Automatically Mechanical Rebar Processing Machine Produce Parallel
Specifications of Automatically Mechanical Rebar Processing Machine
Produce Parallel Thread
The upset forging parallel thread machine contains one rebar
threading machine(GZL-45) and one upset forging machine(GD-150) and
an oil pump. They work together with couplers for the connection of
rebar whose diameter is between 12mm and 40mm.
Fully-automatic forging machine is a parallel-threaded mechanical
splicing system designed for the connection of concrete reinforcing
bars from Ø 12
to 40 mm.
Designed and manufactured in compliance with ACI 318, IBC 2006, BS
8110, Eurocode 2, DIN 1045.

The end of the reinforcing bar is sawn square.
2. Cold forging
The sawn end of the reinforcing bar is then enlarged by a patented
cold forging process. The core diameter of the bar is increased to
a pre-determined diameter.
Finally, the thread is mechanically cut onto the enlarged end of
Easy connection by bar rotation until full thread engagement.
Parallel thread : No risk of thread mis-match. No risk of
Even when both bars cannot be turned, this system uses a standard
coupler: The coupler is fully engaged onto the extended thread of
the connecting bar. The assembly is simply completed by butting the
bars end to end and screwing back the coupler onto the first bar
until full engagement. lock-nut to maintain the second bar in
When the bars cannot be brought butt to butt (as it may happen in
cages manufacturing), Bridging splices are the answer. Both bars
are threaded with a standard thread, and a “Bridging Assembly Set”
is used to connect them.
When there is a need to splice bars of different sizes, it is
allowable in most cases to reduce the size of the larger bar and to
use a standard coupler. However we also proposes special transition
couplers that conveniently avoid the difficult task of planning in
advance the need of transitions.
A convenient alternative to hooked bars to provide end anchorages
in congested areas. Standard anchorage heads are circular and have
a net bearing area of 4 times or 9 times the cross-section of the
bar, but can also be made to order in other shapes or dimensions to
fit the application requirement.
For composite construction where concrete reinforcement bars must
be welded to structural steel, use weldable couplers, which are
specially made from low carbon steel and which have a large chamfer
for bevel welding.
