software part of the electrical control system of valve lathe
In the electrical control system,the structural design of the software part is a very critical content.In addition to important modules such as industrial control computers,power modules,motor modules,etc.,components such as sensors,frequency converters,and grating rulers cannot be ignored.First,the power module is determined.As the core component for converting the current form,the frequency converter in the power module is the main component.This component can be used to adjust the current frequency.After converting AC power into DC power,on this basis,the inverter in the power module will further convert DC power into AC power and provide it to the valve lathe.According to this principle,the power module can be divided into non-adjustable power module and adjustable power module according to the power supply call.Among them,adjustable power supply is more common,and most power modules in valve lathes are of this type.The second is the design of the motion controller.For the electrical control system of the valve lathe,the motion controller is an extremely critical content.The running speed and stable operation of the motion controller are very important.Third,the selection of the frequency converter.In addition to the above two aspects,the electrical control system of the valve lathe contains two inverters.It is necessary to pay attention to the current problem of the inverter.According to the actual situation,the process parameters of the motor,inverter and other aspects should be technically designed.
Accelerating the development of composite valve machine tools,improving the concentration of processes,and intensively processing the process chain can improve the efficiency of multi-variety single pieces and small and medium batch processing,and is also conducive to the stability of processing accuracy.Composite valve machine tools can reduce the waiting time and multiple loading and unloading time caused by the conversion of processes between different valve machine tools.
the current situation of valve drilling machine technology abroad
At present,most of the valve drilling machines produced abroad have widely adopted the 32 system,while the valve drilling machines produced domestically are mostly 16 systems due to the restrictions of purchasing technology.This makes the domestic valve drilling machines inherently insufficient in function,and there is a clear gap compared with foreign valve drilling machines.Whether it is a machining center or a CNC turning center,this type of new CNC equipment has shown strong productivity that can meet the needs of many complex parts in mass production.Generally,it has 4~5 axis linkage and can perform multi-faceted processing in one clamping.Under program control,the spindle can be automatically converted between vertical and horizontal positions.
