Benefits of a draw plate with regular microrelief

Abstract

To improve drawing technology, cylindrical steel 45 rods (1810 HB ) of rated length 200 mm are investigated experimentally. These samples are machined with dimensionless accuracy up to 0.02 mm and surface roughness Ra = 0.144‐0.384 µ m. On the basis of the results in [1], 9 ie steel draw plates (58‐61 HRC ) with irregular and regular microrelief are used for drawing. The working channel of the draw plates is of diameter 20 +0.03 mm; the angles of the working and inverse cones is 5 ° ; and the width of the calibrating strip is 5 mm. The irregular surface microrelief of the draw plates is formed by grinding with a maximum-projection height H max = 7‐11 µ m. Regular microrelief is formed by means of a diamond instrument of radius 1.5 mm in the form of single-turn screw channels with a pitch P ch = 0.5 mm and depth D ch = 10 µ m. Longitudinal profilograms of the calibrating strips of the draw plate are shown in Fig. 1. Zero parameters of the regular microrelief ( D ch = P ch = 0) may be regarded as corresponding to irregular microrelief. The rated tension i r in plastic deformation varies in the range 0.1‐0.5 mm, with an increment of 0.1 mm. To estimate the influence of the lubricant and coolant fluid, we compare liquid lubricant (I-40 mineral oil) and plastic lubricant (a mixture of grease and fine molybdenum-disulfide powder). The drawing rate is around 1 m/min. The dependence of the drawing force q d on the actual tension i ac in plastic deformation, the lubricant, and the surface microrelief of the tool is shown in Fig. 2.
