拉丝加工(如图一所示)常发生断线,钢丝烧伤,线材拉毛等缺陷。其中拉丝模单侧磨损造成的线材拉毛是拉丝中常见的缺陷之一。一、拉丝模的结构和拉丝的工作原理图二是拉丝模的结构,硬质合金模芯6被牢固地热镶或钎焊在钢套5内。模芯共由四部分组成:导入口,1变形带2,它是模具容易磨损的部位, Wire drawing (as shown in Figure 1) often broken, wire burns, wire drawing and other defects. One of the wire drawing brushes caused by wear on one side is one of the common defects in wire drawing. First, the structure of the drawing die and drawing the working principle Figure two is drawing die structure, carbide core 6 is firmly hot set or brazed in the steel sleeve 5. Mold core consists of four parts: the import port, a deformation zone 2, it is easy to wear mold parts,
