HyperCyl Case Study: Control Arms and Snap Ring Solution

HyperCyl was tasked with an application that involved the installation of both bushings and ball joints on a control arm that included secondary retention of the ball joint. Thus, the HyperCyl patented Snap Ring Mechanism was developed in 2017.

What Control Arms Do

*Maintaining wheel alignment: The control arm helps to keep the wheels of the car aligned properly with the frame or body of the car. This is important for ensuring that the car drives smoothly and handles well.

*Absorbing shock: As the car travels over bumps and rough terrain, the control arm helps to absorb the shock and vibrations that are created. This helps to provide a comfortable ride for passengers and protects the car’s other components from damage.

*Supporting weight: The control arm supports the weight of the car and helps to distribute it evenly across the suspension system. This helps to prevent the car from leaning too much during turns or when going around corners.

*Controlling wheel movement: The control arm helps to control the movement of the wheel, ensuring that it stays in the correct position and doesn’t wobble or move excessively. This is important for maintaining the car’s stability and safety

Anatomy of a Control Arm

*There exists an Upper Control Arm (UCA) and Lower Control Arm (LCA) with connecting tie-rods from each Ball-Joint to the steering system, be it a steering wheel for tractors/automobiles/lawnmowers or handlebars for 4-wheel ATV/UTV.

*Control Arms for all types of vehicles typically follow the same layout and arrangement; each requiring (2) Bushings and (1) Ball-Joint to stabilize the wheel and provide direct connection to your steering mechanism.

*Press Fitting the bushings is typical and the interference fit between the bushing and machined arm will retain the bushing in place. These can be pressed OUT when needed for vehicle maintenance.

*Ball-Joints require a similar Press-Fit into the cast/machined arm however automotive vehicles require a means of secondary retention due to vehicle safety standards and/or future replacement availability.

Secondary Retention of the Ball Joint

Secondary retention of the ball-joint can be accomplished by either a deformation of the ball-joint body, or by use of a heavy-duty retaining clip otherwise known as a snap-ring.

HyperCyl provide a means for installation of BOTH bushings and ball-joints but also can provide the means for secondary retention with our Patented Snap-Ring mechanism. This device is used in automated or semi-automated installation of the snap-rings for medium to high volume assembly production.

The Snap-Ring mechanism works as follows:

*The snap-ring is preloaded on top of nest (via robot or pick-n-place or manually by operator), the HyperCyl actuator extends down contacting the ball joint thereby pushing the ball joint bottom surface INTO the snap-ring.

*As the ball joint contacts the inner ball, the (3) fingers expand opening the snap ring as the pressing motion continues.

*Once the snap-ring is at the proper level the fingers release, and the snap-ring is properly located within the ball joint groove securing it from accidental removal. The ram can now retract to home, releasing the assembly for offload.

HyperCyl Case Study: Removing Hydraulics from the Equation for Assembly

A major U.S manufacturer of braking and suspension components contacted HyperCyl® to increase quality of their finished products and free up floor space for a new assembly line. The OEM was experiencing persistent assembly interruptions due to their Hydraulic Dial Tables’ inability to monitor & relay actual insertion forces & distances. Additional floor space was also necessary to make room for a new product assembly line, so removing the noisy pumps, balky accumulator tanks, high-heat motors and leaking hydraulic lines associated with the antiquated hydraulics was essential.

HyperCyl® retrofitted the entire Dial Table, removing all hydraulic cylinders and replacing with Hydra- Pneumatic cylinders operated by simple pneumatic valves. Each dial location now includes the integral LVDT and Load Cell options demonstratively called IntelliCyl® along with the HyperView-Press® Signature Analysis Monitor. The HyperCyl® solution actively measures the stud & bearing insertion depth by establishing a series of “windows” around critical points of the operation, namely the part stack-up (part contact) and final depth. ONLY when critical stack up “window” was confirmed would high pressure then activate to finalize the part. This provided key measurement of the operation ultimately reducing in-process part non-conformance to near-zero.

**1. An infeed conveyor provides the subassembly to the gripper location. 2. From there, the gripper will load the seal into the nest cavity. 3. The HyperCyl cylinder with IntelliCyl force/distance feedback assembles the filaments and forms the final shape. 4. From there, only when the part is validated and passes a series of inspections it is automatically able to be removed from the cell into a container. 5. Any parts that do NOT pass inspection are automatically redirected into a bad parts bin for scrap. 6. Isolating these good and bad parts is crucial for the prevention of part-non-conformance.

Using Cleaner Technology for a Brighter Factory

Outdated Hydraulic systems require constant maintenance and high cost pumps, Pure Pneumatic systems lack the force and controllability, Arbor Presses and Hammers exhaust my employees, Flywheels are dangerous; if these problems sound familiar you’re not alone.

“Punching and Shearing” Tips and Tricks

Aries Engineering/HyperCyl is a diversified manufacturer of Hydra-Pneumatic Cylinders, Servo Actuators, Presses, Pierce Units and Joining Systems designed for use in a wide range of assembly
and forming applications. HyperCyl has a place in virtually every segment of industrial production. HyperCyl has a proven track record in thousands of applications as a clean, quiet, reliable, self-contained power source utilizing only compressed air to generate ample output forces from 3kN – 1,780kN.

