Extrusion system and extrusion method of LCE engine cylinder body

Abstract

The invention relates to an extrusion system and an extrusion method for an LCE engine cylinder body. The system comprises a die with an extrusion pin structure; the extrusion pin structure is connected with an extrusion pin machine through an oil pipe; the extrusion pin machine is connected with a die-casting machine through signals; the extrusion pin machine takes a pressurization signal of thedie-casting machine as an action instruction; the extrusion pin machine is connected with a PLC control system. when the die-casting machine gives out the pressurization signal, the extrusion pin machine receives the instruction and sends out an action signal, and the extrusion pin machine conducts extrusion immediately. the actual pressure is monitored through an oil pressure gauge while extrusion action is performed, and actual temperature of an extrusion pin is monitored through a temperature sensor; then data is output to a quality detection end, and is monitored in an interval set by quality detection; an alarm is given when the data exceeds a range; and the data is checked on a mobile phone in real time through the Internet cloud. By adopting the extrusion system and the extrusion method, state of the extrusion pin can be effectively monitored in real time; problems can be found in time; rejected products are reduced; and production cost is reduced.

Description

technical field [0001] The invention relates to an intelligent control and detection system, in particular to an extrusion system and an extrusion method of an LCE engine cylinder, belonging to the technical field of casting technology. Background technique [0002] At present, due to the continuous improvement of customers' requirements for the internal quality of die-casting products, but based on the existing die-casting process, it is difficult to achieve the requirement of zero porosity of the product, and only partial zero porosity can be considered, so local extrusion occurs technology. Nowadays, the local extrusion technology is widely used in the foundry industry. However, behind the increasingly mature extrusion technology, the failure of the extrusion pin (extrusion failure, insufficient extrusion depth, explosion, etc.) often occurs. If Failure to detect in time visually will lead to poor product batches and increase the company's huge costs. Contents of the i...
