    模具在淬火冷却时要注意什么?

    来源:https://www.jnqhmj.com/ 日期:2021-12-17 发布人:admin


    模具在淬火冷却时应注意四个方面的问题。分别是冷却介质问题、冷却设备问题、模具表面覆盖层问题和工人操作技术问题。
    Four problems should be paid attention to when the die is quenched and cooled. They are cooling medium problem, cooling equipment problem, mold surface coating removal problem and worker operation technology problem.
    冷却介质问题主要是如何选择合适的冷却介质。目前常用的冷却介质有13大类,分别是空气、水、油、盐浴、铅浴、碱浴、无机盐水溶液、有机化合物水溶液、复合盐水溶液、复合有机化合物水溶液、复合油、矿物颗粒、金属制品。如何选择冷却介质需根据模具的材料、模具的大小和模具技术要求以及模具淬火工艺要求来确定。
    The main problem of cooling medium is how to select the appropriate cooling medium. At present, there are 13 categories of commonly used cooling media, namely air, water, oil, salt bath, lead bath, alkali bath, inorganic brine solution, organic compound aqueous solution, composite brine solution, composite organic compound aqueous solution, composite oil, mineral particles and metal products. How to select the cooling medium needs to be determined according to the die material, die size, die technical requirements and die quenching process requirements.
    冷却设备问题即为模具冷却提供各种服务的设备问题,它包括为冷却介质提供相应容器、输送设备、辅助设备以及测试设备等存在的隐患问题。这些设备存在的隐患问题,在热处理生产之前需要,以免影响模具生产,更要避免由此而导致模具出现质量缺陷。

    The problem of cooling equipment is the equipment problem that provides various services for mold cooling, including the hidden dangers of providing corresponding containers, conveying equipment, auxiliary equipment and test equipment for cooling medium. The hidden dangers of these equipment need to be solved before heat treatment production, so as not to affect the mold production, but also to avoid the quality defects of the mold.
    模具表面覆盖层问题关系到模具的淬火质量,除特殊要求外,模具在被冷却之前应尽快表面覆盖层,以避免出现模具表面硬度低且有大量软点或模具表面出现大量软点或模具表面硬度低现象。譬如盐浴加热时,更设法去掉模具表面的熔盐,提高模具的冷却能力,保证淬火组织。
    The problem of removing the covering layer on the die surface is related to the quenching quality of the die. In addition to special requirements, the surface covering layer shall be removed as soon as possible before the die is cooled, so as to avoid the phenomenon of low die surface hardness and a large number of soft spots or a large number of soft spots on the die surface or low die surface hardness. For example, when the salt bath is heated, try to remove the molten salt on the mold surface, improve the cooling capacity of the mold and ensure the quenching structure.
    工人操作技术问题直接关系到模具淬火质量,工人操作技术水平的高低在某些程度上直接决定了模具的淬火质量,或者直接决定了模具是否出现淬火缺陷。一般而言,有一定文化程度、有一定的工作历练、掌握了一定热处理技术的工人,在模具淬火方面出现的人为质量事故是交少的。
    The problem of workers' operation technology is directly related to the quenching quality of the die. The level of workers' operation technology directly determines the quenching quality of the die to some extent, or directly determines whether the die has quenching defects. Generally speaking, senior workers with a certain education level, work experience and heat treatment technology have less man-made quality accidents in die quenching.
