Background

Extrusion is a plastic working method for obtaining the required cross-sectional shape and size by applying external force to the metal blank placed in a container and making it flow out from a specific die hole, and is mainly used for producing the bars, pipes and profiled bars of stainless steel, nickel-base high-temperature alloy and refractory alloy. Hot extrusion is the earliest extrusion technology used in several extrusion processes, and is used to perform various extrusion forming on metals at hot forging temperature by virtue of the characteristic of good plasticity of the material. At present, hot extrusion is mainly used for manufacturing long pieces, profiles, pipes, bars, various machine parts and the like with common equal sections. Hot extrusion can not only form nonferrous metals and their alloys, low and medium carbon steels, etc. with good plasticity and relatively low strength, but also form high carbon and high alloy steels with relatively high strength, such as special structural stainless steel, high speed tool steel, heat resistant steel, etc.

Traditional extrusion die all uses the manpower to carry out opening and shutting of mould, because the interior section bar deformation in-process of extrusion die can produce a large amount of heats, leads to mould bulk temperature higher, just can carry out artifical drawing of patterns after need waiting for the mould cooling, leads to the drawing of patterns time extension.
