Special 4-cylindrical-column motorized hydraulic press to perform work involving deep-drawing MV-250 E model

The HIDROGARNE MV-250E model hydraulic press is designed with four cylindrical columns for increased accuracy and capacity, specifically recommended to perform work involving deep-drawing

As all our M series hydraulic press, this press is equipped with a mechanized lower and upper C45E stainless steel table with two DIN-650 grooves.

Structure and tables

  • This customized hydraulic press consists of three electro welded sections made solely of S355JR steel.
    • It’s stabilised and machined at the end of the structural welding process to ensure perfect parallelism and precision.
    • Calculated and designed by finite software.
    • With all this, we always guarantee our high precision and quality standards.
  • It’s equipped with a mechanized lower and upper C45E stainless steel table with two DIN-650 grooves.
  • We ensure a minimal friction in the vertical displacement of the upper table by installing alloy bronze bushings with graphite filler and a perfect parallelism by four cylindrical columns chromed, rectified and made of C45E steel.
  • The upper table ensures perfect alignment by means of four cylindrical lateral rails with anti-friction bimetallic caps which require no maintenance.
  • The lower table accommodates a hydraulic cushion of 50 tons with a useful area of 950 mm x 750 mm and three frontal arms to support the matrix on the outside of the press.
  • It has a NC SIEMENS KP-400 to control adjustments to the position of the upper table, changes of the speeds and cushion
  • It has a PLC SIEMENS S-7 that allows to program 99 memories.

Cylinder and hydraulic unit

  • The cylinder is single acting with a lapping liner, chrome plunger and maintenance-free anti wear guides.
  • The hydraulic group is located entirely on top of the hydraulic press.
  • The hydraulic group includes Denison silent hydraulic pump and air-oil cooler.
  • It includes:
    • decompression system,
    • pressure solenoid valves,
    • pre-filled valves,
    • switching valves,
    • check valves,
    • pressure relief valves and
    • anti-drop valves.

Electric installation and safety

  • The control panel features a switch enabling the user to select the desired type of work in a manual position to do adjustments and automatic for production.
  • Operation is carried out by low voltage electric pedals.
  • Safety is guaranteed by the use of level IV photoelectrical sensors situated at the front of the equipment, two fixed lateral protections panels and one practicable protection panel with a magnetic detector disconnection switch situated at the rear.
