Introduction

Tube bending is a critical process in various manufacturing and construction industries where metal or plastic tubes are utilized. Understanding how tube benders work is essential for selecting the appropriate equipment that meets specific application needs.

Basic Principles of Tube Bending

Bending a tube requires careful consideration of the material properties, the desired bend radius, and the tube diameter. The primary challenge is to bend the tube without causing wrinkles or kinks.

Types of Tube Benders

Manual Tube Benders

Manual benders are cost-effective and suitable for small-scale operations. They require physical force to bend the tube around a die.

Hydraulic Tube Benders

Hydraulic benders use hydraulic pressure to exert force on the tube. They provide greater precision and are used for thicker or stronger materials.

Electric CNC Tube Benders

Electric CNC benders offer computer-controlled precision, allowing for complex bending operations with minimal operator intervention.

Working Mechanism of Tube Benders

Tube benders work by clamping the tube and applying force to bend it around a predefined radius. The process involves key parts such as the clamp die, pressure die, and bend die. The force required depends on the material properties, with the bending moment (M) defined as M = F × d, where F is the force applied, and d is the distance from the bending axis.

For example, bending a standard steel tube with a diameter of 50mm at a radius of 100mm requires careful calculation to prevent deformation.
