Basic principle of extrusion forming of aluminum profile extrusion press machine plant line
1、 Basic principle of aluminum alloy profile extrusion
Aluminum profile extrusion is a plastic deformation production and processing method. It can increase external force on the metal blank (extrusion barrel) placed in the container to separate it from the special cavity and obtain the desired shape and specification.
2、 Composition of aluminum profile extrusion press machine plant line
aluminum profile extrusion press machine plant line is composed of motor shaft, front column frame, lifting column, extrusion forming cylinder and hydraulic transmission system under electric control. It is also equipped with die base, thimble, scale plate, double rocker, etc.
3、 Classification of extrusion forming methods of aluminum alloy profiles
According to the different types of metal materials in the aluminum alloy profile extrusion forming cylinder, stress-strain curve, aluminum alloy profile extrusion forming direction, wetting condition, extrusion forming temperature, extrusion forming rate, type or structure of die shell, shape or quantity of blank, shape or quantity of products, it can be divided into forward extrusion forming method and reverse extrusion forming method, (including plane figure variable extrusion, central symmetrical deformation extrusion and general three-dimensional deformation extrusion) side extrusion, laminated glass wetting extrusion, hydrostatic extrusion and continuous extrusion.
4、 Positive thermal deformation extrusion
