machine is one of the important equipment, non-ferrous metal castings, with wide application in the modern industrial manufacturing.
Die casting machine of anomaly detection and control is not just about safety and service life of die casting machine, more about die casting the personal safety of workers, is the most important link in the design of die casting machine control system.
In this paper, the die casting machine of the anomalies are analyzed.
Die casting is modern metal processing technology developing rapidly in an efficient, less cutting metal forming precision casting method.
The die casting machine is adopted the die casting method of molten metal in the pressure under the action of hydraulic shot into the mold cooling molding, open mold after by a series of solid metal casting foundry machinery industry.
Along with the development of the automobile manufacturing, such as in the Chinese market, and related die casting aluminum alloy cylinder engine development is swift and violent, and about the quality of the casting quality are also put forward higher requirements.
While traditional die-casting machine control system adopts relay control, microcomputer control mode, etc.
But control relay control, microcomputer controls tend to have low efficiency, poor reliability and anti-interference ability weak and late difficult problems such as maintenance, someone put forward a kind of based on PLC (
Programmable logic controller)
Die casting machine control system design, improve the control reliability and efficiency.
However simple PLC control system is not easy to realize the scene monitoring and process parameters of die casting machine set up and modify, in view of the technological parameters of die-casting machine control system is more, and human-computer interaction parameter set up and modify, wisely Peng Ji carried out such as die casting machine control system based on PLC and touch screen technology, can solve the problem of the parameter setting of human-computer interaction.
In order to improve the integration degree of integration of production management, realize the many sets of die-casting machine production process parameters of centralized control system design, so as to realize the centralized management of many sets of die-casting machine, real-time monitoring.
On the other hand, in order to improve the quality of die casting, the performance improvement of convolution model institutions and precise control of injection process is very necessary.
Aimed at the improvement of the flash problem and mold the improvement of mechanical properties has been very good study.
Never studied the die-casting machine system and good results have been achieved, but in view of the die casting machine system anomaly detection and control of the article is missing.
Ongoing die-casting machine safety accident in recent years gradually to cause the attention of people to die casting.
Die casting machine of anomaly detection and control is not just about safety and service life of die casting machine, more about die casting the personal safety of workers, whether for die casting machine have the ability to anomaly detection and control is a die-casting machine whether to mark important testing standards, is also the most important link in the design of die casting machine control system.
In the whole die casting process, a slight abnormal action could bring serious harm, pose a great threat to machine and personal safety, etc.
A qualified die casting machine, when there is abnormal situation occurs, should be able to timely detect the abnormal and sends the corresponding alarm, at the same time, according to the severity of the abnormal choose whether to stop, and abnormal causes and solution is given.
need huge investment, so it is important to shop with caution.
