Blade guide/alignment block Component – Rubber and Plastic Product Manufacturing

Component Specifications

Definition

A mechanical component in extrudate cutting systems that precisely guides and aligns cutting blades during operation, maintaining blade position relative to the extrudate flow to ensure uniform cutting dimensions and prevent blade deflection or misalignment.

Working Principle

Utilizes precisely machined surfaces and mounting interfaces to maintain fixed spatial relationships between cutting blades and extrudate material flow, often incorporating adjustment mechanisms for fine-tuning alignment to compensate for wear or production requirements.

Materials

High-strength tool steel (AISI D2 or equivalent), hardened to 58-62 HRC with corrosion-resistant surface treatment; alternative materials include tungsten carbide for high-wear applications or aluminum alloys for lightweight requirements.

Technical Parameters

weight 0.5-2.0 kg (depending on size)
