00 00 The invention relates to the processing of metals by pressure, in particular to devices for loading and moving the workpieces between the stamping positions. A device for loading and moving workpieces between punch positions is known, comprising a conveyor, a piece-by-piece mechanism for transferring workpieces from a conveyor to a stamp, and a gripping element for moving the workpiece relative to the punch positions, installed with reciprocating interoperative movement over a stamp from a Cl drive. the complexity of its design, which leads to reduced reliability. The goal is invented and - increasing the reliability of the device. The goal is achieved by the fact that in the device for loading and moving workpieces between the positions of a stamp containing a conveyor, a mechanism for issuing workpieces from a conveyor to a stamp and a gripping element for moving workpieces relative to the positions of a stamp, installed with the possibility of reciprocating interoperational movement over the stamp from the drive, the mechanism for the piece delivery of blanks and the gripping element are combined into one unit, made in the form of a rigid pusher and a fish hinged on it Aha, pivotally mounted relative to the pusher. Figure 1 shows the proposed device, a General view; in Fig.2, section A-A in Fig.1i in Fig.Z is the time of the blank; Fig. 3 shows the feed of the workpiece by the pusher to the right stream in Fig. 3 — the gripping elements in the initial position, next to the workpiece in the initial position of the guide tray; Figure 6 shows the moment when the pusher feeds the workpiece to the straightening creek; Fig. 7 shows the position of the workpiece in the guide pan in the straightening and embossing streams of the stamp; Fig. 8 shows the feeding of the blanks into the straightening stream, transferring the straightened workpiece from the finishing to the embossing brook and removing the finished parts from the working area of the stamp. The device complex can be used, for example, on a scale for dressing and chasing articles and contains a press hammer 1, conveyor 2, conveyor 3 of finished products, container 4 and control panel 5. The conveyor 2 has a guide chute 6, a mechanism 7 for issuing blanks by piece and a rammer 8. On the latter, a pusher 9 is mounted, on which the lever 10 is hinged, the guide tray 6 is provided with a sensor 11 for the presence of the blank. Dump 8 has sensors 12 and 13 extreme positions. On the conveyor 2 is a remote control 5 controls. The stamp 14 of the press hammer 1 has a straightening brook 15 located above the horizon of the embossing brook 16. On the frame of the press hammer 1 there is a sensor 17 of the beginning of the cycle. Conveyor 2 has a toothed comb 18 connected by an eccentric shaft 19, above which is a double track chute 20. The complex works as follows. From the console 5, the conveyor 2 and the conveyor 3 finished products are started up. The blanks 21 are loaded into the conveyor 2, where they accumulate and move to the press 1. If at the initial moment there are no blanks in the guide tray 6, then the remote control 5 switches on the mechanism 7 of the piece workpiece, with the CONDITION that the dossier 8 is in the original ( extreme rear position (FIG. 3). As soon as the workpiece arrives at the initial position of the tray 6, the sensor 11 for the presence of the workpiece gives the command to switch on the filling device 8 and to return the mechanism 7 of the piece output to the original position. The ejector pusher 9 feeds the workpiece into the straightening creek 15. punch 14 (FIG. 4), presses the extreme front position sensor 12, which gives a signal to return the dostator 8 to the rearmost position, while the dossator 8 presses the rear posterior sensor 13 5 I give the 1st command to the work of the press hammer 1. For this team, the work of the press hammer 1 is performed up and down. In the extreme position, the press hammer slider 1 presses the start sensor 17 of the cycle. The cycle repeats: the lever 10 when the docator 8 moves forward (FIG. B captures the straightened workpiece from the straightening brook 15 and transfers it to the embossing brook 16 (6) simultaneously with the loading of the plunger 9 of the straightening brook 15. When the rammer 8 returns to the original rear The position of the lever 10 rotates around the horizontal axis of the hinge and passes over the workpiece lying in the stream 15 of the stamp 14 (Fig. 7).

In the next cycle, when loading the billet into the straightening creek 15, the lever 10 captures the extracted billet, moves it to the embossing creek 16, and the piece is ready at the same time from the embossing creek 16 is pushed out by the etched billet onto the conveyor 3 (Fig. 8).

The proposed device in comparison with the known possesses increased reliability of operation.
