Upset forging parallel thread system
A) GD-150 rebar end upset forging machine, B) GZL-45 rebar threading machine, C) Rebar coupler (diameter=12mm-40mm) Advantages
1.adaptable for Φ12mm-Φ40mm same diameter, different diameter of rebar, bending, new and old, advance covered up rebar of GB1499,BS4449,ASTMA615 or
ASTMA706 standard. 2.stronger than the reinforcement bar and guarantees bar break under tensile tests (tensile strength of bar joint =1.1times of bars specified tensile strength). 3.upset forging and threading one joint only needs no more than one minute, and handy operation and quick link. 4.no environment pollution, can work all day, not affected by weather, economize energy source and bar material. Working principle
1,First, we use upset forging machine (GD-150) to forge the end of rebar. 2,Second, we use threading machine (GZL-45) to thread the ends of the rebar which have
Been forged. Third,a coupler is used to link the two ends of rebar
Rib peeling roll stamping system
A) Rib peeling roll stamping machine
B) rebar coupler (diameter=16mm-40mm)
Advantages of the products: 1High tensile strength and the strength reach GradeⅡ (Equal to the connected rebar); 2.Rib peeling completed by one-time steel bar nipping, roll screw thread with fast speed; 3.Highly automatic and easy to operate; 4.Roll stamping after steel bar rib peeling, with good shape of thread, high precision
and conformed diameter size; 5.Few roll head specifications, wider scope of steel bar machining, Only one set machine
canprocess16-40mm screw thread steel bar; 6.Easy to adjust, when rolling steel bars of different specifications, adjustments can be
made without taking apart rolling head, provided that the screw pitch are the same.
