The invention relates to press constructions, more specifically to the design of devices for fastening dies on presses.
The purpose of the invention is to increase the service life and reliability.
FIG. 1-5 schematically shows the stages of changing and clamping a package of a stamp in a press; in fig. 6 - a stamp package with additional plates clamped on the lower clamping plate of the press: the clamping clamping plate being located in the T-slot of the upper clamping plate; in fig. 7, side view |. 8 - top of the press plate with a fixing clamping bar in the retracted, but not fixed position, longitudinal section; Fig. 9 shows the upper clamping plate of the press with the fixing clamping plate in the fixed and clamped positions, longitudinal section; in fig. 10 is a section A-A in FIG. eight; FIG. 11 is a section BB in FIG. 9; FIG. 12 — node I in FIG. 8; in fig. 13 - locking clamping plate, two upper clamping devices and one upper additional plate with two T-slots; Figs 14-16 are embodiments; in fig. 17-20 - option with a horizontally movable stamp package.
The stamp package, consisting of the lower half 1 and installed above it with a gap of the upper half 2 of the stamp, of any overall height H by means of a removable trolley 3 is set at the level of the lower clamping plate 4 (Fig. 1-5). In an alternative embodiment, the package stamp 5 can be laid on the carrier pair 6 (Fig. 6). For this purpose, the pacot of the stamp 5 is laid on the carrier pair 6 by means of a crane or a forklift (not shown). Then, the package of the stamp 5 along the roller conveyor 7, which is located both on the carrier pair 6 and on the lower clamping plate 4, moves until it adjoins the stop 8, provided with an approximation switch 9. The carrier pair 6 is removably suspended on the lower clamping plate 4.
Upper 2 and lower 1 half of the stamp are equipped with one additional plate 10 (11), respectively. On additional plates 10 and 11, a stamp and tooling can be preassembled outside the press. Dey0

The lower clamping plate 4, which acts as a press slider, for example, a precision notch press, is at its bottom dead center. This means that the overall dimension, counting from the floor, always remains constant even at different heights of the N punch.
In FIG. 6, the lower half of the 1 punch with its lower additional plate 11 is shown in a state already clamped on the lower clamping plate 4. This is due to the fact that the clamping strips 12, which are fixed below on the lower additional plate 11, are inserted into the corresponding T-shaped grooves 13 of the lower clamping plate 4 and secured by four, four clamping devices 14 provided in the lower clamping plate 4. Clamping the action of them; the clamping devices 14 are triggered by the actuation of the proximity switch 9 in the stop 8, when the inserted packet of the stamp 5 comes to rest with this approximation switch 9. The clamping reinforcement is transmitted through the clamping strips 12 to the lower additional plate 11 or the lower half of the 1 punch.
Both in the clamping plates 15 and 4, and in the upper half of the 2 punch and lower half of the 1 punch, or in the additional plates fixed on these elements 10 and 11, there are respectively two parallel T-shaped grooves 13 and 16. In each clamping plate 15 and 4 four clamping devices 14 are placed, which are also equipped with T-shaped grooves 17, T-shaped grooves 17 of clamping devices 14 are coaxial with T-shaped grooves 13 of clamping plates 15 and 4. Built-in clamping plates 15 and 4 clamping devices 14 can be hydraulic or mechanical devices hell or gidrom khanicheskogo action,
In the T-shaped grooves 13 of the upper clamping plate 15 and the T-shaped grooves 17 of the upper clamping device 14, two locking clamping bars 18 are arranged to move, respectively, with mutually distant cams 19. At one end, the fixing clamping bars 18 are connected to the driving devices 20 by means of which they are moved from one extreme position to another. Driving devices 20 mo

They are hydraulic, pneumatic, electrical or mechanical actuators.
When lifting the bottom acting. As a press slider, the clamping plate 4 with the stamp package 5, the fixing clamp strips 18 are in the position shown in FIG. 6. When the upper additional plate 10 abuts against the upper clamping plate 15, the switch 21 is touched to approach the upper clamping plate 15 (Fig. 7), for which the actuator 20 operates. The cams 19, which in this first extreme position of the locking the clamping strips 18 are immersed in two recesses 22 of the T-shaped grooves 16 of the upper additional plate 10, moved as a result of the movement of the strips 18 by the driving devices 20 to the second position, in which they engage in the T-shaped grooves 16 of the upper additional plate Litas 10. Now the upper additional slab 10 is started to be made with the upper half 2 of the stamps by the upper digging devices 14.
FIG. 8 and 10 a locking clamping strip 18 is shown in the indentation

volume, unfixed position, but before the start of clamping by upper clamping devices 14, FIG. 9 and 11 depict a locking clamping plank 18 in a fixed and clamped position in the upper clamping plate 15. A slight height offset of the fixing clamping strip 18 relative to the firmly mounted drive device 20 when clamping allows the fitting part 23 to be carried out (FIG. , 12), End control 2
.dl of both extreme positions of the fixing clamping bars 18 is shown in FIG. 8.
Depending on the type of press, the upper clamping plate 15 may also function as a press slide. In this case, the locking clamping strips 18 are also embedded in the grooves 13 of the upper clamping plate 15. In low-power presses, instead of respectively two two grooves 13 in the clamping plates 15 and 4, and instead of the two locking clamping strips 18, one or one of them.

FIG. 14 schematically shows a form in which the upper clamping devices 14 are embedded in the upper clamping plate 15 of the press, the fixing clamping strip 18 with two cams 19 with the corresponding drive device 20 being placed with the possibility of movement in the T-shaped groove 16 of the upper half 2 of the stamp -shaped groove 13, as well as recesses 22 into which the cams 19 are inserted, are also provided for the upper clamping plate 15,
The form of the embodiment according to FIG. 15 is similar to the embodiment according to FIG. 14. with the exception of the upper clamping devices 14, which are not embedded in the upper clamping plate 15, but in the upper half 2 of the stamp,
According to FIG. 16 a locking clamping bar 18 with cams 19 is placed in a groove 13 of the upper clamping plate 15. It moves in this groove 13 5 by means of a driving device 20. The upper clamping devices 14, as well as a T-shaped groove 16 with recesses 22, into which The cams 19 are provided in this case in the upper half of the fault 2 stamps.
Fig. 17-20 schematically depicts a variant in which the fixing and clamping devices (cams 19) are fixedly placed either in the T-slot 13 of the upper clamping plate 15 or in the T-slot 16 of the upper half 2 of the stamp. At the same time, the package of the stamp 5 moves in the horizontal direction so that the cams 19 inserted into the recesses 22 can slide into the groove 13 or 16, after which the upper half of the package of the stamp 5 is clamped on the upper clamping plate-15.

In the event of a malfunction in the mechanism for moving or clamping the press, the die can be removed under any circumstances, since the locking and clamping devices or mobile bars with their actuating devices are quite accessible; this eliminates the need to destroy the punch. At the same time, the possibility of clamping dies of any height without prior adjustment of the press is created. Reduced period of change compared with other known systems
