Cross

What is the effect of the cross-cutting blade?

The cross cutter is a carton processing machine. The cross-cutting machine in the corrugated board production line is the mechanical equipment for the cutting of the finished cardboard. The technical performance and the adjustment of the equipment directly affect whether the cutting size of the finished paperboard is accurate, whether the pressure line is broken and whether the appearance of the slit is smooth and beautiful. The cross-cutting machine blade is applied to the cross-cutting machine, and the cross-cutting machine is one of the important single machines of the cardboard production line. The cross-cutting machine is divided into mechanical cross-cutting machines due to different transmission control methods.

Cross-cutting machine blade picture machine and computer controlled cross-cutting machine. The computer cross-cutting machine is controlled by the industrial control computer. According to the set length, the cutter shaft is controlled to cut the cardboard, and the precision transmission of the mechanical part can control the cutting error within ±1mm. The computer controlled cross cutting machine has a spiral knife cross cutting machine and a straight knife cross cutting machine. The spiral cutter cross-cutting machine is more suitable for high-speed cutting of thick cardboard, and the cutting paper is stable, the blade has a long service life, and the blade should be made of high-speed steel.

There are two kinds of cutting blades in China, and the whole cross-cutting knife is inlaid with a cross-cutting knife.

The overall cross-cutting knife is made of SKD11, CR12, 9CRSI and other materials. The heat treatment grinds the knife edge, HRC50-58 degrees, the material is not the same hardness. The blade generally has a low service life and the blade edge is not sharp enough. Precision materials do not work well.

Inlaid cross-cutting knife refers to the HSS high-speed steel inlaid with knife edge. The tool body is made of grinding steel SKD11. The heat treatment is used to grind the knife edge. The HRC is 60-63 degrees. The HRC of different high-speed steel is different. This kind of blade generally has a high service life. Everyone knows that the high speed is high. The steel has high hardness and high toughness and is suitable for high-speed cutting. Even if cutting some high-precision materials, the cuttings are smooth and burr-free and durable.
