Description

Ductile iron cutting tool

Technical Field

The utility model belongs to the technical field of ductile iron, and in particular relates to a ductile iron cutting tool.

Background Art

Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. It was developed in the 1950s. Spheroidal graphite is obtained through spheroidization and inoculation, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness. Therefore, ductile iron has higher strength than carbon steel and is known as the main representative of "iron replacing steel". Ductile iron is widely used in the manufacture of various parts with complex forces, high strength, toughness and wear resistance requirements, such as pressure pipes and accessories, automotive parts, agricultural machinery and construction equipment.

At present, in the process of cutting ductile iron workpieces, it is usually necessary to manually fix the workpieces. Although this fixing method is easy to operate and efficient, it has certain safety hazards. Because the stability of manual fixing is poor, it is easy to cause position deviation during the cutting process, resulting in processing failure or even damage to the workpiece. Therefore, finding a safer and more stable workpiece fixing method is of great practical significance for improving the cutting efficiency and quality of ductile iron workpieces.
