Blade Holder/Assembly for Precision Shears

Product Specifications

Technical details and manufacturing context for Blade Holder/Assembly

Definition

The blade holder/assembly is a critical component of precision shear equipment that provides precise alignment, secure clamping, and stable support for the cutting blade. It ensures proper blade positioning relative to the material being cut and maintains consistent cutting performance throughout operation. The assembly is designed to accommodate blades within a width range of 100–300 mm and a thickness range of 10–25 mm, with a clamping force of 50–120 kN to ensure stability during cutting. Positioning accuracy is maintained at ±0.05 mm, which is critical for consistent cut quality. The operating pressure range is 1.0–1.6 MPa, and the operating temperature range is -10 to 60°C. The material grade is 42CrMo4 (DIN EN 10083), with a surface hardness of HRC 45–52 for wear resistance. The weight varies from 15 to 40 kg depending on size and configuration. The assembly is rated IP54–IP65 for protection against dust and water jets. Materials on file include tool steel, hardened steel, and precision-machined aluminum alloy. The working principle involves mechanical clamping mechanisms such as bolts, screws, or wedges to secure the blade, with alignment features like precision-machined surfaces, guide rails, or registration pins for accurate positioning. The assembly transfers cutting forces to the shear's main structure while allowing for blade replacement and adjustment. For selection, verify model-specific dimensions, clamping force, and compatibility with your shear system. Confirm standards and performance values with the legal manufacturer or supplier, as these are reference ranges. Maintenance signals include loosening of clamping elements, visible wear on alignment surfaces, or reduced cutting accuracy. Failure boundaries include excessive vibration, blade slippage, or misalignment beyond tolerance.

Working Principle

The blade holder assembly uses mechanical clamping mechanisms, such as bolts, screws, or wedges, to secure the blade in place. It may incorporate alignment features like precision-machined surfaces, guide rails, or registration pins to ensure accurate blade positioning. The assembly transfers cutting forces from the blade to the shear's main structure while allowing for blade replacement and adjustment.
