1. Introduction

Metal forming operations can often lead to bending and deformation. To overcome this, a Straight Machine is employed by manufacturers to bring the product back to the original size and dimension.

The equipment increases the quality of the product and ensures that the downstream operations can be performed seamlessly.

Nanjing Bangwin Machine offers dependable straightening solutions to the modern automated production lines.

2. What Is a Straightening Machine 

A Straight Machine is used to eliminate bends and curvature from metal tubes, pipes, bars, and profiles. The machine exerts controlled pressure with rollers or dies.

Consequently, the metal regains its uniform straight shape. Moreover, straightening increases the accuracy of cutting, welding, and forming operations.

3. Working Principle Of Straightening Machine 

Straightening operation follows a stable workflow:

  • Feed raw materials into the machine
  • Pass the materials between the rollers
  • Applying progressive correction force
  • Adjust the roller pressure accurately
  • Remove the residual stress slowly
  • Discharge the straightened materials

The control method of the system is mechanical or servo. Every passage is of stable straightness.
