我们在生活中总是使用各种各样的产品,而这些产品实际上是由特定的模具模制而成的。而且,不同的产品具有不同的模具。这些模具使用时非常方便,已经形成了一批工业产品。冷挤压模具就是这样一种模具,它使用某种冷挤压技术来制造模具并将其发送到市场上进行销售。
We always use a variety of products in our lives, and these products are actually molded by a certain mold. Moreover, different products have different molds. These molds are very convenient when used, and have formed a batch of industrial production. The cold extrusion die is such a die, which uses a certain cold pressing technology to make the die and send it to the market for sale.
冷挤压模的挤压成型是在强大的三向压缩应力状态下完成的。冲头不仅承受强大的压缩应力,而且还要承受各种不平衡的侧向力,并且力是复杂的,尤其是在压力集中在冲头尺寸变化的地方,容易产生脆性断裂,但模具可能会破裂和破裂,并且由于剧烈的金属流动会严重损坏型腔。冷挤压模具的结构尺寸,工艺,模具加工和润滑对模具的寿命有很大影响,但是首先,我们必须注意材料的选择和热处理工艺。
The extrusion molding of the cold extrusion die is completed under a strong three-way compressive stress state. The punch is not only subjected to strong compressive stress, but also subjected to various unbalanced lateral forces, and the force is complex, especially in The stress is concentrated at the place where the size of the punch changes, which is easy to produce brittle fracture, while the die may burst and crack and the mold cavity is severely worn due to the violent metal flow. The structure size, process, mold processing, and lubrication of the cold extrusion die have a great impact on the life of the die, but first, we must pay attention to material selection and heat treatment process.
