Abstract

The issues of ensuring the accuracy of the filaments’ production for additive manufacturing using the electron beam energy at the stage of drawing of a workpiece made of 12H18N9T steel were considered. The reduction ratio varied in the range from e = 5 % to e = 67.5 %. Calculations showed that the dimensions of a workpiece for producing filaments with a diameter of O 1.3-0.09 mm was limited by O 4.27-0.17 mm. It was experimentally established that the diameter of a filament made of 12H18N9T steel after the last reducing step (1.3 mm) exceeded the allowable diameter (1.3−0,09 mm) and equaled to 1.37 mm. This deviation is probably induced by elasto-plastic strains occurring in the wire in the drawing process. To provide the required accuracy of the filaments with a diameter of O 1.3-0.09 obtained by drawing of 12H18N9T steel, it was recommended to grin the diameter of a die taking into account the magnitude of the elastic deformations, i.e. provide the diameter 0.05 mm smaller than required.
12H18N9T钢增材制造细丝在制造过程中保证精度的特点
考虑了利用电子束能量在12H18N9T钢工件拉深阶段保证增材制造细丝生产精度的问题。还原率在e = 5% ~ e = 67.5%之间变化。计算表明,加工直径为1.3 ~ 0.09 mm的细丝时,工件的尺寸受限于0.4.27 ~ 0.17 mm。实验证实,12H18N9T钢经最后一步还原(1.3 mm)后的长丝直径超过允许直径(1.3 ~ 0.09 mm),达到1.37 mm。这种偏差可能是由拉丝过程中发生的弹塑性应变引起的。为了提供12H18N9T钢拉伸得到的直径为O 1.3-0.09的长丝所需的精度,建议根据弹性变形的大小来调整模具的直径,即提供比要求小0.05 mm的直径。
