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. 2. (GZL-45 Auto Machine )Steel bar Parallel Thread Cutting Machine

Rebar diameter range:	φ16－φ40
Threading cutting speed	32r/min
Backing speed	64r/min
Electric motor power:	2.4/3KW
Cutting head movement distance:	150mm
Out dimension(mm):	1325×570×1070mm

This machine is used to cut the thread for rebar end after cold forging.And it can also be used for thread rolling as well as bolt length above 500mm,unlimited length bolts. 3.Rebar Couplers Advantages:

l Bar-break feature guarantees fully ductile elongation.l 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 (GD-150 Automatic Machine) to forge the end of rebar. 3.Third, we use Parallel Thread Cutting Machine (GZ-45 Automatic 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. Assembly Benefit 1. No torque wrench required. 2. Assembly validated by visual inspection. 3. Manufacturing of couplers under strict quality plans. 4. Standard ISO Parallel Metric Thread design. Remarks: According to Chinese standard GB 1499.2-2007, for rebar HRB400:Tensile strength≥54t0Mpa,Yeild strength≥400Mpa; for rebar HRB500:Tensile strength≥630Mpa,Yeild strength≥500Mpa. The upset forging parallel thread connection technology can not only be used for the connection of HRB400,but also for other rebar, such as HRB500, whose tensile strength is higher than 700Mpa and so on.
