Shear Blades Type And Construction

Shear blades are the key components of industrial shearing equipment. Their types and structures are diverse to meet different materials and shearing requirements. The following is a detailed description of the type and structure of the shear blades:

1、 Type

Straight scissors:

Features: suitable for straight-line cutting operation, which can ensure the flatness and accuracy of the cutting edge.

Application: commonly used for linear cutting of metal sheet, paper and other materials.

Curve scissors:

Features: with a curved blade, it can cut along the curve or complex shape.

Application: it is widely used in cutting operations in clothing, leather and other industries.

Blanking blade:

Features: designed for punching parts or holes of specific shapes, with high strength and hardness.

Application: it is commonly used in blanking operations in manufacturing fields such as auto parts and electronic products.

Metallurgical shear blades:

Features: mainly used for continuous casting, continuous rolling, slab uncoiling and other shearing operations in metallurgical industry.

Structure: rectangular, V-shaped, circular, arc-shaped blades are usually used to meet different cutting requirements.

2、 Structure

The structure of the shear blade usually includes a blade, a blade body and a connecting part.

Blade: it is the main working part of the blade. Its shape and material directly affect the cutting effect and blade life. The blade is usually made of high strength and high hardness materials, such as high-speed steel, cemented carbide, etc.

Cutter body: it is the supporting part of the blade, which is used to fix the blade and transmit the shear force. The cutter body is usually made of high-quality steel to ensure its sufficient strength and rigidity.

Connection part: it is used to fix the blade on the cutting device to ensure the stability and accuracy of the blade in the cutting process. The connecting parts are usually connected with bolts, nuts and other fasteners.
