Bending is a process of bending metal. The metal can be sheet metal, tubes, square hollow, rod, and iron angle. This type of metal has its own thickness. In bending machine designing several considerations are taken into including the type of metal, type of roller bender, power-driven or manual, and the size of the bending machine.
Usually, the difference between these types of bending machines is only in the capacity of the bending machine that can bend sheet metal or tube. Today, the bending machine that is available in the market is sheet metal and tube bending machines. Many machine makers vary their products based on the capacity of the bending machine and power-driven or manual.
Moreover, most of the machine uses roll bending type. This type of machine has 3 rolls which are 1 roll fixed and the other 2 are adjustable. The sheet metal needs to be put in the roller and then rolled around it until the desired shape is acquired. The products that can be produced with this machine are coil, truncated cone, etc.
As we know that pipe bends are used in various household things therefore it is necessary to build an economical pipe-bending machine. It is also used in designing of various machine components, without this bending device a machine can’t work properly.
As far as industrial application is concerned it is used for piping purposes. The reason to design a bending machine is that there is no proper bending machine to bend a solid or hollow pipe on a small scale. The bending machines found in the market come in a variety of types. There are bending machines such as press brake bending machines, roll bending machines and folding machines.
Tube bending machine manufacturers
The Forming Roller method of tube bending is recommended for all large bends where the centerline radius is at least 4 times the outside diameter of the tube. It can also be successfully employed for bending pipe or heavy wall tubing to smaller radii and is the most practical method of bending very small-diameter tubing.
The Forming Roller and Radius Collar must be grooved to exactly fit the tube and the tube must not be allowed to slip during the bending operation as even a slight amount of slippage will cause distortion.
This operation is somewhat involved by the fact that most materials “spring back” after they have been formed. To compensate for this, it is often necessary to use a Radius Collar having a smaller diameter than that of the circle required. Actual size can best be determined by experiment, as the “spring back” varies in different materials. The material should be precut to the exact length before forming.
The same general bending rules which cover the forming of the channel with “flanges out” also apply when it is formed with “flanges in.” Since it is necessary to compress the flanges as they are bent inward, the operation shown below requires considerably more bending pressure than when forming with the “flanges out” and it is recommended that the largest possible radius be used to allow for compression of the material. if a sharp 90° bend is desired, it can be obtained by cutting a notch out of the channel flanges before forming around a special Zero.
Radius Block as illustrated. It is sometimes possible to make a circle in the channel by using a segment of a Radius Collar similar. By following the procedure outlined, the circle can be formed in three operations. To form a channel with the flanges facing upward it is necessary to first fill it with Cerro bend or some other commercial filler as it is not possible to support the flanges in this position with a radius Collar.
Square Pipe Bending with EMS TB Pipe Bending Machine
Square pipe bending is a process of shaping and curving square or rectangular pipes and tubes into desired angles or shapes. This method is commonly used in various industries, including construction, manufacturing, and plumbing, for creating functional and aesthetically pleasing structures.
Methods of Square Pipe Bending
There are several methods of square pipe bending, each with its own advantages and limitations. Some common methods include:
- Mandrel bending: Mandrel bending utilizes a mandrel, a solid rod or bar, inserted into the pipe to prevent collapse or distortion during bending. This method is particularly suitable for bending thin-walled pipes or achieving tight bends.
- Rotary bending: In rotary bending, the pipe is rotated around a stationary bend die, gradually forming the desired curvature. Rotary bending is well-suited for bending pipes with large diameters or long bends.
- Roller bending: Roller bending employs multiple rollers to apply pressure and shape the pipe as it passes through the machine. Roller bending is versatile and can handle various pipe sizes and bend radii.
- Hydraulic bending: Hydraulic bending utilizes hydraulic pressure to apply force to the rollers or bending beam, providing powerful and precise bending capabilities. Hydraulic bending is commonly used for bending thick-walled pipes or high-strength materials.
Factors Affecting Square Pipe Bending
Several factors influence the bending process and the selection of an appropriate bending machine for square pipes. These factors include:
- Pipe Material: Different materials have varying bending characteristics, such as ductility, strength, and springback. These properties affect the bend radius, bend angle, and overall accuracy achievable during bending.
