OHMA™ Air-Over-Oil Presses

The introduction of fastener welding & clinching marks a substantial advancement in CenterLine's already top-performing technology, aligning with the company's core mission of creating innovative solutions that empower customers to surpass their operational, customer, and profitability objectives while mitigating potential risks and stress.

OHMA™ SoftMount™ Clinch Press

Improve uptime for fastener installation in robotic automation cells.

The SoftMount™ Clinch Press is a robust solution for automated fastener installation, and capable of being integrated into CenterLine’s High Speed Fastener Solution™ (HSFS) robotic production cells.

This clinching solution uses compact, compliant tooling that allows the press to mechanically fine-adjust its position to a stamped hole. The tooling’s ability to float ensures that the press produces consistent and concentric clinch fastener installation.

Available in two configurations:

  • Inverted Feed Process (IFP) – For nut applications
  • Standard Feed Process (SFP) – For nut and stud applications

The SoftMount™ Clinch Press uses compact, compliant tooling that allows the press to mechanically fine adjust its position to a stamped hole. The tooling’s ability to float ensures that the press produces consistent and concentric fastener installation.

Advantages

  • Floating tooling adjusts itself to the hole in the stamping eliminating nuisance faults from the stamping getting hung up on the clinch pin.
  • No need to use 2/4-way locators to locate stampings.
  • Presses are configurable across a wide range of tonnage from 4-70 tons.
  • All presses are equipped with VeriFast™ IA Fastener Detection for quality monitoring (resolution 0.02 mm) and clinch set down.
  • Uses the industry standard OHMA™ cylinder with a soft-touch, non-shock approach to the workpiece and a 0.25-0.50” high force work stroke.
  • Advance and working strokes of the OHMA™ cylinder are adjustable with regulators.
  • IFP configuration utilizes CenterLine’s Lower Nut Feeder (LNF) unit to bury the fastener load time, decreasing cycle time.
  • The SFP configuration utilizes a spear feeder for fastener loading.
  • An LPT is used to measure actuator travel.
