Heat treatment requirements and processes for mold parts of LiuGong excavator accessories

2025-04-15

The heat treatment processes for different materials vary greatly. How is the heat treatment of mold parts carried out? Today, LiuGong excavator parts manufacturer will answer your question:

Heat treatment requirements for each part of the punching die:

Processing requirement punching is one of the basic processes of cold stamping. It is a stamping process that uses a punching die to separate the punched materials on a press machine. Punching die is a type of LiuGong excavator accessory mold with a cutting edge. During punching, the cutting edge sinks into the material being punched, and is subjected to intense impact and friction from the material, causing severe wear and tear on the cutting edge after a period of use, from initially sharp to eventually round and dull, affecting the quality of subsequent products. In order to ensure the long-term stability of the quality of the product parts, it is required that the convex die of the punching die has high wear resistance, as well as certain compressive strength, bending strength, and impact cutting ability. As for the concave mold, besides the seemingly low requirement for flexural strength, its requirements for compressive strength and toughness are higher than those for the convex mold. Regarding the above requirements for the punching dies of LiuGong excavator accessories, in addition to correctly selecting the steel used for the convex and concave dies, there should also be a reasonable heat treatment process to ensure the hardness, toughness, and other requirements after heat treatment. Both are indispensable.

Organization of Heat Treatment Sequence for Stamping Die Forming Parts of Liugong Excavator Accessories

The process sequence of the heat treatment process organization that requires electrical machining after final heat treatment quenching is:

Casting → Heat treatment annealing → Mechanical rough machining → Heat treatment quenching and tempering → Electrical machining (EDM perforation or wire cutting) processing and forming → Clamp repair and assembly.

From this, it can be seen that the heat treatment process of LiuGong excavator parts is a very important and indispensable processing technology in die manufacturing. For stamping dies with precise requirements for directional and dimensional tolerances such as progressive dies and composite dies, it is not only necessary to adhere to the above process organization, but also to reduce heat treatment deformation. Stress removal treatment, quenching and tempering, and other heat treatment processes are often interspersed during processing.
