Four Ways We Hold Things Together

We live in a world where things are put together. The computer you’re using, the desk it’s on, and the chair you are sitting in have all been assembled. At Orbitform, we specialize in permanent part assembly, processes like orbital forming, impact riveting, roller forming, and hot upset riveting and forming. These four processes are all unique and have their own strengths, weaknesses, and qualities. They have major advantages in assembling parts that don’t need to be taken apart, both in reliability and longevity. But what are they? Why do these processes excel when compared to non-permanent fastening solutions? If your product doesn’t need to be taken apart, consider these reasons to switch to permanent assembly.

Permanent Part Assembly Advantages

  1. Reduce the Costs of Fastening Hardware
  2. Leave behind the retaining rings, threaded fasteners, nuts, washers, and cotter pins. With permanent part assembly, the part and the fastener are formed together, creating a secure and permanent bond without the use of extra unnecessary hardware.

  3. Reduce the Costs of Machining Operations
  4. Save money by avoiding costly operations like machining grooves and threads, drilling and tapping holes, etc. With the time saved in these areas, quality and throughput is increased.

  5. Reduce the Costs of Assembly Operations & Cycle Time
  6. It’s the easy solution when it comes to reducing cycle times: reduce the number of hardware parts and operations that need to be done to a part. This could be installing a retaining ring or cotter pin, or driving a screw or a nut. Permanent part assembly means shorter cycle times and more parts moved down the line.

  7. Superior Retention
  8. Compared to cotter pins, retaining rings, and Loctite® adhesives, permanent part assembly has a much better retention level. There’s a reason the word permanent is in the title.

  9. Improved Aesthetics
  10. If you’re concerned with how your finished parts look, permanent processes deliver some of the best aesthetics. As we mentioned earlier, loose the retaining rings and cotter pins; make it look clean and finished with a formed head instead.
    There is not a “one size fits all” solution for permanent part assembly. But you could start receiving these benefits by switching your assembly process. If your product doesn’t need to be taken apart, for shipping, maintenance, or repair, then consider switching to a process like orbital forming, impact riveting, roller forming, or hot upset riveting. Orbitform is an expert in delivering unbiased approaches to help our customers find the very best process to fit their needs.

Articulating vs. Static

Orbitform has been designing and building assembly equipment since 1984. One of the areas we have specialized in is Roller Forming. We have two different types, articulating and static. Both of these serve their own purposes, and can offer you an assembly advantage.
Roller Forming is a non-impact process using a spinning Roller Head with two or more rollers to apply a symmetrical force to form the part. Roller forming is used for flaring, forming a lip, crimping, or forming a groove in cylindrical parts too large for other processes. This is where the two types of roller heads come in.

Static Roller Heads

Static roller heads are used when forming a lip around a cylindrical part. These heads have spinning rollers that use down-force from one of Orbitform’s standard powerheads to create an aesthetically pleasing lip on a surface. These roller heads are both consistent and efficient, and the non-impact nature combined with precision and accuracy allow for the forming of delicate and brittle materials. Through use of an o-ring or gaskets, it is possible to form sealed caps on the end of cylindrical parts.

Articulating Roller Heads

Articulating heads are most often used for either forming a groove in a part or when there are obstructions to clear in order to form a lip. These parts use 360o Contact while forming, so there is consistent action while forming the part. These roller heads can deliver forming forces up to 5,000 lbs. @ 100 psi. These roller heads can bring new advantages to your forming process.

The Assembly Advantage

Orbitform has been delivering assembly solutions for manufacturing since 1984. With experience in riveting, forming, conveyors, assembly systems, and welding, we have the ability to offer you an unbiased assembly solution.

Assembly Analysis
Nov 27

At Orbitform, we are dedicated to helping our customers increase throughput and reduce costs. One of the ways which we do this is through multi-form heads. These options operate similar to Orbital, but make it possible to form multiple rivets on the same part or rivets across multiple parts at the same time. These heads are used throughout the assembly automation process, providing advantages like cost reduction, quality increase, and cycle time reduction for high volume production. Multi-forming is typically done with one of two options: Multi-Spindle and Multi-Point. Both of these options allow the possibility of forming multiple rivets

Multi-Spindle Heads

Multi-spindle heads use an Orbital Powerhead to produce forming motion and force. Multiple Orbital heads attach to the multi-spindle head, forming multiple rivets at the same time. These rivets can either be across multiple parts or on the same part. Center distances for multi-spindle applications are dependent on rivet size and corresponding Orbital head used for forming. Multi-spindle forming is not restricted to a single plane since separate spindles and orbital heads are used for each rivet. These heads can be designed for different heights in relationship to one another.

Run more parts per cycle, increase throughput, and reduce costs.

Multi-Point Heads

Multi-point heads use fixed center forming peens on a single eccentric driven head to form rivets set close together. Multi-point applications form multiple rivets on the same part to reduce cycle time and part handling, leading to more throughput and higher efficiency. Anyone manufacturing small parts with rivets set close together can benefit from multi-point forming. Center distances for applications can range from as little as .188” (4.7mm) to 3” (76 mm).

The Assembly Experts

Orbitform is an expert in assembly solutions. Multi-point and multi-spindle are just the beginning when it comes to optimizing your assembly process.

Impact Riveting
Nov 27

When customers approach us with rivets that are delicate, long, or unsupported, we often turn to radial forming as a solution. Radial riveting and forming, also known as Radial, is similar to the Orbital process, but the material is displaced from the center outward in a rosette or rose curve pattern; this creates less side force than the orbital process. Radial is ideal for forming small or delicate parts. Radial heads are also available with the standard or long reach peen options, giving a wider range of forming possibilities.

