Piercing
PERF-ARC VERTICAL TUBE PIERCING UNITS
Use in punch presses, press brakes, air or hydraulic presses. Vogel Perf-Arc vertical piercing units offer a flexibility and adaptability which reduces both set up time and costs.
Perf-Arc units are designed for when unsupported piercing is acceptable. Unsupported piercing means the tube will deform or "dimple" around the pierced hole.
All Perf-Arc tools can be used singly or in multiples of two or more and can be positioned adjoining one another, spaced apart or at angles to pierce tubing which has been bent prior to piercing. All units are self stripping. Self contained units can be mounted directly to the bolster plate or sub-plates. Demountable units are split units which must be mounted both top and bottom preferably in a die set. Demountable units are also available keyed, top & bottom for direct mounting into most press brakes - pls. advise at time of order.
Note: When dimple-free piercing is required, a custom arbor piercing die, built in a die set, is required. This type of tool supports the ID of the tube during piercing, preventing deformation. These dies are built to suit the application. Please send us a print of your application details for quoting.
PERF-ARC DEMOUNTABLE UNITS
 |
All demountable units clamp the tube prior to the perforator entering the tube. Die set mounting top and bottom is recommended.
DIMPLED HOLE ONE SIDE ONLY NO HOLE OTHER SIDEPlease specify: tube and hole size required. Units may be ordered for round, square or rectangular tube sizes up to max. capacity of each unit.
Each unit includes a pair of clamps sized to your tube and one perforator of your specified size, each up to maximum shown below. |

DIMPLED HOLE BOTH SIDESPlease specify: tube and hole size required. Units may be ordered for round, square or rectangular tube sizes up to max. capacity of each unit.
One punch may be removed when only a dimpled hole one wall is required.
Each unit includes a pair of clamps sized to your tube and a pair of perforators of your specified size, each up to maximum shown below. |

PERF-ARC SELF CONTAINED UNITS
 |
Self contained units are the easiest to set up requiring only mounting of the base of the unit.
DIMPLED HOLE ONE SIDE CLEAN HOLE OTHER SIDEPlease specify: tube size, gauge and hole size required. Units may be ordered for round, square or rectangular tube sizes up to max. capacity of each unit. Exit hole (bottom wall) will be deformation-free however this hole will be up to 25% of the tube's wall thickness larger, due to slug clearance, (i.e. for 16 gauge, exit holes are up to .016" larger)
Each unit includes a perforator and a pair of clamps sized to your tube, up to maximums shown below..
The lower clamp includes an integral bushing sized both to your hole size and tubing gauge. |

These units are self-contained, mounting of the base is all that's required.
TYPES OF PIERCING
 How much dimple can I expect?
It's the question we get asked most. The amount of dimple these tools produce is based on many factors, including hole size in relation to tube ID, weld seam location, tube material and gauge, tooling sharpness, press speed, amount & type of lubrication used. For this reason, we cannot estimate the dimple you can expect. These tools are perfect when the exact amount of dimple is not critical and variation in dimple (i.e. as tooling dulls) will not impact part function, such as clearance holes, bolt holes,etc.
Will these tools pierce clean holes?
Clean hole piercing (no deformation to OD) can not be done with Perf-Arc tools. In order to prevent tube deformation, we will typically custom design and build a tool in a die set, with a mandrel to support the tube ID. Because of the custom nature of this type of equipment, please contact us and supply a print of your part so we can accurately quote an appropriate tool.
