In the man-machine interface and PLC application in automatic car coarse on the cylindrical rotor

One: the background of the 21st century, Chinese economy is developing at an astonishing speed make attention, should the need of modernization construction, leading to a huge increase in demand for motor, the amount of investment, attracted the domestic and foreign merchants and subsequently led to the rise of motor equipment sales and manufacturing automatic rough turning machine is processing the cylindrical rotor motor rotor of special equipment, at the request of shenzhen fine horse automation equipment co. , LTD. , the design integrates the rough turning machine, the cylindrical rotor rough turning machine is suitable for the cylindrical rotor fan motor, air conditioner motor, washing machine motor of cast aluminum rotor induction motor, such as coarse car. The following detailed introduces the rough turning machine characteristics of the cylindrical rotor machining process, and need to pay attention to problems. Two: the electrical characteristics of the automatic car coarse mechanical and electrical control system adopts the cylindrical rotor in DOP - A57GSTD humanized man-machine dialogue interface and DVP - 32 es00r2 programmable controller as the control center, controlled by hydraulic system, a complete set of equipment includes hydraulic motor, the spindle drive motor 1, schedule control valves (1 Dual electric control) By control valves (1 Single electronic control) Electromagnetic valve, plunger (1 Dual electric control) , one discharge solenoid valve, Single electronic control) , one feeding solenoid valve ( Dual electric control) 。 : equipment specification is as follows: the rotor diameter rotor product Φ 30 ~ 80 mm thick: axis of 10 to 60 mm diameter: Φ 8 mm cutting quantity: 0. 1 to 0. 8 mm cutter: welding knife hydraulic motor: 30 l spindle drive motor 2 HP, 3 HP use power: three-phase AC380V/( 50/60) HZ appearance size: 1000 x700x1280mm 3: equipment processing the rough turning machine is divided into the cylindrical rotor manual, semi-automatic and fully automatic three work modes according to different machining process for the rotor. Manual operation process manual operation is mainly applied to debug the mould, the normal production without the manual operation. Manual operation can be finished loading, stroke, thimble, the butcher, the discharge of their action, the manual operation in the system menu screen man-machine interface as shown in figure 1, select manual control on button component into manual control in picture below in figure 2, the manual control screen button to select different function components to complete the manual action, type the type of button component selection is to keep the button to complete the design of the program. The manual process to write PLC controller program need to pay attention to the butcher and the plunger in the return process sequence and interlock to prevent damage to intervene with cutting tools, should be performed in accordance with the following the correct order: knife back first, travel, thimble back again, you do not need to add any interlock between other actions. Semi-automatic process semi-automatic process is manual feeding unit, the process flow is mainly applied to processing production product, equipment and processing after completing the first product no longer return to the initial steps for machining of the next. Automatic process: automatic process is in the process of normal production without artificial feeding by the rough turning machine automatically completed by expected unloading process on the motor rotor continuous processing of turning process, the specific process is as follows: the above flow chart of semi-automatic and fully automatic central plains state of point for back, trip back, the butcher return, return discharge. Execution of semi-automatic and fully automatic process in the first place in the man-machine dialogue interface on the above 3 on selecting the corresponding mode button function components, then switch to the run screen below 4 equipment is up and running or press the fuselage of the external start button. Four: PLC controller programming, and the man-machine macro instruction applied in the process of programming, it is important to note of semi-automatic and fully automatic process execution process, if the device fails to press the emergency stop button, after press the stop button, discharge institutions all other institutions to restore the original zero, but need to pay attention to in the process of back knife back first, travel, thimble back again, can appear otherwise movement interference damage the cutting tool. Whether any of these technology, when the process of mode conversion between, knife, stroke, thimble, unloading all return to original state back to automatic. In the process of mode conversion, since it is man-machine interface is used to compile the switch component, using the button on macro instructions to complete the switch interlock between the components. The diagram below 5 ~ 7: the macro instruction of figure 5 is to choose the manual control mode, automatic, semi-automatic mode selection button is reset. Figure 6 huge set of instructions is to choose the automatic operation mode, manual and semi-automatic mode selection button is reset; Figure 7 images of seven macro instruction is to choose the semi-automatic operation mode, select button to reset the manual and automatic mode; Programmable controller of semi-automatic and fully automatic program for instructions on using the step ladder diagram to finish, so that reduces the order of the ladder diagram interlock, implementation and debugging is easy. In the process of system operation, when the abnormal sensor, motor over-current file is not in place or origin return does not reach the designated position, will automatically prompt alarm and stop on the man-machine interface, the mechanic operation in accordance with the corresponding prompt to specify the location to do fault check, troubleshooting, restore normal operation of equipment.
Every day of the year, there is some city or town in the world that is changing over to for plc controller price.
Our vision serves as the framework for our plc manufacturers and guides every aspect of our business by describing what we need to accomplish in order to continue achieving sustainable, quality growth.
