我厂制造与应用硬质合金挤压模已有近二十年的历史,在无产阶级文化大革命以后,为了适应生产发展的需要,开始试用硬质合金制造冷挤压模具。通过几年的实践、认识、再实践、再认识,不断总结经验,对硬质合金冷挤压模的结构、模套材料热处理,以及模腔形状尺寸进行多次改进,现已正常用于生产。使用寿命较原轴承钢制的挤
I plant the production and application of carbide extrusion die has been nearly 20 years of history, after the Great Proletarian Cultural Revolution, in order to meet the needs of production and development, began to test the use of hard alloy cold extrusion die. Through several years of practice, understanding, practice, re-understanding, and constantly sum up experience, the structure of the die cold carbide die, die cover material heat treatment, as well as the shape of the cavity size many improvements, is now normally used in the production . The life of the original bearing steel squeeze
