  • Mainframe structure made in fabricated carbon steel and anchor bolted to the basement.
  • Chock stands for rolls, assembled on the mainframe structure.
  • Roll chocks fitted with precision bearings. The top chocks have vertical motion. it is equipped with balancing bar for parallelism and operated by pneumatic cylinders.
  • Carbon steel rolls of low inertia type, coated with Polyurethane of 90▒5 degree Shore. Also available are coatings with Hard Chrome and other hard metals with shot treatment at central area of rolls.
  • Bottom pinch roll equipped with back-up supporting flight rollers, preventing any bending of shaft of the roll (not applied on roll with soft covering).
  • C.A. drive motor equipped with vector frequency converter and fitted with precision transmission with "0" gap tolerance( without backlash).
  • Pulse generator and measuring wheel fitted on drive motor or on metal strip.

Main characteristics:

Rolls diameter mm 200
Rolls width mm Up to 2000

HIGH SPEED SHEAR

General Description:

The shear has a special design for Downside to Upside cutting motion. It is operated by electric motor with converter control system.

Note: Conventional Pneumatic Clutch system is not used any more in Electronic shears, because electronic system permits increase of processing speed without any maintenance troubles.

Mainframe base structure is of fabricated carbon steel and assembled on the base frame with the bridle rolls and it is equipped with:

  • Housing stands and blade support frame - carbon steel fabricated and stress relieved.
  • Bottom blade support frame is operated by motor and eccentric's shaft.
  • The top support frame comprises of a pair of precision mating wedges for GAP control, with visual index.
  • Set-in mechanism for cutting blade support located at the bottom side.
  • Four lines cutting blade design.
  • Bottom blade with butterfly cutting line shape ( X line shape ).
  • Eccentric shaft , driven by A.C motor with vector frequency converter.
  • Gearbox equipped with tempered and grinded gear and parallel shafts.
  • Centralised and automatic lubrication system for all components at working motion.

MAIN ADVANTAGES & DESAVANTAGES of Electronic Shear VERSUS Rotary Shear.

Item Advantages Disadvantages
1 Higher production rates for lengths lower than 600 mm. Slightly Lower production rates for lengths between 600 - 1200 mm.
2 Similar productions rates for lengths higher than 1200 mm. Similar productions rates for lengths higher than 1200 mm.
3 Higher accuracy & precision & quality on Diagonal dimension. Better square quality of finished products.
4 Half power consumption than Rotary Shear.
5 Lower noise level because clutch system is not required.
6 Cutting motion is from bottom to top side. No scratches on stacker.
7 Lower maintenance required.
8 Higher performance rate when "Heavy Duty Service" is required because mechanical concept of Electronic shear is better adapted for metal strip cutting motion than Rotary system.
9 Lower Price.
10 Metal strip must be stopped when cutting.
11 Strip loop is required in Rotary also to get similar square precision like Electronic Shear.
