Shear Blade / Die: Component Specs, Materials & Applications

Component Specifications

Definition

A specialized industrial cutting component designed for torch or shear cutting machines, consisting of precisely engineered blades or dies that apply controlled mechanical force to sever metal materials along predetermined lines. These components maintain sharp cutting edges and dimensional stability to ensure clean, burr-free cuts with minimal material deformation.

Working Principle

Operates through controlled mechanical shearing action where two precisely aligned cutting edges (one stationary, one moving) apply concentrated force to exceed the material's shear strength, causing clean fracture along the cutting line with minimal plastic deformation.

Materials

High-carbon tool steel (D2, A2), tungsten carbide, or ceramic composites with hardness ratings of 58-65 HRC, often featuring wear-resistant coatings like TiN, TiCN, or diamond-like carbon (DLC).

Technical Parameters

Parameter	Typical range	Notes & selection driver
Hardness	58-65 HRC	For high-carbon tool steel (D2, A2) and tungsten carbide grades.ASTM E18
Thickness	10-50 mm	Blade thickness range for typical applications.
Tolerance	±0.01-±0.05 mm	Flatness and parallelism tolerance for cutting edge.ISO 2768-mK
Blade Length	500-6000 mm	Length range to accommodate various sheet widths.
Cutting Angle	2-10 degrees	Rake angle for optimal shearing; depends on material and thickness.
Max Cutting Force	50-500 t	Maximum force the blade can withstand without deformation.
Material thickness	0.5-25 mm for steel; up to 12 mm for stainless steel	Outside this window: Exceeding thickness causes blade chipping or breakage; below minimum causes poor cut quality.
Material tensile strength	Up to 1200 N/mm²	Outside this window: Higher strength leads to excessive wear and potential blade failure.
Operating temperature	0-60 °C	Outside this window: Above 60°C may soften blade material, reducing hardness; below 0°C increases brittleness.
Cutting speed	10-60 strokes/min	Outside this window: Higher speeds increase heat and wear; lower speeds reduce productivity.
Lubrication	Oil mist or flood coolant required	Outside this window: Insufficient lubrication leads to galling and premature wear.
