There are many methods of pipe bending, and there are different bending equipment accordingly. Among various methods, bending is the most commonly used bending method, and the most commonly used equipment for bending is pipe bending machine. Therefore, pipe bending machine is the main equipment for pipe bending processing. The medium frequency heating hydraulic pipe bending machine is mainly composed of mechanical device, hydraulic system, medium frequency heating system, PLC control system, cooling system, etc. The mechanical device is mainly composed of clamping device, trolley propulsion device, guide wheel device and rocker arm rotation device. So what is the overall hardware structure design of the pipe bending machine Embedded Measurement and control system
The whole hardware system of the pipe bending machine takes the embedded microprocessor as the core and transmits instructions to the machine tool system through the man-machine interface. The motion control card is equipped with intelligent control software such as fuzzy control and parameter optimization, and the corresponding communication program. It can form various closed-loop control systems with the host computer. The system drives the servo motor driver through the motion control card to drive the motors of each control shaft to realize feeding, material transfer, angle processing and other actions.
On the other hand, the actions of main clamping / loosening, auxiliary clamping / loosening, auxiliary propulsion and core pushing / pulling of pipe fittings are controlled by I / O card. The I / O control card controls the controller of each auxiliary action and various state sensors of the machine tool, receives the commands and data from the embedded microprocessor through the system window, completes the setting and modification of parameters and the switching value control of auxiliary action, and feeds back various working conditions and state values of the machine tool, as well as various alarm information. The information exchange between the microprocessor and the I / O control card is completed through the peripheral component expansion interface (PCI) bus, which is inserted into the PCI bus slot of the processor.
