AI Technical Summary

Technical Problem

Traditional saw chains have problems such as slow cutting speed, easy chipping, and excessive lateral torque when cutting wood, especially hardwood.

Method used

A saw chain with irregularly shaped cutting elements is designed, which adopts a multi-segment cutting surface structure, including cutting edge one, cutting edge two, side cutting edge and first and second entry points. By optimizing the entry sequence and angle of the cutting teeth structure, the cutting back is reduced and the cutting stability and reliability are improved.

Benefits of technology

It effectively reduces the risk of saw chain chipping, improves cutting efficiency and stability, and can still cut at high speed when encountering hard obstacles, avoiding the problem of not being able to cut due to chipping.

Abstract

A saw chain with irregularly shaped cutting elements, belonging to the field of saw chain technology, includes a saw chain body composed of connecting chain plates, drive chain plates, irregularly shaped cutting teeth, and rivets. The irregularly shaped cutting teeth include a connecting part located at the bottom and connected to the rivets, a limiting tooth located at the top front end of the connecting part, and a cutting tooth structure located at the top rear end of the connecting part. The top surface of the cutting tooth structure is formed by the connection of an inclined plane one and an inclined plane two. The intersection line between plane one and plane two forms the top surface cutting edge. The front end of the top surface cutting edge protrudes forward and forms a first entry point for cutting into the wood. Plane one is located on the side of the cutting tooth structure facing the drive chain plate, and plane two is located on the side away from the drive chain plate. This invention can effectively reduce cutting back, improve the reliability and stability when cutting wood, and reduce the risk of chipping of the cutting tooth structure.
