    模具钢在使用过程中造成模具爆裂的原因

    来源:https://www.jnqhmj.com/ 日期:2022-07-30 发布人:guanli


    在生产的过程中很多方面的原因都会引起模具钢爆裂。下面就综合分析下模具钢爆裂的原因,可供大家参考,望能解决在生产的过程中遇见的一些问题。
    In the production process, many reasons will cause the die steel to burst. The following is a comprehensive analysis of the causes of die steel cracking for your reference, hoping to solve some problems encountered in the production process.
    1.材质不好
    1. Poor material
    2.热处理:淬火回火工艺不当产生变形
    2. Heat treatment: deformation caused by improper quenching and tempering process
    3.模具研磨平面度不够,产生挠曲变形
    3. The grinding flatness of the mold is not enough, resulting in bending deformation
    4.设计工艺不合理
    4. Unreasonable design process
    5.线割工艺不佳
    5. Poor wire cutting process
    6.冲床设备的选用不准确
    6. Inaccurate selection of punch equipment
    7.冲压工艺不当
    7. Improper stamping process
    8.生产作业的使用不正确。
    8. Incorrect use of production operations.
    山东模具钢厂家认为不同材质的模具寿命往往不同。为此,对于冲模工作零件材料提出两项基本要求:
    Shandong die steel manufacturers believe that die life of different materials is often different. For this reason, two basic requirements are put forward for the materials of working parts of stamping dies:
    山东模具钢
    ①材料的使用性能应具有高硬度(58~64HRC)和高强度,并具有高的耐磨性和足够的韧性,热处理变形小,有一定的热硬性;
    ① The service 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 thermal hardness;
    ②工艺性能良好。冲模工作零件加工制造过程一般较为复杂.因而必须具有对各种加工工艺的适应性,如可锻性、可切削加工性、淬硬性、淬透性、淬火裂纹敏感性和磨削加工性等。通常根据冲压件的材料特性、生产批量、精度要求等,选择性能优模具材料,同时兼顾其工艺性和经济性。
    ② Good process performance. The processing and manufacturing process of working parts of stamping dies is generally complex, so it must have adaptability to various processing technologies, such as malleability, machinability, hardenability, hardenability, quenching crack sensitivity and grinding machinability. Generally, according to the material characteristics, production batch and accuracy requirements of stamping parts, the die materials with excellent performance are selected, taking into account their processibility and economy.
    由于冲压工序不同,工作条件不同,造成模具爆裂的原因是多方面的,上面就冲模的设计、制造及使用等方面综合分析模具爆裂的原因,并找出相应的改善措施。更多相关信息就来网站https://www.jnqhmj.com咨询吧。
    Due to different stamping processes and working conditions, the causes of die burst are various. The above comprehensively analyzes the causes of die burst from the aspects of die design, manufacturing and use, and finds out the corresponding improvement measures.
