As an important industrial, architectural and automotive profile, extruded aluminum pipe is widely used in all walks of life. The forming methods of aluminum alloy profiles include extrusion, casting and forging. The forming methods are different for different structural shapes of aluminum alloy profiles. In order to obtain aluminum alloy profile extrusion parts with excellent comprehensive performance, many scholars at home and abroad have conducted in-depth research on the relevant characteristics of aluminum alloy extrusion. Among them, Li GuiGui has analyzed the extrusion forming rules of high-strength aluminum alloy thin-walled longitudinal rib members and studied the process optimization;
The extrusion forming of hollow aluminum alloy profile is analyzed by numerical simulation, and the simulation is verified by experiment; The extrusion process of complex aluminum profile is simulated by numerical simulation method, and the die structure is optimized; A large extrusion die for 7005 aluminum alloy was designed and its processing technology was studied; The extrusion of aluminum tube was simulated by Pro / E, and the extrusion die structure was optimized; The core stability of 6061 aluminum alloy plane split die was studied; The extrusion forming of large hollow section aluminum profiles was studied by numerical simulation; In the aluminum alloy profile extrusion simulation model, the extruded aluminum tube is mainly composed of Extruded round rod, guide hole, welding chamber, working belt, extruded profile, etc. the heated Extruded round rod enters the welding chamber through the guide hole under the extrusion force. The aluminum profile in the welding chamber is extruded into the target aluminum alloy profile through the working belt under the extrusion force.
