HELLER HYDRAULIC SHEARS

 
Hydraulic Shear Features
 High Performance, High Value, Precise Control

Heller Hydraulic Shears are designed and constructed to provide high-speed shearing of blanks with clean, square edges, and to exacting working tolerances.

All Heller Hydraulic Plate Shears feature the swing beam design ensuring consistently accurate parts while providing smooth, quiet operation. These cost efficient, quality shears are available in capacities from 1/4" - 3/4" and 98" - 194" cutting length. Unitized box construction provides for maximum rigidity and strength.

This simple design with swing beam upper blade, strong rigid frames, and constant minimum rake angle assures that the sheared blanks are precisely cut within a minimum of bow twist or camber.

Heller Hydraulic Plate Shears are equipped with the productive features and safety devices for optimum, accurate shearing performance found on more expensive units. Feature for feature, Heller Hydraulic Shears are a smart, economical choice for plate shearing.

Mitsubishi Touch Screen PLC Control

The new 5.7 inch LCD touch screen controls settings for the blade gap adjustment, length of stroke, back gauge setting (inches or mm) and number of cuts. You only need to input the parameters you require. You can store up to 10 different job steps.

Blade Gap Adjustment

A conveniently located adjustment on the touch screen enables the operator to accurately adjust the blade clearance on both sides of the machine simultaneously.

Electronic Stroke Adjustment

For faster stroke rates, the operator can quickly adjust the stroke length to suit the job. Smaller blanks require less stroke length, thus providing faster cycling of the beam.

Front-Controlled Power Back Gauge

The standard heavy-duty, motorized back gauge is front operated and adjusted through the touch screen PLC. The precision back gauge is two position -- "down" for positioning and shearing and "up" for clearance. The gauge stop, automatic "retreat" position allows for shearing pieces longer than the extended range of the back gauge. The gauge reads in inches or millimeters.

Rear Guards and Work Piece Recovery

The rear of the shear is protected by a full width gate. There is a new work piece receiver with ball transfers installed that allows easy retrieval of the sheared piece.

Swing Beam Design

The beam holding the upper knife pivots on large spherical roller bearings, while hydraulic cylinders mounted into the side frames generate the cutting pressure. At the end of each cutting stroke, the hydraulic pressure is released and return cylinders move the beam to the top of stroke. The back gauge design and its interconnection with the swing beam gives immediate clearance to the sheared material, allowing it to drop away without jamming the lower blade and back gauge. Less maintenance is required with the swing beam design, since guides and slideways are eliminated.

Rugged Construction

Stressed-relieved, unitized box construction of the table and extra thick, rolled steel frames provide maximum resistance to deflection and torsional force. Increased throat depth in the side frames allows for progressive slitting of strips longer than the blades. Due to swing beam design, there is no deflection at the throat area of the shear.

Minimum Rake Angle

Due to strong, rigid construction, swing beam design, and powerful hydraulics, Heller Hydraulic Shears feature a constant minimum rake angle for consistent quality shearing, at full capacity, with the least amount of distortion.

Pressure Sensing Hold Downs

Hold downs are synchronized with the upper blade travel to provide maximum hold down pressure at the moment of shearing, thus, assuring cutting accuracy. As shearing forces on the plate increase, the hold down pressure increases to provide optimum gripping action. The hold down feet can hold two or more plates of different thicknesses for simultaneous shearing on the same stroke. At one end of the shear, two hold downs are mounted close together for ease in cutting narrow strips.

Squaring Arm

All shears are equipped with a heavy-duty squaring arm which is mounted at precisely 90 degrees to the shear blades. The squaring arm has a recessed stainless steel rule in inch/metric. The shear is also equipped with ball transfers to facilitate even the heaviest jobs.

Modern Block Hydraulics

The hydraulic system is comprised of long life, heavy-duty components mounted on a common block. Tubes and connections are minimized, and access and serviceability are made easy. The internal gear pump is quiet and extremely reliable, and is rated for years of trouble-free service. The large capacity oil reservoir eliminates the need for oil cooler. A factory preset relief valve prevents overloading mechanical parts and the hydraulic circuit.

Hinged Inter-Locked Barrier Guards

The Heller Shear has a unique inter-locked barrier guard. This allows the operator to safely pick up one side of the guard in order to work short pieces. Lifting the guard disconnects power to the foot pedal. The shear will not operate until the guard is lowered into the down position.

Shadow Lighting

For fast, visual positioning of sheets with scribed lines or punch marks, an intense light is provided. The light source casts a precise shadow line for accurate positioning and shearing.

Hydraulic Cylinders

The cylinders are mounted in cutouts within the extra thick side frames for easy accessibility. Separate, nitrogen-filled, return cylinders are mounted behind the hydraulic cylinders. The return cylinders, independent from the hydraulic cylinders, automatically retract the blade to the top of stroke position during power shut down, emergency, ot after the cutting stroke is completed. They also act as counterbalance to the shear.

Blade Clearance Adjustment

The clearance between the blades determines the quality of the cut edge and the thickness of metal that can be cut on a specific shear. Excessive clearance can produce a deformed, burred edge, while insufficient clearance usually results in a secondary shear or broken edge. Proper blade clearance normally produces clean, square edges on every part.

Quality Blades

Shears up to 1/4" capacity are equipped with high carbon, high chrome blades. All models, 3/8" capacity and above, are furnished with "shock resistant" steel blades.
