Description

Technical Field

[0001] This utility model relates to the field of saw blade bending technology, specifically to a saw blade bending device. Background Technology

[0002] A saw blade is the core tool for cutting materials such as steel. It forms a kerf (cutting path) through the coordinated cutting action of its teeth. Each tooth contains three cutting edges (one end edge and two side edges) that work together to separate the material. The saw blade is the core component of a band saw, typically consisting of a strong, sharp-toothed blade tensioned within a frame. The material and design of the saw blade significantly influence its performance. Common saw blade materials include carbon steel and bimetallic saw blades. Carbon steel saw blades are suitable for woodworking and cutting low-hardness metals, while bimetallic saw blades combine low-alloy spring steel and high-speed tool steel, offering high hardness, high wear resistance, and high heat resistance, making them suitable for metal cutting.

[0003] In order to better adapt the band saw blade to the band saw, the band saw blade needs to be pre-bent during production. Existing saw blade bending equipment can only perform simple bending of the saw blade, which is difficult to meet the different bending requirements of the saw blade according to production needs, and its applicability is poor.
