  • Semi-Automatic Pipe Bending Machine
    Semi Automatic Hydraulic Mandrel Pipe Bending Machine has an NC control unit to allow the operator to program the bend degree (C axis)-the standard memory can store up to 16 programs each with 16 sequential bends.This allows the operator to select from the memory to bend sequence they require and load the tube and start bending. The rotating and feeding (B&Y axis) are controlled manually. Other movements as die working,mandrel working are controlled by hydraulic. Pipe Bending Machine combines easy-to-use operation with high bending accuracy and cost effectiveness. It is the practical semi-automatic solution for small to medium productions.
  • Fully Automatic CNC Tube Bending Machine
    Full automatic china cnc tube bender for tube is full automatic type machine for bending three dimensional complicated workpiece., which can input YBC or XYZ into controlling system, and machine make the tube bend accordingly.

Tube Bending Machine Basic Introduction

A CNC tube bending machine is a fully automated machine operated by a computer. It uses heavy-duty mechanical parts operated by electrical motors, or sometimes by a hydraulic system. CNC tube benders can make complex bends to a very high degree of precision that hand formed parts simply can’t match.


Tube and pipe bending machines can be roughly divided into CNC pipe bending machines and hydraulic pipe bending machines. Mainly used for electric power construction, highway and railway construction, boilers, bridges, ships, furniture, decoration, and other aspects of pipeline laying and repair. The tube bending equipment has the advantages of multiple functions, reasonable structure, and simple operation.


Five Main Components of CNC Tube Bending Machine
Bend die: A round part that determines the radius of the bend.
Clamp die: A clamp that assists the bend die in gripping the tube as the bend die rotates.
Wiper die: A perishable part that prevents wrinkles on the inside of the bend.
Interlock mandrel: A perishable part that works alongside the wiper die to prevent wrinkles on the inside of the bend.
Pressure die: A large part that applies the appropriate pressure needed to the tube to bend it accurately.


Automatic Tube Bending Machine Technology

The tube and pipe bending machine perform the bending of the round pipe and tube, square pipe and tube, and the bending of the sheet. In the case of pure bending, when a tube with an outer diameter of D and a wall thickness of t is bent under the action of an external moment M, the outer tube wall of the neutral layer is subjected to the tensile stress σ1, and the tube wall becomes thin; The wall is subjected to tensile stress σ1, and the pipe wall becomes thicker. Moreover, the shape of the cross-section changes from a circle to an ellipse due to the combined forces F1 and F2. When the deformation is too large, cracks will occur on the outer tube wall and wrinkles on the inner tube wall.

The degree of deformation of the pipe depends on the relative bending radius R/D and the relative thickness t/D. The smaller the R/D and t/D values, the greater the degree of deformation. To ensure the quality of pipe forming, the degree of deformation must be controlled within the permitted range. The bending forming limit of pipes not only depends on the mechanical properties of the material and the bending method, but also considers the use requirements of pipe fittings. The forming limit of pipe fittings should include the following contents:
1. The maximum elongation deformation in the tensile deformation zone outside the neutral layer does not exceed the allowable value of the material's plasticity to cause rupture;
2. In the compression deformation zone inside the neutral layer, the part of the thin-walled structure under the action of tangential compressive stress will not exceed the instability and wrinkle;
3. If the pipe fitting has the requirement of ovality, control the distortion of its section;
4. If the pipe has a strength requirement to withstand internal pressure, control the forming limit of its wall thickness reduction.
