The roll forming of roll forming equipment uses sequentially configured multi-pass forming rolls to continuously bend metal sheets such as coils and strips laterally to form profiles with specific cross-sections. The roll forming process is suitable for producing long workpieces of equal cross-section in large batches, especially for large-volume products with an annual output of millions of pieces. The roll forming process is beneficial and has considerable economic benefits. At the same time, it can also be combined with various processes to form a continuous production line.
The roll forming equipment adopts a motor, a frequency converter and a high-hardness pressure roller, and the inclined block mechanically adjusts the gap. Used for pole piece roll forming. It has the advantages of low energy consumption and high efficiency, and is safe, simple and easy to maintain. It consists of unloading, rolling parts, safety protection devices and related electrical components. The whole machine is driven by a motor; the main control parts include start and stop buttons, forward and reverse adjustment, speed adjustment and indicator lights.
working principle
The operation process of the roll forming equipment is the same as that of the double-drive roller press. To a certain extent, one is a fixed roller and the other is a movable roller. The two rollers have the same speed and are completely synchronized. They run relative to each other. The material is fed from the upper part. Enter, crushed by high pressure in the gap between two rollers.
The metal roll forming machine is driven by a motor. The main shaft is rotated through the transmission system, and the workpiece is clamped by a three-jaw chuck to achieve its main movements, including the rotation of the workpiece, longitudinal feed and radial feed movements. All controlled by the rolling head.
In a metal roll forming machine, the workpiece passes through the central hole of the rolling head, and there are three rollers on the circumference of the rolling head, including a rolling wheel and two support wheels. Before work, through the spiral mechanism, these three rollers will radially approach and clamp the workpiece to maintain the center position of the workpiece. At the same time, they will rotate in the same direction as the spiral direction of the workpiece. Then the rolling wheel will feed radially to reach the workpiece. Location.
When working, the workpiece rotates and the rollers roll relative to each other through friction. At the same time, under the action of axial force, the rolling head drives the tailstock carriage to perform longitudinal feed motion along the bed guide rail. During the movement, the annular shoulder on the rolling wheel comes into contact with the workpiece, compressing the blank, causing stress concentration, which causes plastic deformation and eventually forms threads.
Roll Design Features:
Customized according to needs: The rolls of roll forming machines are designed and built according to specific customer requirements, so they are usually non-standard equipment, tailor-made to meet different production needs.
Even force distribution: All parts of the roll should bear the force evenly, which can ensure even wear and prolong the service life of the roll. This needs to take into account the force situation and the pressure of each roll during design.
Material selection: Usually, rolls will use materials with good wear resistance, such as C12MoV. But when choosing a material, hardness and strength must be balanced to ensure that the roll has sufficient durability and strength.
Roll protection: The upper and lower rolls or cross wheels need to be effectively protected to avoid problems during use. Pay special attention to the protection of slide rails, as they are susceptible to uneven forces, which may lead to blurred tracks, deformation and other problems, and shorten their service life.
Rolling stability: In the rolling process of cold-formed steel machinery, the rolling stability must be considered. If the material deflects left and right in the raceway, some measures may need to be taken to ensure the stability of the rolling process to obtain a high-quality finished product.
In general, the design of the roll is very important for cold-formed steel machinery, and multiple factors need to be considered, including customer needs, force balance, material selection, roll protection and rolling stability, to ensure the efficiency and stability of the machine. operation and long life of the rolls.
Metal roll forming machines have the following features:
- Low noise: This machine has low noise and will not cause much interference to the surrounding environment.
- Low pollution: The closed design can reduce noise transmission and reduce environmental pollution.
- High efficiency: The production efficiency is high, which can save time and improve production efficiency.
- Highly flexible production: Flexible production can be carried out according to different materials and process requirements to meet different production needs.
- Small footprint: The machine has a compact structure, light weight and takes up less space.
- Easy operation and maintenance: The structure is simple, operation and maintenance are relatively easy, and maintenance costs are reduced.
