Changzhou Jianlian Reinforcing Bar Conjunction Co.,LtdWe have reducing couplers of upset forging parallel thread connection system and rib peeling roll stamping connection system, they can be used for the connection of rebars with different diameter(from 12mm to 40mm).
It can meet the requirement of two rebar with different diameter.
Handy operation and quick link.
1.The couplers work together with the rib peeling roll stamping machine for the connection of rebar whose diameter is between 16mm and 40mm.
:All process is completed by one machine.
First use the rebar rolling thread machine to process the rebar to make parallel thread;
Second, use the coupler to link the two bars. Features:1, Tensile strength of connection point is equal to connected bar's specified tensile strength;
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, Rolling wheel has long service period, low additive cost of connector;
6, Few roll head specifications, wider scope of steel bar machining, Only one set machine can process 16mm-40mm screw thread steel bar;
7, 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.
