SU1243870A1 - Apparatus for feeding sheet stock into working zone - Google Patents

Description

f

The invention relates to the cold processing of metals by pressure and can be used to feed sheet material into a zone, such as a press, for processing.

The purpose of the invention is to improve the reliability and expansion of technological capabilities by submitting sheets of various dimensions.

Fig. 1 schematically shows the proposed device for feeding sheet material to the treatment zone in Fig. 2 - view A in Fig. 1, in Fig. 3 a section B - B in Fig. 1.

The device consists of a base 1, on which the three-link lever mechanism 3, connected by a link 4 with a rod 5 of a power cylinder 6, a link 7 - with a rod 8 of a lifting table 9 and a link 10 - with a cylinder of a power cylinder 6, is mounted on an axis. , a mobile platform 11, carrying on itself removable cassettes 12 and connected to the power cylinder 13, a sliding mechanism 14. The device also contains a frame 15, guides 16, fixed on the frame 15, screw rods 17, mounted in the guides 16 and carrying spring-loaded dog grippers 18, support plates 19 with limiting rollers 20, a receiving table 21 fixed in the rails 22. The device comprises

also the workpiece 23, the power cylinder 24, the rack 25, the screw 26, the fingers 27.

The device works as follows.

5 Cassette. 12, with a stack of blanks laid on it, is mounted on a mobile platform 11 with fixation on the fingers 27. The racks 25 of the cassette 12 are shifted and set along the contour of the foot of the blanks. Mobile

The platform 11 by the pneumatic cylinder 13 is mounted along the base 1, the stack of blanks is installed above the lifting table 9. The grippers 18 with screw shafts 15 and 17 are mounted in the stop along the contour of the blanks. The receiving table 21 along the guides 22 moves up to the stop with the toy 25 and is fixed with screws 26. The pneumatic cylinder 24 by the gate 14 moves 20 one workpiece to the receiving table 21, while the lifting table 9 with the foot 23 rises under the action of the pneumatic cylinder 6 through the lever 3 on the TOJ - the thickness of the workpiece, and the pneumatic 25 cylinder 6 under the action of the link 10 of the lever 3 moves in the direction of the axis of rotation of the lever, thereby reducing the force on the rod 8 by an amount equal to the mass of the removed workpiece. After

30 removing the last blank, the lifting table 9 is lowered and the mobile platform 11 is moved to the second extreme position, thereby setting the second cassette to the working position.

35 Then the process is repeated.
