One-stop Bending Solutions For Wires, Tubes And Pipes
Pipe bending machines are equipment that bends metal pipes (such as steel pipes and aluminum pipes) through mechanical force or hydraulic systems. They are mainly divided into CNC pipe bending machines, hydraulic pipe bending machines and manual pipe bending machines. In furniture manufacturing, CNC pipe bending machines have become the mainstream choice due to their high precision and high degree of automation.
Ⅰ. Application of pipe bending machines in furniture manufacturing
Modern metal furniture: pipe bending machines are widely used in metal frame furniture, such as chairs, tables, bookshelves, etc., which can achieve smooth curve design and enhance the beauty and comfort of products.
Customized furniture: Through CNC programming, pipe bending machines can quickly adjust parameters to meet personalized needs, such as special-shaped handrails, artistic brackets, etc.
Structural optimization: Compared with traditional welding processes, pipe bending technology can reduce connection points and improve the overall strength and stability of furniture.
Ⅱ. Benefit advantages of pipe bending machines
Improved production efficiency: Automated pipe bending machines can complete mass production in a short time, reduce manual operations, and improve accuracy.
Optimized material utilization: Precise bending process can reduce waste and lower raw material costs.
Environmental advantages: Compared with traditional welding, the pipe bending process reduces harmful gas emissions and is in line with the trend of green manufacturing.
III. Technical features
1.Comparison of driving modes
| type | Power Source | Applicable scenarios | Accuracy |
| Hydraulic type | Hydraulic system | Thick-walled pipe, large diameter pipe bending (Φ≥50mm) | ±0.5° |
| CNC type | Servo motor | Complex space curves, multi-angle continuous bending | ±0.1° |
| Manual type | Mechanical lever | On-site rapid processing of small diameter pipes (Φ≤38mm) | ±1° |
The CNC system integrates touch screen programming, supports 16 sets of process parameter storage and call, and has stronger adaptability.
2.Dynamic compensation technology
Equipped with a pressure sensor to provide real-time feedback on the deformation resistance of the pipe, automatically adjust the hydraulic output, and avoid bending cracks/wrinkling. According to the rebound characteristics of the aluminum tube, a 2°~5° bending compensation value is preset to ensure the accuracy of the finished product angle.
3.Precision and process control
4.Core precision indicators
Bending angle error: CNC models can reach ±0.1° (hydraulic models ±0.5°)
Cross-sectional ovality: high-precision models are controlled within ±3% to ensure the sealing of fluid pipelines.
Minimum bending radius: up to 1.5D (D is the pipe diameter), meeting the needs of compact space layout.
5.Material adaptability technology
Cold bending process: 6061-T6 aluminum tubes and stainless steel tubes are formed at room temperature, and the surface is not oxidized (wall thickness ≤4mm).
Hot bending process: Thick-walled tubes (＞4mm) are locally heated to 300℃ to reduce the risk of cracking.
Mold lubrication system: Silicone oil is automatically sprayed to reduce the stretching and wrinkling of thin-walled tubes.
Ⅴ. Efficiency and intelligent upgrades
1.Compound processing capabilities
The three-station turntable simultaneously completes tube cutting, shrinking, and bending, reducing clamping time by 30%.
The hydraulic system also serves as a jack to expand the functional scenarios of the equipment.
2.Intelligent process integration
AI visual detection of the curvature of the bend, real-time comparison of 3D models and correction of the path.
High-frequency heating technology (such as bending wood press) shortens the gluing and curing time to 1/5 of the traditional process.
Ⅵ. Cost optimization features
