This machine is the preparative machine of rebar connecting in
construction. Its main function is upsetting and thickening the end
part of rebar to raise the rebar area.
1: The ends of the bars to be joined are cut square and enlarged by
cold forging to increase their core diameter and so ensure that the
joint is stronger than the bar. The couplers are usually supplied
attached to the reinforcing bar.
1. First use the upsetting machine to thicken the end of the rebar
2. Then use the steel bar threading (cut) machine to make thread on
the end of rebar
3. Connect the two rebar end with the upsetting rebar couplers.
