Blade Holder/Bracket for Scraper and Plow Assemblies

Product Specifications

Technical details and manufacturing context for Blade Holder/Bracket

Definition

The blade holder or bracket is a critical mounting component within a scraper or plow assembly. It provides rigid support and precise positioning for the cutting or scraping blade, ensuring proper alignment and maintaining the blade's operational geometry during use. This component transfers operational forces from the blade to the main assembly structure, distributing cutting and scraping loads effectively. It also facilitates blade replacement or adjustment, allowing for efficient maintenance and reduced downtime.

Typical materials for this component include carbon steel and alloy steel, with a common material grade being QT450-10 ductile iron, which offers strength and wear resistance. Surface treatment often includes zinc plating with a thickness of 8–12 μm for corrosion protection, suitable for outdoor use. The mounting hole diameter ranges from 10.5 to 13.5 mm to fit standard blade bolts. The blade width compatibility is 100–200 mm, and the center distance between mounting holes ranges from 80 to 160 mm, determining the bolt pattern spacing.

The load capacity of the bracket is typically 5–15 kN, and it operates effectively in temperatures from -40°C to 85°C. Tensile strength ranges from 450 to 600 MPa, and hardness is 160–210 HB, balancing wear resistance and machinability. The weight is 1.5–3.5 kg, affecting handling and installation. Surface roughness is Ra 3.2–6.3 μm to ensure proper seating of the blade, and dimensional tolerance is ±0.5 mm to ensure interchangeability.

These specifications are reference ranges and must be verified for the specific model and application. Standards such as GB/T 1348, ASTM B633, ISO 1302, and ISO 2768-m are listed as procurement references. Always confirm model-specific values and standards with the legal manufacturer or supplier before purchase.

Working Principle

The holder/bracket mechanically clamps or fastens the blade in place using bolts, clamps, or other locking mechanisms. It acts as an interface between the blade and the main assembly frame, distributing cutting/scraping forces and maintaining the blade's operational geometry during use. The bracket ensures that the blade remains securely positioned under load, preventing movement that could affect performance or safety. It also allows for adjustment or replacement of the blade when necessary, simplifying maintenance procedures.
