Mechanical buffing systems have a motor-driven shaft to which the buff wheel is applied. In addition, most machines will have a positioning mechanism, a finishing lathe, and workpiece-specific fixtures.

Positioning Mechanism: Automated buffing machines orient parts against the media by mechanical methods to duplicate or replace human motions. They rotate, oscillate, tilt, and index the wheel and/or the workpiece.

Finishing Lathe: The finishing lathe is a device located in relation to the positioning mechanism. It allows a buff wheel to contact one of more surfaces of the workpiece at predetermined locations.

Fixturing: The workpiece fixture or tooling is used to position a part during the buffing cycle. Buffing machines can incorporate single or multiple fixtures. Fixtures can also be designed to automatically reorient a workpiece during the buffing cycle.

Buffing fixtures are unique to each part being processed, although some may be adapted to an assortment of similarly shaped parts. The design of fixtures is extremely important. Unless a part can be fixtured properly at a reasonable cost, the economical utilization of finishing equipment cannot be justified.

Types of the Buffing and Finishing Machines

Buffing machines fall within three broad categories: manual, semiautomatic, and fully automated

Manual Machines

Manual buffing machines are used in low-volume applications and applications involving the buffing of extremely complex workpieces. Manual machines, when used in conjunction with the proper buff
wheel and buffing compound can be manipulated.

Semiautomatic Machines

Semiautomatic buffing machines are used in lower-volume applications where a single finishing operation is performed on a variety of parts. Initial investment and fixturing and operating costs are low. Semiautomatic finishing machines can be used with a single- or double-end lathe.

One operator can be employed to load, unload, and operate the equipment. Semiautomatic machines hold the workpiece and present it to the buff wheel. A timed cycle controls dwell and retraction. Only one fixture is required for each machine for each type of part finished. Because the machine supports the part, operator fatigue is minimized. Various types of rotation also can be performed, depending on the type of semiautomatic machine selected.

Production of semiautomatic buffing machines depends on part configuration and the degree of finishing required. By using a double-end jack with two semiautomatics, an operator can load one machine while the other is finishing a part. This can double production without increasing labor costs.

Fully Automatic Machines

Fully automatic machines are used in high-volume applications where multiple surfaces of a workpiece must be finished. The two most common types of automatic buffing machines are rotary automatic and straight-line machines.

Rotary Automatic Machines

Rotary Automatic Machines for Buffing and Finishing
Rotary Automatic Machines for Buffing and Finishing

Rotary machines have round tables with finishing heads located around the
periphery of the table. This type of machine is typically used to finish simple, round parts requiring high production. The number of finishing heads and production determine the size of the rotary.

The table of the rotary machine can move continuously or index to start, stop, dwell, and then start again, with the length of the dwell controlled by a timer. The configuration and area of the product to be finished determine which is best. Production is higher on a continuous rotary machine because the table does not stop rotating.

On an indexing rotary machine, because of the stop, dwell, and start cycle, production is lower. Parts that have surfaces that are difficult to reach and require more dwell time in certain areas may be finished on an indexing rotary machine to obtain the dwell time necessary.

On each table, there are rotating spindles on which the parts are fixtured for the finishing sequence. Rotary tables may have a greater number of fixtures than indexing tables since the production and simple configuration make it more appropriate to be run on a continuous
machine due to the ease of reaching all surfaces.

Straight Line Machines

There are various types of straight-line automatic finishing machines. Normally, linear workpieces are finished on straight-line machines. Straight-line machines also can be used to finish round parts if extremely high production is required. There is less limitation on workpiece size as with rotary equipment.

With straight-line automatic machines, finishing heads can be placed on both sides of the machine. In addition, various heads can be incorporated into the system for buffing and polishing. With rotary equipment, the outside periphery of a rotary table is used. Various types of straight-line machines include:

  • Horizontal return straight line
  • Narrow universal straight line
  • Over and under universal straight line
  • Reciprocating straight line
  • Open-center universal
  • The size or length of these straight-line machines can be designed and built to accommodate the desired end result; floor space is the only major limitation. Each machine normally requires only one operator for load/unload. All operations of these machines are controlled from a push-button panel located near the operator for starting, stopping, and controlling various functions.

