China Construction Equipment Upset Forging Thread Rolling Machine for Rebar Coupler

Changzhou Jianlian Reinforcing Bar Conjunction Co.,Ltd

1.Upset Forging Thread Rolling Machine for Rebar Coupler
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.

3.Working principle of upset forging thread machine:
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.
4.Advantages of machines and rebar couplers:
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.
