Features of Manufacturing Spiral Corrugated Blanks From Various Profiles of Corrugations

Abstract

The leading role in the field of using spiral mechanisms plays the design and manufacture of corrugated spiral working bodies, which are widely used in mixers, heat exchangers, machines for borontation of free abrasives, in the confectionery and pharmaceutical industries, etc. Increasing the requirements to the design and technological parameters, quality, reliability and durability, enhanced technological capabilities require deep analysis of existing structures and technologies of their production and the development of scientific research on theoretical and experimental studies and their successful implementation in production. The paper focuses on the development and implementation of new advanced technological processes of spiral corrugated and ring blanks. The results of theoretical and experimental research were based on the development and analysis of technological schemes for the formation of screw corrugated blanks in order to improve the mixing of bulk materials. The functional and structural and technological features of spiral corrugated blanks manufacture and the designing of the appropriate technological equipment and facilities with the withdrawal of the analytical dependences for determination of treatment regimes. The analytical dependences for determination of power and structural parameters of technological process of bending blanks between two cylindrical gear cross-sectional toothed wheels. Characteristics curves of spiral corrugated blanks on the basis of width and thickness of the lines and the workpiece step of 1 ... 3 mm thickness and with 15 ... 25….30 mm width are given in the paper. The results of the experiment show that labor productivity will increase by 20-30% in manufacturing, 2-3 times in control operations
