BAR AND TUBE STRAIGHTENING PRESSES

Traveling Gantry Narrow Bed Straightening Press

Pressmach’s narrow bed Straightening Press is the perfect solution for straightening heavy shafts, tubes and bars. The workpiece is loaded onto pressing anvils. The gantry is then traversed over the shaft. Straightening accessories include: Power workpiece rotation, power lift, power anvil positioning, and power rotation stand positioning along the bed.

C-Frame-Straightening-Press

For straightening of small shafts, we offer C-frame Straightening Presses. A full range of straightening accessories is available for the series including: adjustable carriages, anvils, OD rotation fixtures, centering fixtures and indicators.

Fixed-Frame-Straightening-Press

For straightening larger shafts, Pressmach offers a special Straightening Press. Roller stands permit crane loading and workpiece positioning under a fixed ram.

The workpiece must be manually positioned under the ram, by moving it across the rollers. This provides an economical method of positioning heavy workpieces. Lift cylinders are available in the press bed to raise the workpiece for positioning of the press anvils.

Hybrid-Straightening-Press

For straightening larger shafts, Pressmach offers the Hybrid Straightening Press. Roller stands permit crane loading and workpiece positioning under a fixed ram.

The powered rollers allow the operator to position the workpiece under the ram, providing an efficient and economical method for positioning heavy workpieces. Lift cylinders are available in the press bed to raise the workpiece for positioning of the press anvils.

Horizontal-Bulldozer-Straightening-Press

Pressmach's horizontal presses are generally used for straightening or bending structural materials. Available in a variety of configurations. Options include conveyors, powered worklifters, powered work rotators, moveable anvil blocks, guided ram, t-slotted bolsters and pushbutton or lever controls.

PLATE AND WELDED WORKPIECES STRAIGHTENING PRESSES

​​​​​​​Traveling Gantry Wide Bed Press - O-Frame Press - Shipbuilding Hull forming press

Available in 100 ton to 10000 ton capacities, our Wide Bed O-Frame Straightening Presses with three axes of ram movement are specifically designed for straightening or bending large plates, castings, or weldments. The travel design of the gantry allows the workpiece to remain stationary while the pressing ram traverses to the high spot, eliminating frequent repositioning of large, heavy workpieces.

Additionally, hydraulic worklifts can be installed in the bed to assist in positioning the pressing blocks under the work. These worklifts free up overhead crane usage.