The formula to calculate punching force is quite simple:

Force = Hole Perimeter (length of cut) x Material Thickness (aluminum, steel, stainless) x Shear Strength or Tensile Strength (depends on type of punch being used). You must make sure that you keep your units consistent between Metric and Imperial.

Metal Forming

Forces required for metal piercing can be calculated as follows:
L= Length
T= Thickness of Material
S= Shear Strength of Material

L x T x S = Force Required

(stripping force= 10% of Pierce Force)

Stripping force is the force required to typically remove or retract the punch after it has pierced the material.

Example:

3/8 ” (.375″) hole through .032″ thick CRS (cold rolled steel)
L= 1.178 (.375 x 3.141)
T= .032
S= 55,000

1.178 x .032 x 55,000= 2090 lbs.

Here are some helpful tips and tricks for punching and shearing applications:

*While the ultimate Tensile strength is used for initial calculations for flat punch designs, the formula for using full tensile strength is applied at the onset to establish a WORST-CASE scenario for sizing our cylinders. Real life tensile can vary based on mold/forming time, cooling time, work hardening (if applicable) and a host of other miscellaneous factors. We don’t see as much variation with Aluminum castings as we do with steel.

*We can provide parts-testing data and extrapolate from our testing for a 0.25”, 0.375”, and 0.500” nominal punch holes to determine the actual tensile/shear strengths and calculate real life forces, factoring in the flat punch or shear punch designs.

*Not everyone uses Shear in the punch head, MOST use a flat punch so it can be sharpened easily and reused for many years. When using SHEAR in your punch head, the Shear Strength can be used for force calculations.

*In all piercing applications, a “stripper” or positive force on the part DURING punching operation should be considered so the part can remain located in nesting during retraction of the punch from part. If absent from your design, the part will retract with the punch during retract.

*There are numerous versions of shearing punch designs which directly correlate to forces required:

-High angle, straight cut (think scissors)
-Rooftop
-Inverted Rooftop
-Inverted Rooftop
-Double Valley
-JK Shear (flat punch, using Tensile strength, NOT shear strength)

HyperCyl Spotlight: UTV Applications

Roll Cage Pierce/Form: Typical End-forming and tube Piercing of UTV Roll Cage requires an Approximate Force Range 5-40 Tons depending on the details. Piercing requires internal expanding mandrels to reach long distances inside the tube body. End-forming varies dramatically based on the needs of each application but involves forming the end of tubes to various GD&T for mounting, safety, and other items. Best used with IntelliCyl for force/distance monitoring to ensure Quality is maximized.

REAR TRACK ARM BUSHING INSERTION: From the basic to the complex, we have seen it all regarding bushing insertions. Simultaneous running of LH & RH parts simplifies tooling setup and reduce part-to-part rates dramatically. Approximate Force for 1.500” – 2.500” bushing diameter ranges from 8-Tons to 15-Tons depending on the interference fit between the sleeve ID and bushing OD. Lubrication is sometimes necessary to reduce forces and ensure a good insertion. Lubrication is applied to the ID of sleeves or OD of bushing which reduces chatter during the installation process and provides a more accurate press-in.

WHEEL HUB BEARING AND STUD INSERTION: Wheel bearings are a critical function in the construction of UTV’s as they must be properly installed and seated or risk the longevity and ride comfort to the vehicle. Likewise, the wheel studs are installed with special fastening technology using serrations on the stud to withstand torque-out when attaching the wheel nuts. Force/ distance monitoring is almost always required for these critical components.

CONTROL ARM BUSHING INSERTION: Aries Engineering specializes in Control Arm construction due to our innovative power heads in Servo and Hydra- Pneumatic Self-Equalizing units.
These equalizing units are a necessity due to the small window between bushing sleeve ID’s. Backing up each sleeve prior to installation is required so as not to damage or twist the arm during bushing installations. Approximate Force Ranges from 8-20 Tons utilizing our IntelliCyl option for force/distance monitoring.

BALL JOINT INSTALLATION: Ball Joint installations typically require secondary retention to meet today’s safety requirements. Aries Engineering has patented a proprietary Snap-Ring installation process that automatically installs the Ball Joint then the snap-ring within a single process. Ordinarily this is a very manual process with handheld retaining ring pliers or circlip
pliers to ensure the clip is seated 100% and 360-degrees around the circumference. Approximate Force per Ball Joint can be as high as 20-Tons. IntelliCyl is required for force/distance monitoring of this critical component during the installation process.

PLASTIC FASCIA PIERCING/ DEGATING: Multiple components within the UTV require post-mold piercing to ensure proper alignment of fasteners and attachment points that cannot be done during the molding process. Piercing gas-cap holes to fog-lamp holes, hitch slots to lightening holes, we have Servo and Hydra-Pneumatic power units available that are well-suited. When a substance is melted and poured into casting molds, channels called gates allow the material to flow into the hollow spaces of the mold to form into a solid part. Removing the material that hardens in the channels so that just the finished piece remains is known as degating. We have developed methods to ensure this degating only removes excess material without damage to the end-product.
