With the rapid development of the construction industry, steel bar processing construction machinery dominated by steel bar bending, steel bar straightening and cutting has also flourished and developed rapidly in recent years. Among them, the CNC steel bar bending machine adopts full servo control, can process 7.5 tons of steel per day, and has a program library with more than 500 kinds of graphics pre-stored, and does not need to occupy a large area, only one worker can work, which is more than the original manual operation. The method improves the efficiency by nearly 40 times, greatly improves the production efficiency and reduces the labor cost.
     
The fully automatic hoop bending machine equipped with Elias servo products can achieve a single machine production efficiency of 8 to 10 times that of manual and semi-automatic hoop bending machines, which is nearly 40 times more efficient than the original manual method. Electrolys servo motor has 3 times overload capacity, which can meet frequent start and stop control, and the servo response speed is fast, which can meet high-speed operation. Electrolys servo control precision is high, wire feeding servo fixed length accuracy can reach ±1mm bending servo bending accuracy can reach ±1°. In addition, the wire feeding servo adopts the full closed-loop control of the external encoder, which overcomes the error caused by the slipping of the steel bar.
