Automatic Tube Bending Machine

Automatic Tube Bending Machine: Multi-Axis CNC Solutions for High-Precision Tube Fabrication

Fully automated feeding, spatial rotation, and multi-stack mandrel bending engineered for mass production with tight dimensional tolerances.

An Automatic Tube Bending Machine performs multi-axis material feeding, spatial rotation, and automated bending sequence execution without manual operator handling between bends.

Key Features of Automatic Tube Bending Machine

Multi-Axis Servo Control

Simultaneous multi-axis movement delivers continuous three-dimensional bending sequence execution and repeatable part geometry.

Automatic Material Feeding

High-torque servo drives advance material precisely along the longitudinal axis with feed repeatability within 0.1 millimeter.

Precision Spatial Rotation

Servo-driven clamp rotation controls multi-plane angular positioning with rotational indexing precision within 0.05 degrees.

Direct 3D File Import

Control software accepts standard STEP and IGES model files directly, eliminating manual programming of bending coordinates.

Automatic Tube Bending Machine With Loading And Unloading

Why Choose Us

Stress-Relieved Machine Bed

Heavy welded steel base plates undergo full heat treatment stress relief to eliminate structural distortion during heavy bending cycles.

Multi-Stack Tooling Capacity

Machine head accepts up to three tool stacks simultaneously, allowing different bend radii on a single tube profile without tool changes.

Direct Servo Drive Actuation

AC servomotors handle positioning directly, avoiding thermal expansion variation and operational drift associated with hydraulic power units.

Pre-Shipment Factory Testing

Machines complete a continuous 72-hour operating run using verified customer tube specifications prior to shipment dispatch.

FAQ

Q: What is the minimum center line radius capability?

A: Standard tool geometry supports a center line radius down to 1.5 times tube outer diameter. Utilizing an internal mandrel and wiper die configuration enables a radius of 1.0 times tube outer diameter while maintaining circular cross-section profiles.

Q: How does the control system process CAD drawings?

A: The control interface reads standard 3D CAD file formats directly and automatically extracts bend angles, spatial rotations, and leg lengths into machine execution code.

Q: How is material springback accounted for during operation?

A: The control software stores springback compensation curves. Angle corrections update automatically based on initial sample bend measurements and material tensile properties.

Q: What electrical power connection is required?

A: Standard systems operate on three-phase industrial voltage configurations tailored to site requirements.

Q: What is the typical timeframe for tooling changes?

A: Quick-release clamping mechanisms enable complete die set replacement within 15 to 20 minutes for standard tube diameter sizes.
