Product Description
Cold Forging System
We have reducing couplers, upset forging parallel thread connection system and rib peeling roll stamping connection system, they can be used for the connection of rebars with different diameter(from 12mm to 40mm).
It can meet the requirement of two rebar with different diameter.
Handy operation and quick link.
High efficient.
High adaptability.
Environmental protection.

Upset forging parallel thread  machine
1.Description:
The upset forging parallel thread machine contains one rebar threading machine(GZL-45) and one upset forging machine(GD-150), they work together with couplers for the connection of rebar whose diameter is between 12mm and 40mm.

2.Working principle:
First, we use GD-150 to forging the end of rebar.
Second, we use the GZL-45 to threading the end of rebar.
Third, we use the coupler to link the two ends of rebar.

3.Advantages:
1, Adopts upset forging parallel thread connection technology;
2, Wide working range: Adaptable for 12mm-40mm same diameter, different diameter, bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706 standard.
3, High strength: Stronger than the reinforcement bar and guarantees bar break under tensile stress(tensile strength of connection point =1.1 times of connected bar's specified tensile strength). It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003, JG171-2005.
4, High efficiency: Upset forging and threading one joint only needs no more than one minute, and handy operation and quick link.
5, Environmental protection and economy profit: No envirement pullution, can work all day, not affected by weather, economize energy source and bar material.
