Description

This rebar threading machine(gzl**5) works together with upset forging machine(gd***0) and couplers for the connection of rebar whose diameter is between *2mm and *0mm. Working principle: First, we use gd***0 to forging the end of rebar. Second, we use the gzl**5 to threading 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\&#**9;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.
