The application of knife plates in specific scenarios

As a multi-functional wear-resistant component, the knife plate is widely used in the fields of construction machinery and industrial processing. The following is an analysis of typical scenarios and technical key points:

I. Construction machinery field

Loader bucket application ‌

The medium manganese alloy steel knife plate (hardness HB550±15) is adopted, and the V-shaped cutting edge design reduces the cutting resistance, making it suitable for high-intensity excavation operations such as earthwork and ore ‌.

The modular design supports the rapid replacement of bucket teeth and auxiliary knife plates, enhancing the continuity of operations in scenarios such as mines and construction sites ‌.

Shield machine cutter head system ‌

The composite cutterhead is equipped with 120 high-strength alloy cutting tools (such as the "Ningyang 2" shield machine), designed for preventing mud cake formation in clay strata, and the cutterhead opening rate reaches 45%‌.

The six-spoke + panel structure takes into account both tunneling efficiency and the convenience of tool replacement, making it suitable for urban subways passing through complex strata.

Ii. Industrial processing field

Thread rolling machine knife plate ‌

The 16mm thick ball tool plate is specially designed for cold extrusion forming of straight-grain/mesh-grain workpieces. It reduces frictional resistance through ball support and improves the processing accuracy of threads ‌.

Pipe cutting equipment ‌

The cutter plate of the articulated pipe cutting machine is made of hard alloy and can cut pipes with diameters ranging from DN200 to DN1200. Compared with traditional flame cutting, its efficiency is increased by more than three times ‌.

Iii. Special Process Scenarios

Packaging industry knife plate ‌

Customized knife plate lines (0.5-1.5mm knife height) are used to cut irregular box bodies, and in combination with embossed plates, high-end packaging processes such as embossing and hot stamping are completed ‌.

Leather processing ‌

Cowhide tool plates, ground with 5000-8000 mesh green wax, are used for maintaining the sharpness of cutting tools and are suitable for precision tool processing scenarios ‌.

Note ‌ : Different scenarios have differentiated requirements for the material and process (such as wear-resistant steel, hard alloy), structural design (modular, composite), and maintenance methods of the knife plate ‌.
