Rotary Punch Punching
Patented Rotary Punch Continuous Sheet Punching Unit
With punch drums rotating at the same speed as the sheet, it punches coil sheet at 24 m/min without ever stopping it. Unlike eccentric presses, production is impact-free and burr-free.
Patented Rotary Punch Continuous Sheet Perforation Technology
Replacing conventional press lines, the Patented Rotary Punch Punching Unit punches coil sheet without ever stopping it, making cable tray production 4–6 times faster.
Rotary Punch Perforation Without Stop-and-Go
On conventional lines with an eccentric press of about 400 tonnes, the sheet has to stop at every punching step. In the Rotary Punch system the punch drums rotate at the same speed as the coil sheet and punch at a non-stop 24 m/min; 11,520 metres of sheet are processed in an 8-hour shift.
Eliminating the stop-and-go motion removes impact loads and cuts energy consumption to 0.16–0.25 kWh per metre (0.8–1.2 kWh/m on press lines).
Burr-Free Hole Geometry
The Rotary Punch punches make 7×18 mm oval (R3.5) holes at 50 mm horizontal and 25 mm vertical spacing in pre-galvanised and black St37 sheet from 0.7 mm to 2.0 mm.
Punches and dies are made of 1.2379 (D2) tool steel at 60 HRC; hole edges come out clean and burr-free.
22 kW AC Drive and Compact Frame
The unit is driven by a 22 kW AC motor and speed drive and needs no separate servo feeder. The line is controlled by a PLC and HMI.
The Rotary Punch, the straightener feeder and the guillotine shear sit on a common frame measuring about 2 × 2.5 × 1.5 m and weighing about 3.2 tonnes.
Technological Advantages & Innovation
