Edging Shears

Edging hydraulic shears for shaping the steel at the beginning of the punch. A steel edging enables the end of the punch to be joined to the cutting edge without welding. The standard machine has blades and a centring guide for steel heights 20 and 30, or 19-32. Special blades are also available for other heights. Equipped with stamping accessory for cutting to size from 0 to 100 mm. Double headed machines are also available on request, for the simultaneous application of different blade types with a saving of both money and space.

TECHNICAL DATA:

Cutting capacity max: 32x3 mm.
Electric motor:0,75kw.
Dimensions:L=450 P=450 Hz 1100 cm.

Vertical Hydraulic Puncher
 

Hydraulic machine for perforation of the die's internal plate with round or shaped punch in various forms. The matrix and the punch are regrindable and quickly replaceable and it is possible to position them to the machine axis at 0°, +45°, -45°, 90° at the operator's option. A rapid dechucking system with blank holder lifting combined to a micrometric adjustement of the matrix projecting part from the face, allows lo make perforations without distinction and very quickly, either on the plate already welded inside the die and on the single plate. The small size of the toolholder and of the blank holder allows to make perforations very close to the die's border, even on the already welded plate; The accuracy with which the machine is built allows to use very thin punches even on thicker plates (I.e. slot of 20x2 mm on plate 4 mm thick). The lever's manual control allows to lower and lift the punch at a speed and pressure that allow to approach the plate without making the perforation, once the positioning has been made the pedal control gives the high pressure required for the perforation. The adjustement through the ring nut and counter nut located on the upper part allows to adjust the punch run. The machine turning off is automatic and timed. A wide range of different shapes and dimensions of punches and matrixes is available, with possibility of custom-made supplies.

As the bars standard length is 1,5 m it is possible to put six containers for twelve steel rollers in total in different sizes (different Lengths on request) behind the cuffer. The blades can be replaced and resharpened easily and the cutting operation is controlled by the push button located on the head of the machine. The machine has been built following a modularity concept, so that you can equip it with attachments at any time in the future such as a feeding or a rectifying device should you need to cut to size single or mass-produced pieces, that can be set by means of the keyboard or other peripheral units (art. 10.400.000).

Cold Hydraulic Numbering Machine
 

The machine allows to directly cold-impress the steel cutting edge for symbolic numbering without having to heat the material. The machine hydraulic operation results in high operating frequency. The insert-shaped tools developed by STERN deform steel considerably avoiding both breakings and a lowering in the cutting edge. Thanks to both revolving insert carriers, four pairs of inserts can be used at a time. The carriers can rotate simultaneously by operating the handwheel on the front side. With the indexed handwheel on the rear side penetration depth of tools can be varied by centesimal increments as to adapt them to the various requirements and different kinds of steel. The inserts, available in various shapes, show a very close tolerance. The use of special high quality materials and a series of heat treatments developed by STERN assure them a long life.
