Product Description
 
UPSET FORGING PARALLEL THREAD 
SYSTEM


1. Description of upset forging parallel thread system

(1) GD-150 Upset forging machine
Working range: 12mm- 40mm
Motor power: 4.0KW
we use GD-150 to forging the end of rebar.

(2) GZL-45 threading machine
Working range: 12mm- 40mm
Motor power: 3/2.4KW
we use the GZL-45 to threading the end of rebar.
The tensile strength of rebar connector is not less than 627MPA, 
and the tensile strength of super coupler can be reach 800~900MPA

2.Working Principle & Specification


1. First, use GD-150 to forge the end of rebar;
2. Second, use GZL-45 to process thread on the forged end of rebar;
3. Third, use parallel thread coupler to abutting joint two threaded ends of rebar.

3. Advantages of carbon steel parallel thread mechanical rebar splice coupler

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.
