Introduce the extrusion process of aluminum profile extrusion machine - advantages and disadvantages of reverse extrusion
Today, the editor compiled a piece of information about reverse extrusion of aluminum profile extrusion machines. Reverse extrusion is one of the two extrusion methods used in aluminum profile extrusion machines. Today, we will first understand the advantages and disadvantages of this extrusion method, and further understand the aluminum profile extrusion equipment.
Introduce the extrusion process of aluminum profile extrusion machine - advantages and disadvantages of reverse extrusion
Advantages of reverse extrusion of aluminum alloy extruder:
1. There is no friction between the billet and the extrusion cylinder. The squeezing pressure remains constant throughout the entire stroke range of the squeezing rod. At lower temperatures, materials can be extruded with higher extrusion coefficients.
2. The metal deformation is uniform, and the microstructure and mechanical properties of the extruded product length are basically the same.
3. The waste material such as pressure residue is significantly reduced and the yield is high; Large ingots can be used to improve equipment efficiency and production continuity.
4. Long service life.
Disadvantages of reverse extrusion of aluminum alloy extruder:
1. The extrusion cylinder of the aluminum profile extrusion machine is movable, so choosing a dedicated reverse extrusion cylinder is relatively expensive.
2. The surface quality of aluminum produced by aluminum profile extrusion machines is relatively low.
3. The reverse extrusion cycle is long, and the outer diameter of the extruded aluminum is limited by the strength of the hollow extrusion rod.
4. Difficulty in loading and unloading molds, long auxiliary time
