MODERNIZATION OF AUTOMATIC MACHINE FOR PRODUCING TIN CONTAINER CASES

The article provides a brief description of the technological process for manufacturing tin body products on an automatic rolling and welding machine. The enterprise's problem of upgrading foreign welding equipment is identified, a number of tasks are defined, the solution of which will improve the machine control system by introducing modern programmable logic controllers. During the research, the manufacturing process of a typical product - a shell (body) of a tin container - was studied in detail, the main working areas of the rolling and welding machine were determined, and a cyclogram of its drives was developed. Based on these data, a number of conditions and restrictions were adopted aimed at increasing the stability of the process and minimizing possible losses of machine time. To implement the process taking into account all the restrictions and requirements, a list of necessary sensors was formed and their position in the machine was determined. A time diagram of the passage of the workpiece through the welding unit was developed, allowing for precise adjustment of the operation of the specified drives and sensors, determining the productivity of the welding process and the quality of the resulting product. Programs have been developed to control the welding machine, including the welding process itself, as well as the interface of the control system operator panel, allowing a series of experiments to be carried out to determine the optimal welding modes.
