A device for feeding sheet material to the treatment area operates as follows.

Sheet billet 60 is placed on the feed neyvodvod roller conveyor 64 (figure 1). The electric motor 7 is turned on and the carriage 1 along the guides 4 is supplied to the workpiece 60. The electric motor 7 is turned off and the working medium is fed into the external cavity of the power feed cylinder 14, mechanism 10. The housing of the power cylinder 14 moves in the direction of the slide P1IM 12 in the direction of the sheet. billet 60 to its entrance by clamping levers 17 and 18, which are in the open (initial) position (Fig. 2). At the same time, the adjusting screw 28 is adjusted so that the working surface 25 of the lower clamping lever 18 is located below the plane of the sheet 60 and does not cling to it. After the sheet blank 60 is positioned between the clamping levers 17 and 1, the supply of the working medium into the external cavity of the supply power cylinder .14 is stopped and the working medium is fed into the external shaft of the clamping power cylinder 23, moving the piston 22 to the right, while its stem cavity connected with a drain. The rod 21, outwardly, rotates the upper clamping lever 17 on the axis x 20 and t9 and the working surface 24, moving down to the sheet blank 60, comes into contact with it. Thereafter, the connection of the pinhole of the clamping ram 23 with the drain is interrupted and the pressure in both cavities of the cylinder is balanced. Upon further supply of the working medium into the external cavity of the clamping power cylinder 23, its body, overcoming the resistance of the adjustable support 29, begins to move to the right, thereby turning the lower clamping lever 18 on axis 26, t9, which interacts on the rod 35 (Fig. ), depressing it, compressing the spring 33 in the threaded adjusting sleeve 31 of the swaged support 29. Turning on axles 26 and 19, the lower clamping lever 18 enters its working surface 25 into contact with the sheet, the blank 60 and the last 23014

clamped between two clamping levers 17 and 18 (figure 2). The flow of the working medium into the external f-cavity of the clamping power cylinder 23 is stopped and the working medium is fed into the rod cavity of the feed power cylinder 14, the body of which moves to the right along the guides 12. 0 Together with the body of the feed power cylinder 14, the clamping levers 17 and 18 with the clamped sheet billet 60 until the latter rests its edge against the 5 base surfaces 59 of the lower jaws 42 (Fig. 3) of the clamping mechanisms 8 and 9, which are in the initial position (clamping jaws 41 and 42 edeny). Since the working surfaces 0 and 24 and 25 of the clamping arms 17 and 18 (FIG. 2) of the mechanism 10 are made in the form of cones or hemispheres, the clamping of the workpiece 60 occurs at a point that allows it R

rotate around this clip point. This ensures the self-installation and precise basing of the sheet blank 60 on the clamping surfaces 59. A closed sheet blank 60 acts on the limit switches 61 and 62 (FIG. 1), which command to stop the supply of working medium to the rod cavity of the feed power cylinder 14 (FIG. 2) 5 and for supplying the working medium to the rod end of the power cylinders 56 (FIG. 3), the clamping mechanisms 8 and 9.
