INDUSTRIAL APPLICABILITY The present invention can be applied to, for example, a transfer device in which a square motion mechanism is integrally incorporated in a bolster that is detachably attached to a press device.

[Prior Art] Conventionally, in a machining factory or the like, a transfer device for automatically sequentially feeding a work in the X direction has been known. This transfer device generally includes a frame 901 having a work transfer path 900 extending in the X direction and a work transfer path 900 arranged along the work transfer path 900, as shown in FIG. And a square motion mechanism 902 which intermittently transfers the X direction.

The square motion mechanism 902 is a drive-side mechanism 90 arranged on one end side in the X direction, that is, on the starting end side of the work transfer.
3, a driven-side mechanism 904 disposed on the other end side in the X direction, that is, on the end side of the work transfer, and a beam-shaped synchronizing mechanism 905 that connects the drive-side mechanism 903 and the driven-side mechanism 904 to synchronize them. Is formed by. Here, the drive side mechanism 903 includes an X-direction drive source. The beam-shaped synchronizing mechanism 905 is square-moved in the vertical direction along the X direction by the X-direction drive source. Here, the synchronizing mechanism 905 includes a transfer claw 906 for gripping the work. Then, when the synchro mechanism 905 is square-moved in the vertical direction, the work held by the transfer claw 906 is sequentially forwarded one pitch at a time along the X direction in the work transfer path 900, and is fed one pitch. It is processed in each process.

[Problems to be Solved by the Invention] In the transfer device described above, as described above, the square motion mechanism 902 has the drive-side mechanism 903 disposed on one end side in the X direction, that is, on the start end side of the workpiece transfer.

3 and the driven side mechanism 904 are synchronized with each other.
The reference numeral 5 is a structure that is installed in the X direction, which is the direction in which the workpieces are sequentially fed. Therefore, when the number of steps for processing the work increases, the length of the work transfer passage 900 naturally increases, and thus the length of the synchro mechanism 905 also increases. In addition, when the beam-shaped synchro mechanism 905 becomes long, the beam-shaped synchro mechanism 905 has to have high strength and high rigidity in order to prevent the beam-shaped synchro mechanism 905 from being bent. To increase. Therefore, in the conventional transfer device, when the number of steps increases, the inertial force when the beam-shaped synchronizing mechanism 905 makes a square motion tends to increase. The reason is that the synchronization mechanism 905 that synchronizes the drive side mechanism 903 and the driven side mechanism 904 is
This is because the work is installed along the X direction, which is the direction in which the workpieces are sequentially fed.

When 2 moves in the direction of arrow Y2, as described above,
The link plate 74 and the link pin 71 of the synchronizing mechanism 7 shown in the figure move in the direction of the arrow Y2, and as a result, as is apparent from FIG.
It swings in the direction of arrow P2 around the center. Therefore, the first
As shown in FIG. 5, the synchronous shaft 78 operates in the axial direction thereof, that is, the direction of the arrow M2, the link plate 77 on the driven side swings around the link pin 76 in the direction of the arrow N2, and the link pin 692a on the driven side. , The link drive shaft 692 is the 15th
It moves in the direction of arrow Y2 shown in the figure. As a result, the driven claw group 3 on the driven side opens in the arrow Y2 direction. That is, the drive side transfer claw group 2 and the driven side transfer claw group 3 are opened. As a result, the transfer claw 2
1, 31 release the crushed work W1, and the first transfer claws 22, 3
2 separates the waste forged product W2, and the second transfer claws 23, 33 separate the finished forged product W3. As a result, the crushed work W1, the rough forged product W2, and the finish forged product W3 are advanced by the P pitch (that is, the stroke length of the pneumatic cylinder 53 for conveying in the X direction),
It is intermittently transferred to the next process.

When the press device A is driven in this manner, the crushing upper mold 184, the rough ground mold 185, and the finishing mold 18 are again driven.
6. The deburring upper die 187 moves downward, the crushed work W1 becomes the rough forged product W2, the rough forged product W2 becomes the finished forged product W3, and the finished forged product W3 is deburred.

