Flanging process
The operation after disc-shaped is to shape the edges, which will weld the disc-shaped end to the tank body to support internal pressure. During the folding operation, the edge of the plate is formed by the folding roller, which moves relative to the radius of the forming roller. Two rollers rotate and bend the material at the required radius. This operation may cause lamination of the board. The best quality machine should be powerful enough to perform flipping with the least number of passes, thereby minimizing the thinning of the dished ends.
Minimizing thinning is one of the biggest challenges faced by flanging operators, as there are very strict tolerances on the dished ends, especially when there is high pressure inside the tank. Reducing sheet thickness means that manufacturers have higher production profits because they do not need to use thicker sheets to ensure minimum thickness.
To reduce lamination, it is important to have a machine with the correct geometry, sufficient rotational power, and good control over the movement of the flanging roller. Modern machines should be equipped with pressure control devices to assist operators by preventing the squeezing of plates. With the help of efficient gap control CNC, such machines can even allow inexperienced operators to perform flipping with the minimum number of passes.
A good flanging machine should also have a control device that always allows the roller to make optimal contact with the sheet metal. This includes the ability to tilt the edges and shape the rollers. Electric and hydraulic devices are the difference between high-quality and low-quality flanging machines. The hydraulic unit must allow for proportional and synchronized movement; For example, it is important to quickly move the bracket that fixes the disc-shaped end to the rest of the shaft.
The dished end can be flange connected with or without a central hole. Based on this, the flanging machine can have different configurations: with or without a closed structure. A disc end flanging machine without a central hole has a closed structure that allows two clamping cylinders to block the disc. In order to ensure smooth movement of these flanging machines, regardless of the clamping force, they must be equipped with the latest generation of frictionless technology, including ball guides for small car movement and ball screw positioning for precise movement.
Once a dished end is formed, the manufacturer must match tolerances for perimeter and depth. The flanging machine can be equipped with a processing arm to chamfer the edges of the sheet and adjust the height of the dished end. The most advanced machines have a precise system to measure the circumference of the disc end, making it easier for operators to provide perfect products.
Disc and flanging machines are machines with many important technical aspects and should be appropriately evaluated. Choosing the right machine can determine the success of a business.
