RTZ16-16B type cold rolled ribbed bar equipment, hot rolled ribbed steel bar straightening and cutting machine, suitable for cold rolled ribbed steel bar straightening and cutting line, hot rolled ribbed steel bars (three steel) straightening and cut, construction, concrete, mesh processing length straight wire of the ideal equipment.The RTZ16-16B Cold-Rolled Ribbed Steel Bar Equipment and Hot-Rolled Ribbed Steel Bar Straightening and Cutting Machine are applicable for on-line straightening and cutting of cold-rolled ribbed steel bars, as well as straightening and cutting of hot-rolled ribbed steel bars (Grade III steel). It serves as an ideal equipment for construction projects, concrete components, and processing of mesh sheets with fixed-length straight bars.
● Feature 1: Straightening System:
Adopts the multi-wheel group straightening machine structure developed by our factory over many years. It utilizes both horizontal and vertical sets of multi-wheel straightening. The straightening system includes position movement memory detection. When switching to steel bars of different diameters, the straightening wheels automatically adjust upward or downward to achieve quick straightening (patented technology), reducing straightening time. The entire process is fully automatic. The multi-wheel group synchronously pulls the steel bars, reducing pressure between the wheels and the bars as well as traction force, thereby lowering energy consumption and material loss.
● Feature 2: Cutting System:
Equipped with imported servo motors to ensure cutting accuracy and support high-speed frequent start-stop cutting, significantly enhancing reliability and durability.
● Control System:
Utilizes advanced PLC program control, a color touchscreen display, and button input to minimize touchscreen damage caused by harsh environments. Key components employ imported brand-name products. The system includes fault identification and alarm functions.
1. Thirty sets of preset lengths enable efficient cutting of 500 mm lengths with high precision, making it a high-efficiency, low-loss equipment.
2.When installed after a wire drawing machine, it can form an efficient equipment unit for continuous rolling and online straightening. The straightening machine automatically tracks the speed of the wire drawing machine.
3.Features an innovative intermittent flying shear cutting mechanism. The motor operates for only 0.15 seconds per cut, reducing mechanical and electrical wear, extending service life, and ensuring high cutting accuracy. This design overcomes the shortcomings of traditional straightening machines, such as continuous cutting and poor operational reliability.
4.Employs the bending stress elimination principle for straightening, ensuring no scratching of the wire material and minimal strength loss after straightening.
5.The control unit is designed separately from the main machine to improve the reliability of the electrical control system.
6. The discharge rack adopts a 360-degree rotating design to prevent jamming and avoid issues like frequent adjustments and uneven discharging.
Note: Additional functions such as automatic stop when no material is detected, secondary material receiving, and finished product conveyor belts can be added according to user requirements.
Our company now launches a new model of straightening machine, which achieves a straightening speed of over 200 m/min. It delivers excellent straightening results with no flipping or twisting. Interested parties are welcome to inquire with our company.
