parallel thread coupler

详情

The coupler works together with upset forging machine(GD***0) and rebar threading machine(GZL**5) for the connection of rebar whose diameter is between *2mm and *0mm.

Working principle:
First, we use GD***0 to forge the end of rebar.
Second, we use the GZL**5 to thread the end of rebar.
Third, we use the coupler to link the two ends of rebar.

Advantages:
1, Adopts upset forging parallel thread connection technology;
2, Wide working range: Adaptable for *2mm**0mm same diameter, different diameter, bending, new and old, advance covered up rebar of GB ***9, BS ***9, ASTM A**5 or ASTM A**6 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 JGJ*******3, JG*******5.
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.
