Rebar splice of upset forging parallel thread system:
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
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
Upset forging parallel thread machine
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.
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.
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.
