DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finger external setup device used for taking out and setting up a feed bar and fingers together with a mold in a transfer press during mold exchange.

[0002]

2. Description of the Related Art In a conventional cam drive press, a shift actuator is required in a feed bar in order to move a finger on a residual feed bar to a position above a take-out feed bar. In addition, it is necessary to turn the finger at the destination in order to avoid collision between the fingers. For this purpose, a dedicated turning device is provided on the feed bar or, as another method, the finger is automatically raised by a shift operation. In this case, there is a need for a method of avoiding interference by providing the guide device described above and standing up when the finger reaches an adjacent step.

On the other hand, in a transfer press using a servo motor as a drive source, a shift operation for moving to a feed bar receiving table utilizes a servo operation of a feed shaft, and collision between fingers is avoided by using the shifted fingers on a receiving side. There has been proposed a system for turning upright by a turning device provided in the system.

[0004]

In a cam-driven press, a shift device and a turning device are required for the feed bar itself. As a result, the weight of the movable movable portion is increased, and the piping and wiring are complicated.

[0005] When the shift device is built in the feed bar, an elongated hole for the shift stroke is required on the upper surface of the feed bar, and the rigidity of the feed bar deteriorates.

Since the shift device is necessary for the feed bar on the take-out side, it is necessary to provide the same number of devices as the number of front and rear bogies, that is, twice, so that the cost increases.

[0007] Even in the system already proposed for the servo drive press, the turning device is required on the bogie side, so the cost is high as above.

The present invention solves the above-mentioned problems, and eliminates the need to incorporate a shift device and a turning device into the feed bar itself, and does not require a turning device on the bogie side. An object of the present invention is to provide a finger external setup device in a transfer press, which can be simplified and can simplify piping and wiring.

SUMMARY OF THE INVENTION According to the present invention, there is provided a finger external setup device which extends a pair of right and left uprights in the front-rear direction and which remains in a take-out side feed bar taken out of a press body and a press body.

In the finger external setup device according to the present invention, the feed bar is located at a fixed position for the feed operation, the attachment is removed from the residual side feed bar, and the attachment is supported by the bogie, so that the attachment is removed together with the take-out side feed bar. The attachment is taken out of the press body by the cart. Therefore, since the shift mechanism is not built into the feed bar body, the weight and simplification of the feed bar can be achieved, so that the load on the drive unit is reduced and the motor capacity is reduced. As described above, there is no opening hole in the feed bar, the rigidity does not decrease, and the vibration of the feed bar during operation can be suppressed. In addition, since a device for turning the attachment on the feed bar receiving stand is not required, the bogie side can be simplified because there is no piping and wiring required when the turning device is provided on the truck side.

Further, a vertical fitting hole is provided in the attachment, and the mounting means is provided upright on the upper surface of the residual feed bar, and is fitted into the fitting hole so as to make the vertical movement of the attachment white. And a lock mechanism that locks the attachment to the residual side feed bar in an unlocked white space so as to restrain the vertical movement of the attachment, wherein the support means is fixed to the attachment and is fixed in the left-right direction. A supported member having an extended rod hole, and fitted to the rod hole of the supported member in a state in which the carriage is provided in a laterally movable white space and the feed bar is located at a fixed position for the lift operation and the feed operation. It is possible to insert and remove the locate pin with respect to the left and right direction that is inserted, and the supported member is supported by the support rod. It is possible to equity. Therefore, the feed bar can easily remove the plate from the residual side feed bar, and can easily support the plate on the carriage, so that the feed bar can be easily replaced.

Thereby, the first feed bar 51 and the second feed bar 52 are divided. The amount of movement at this time is set to an amount slightly larger than the amount by which the uneven fitting of the feed bar 12 can be released as the divided movement amount. In this state, the second feed bar 52
Is located in the middle of the rear upright 13 and the central upright 14, and is located at an optimum position for taking out.

Subsequently, as shown in FIG. 10 (h), when the first and second feed bars 51 and 52 are left as they are and the third to fifth feed bars 53 to 55 are advanced by the divided movement amount, Second feed bar 52 and third feed bar 53
Is divided.

Subsequently, as shown in FIG. 10 (i), the first and third feed bars 51 to 53 are kept as they are, and the fourth and fifth feed bars 54 and 55 are advanced by the divided movement amount. Then, the third feed bar 53 and the fourth feed bar 54 are divided, and the fourth feed bar 54 is
It is positioned at the take-out position in the middle of 14 and the front upright 15.

Finally, as shown in FIG.
The fifth feed bar 55 is moved forward by the amount of divisional movement while leaving the fourth to fourth feed bars 51 to 54 as they are. The fourth feed bar 54 and the fifth feed bar 55 are divided, and the fifth feed bar 55 reaches a limit of the feed operation.

In the above state, the second feed bar 52 may be taken out by the rear bogie 16 and the fourth feed bar 54 may be taken out by the front bogie 17. The second feed bar 52 is accompanied by a third attachment 63 attached to the third feed bar 53 together with the first and second attachments 61 and 62, and the fourth feed bar 54 has fourth to sixth attachments. Along with 64 to 66, a seventh attachment 67 attached to the fifth feed bar 55 is accompanied.

The above procedure may be reversed in order to bring the taken out feed bar 12 into the press body 11 and combine the feed bar 12 again. In particular, when attaching the carried third attachment 63 to the third feed bar 53, the third attachment 63 is required.
The third feed bar 53 is inserted below the attachment 63, the feed bar 12 is raised, the locate pin 81 is fitted into the fitting hole 87, and the third attachment 63 is locked by the lock mechanism.
Can be easily mounted as well as removed. The same applies to the seventh attachment 67.
