Rebar splice of upset forging parallel thread system:
Principle:
First, use the machine to make the thread on the end of rebar.
Second, use the bar splice to link the two ends of rebar
Advantages:
1, The bar splice can be used to link rebar whose diamter is between 12mm and 50mm;
2, The tensile strength of the bar splice can be 1.1 times of the steel bars;
3, Especially, the exceed strength(special material) coupler's tensile strength is more than 800Mpa

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.
