The steel rebar upsetting machine utilizes the principle of hydraulic cold heading to cause plastic deformation at the end of the steel bar, increasing rebar upsetting machine diameter by 4 to 6mm, and then processes the threads. Make the actual cross-sectional area after processing the threads larger than the original cross-sectional area of the reinforcing bar, thereby enhancing the tensile strength of the joint. After being upset by the upsetting machine, the strength of the base material of the steel bars is much higher than before, making rebar upsetting machine suitable for some projects with strict process requirements.

The steel bar ends are upsetting. After upsetting, the strength of the steel bar base material is enhanced, the tensile strength is increased, and the safety of the project is improved.
The operation is simple and easy. This kind of rebar coupler machine runs automatically, saving labor and reducing workers' fatigue. rebar upsetting machine can be used for continuous processing and production.
A rebar forging machine operates on the principle of cold upsetting (cold heading), a precision metal forming process performed at room temperature. By applying extremely high hydraulic or mechanical pressure through a powerful ram, the rebar cold forging machine plastically deforms the end of the rebar, forcing the steel to flow into a specially designed die. This significantly enlarges the diameter (typically by 4–6 mm) while simultaneously compacting the grain structure, substantially increasing the density and strength of the forged "upset" end — often making it stronger than the original rebar itself. The resulting enlarged and strengthened end is then parallel-threaded and connected using high-performance mechanical couplers, achieving a full-strength, reliable, and durable connection that meets or exceeds the tensile strength of the parent rebar material, making it an ideal solution for critical structural reinforcement in modern construction.
The net cross-sectional area of the upset steel bar after thread cutting is still larger than the original cross-sectional area of the steel bar.
Rebar upsetting machine is all the threaded joints after upsetting fracture at the base metal in the tensile test.
Rebar forging machine enables high production efficiency.
