Structure of Pipe Bending Machine

Pipe bending machines, commonly called tube benders, come in a lot of variety. Predominantly, they work electromechanically. Thanks to the latest technological developments, these machines are capable of accelerating production and improving repeatability. At the same time they are reducing the number of errors in production at every scale. The main parts of a tube bending machine are:

1. Bend Die
The bend die, also known as the bend form or the radius die, is the most important part of a rotary-draw bending machine. The tube clamps to the bend die and the drawing process produces the necessary bend. The selection of die is very important, as the tube's inside radius depends on it.

2. Clamp Die
The clamp die presses the tube onto the bend die. Its main purpose is to prevent the pipe from slipping.

3. Pressure Die
The pressure die makes sure the tube follows the bend die's contour.

4. Wiper Die
A wiper die places just after the bend die. The purpose is to avoid the formation of any humps on the inside radius.
During the forming process, the material turns plastic during bending. It may result in wrinkles with large deformations. Thus, adding a wiper die just after the bend die helps to smooth the surface.

5. Mandrel
In bending steel and aluminium tubes, a mandrel is necessary for more difficult jobs. Bending a small radius, thin tubes or harder materials can result in an unsatisfactory outcome. In those cases, a mandrel can be handy. The mandrel's objective is keeping the tube from collapsing.

Applications of Pipe Bending Machine

Automobile manufacturing

In automobile manufacturing, pipe bending machines are widely used to manufacture components such as exhaust pipes, cooling system ducts, vehicle frames, and seat structures. It enables precise bending, ensuring the quality and performance of automotive components.

Aerospace industry

In the aerospace industry, pipe bending machines are used to manufacture fuel pipes, cooling systems and structural components for aircraft and satellites. High-precision bending is critical to ensuring the safety and performance of aircraft and satellites.

Construction and home appliance manufacturing

In construction and home appliance manufacturing, pipe bending machine is used to manufacture various pipes and structural components, such as air conditioning ducts, refrigerator cooling pipes, building structures, etc. It can perform large-volume bending processing and improve production efficiency.

Pipe Bending Machine - Different Bending Methods

Press Bending
Press bending is one of the simplest types of pipe bending processes. In press bending, two dies that contain the shape of the bend are pressed against the pipe that requires bending. When these pressure die are pressed against the pipe, the shape of the bend is imprinted on the pipe.

Rotary Draw Bending
Rotary draw bending is one of the most widely used tube bending processes. It is used for making roll cages, furniture frames, handrails, and many other applications. The radius of the bend die is the same as the required radius of the bend.

Compression Bending
Compression bending is a bending method of the past and is rarely applied nowadays. In compression bending, the pipe is clamped at both ends, and pressure is applied at the point of the required bend, so the bend moves into space.
Compression bending is generally used in the construction sector for the bending of electrical conduits.

Roll Bending
In roll bending, a series of rollers push the pipe through a coil of the required bend angle. Generally, 3 to 4 rollers are found in the roll bending machine. Roll bending machines can be used to create coils of pipes and truss rod bends.

Mandrel Tube Bending
Mandrel bending is a very common bending technique. Mandrel bending is applied to hollow tubes and involves placing internal support in the tube to protect it from collapsing during the bending process. It is used for creating exhaust pipes for automobiles, aerospace equipment, and exercise equipment.

Wiper Die Bending
Just like mandrel tube bending, wipe die is another modification of the other bending processes like rotary draw bending. In this technique, a die called wiper die is placed beside the bending die to prevent the formation of wrinkles and exceeded flow of material of the tube.

Heat Induction Bending
The heat induction bending method is usually applied for the creation of pipelines in the petrochemical industry. This method is also used in the large radius components that you see in the construction industry, as well as in the power distribution sector.

Sand Packing and Hot Slab Forming
Sand packing and hot slab forming is a combination of multiple techniques. First, the pipe is filled with sand and closed at both ends. Then the pipe is heated in a furnace to a high temperature. After that, it is held on a slab with pins at both ends and bent around with force from a winch or crane.

Ring Roll Bending
Ring roll tube bending is applied to metal strips of minimal wall thinning instead of tubes and pipes. Metal strips are formed into curved bands with machines called ring roll bending machine. These curved bands can then be joined together through welding to form rings.

Ram Bending
In ram bending, the tube is placed on stationary dies called counter dies, which are placed at an angle relative to the bend angle required. A pressure die then applies a force to the tube and creates the required bend.

Safety Rules for Using Pipe Bending Machine

Wear Protective Equipment
One of the most important safety precautions when bending metal is to wear proper protective equipment. This includes safety goggles, gloves, earplugs, and a hard hat. Metal sheets can produce sparks, debris, and noise that can harm your eyes, skin, and ears. Make sure you wear the appropriate gear to protect yourself from these hazards.

Follow Machine Safety Guidelines
When using metal bending machines, it is crucial to follow the safety guidelines provided by the manufacturer. This includes understanding the machine's capabilities, limitations, and safety features. Ensure you read the user manual before using the machine, and never modify or remove any safety features. Always turn off the machine before making any adjustments or repairs.

Use Proper Lifting Techniques
Bending metal sheets often requires lifting and moving heavy objects. To prevent back injuries, it is important to use proper lifting techniques. This includes bending your knees and lifting with your legs, not your back. In addition, ensure you have a clear path to move the metal sheet and avoid twisting your body while lifting.

Maintain a Clean and Organized Work Area
A clean and organized work area can prevent accidents and injuries when bending metal. Make sure you keep your work area clean and free of clutter. It includes removing any scraps or debris from the floor and keeping your tools and equipment organized. A cluttered work area can lead to trips, slips, and falls, resulting in serious injuries.

Never Work Alone
Metal bending is a dangerous activity, and accidents can happen unexpectedly. To ensure your safety, it is essential to always work with others. Always have a colleague or co-worker nearby to assist or alert emergency services. Additionally, ensure you have a first aid kit and a phone nearby in an emergency.
