Scraper Blades: Pressure Range 10-50 N/cm, Thickness 3-12 mm

Component Specifications

Definition

Scraper blades are precision-engineered components installed on chip conveyors in machining centers and industrial equipment. They function as contact elements that physically scrape accumulated metal chips, swarf, and coolant residues from conveyor belts or chains, ensuring continuous material flow and preventing system jams. These blades maintain optimal conveyor performance by reducing friction, preventing material buildup, and extending equipment lifespan through controlled wear management.

Working Principle

Scraper blades operate through direct mechanical contact with moving conveyor surfaces. Mounted at strategic angles (typically 45-60 degrees), they apply consistent pressure to dislodge adhered materials. The scraping action creates a shearing force that separates chips from the surface while minimizing wear on both the blade and conveyor. Advanced designs incorporate spring-loaded or adjustable mechanisms to maintain optimal contact pressure as the blade wears down.

Frequently Asked Questions

How often should scraper blades be replaced?

Replacement intervals depend on material composition and operating conditions. Metal blades typically last 6-12 months in continuous operation, while polyurethane blades may require replacement every 3-6 months in abrasive environments.

Can scraper blades be sharpened or refurbished?

High-carbon steel blades can be sharpened 2-3 times before replacement. Tungsten carbide-tipped blades cannot be sharpened but offer 3-5x longer service life. Polymer blades are disposable and cannot be refurbished.
