The common materials and hardness of the blade of the sundering machine

The blade in the slitting machine is a very important part of the slitting machine, because it is related to the slitting effect of the slitting machine. So, let's have a good study, in order to be able to strip machine blade and strip machine itself, have a comprehensive knowledge and understanding, so that we can come to the expected learning policy, and to benefit themselves.

Sprocket blade, its application, is mainly used for film, paper, cigarette, leather and printing and metal sprocket. Therefore, it is mainly used in the mechanical strip production line, used for longitudinal cutting and xining plate and so on.

1. The materials and requirements of the slitting machine blade

The materials that can be used by the slicing machine blade are 9CrSi, 6CrW2Si, Cr12MoV, W18Cr4V and T10 and H13, etc. In addition, the data are also heat treated and other processes, in order to have good hardness, as well as some other good functions.

The main requirement of the slitting machine blade is that the blade cutting should be smooth and flat, and the edge should be sharp and wear resistant, so as to have a good slitting effect.

2. What common sense should we know and grasp on the blade of the slitting machine?

On the blade of the slitting machine, its requirements are not low. And in the thickness of the product, there are corresponding requirements. Generally, its flatness should be within 0.003mm.

In addition to the blade, the slitting knife group shall include spacer and gasket, etc. Through their use, can make the blade between the appropriate width and horizontal open space. Among them, the thickness scale of the gasket is generally 0.8 -- 150mm. The thickness tolerance of the blade is required to be within 0.003mm, so that it can be done.

3. Stainless steel strip machine, the blade hardness, is generally to reach how much ah?

Stainless steel sprocter blade hardness, its requirements on hardness, specifically depends on the thickness of stainless steel plate. If the thickness of the steel plate is less than 1mm, the hardness of the blade is higher. However, it should be noted that the hardness of the blade of the splitting machine can not be too high to avoid the phenomenon of collapse.
