Unreasonable reciprocating feeding layout method and too small overlap value often cause sharp wear of the mold or damage to the convex and concave dies. Therefore, while considering improving material utilization, it is necessary to reasonably select the layout method and overlap value according to the processing batch, quality requirements and mold matching clearance of
Fuel Car parts to improve the life of
New Car molds.
The influence of New Car mold materials on mold life is a comprehensive reflection of material type, chemical composition, organizational structure, hardness and metallurgical quality. The life of New Car molds of different materials is often different. For this reason, two basic requirements are put forward for the material of die working parts:
① The performance of the material should have high hardness (58~64HRC) and high strength, high wear resistance and sufficient toughness, small heat treatment deformation, and certain hot hardness;
② Good process performance. The processing and manufacturing process of Fuel Car die working parts is generally more complicated. Therefore, it must have adaptability to various processing technologies, such as forgeability, machinability, hardenability, hardenability, quenching crack sensitivity and grindability. Usually, mold materials with excellent performance are selected based on the material properties, production batch, precision requirements, etc. of New Car stamping parts, while taking into account their processability and economy.
