HYDRAULIC OPEN FRONT PRESS TYPES PYEAND DOUBLE-SIDED PRESS TYPES PYZ

250 – 6,300 kN

Hydraulic presses from Raster-Zeulenroda innovative, reliable, powerful

The hydraulic open-fronted and double-sided presses can be used for all conven-tional forming processes as well as for straightening, embossing, calibration and bulk deformation. The optimized design of the frame provides high rigidity and ensures a long service life. The flexible adaptation of the machine to a wide range of work tasks expands the range of applications and guarantees

optimum ease of use. If these presses are expanded by a hydraulic deep-drawing device and a hydraulic ejector in the ram, they are converted into a triple-action deep-drawing press that delivers utmost efficiency. Integration into fully automated press lines is possible or feeding units can be adapted to operate with these presses.

TECHNICAL DATA AND SELECTION MATRIX

> Press frame a rigid welded steel construction

> T-slot design for the press table, ram and clamping plates according to DIN 650, two in each table and

ram (standard); arrangement: diago nal in PYE, parallel in PYZ

> Platen, anti-twist protected> Ram of box-type design, with 8-fold

sliding guides> PYE hydraulic unit in the frame mid-section, low noise

> PYZ hydraulic unit (pump, valve block, oil containers) in space-saving arrangement in or at the top part of the machine, low noise

> Oil filter with contamination indicator> Oil cooler (cooling by water)> PLC safety controller> 2-hand control panel, foot switch or joystick> Variable setting of the pressing

force

> Variable setting of the stroke length> Switching from rapid stroke to

working stroke is path-dependent> Switching of the ram movement is

path, pressure and pressure-time dependent

> Locking of the ram in the upper dead centre

(device obligatory under German accident prevention regulations for presses having stroke of > 500 mm or table depth of > 800 mm)

Options

> Further drill holes, breakthroughs and changes (table or platen) are possible

> Column guiding of the ram disk> Ram of box-type design, with 16.-fold roller guides> Oil cooling (cooling by air)> Hydraulic or mechanical ejector in

ram (see p. 9)

> Hydraulic drawing cushion with ejector function (see p. 9)

> Safety light curtain as intervention protection or integrated into the machine controller

> Variable ram locking in upper dead centre by hydraulically operated ram protection

> „Continuous stroke“ mode

> Vibration isolated installation> Cutting impact damping (separate

damping elements to compensate the cutting impact) or integrated into the cylinder

L F P

The simplest control type L is the installation of a cam track on the press frame. The setting of the upper stroke end position is performed with fully adjustable cams. The pressing force is adjusted manually at a pressure regulating valve and can be read on an additional pressure gauge.

Optional: Uncoded 4-line text display of– operating state– diagnostic system with fault messages– pressing force setting– press time setting– stroke counter programming

The press controls F and P enable the variable setting of every path parameter for the stroke position or the ram by implementing an absolute positioning measuring system (ultrasonic measuring system).

6,5’’ touch panel (optional 12“) for displaying and setting of– numbers and names of the current tool data record – memory for up to 100 data records– current operating mode– messages/fault diagnosis – current ram position– target and actual ram forces – speeds– stroke counter– top and bottom dead centres– transfer of path and pressure parameters from teach-in mode– different password levels can be selected

15’’ touch panel for displaying and setting of – numbers and names of the current tool data record – memory for up to 1,000 data records– current operating mode– messages (maintenance cycles)/fault diagnosis and on-line held functionality

(with Siemens fault description)– current ram position– target and actual ram forces (e.g., envelopes)– speeds– stroke counter– top and bottom dead centres– transfer of path and pressure parameters from teach-in mode– different password levels can be selected
