news
Release time: 2017-9-26
At present, the cross-cutting machine is mainly used for the cross-cutting of leather, paper, plastic film, rubber, PP, PVC, copper foil and aluminum foil. The quality of the blade directly determines the efficiency of the cross-cutting machine. Its device!
Crosscutting machine blade is used in crosscutting machine. About crosscutting machine is one of the important single machines for cardboard production line. Due to different transmission control methods, the cross-cutting machine is divided into mechanical cross-cutting machine blade picture machine and computer-controlled cross-cutting machine. The computer cross-cutting machine is controlled by an industrial control computer. According to the set length, the knife shaft is controlled to cut the cardboard. In addition, the precision transmission of the mechanical part can control the paper cutting error within the range of ± 1mm. Computer-controlled cross-cutting machines include spiral knife cross-cutting machines and straight knife cross-cutting machines. The spiral knife cross-cutting machine is more suitable for high-speed cutting of thick cardboard, and the cutting is stable, and the blade has a long life. The blade should be made of high-speed steel.
There are currently two types of cutting blades in China: overall cross-cutting knives and inlay cross-cutting knives.
The overall cross-cutting knife is stamped and formed using SKD11, CR12, 9CRSI and other materials, and the heat treatment grinds the knife edge, HRC50-58 degrees, the material is not the same, the hardness is the same, this blade generally has a low service life, and the knife edge is not sharp enough. Precision materials do not work well.
The inlaid cross-cutting knife refers to the cutting edge inlaid with high-speed steel HSS, the blade body uses abrasive steel SKD11, and the heat treatment is used to grind the blade edge, HRC60-63 degrees. HRC is different for different high-speed steels. This blade generally has a high service life. Steel has high hardness and toughness, which is suitable for high-speed cutting. Even if cutting some high-precision materials, the cutting edge is smooth, without burrs, and durable.
