Upsetting forging parallel thread system

This machine is specially for rebar connection in construction work. Its main function is to forge the rebar end part to enlarge the cross sectional area of rebar, whose design principle make the tensile strength of rebar end more stronger. The machine process the rebar diameter range: from 12mm to 40mm. RUM-40C upset forging parallel thread connection is 100% higher than steel bar material strength. After finishing rebar connection, the tensile strength can reach 700-1050Mpa, yield strength can reach 500-800Mpa.
