Operate the Fixed Cut-off and Straightening Machine Safely for Worry-free Production

Pre - operation Preparation: The Key

• Equipment Inspection: This is the foundation for ensuring the normal operation of the equipment. Check mechanical components such as cutting blades, transmission systems, and straightening rolls for wear or looseness. Examine whether the control panel, sensors, and circuits of the electrical system are in good condition. Also, make sure the lubrication system can provide sufficient lubrication for moving parts. For example, in a steel processing enterprise, due to failure to detect the looseness of the straightening rolls before operation, the straightening accuracy of steel decreased during production, and the equipment was damaged, affecting the production schedule.
• Safety Protection Preparation: Operators must wear protective gloves, goggles, safety shoes, and other equipment. At the same time, set up safety warning signs in the operation area, clear the surrounding debris, and ensure there are no flammable or explosive substances.
• Parameter Setting: According to the specifications of the materials and production requirements, accurately set the cutting length and quantity on the control panel, and reasonably adjust the cutting speed and tension. For instance, when processing thicker steel plates, a slower cutting speed is required.

Standard Operation Process: The Core

• Material Loading and Alignment: Install the coils on the feeding rack and adjust the position of the material through the guiding device so that it aligns with the center line before entering the straightening rolls and cutting area to prevent deviation.
• Equipment Start - up and Operation: After setting the parameters, run the equipment without load first to check the operating status of each component. During the automatic cutting process, observe whether the cut is smooth and burr - free, and the control system monitors the cutting length in real - time.
• Transportation and Stacking: The cut materials are transported to the stacking area through the conveying device. Ensure they are stable during transportation and stacked neatly to avoid collisions or warping.

Be Aware of Common Problems and Their Solutions

• Cutting Length Error: If there is a large cutting length error, it may be due to problems with the sensors or control system. You need to check and recalibrate the sensors and adjust the parameters of the control system.
• Excessive Burrs on the Cut: Usually, this is caused by the wear of the cutting blade. It is necessary to grind or replace the blade in a timely manner.
• Scratches on the Wire Surface: This may be due to the quality of the wire itself or the presence of burrs and sharp edges in parts such as the wire inlet nozzle and the pressure trunking of the pressure wheel of the straightening machine. Targeted inspection and treatment.

Post - operation Maintenance is Indispensable

• Equipment Shutdown: After completing the task, gradually reduce the operating speed of the equipment, stop the feeding and cutting devices, and turn off the power.
• Cleaning and Maintenance: Clean the iron filings and debris on the surface of the equipment, especially around the cutting blades and transmission components. Regularly check the wear of the cutting blades and replace them if necessary.
