Manhart What is the working principle of the bending machine?

The working principle of the roll bending machine is mainly based on the geometric principle of three points determining a circle, and the material is continuously bent into shape through multiple rollers. The following is a detailed explanation of the working principle of the bending machine:
###1、 Basic working principle
Roll bending machines, especially three roll roll bending machines, are usually equipped with two transmission rollers (fixed) and one adjustment roller (adjustable). These two transmission rollers are responsible for stably conveying materials, while the adjustment roller can move forward or backward as needed to change the relative distance between it and the transmission roller, thereby achieving bending of the material.
During the bending process, the material is placed between the transmission roller and the adjustment roller. As the adjusting roller gradually presses down (or advances), the material bends under continuous pressure, ultimately forming the desired radius (or arc). This method of controlling the bending radius by adjusting the distance between rollers enables the bending machine to flexibly handle metal profiles of different shapes and sizes.
###2、 Technical features and advantages
1. High flexibility: The roll bending machine can adjust the distance and angle between the rollers according to the characteristics and bending requirements of the material, and achieve bending with different curvature radii to meet diverse production needs.
2. * * High precision * *: Advanced bending machines use modern means such as servo technology and PLC control systems to achieve high-precision bending operations, reducing errors and deformations.
3. * * Wide applicability * *: Roll bending machines are widely used in aluminum alloy doors and windows, automotive industry, aerospace, high-speed rail, wind power generation, ships, large buildings, bridges and other engineering fields, and can handle the bending of various metal profiles.
4. * * Easy to operate * *: Modern bending machines are usually equipped with touch screen operation interfaces and memory storage functions, making the operation more convenient and efficient.
###3、 Safety and Maintenance
When using a bending machine, the following safety and maintenance precautions should be taken into account:
1. Operators should receive professional training to ensure they understand the operating methods and safety regulations of the rolling machine.
2. * * Regularly inspect equipment * *: including checking the wear and looseness of components such as rollers, bearings, and transmission mechanisms, as well as the pressure and leakage of hydraulic systems.
3. * * Comply with operating procedures * *: During the operation process, it is necessary to strictly follow the procedures to avoid equipment damage or personnel injury caused by illegal operations.
4. * * Keep equipment clean * *: Regularly clean the surface and interior of the equipment to maintain a clean environment and reduce the impact of impurities on the equipment.
In summary, the working principle of the roll bending machine is to continuously bend materials through multiple rollers, which has the advantages of high flexibility, high precision, wide applicability, and easy operation. During use, it is necessary to pay attention to safety and maintenance measures to ensure the normal operation of the equipment and extend its service life.
