Аннотация. В статье рассматривается двухкоординатный станок сварки. Подобное оборудование используется с целью получения сварочных швов на различных элементах металлоконструкций высокого качества. Основной недостаток имеющегося оборудования заключается в том, что работа на данном станке в настоящее время выполняется вручную. Это операция является достаточно опасной и монотонной. Кроме того, в качестве основного привода системы используется гидропривод. Обоснована замена гидропривода двухкоор динатного станка сварки на электропривод с целью повышения КПД всей системы. Выполнена разработка автоматизированного электропривода двухкоординатного станка сварки закладных, управляемого на базе программируемого логического контроллера. Проведено проектирование электропривода объекта. Реализован выбор необходимых элементов разработанной системы автоматизации. На основе технологического процесса разработан алгоритм, который позволяет автоматизировать процесс сварки закладных. Данный алгоритм предусматривает необходимые меры безопасности, осуществляя самодиагностику на этапе запуска системы. С целью проверки работоспособности разработанного алгоритма выполнено моделирование автоматизированного электропривода с помощью программного обеспечения Matlab Simulink. Система содержит два внутренних и три внешних контура, осуществляющих контроль необходимых параметров: скорос ти, тока, момента, потокосцепления и усилия. Получены динамические характеристики представленных параметров, подтверждающие работоспособность разработанной системы автоматизированного электропривода. Проведен экономический расчет предлагаемой к внедрению системы автоматизации. Суммарные затраты на модернизацию составят порядка 55 тыс. рублей при сроке окупаемости около одного года.
<p>In recent years, there has been a great interest in the transition to digital and automation services for dangerous and menial working processes. Due to its MH50-35 industrial robot, Motoman's properties allow us to improve the control system of an electric drive for industrial robots. The structure of the electric drive for six-axis robot manipulator performance can be superior to conventional Drive Control servos for motor excitation, and a novel automation system can be implemented for its servo performance. To solve these issues, we propose an optimization strategy that allows us to achieve an increase in productivity and labor safety in the industry, reduce the percentage of defects, guarantee product uniformity, and reduce the prime cost of production of items. Ideal conditions were anticipated using a mathematical model. In this study, by using a statistical model, the ideal conditions were synthesized. The optimization of the control system of an electric drive for industrial robot analysis was carried out, and our findings suggest using this model in industrial production to elucidate problems such as high accuracy and speed indicators.</p>
Two-coordinate welding machine is used to obtain welds on various elements of high quality metal structures. The main disadvantage of the existing equipment is that the work on this machine is currently performed manually. This operation is quite dangerous and monotonous. In addition, hydraulic drive is used as the main drive of the system. Replacement of the hydraulic drive of a two-coordinate welding machine with an electric drive is substantiated in order to increase the efficiency of the entire system. The authors have developed an automated system for a two-coordinate machine for welding embeds, controlled on the basis of a programmable logic controller. A functional diagram of an automated electric drive for such machine was proposed. The design of the object’s electric drive was carried out. The necessary elements of the developed automation system were selected. On the basis of the technological process, an algorithm has been developed that allows automating the process of embeds welding. The developed algorithm provides the necessary security measures, carrying out self-diagnostics at the stage of system startup. In order to check the performance of the developed algorithm, an automated electric drive was simulated using the MATLAB Simulink software. The developed system contains two internal and three external circuits that control the required parameters: speed, current, torque, flux linkage and force. The dynamic characteristics of the presented parameters are obtained, confirming the operability of the developed automated electric drive system. An economic calculation of the automation system proposed for implementation has been carried out. The total costs for the modernization will amount about 55 thousand rubles with a payback period of about one year.
