What should be paid attention to in the selection of cemented carbide die tools
The die tools industry is an integral part of the high-tech industry. For example, the design and manufacture of integrated circuits cannot be done without precision progressive die for lead frames and precision integrated circuit die tools; die tools industry is also an important area of high-tech industrialization. Important changes have taken place in CAD/CAE/CAM technology. The improvement of die tools development and manufacturing levels is conducive to the adoption of CNC precision and efficient processing equipment; the application of advanced technologies such as reverse engineering, concurrent engineering, agile manufacturing, and virtual technology in the die tools industry It must also be grafted with high-tech such as electronic information to realize the industrialization of high-tech.
Cemented carbide mould
Cold heading is one of the advanced machining processes with less and no cutting. It has the characteristics of high production efficiency, energy saving, material saving, improved mechanical strength and precision of parts, and suitable for mass automated production. It has been widely used. In my country, the main cold heading process Used in fasteners, rolling bearings, roller chains, auto parts, military industry and other industries.
The cold heading forming of the parts is carried out on the cold heading machine.
1. Steel for cold heading dies under general load
The general load cold working die is mainly used for the production of cold heading parts with less complicated shapes, not too large deformation, and cold heading speed. The cold heading parts produced are low carbon steel or medium and low carbon steel parts.
2. Steel for heavy-duty cold heading die
The heavy-duty cold heading die is used to produce cold heading parts with large deformation and more complicated shapes. The cold heading parts use alloy steel or medium-high carbon steel with higher steel strength.
3. Steel for new type cold heading die
my country has introduced foreign steel grades or independently developed more than 10 new steel grades suitable for manufacturing cold heading dies. These new steel grades are characterized by high hardenability and hardenability, high compression yield point, and Good wear resistance and toughness.
