Maintenance and Service Methods of Fixed-Cut Straightening Machine

In the field of metal processing, the fixed - cutting and straightening machine is a crucial piece of equipment. Its stable operation is directly related to the smooth progress of production and product quality. To ensure that the fixed - cutting and straightening machine always remains in good working condition and to extend its service life, proper maintenance and upkeep methods are essential. Today, we will introduce in detail the maintenance and upkeep techniques for the fixed - cutting and straightening machine.

Daily Maintenance
Cleaning Work
Equipment Surface Cleaning: After each day's work, use a clean rag or brush to remove dust, metal shavings, and oil stains from the surface of the fixed - cutting and straightening machine. In particular, areas such as the feed inlet, discharge outlet, straightening wheels, and feeding wheels are prone to debris accumulation. If not cleaned in a timely manner, it may affect the smooth conveyance of wires and the straightening effect.
Internal Cleaning: Regularly open the protective cover of the equipment to clean the internal dust and debris. During the cleaning process, be careful not to use overly sharp tools to avoid scratching the internal components of the equipment. For some hard - to - clean corners, compressed air can be used for blowing, but pay attention to controlling the air pressure to prevent damage to sensitive components.

Component Inspection
Mechanical Component Inspection: Check all mechanical components of the equipment daily, such as whether screws and nuts are loose. Pay special attention to the fixation of key components such as straightening wheels, feeding wheels, and cutting tools. If loose screws are found, tighten them in a timely manner to prevent component displacement during operation, which may affect processing accuracy and even cause safety accidents.
Transmission Component Inspection: Check whether the tension of the transmission chain and belt is appropriate. An overly loose chain may cause tooth skipping, affecting the transmission efficiency; an overly loose belt will cause slipping. If the chain or belt is found to be too loose or too tight, adjust it according to the requirements of the equipment manual. At the same time, check the wear of the chain and belt, and replace them in a timely manner if there is obvious wear.

Regular Maintenance
Lubrication Maintenance
Determine Lubrication Points: According to the instruction manual of the fixed - cutting and straightening machine, accurately identify all the parts that need lubrication, such as bearings, gears, and lead screws. These parts generate friction during the operation of the equipment, and good lubrication can reduce wear and extend the life of components.
Select Appropriate Lubricants: Select appropriate lubricants according to different lubrication parts and working conditions. Generally, for high - speed rotating bearings, high - speed grease should be used; for gear transmission parts, gear oil can be selected. Pay attention to the quality of the lubricant and avoid using inferior lubricants to prevent damage to the equipment.
Regularly Add Lubricants: Add lubricants to each lubrication point regularly according to the specified time interval. During the addition process, ensure that the lubricant is evenly applied to the surface of the components, and avoid over - adding to prevent lubricant leakage, which may contaminate the working environment and products.

Accuracy Calibration
Straightening Accuracy Calibration: Regularly check whether the straightness of the straightened wire meets the requirements. Sampling inspection can be carried out by placing the straightened wire on a platform and measuring the straightness deviation with a ruler or feeler gauge. If the straightness deviation exceeds the allowable range, the position and pressure of the straightening wheels need to be adjusted. The specific adjustment method can refer to the equipment manual. Usually, the distance and angle of the straightening wheels can be changed by adjusting the nuts of the straightening wheels to achieve the best straightening effect.
Cutting Length Calibration: Use standard measuring tools, such as calipers, to regularly measure the length of the wire cut by the fixed - cutting and straightening machine. If there is a deviation in the cutting length, the length setting device needs to be calibrated. Modern fixed - cutting and straightening machines mostly adopt a digital control system, and the length can be calibrated through the corresponding function keys on the operation panel. After entering the accurate calibration value, the equipment will automatically adjust the cutting length to ensure processing accuracy.

Electrical System Inspection
Circuit Inspection: Regularly check the electrical circuits of the equipment to see if there are any signs of damage, aging, or short - circuits. For exposed circuits, focus on checking whether the insulation layer is intact. If there is damage, replace it or carry out insulation treatment in a timely manner. At the same time, check whether each wiring terminal is loose to ensure a firm connection and avoid electrical failures caused by poor contact.
Electrical Component Inspection: Check the electrical components of the fixed - cutting and straightening machine, such as contactors, relays, and switches. Check whether the contacts of the components are ablated or oxidized, and clean or replace them in a timely manner if necessary. In addition, check whether the working status of the electrical components is normal, which can be judged by observing indicator lights and measuring voltage.

Handling Special Situations
Fault Handling
Troubleshooting of Common Faults: When a fault occurs in the fixed - cutting and straightening machine, first calmly analyze the fault phenomenon and troubleshoot according to experience and the working principle of the equipment. For example, if the straightened wire has an excessive degree of curvature, it may be due to wear of the straightening wheels, uneven pressure, or problems with the wire material itself; if the cutting length is inaccurate, it may be due to a fault in the length setting device, sensor failure, or instability of the feeding system.
Professional Repair: For some more complex faults, such as failures in the electrical control system or serious damage to mechanical components, it is not recommended that non - professional personnel disassemble and repair them on their own. Contact the after - sales service team of the equipment manufacturer or professional maintenance personnel in a timely manner. They have professional knowledge and tools, can accurately diagnose the cause of the fault and repair it, ensuring that the equipment returns to normal operation as soon as possible.

Maintenance during Long - term Shutdown
Comprehensive Cleaning: If the fixed - cutting and straightening machine needs to be shut down for a long time, carry out a comprehensive cleaning to remove all dust, oil stains, and debris inside and outside the equipment, preventing these substances from corroding and damaging the equipment during the long - term shutdown.
Protective Treatment: Apply anti - rust oil to the key components of the equipment, such as straightening wheels, feeding wheels, and cutting tools, to prevent rusting. At the same time, cover the equipment with a protective cover or dust - proof cloth to prevent dust and moisture from entering the equipment.
Regular Power - on: During the shutdown period of the equipment, it is recommended to power on the equipment and run it for a period of time (such as once a month). Let all components of the equipment operate for a while. This can prevent electronic components from being damaged by moisture and maintain the flexibility of mechanical components.

In conclusion, the maintenance and upkeep of the fixed - cutting and straightening machine is a meticulous and important task. Only by following the correct methods for daily maintenance, regular maintenance, and timely handling of special situations can the equipment always be in good operating condition and provide reliable guarantee for production. It is hoped that through the above introduction, it can help everyone better maintain and upkeep the fixed - cutting and straightening machine, improving production efficiency and product quality.