Surface finishing operations are essential processes applied to sheet metal parts to enhance their appearance, functionality, and durability. These operations involve the removal of imperfections, smoothing of surfaces, and application of protective coatings.

Mandrel benders are similar to the rotary draw bender but use an additional wiper die on the outside of the tube and a mandrel which is inserted into the tube and remains inside the tube during the bending process. This internal mandrel helps to support the shape of the wall when bending. Typically a mandrel bender is needed when bending thin wall tubing to a radius much tighter than the material can bend without collapsing or distorting.

3 Roll Bending

3 Roll Bending
3 Roll Bending

Three-roll bending, also known as roll bending or roll forming, is a versatile and efficient method for bending plates, sheets, and bars into various shapes and curves. It is widely used in various industries, including construction, shipbuilding, automotive manufacturing, and metal fabrication. The process involves passing the material through a series of three rolls, each with a slightly different angle, gradually deforming the material into the desired shape.

Working Principle of 3-Roll Bending

The core of the 3-roll bending process lies in the precise alignment and controlled rotation of the three rolls. The material, typically a plate, sheet, or bar, is fed into the machine and positioned between the rolls. As the rolls rotate, they apply pressure to the material, causing it to bend and conform to the curvature of the rolls.

  1. Top Roll Adjustment: The top roll is adjustable, allowing for precise control of the bending radius. By adjusting the top roll’s position, the machine can create a wide range of shapes, from gentle curves to tight bends.

Three-roll bending has become an indispensable tool in various industries, offering precision, versatility, and the ability to shape various materials efficiently. These machines play a crucial role in the production of durable, functional, and aesthetically pleasing structures and components. As technology advances, 3-roll bending machines are continuously evolving, incorporating innovative features that enhance their capabilities and expand their applications.

3-roll bending is also used for producing workpieces with large bending radii. The method is similar to the ram bending method, but the working cylinder and the two stationary counter-rollers rotate, thus forming the bend. Normally there are 2 fixed rollers and one moving roller and the workpiece is passed forward and backward through the rollers while gradually moving the working roller closer to the counter rollers which changes the bend radius in the pipe.

This method of bending causes very little deformation in the cross-section of the pipe and is suited to producing coils of the pipe as well as long sweeping bends like those used in powder transfer systems where large radii bends are required

Bending Springs

In the context of pipe bending, bending springs are tools used to provide support and prevent distortion or collapsing of pipes during the bending process. These springs are typically made of materials with high strength and flexibility, such as spring steel or other alloys. They are designed to fit inside the pipe being bent and offer resistance against deformation.

Here’s how bending springs are commonly used in the pipe bending process:

Purpose of Bending Springs

  1. Preventing Collapse:
    • Bending springs are crucial when bending thin-walled pipes or tubes that might collapse or deform under the force of the bending machine. The spring supports the inner wall of the pipe, maintaining its shape during the bending process.
  2. Maintaining Roundness:
    • For pipes that need to maintain a specific round shape, bending springs help to evenly distribute the bending force, reducing the risk of ovalization or distortion.
  3. Minimizing Rippling:
    • Bending springs help prevent the formation of ripples or wrinkles on the inner radius of the bend, ensuring a smoother and more uniform bend.

Steps in Using Bending Springs

  1. Selecting the Right Size:
    • Choose a bending spring that matches the diameter of the pipe being bent. It should fit snugly inside the pipe.
  2. Inserting the Bending Spring:
    • Slide the bending spring into the pipe before placing the pipe in the bending machine. Ensure that the spring is evenly distributed along the length of the pipe.
  3. Bending Process:
    • The pipe, along with the inserted bending spring, is then fed through the bending machine. The bending spring provides internal support, preventing the pipe from collapsing or deforming during the bending process.
  4. Removing the Bending Spring:
    • Once the bending process is complete, the pipe is removed from the machine, and the bending spring is taken out. The spring may need to be cleaned or inspected for any signs of wear.

