OBM-Series Hydraulic Presses

Description:

Pacific’s Straight Side Hydraulic Presses employ either a single or double cylinder six-point, non-metallic adjustable gibbing, with flange mounted piston and slide connections. All hydraulic presses are heavy plate steel and/or column construction, have large bed areas and generous open heights, and provide full tonnage throughout the stroke (up to 2000 tons), providing multiple job versatility and precision tool alignment.

Applicable markets:

All OEM and contract stamping markets performing draw press work, forming and/or blanking work on a single press

Key Features:

  • Straight Side hydraulic press affordability
  • Wide range of applications
  • Rigid, interlocked construction
  • Industry's most advanced and dependable hydraulic press system… designed and built by Pacific
  • Working speeds rivaling (sometimes exceeding) comparable mechanical designs
  • Total power / controllability throughout the stroke (compare to mechanical designs)
  • Six-way gibbing ensures smooth, non-binding, precision bolster movement … at an affordable price
  • Numerous optional features

OBM Series Pressformer Hydraulic Presses

Single Cylinder, Smaller Bed Version of Popular OBL Series

A True Pressroom Performer...Speed, Job Versatility, Proven ROI

Gib guided Hydraulic OBM Series Press from Pacific Press Technologies

Compared to its "bigger brother" Pacific Press Technologies' OBL-Series two point straight side press, the OBM Series consists of a single cylinder down-acting design; six-point, non-metallic adjustable gibbing; flange mounted piston/slide connection; heavy plate steel construction; generous bed sizes and open heights; and full tonnage supplied throughout the stroke-giving you job versatility and precision tool alignment. With the OBM-Series, you can perform draw work, embossing, coining, even blanking/punching work … all at an affordable price (OBM and OBL represent our economical alternative to straight side presses).

Choose from 100 to 1000 ton standard models, bolster sizes ranging from 3' x 3' (left to right x front to back) to 5' x 5' (see specification chart below).

Check out our other 6-way gib guided model, the OBL-Series for dual cylinder, larger bolster application. Or for higher precision 8-way gibbing models, take a look at our D-Series (dual cylinder) and M-Series (mono-cylinder) models.

OBM Series Pressformer Hydraulic Press Standard Features:

Consider these key machine features/user benefits…

  • Rugged Construction: Its interlocked frame design transfers press loads directly to parent metals (versus bolts or welds). Generous window openings in the side provide for easy access to the die area and permits continuous coil feeding operations. The 6-point square-type gibbing assures maximum bearing contact with long non-metallic gib surfaces-with tight gib clearance and accurate slide alignment helping to extend overall tool life and performance.
  • Safe and reliable press slide control is found in the Pacific-built modular 'stack' cartridge valve design.State-Of-The-Art Hydraulic System: Each press is equipped with a compact, high-speed hydraulic system enabling fast cycle speeds that can equal or surpass those of mechanical presses of comparable size. Safe and reliable press slide control is found in the Pacific-built modular "stack" cartridge valve design (quick response, minimized heat build up, reduced piping and fitting requirements, improvements in safety and maintenance requirements). The power unit provides three advance speeds (rapid advance, fast press, normal press) and two return speeds. Additionally, its large double acting cylinder provides support to cushion the break-though shock of heavy material punching with resulting improvements in punch and die life and work quality.
  • Superior Controllability: Gain increased levels of production, versatility and safety. Unlike mechanical presses, full rated tonnage and generous open heights deliver power throughout a long stroke. The OBM-Series offers a Pendant mounted, PLC Interface control (Allen Bradley 600 Panel View with color screen, Allen Bradley SLC 500
    Series PLC) to provide minimum set-up time and maximum flexibility. Tonnage is
    programmed directly through the control.
  • Laser Bend Alignment: Two laser line generators — one at each end of the tandem system - project a visible line at the centerline of the installed tooling. A blank with the bend lines marked is moved into the press brake until the mark and the visible laser line are aligned and the press brake is cycled to accurately complete the bend. An optional center mount (removable) laser line generator is available when a single press brake of the tandem system is to be used.

The OBM-Series offers a Pendant mounted, PLC Interface control.
