40MN Aluminum Extrusion Machine Hydraulic Impact Analysis And Optimization

Metal extrusion in industrial production occupies the position of play a decisive role, is.the foundation for industrial development process. Along with the aluminum alloy in the construction, automotive, rail transportation, aerospace and other industries developed rapidly, aluminum alloy processing in the national economy is becoming more and more important role. Large metal extrusion machine manufacturing level is a measure of a country’s level of industrial development is one important symbol. Europe and the United States have attached great importance to the development of large-scale metal extrusion press.Heavy metal extrusion machine exhaust action switch fast motion components, quality, power and inertia big, complex hydraulic system. Based on these characteristics in the extruder exhaust process of the occurrence of strong hydraulic shock and vibration.Heavy metal extrusion machine has high working pressure, volume, loading also accumulate large elastic potential energy, the unloading moment on the pipeline of the hydraulic system interface, hydraulic valve and the compressor produces very big effect.This is a company40MN double moving forward aluminum alloy extrusion machine movement principle, main structure are introduced, and the extrusion machine exhaust action of the hydraulic impact is analyzed and the main cylinder unloading process simulated by AMESim, according to the results, put forward the reform plan.After the transformation of the40MN extrusion machine the actual operation of the system shows that, extruder exhaust action and the extrusion end main cylinder pressure unloading hydraulic impact significantly improved.
