SEW  HIGH SPEED PRECISION POWER PRESSES

 

Salient Features

 High Performance, High Production, Reliability, Economy & Safety Ensured By :
- Welded Steel construction with maximum rigidity & lowest deflection
- Fabricated steel slide running in extra long guides to ensure perfect alignment.
- Combination clutch and brake with inter-locking of functions and dual sloenoid valve to ensure "FAIL-SAFE" operations.
- Variable speed drive for wider angle and quick selections of speed
- Motorised lubrictaion system, centrally controlled and monitored so that in case of any fault in the system the machine stops         
  immediately.
- Well-designed control station for easy operations.
- Stroke counter slide adjustment indicator provided on machine
- Hydaullic overload safety (optional)
- Flywheel and motor guards
- Bearing temperature sensor is an optional feature this prevents damage to major bearings by stopping the machine if bearing temperature exceeds preset values.
FRAME : Has been specially designed welded joints with high damping characteristics. The frame structure is built with large sections & wide columns to achieve both vertical & lateral rigidity to give longer, productive machine life.
GUIDING ARRANGEMENT : The extra-long eight point guiding system fully supports the slide through its entire stroke. The guiding system permits the precise adjustment of slide running clearances and also helps achieve parallelism and squareness of travel, thus improving tool life.
SLIDE : The Box-type construction of the slide is designed for maximum rigidity. The pitman connecting links using ball joints are designed for minimum weight, also giving slide adjustment setting accuracy upto 0,025 mm. This helps faster machine set up & improved tool safety during set up.
PNEUMATIC COUNTER BALANCE : Pneumatic counter balance cylinders eliminate the clearances in all the bearings & connections in the load path, helping to precisely determine the penetration of punches in the die for convenient dies set up and improved tool life.
PNEUMATIC CLUTCH : The fail-safe, pneumatically operated clutch brake combination is designed to provide excellent slide motion control even at high speeds. Adequate energy required for blanking operation is ensured by optimised design of the flywheel.
MOTOR DRIVE : Variable speed drive is designed for the power requirements of the machine over the complete speed range.
ELECTRICAL CONTROL : The control system incorporates the essential safety requirements and includes features like speed indicators, stroke counter, status indicator and two hand engagement device. Parallel operation control station on the machine facilitates tool setting, continuous operation and TDC stop.
