Classification of extrusion technology

By yintuo at 2021-02-24 • 0 collector • 243 pageviews

Extrusion molding is often used in the production of pipes. From an international point of view, there have been more in-depth studies on pipe extrusion molding of soft metals such as Mg, Al, Cu, etc. About 1797, the British Braman designed it. The world's first mechanical extruder for lead extrusion.

From the late 1950s to the early 1980s, advanced countries such like Europe, America, Japan and other advanced countries have rapidly increased the demand for aluminum alloy extrusion profiles for construction, transportation, power, electronic appliances, and promoted the rapid development of aluminum alloy pipe extrusion technology.

Through continuous technological improvement, the extrusion technology has evolved from manual to mechanized, semi-continuous, and further developed to continuous, and from the extrusion of soft metals to the extrusion of hard metals.

According to the stress and strain state of the metal in the extrusion cylinder, the extrusion direction, the lubrication state, the extrusion temperature, the extrusion speed, the type and structure of the die, the shape or number of the blank, the shape or number of the product, etc. the extrusion The classification method is also different. These classification methods are not static, many classification methods can be used as a subdivision of another classification method. For example, when dividing according to the extrusion direction, it is generally considered that there are three types of forwarding extrusion, reverse extrusion, and lateral extrusion. The forward extrusion and reverse extrusion can be further divided into planes according to the deformation characteristics. Deformation extrusion, axisymmetric deformation extrusion, general three-dimensional deformation extrusion, etc.
