Lost foam casting process monitoring system

Abstract

The invention provides a casting process monitoring system based on lost foam casting. The casting process monitoring system comprises a RFID (Radio Frequency Identification) tag, a casting line RFIDdevice, a cooling line RFID device, a casting information acquisition module, a PLC (Programmable Logic Controller), a photoelectric converter, a wireless communication module and an industrial control machine, wherein the casting line RFID device comprises a RFID reader-writer and a proximity switch which are arranged on each casting line and are opposite to the RFID tag; and the cooling line RFID device comprises a RFID reader-writer and a proximity switch which are arranged on a cooling line and are opposite to the RFID tag. The identification of sandbox information is realized by a radio frequency identification technology. The data exchange between the PLC controller and an MES system is realized by using the photoelectric converter. The data transmission between the MES system and the industrial control machine is realized by using the wireless communication module. The dynamic display of the position of a sandbox during movement of the sandbox on the casting line is realized through the industrial control machine, and the casting state, casting time and casting rate of the sandbox are displayed in real time. Through the adoption of the casting process monitoring system, thetime cost is lowered; the casting rate is increased; and a basis is laid for the whole life cycle of the product.

Description

technical field [0001] The invention relates to the lost foam casting technology, in particular to a monitoring system for the lost foam casting casting process. Background technique [0002] During the lost foam casting, the operator and the casting machine are located on the top of the sand box. When the next round of casting is performed after the current ladle is cast, it is necessary to manually check which sand box has not been cast, and then move the casting machine to the corresponding position. , this process consumes a lot of time, thus reducing the casting rate. In addition, although the existing lost foam casting industry has established a product traceability system from pre-foaming to before casting, due to the harsh casting environment, it is impossible to effectively monitor the casting process and establish a full life cycle traceability of the product. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides ...
