OBM Series Hydraulic Presses

The Best of Both Worlds: Mechanical and Hydraulic Press Working Application Versatility

Compared to its "bigger brother" Pacific Press Technologies' OBL-Series two point straightside 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 straightside 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.

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.
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.
