The couplers work together with the rib peeling roll stamping machine for the connection of rebar whose diameter is between 16mm and 40mm.

Principle:
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.
