End of Arm Tooling for Press Tending


Your press tending and metal handling
robot is only as good as its EOAT.

With more than 15 years of experience in metal handling across a variety of industries, including deep experience within the automotive industry, SAS Automation understands your many complex design challenges. Heavy-duty materials, long reaches and multi-tasking are no match for purpose-built End-of Arm Tooling.

Robots have grown in popularity for metal handling applications because of their ability to manipulate, tilt or rotate metal blanks throughout the production process. Fixed with End-of-Arm Tooling, these robots can lift, position, and separate heavy, contoured, or oily blanks. Precise gripping components provide added designed flexibility to stack, crate pack or palletize finished parts. But that’s just scratching the surface: we've developed solutions from boom-type robotic applications where we can adjust the gripper on-the-fly to safety hold-down clamps for high speed applications.

Whether you need to unload a press, de-stack blanks, or perform a secondary operation such as bar code labeling or date stamping, End-of-Arm Tooling can Our EOATs can move your press stamping process toward safe, secure and repeatable blank transfers and placements.

“HX” End Effector Series for 5+ Axis Robots

Our Hybrid “HX” End Effectors for 5+ Axis Robots are made exclusively with the newly developed SAS HX hybrid frame profiles and modular off-the-shelf gripper components. This HX profile line is ideal for 5+ axis robots in multi-task, high-speed, heavy weight, or press tending applications.

This new HX End Effector is specifically designed for increased flexibility, offering an optimal “hybrid” design that includes the benefits of tubular frame adjustability as well as extruded channel frame profile rigidity. Robotic production use includes long reach boom press tending applications, heavy-duty material handling, or multi-task applications.

Key features and benefits:

  • Direct side channel mounting of standard SAS gripper component hardware, eliminating rotation or twist problems.
  • Modular design allowing for side mounting or circumference component or connector clamping, offering added compatibility to other brands and types of systems.
  • Available with compliant oil-resistant vacuum cups as well as safety hold down clamps to secure parts even when system fails
  • Available in sizes of 40mm and 60mm OD, (HX-40/HX-60).
  • Center hole can be tapped to accommodate an M8 sized screw for connection of end plates/caps and connectors

Damage-Preventing Sensors

In addition to providing a safer and faster production operation, robotic End-of-Arm Tools also have the ability to prevent die and press damage when feeding pre-cut or stamped blanks into a forming die. Serious die and press damage may occur when double blanks are formed or stamped. It is critical to separate sticky or oily blanks and verify that the tool picks only a single piece. Adding a DSD-36 Double Sheet Detector is the simplest method to reduce die and press damage when picking pre-cut or stamped blanks from a pin pallet or feed conveyor.

The sensor is located on the EOAT used to feed blanks into a forming die. If stacked on a pin pallet, the blanks must be separated with a blank fanner magnet. Prior to use on a new blank, the sensor is calibrated to that specific gauge thickness. The sensors’ range of detection is 0.25 - 2.3 mm in thickness. As the robot picks the top blank from a stack, and before it is placed in the die, the sensor uses electromagnetic pulses to quickly measure the thickness of the blank – ensuring that the EOAT has picked only one. If a multiple-blank pick is sensed, the robot will place those blanks on a scrap pallet and restart the blank loading process.

Ensuring that double blank picks are not made will help prevent possible die and press damage. Broken guide blocks, sheared hardware, and fracturing of the die are often the results of a double blank pick. With proper setup, die and press damage from this type of error can be significantly reduced or altogether eliminated.

While the SAS Automation Double Sheet Detector is normally mounted on the End-of-Arm Tool, the unit can also be used with automatic sheet and blank feeders. The detector includes a control module inside a metal housing and a mounted probe to verify the thickness of ferrous metals with electromagnetic pulses.
