switch will open and close the two operating conditions. When the response signal is digitally transmitted back to the computer, a conversion process is completed.

3. Stepper motor method

The stepper motor method must use the stepper motor manipulator, and the signal is transformed by it. The pulse number determines the rotation angle of the stepping motor, the pulse frequency determines the rotation speed of the stepping motor, and the rotation angle of the stepping motor is converted into the opening of the valve, that is, the digital flow valve.

All of the above methods are windshields that can be used to complete the transformation of the signal of the slitter system. Which one is selected in detail depends on the actual situation.
