Product Description

Upset forging parallel thread rolling system:

1.Description of upset forging parallel threading machine:
The thread coupler works together with upset forging machine(GD-150) and rebar threading machine(GZL-45) for the connection of rebar whose diameter is between 12mm and 40mm.

2.Working principle of machinery:

First, we use GD-150 to forge the end of rebar.

Second, we use the GZL-45 to thread the end of rebar.

Third, we use the thread 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.
