SHEET-STAMPING AUTOMATIC PRESS Russian patent published in 2008 - IPC B30B1/26 B21D43/11 

FIELD: technological processes.

SUBSTANCE: automatic press contains connecting rod, working table, die plate and die block. Drive of eccentric shaft is installed above the working table. In the working table mechanisms of stamped tape braking are fixed before and after die block. Automatic press is equipped with mechanism of control of die block closed height. Eccentric bushing is mounted on eccentric shaft journal. Concentricity of bushing is equal to concentricity of shaft journal. Bushing has the possibility of rotation depending on pitch of stamped tape supply and fixation by means of end tooth clutch. At that summary eccentricity of shaft journal and bushing changes from 0 to maximum value. Connecting rod head covers eccentric shaft through bearing. Die plate is movably installed in guides of working table and is joined to connecting rod. In the latter top part of die block is fixed.

EFFECT: higher efficiency of stamping process and simplification of press design and device for tape supply.
