Hydraulic guillotine shears
sheet Metal

The hydraulic guillotine shears of the H5L range are driven by top-mounted cylinders. Our long experience in the production of Hydraulic Guillotine Shears guarantees a product of exceptional design and great efficiency. The fully open back provides the operator the possibility of easy removal or adapting different conveying and stacking systems to the machines. The all-welded interlocked construction makes the machine virtually indestructible. The HSL shears are delivered well-equipped and have as standard the SP9 Preselection-control. In option, they can be equipped with the 5C90 controller.

HYDRAULIC SYSTEM
The hydraulic system consists of a motor pump group and a multifunction manifold block for the control of the machine, easily accessible located at the front of the machine under the table. The connections to the cylinders, the hold downs, and pumps are by means of flexible hoses. Two high-pressure relief valves protect the hold downs and the cutting cycle from overload. Oversized oil tank for trouble-free high-production shearing. The parallelism control of the ram is based on the so-called differential principle. Guiding of the beam by roller bearings on hardened ways.

HYDRAULIC HOLD DOWNS
The hydraulic hold downs work independently, which makes it possible to clamp plates of different lengths and thicknesses correctly. The hold downs operate independently from the shearing pressure. On the left and the right-hand side of the machine, the hold downs are arranged more closely to allow cutting small plates without any problems.

CUTTING ANGLE ADJUSTMENT
Electro-hydraulic adjustment of the rake angle by push buttons at the control panel, and digital read-out (HSL-type). Automatic as a function of the plate thickness on the HSLX-type with SC90 control. This allows to cut thin material at a less angle, minimizing deformity of the sheared plate.

BLADE GAP ADJUSTMENT
The knife clearance is manually set by easily accessible levers (on each side) at the rear of the HSL machine. On the HSLX-models, this is automatically by two hydraulic cylinders, as a function of the entered sheet thickness.

STANDARD FEATURES OF HSL-RANGE
• Hydraulic motor-pump group arranged in front under the table of the machine, leaving the back-side completely free for easy removal or mounting conveying or stacking systems to the machine.
• 2 Upper-driven push-down cylinders.
• All operator controls are conveniently located at the left-hand side of the machine in the immediate reach of the operator.
• The standard SP9 control offers the following functions: automatic positioning of the back gauge to the preselected position with digital read-out, stroke control and selection for back gauge retraction.
• Electro-hydraulic rake angle adjustment by pushbuttons in the control panel.
• Quick manual blade gap setting by easily accessible levers at the rear of the machine.
• Tilting plate hold downs, pressure of which is independent from the shearing pressure, in order to clamp properly each sheet thickness. These hold downs are arranged more closely on the left and the right-hand side to conveniently cut small sheets.
• Hydraulic and electric overload protection.
• High shock-resistant premium quality blades with 4 cutting edges on all other models.
• Motorized back gauge, positioned by the SP9 preselection control. Digital read-out of the position.
• Shearing table with a number of square iron blocks, easing the sheet feed-in and increasing drastically operator's safety.
• Squaring arm of 1000mm with scale, T-slot and disappearing stop, attached to the left side of the machine.
• Movable foot pedal control.
• Instructions and maintenance manual.
• Non-filled oil tank (because of environmental regulations).
• Service tools.

SC90 CONTROL (OPTIONAL)
H5L EXECUTED WITH THE OPTIONAL 5C90 CONTROL IS CALLED HSLX.
Basic features of the SC90 control:
• Monochrome LCD screen.
• Memory capacity:
- max 200 programs with max. 400 steps.
- max 127 steps per program.
- material list of max. 32 materials.
• Each program contains the basic cutting parameters such as material type, material thickness, blade gap and cutting angle setting.
• Electro-hydraulic blade gap setting by 2 cylinders.
• Stroke control adjustment (cutting length).
• Automatic programmable retraction of the back gauge.
• Possibility of jog mode on back gauge.
• Backlash compensation, delayed sheet release.
• Mode selection Inch-Metric.
• (preset) Counter with 0-stop.
PROGRAMMING MODES:
Automatic:
By entering the sheet thickness for mild steel, the control automatically sets the blade gap and the cutting angle as a function of the sheet thickness. All parameters can be manually modified according to the actual data.
Manual:
All cutting parameters such as material type, sheet thickness, cutting angle and blade gap are programmed manually.

A specific feature of the H5L/HSLX range is the complete free rear space between the frames, so the machine can be executed with different sheet support, conveying, and stacking systems to improve production time.
HYDRAULIC SHEET SUPPORT SYSTEM which follows the movement of

 the beam. Principally for thinner sheets, it assures the perfect gauging while entering the sheet into the machine. During the cutting action, the sheet remains supported in order to avoid damage and deformation. When the cutting action is finished the plate slides down smoothly. The system can be switched off, e.g. for cutting thicker places.
Pneumatic sheet support system, scrap chute, and scrap container, counter rolls, alignment cylinders, and stacker with automatic adjustable arms.
The pneumatic sheet support arms hold the thin sheets for perfect gauging. A strip of scrap can be cut and removed when starting a series of cuts with a new sheet. The conveyor transports the plate to the stacker. A counter roll prevents scratching of the previously stacked sheets. The stacker arms lower automatically during stacking action.
