SCREW AUGER FORMING MACHINE Russian patent published in 2019 - IPC B21C37/26 B21D11/14 

FIELD: machine building.

SUBSTANCE: screw auger forming machine comprises a base supporting a workpiece support in the form of an open ring, an oil station with a control unit, comprising a control console connected through the hydraulic cylinder to the moving part of the press, which, through a supporting support and a matrix support plate, compresses the workpiece between the forming plates of the matrix and forms a screw spiral by acting on the fixed part of the press with a hydraulic cylinder. Supporting support is made in the form of a height-adjustable bracket, and the matrix is in the form of a set of hardened plates made in the form of rectangular trapezoids. Matrix support plate is made in the form of a steel hardened plate in the form of an isosceles triangle. Molding plates are installed in slots of matrix support plate, which is installed on press.

EFFECT: enlarging technological capabilities of the machine due to possibility of calibration of manufactured products depending on properties and composition of steel, as well as increased accuracy of their shape.
