Upper Blade Holder for Stripping Blade Assembly

Product Specifications

Technical details and manufacturing context for Upper Blade Holder

Definition

The Upper Blade Holder is a critical component of the Stripping Blade Assembly, designed to rigidly mount and align the upper stripping blade. It ensures precise blade positioning relative to the material being processed, maintains consistent blade angle and pressure during operation, and provides structural stability to prevent blade deflection or vibration during high-speed stripping operations. The holder is typically mounted to the machine frame or actuator. It clamps or bolts the upper stripping blade in place, maintaining its fixed position. During the stripping cycle, it transfers operational forces from the machine to the blade while resisting reactive forces from the material, ensuring the blade performs its cutting or stripping function accurately and consistently. This component is manufactured from tool steel or hardened alloy steel, with a typical material grade of 45# carbon steel per GB/T 699, hardness of 38–42 HRC per GB/T 230.1, and a Ni-P surface treatment per GB/T 13913 for corrosion resistance. Key dimensional parameters include an overall length of 120–200 mm, width of 50–80 mm, height of 30–60 mm, mounting hole diameter of 10–16 mm (for M10–M16 bolts per GB/T 5277), and mounting hole spacing of 80–120 mm. Precision requirements include flatness ≤0.05 mm and parallelism ≤0.03 mm per GB/T 1184, and surface roughness Ra 0.8–1.6 μm per GB/T 1031. The operating temperature range is -20 to 80 °C, and weight ranges from 1.5 to 3.5 kg depending on size. These values are reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The holder is designed for use in machinery and equipment manufacturing, specifically within stripping blade assemblies. It is not a standalone product but a component that requires proper integration and verification. Always consult the manufacturer for detailed engineering drawings and installation instructions.

Working Principle

The holder is typically mounted to the machine frame or actuator. It clamps or bolts the upper stripping blade in place, maintaining its fixed position. During the stripping cycle, it transfers operational forces from the machine to the blade while resisting reactive forces from the material, ensuring the blade performs its cutting or stripping function accurately and consistently. The rigid mounting prevents blade deflection and vibration, which is critical for high-speed operations. The holder's flatness and parallelism ensure uniform force distribution across the blade, while surface roughness reduces friction and wear. The operating temperature range and material properties must be matched to the application to avoid premature failure.