- Pipe Thickness: Thicker pipes are more difficult to bend than thinner pipes. This is because thicker pipes require more force to deform and may experience more springback.
- Desired Bend Radius: The bend radius is the tightest bend that can be made in the pipe. Smaller bend radii require more force and specialized machines.
- Desired Bend Angle: The bend angle is the angle at which the pipe is bent. Larger bend angles require more force and specialized machines.
- Production Requirements: The production requirements, including the volume of pipes to be bent and the desired production rate, influence the choice of the bending machine’s capacity and speed.
Selection of Square Pipe Bending Machines
Selecting the appropriate square pipe bending machine depends on several considerations, including:
- Pipe Size and Material Compatibility: The machine should be capable of handling the pipe size and material being bent.
- Bend Radius and Angle Capabilities: The machine should be able to achieve the desired bend radius and angle.
- Production Volume and Speed Requirements: The machine should have sufficient capacity and speed to meet the production demands.

- Securely Position the Machine: Ensure the machine is securely placed and leveled on a stable surface to prevent movement during operation.
- Properly Align the Bend Die: Make sure the bend die is properly aligned with the pipe to ensure a smooth, consistent bend.
- Monitor the Bending Process: Closely monitor the bending process to detect any potential issues or irregularities.
- Follow Manufacturer Instructions: Strictly follow the manufacturer’s instructions and safety guidelines for the specific pipe bending machine in use.
Conclusion
Square pipe bending is a versatile and essential technique for shaping and curving square or rectangular pipes into desired angles or shapes. By selecting the right machine, adhering to safety protocols, and following proper operating procedures, these machines contribute to efficient, safe, and productive manufacturing processes in various industries.
Forming zero radius bends around the square, rectangular, or other multisided blocks employs the same principle used in scroll bending. Forming Nose “leads” material between corners of the block. Any number of zero radius bends can be obtained in one operation by this method in all types of solid materials.
Both centered and off-center square eyes can also be formed by following the same procedure outlined. This method of bending is limited by the size of the square block and the ductility of the
material. In general, when squares larger than 1” are needed, they should be formed in progressive operations using the zero radius blocks.
Working on a Steel Pipe Bending Machine
Pipe bending as a process starts with loading a tube into a pipe bender and clamping it into place between two dies, the clamping block, and the forming die. The tube is also loosely held by two other dies, the wiper die and the pressure die. A pipe bending machine is a simple bending machine that is operated by an a.c or d.c motor. The motor is attached to the frame of the machine and also consists of a circular die on which the vice to hold the rod is welded.
Hydraulic machines are machinery and tools that use liquid fluid power to do simple work. Heavy equipment is a common example. In this type of machine, hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders and which become pressurized according to the resistance present. The fluid is controlled directly or
automatically by control valves and distributed through hoses and tubes.
The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power. Hydraulic machinery is operated by the use of hydraulics, where a liquid is a powering medium.
Parts of a Hydraulic Pipe Bending Machine
The main parts of a hydraulic pipe bending machine are:
- Frame: The frame is the main structural component of the machine and provides support for all other components. It is typically made of heavy-duty steel and is designed to withstand the forces involved in bending pipes.
- Hydraulic Cylinder: The hydraulic cylinder is the heart of the machine and is responsible for applying the force necessary to bend the pipe. It contains a piston that is driven by hydraulic fluid, which is supplied by a hydraulic pump.
- Bend Die: The bend die is the tool that shapes the pipe into the desired bend radius. It is typically made of hardened steel and is interchangeable to accommodate different pipe sizes and bend radii.
- Hydraulic Pump: The hydraulic pump is responsible for supplying the hydraulic fluid to the hydraulic cylinder. It is typically a gear pump or a vane pump and is driven by an electric motor.
- Control Panel: The control panel allows the operator to control the bending process. It typically includes a pressure gauge, a speed control, and a timer.
- Foot Pedal: The foot pedal is used to activate the hydraulic cylinder and start the bending process. It is typically located on the floor near the machine.
- Pipe Clamp: The pipe clamp is used to secure the pipe to the machine during bending. It is typically adjustable to accommodate different pipe sizes.
