(5) DEVICE FOR REMOVING OF STRAWED PARTS FROM THE PRESS WORK AREA

one

The invention relates to the mechanization and automation of stamping production and can be used to remove stamped parts from the working area of a press.

A device for removing stamped parts from a working area of a press is known, comprising upper and lower punch plates, a receiving tray, jg mounted on flexible elements with the possibility of reciprocating movement, a counterweight connected to one side of the tray, the drive of moving the tray is

The disadvantage of this device is that at the time of loading the workpiece, the flexible receiving tray with the stamped part is in the working area, which makes it difficult for the workpiece to be unloaded from the working area, especially at low speeds, to the press.

The purpose of the invention is to improve the conditions for unloading blanks from the working area of the press by freeing the working area before the press ram moves down.

The goal is achieved by the fact that the device containing the lower plates, the receiving tray mounted on the flexible elements with the possibility of reciprocating movement, the counterweight connected to one side of the tray, the movement drive, is equipped with a mechanism for disengaging the drive of the tray made in hard disk connected with a tray of strips located in the plane of the tray, guides with protrusions mounted on the bottom plate, placed in guide carriages with hingedly mounted dogs, interacting alone The ends with rigid strips of the tray and the other with protrusions of the guides, an additional counterweight connected to one side of the carriages whose opposite side is connected through an additional flexible element to the upper plate. Figure 1 shows the device in isometry; in FIG. 2, that is heh, when the slider is applied at the upper dead center; figure 3 - the same, in the lowest position; in fig. - the same, at the moment when the slider is below the upper dead center per mm in the course of the slider up; Fig. 5 is a disconnection mechanism; Fig. 6 is a section IA-A in Fig. 5. A JcocTOMT device from a flexible P | rim tray 1 made in the form of a conveyor belt mounted for reciprocating movement on rotatable supports 2 and 3 placed on a press table. . The rear part of the flexible receiving tray 1 is connected by flexible links 5 to the counterweight 6. To the flexible receiving tray 1, slats 7 are secured with the ability to move in the guide grooves 8 of the disconnection mechanisms 9. The slats 7 have axles 10, on which the rollers 11 are fixed with the possibility of movement along the housings 12 of the disengagement mechanisms 9. Rollers 11 are made of bearings. The disconnection mechanisms 9 are mounted on the press table on the sides of the punch and consist of a carriage 13 located in the housing 12, in the side walls of which the guide grooves 8 are made. In case 12, copier 1 | is located. The carriage 13 consists of two cheeks 1 fixed to the axles 16, on which the running rollers 17 are mounted so as to move in the slots of the housing 12. The running rollers 17 can be made in the form of bearings or rollers. Between the brushes 15 on the axis 18 a hinged pawl 19 is installed with the possibility of its upper part interacting with the slats 7 of the flexible receptacle. Tray 1 and the lower part - with a copier The carriage 13 is connected on one side with a flexible link 20 with a counterweight 2 on the other hand with a flexible link 22 with a transfer mechanism 23 mounted on the press table and consisting of a block of two pulleys 24 and 25. The required gear ratio is provided by the ratio the diameters of the pulleys 2k and 25. The pulley 25 is connected via a flexible link 26 to the slider of the press-sa 27. The device operates as follows. At the beginning of work, when the press slide 27 is in the upper extreme position, the flexible receiving tray 1 is under the action of the counterweight 6 in the lowest left position, the working area of the press is free. The flexible links 26 are wound up from the pulleys 25, and the flexible links 22 are wound on the pulleys 24, as a result of which the carriage 13 is in its extreme position. After loading the preform in the die and turning it on to the press, the slide of the press 27 moves down. The carriage 13 under the action of counterweights 21 move ;;; to the extreme left position, unwinding the flexible links 22 from the pulleys 24 and winding the flexible links 26 onto the pulleys 25. The dogs 19 slide off the copier 14 and, under the effect of a greater weight of the lower left part, turn and take the raised position. The dogs 19 approach the flexible receiving tray 1, are deflected to the right by the action of the bars 7, and, by the way of the bar 7, are returned to a raised position at the lowest position of the slider. As the press ram 27 moves upward, the flexible links 26 are wound up from the pulleys 25, and the flexible links 22 are wound on the pulleys 24. The carriages 13 move to the right, ensuring that the strips 7 of the receiving tray 1 are gripped by the pawl 19 by moving the flexible receiving tray 1 to the working area of the press. At that moment, when the slide of the press 27 does not reach the top dead center of 30-40 mm, the stamped part is reset to the flexible receiving tray 1. With the further movement of the slide of the press 27 upward, the carriage 13 moves further to the extreme right. Dogs 19 in their lower part run over the copier 14, the dog 19 is turned to the right and pressed against the surface of the strip 7, as a result of which the dogs 19 are disengaged

with a strap 7 flexible receiving tray 1.

Under the action of the counterweight 6 are flexible receiving tray 1 is moved from the working area of the press. The strips 7 are shifted in the direction of the slots 8 of the mechanism E of the disconnection, supported by the rollers 11 on the side surfaces of the housing 12.

 19, under the action of his own, the yugoslav returns to the raised position.

 Ik) vratsahtschims supports 2 and 3, the flexible receiving tray 1 moves to the shortest left position and removes the stamped part from the working area of the press to the basket or to the container ...

At the moment when the press ram 2 7 comes to top breakage, the working area of the press is free from the flexible receiving tray 1.

Then the cycle repeats.
