Design of Sinking Die of Rectangular Flat Steel Tube

  • 摘要: 介绍了改进的矩形扁钢管空拔模的设计方法,即空拔模长边面由平直面改进设计为弧形面,同时在入口过渡段和定径带衔接中心设计一定的椭球凹陷曲面,从而起到有效防止空拔模因热处理产生向外突变的作用,同时减小矩形扁钢管长边面在拔制过程中承受的压力和摩擦力,避免空拔后的矩形扁钢管出现长边面凹陷现象。
    Abstract: Described in the paper is the method for designing the modified sinking die of the rectangular flat steel tube. The design involves major modifications of the die, i.e., turning the original flat long-edge face into a curved one, and getting connecting part between the inlet transitional zone and the sizing zone having an oval-shaped concave curved surface. These modifications can not only prevent sudden outward change of the die itself due to the negative effect by heat treatment, but also reduce the pressure and friction imposed upon the long-edge face of the rectangular flat tube during the sinking process so as to avoid defective concavities on the long-edge faces of the tube after sinking.
