PivaPunch with Cut-to-Width Station
The PivaPunch Punching and Cutting Center produces blanks and punched blanks which are cut both to length and to width straight from the coil. Parts are produced according to the job orders created by the ERP system.
The PivaPunch Punching and Cutting Center consists of the following main line components:
- Coil handling equipment comprising of a Coil stand, Two Coil cars or a Coil Storage System.
- Station for CNC punching of strip and for cutting to length of nests.
- Cut to Width station (CtW) where the blanks are separated from the nest.
- Pick and Place type Stacker customized to your needs.
- Software to read in the job list from the ERP, nesting of parts, part tooling, work list and reports back to ERP.
Punching the second nest and cutting to width of the first nest take place at the same time – in a single pass, straight from the coil.
In the punching station, two parts are punched at the same time using Thick Turret tools set in two Tool cassettes.
Dedicated press tools can be used for perforation, standard hole patterns, large holes and for forming.
The material utilization is the highest possible. No scrap between the parts in X-direction and parts are nested side by side in the optimum way.
Coils of standard width with raw edges from the steel mill are used. Part dimensions, both the length and the width - and the hole patterns are programmable. Also pre-cut blanks for turrets can be produced on Just In Time basis.
Quality of blanks
All four sides of blanks are cut in shears, each with one stroke, instead of having been nibbled resulting in good edge quality without tolerance peaks.
Sample case: HVAC, Wall Elements of Roof Top Units
Wall elements are produced in small series for units in delivery. The hole patterns are the same but the element sizes vary a lot, from some 200*300 mm to 700*2200 mm. However, the material and its thickness always remains the same.
Elements are nested side by side, punched & notched and cut-to-length and separated from each other in the Cut-to-Width Station with the CNC.
