Advantages:
Bar-break feature guarantees fully ductile elongation.
No reduction of the bar cross-section area.
Material of the rebar coupler is No.45 steel.
Working principle:
1,First,We use GQ50 rebar cutting machine to splice up the end of rebar.
2,Secondly,we use Upset Forging Parallel Thread Machine (BDC-Auto1 Machine) to forge the end of rebar.
3.Third, we use Parallel Thread Cutting Machine (LW-I500 Machine) to thread the ends of the rebar which have been forged.
4.Fourth,an upsetting coupler is used to link the two ends of rebar in parallel thread.
