A bending spring, also known as a tube bending spring or pipe bending spring, is a cylindrical coil spring used in metalworking to prevent tubing or piping from collapsing or deforming during the bending process. Here’s how it works and its typical applications:
- Purpose:
- Preventing Collapse: When tubing or pipe is bent, especially with tight radii or sharp angles, there is a risk that the wall of the tube could collapse due to the stress applied during bending.
- Support and Reinforcement: A bending spring is inserted into the interior or exterior of the tube to provide internal support and reinforcement, ensuring that the tube maintains its shape and integrity during bending.
- Design and Construction:
- Coil Shape: Bending springs are typically cylindrical in shape, resembling a tightly wound coil or spiral.
- Material: They are commonly made from hardened steel or other durable materials that can withstand the forces and pressures exerted during tube bending.
- Usage:
- Application: Bending springs are used in various industries, including plumbing, HVAC (Heating, Ventilation, and Air Conditioning), automotive, and aerospace.
- Procedure: Before bending, the appropriate size of bending spring is selected based on the diameter and material of the tubing.
- Insertion: The bending spring is inserted into the tube, either externally around the outside diameter or internally inside the tube, depending on the specific bending requirements and equipment used.
- Benefits:
- Prevents Damage: By providing internal or external support, bending springs minimize the risk of kinks, wrinkles, or collapse of the tube walls during bending.
- Improves Accuracy: They help achieve smoother bends and maintain the intended shape and dimensions of the tubing, ensuring high-quality finished products.
- Considerations:
- Spring Selection: Choosing the correct size and type of bending spring is crucial to match the diameter and material of the tube being bent.
- Safety: Operators must follow safety protocols when using bending springs and other bending tools to avoid injury and ensure proper handling of equipment.
In summary, a bending spring is an essential tool in metalworking processes where tubing or piping needs to be bent without compromising its structural integrity. It provides crucial support and reinforcement to prevent collapse or deformation of the tube walls during bending operations.
