Essay

The thesis aims to increase efficiency and reduction of costs of manufacturing process equipment exhaust hollow cylindrical parts based on the combined load, namely the use of stamps with rotating clamp. The methods of theoretical analysis of power load metal piece in the drawing dies with rotating clamp on the base of the joint solution of the equations of equi-librium and conditions of plasticity. The analytical modeling of the proposed process flowsheet power load. The complex of experimental studies have confirmed the possibility of obtaining hollow cylindrical parts that meet specifications. Results of experimental data on measurement efforts hoods and deformation of the workpiece confirm the reliability of the theoretical dependences. The theoretical and experimental data served badose for designing new process extracts hollow cylinders.
