1. Overview of the 63NC Pipe Bending Machine
The 63NC pipe bending machine is a semi-automatic 2D hydraulic tube bending solution designed for efficient and precise forming of metal pipes across a wide range of industries. By combining hydraulic power with NC (Numerical Control) technology, the machine achieves a balance between performance, accuracy, and cost-effectiveness.
When used together with properly designed molds, the machine can perform multiple bending tasks and adapt to various pipe shapes and process requirements. Compared with fully CNC pipe bending equipment, the 63NC model is easier to operate, more economical, and highly practical, which has enabled it to dominate the domestic tube processing equipment market.
The machine is particularly suitable for mass production environments that require stable quality, high efficiency, and low operating costs. Typical applications include furniture manufacturing, fitness equipment, medical devices, automotive piping, and air-conditioning systems.
2. Structural Design and Mechanical Construction
Integrated Machine Body
The 63NC pipe bending machine adopts an integrated machine body design, ensuring excellent rigidity, structural stability, and vibration resistance during operation. This solid construction guarantees consistent bending accuracy even under long-term, high-load production conditions.
Machine Head and Sliding Components
The machine head is manufactured from ductile cast iron (QT500-7) using a single-piece casting process. This material provides high strength, excellent wear resistance, and long service life.
To further enhance durability, the moving slider is equipped with wear-resistant copper strips. This design prevents direct friction between the slider and the bending arm, significantly reducing mechanical wear and extending the overall lifespan of the machine head.
3. Control System and Operation Interface
NC Control System
The machine is equipped with a microcomputer-based NC control system, offering reliable and precise control over the bending process. Electrical components are sourced from well-known Taiwanese or world-renowned brands to ensure operational stability and long-term reliability.
Human–Machine Interface
An LCD screen with Chinese display is provided as standard, while other languages can be customized upon request. The push-button and touchscreen operation interface allows operators to quickly set parameters and manage programs with minimal training.
Foot Switch and Safety Features
A mobile foot pedal switch is included, integrating both start and emergency stop functions. This design improves operational flexibility while ensuring operator safety during production.
4. Bending Modes and Operational Flexibility
The 63NC pipe bending machine supports multiple operating modes to accommodate different production needs:
- Manual mode
- Semi-automatic mode
- Fully automatic mode
The machine can be configured for bending with or without a mandrel (core) depending on material type, wall thickness, and bending requirements. A workpiece counting function is also integrated to assist with production tracking and batch management.
5. Bending Accuracy and Quality Control
Hydraulic-controlled bending ensures stable and repeatable performance, with a standard bending accuracy of±0.5°. Through angle compensation and NC fine-tuning, bending accuracy can be reduced to±0.15°, meeting high-precision requirements.
The system includes an automatic error and fault detection function. Any abnormal conditions or machine faults are displayed directly on the screen, allowing operators to quickly identify and resolve issues.
A power-off memory function ensures that all data and parameters are retained in the event of power interruption, preventing data loss and production delays.
6. Mold System and Configuration
Mold Components
The complete mold system includes:
- Bending mold
