Description

Technical Field

[0001] This utility model relates to the field of band saw blade production equipment, specifically to a band saw blade cutting device. Background Technology

[0002] A band saw blade is a cutting tool widely used in woodworking, metalworking, and other material cutting applications. It consists of a continuous, thin steel strip with sharp teeth and is typically mounted on a band saw machine. Band saw blades are characterized by high cutting efficiency and a wide range of applications, capable of cutting workpieces of various shapes and sizes. During the production process, band saw blades require the design of appropriate tooth shape, tooth pitch, and tooth height based on the intended use and the material being cut. Then, using appropriate tooth-cutting equipment, the designed tooth shape is cut onto the steel strip. Strict control over the precision and consistency of the tooth shape is essential during the cutting process.

[0003] Chinese Patent No. CN220330137U discloses a band saw blade tooth pressing device, including an unwinding roller, a rewinding roller, and a worktable. A stamping assembly and a support frame are mounted on the worktable. The support frame is located on both sides of the stamping assembly and is detachably connected to the worktable. The support frame has a first groove for limiting the band saw blade. Two mounting plates are symmetrically mounted along the length of the worktable. A first conveying roller and a second conveying roller are connected to the mounting plates. A gap exists between the first and second conveying rollers, allowing the band saw blade to pass through. This invention has the advantages of keeping the band saw blade at the same height and improving the quality of band saw blade tooth pressing.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: only one band saw blade can be fed at a time, and only one band saw blade can be processed each time, resulting in low processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that only one band saw blade can be processed at a time, and to propose a band saw blade cutting device.
