What are the two main types of roller forming?
Orbitform offers Static and Articulating Roller Forming, each designed for specific application needs based on part geometry and material characteristics.
When is articulating roller forming typically used?
Articulating roller forming is ideal for applications requiring an O-ring groove, undercut form, or when the part’s sidewall is sensitive to downward force, which could cause bulging, buckling, or splitting.
Does a part need to be round to be roller formed?
No, roller forming can accommodate oval shapes, provided the roller width ensures contact with the area to be formed.
Does a part need to be a complete 360-degree circle for forming?
No, roller forming can work on parts with interruptions, such as notches or other features, allowing for flexibility in part design.
What is the maximum stroke of an articulating roller form head?
The articulating roller form head has a maximum stroke of 7/8”, accommodating various part heights.
What pressure pad options are available for roller forming heads?
We offer mechanical spring-loaded and thru-spindle pressure pad options, each suited for different forming needs.
What is the purpose of a thru-spindle pressure pad?
The thru-spindle pressure pad applies a clamp or preload to the assembly before and during forming, ensuring consistent contact and reliable results.
What feature supports the thru-spindle pressure pad in the powerhead?
An offset motor drive is necessary to create clearance for the thru-spindle pressure pad, enabling optimal function.
What is the largest rod diameter for use with a thru-spindle pressure pad?
The maximum rod diameter for this assembly is 5/8”, based on spindle clearance.
What is the standard rotation speed for roller forming heads?
Typical rotation speed ranges from 300 to 600 RPM, adjusted based on material type, hardness, and part geometry.
What can a roller head be mounted to?
Roller heads are typically mounted to pneumatic, servo, or hydraulic powerheads, and occasionally to CNC machines, drill presses, or lathes.
What equipment options does Orbitform offer for roller forming?
Options include load cells, LVDTs, and pressure pads for enhanced control and monitoring during forming.
Can force and distance be monitored in articulating roller forming?
Yes, we use an internal draw-bar actuating cylinder package in the powerhead to track force and distance.
What direction does the force apply in articulating roller forming?
In articulating roller forming, force is applied radially, or inward, to form the part.
Can articulating roller heads be used in static applications?
Yes, articulating roller heads can be used in servo applications for parts with features that limit access, like slipper valves.
