What is Tube Bending? Types and Working

Tube Bending

Tube bending is a complex manufacturing process used to shape metal tubes into different shapes and sizes. This type of fabrication process helps manufacturers produce parts for various industries, including automotive, furniture, and construction. It can also be used to create sculptures or other aesthetic pieces. Let’s take a look at how tube bending works and the different types of tube bending available.

How Does Tube Bending Work?

Tube bending uses pressure to shape metal tubes into specific shapes, such as U-shapes, V-shapes, and circles. The tube is placed into a die which holds it in place while pressure is applied to the outside of the tube by a hydraulic ram. The pressure forces the metal through the die opening and creates curves or angles in the tube without having to cut and weld it together. By using this method, manufacturers can save time and money while still achieving the desired shape.

Types of Tube Bending

There are several types of tube bending processes that can be used to achieve the desired shape or size including mandrel bending, rotary draw bending, compression bending, and roll benders. Each type has its own advantages depending on what type of product you are trying to manufacture. Mandrel bending uses an internal support tool called a mandrel that helps maintain the diameter throughout the bending process so there is no distortion or flattening during the bending process. Rotary draw bends use two dies that rotate around each other to form a precision bend with minimal distortion or flattening in small-diameter tubing. Compression bends use two dies that move past each other creating gentle curves with minimal distortion or flattening in small-diameter tubing. Finally, roll benders are best for creating large radius bends in thin wall tubing with minimal force required for larger radius bends.

Conclusion:

Tube bending is an important manufacturing process used to shape metal tubes into various shapes and sizes for many industries as well as aesthetic purposes. This process utilizes hydraulic pressure to force metal through a die opening without having to cut it apart first, which makes production faster and more cost-effective than traditional welding methods would allow for. There are several types of tube bending processes available, such as mandrel bends, rotary draw bends, compression bends, and roll benders, each of which provides unique benefits depending on what type of product you are trying to manufacture. With these options available, manufacturers have more flexibility when designing products using metal tubing, thus allowing them greater freedom when creating custom products that meet their needs perfectly!