Unique Applications

Radial Form is for customers with unique or very light duty applications. It is also available as a “standard option” for new machines and systems and designed to retrofit existing Orbitform machines by means of a spindle change out. Additionally, Radial has been designed to accommodate an integral load cell into the spindle package. This allows radial to provide the same process monitoring capabilities as the rest of the Orbitform product line.

At Orbitform, one of our specialties is in Orbital Forming and Riveting. Orbital forming and riveting is a cold forming process using a peen tool held at a fixed angle to create a sweeping line of pressure around a rivet, progressively forming the rivet throughout the process.

This peen is crucial to the forming process, making contact with the part being forming and doing the actual forming work. The peen fits into the orbital head and is typically held in place by a set screw.

There are a wide variety of standard peens that are used with orbital heads, each with a different purpose. Some ensure a certain aesthetic appearance while others are capable of flaring or crimping. Each peen is designed specifically for each customer part, developed by our engineers to custom fit the specific application.

The peen becomes the key to forming high quality parts. Orbitform will ensure that your peens and tooling will produce top quality parts with consistency. We are the experts in permanent part assembly, and we will put our knowledge to work for you. Orbitform…solutions delivered.

If you are struggling to permanently assemble tubular or large diameter parts, Orbitform’s Roller Forming process may be the solution. Roller Forming is a non-impact process using a spinning Roller-head with two or more rollers to apply a symmetrical force to the part. Roller Forming is used for flaring, forming a lip, crimping, or forming a groove in cylindrical parts too large for other processes. Assembly applications include: water pumps, bearings, ball joints, air bag canisters, electrical sensors, fuses, solenoids, and parts where a groove or lip is needed, such as sealing the end of a tube.

An automotive part supplier wanted to reduce the cost and weight of their water pump by converting its cast iron housing to cast aluminum. Originally the bearing was press-fit into the housing. The result was lighter, but thermal expansion was greater. Repeated heating and cooling caused the bearing to walk-out. The customer tried adhesives to retain the bearing, but this added an addition expense and an additional process that was messy.

Orbitform Engineers a Solution

Orbitform’s Applications Engineers worked with the customer to design a retaining feature that could be formed using Orbitform’s Roller Forming process to permanently retain the bearing. A custom static two-roller tooling head was developed and tested using Orbitform’s standard Powerhead. For this application our engineers determined a rotational speed of 400 rpm was optimal when combined with the downward force of the Powerhead. The customer verified the result using a push-out test, which caused the cast aluminum housing to fail without pushing the bearing past the formed retaining lip.

A custom designed fixture held the housing assembly, and a thru-spindle pressure pad held the bearing in place. Process monitoring included bearing presence confirmation, a load cell to monitor force, and LVDT to monitor the Powerhead’s stroke position. Three interchangeable Roller-Heads allowed the customer to used the same machine for three different water-pump assemblies. Safety equipment included a light curtain, guarding, and opto-touch activation buttons.

As a general rule, 90% of Roller Forming applications are between 3/8” and 6” in diameter. Wall thickness can vary from 1/32” to over 1/4" depending on the type of material. The Roller-Head RPM and advance rate are controlled by Orbitform’s standard Powerhead to precisely form the material. The Powerhead can also be configured with an integrated Load Cell and LVDT for process monitoring and control, along with a thru-spindle pressure pad for part clamping during the forming process. For static Roller-Heads, typical cycle times range from 3-5 seconds depending on the application.

Here at Orbitform, we recently developed a unique riveting process called Hot Upset. This rivet/forming solution uses force and heat to form rivets or part tenons, providing greater strength, increased hole-fill, improved resistance to push-pull forces, and an overall tighter joint, due to material contraction during cooling.

Form with Heat and Pressure

Similar to electro-forging, the headed material becomes malleable and collapses under pressure applied by the Powerhead. With this process it is possible to form a round fastener into a square hole, creating a high-torque joint. Our customer, an automotive part manufacturer, needed to assemble a product with hardened rivets, each with a long tenon stick-out. To meet their production requirements, we needed to form two rivets per machine cycle. We examined both Orbital and Radial Forming options in our applications lab, but due to the extreme hardness of the rivets, final form characteristics did not meet our customer’s specifications. Also, some samples showed signs of cracking, which was unacceptable in this application. We then tested our Hot Upset forming solution, which resolved the forming challenges.

Solutions Delivered

Orbitform designed and built a custom Hot Upset system. The design included two standard Orbitform modular Powerheads, the same Powerheads used in our Orbital, Radial, and Roller Forming products. Using standard Powerheads instead of traditional weld cylinders eliminated the need for an external air/oil tank and intensification valve. To stabilize the customer’s part during the forming process, the system was outfitted with a part clamping pressure pad. To verify a quality form, process monitoring included an LVDT, load cells, and Powerhead advance and retract sensors. The customer’s safety specifications included light curtains, guarding, and palm button activation.

Hot Upset typically has a 3-4 second cycle time, which is generally slower than Orbital, Radial or Impact Riveting. In addition, hot parts require special handing considerations. We offer both AC and DC Hot Upset systems. In the case of our customer, we built a DC system for its power consumption savings versus the lower initial cost of an AC system. DC powered systems are more efficient and precise than their AC counterpart, but come at a higher price. Cost of ownership includes power consumption and tooling electrodes. Hot Upset systems also require a chiller to maintain optimal tooling temperature.

Our Hot Upset process could help you in your assembly process. At Orbitform, we are experts in assembly processes. To learn more about permanent part assembly,  or download our full white paper text.