When the deburring process is performed, when the driving side transfer claw group 2 and the driven side transfer claw group 3 move in the direction of the arrow X1 as described above, the clamp die 81 as shown in FIG.
The clamping surface 82 of the above is away from the deburring lower mold 177. In such a state of being distant from each other, the finish-forged finished forged product W3 is nipped and transferred by the second transfer claw 23 of the drive side transfer claw group 2 and the second transfer claw 33 of the driven side transfer claw group 3. As a result, the finish forged product W3 is set in the cavity of the flash lowering die 177. After being set, the drive side transfer claw group 2 and the driven side transfer claw group 3 are indicated by the arrow X.
Since it retreats in two directions, the clamp die 81 that interlocks with the driving-side transfer claw group 2 and the driven-side transfer claw group 3 has a T shape shown in FIG.
Direction, and as a result, the clamp surface 82 of the clamp die 81 contacts the peripheral wall surface of the finished forged product W3. As a result, as shown in FIG. 17, the finished forged product W3 has the clamp die 8
The clamp surface 82 of No. 1 and the cavity die surface of the flash lowering die 177 are clamped. Since the deburring upper die 187 descends in the clamped state as described above, the central hole W30 of the finish forged product W3 is deburred, and after deburring, the
As shown in the figure, the clamp die 81 moves in the direction opposite to the arrow T direction, the clamp die 81 moves away from the flash pulling die 177, and the sweepers 24 and 34 move forward in the arrow X1 direction. Finished forged product W
The burrs 3 are extruded from the flash lowering die 177, while the burrs separated from the finish forged product W3 are dropped onto the chute 825 through the guide holes 177a.

By the way, there are many kinds of works when performing multi-product production. Therefore, many types of bolster bodies 1 dedicated to the work are prepared according to the type of the work. When the type of work is changed, the attachment hole 10 shown in FIG.
The bolt inserted through a is removed, and the bolster body 1 is removed from the bolster mounting portion A100 of the press device A. Then, the drive-side mechanism 5 and the driven-side mechanism 6 of the square motion mechanism 4 which constitute the transfer are also automatically removed from the press device A.

Then, a new drive-side bolster unit 10 and another driven-side bolster unit 14 dedicated to another work are attached to the bolster mounting portion A100 of the press device A. When scooping, the drive side mechanism 5 and the driven side mechanism 6 which constitute the square motion mechanism 4 dedicated to the work are automatically attached. After all, when the bolster body 1 is replaced, the square motion mechanism 4 that constitutes the transfer is automatically replaced. After the replacement, the press machine is driven to perform the press forming process, and another work is forged.

(Effects of Embodiment) In this embodiment, as shown in FIGS. 1 and 2, the drive side mechanism 5 is provided on one end side in the Y direction which is a direction intersecting with the transfer direction (X direction) of the work W. , A driven side mechanism 6 is provided on the other end side in the Y direction, and a movable base 522 as an X direction synchronizing mechanism further includes a drive side mechanism 5 and a driven side mechanism 6.
And the synchronous shaft 78, which is a main component of the Y-direction synchronizing mechanism 7, is mounted in the Y-direction to connect the drive-side mechanism 5 and the drive-side mechanism 5.
And the driven side mechanism 6 are connected to each other in the Y direction.

Therefore, even when the number of steps for forging and pressing the work is increased and the length of the work transport ridge 17a in the X direction is increased, the length of the movable table 522 in the Y direction and the length of the synchronous shaft 78 in the Y direction are increased. Basically, it does not need to be changed. Therefore, even when the process of forging and pressing the work increases and the length of the work transfer passage 17a becomes long, the movable table 522 as the X-direction synchronizing mechanism and the synchronization shaft 78 as the Y-direction synchronizing mechanism 7 are provided. The weight of is basically unchanged. Therefore, in the present embodiment, it is advantageous to reduce the inertial mass of the movable table 522 and the inertial mass of the synchronizing shaft 78, and thus it is advantageous to reduce the inertial force during the square motion. Moreover, in this embodiment, many parts of the square motion mechanism 4 are formed of an aluminum alloy, which is advantageous for further reducing the inertial mass and the inertial force during the square motion.

Further, in this embodiment, when the bolster body 1 is replaced, the square motion mechanism 4 that constitutes the transfer is automatically replaced. Therefore, the labor for replacing only the transfer is not required, the replacement work is facilitated, and the multi-product production is facilitated. It is advantageous.

Further, in this embodiment, since the square motion mechanism 4 constituting the transfer is incorporated in the bolster body 1, the transfer foundation may be unnecessary.

[Other Embodiments] The above-described embodiment is applied to a bolster device detachably attached to a forging press device, but is not limited to this, and is applied to a bolster device used in a sheet metal pressing process, a deep drawing process, or the like. Of course, it is okay.

In addition, the transfer device according to the present invention is not limited to the embodiment described above and shown in the drawings,
For example, it may have a three-dimensional transport function, and it goes without saying that it can be appropriately modified and implemented within a range not departing from the gist.

[Advantages of the Invention] The transfer device according to the present invention has an X-direction synchronizing mechanism, and a Y-direction synchronizing mechanism is a workpiece transfer direction X.
It is a configuration that is installed in the Y direction that is orthogonal to the direction. Therefore, even if the number of steps for processing the work increases and the length of the work transfer path in the X direction becomes longer, the lengths of the X-direction synchro mechanism and the Y-direction synchro mechanism are basically changed. It is not necessary to do so, so the X-direction synchro mechanism,
The weight of the Y-direction synchronizing mechanism is basically unchanged. Therefore, it is advantageous to reduce the inertial force during the square motion.
