UPSET FORGING PARALLEL THREAD
SYSTEM
1. Description
The upset forging parallel thread machine contains :
one rebar threading machine(GZL-45)
one oil pump
one upset forging machine(GD-150)
they work together with couplers for the connection of rebar whose diameter is between 12mm and 40mm .

3. Working principle
First, we use GD-150 to forging the end of rebar.
Second, we use the GZL-45 to threading the end of rebar.
Third, we use the coupler to link the two ends of rebar.


4. What makes us successful
A. Shorten your engineering period -- the two rebars can be connected within 35 seconds;
B. Catch the highest quality -- 100% broken rebars, no safty worrying, can past any safty quality test;
C. Save rebars -- give up weld and colligation rather than our connecting methods, can save many
rebars materials.
5.Why choose JBCZ
1, High strength: the strength reach Grade I , stronger than the reinforcement bar
and guarantees bar break under
tensile stress (tensile strength of connection point =1.1 times of connected bar).
It can satisfy the requirements stipulated in the Chinese standard JGJ107-2003,JG171-2005.
2 ,Wide working range: adaptable for Φ12mm-Φ50mm 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 efficiency: upset forging and threading one joint only needs no more than one minute, and handy operation
and quick link.
4,Environmental protection and economy profit: no
environment pollution, can work all day, not affected by
weather, economize energy source and bar material.
