HSL Shear

The hydraulic guillotine shears of the HSL 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 SP8 Preselection-control. In option, they can be equipped with the SC 70 controller.


Standard

  • 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 SP8 control offers the following functions : automatic positioning of the backgauge to the preselected position with digital read-out, stroke control and selection for backgauge retraction.
  • Electro-hydraulic rake angle adjustment by push-buttons in the control panel.
  • Quick manual blade gap setting by easy 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 holddowns are arranged more closely on the left and the right hand side to conveniently cut small sheets.

Options

SC70 control unit

shearh.jpg

HSL executed with the optional SC70 control is called HSLX.

Basic features of the SC70 control :

  • LCD screen with 16 lines of 26 characters.
  • 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.
  • Automatic programmable retraction of the back gauge.
  • Possibility of motorized adjustment of the back gauge position by 2 push-buttons.
  • Backlash compensation.
  • Mode selection Inch-Metric.

Programming modes :

  • Semi-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.

Squaring arms and front support arms.

Squaring arms and front support arms with or without scale, T-slots and flip-over stop. Lengths from 1.000 up to 3.000 mm.

Ball transfers in the iron table blocks.

Ball transfers mounted on the iron table blocks, for easy feed-in of the sheets.

Protractor for angle shearing.

Protactor for angle shearing

Knives for cutting inox.

Hand Safety Guard with hand gaps.

Different backgauge types.

The backgauge consists of 2 rigid arms (containing guidings and control spindle) and the parallel adjustable backgauge bar. This assembly assures a precise positionning of the sheet. Swing-up and swing-away types enable cutting of sheets longer than the standard stroke length. Motorised positioning with the SP8 preselection control or programmable positioning with the SC70 control. Digital read-out of the actual and preselected or programmed position: more info at key features

Pneumatic sheet hold-up system for cutting of thin materials.

Pneumatic sheet hold-up system for sheet thickness up to 4mm.

Different conveying and stacking systems with integrated sheet hold-up arms and scrap container.

Heavy Duty Conveyor and sheet hold-up system

Pneumatic sheet hold-up system, scrap chute and scrap container, counter rolls, alignment cylinders and stacker with automatic adjustable arms. The pneumatic sheet hold-up 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.

Safety fences and light beams at the backside of the machine (standard for countries requiring the CE safety specifications)


Features

Backgauges

The backgauge consists of 2 rigid arms (containing guidings and control spindle) and the parallel adjustable backgauge bar. This assembly assures a precise positioning of the sheet. Swing-up and swing-away types enable cutting of sheets longer than the standard stroke length. Motorised positioning with the SP8 preselection control or programmable positioning with the SC70 control. Digital read-out of the actual and preselected or programmed position.

Motorised Backgauge
  • Lateral movement front to back
  • Standard on 6, 8 and 10mm models
  • Power backgauge stroke 750mm
  • Expandable in option to 1000mm
Swing-up Backgauge
  • Power backgauge stroke 820mm
  • Available as option on 3m, 6 and 8mm models
  • When the backstop runs backwards, it will mechanically lift up to cut longer sheets
  • Also expandable to 1000mm stroke with lifting up feature
Swing-away Backgauge
  • Power backgauge stroke 1000mm.
  • Standard on all 13 and 16mm models
  • Available as option on 4m- 6 and 8mm and all 10mm models
  • When removing the axis in both carriers and run the backstop backwards, the complete carrier will swing away to the back, enabling to cut longer sheets

Hydraulics - angles settings

The hydraulic system consists of a motor pump group and a multifunction manifold block for the control of the machine, easy 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 base on the so-called differential principle. Guiding of the beam by roller bearings on hardened ways.

Hydraulic holddowns

The hydraulic hold-downs work independently, which makes it possible to clamp plates of different lengths and thickness 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 adjustments 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 SC70 control. This allows to cut thin material at a less angle, minimizing deformity of the sheared stock.

Blade gap adjustment

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

Sheet hold-up system

A specific feature of the HSL/HSLX range is the complete free rear space between the frames, so the machine can be executed with different sheet hold-up, conveying and stacking systems to improve production time.

Pneumatic sheet hold-up system for sheet thickness up to 4mm, assuring the perfect gauging while entering the sheet into the machine. During the cutting action and when not in use, the arms rest under a cover, thus avoiding damaging the arms itself when cutting heavier material.

Pneumatic sheet hold-up system, scrap chute and scrap container located before the conveyor, counter rolls, alignment cylinders and stacker with automatic adjustable arms. The pneumatic sheet hold-up 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.
