    热作模具钢运用期间的功能介绍

    来源:/ 日期:2022-09-06 发布人:admin


    热作模具钢是指适宜于制作对模具进行热变形加工的模具用的合金工具钢,如热锻模、热挤压模、压铸模、热镦模等。由于热作模具长时间处于高温高压条件下工作,因此,要求模具材料具有高的强度、硬度及热稳定性,特别是应有高热强性、热疲劳性、韧性和耐磨性。下面来讲讲山东热作模具钢运用期间的功能。
    Hot working die steel refers to alloy tool steel suitable for making dies for hot deformation processing, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. Because the hot working die works under high temperature and high pressure for a long time, the die material is required to have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue, toughness and wear resistance. Let's talk about the functions of Shandong hot work die steel during its application.
    热作模具钢的运用功用请锤锻模具锤锻模具作业时遭到很大的压力和冲击载荷效果,而且冲击频率很高,模具型腔外表遭到高温模具的不时加热,可使模具升温到300℃~400℃,部分温度抵达500℃~600℃。
    The application function of hot work die steel is to use hammer forging die. The hammer forging die is subjected to great pressure and impact load effect during operation, and the impact frequency is very high. The surface of the die cavity is heated by the high-temperature die from time to time, which can make the die temperature rise to 300 ℃ ~ 400 ℃, and some temperatures reach 500 ℃ ~ 600 ℃.
    锤锻模具对模具钢的功用请求是:具有较高硬度和很好的耐性;具有很好的耐磨性和耐冷热疲惫性;由于模具尺寸比拟大,应具有很高的淬透性。热挤压模具热挤压模具的作业条件比拟差,一同承受紧缩力和弯曲力,脱模时还承受必定的拉应力,还遭到冲击载荷的效果。
    The functional requirements of hammer forging die for die steel are: high hardness and good resistance; It has good wear resistance and cold and hot fatigue resistance; Due to the large size of the mold, it should have high hardenability. Hot extrusion die the working conditions of hot extrusion die are relatively poor, and they bear tightening force and bending force together. When demoulding, they also bear certain tensile stress and impact load.

    模具与高热模具触摸时辰较长,使其受热温度比锤锻模具温度更高。热挤压模具对模具钢的功用请求是:具有较高的热稳定性,有很好的抗冷热疲惫强度,有较高的耐高温强度和满足的耐性。压铸模具压铸模具的失效方式有热疲惫开裂、热磨损和热熔蚀。
    The mold and the high-temperature mold touch for a long time, so that its heating temperature is higher than that of the hammer forging mold. The functional requirements of hot extrusion die for die steel are: high thermal stability, good cold and thermal fatigue strength, high temperature strength and satisfactory resistance. The failure modes of die-casting die include thermal fatigue cracking, thermal wear and thermal erosion.
    压铸模具对模具钢的功用请求是:具有较高的耐热性和很好的高温力学功用;具有很好的耐冷热疲惫性和较高的导热率;具有很好的抗氧化性和耐蚀性;具有较高的淬透性。凹模的硬度为56~60HRC,但请求耐性较高。
    The functional requirements of die-casting die for die steel are: high heat resistance and good high-temperature mechanical function; It has good cold and heat fatigue resistance and high thermal conductivity; It has good oxidation resistance and corrosion resistance; It has high hardenability. The hardness of the female die is 56 ~ 60HRC, but it requires high resistance.
    此外热作模具在工作时承受着很大的冲击力,模腔和高温模具接触,反复地加热和冷却,其使用条件其恶劣。为了满足热作模具的使用要求,热作模具钢应具备下列基本特性,较高的高温强度和良好的韧性。热作模具,尤其是热锻模,工作时承受很大的冲击力,而且冲击频率很高,如果模具没有高的强度和良好的韧性,就容易开裂。关注我们网站,了解更多内容!
    In addition, the hot working die bears a great impact force when it is working. The die cavity contacts with the high-temperature die and repeatedly heats and cools. Its use conditions are very poor. In order to meet the use requirements of hot work die, hot work die steel should have the following basic characteristics: high high temperature strength and good toughness. Hot working dies, especially hot forging dies, bear a lot of impact force when working, and the impact frequency is very high. If the dies do not have high strength and good toughness, they are easy to crack. Follow our website Yes, learn more!
