The straight thread rebar upsetting machine is used for mechanical splicing of steel reinforcing bars at first stage. After extruding and upsetting with the rebar end, the cross-sectional area gets bigger, it is suitable for the ∅16-∅32mm, Ⅱ and Ⅲ grade building reinforcement.

It adopts the technology process of extrusion deformation at normal atmospheric temperature so as to improve rebar tensile strength, and keep it’s mechanical properties. Small design of machine structure, the integration of chuck and the die cavity simplifies machine overall structure. Furthermore, it ensures rebar upsetting end is concentric with the base metal, also improves the working efficiency.