Considerations

  1. Material and Size:
    • Bending springs should be made of materials that offer flexibility and strength. The size of the spring must match the diameter and material thickness of the pipe.
  2. Spring Design:
    • The design of the bending spring is critical. It should provide sufficient support without causing excessive friction during the bending process.
  3. Material Compatibility:
    • Ensure that the material of the bending spring is compatible with the material of the pipe being bent. This is particularly important for preventing any chemical reactions or contamination.
  4. Quality Inspection:
    • Regularly inspect bending springs for signs of wear or damage. Damaged springs can lead to suboptimal bending results or cause damage to the pipe.

Bending springs are valuable tools in the field of pipe bending, contributing to the production of accurate, uniform, and distortion-free bends in pipes and tubes. Proper selection and use of bending springs are essential for achieving high-quality results in the pipe bending process.

These are strong but flexible springs inserted into a pipe to support the pipe walls during manual bending. They have diameters only slightly less than the internal diameter of the pipe to be bent. They are typically only used for bending 15-to-25 mm soft copper pipe (used in household plumbing). The spring is pushed into the pipe until its center is roughly where the bend is to be. A length of flexible wire can be attached to the end of the spring to facilitate its positioning and removal.

The pipe is generally held against the flexed knee, and the ends of the pipe are pulled up to create the bend. To make it easier to retrieve the spring from the pipe, it is a good idea to bend the pipe slightly more than required, and then slacken it off a little. They are less cumbersome than rotary benders but are not suitable for bending short lengths of piping when it is difficult to get the required leverage on the pipe ends. Bending springs for smaller diameter pipes (10 mm copper pipe) slide over the pipe instead of inside.

Heat Induction Bending of Tubes

In the case of heat induction, a coil is placed around the pipe. The coil heats a section of the pipe to a temperature between 430 and 1,200 °C. The temperature depends on the material. The pipe passes through the coil at a gradual rate while a bending force is mechanically applied to the pipe. The pipe is then quenched with either air or water spray. The products thus obtained are generally of high quality, but cost significantly more to produce.

Physical Effects on Pipe and Tube from Bending

Heat induction bending is a precise and efficient method for bending tubes made of various materials, including metals, plastics, and composites. It utilizes the principles of electromagnetic induction to heat a localized area of the tube, allowing it to be deformed into the desired shape without affecting the integrity of the rest of the tube.

Working Principle of Heat Induction Bending

The process of heat induction bending involves:

  1. Coil Placement: An induction coil is placed around the section of the tube to be bent. This coil generates a strong electromagnetic field.
  2. Eddy Current Generation: When the tube is placed within the electromagnetic field, eddy currents are induced within the metal walls of the tube. These eddy currents generate heat, primarily in the localized area directly beneath the coil.
  3. Localized Heating: The localized heating softens the tube material, making it more pliable and easier to bend.
  4. Bending Force: A bending force is applied to the heated section of the tube, causing it to deform into the desired shape. The bending force can be applied manually or through mechanical means.

Advantages of Heat Induction Bending

Heat induction bending offers several advantages over other bending methods:

  1. Precision: The localized heating allows for precise control of the bending process, ensuring consistent and accurate bends.
  2. Clean Heating: The heating process is clean and non-contact, preventing surface damage or oxidation of the tube.
  3. Versatility: Heat induction bending can handle a wide range of tube materials, including metals, plastics, and composites.
  4. Efficiency: The localized heating and rapid bending process make heat induction bending an efficient method for shaping tubes.
  5. Reduced Springback: The controlled heating and cooling process minimizes springback, the tendency of the tube to return slightly to its original shape after bending.

Applications of Heat Induction Bending

The versatility of heat induction bending makes it suitable for a wide range of applications:

  1. Aerospace: Heat induction bending is used to create precision bends in tubes used in aircraft structures, ensuring structural integrity and aerodynamic performance.

