00 -vj el The invention relates to the mechanization of metal forming. The closest to the proposed technical essence and the achieved effect is a device for removing parts from the working area of the press, containing a tray, an emphasis with a cushioning pad fixed at the end of the tray and driven from the press slider assembly lifting parts 1. The disadvantage of the known device is limited functionality . The purpose of the invention is to expand the functionality of the device by increasing the range of adjustments of the height of the lifting parts. The goal is achieved by the fact that in the device for removing parts with an extended short axis of the working area of the press, containing a tray, an emphasis with a shock-absorbing gasket, fixed at the end of the tray and driven from the press ram, the lifting part assembly, the lifting part assembly with grippers for parts, and the drive of the chain conveyor is made in the form of a copy, attached to the press slider with the possibility of adjusting movement, a bracket with a deflection sprocket and an adjustable stop, heated on the bed of the press, swivel arm with a roller at the end mounted on the brace with the ability to interact with the roller with a copier, a chain segment, one end of which is connected with the rotary lever and the other with a load, while the chain segment is placed with the possibility of coverage deflecting stars. daughters and sprocket chain conveyor. FIG. 1 shows the proposed device, side view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3. The device contains a chain conveyor, rigidly fixed, by means of frame 1 on beams 2. On frame 1 of chain conveyor, drive 3 and deflecting 4 shafts with asterisks are fixed, on which chain contours 5 are mounted with 6 grips fixed to them by cross-arms 7. the frame 1 of the chain conveyor is also fixed to the chute 8 for receiving parts 9 from the tray 10 fixed on the press table 1 1 and beams 2. On the press table II the bracket 12 of the chain hoist drive is fixed, in which the lever 13 is fixed by means of the axis 14 with Opportunity to turn: relative to the latter. At the other end of the lever 13, provided with a roller .15, is fixed the end of a length of chain 16, which cooperates with output 17 sprockets and deflecting 18 shafts mounted in a housing. At the second end of the chain 16, a weight 19 is fixed with the possibility of movement in the vertical direction. An adjustable stop 20 is also installed on the case. The output shaft 17 is connected to the drive shaft 3 of the chain conveyor by means of an overrunning clutch containing a half coupling 21 fixedly mounted on the shaft 17, and the case 22 coupled to the ball 3 with the possibility of transmitting torque. On the bracket 12 is mounted a latch 23 with a spring-loaded roller, interacting with the body 22 overrunning clutch. The press slider is rigidly fixed with the possibility of adjustment in the vertical direction and the possibility of contact with the roller 15 by the copier 24. On the beams 25, an emphasis 26 for the product 9 is mounted. The device works as follows. As the press 27 moves downward, the copier 24 contacts the roller 15 and, lowering it, rotates the lever 13. The chain 16 attached to the lever moves 16, rotating the output shaft 17 and the drive shaft 3 of the chain conveyor. The grippers 7 of the latter, displaced, and together with the chain contours, lift part 9 (stamped in the previous cycle and placed on the groove 8, pass along tray 10 up to the stop 26) and drop it onto the storage bin of the hopper or into the container. During the working stroke of the press slide, the lever 13 rotates to a certain angle while the roller 15 moves along the lower inclined working surface of the copier 24. As the slide is further lowered, the roller 15 descends on the vertical working surface of the copier and turn the lever, and therefore the movement of the chain hoist stops, although the slider continues to move down. At the end of the stroke of the lever 13, the overrunning clutch housing 22 is fixed relative to the fixed bracket 12 and holds the drive shaft 3 of the chain hoist stationary. When the slide moves back (idle) after the roller 15 has moved to the lower inclined surface of the copier 24, the lever 13 is rotated around the axis 14 until it stops 20, while the chain conveyor remains stationary due to the overrunning clutch and the specified lock. The stroke of the press slide used to unload the stamped part depends on the length of the lever 13, and the fine adjustment of the stroke of the chain hoist is performed by the stop 20, while the lower position of the lever 13 remains constant. The portion of the stroke of the slide is used (initial, average, or final) depending on the installation of copier 24 (higher or lower). The slope of the lower working surface of the copier improves the dynamics of the device. Conveyor stepper drive with grippers for receiving parts from the tray and lifting them and delivering them to the receiving tray by

the drive from the slide of a periodic synchronous action allows you to simplify the drive of lifting products, eliminate additional energy carrier for this and synchronize the lifting of parts with the working stroke of the slide with a simultaneous significant increase in reliability and stability of the device.
