At the same time, we will analyze the current market trends and future development directions, and reveal the huge potential of automatic tube bending machines in the wave of intelligent manufacturing. Through this article, readers will fully understand the technical details of automatic tube bending machines and their irreplaceable role in the manufacturing industry.

Technical principle of automatic tube bending machine

Working principle

The core function of the automatic tube bending machine is to precisely bend tubes made of metal or other materials according to preset angles and shapes. Its working principle mainly relies on mechanical transmission system and numerical control system (CNC) to achieve automation and precise control.

During operation, the tube is fixed on the fixture of the machine, and the tube is bent into the desired shape through rotation, push-pull or press bending.

Key components and technological innovations

CNC control system:

  • Function: The CNC (Computer Numerical Control) control system is one of the core components of the automatic tube bending machine. It controls various parameters of the bending process, such as bending angle, bending radius and feeding speed of the tube through pre-programmed instructions.
  • Advantages: The CNC system can achieve high-precision repetitive bending operations, reduce human errors and improve production efficiency.

Servo motor:

  • Function: The servo motor is used to precisely control the rotation and movement of the tube. Through the feedback system, the servo motor can adjust the speed and position in real time to ensure the accuracy of each bending action.
  • Advantages: The servo motor provides higher precision and response speed, making the bending process more stable and reliable.

Different types of bending techniques

Rotary Draw Bending:

  • Principle: By rotating the die, the tube is bent along the shape of the die. Usually used in situations where high precision and small radius bending are required.
  • Application: Widely used in automotive, aerospace and furniture manufacturing.

Press Bending:

  • Principle: Apply pressure to the tube through the die to force it to bend into shape. Usually used for bending thick-walled pipes.
  • Application: Commonly used in heavy machinery manufacturing and shipbuilding industries.

How to choose an automatic tube bending machine?

Choosing the right automatic tube bending machine is essential to improving production efficiency and ensuring product quality. Here are some key factors and steps to help you choose the most suitable equipment:

Determine production needs

Bending radius and angle:

Determine the minimum bending radius and maximum bending angle required to ensure that the machine can meet your bending requirements.

Pipe specifications:

Confirm the material, diameter and wall thickness of the pipe, as these factors directly affect the choice of machine. Different materials of pipes (such as steel, stainless steel, aluminum, etc.) have different requirements for bending machines.

Production volume and efficiency:

Consider the daily, monthly or annual production volume to select the appropriate machine model to ensure that the production capacity of the equipment can meet the needs.

Evaluate technical parameters

CNC control system:

Choose a CNC control system with high precision and stability to ensure bending accuracy and repeatability.

Understand the performance of servo motors, including their accuracy, response speed and durability, to ensure that they can provide stable power output.

Fixtures and dies:

Confirm whether the fixtures and dies provided by the machine meet your production needs and are easy to replace and adjust to adapt to different pipes and bending shapes.

Consider the versatility of the machine

Multiple bending technologies:

Choose a machine that can perform multiple bending technologies (such as rotary stretch bending, push bending and press bending) to adapt to different production tasks and process requirements.

Automation level:

According to the automation requirements of the production line, choose equipment with automatic loading, automatic unloading and intelligent detection functions to improve production efficiency and operational safety.

Understand the brand and after-sales service

Brand reputation:

Choose a reputable and technologically advanced brand to ensure the quality and performance of the equipment.

After-sales service:

Understand the after-sales service provided by the manufacturer, including equipment installation and commissioning, operation training, maintenance and technical support, to ensure timely and professional service during the use of the equipment.

Field inspection and trial machine

Field inspection:

Go to the equipment manufacturer or other user site for a field inspection in person to understand the actual performance and operating conditions of the machine.

Trial machine operation:

It is required to conduct a trial machine operation to observe the operating effect of the equipment, detect the bending accuracy and production efficiency, and ensure that it meets your production needs.