These machines are indispensable tools in various industries, contributing to the creation of durable, functional, and aesthetically pleasing products. As technology advances, heat induction bending machines are continuously evolving, incorporating innovative features that enhance their capabilities and expand their applications.

Depending on the bending method used and the material qualities of the pipe or tube being bent some of the following physical effects can be seen after bending:

  • Wrinkles on the inner side of the bend
  • Stretching of the wall on the outer side of the bend
  • Thinning of the wall thickness on the outer side of the bend
  • Deformation of the cross-section of the pipe or tube causes it to reduce and form an oval shape.

Mechanical Effects on Pipe and Tube from Bending

6. Fatigue Resistance

  • Effect: Bending can influence the fatigue resistance of the material. The presence of bends may create stress concentration points, affecting the material’s ability to withstand cyclic loading.

7. Buckling and Wrinkling

  • Definition: Buckling is the sudden bending or distortion of the material under load, and wrinkling is the formation of folds or creases.
  • Effect: Inadequate support or improper tooling can lead to buckling or wrinkling of the material, affecting its structural integrity.

8. Springback

  • Definition: Springback is the tendency of the material to return to its original shape after bending.
  • Effect: Springback can impact the accuracy of the final bent shape. Compensating for springback is essential to achieve the desired geometry.

9. Material Hardening

  • Effect: Bending can result in localized work hardening, especially on the outer radius of the bend. This may affect the material’s machinability and formability.

The mechanical properties of the materials are also altered during the bending process.

  • Cold forming causes yield and tensile strengths to rise by 10%
  • Elongation may decrease by as much as15%
  • Bending of the pipe will also tend to result in distortions of the cross-section. The distortions are greater the tighter the radius of the pipe.

The following are general guidelines for hydraulic pipe and tube bending
equipment, as there are many different suppliers of bending equipment it is not possible to provide a specific checklist. This information does not replace the manufacturer’s instruction guide, it is meant only to acquaint the operator with some basic functions and safety tips that he/she must be aware of. Equipment, particularly hydraulic power sources, vary considerably in their control and safety arrangements, and therefore it is important to verify that the actual equipment used is set up correctly.

  • Before each use, inspect the Pipe Bender for bent or damaged components.
  • Check that the bending die is correctly seated on the ram and that the roller shafts are fully engaged in the frame and pinned before operating the hydraulic unit.
  • Regularly wipe down and clean the tool to keep it in the best condition.
  • Keep hands away from die and rollers when bending pipe.
  • Use a qualified person to lubricate and maintain the hydraulic unit.
  • Confirm that the recommended hydraulic oil is used during maintenance.
  • DO NOT top-up the system with brake fluid. Use hydraulic oil only.
  • DO NOT operate the pipe bender if damaged.
  • DO NOT exceed the rated capacity of the hydraulic unit
  • DO NOT use the pipe bender for purposes other than that for which it is intended.
  • DO NOT alter the settings of the pressure control valve.
  • When not in use, store the tool in a clean, dry, safe location out of reach of children and other unauthorized persons.
  • Ensure that you read, and understand safety instructions before operating the pipe bender.
  • With the hydraulic unit release valve open and the ram fully retracted, fit the appropriate-sized die to the ram.
  • Move pipe rollers and shafts to appropriate holes in the frame and ensure that shafts are properly fitted and secured using hitch pins.
  • Introduce the pipe between the die and rollers, positioning it so that the center of the required bend in the pipe is over the center of the die.
  • Close the release valve and pump handle until the required degree of bend is achieved.
  • Using the end of the handle, open the release valve and the ram will retract under spring tension.
  • Annually, replace hydraulic oil using correctly rated hydraulic jack oil.
  • With the ram fully retracted, drain and refill to the bottom of the filler plug hole.
  • When connecting the high-pressure hose with male and female quick connects ensure that both ends are clean and clear of dirt and contamination and that there is no pressure in the system before making the connection.
  • Maintain product labels and nameplates. These carry important safety information
