The Omera Oil-Hydraulic Press with Two Uprights, model OPI.M - 315, is a double-effect machine designed for blanking, coining, and drawing steel plates. It features a monolithic structure made of welded sheet metal, heat-treated and sand-blasted to eliminate residual internal stress and ensure maximum rigidity. The slide, also made of heat-treated welded steel plate, is guided by eight self-lubricating sliding blocks with a play take-up device. The lower surface of the slide has T-shaped milled grooves for accommodating dies. The table is constructed from extra-thick steel to prevent bending and includes T-shaped milled grooves and holes for blank-holder pressure pins. The main cylinder is made of single-piece cast steel, internally ground and lapped, while the piston is made of ground and tempered steel, guided by special bronze bushes and sealed with gaskets.

Usage Features:

The press is controlled by a hanging push-button board and a control console. The main control pulpit must be positioned at the front of the press for manual loading and unloading.

Electronic Cycle Cams: A programmable electronic system, using two wire encoders, controls slide and blank-holder positions and solenoid valve sequences. Parameters like Top Dead Center (T.D.C.), Braking point, Bottom Dead Center (B.D.C.), and Knockout intervention point are programmable via an Industrial PC.
Blank Holder Cushion: Oil-hydraulic, with a steel cylinder under the table, adjustable force, and sliding on ground and hardened steel columns. Its position and counter force during drawing are set via the Industrial PC.
Functioning Modes:
- Adjustment Cycle: For die replacement and setting, allowing slow slide and blank-holder movement.
- Single Cycle Without Blank Holder: Fast downstroke, braking, drawing, movement inversion, and slide upstroke to T.D.C.
- Single Cycle with Independent Blank Holder: Similar to single cycle, with blank holder rising independently at T.D.C.
- Single Cycle with Direct Blank Holder: Similar to single cycle, with blank holder rising with the slide.
Die Loading/Unloading: Involves selecting the adjustment cycle, locking/stopping the slide at T.D.C., positioning the blank holder, cleaning surfaces, and securing the die.
Automatic Feeder Operation: The press is pre-arranged for interfacing with standard sheet metal feeders. Safety barriers must be adapted, and specific checks performed before operation.
Slide Holding Device: An automatic oil-hydraulic device physically blocks the slide's downstroke when the machine is inactive. A limit switch deactivates downstroke control if the slide is locked at T.D.C.
Knockout: An oil-hydraulic cylinder inside the slide piston ensures automatic removal of drawn pieces during slide upstroke. It can also function as a "THIRD EFFECT" cushion during downstroke.

Maintenance Features:

Oil Leaks: Inspect and tighten pipe fittings every 300-400 working hours. Low oil level is signaled by the Industrial PC.
Oil Filter: The Industrial PC signals clogging. The filter cartridge (MPS 350 R G1 P10 A FX, Omera code 76801060) and cartridge (CS 150 - P10A, Omera Code 76801120) should be replaced as soon as possible.
Tank Air Filter: Clean or replace the cartridge (SA 185 G1 L10 A, Omera Code 76807017; cartridge A 10 L10, Omera Code 76807038) every 500 working hours, or sooner in dusty environments.
Oil Change: Change oil (ESSO NUTO H 46 or equivalent) every 2000 working hours.
P.L.C. Central Unit: The "memory card" can be replaced by following a specific procedure involving CPU key manipulation and program loading via the Industrial PC.
Main Cylinder & Blank Holder Cushion Cylinder: Omera S.r.l. supplies complete replacement gasket sets, not individual gaskets.
Slide Play Take-up: The self-lubricating sliding shoes allow play adjustment in lengthways (face A) and crossways (face B) directions by loosening/tightening screws and inserting/removing shims.
Lubrication System: Regularly check grease level in the tank (ESSO BEACON - EP1, 2 Kg) and refill when run out, using the provided filter.
Encoder: Position transducers for slide and blank-holder stroke. Safety limit switches (TELEMECANIQUE ZCK-J1 + ZCK-E67) prevent overstroke and should be checked for correct function during maintenance.
Maintenance Schedule: The Industrial PC displays recommended maintenance intervals. A summary table outlines interventions like oil replacement, checking leaks, filter replacement, heat exchanger efficiency, grease level, gib tolerance, seals, and safety devices.
Long Periods of Inactivity: Run the machine for about 1 hour every two months.