- Hydraulic Hose: The hydraulic hose is used to convey hydraulic fluid from the hydraulic pump to the hydraulic cylinder. It is typically made of reinforced rubber or plastic.
- Hydraulic Reservoir: The hydraulic reservoir is used to store hydraulic fluid. It is typically located on the machine or in a separate tank.
- Filter: The filter is used to remove impurities from the hydraulic fluid. It is typically located in the hydraulic reservoir or in the hydraulic hose.
In addition to these main components, hydraulic pipe bending machines may also include other features, such as:
- Automatic bend angle and radius control: This feature allows the operator to program the desired bend angle and radius, and the machine will automatically bend the pipe to the specified dimensions.
- Data logging and monitoring: This feature allows the operator to track the bending parameters for each bend, which can be useful for quality control and process optimization.
- Remote control: This feature allows the operator to control the machine from a distance, which can be useful for bending pipes in hazardous or inaccessible locations.
Hydraulic pipe bending machines are versatile and powerful tools that can be used to bend a wide variety of pipes, including steel, aluminum, and stainless steel. They are commonly used in construction, manufacturing, and plumbing.
The Cylinder Barrel: The main function of the cylinder body is to hold cylinder pressure. The cylinder barrel is mostly made from a seamless tube. The cylinder barrel is ground and/or honed internally with a typical surface finish of 4 to 16 micro inches. Normally hoop stresses are calculated to optimize the barrel size.
Cylinder base: The main function of the cap is to enclose the pressure chamber at one end. The cap is connected to the body by means of welding, threading, bolts, and tie rod. Cap also performs as a cylinder mounting component. Cap size is determined based on the bending stress.
Cylinder head: The main function of the head is to enclose the pressure chamber from another end. The Head contains an integrated rod sealing arrangement or the option to accept a seal gland. The head is connected to the body by means of threading, bolts, tie rod. A static seal / o-ring is used between the head and barrel.
Piston: The main function of the piston is to separate the pressure zone in the side barrel. The piston is machined with grooves to fit elastomeric or metal seals and bearing elements. These seals can be single-acting or double acting. This difference in pressure between the two sides of the piston causes the cylinder to extend and retract. The piston is attached to the piston rod by means of threads, bolts, and nuts to transfer the linear motion.
Piston rod: The piston rod is typically a hard chrome-plated piece of cold-rolled steel that attaches to the piston and extends from the cylinder through the rod-end head. In double rod-end cylinders, the actuator has a rod extending from both sides of the piston and out both ends of the
barrel. The piston rod connects the hydraulic actuator to the machine component doing the work. This connection can be in the form of a machine thread or a mounting attachment.
Seal Gland: The cylinder head is fitted with seals to prevent the pressurized oil from leaking past the interface between the rod and the head. This area is called the seal gland. The advantage of the seal gland is easy removal and seal replacement. The seal gland contains a primary seal, secondary seal/buffer seal, bearing elements, wiper/scraper, and static seal. In some cases, especially in small hydraulic cylinders, the rod gland and the bearing elements are made from a single integral machined part.
Seals: The seals are considered/designed as per the cylinder working pressure, cylinder speed, operating temperature, working medium, and application. Piston seals are dynamic seals and can be single-acting or double acting. Generally speaking, Elastomers seals made from nitrile rubber, Polyurethane or other materials are best in lower-temperature environments, while seals made of Fluorocarbon Viton are better for higher temperatures. Metallic seals are also available commonly used cast iron for seal material. Rod seals are dynamic seals and are generally single-acting.
The compounds of rod seals are nitrile rubber, Polyurethane, and Fluorocarbon Viton. Wiper/scrapers are used to eliminate contaminants such as moisture, dirt, and dust, which can cause extensive damage to cylinder walls, rods, seals, and other components. The common compound
for wipers is polyurethane.
Metallic scrapers are used for sub-zero temperature application, an application where foreign material can deposit on rod. The bearing element/wear bands are used to eliminate metal-to-metal contact. The wear bands are designed as per the side load requirements. The primary compounds for wear bands are filled PTFE, Woven fabric-reinforced polyester resin, and bronze.
