Description

Technical Field

[0001] This application relates to the technical field of bar cutting, and particularly relates to a metal band saw for bar cutting. Background Art

[0002] Band saws mainly use saw bands or saw blades as cutting tools to saw various metal materials such as alloy structural steel, medium carbon steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, bearing steel, acid-resistant steel, and straightened steel. Band saws have the characteristics of fast cutting speed, high dimensional accuracy, and small material loss, and are mostly used in the preparation workshop to cut various profiles such as bars and pipes.

[0003] After checking the publication number: CN219786784U, a metal band saw is disclosed. In this technology, it is disclosed that "including a machine body and a cutting mechanism, a carrier plate is installed on one side of the cutting mechanism, and the carrier plate is rotatably connected to the upper surface of the machine body. Vertical plates are symmetrically welded on the upper surface of the carrier plate. A first screw rod is screwed on the surface of the vertical plate and penetrates through the vertical plate. A clamping plate is installed at one end of the first screw rod. A U-shaped frame is welded on one side of the vertical plate. A second screw rod is screwed on the top of the U-shaped frame and penetrates through the top of the U-shaped frame. A pressing plate is installed at the bottom end of the second screw rod. Angle scales are arranged around the outside of the carrier plate, and the angle scales are engraved on the upper surface of the machine body. Identification lines are engraved at the edge of the upper surface of the carrier plate. A positioning bolt is installed between the vertical plate and the U-shaped frame, etc. technical solutions. It can achieve the technical effects of cutting the bar at any angle to meet the needs of material processing, etc."

[0004] Regarding the above related technologies, the inventor believes that first, the serrated knives in the existing bar cutting saw beds generally cut the bar directly vertically downward. This cutting method is not fast enough and does not have a reciprocating motion mechanism, so it is not convenient to horizontally pull the serrated knife during cutting for fast cutting, reducing the cutting speed of the saw bed structure. Second, since the outer surfaces of some bars are cylindrical, it is easy to have the situation that the fixed bar is not firmly fixed during the cutting process. There is no fixing component, so it is not convenient to firmly fix the cylindrical bar, which in turn affects the cutting of the bar. Summary of the Utility Model

[0005] The purpose of this application is to provide a metal band saw for bar cutting to improve the problems that the existing saw bed structure is not convenient to horizontally pull the serrated knife for fast cutting during cutting and is not convenient to firmly fix the cylindrical bar.
