Before starting, conduct a no-load test run for 3 to 5 minutes to observe whether the equipment operates smoothly without any abnormal noise or vibration.
- Material compatibility verification
The diameter of the steel bars to be processed must be within the allowable range of the equipment, and there should be no severe rust or oil stains on the surface.
Check whether the ends of the reinforcing bars are flat to avoid material jamming or damage to the straightening wheels due to burrs.
Operation Process Norms
- Parameter setting and adjustment
Input parameters such as cutting length and number of pieces through the touch screen. After confirming that there are no errors, save them.
The angle of the straightening wheel should be fine-tuned according to the diameter of the reinforcing bars. It is recommended to refer to the equipment manual for the initial setting. During adjustment, gradually increase the pressure to avoid excessive tightening, which may damage the surface of the reinforcing bars.
- Feeding and cutting control
When feeding materials, keep the steel bars aligned with the center line of the guide cylinder and avoid tilting or bending.
When using flying shears for cutting, the operator must maintain a safe distance from the equipment and must not put their hands into the cutting area.
When processing long reinforcing bars, auxiliary brackets should be provided to prevent sagging and affecting straightness.
- Handling abnormal situations
If abnormal sounds, smoke, or odors occur during operation, immediately press the emergency stop button, cut off the power supply, and notify professionals for maintenance.
If material jamming occurs, stop the machine first to release the tension, and then clear the blockage. It is strictly forbidden to forcibly pull the steel bars.
Key Points for Maintenance and Care
- Daily maintenance
At the end of each day’s work, clean the metal debris on the surface of the equipment and in the cutting area, and use compressed air to blow away the impurities in the grooves of the straightening wheels.
Check the wear of the straightening wheel and cutting knife. Replace them in time if there are obvious notches or deformations on the cutting edge.
- Regular maintenance
- Weekly: Check the lubricating oil level of the reducer. If insufficient, add the specified type of gear oil. Clean the air filter and drain the condensate water in the air line.
- Monthly: Tighten the connecting bolts of components such as transmission chains and pulleys, and test the accuracy of encoders.
- Quarterly: Replace the hydraulic oil, clean the oil tank and filter element, and check for hydraulic pipeline leaks.
- Maintenance of key components
The straightening wheel should be disassembled and cleaned every 500 hours of operation. Worn bearings and polyurethane coating should be replaced.
The blade clearance of the cutting mechanism must be adjusted regularly to ensure a smooth cut.

How To Cooperate With Us
FAQ
Q: Can beginners get the hang of it quickly? Is parameter setting complicated?
A: So easy to operate! The 7-inch touch screen offers direct graphical settings with 100 preset parameters. Beginners can master it in just 30 minutes. For instance, if you want to change the cutting length, simply input the numbers and save them. When changing specifications, there’s no need for mechanical adjustment, making it both convenient and efficient.
Q: The machine suddenly won’t start and can only be started intermittently. What’s going on?
A: Don’t worry. It’s most likely that the counter automatically shuts down when it reaches the set quantity. Just reset the counter to zero on the display screen and then restart. If it still doesn’t work, press the emergency stop button to cut off the power and restart the machine. Our after-sales service can also provide remote guidance.
Q: Where is the problem if the steel bar cannot be cut or if there are burrs at the cut edge?
A: First, check these three points:
① Is the gap between the upper and lower knives too large? Adjust it to about 0.2 mm.
② Is there enough hydraulic oil? Lack of oil can lead to insufficient pressure.
③ Is the blade worn out? Our blades are made of highly wear-resistant material and are easy to replace. We have spare parts in stock.
Q: The cut steel bars are of different lengths. How can this be adjusted?
A: If the lengths are consistent but inaccurate, use the “error compensation” function on the display screen for calibration. If the lengths are inconsistent, check whether the straightening wheel is loose or if the encoder connection is firm. These minor issues can be resolved by following the instructions.
Q: Is daily maintenance troublesome? How often should vulnerable parts be replaced?
A: Not at all! Just clear debris daily, check lubricating oil weekly, and tighten bolts monthly. The straightening wheel should be replaced approximately every 500 hours, and the blade replacement depends on processing volume—usually every 3 to 6 months. The modular design allows replacement within half an hour, and maintenance costs are 30% lower than those of similar equipment.
Q: How long is the warranty period for the machine?
A: The entire machine is guaranteed for one year, and we offer lifetime remote maintenance and technical support. You don’t need to worry at all.
Q: If I want to process extra-long steel bars or special materials, can it be customized?
A: Of course! A 12-meter-long unloading frame and scratch-resistant polyurethane straightening wheels can both be customized. Simply state your requirements, and our engineers will provide solutions and perform debugging as needed.
