Product Description

HSS Toothed Knife for Tire Shaving

Key precision tools for tire production and retreading include: - Tire Trimming Knife - Pin Vent Trimmer Blades - Toothed Knives for Tire Shaving - Serrated rubber cutting knives (toothed rubber cutting knives) - Industrial shaving knives for tire industry- Tire surface preparation bladesThese tools remove extra rubber burrs after tire molding and vulcanization. They are needed to ensure good tire appearance and quality.

Main Functions & Application Scenarios

Tire molds have small vent holes to let air out during molding and vulcanization. After vulcanization, rubber burrs form on tire sidewalls and shoulders. These burrs hurt tire appearance and performance.

Functions of Toothed Knives

With sharp, precise edges, they: - Remove leftover rubber from tires quickly and cleanly - Leave a smooth surface - Meet factory and retreading quality standards

Application Scenarios

New Tire Manufacturing: Used with robots or trimming machines on production lines for fast, batch trimming.
Tire Retreading: Use Tire retreading tools (toothed knives) to trim edges and seams after retreading, ensuring the quality of retreaded tires.

Blade Types & Materials

Blade shape and material match different equipment and processes. Choose based on rubber’s elasticity and abrasiveness. Core needs: - High wear resistance - High sharpness - Long service life

Common Blade Types

Circular Blades: Most common type in the industry. Small diameter, fits rotary trimmers. Enables continuous, fast cutting for large burr areas.
Custom tooth profile blades (V-shaped/Irregular): Custom edges for trimming special patterns, corners, and irregular tire areas.
Straight Blades: Straight edge for precise linear trimming of tire edges and seams.

Blade Material Options

Tungsten Carbide / Hard Alloy

- Very hard and wear-resistant - Lasts much longer than steel blades - Stays sharp longer, reducing machine downtime - Good for large-scale automated production

High-Speed Steel (HSS)

- Cheap and easy to process - Good for small to medium batches, non-continuous trimming - Needs regular sharpening to stay effective

Production & Maintenance Tips

Blade quality and daily care affect: - Trimming speed - Blade life - Finished tire quality Regular maintenance is a must.

Dimensional Accuracy

Blade inner diameter, outer diameter, and thickness must match trimming equipment exactly. Gaps will reduce cutting precision.

Edge Quality

Use mirror-polished edges to: - Reduce rubber residue - Lower cutting resistance - Ensure smooth, burr-free trimming

Daily Maintenance

- Clean rubber residue from blades after use - Regularly apply special lubricant - Reduce friction and prevent rubber from sticking

How Toothed Design Works (Serrated Rubber Cutting Knives)

Flat-edged knives get hot when trimming thick rubber. Serrated rubber cutting knives have alternating cutting points that reduce friction. This helps:

Reduce heat: Prevents rubber from burning.
Improve grip: Teeth hold rubber better to avoid slipping.
