The invention relates to the cold working of metals by pressure and can be used to cut parts from flat blanks. The aim of the invention is the expansion of technological capabilities. I Figure 1 shows the proposed I device in the initial position, at I the moment of cutting the parts from the workpiece; Figure 2 is the same after ejecting the bottom blank from the magazine; The device contains a base 1, j installed on the basis of the power I cylinder 2, associated with the frame 3, which has a window for blanks. Frame 3 has a gate 4 and a retainer 5, | Above the frame 3, a magazine 6 1dl of workpieces 7 is mounted, and under the frame is a 1-slide bar 8 having recesses | under the retainer 5. The frame 3 is installed | With the possibility of reciprocating 9 base guides 1. Store 6 for workpieces 7 is mounted on a bus bar slot: a pick-up body and a loKHo rotary table 10, which is mounted on a rotary console 11. The stamp is provided with a tray J 2 for wastes and a matrix 13 with a failed window and mounted on press 14. On turntable 10 in Complete stop J5.

The device works as follows.

After the removal of the workpiece from the workpiece, the part falls into the failed window of the matrix, and the waste, located in the window of frame 3, is moved by the cylinder 3 with the frame 3 along the mirror of matrix 13 and dumped along the tray 1 2 into the waste box. The movable plate 8 connected by the latch 5 with the frame 3 moves together with the latter up to the stop 15 of the table 10 and stops under the failing window of the table 10, the ball of the latch 5 emerges from the first recess on its surface, and the frame 3 continues to move, while the slide valve the gripping body 4 of the frame 3 enters the groove of the table 10. Under the magazine 6, with the upper edge of the sliding gate the gripping body 4 pushes from under the foot the lower workpiece 7, which falls through the reclosing window of the table 10 into the window of the frame 3 blocked by the movable plate 8. Spring-loaded ball 5 in Odita at this point in the second groove on the surface of the strap that secures its relatively

frame 3. The cylinder 3 moves in the direction of the press cylinder 14 towards the working zone of the press 14, the bar 8 abuts against the end of the matrix 13, and the ball of the retainer 5 emerges from the recess on the surface of the bar. Frame 3 continues to move, the workpiece 7, which is located in the frame's in-window, moves along the surface of the stopped bar 8 and the mirror of matrix 13, overlapping the failed window of the matrix at the last moment of movement. The cycle is repeated.

After the store is emptied, the table turns to a predetermined angle, setting the new store with the blanks to the working position. Submission of the workpiece to the working area of the press continues.

If necessary, the swivel arm II with the table 10 is retracted to the side, opening access to the working area of the press for repair or for removing or for installing a stamp.

The invention makes it possible to create conditions for the full automation of the Process.
