The slitting line is to cut metal coils into strips of various widths required, and then harvest the strips into small rolls for the next process. It is an indispensable equipment for fine cutting of transformers, motors and other metal strips. . It is mainly used for slitting and cutting materials such as tinplate, galvanized iron, silicon steel sheet, cold rolled steel strip, stainless steel strip, aluminum strip, steel strip and so on. There are many types of slitting lines. According to the thickness of the slitting plate, it can be divided into thin plate slitting line and thick plate slitting line; according to the slitting metal material, it can be divided into stainless steel slitting line, copper strip slitting line, cold plate slitting line, silicon steel Slitting lines, etc. According to the degree of automation, it can be divided into automatic slitting line and semi-automatic slitting line. Those who are familiar with the slitting line should know that the electro-hydraulic servo system of the slitting line has many control methods, and its system signals can also be transformed in different ways.
Let's look at the first in detail.
Step 1: Digital-to-Analog Conversion
This signal conversion method is mainly completed through the servo valve proportional valve. The conversion process is the digital quantity generated by the computer. First, it is converted into an analog quantity through a digital-to-analog converter, and then the analog quantity is used to control the current so that it acts on the input end of the servo valve or proportional valve. In this way, the response signal will be converted into digital quantity by the analog-to-digital converter and enter the computer in the opposite way. This method of signal conversion enables high-precision manipulation.
Step 2: High-speed switching valve method
The signal conversion process thus completed is also very simple. First, a high-speed response torque motor is used to drive the on-off valve with a fixed opening, and the operation is lost. Then use the digital signal output by the computer to control the switch valve. In this way, the switch will be in two working states of on and off. When the feedback signal is sent back to the computer in the form of digital quantity, a conversion process is completed. The slitting line can be manipulated in this way.
Step 3: The Stepper Motor Method
The stepper motor method will definitely use the stepper motor controller, and the signal is transformed by it. Among them, the number of pulses determines the rotation angle of the stepping motor, and the pulse frequency determines the speed of the stepping motor. The rotation angle of the stepping motor is transformed into the opening of the valve, that is, the digital flow valve.
The above methods are all windshields that can be used to complete the transformation of the slitting line system signal, and which one to choose depends on the actual situation. More information can be found on the official website of Bangzhou Machinery.
