Forging die is a die used in the forging process. The die steel material produces plastic deformation in the forging die under the action of external force, so as to obtain the parts with the required shape and size. Forging die can be divided into hot forging die, warm forging die and cold forging die according to the temperature of forging die steel. The main technical development direction of forging die is to improve the die design level, adopt new die steel materials and use efficient and high-precision processing means, so as to realize the high precision of forging under the condition of high die life.

锻造模具分类：

Forging die classification:

、按照载荷特性分类根据模具承受的载荷性质或设备类型的不同，可将模具材料分为冲击载荷(锻锤、螺旋压力机或称螺旋锤)和静载荷(液压机、机械压力机、辊锻机和辗环机)模具材料。其中锻锤热锻模具材料主要包括锻钢整体锻模(大、中、小型和校正模块)材料、镶块锻模(铸钢模体和锻钢镶块)材料以及锻钢和铸钢堆焊锻模(锻钢和铸钢模体及堆焊模膛)材料;压力机热锻模具材料主要包括整体模具材料、预应力镶块模具材料和拼分模模具材料等。

According to the classification of load characteristics, the die materials can be divided into impact load (forging hammer, screw press or screw hammer) and static load (hydraulic press, mechanical press, roll forging machine and ring rolling machine) according to the load nature borne by the die or different equipment types. The forging hammer hot forging die materials mainly include forging steel integral forging die (large, medium, small and correction module) materials, insert forging die (cast steel die body and forged steel insert) materials, and forged steel and cast steel surfacing forging die (forged steel, cast steel die body and surfacing die chamber) materials; The hot forging die materials of press mainly include integral die materials, prestressed insert die materials and split die materials.

、按照锻压工艺和工序特点分类按照锻压工艺和工序特点可以分为模锻(终锻、预锻)模具材料、挤压模具材料、切边模具材料、校正模具材料、精压模具材料、辊锻模具材料、辗环模具材料和胎模锻模具材料等。

According to the characteristics of forging process and process, it can be divided into die forging (final forging, pre forging) die material, extrusion die material, trimming die material, correction die material, fine pressing die material, roll forging die material, ring rolling die material and tire die forging die material.

、按照模具结构特点分类按照模具结构特点可以分为整体模具材料、预应力模具材料、拼分模模具材料、挤压凹模、冲头和顶杆模具材料以及辊锻扇形镶块模具材料等，其中预应力模具材料又可以分为模体材料和 镶块材料。

According to the characteristics of die structure, it can be divided into integral die material, prestressed die material, split die material, extrusion die, punch and ejector rod die material and roll forging sector insert die material. Among them, prestressed die material can be divided into die material and insert material.

实际上,模具材料的这些分类方法都是为了工作方便，山西中信重工，仅反映了模具材料特点的某一个方 面,没有一种分类方法能够反映具体模具材料的整体特性,况且各类模具材料之间还有交叉。

In fact, these classification methods of mold materials are for the convenience of work. Shanxi CITIC Heavy Industry only reflects one aspect of the characteristics of mold materials. No classification method can reflect the overall characteristics of specific mold materials. Moreover, there are intersections between various mold materials.

因此，这些模具材料的类别只能作为选择模具材料时的导向和参考，在实际选择模具材料时，还要根据具体锻压工艺、模具用途和工况条件作综合分析。

Therefore, the categories of these die materials can only be used as a guide and reference when selecting die materials. When actually selecting die materials, a comprehensive analysis should be made according to the specific forging process, die use and working conditions.
