| Mandrel | Supports the internal diameter of tubes, preventing collapse during bending. | Usually made of durable materials suitable for different tube sizes. | For small-radius bends, ensure the mandrel effectively prevents the inner collapse of the material. | Maintains the integrity of the internal diameter of the tube, preventing collapse or wrinkles. | Regularly clean the mandrel to avoid dust and corrosion, ensuring smooth operation. |
Tip：When using multi-level bending machines, adjusting the cooperation between each component can significantly improve production efficiency and bending precision. Regularly checking the wear status of the components helps extend equipment lifespan and maintain production stability.
Rotary draw bending machines are widely used for bending tubes and pipes with high precision. This method involves securing the material onto a rotating die, which pulls it around a stationary bend die, creating smooth, consistent bends. These machines are ideal for producing complex shapes and are highly programmable, making them suitable for both small batch and high-volume production. In the automotive industry, rotary draw bending is often used to create roll cages, handrails, and frames, where precision is critical.
Roll bending machines are designed for bending metal plates or sheets into cylindrical or conical shapes. The process involves passing the material through a series of rollers that gradually shape it into the desired form. Roll bending is especially effective for creating large-radius bends with minimal deformation in the material’s cross-section. These machines are often used in industries such as shipbuilding and pressure vessel production, where bending large sheets or heavy plates is required for structural components. Roll bending also works well for continuous production, minimizing material waste.
Ram bending machines, also known as press benders, are among the simplest types of bending machines. The material is clamped between two dies, and a ram is used to apply force, creating the bend. This type of machine is more suited for simple, less intricate bending tasks where precision is not as crucial. Ram bending machines are commonly used for basic pipe bending, such as in smaller-scale operations or for making non-precision parts. While they are easy to operate and cost-effective, their lack of internal support may result in oval cross-sections in the bent material.
CNC (Computer Numerical Control) bending machines have revolutionized the bending process by automating it with high precision. These machines are capable of performing complex bending tasks based on pre-programmed instructions, which ensures consistency and reduces the chances of human error. CNC bending machines are ideal for industries where high precision is necessary, such as aerospace and automotive manufacturing, where components need to meet strict tolerances. They are capable of handling multiple operations in a single cycle, making them highly efficient and suitable for high-volume production.
Vector tube bending machines are designed to handle high-strength materials, providing precision and speed in bending metal tubes. These machines use a combination of rotary draw bending and automated feeding systems, which increases their speed and accuracy. They are perfect for applications where intricate bends are required, such as in aerospace and automotive industries. The vector bending process allows for quick adjustments and can be used for materials that are difficult to bend with traditional methods. These machines are well-suited for high-precision, high-volume operations where automation is key.
Induction bending machines use electromagnetic induction to heat the material at the bending point. Once the pipe or tube is heated, pressure is applied to create the bend, making this a highly efficient process. Induction bending is energy-efficient and eliminates the need for mandrels, which can be a costly and time-consuming addition in traditional bending methods. This makes it ideal for bending large pipes and tubes in industries such as oil and gas, construction, and heavy manufacturing. Induction bending allows for precise bends in a wide range of pipe sizes and angles, with the added benefit of reduced energy consumption.
Plate bending machines are designed to bend large metal plates into cylindrical or conical shapes. These machines are equipped with multiple rollers that apply pressure to the plate, shaping it as it passes through the machine. Plate bending machines are commonly used in industries that require heavy-duty bending, such as in the production of pressure vessels, tanks, and large-scale metal fabrication projects. They are suitable for materials like steel and aluminum, and they offer high precision for large-radius bends. These machines can handle large production runs and are built for tough industrial applications.
CNC technology revolutionizes bending by offering precise control over the bending process. This is particularly valuable when producing complex shapes that would be challenging with manual machines.
