DEVELOPMENT OF ENERGY AND RESOURCE SAVING TECHNOLOGIES OF PROCUREMENT PRODUCTION

The article presents the results of development and research energy- resource-saving low-waste technologies pressure metal processing (OMT). When developing OMT processes, it is important to expand technological capabilities production parts complex shape. This facilitated by local deformation processes. purpose this study improve quality parts, save material, energy labor resources based on calculation design rolling stamping processes with an assessment deformability material workpieces. For purpose, a method was developed for calculating rational routes in which provides: reduction cost due power equipment, number transitions elimination scrap from destruction; improving products formation favorable microstructure reducing anisotropy mechanical properties limiting resource plasticity. It shown that accuracy dimensions workpiece after depends scheme, tool its setting, roughness surface product lubrication. rolling, ensured according 7-11, surfaces, if requirements are met, μm. On example reshaping square sheet blanks into round ones, proven degree planar decreased 70-80% relative drop yield strength plane 0.10-0.15 0.03-0.05, as well increase ultimate tension 8-10% uniform 5-8%. drawing cylindrical reshaped blanks, size festoons decreases 2-2.5 times, increases 10-15%. At same time, difference wall thickness along perimeter elongated decreases, decrease height becomes linear.
