Roller shearing blades

What do Roller Shearing Blades Mean?

Roller shearing blades, also known as rotary shear blades or disc shear blades, are circular cutting tools designed for use in roller shearing machines or slitting machines. These blades work by rotating against each other or against a fixed anvil to cut materials, typically sheet metal, coils, or strips, into narrower widths or specific shapes. The term “roller shearing blades” highlights their cylindrical or disc-like form and their application in rotary shearing processes.

Uses and Applications of Roller Shearing Blades

Roller shearing blades are widely used in various industries for continuous and efficient cutting of materials. Key applications include:

• Metalworking Industry: Slitting steel coils, aluminum coils, and other metal strips into desired widths for further processing. Edge trimming of metal sheets to ensure precise dimensions. Cutting blanks for stamping or forming operations.
• Steel Mills: Hot and cold shearing of steel bars, rods, and billets during the rolling process.
• Automotive Industry: Cutting sheet metal for car body panels and other components.
• Appliance Manufacturing: Cutting metal sheets for appliance casings and parts.
• Packaging Industry: Slitting and cutting various packaging materials, including metal foils, films, and laminates.
• Textile Industry: Slitting rolls of fabric and nonwovens into narrower widths.
• Paper Industry: Slitting large rolls of paper into smaller widths for printing and converting processes.
• Rubber and Plastics Industries: Cutting and slitting rubber sheets and plastic films.

Common Materials for Roller Shearing Blades

The materials used for roller shearing blades are selected for their durability, wear resistance, and ability to maintain a sharp cutting edge under continuous operation. Common materials include:

• Tool Steel (e.g., D2, A2, O1): Offers a good balance of hardness, toughness, and wear resistance, suitable for many metal slitting applications.
• 고속도강(HSS): Provides excellent wear resistance and the ability to retain hardness at elevated temperatures, making it suitable for higher-speed slitting operations. Grades like M2 are commonly used.
• Alloy Steel (e.g., H13, LD): Offers high temperature resistance and is suitable for hot rolling and hot shearing processes in steel mills.
• 텅스텐 카바이드: Provides exceptional hardness and wear resistance, ideal for high-speed slitting of hard and abrasive materials, significantly extending blade life. Can be used as solid carbide blades or as carbide inserts.
• Specialty Alloys: Depending on the specific application and material being cut, other specialty alloys may be used to provide optimal performance and longevity.

Heat treatment to achieve the desired hardness (typically in the range of HRC 57-62) is a critical step in the manufacturing process to ensure the blades can withstand the stresses of shearing. Coatings like titanium nitride (TiN) can also be applied to enhance surface hardness and reduce friction.

Common Roller Shearing Blade Shapes

Roller shearing blades are typically circular discs with various edge profiles depending on the cutting application:

• Solid Disc Blades: One-piece circular blades with a sharpened outer edge. The edge can be square, bevelled (single or double), or radiused.
• Inserted Blades: Feature replaceable cutting inserts made of a harder material (like carbide) attached to a steel body. This allows for cost-effective replacement of the wearing edge.
• Dished Blades: Circular blades with a concave or convex profile, often used for slitting where material tension needs to be controlled or to create specific edge profiles.
• Bevelled Edge Blades: The cutting edge is angled to create a shear point, which can reduce the cutting force required for certain materials. Single or compound bevels can be used.
• Scored/Crush Cut Blades: Used in pairs, these blades often have rounded or profiled edges that press against an anvil to create a score or crush cut, commonly used for thinner materials like paper or film.

The working principle of roller shearing blades involves the rotation of one or more circular blades against a stationary blade or anvil. The material passes between these rotating elements, and the shearing action occurs due to the applied pressure and the sharp edges of the rotating blades. In slitting operations, two or more roller shearing blades are often used in conjunction with spacers to achieve multiple cuts simultaneously, creating strips of the desired width. The precision of the blade geometry, the material of the blades, and the setup of the shearing machine are crucial for clean and accurate cuts.
