Rebar Upsetting Technology
1) Cutting:
The end of the reinforcement bars is sawn square.
2) Cold Forging:
With the help of patented cold forging, the sawn end of the reinforcing bar is then enlarged. With this the core diameter of the bar is increased to pre determined diameter.
3) Threading:
An ISO standard metric thread is then cut
Reinforcement by Coupler's System,
This machine is the preparative machine for rebar connection in construction work. Its main function is to forging the end part of rebar to raise the rebar area and therefore enlarge the strength of rebar end.
Upset parallel threaded couplers are suited to projects which require high volumes of couplers. They produce a full strength joint in the rebar connection. 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.
