The structural design of fixed cut - off and straightening machines is elaborate and ingenious. Firstly, the straightening system usually adopts a multi - roll design, such as an eleven - roll or fifteen - roll structure. This multi - roll configuration can straighten steel wires more comprehensively and meticulously. It effectively improves the straightening accuracy and quality, making the steel wires straight and meeting various strict requirements.
In some designs, optimizations are made for different specifications of plates. For example, the small - roll system is specifically designed for straightening thin - gauge plates. The design of its roll diameter and the distance between roll centers can generate a large bending curvature, ensuring an ideal straightening effect for thin plates. On the other hand, the large - roll system focuses on strength to meet the straightening needs of thick steel plates.
In addition, some components in the equipment have special functions. For instance, in some straightening machines, the lower part of the small - roll system is equipped with a wedge - shaped lifting mechanism. When straightening thin - gauge plates, both the small - roll system and the large - roll system participate in the straightening process. When dealing with thick - gauge plates, the lower roll system of the small - roll system can be lowered through the wedge - shaped lifting mechanism, and only the large - roll system is involved in the straightening, achieving flexible switching and improving the equipment's applicability.

To improve the quality of plates, the roll diameters of some straightening machines are also carefully designed. This not only expands the straightening thickness range of the straightening process mainly based on the small - roll system but also extends the service life of the small - roll system.
The vertical position adjustment mechanism of the intermediate transition roll is also a highlight. Through structures such as hydraulic devices, the position of the intermediate transition roll can be adjusted individually, avoiding damage and defects caused by the plate colliding with the roll system during production.
In terms of the support structure, an optimized combination design is adopted, which increases the overall structural stiffness, reduces bounce, improves the reduction accuracy, and further enhances the product quality.
Meanwhile, the design of the quick - roll - changing device makes roll changing convenient and fast, saving time and labor costs.
To give full play to the advantages of fixed cut - off and straightening machines, here are some simple and practical operation suggestions:
- Equipment Inspection: Before starting the equipment, carefully check the condition of all mechanical components, including straightening rolls, the transmission system, hydraulic devices, etc., to ensure there is no wear, looseness, or malfunction. At the same time, check the electrical system to ensure that the control panel, sensors, wires, etc., are operating normally. Also, pay attention to the lubrication system to ensure sufficient lubrication.
- Straightening Parameter Setting: According to the specifications of the steel wires or plates to be processed and the quality requirements, precisely set parameters such as the spacing and angle of the straightening rolls to achieve the best straightening effect. For plates of different thicknesses, reasonably adjust the working states of the small - roll system and the large - roll system.
- Feeding and Alignment: Ensure that the feeding process of steel wires or plates is smooth and stable, avoiding jams or twists. Use guiding devices to accurately align the steel wires or plates before they enter the straightening area to ensure uniform straightening.
- Operation Monitoring: When the equipment is running, closely observe the straightening process. Pay attention to any abnormal vibrations, noises, or deviations. If problems are found, stop the machine in time for inspection and parameter adjustment.
- Regular Maintenance: Regularly clean the debris on the equipment surface and the 附着物 on the straightening rolls. Check the wear of the straightening rolls and replace severely worn parts in a timely manner. At the same time, tighten the connection parts of each component to ensure the stability and reliability of the equipment.
In conclusion, fixed cut - off and straightening machines demonstrate excellent performance in metal processing due to their reasonable structural designs. As long as you follow the correct operation and maintenance methods, you can fully utilize their advantages and provide strong support for producing high - quality products!
