Shear Technology

Pressmach Press Equipment offers a number of shear equipment options that provide cost-effective solutions for cutting continuous coil into blanks in order to optimize production efficiency and material utilization.

These solutions are incorporated into Cut-to-Length and Blanking Lines as well as our Transfer Press Feed Lines to provide efficient and flexible coil processing systems.

 

SHEARS USED IN A CUT TO LENGTH LINE

START-STOP SHEAR

Pressmachs’s start-stop shear cut to length line is mainly classified into three types:
      1) Crankshaft shear CUT TO LENGTH LINE 
      2) Hydraulic shear CUT TO LENGTH LINE
      3) Trapezoidal shear (swing shear) CUT TO LENGTH LINE

  • Crankshaft shear CUT TO LENGTH LINE: It is recommend for light and medium gauge material with the max 6mm thickness. The line is commonly composed of decoiler, corrective leveler (4 high/5high/6high), looping pit table, servo roller feeder, shear, conveyor, stacker.
  • Hydraulic shear CUT TO LENGTH LINE:  It is recommend for medium and heavy gauge material with the max 25mm thickness. The line is commonly composed of decoiler, coil unwinding system, straightener, trimmer, corrective leveller, hydraulic shear, conveyor, stacker.

ROTARY SHEAR CUT TO LENGTH LINE

Pressmach cut to length line with rotary shear is mainly used for cutting light gauge and medium gauge material. For steel the thickness is up to 3.0mm; for aluminium up to 6.0mm. Suitable for processing cold rolled steel, stainless steel, aluminium and etc. Applicable for service centres, steel mill and finished product industries.

Pressmach rotary shear CTL is composed of decoiler, peeler, leveller, length measuring unit, rotary shear, double station stacker. The max line speed is up 100m/min, cutting rate up to 200cuts/min, length tolerance up to ±0.2 mm/m.

FLYING SHEAR CUT TO LENGTH LINE

The purpose that Pressmach developed this type of flying shear line is to achieve better flatness accuracy and a continuous production, and reduced required space.

Pressmach’s flying shear cut to length line can be applied for processing material like HR (hot-rolled steel), high tensile steel, pre-painted steel, stainless steel, aluminium and etc. The thickness range covers from 0.1 to 25mm. Line speed is 50m/min max.

Commonly the flying shear cross cutting line is composed of decoiler, pinch roll & straightening unit, leveling unit, length measuring unit, flying shear, stacking unit(additional equipment like side trimmer, PVC film applicator, Crop shear…can be incorporated).

Trapezoidal shear (swing shear) CUT TO LENGTH LINE

Automotive application: Trapezium form cutting line

END SHEARS

End shears allow the cutting of the head and the tail of the coil and for fractionating the coil for advanced machining.
End shears can be of two types – end shears cutting from above and end shears cutting from below.

FLYING SHEARS, ROTARY SHEARS

Flying shears are used to cut the coils to size. The machines are designed to meet requirements related to the type of material and the corresponding size, thickness and strength. Our shears represent the accumulation of the ultimate technology, designed to achieve high performance as well as to guarantee the maximum precision in cutting to length.

TRAPEZOIDAL CUTTING SHEARS

Installed into blanking Cut-To-Length lines, the machinery is primarily designed for cutting trapezoidal carbon steel sheets used in the automotive industry.

CORRECTIVE SHEARS

Shears designed for correcting “out of line” situations in the presence of bowing cut coils.
