Shear blade is a rotary cutting tool for metal sheets, it is for foot operated squaring shears and guillotine with 2 or 4 side shear cutting blade design. Besides, we have Flat bar shear, angle shear, bar cutter, coper notcher blades, or custom metal shear blades for hydraulic ironworkers. The Rotary shear blades are a cost effective foot shear to crop the material for mild steel and stainless steel.

What are the Shear blades working Principles?

The shear knives adopt highest quality tool steel that ensures reliability and durability. It includes a top moving blade and a lower blade. the upper blade on the tool holder is fixed to the lower blade seats and adopts reasonable blade clearance for various thicknesses. These sheet metal shear replacement blades are positioned at an angle relative to each other. These two blades are forced past each other with the space between them determined by a required offset. A 5-degree shear angle decreases the force by about 20%. and the shearing blade gap adjustment can influencees the quality of the cuts and tool life.

 

What is shear blade sharpening and material?

The hydraulic metal stomp shear blade sharpening is tough and durable. The shear knife blades are made of special steel alloy, with full heat treated through the toughest conditions. The shear blade material can be 9CrSi, or 6CrW2Si. Our blades are available in two-edge, and four cutting edges. We have manufactured blades for many shear brands: Accur, Amada , Yangli, Yawei, Trumpf, LVD. We offer complete designs for unique, obsolete, as well as custom design for homemade shears. we offer ironworker shear blades and replacement shear blades.

Shearing( die cutting) is a process that cuts stock without the formation of metal chips . If the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.

Hydraulic shearing machine is a kind of machine that uses the moving upper blade and fixed lower blade to apply shear force to metal plates of various thicknesses by using reasonable blade clearance, so as to break and separate the plates according to the required size.
