PMM HY - Pressa Ibrida Oleodinamica Elettrica - Sicmi

PMM HY – Electric Hydraulic Hybrid Press with Mobile Stanchion

  • Electric and Hydraulic Hybrid Press specifically designed for straightening operations and high precision sheet metal straining with significant energy saving.
  • Electric displacement to obtain millimetre precision in sheet metal without moving the work table.
  • The hydraulic main cylinder features an inbuilt power accumulator to reduce to a minimum the consumption of hydraulic oil.
  • Laser reading of the sheet metal detects the deformation spots. In automatic mode cycle the press positions on the spot to process.
  • Set up for INDUSTRY 4.0: can be connected to the office server via LAN network to access input and output data.
  • Wireless radio control designed for safe and millimeter precise use.

DESCRIPTION

Electro Hydrostatic Unit

The PMM-HY model innovation: the operating system of the main cylinder using a Motor-Electro hydrostatic Pump Unit (EPU). This innovative system provides these advantages:

  • High precision of movements, with high flexibility and dynamic configurations to ensure maximum adaptability to the type of work to perform.
  • High energy efficiency as it activated only at the time of use by the operator.
  • No hydraulic control units and complex piping needed, thus overall dimensions are reduced.
  • Compact design with special interface that allows direct connection to the cylinders reducing additional spaces.
  • Reduced environmental and noise impact.

Press Body

  • Arc-welded very rigid steel structure includes the upright and the work table.
  • Solid unit arc-welded upright slides on the work table runners. The main cylinder is housed on the upright sliding right and left on steel wheels.
  • The structure is engineered to have maximum stiffness and minimum flexure in condition of maximum load. This ensures perfect processing operability.

Oleodynamic System

  • Placed on the upper part of the stanchion using two-stage pumps and the electric motor, this is the best solution for dimensions, performance and noise.
  • The accumulator reduces the amount of oil used on the press.
  • The cylinder has 3 down stroke speeds can be programmed and operated according to need.
  • Brushless motor and the servo valve unit allow reduced consumption and the use of only the oil internal to the cylinder.

Electric System

  • The press is provided with Touch-screen command control and push buttons to set the work parameters and to view the positions.
  • Complete and safe control of the press function and its cycles.
  • The screen displays the data of the readings taken by the laser to allow the operator to intervene either in manual or automated mode whenever necessary.
  • The press is provided with radio control to carry out processing in autonomy.

Oleodynamic Cylinder and Auxiliary Electric Cylinders

  • Specifically engineered to meet the required use of the press.
  • In addition to special care of the inner surface and the rod, the hydraulic cylinder is also provided with high quality seals to optimize sealing and friction.
  • The electric cylinders allow pin point accuracy of movements.

Preset for Industry 4.0

The setup includes:

  • Communication board to connect to the company network (data read/write on 2 data blocks on the PLC).
  • The alarms shared are: Alarms, Counter, Pressure, Setup of recipe in Use and Pieces produced. For the PLC: Recipe selection and Counter reset.
  • Block mapping and data format custom-defined during design phase.
  • Prearranged for Remote Assistance: presence of a Switch to enable and disable a VPN protected line to allow connection of remote assistance to the PLC in case of need.
