Abstract

The invention relates to the processing of metals by pressure. The purpose of the invention is to reduce the time for changing a stamp. The carriage 13, by means of fixing elements, separates the module 4 from the die 3, during movement the module 4 rests on the sub-die plate and the table 11 by the carriage 19, the module 4 moves to the table 17. Then the carriage 13 moves the stamp and the magazine 22. Next, the shop 22 with two dies moves to the other extreme position and. the above-described operations occur in the reverse order, and as a result, their duplicate stamp 3 is inserted into the press 1 of 3 p.

Description

The invention relates to the processing of metals by pressure, in particular to devices for changing dies on presses.

The purpose of the invention is to reduce the time for changing a stamp.

Fig 1 shows a device for changing dies in Fig 2 - the same, in plan; Fig 3 is a section A-A in Fig 1; figure 4 - section bb figure 1

The press 1 is equipped with a substamp plate 2 on which a stamp 3 is installed. Stamp elements requiring flexible external connections are mounted on a detachable auxiliary module 4, such elements include, for example, pneumatic actuator 5 of movable puller 6, pneumatic actuator 7 of movable device for lubrication and cooling 8 and position sensors (not shown in the figures) Flexible external connections of these elements (flexible hoses for supplying compressed air, water, lubricant and flexible electrical wire), as well as

the places of their joints with these elements (not shown in the figures). The module and stamp 3 have a common basis. On the sub-die plate 2, there are side stops 9 of the stamp. At the base of the stamp 3 there are transport holes a, and in the base of module 4 there is a transport hole b for longitudinal movement of module 4 and transport holes for transverse movement of module 4. The mechanism for changing dies 10 contains an intermediate table 11 on which cantilevers are installed in guides 12 the carriage 13 is extended in the direction of the longitudinal axis of the press. The carriage 13 is moved by a hydraulic cylinder 14. The carriage is provided with vertically moving locks 15 made in the form of hydraulic cylinders. The distance E between the axes of the clamps 15 is equal to the distance between the axes of the holes and the stamp 3 The diameter of the latches 15 is made with the possibility of entering

Holes Stampa 3 m hole b module. On the table 11 is installed side guides 16 stamp.

The die changing mechanism 10 also contains an additional stationary table 17, on which in the guides 18 a carriage 19 is mounted cantilevered in a direction transverse to the longitudinal axis of the press. The carriage 19 is moved by a hydraulic cylinder 20. The carriage is equipped with vertically moving latches 21 similar to the latches 15. Distance The distance between the axes of the latches 21 is equal to the distance between the axes of the holes in the module 4. The diameter of the latches 21 is configured to be inserted into the holes in the block 4.

The magazine of stamps 2 is made with the possibility of movement in the direction transverse to the longitudinal axis of the press from the cylinder 23. The course of movement corresponds to the transverse dimension of the stamp. A duplicate stamp 3 is placed in the Store. (The store has side stamp guards 24 | stamp.

The device works as follows.

The carriage 13 moves forward by the amount of stroke EI. The latch 15 is inserted into the “b” hole of module 4, the carriage 13 returns to its original position and separates module 4 from the pitch - 3 by the stroke fi. The latch 15 is removed from the hole b. At the time of movement, the module 4 is supported on the under-stamp plate 2 and the table 11. / The carriage 19 is then moved forward to the movement h. The tabs 21 are inserted into the hole in module 4. The carriage 1Ј returns to its original position and mod 4 is moved to table 17 (dashed line in Fig. 2). The flexible external connections of the elements of the module 4 allow the indicated displacements of the module to be performed without their segmentation. Next, module 13 moves forward to the zelchina of the turn. The latch 15 is inserted into the front hole a of the stamp 3. Next, the carriage 13 returns to its original position and the stamp moves by the amount of stroke D. In this case, the stamp rests on the sub plate 2 and the table 11. The clamp is removed from the hole of the stamp and the beam moves forward again by the magnitude of the stroke f. The tabs 15 are inserted into both holes of the stamp, the carriage 13 returns to its original position and the stamp moves to

stroke size f, placed on table 11 (dotted line in fig. 1), - Next, the retainers 15 are also again retracted from the die aperture, moving the bar 13 forward by the stroke size f. the introduction of the latch 15 in the rear hole a of the stamp 3, the return of the carriage 13 to its original position with the simultaneous movement of the stamp 3 on the stroke-f and removal

the latch 15 of the hole and. As a result of these actions, the stamp 3 is placed in the shop 22. Next, the shop 22 with two stamps 3 (extracted from the press and duplicating) moves - from the original to

other extreme position. Next, the above-described operations occur in reverse order, and as a result, the duplicate stamp 3 is installed in the press, module 4 is associated with the stamp. For accuracy
