Crank shear

Crank Shears

Crank shear with two knife tracks. First track with one knife, second track with three knives per knife carrier.

Crank shear

The design of knife carrier will be adopted to the required application, e.g.:

crank-shear-grafik

  • One knife track, one knife: cropping, dividing (e.g. cooling bed lengths)
  • Low temperature rolling
  • One knife track, two knives: cropping, emergency cutting
  • One knife track, various knives: short emergency lengths
  • Two knife tracks, with additional switch:
    • 1st track one knife: cropping, dividing
    • 2nd track various knives: short emergency lengths

Shear start is initiated by pulse generator (billet head end). Cut according to chosen crop length. After cutting, the shear is stopped again. Crop end diverted into scrap disposal system
