Wholesale Price Threaded Rebar Couplers - GZL-45 Automatic Rebar Thread Cutting Machine – YIDA

As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:

1, Wide working range: adaptable for Φ12mm-Φ50mm same diameter, different diameter,

bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706 standard.

2, High strength: stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of bar joint =1.1 times of bar’s specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003, JG171-2005.

 3, High efficiency: upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.

4, Environmental protection and economy profit: no environment pollution, can work all day, not affected by weather, economize energy source and bar material.

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

This machine is used to cut the thread for rebar end after cold forging.

Processing Machine

1. (BDC-1 Machine )Rebar End Upset Forging Parallel Thread Machine

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.

Working principle:

1,First,we use Upset Forging Parallel Thread Machine (GD-150 Automatic Machine) to forge the end of rebar.

2,Second we use Parallel Thread Cutting Machine (GZ-45 Automatic Thread Machine) to thread the ends of the rebar which have been forged.

3.Third,a coupler is used to link the two ends of rebar in parallel thread.
