Extrusion principle of aluminium profile extruder

1. Extrusion principle of aluminum profile

Aluminum profile extrusion is a plastic processing method for external force exerted on metal billet in container (extrusion cylinder) to make it flow out of a specific die hole and obtain the shape and size of the required section.

Two. The composition of aluminum extrusion press

Aluminum extrusion machine is made up of machine frame, front column frame, expansion column, extrusion cylinder and hydraulic system controlled by electricity. Besides, it is equipped with die base, thimble, scale plate, slide plate and so on.

Three. Classification of extrusion methods for aluminum profiles

According to the type of metal aluminum extrusion cylinder, the state of stress and strain of aluminum extrusion, lubrication, extrusion temperature, extrusion speed, die types or structure, or the number of blank shape, the shape of products or the number of different, can be divided into forward extrusion, backward extrusion method. (including the plane deformation of axisymmetric deformation of extrusion, extrusion, extrusion of general 3D deformation) lateral extrusion method, glass extrusion method, hydrostatic extrusion method, continuous extrusion method etc..

Four, forward hot deformation extrusion

The deformation of extrusion method through specific mould is most heat hot deformation of aluminum production enterprises (flat die, die, mould) to get the desired shape. This is the only aluminum, aluminum production method of gold Haochun aluminum so far taken!

The forward extrusion process is simple, the equipment requirements are not high, the metal deformation ability is high, the production range is wide, the performance of aluminum material is controllable, the production flexibility is large, and the tooling is easy to maintain and repair.
