Abstract
New methods of manufacturing U-shaped screw transport and technological working bodies (STTWBs) are considered in this paper, in particular, by stamping and winding a sheet with U-shaped indentations on a frame using a wedge; a solid forming shaft and a forming shaft with U-shaped indentations; execution of U-shaped indentations on the pipe blank; winding STTWBs U-shaped profile using rectangular blanks. The main factors that affect the technological design of U-shaped STTWBs and the requirements for them are found. The most suitable structural materials for manufacturing U-shaped STTWBs, the related materials (lubricants), and press equipment are proposed. The technological features of the design parameters of STTWBs made in different ways are also determined.
