Product details
1. The basic principle of pipe bending machine
The pipe bending machine applies external force (mechanical force, hydraulic or electric drive) to make the pipe plastically deform under the guidance of the mold, and finally forms the required bending angle and curvature. The core components include:
Mold system: including bending mold (fixing the shape of the pipe), clamping mold (fixing the position of the pipe) and pressing mold (preventing the deformation of the pipe).
Drive system: hydraulic, electric or servo motor provides power.
Control system: CNC system accurately controls the bending angle, speed and radius.
2. Common types of pipe bending machines
Manual pipe bending machine
Bending is completed by manual operation of levers or hand wheels, which is suitable for simple processing with small batches and low precision.
Advantages: low cost and simple operation; Disadvantages: low efficiency and poor precision.
Hydraulic pipe bending machine
Use hydraulic system to drive the mold to bend the pipe, which is suitable for medium and large pipe processing.
Advantages: strong power and can handle thick-walled pipes; Disadvantages: high noise and complex maintenance.
CNC pipe bending machine (CNC pipe bending machine)
Control the bending parameters through computer programming to achieve high-precision and complex shape automated processing.
Advantages: high precision and good repeatability; Disadvantages: high cost, professional programmers are required.
Fully automatic pipe bending machine
Integrated feeding, bending, cutting and other functions, suitable for mass production.
Advantages: extremely high efficiency; Disadvantages: large equipment volume and high initial investment.
3. Application fields of pipe bending machine
Automotive industry: exhaust pipes, fuel pipes, brake pipes, etc.
Aerospace: hydraulic pipelines, fuel pipelines.
Construction industry: steel structure pipelines, plumbing pipelines.
Furniture manufacturing: metal frames, decorative pipes.
Energy field: oil and natural gas pipelines.
4. Key parameters for selecting pipe bending machine
Pipe material: copper, aluminum, stainless steel, carbon steel, plastic, etc.
Pipe diameter (OD): common range (such as Φ6mm~Φ200mm).
Wall thickness: affects the tonnage of the required pipe bending machine.
Bending radius (R): usually 1 to 5 times the pipe diameter.
Bending angle: 0°~180° or greater.
Control system: manual, semi-automatic, fully automatic CNC.
5. Safe operation and maintenance
Operation precautions:
Check whether the mold matches the pipe size.
Ensure that there are no cracks or defects on the pipe surface.
Avoid overload operation.
Maintenance:
Lubricate moving parts regularly.
Check the hydraulic oil level and cleanliness.
Clean mold residue to prevent jamming.
6. Common problems and solutions
Pipe wrinkles or deformation: adjust the core rod position or add fillers (such as sand).
Inaccurate bending angle: Check mold wear or calibrate the control system.
Hydraulic system oil leakage: replace seals or repair the oil circuit.
7. Future development trends
Intelligence: AI algorithm optimizes processing paths and reduces material waste.
High precision: application of servo motors and laser measurement technology.
Energy saving and environmental protection: low energy consumption design and hydraulic system optimization.
