Toothed Knife for Tire Shaving:

Tire Trimming Knife,Pin Vent Trimmer Blades and Toothed Knives for Tire Shaving are core precision tools in tire manufacturing and retreading. They are specifically designed to remove excess rubber burrs remaining after tire molding and vulcanization, and are essential for ensuring the appearance and quality of tires.

Main Functions and Application Scenarios of Toothed Knife for Tire Shaving

During tire molding and vulcanization, the mold has fine vent holes to expel internal air. After vulcanization, rubber burrs/flashes form on the sidewalls and shoulders due to these vent holes, affecting the tire's appearance and performance.

Functions of Toothed Knife

Using high-precision sharp edges, they accurately, quickly, and cleanly remove residual rubber from the tire surface, resulting in a smooth and clean surface that meets factory and retreading quality standards.

Application Scenarios

New Tire Manufacturing: Used with robotic arms/dedicated trimming machines on automated production lines for high-speed, online batch trimming;

Tire Retreading/Remanufacturing: After retreading the tread of used tires, fine trimming is performed on the edges and seams to ensure the quality of the retreaded tires;

Blade Types and Materials

The shape and material of the blades are adapted to different trimming equipment and process requirements. Selection should consider the high elasticity and abrasive nature of rubber, with the core requirements being high wear resistance, high sharpness, and long service life.

Common Types of tire toothed knife

Circular Blades: The mainstream type in the industry, with a small diameter design, suitable for rotary trimming machines, supporting continuous, high-speed cutting, and suitable for trimming large areas of rubber burrs;

V-shaped/Irregular Blades: Customized edge design for precise trimming of special patterns, corners, and other irregular areas of the tire;

Straight Blades: Straight cutting edge, suitable for linear precision trimming of tire edges and seams.

Material Selection for Tire toothed Knife

Tungsten Carbide / Hard Alloy:

Possesses ultra-high hardness and wear resistance, offering a service life far exceeding steel blades. It maintains sharpness for extended periods, reducing equipment downtime for blade changes and is suitable for large-scale automated production.

High-Speed Steel (HSS):

Economical and easy to process, suitable for small to medium-batch, non-continuous trimming operations. Requires regular sharpening to maintain cutting performance.

Production Process and Maintenance Key Points

Blade quality and daily maintenance directly affect trimming efficiency, blade lifespan, and the quality of the finished tires. Regular maintenance is essential.

Dimensional Accuracy:

The inner diameter, outer diameter, and thickness of the blade must precisely match the corresponding trimming equipment to avoid installation gaps affecting cutting accuracy;

Edge Quality:

Opt for mirror-polished edges to reduce rubber residue, lower cutting resistance, and ensure smooth, burr-free trimming;

Daily Maintenance, Cleaning, and Lubrication:

Promptly remove rubber residue from the blade surface after operation, and regularly apply a special lubricant to reduce friction and prevent rubber adhesion;
