SU1518060A1 - Arrangement for working flat blanks - Google Patents

Abstract

The invention relates to the processing of metals by pressure and can be used for the automation of stamping production. The purpose of the invention is to improve the reliability and performance of the processing of flat blanks. The manipulator arm simultaneously places three blanks on the press revolving disk. During the three working strokes of the press ram, the arm of the manipulator must complete only one cycle of extraction and loading of the blanks. Such a relationship between the working moves of the slider and the arm is ensured by performing the actuator turning the arm of the manipulator in the form of a cylindrical cam connected through a gearbox with a revolving disk drive, and the actuator lifting and lowering the hand in the form of a crank-slider mechanism with an eccentric connected through the reducer to hand-rotated. The cam reducer reduces the number of working strokes of the arm by as many times as the blanks will be simultaneously placed in the disc slots. The eccentric reducer provides two cycles of lifting - lowering the hand in one turn cycle. 3 il.
