S-700 Automatic punching line for coil sheets

The extreme mechanical strength, combined with the possibility of performing drawing, stamping and marking of the pieces made, make the S-700 the ideal punching line for component manufacturers in the automotive and aeronautical fields. SMRE is able to configure the line according to specific requirements, thereby maximising the cost / productivity ratio.

Automatic stacking system

Punching unit

  • The punching unit can be configured according to the customer’s requirements.
  • Punches up to a maximum Ø of 114 mm can be installed.
  • A further unit consisting of a rotating punch makes nibbling and contouring possible.

Hydraulic press

  • One or several hydraulic presses with variable power from 20 to 90 tons each can be inserted inside the S-700 punching line.
  • Mold cutting or deformation processes can thus be carried out during the same machining process, before final cutting of the piece.
  • This avoids the need to transfer the punched sheets to a subsequent molding station, thus reducing production times and costs.
  • Positioning with decimal precision of the descent allows any type of processing even on variable sheet thicknesses.

Stacker

  • If the sheets leaving the punching line need to be stacked to be transferred to subsequent processing, our stacking systems provide the ideal solution.
  • The sheets are carefully positioned on both axes to also allow easy picking up by robots.
  • Depending on the requirements of the end user, various solutions for stacking or moving the sheets can be configured or designed ad hoc.

Coil

  • A sturdy motorised metal coil is configured according to customer requirements. From 2 to 8 tons of capacity, from 400 to 1600 mm in width.
  • Reading of the loop through ultrasound sensor and mass contact guarantee correct unwinding of the sheet metal and efficient feeding of the line, indispensable for precise performing of the work.
  • The possibility of installing a roll-holder cradle with hydraulic lifting ensures safe loading of the coil.
  • Alignment of the coil to the line is guaranteed by a hydraulic motor that allows easy movement.

Rectifier

  • The SMRE feeding rectifier guarantees precise positioning of the sheet through a dedicated anti-slip treatment of the feeding rollers.
  • The mechanical strength of the structure and of the yielding and straightening rollers guarantee unparalleled precision even on high strength, structural and high thickness materials.
  • The practical opening and feeding system allows easy and safe insertion of the sheet.
