The Orbitform anti-rotate devices are mounted on multi-point forming heads and on some orbital heads when the specific orientation of forming is important to the assembly application or when it is important to prevent / reduce galling or rubbing between the peen tool and the rivet.

What is the Anti-Rotate Device?

The anti-rotate device is a tool mounted to the side of the orbital powerhead that maintains the orientation of the peen forming tool during the orbital riveting or orbital forming assembly operation.

Why is the Anti-Rotate Device important?

The anti-rotate device is important because there are various orbital forming and orbital riveting applications where it is necessary to maintain the orientation of the peen tool to the rivet (or post) being orbitally formed.

How does the Anti-Rotate Device help?

The anti-rotate device helps your product assembly process by ensuring the proper orientation between the orbital peen tool and the workpiece being formed.  The anti-rotate device also helps prevent or reduce galling or rubbing that can be caused by the peen tool interacting with a small diameter rivet.

Examples of Where an Anti-Rotate Device is used?

There are several examples of where an anti-rotate device is used during an orbital forming assembly process:

• When there is a need to maintain the orientation of the forming peen in relation to the rivet or post being formed.  An example of this is when there is a ledge that is higher than the final form height of the rivet.  The peen may need to have a flat shape machined into the side of the peen in order for the peen to have clearance to the side of the ledge.  The anti-rotate device is applied in this case to maintain the orientation of the flat sided peen so the flat side stays clear of the ledge.
• When riveting a product with a small diameter rivet, depending on the material of the rivet, it is possible that the peen tool could actually cause the rivet to rotate.  This rivet rotation can cause galling or rubbing to occur which can damage or disfigure the rivet.  The installation of an anti-rotate device helps to reduce or eliminate this galling effect and helps improve the product quality and assembly process.  The galling can be a negative cosmetic or negative functional aspect to be avoided.
• All Orbitform multi-point forming heads require the use of the anti-rotate device as part of the multi-point forming head design.

Clutch brakes are installed on Orbitform powerheads when there is a need to allow the motor to continue running while stopping the rotation of the spindle.

What is the Clutch Brake?

The clutch brake is an optional accessory sometimes incorporated with Orbitform powerheads to stop the spindle from rotating without shutting down the powerhead motor. The clutch brake is installed between the motor and the powerhead housing and can be used is most applications including when a gear reducer is required and/or when an offset motor mount is installed.

Why is the Clutch Brake important?

The clutch brake is important because sometimes it is necessary to stop the spindle from spinning without shutting down the powerhead motor. The clutch brake allows the machine's motor starter to operate longer since the motor starter will perform for a longer duration of time if there are fewer stops and starts of the motor.

What is Remote Stroke Adjust?

Remote stroke adjust is an optional powerhead modification that allows the powerhead stroke setting to be adjusted from a point away from the machine when the standard powerhead stroke adjustment knob is difficult to reach.

Why is Remote Stroke Adjust important?

It is necessary to adjust the stroke distance of the Orbitform powerheads from time to time during machine setup or when changing over from the assembly of one product to a different product. The remote stroke adjust is important in instances where the standard powerhead stroke adjustment knob is difficult to reach.

How does Remote Stroke Adjust help?
