Coil Slitting Machine, Slitter extrusion slitting is mainly synchronized with the speed and have a certain wrap angle with the bottom roller and adjust the convenient pneumatic blade composition, the material is mainly used DY-5, Cr12MoV, D2, LD, H13, W18Cr4V, SKD-11, H13 + W + Ni and other high-quality tool steel and high-alloy die steel and other materials, special heat treatment process, hardness up to HRC60-65, mainly used for automotive dual-phase high strength plate, hard titanium stainless steel, automotive high-strength steel plate, pickling high strength plate, etc. It is mainly used for automobile duplex high-strength plate, hard titanium stainless steel, automobile high-strength steel plate, pickling high-strength plate, etc.. ... Plate slitting and various slitting machines.
There is no good blade, only the right blade, the advantages and disadvantages of the slitter blade is relative, the cutting effect of the blade key in the application. Slitter cutting line cutting from the upper and lower two disc knives cut line direction cutting, this cutting knife comparison is convenient, the upper disc knife and the lower disc knife can be based on the cutting width request, it is very simple to adjust the position directly.
Here are a few common principles of selection:
1. Material
High Speed Steel (HSS): Good wear resistance and hardness, suitable for high speed cutting.
Tungsten carbide (e.g. tungsten steel): with higher hardness and wear resistance, suitable for cutting harder materials.
Tool steel: Less expensive and suitable for general purpose cutting.
2. Hardness
The hardness of the insert should be selected according to the hardness of the material to be cut. Too low a hardness may cause the blade to wear out too quickly, while too high a hardness may make it brittle.
3. Blade size
According to the model of the slitting machine and the processing requirements, select the appropriate size of the blade in terms of outer diameter, inner diameter, thickness, etc. The blade size should be compatible with the equipment. The size of the blade should be compatible with the equipment to ensure stable installation and operation.
4. Blade surface treatment
Titanium plating: Enhance the wear resistance and oxidation resistance of the blade. Nitriding treatment: Improve the hardness and wear resistance of the blade surface.
5. Cutting accuracy of blades
Precision indicators such as parallelism and concentricity of the blade directly affect the quality of slitting. High-precision blades can ensure the smoothness and dimensional consistency of the slitting edge.
Correctly handle the relationship between machine blade performance, price and stability. In the relationship between the three, the stability of the blade is life, and cost-effective is the goal to pursue. Not one-sided pursuit of imported blades, only the pursuit of suitable for their own machine blades.
