GTW8-16 Intelligent Steel Stirrup Bending Machine

Equipment Application: This fully automatic CNC steel bar stirrup bending machine utilizes imported Italian technology, developed through numerous technical reforms by our company’s technical department and extensive testing. It replaces the traditional, time-consuming, and labor-intensive, outdated method of manual steel bar processing. The machine offers numerous advantages, including energy conservation and consumption reduction, time and labor savings, safety and efficiency, and reduced labor intensity. Currently, it has reached advanced domestic standards and is the primary equipment for bending steel bars in construction projects.

  • High power: processes φ12 single-line coil, φ4-10 double-line coils.

  • Powerful intelligent functions: automatic protection, real-time monitoring of voltage and current levels, with remote control and positioning capability.

  • All electrical components adopt well-known domestic brands.

  • Hundreds of circular shapes can be pre-input; instantly retrievable during processing, saving time and labor, and graphics can be freely edited according to drawing requirements.

  • Key parts are made of special steel, ensuring long service life, low operating cost, and guaranteed processing capacity of over 1000 tons of steel.

  • High quality and affordable price, excellent cost performance.

  • Full machine servo drive and PLC control, overcoming the shortcomings of low efficiency and large errors in traditional machines.

  • Independent intellectual property rights, with a total of 12 national patents.

  • Visual LCD screen enables full control and monitoring from equipment setup; networked data collection allows real-time monitoring of each machine’s daily output and working hours, while also tracking inventory and processed steel quantities at any time.

    Operating Procedure

    1. Switch on the power supply of the control console.

    2. Switch on the power supply of the main machine.

    3. Turn on the power switch and check whether the sequence of the main machine cables is correct.

    4. On the screen, click to press the large wheel (the small wheel will automatically release), then insert the rebar. Click to release the large wheel (the small wheel will automatically press).

    5. On the screen, click the small wheel feed button to send the rebar under the large wheel. Then press the large wheel again, and click the large wheel feed button to move the rebar to the cutter position.

    6. Rotate the knob to adjust the return parameters, then click start.

    7. Test a single rebar for normal use: select any built-in shape, choose the single option, set to automatic operation, then click the start button to check if the machine produces stirrups correctly.

    8. After the single stirrup straightening test runs normally, rotate to set continuous operation to begin normal production.

    9. Enter the required rebar shape, length, and quantity on the screen, then click start to operate normally.
