Description

[Detailed Description of the Invention] This invention relates to a device for discharging punched members in press working.

Conventionally, when the bolsters, which are arranged on both sides of the press so that they can be moved in and out of the press and are equipped with punching tools, are sequentially carried into the press,
A punched member punched by the above punching tool,
The bolster is discharged in the direction of the waiting position, that is, the empty space created by the bolster being carried into the press device, but depending on the bolster used, the setup of the punched member discharge device may be different. The disadvantage was that it required a lot of time to change the setup. The object of this invention is to eliminate the above-mentioned conventional drawbacks and to provide a device that can automatically set the punching member discharge device by moving the bolster.

Embodiments of this invention will be described below with reference to the drawings.

In FIG. 1, 1 is a press device, 2a, 2
b, 2c, and 2d indicate the supports or fixed parts of the press device, and there are bolsters 3 and 4 on both sides of the press device 1.
is arranged so that it can be moved in and out of the press device 1.

The bolsters 3 and 4 are movable in the directions of arrows A and B in FIG. 1, and as shown in FIG. A through hole 5b is formed in the holding surface 5a of the holding member 5 in communication with the punched hole 6a of the lower mold 6, and openings 5d are formed in both side walls 5c.

A seesaw type chute 7 is provided inside the holding member 5, and discharge conveyors 8, 9 that operate in the directions of arrows C and D are provided on both sides of the bottom of the seesaw type chute 7.

The see-saw type chute 7 has a support shaft 10 fixed to the center thereof, and uses this support shaft 10 as a fulcrum and moves together with the support shaft 10 in the directions of arrows E and F to perform a see-saw movement. As is clear from FIG. 3, the support shaft 10 is rotatably supported by bearing members 11 at positions where both ends thereof protrude in the front-rear direction of the lower punching die 6 and the holding member 5. The projecting member 12 is attached to one end thereof in the vertical direction.

The protruding member 12 is attached to the guide member 1 as shown in FIG.
The roller 1 is inserted through a guide hole 13a formed vertically through the roller 1 and has a horizontal axis at its upper end.
4 is rotatably attached, and the protruding member 12
A spring 15 is stretched between the guide member 13 and the guide member 13. That is, a pin 13b protruding from the guide member 13 and a pin 12a protruding from the protruding member 12.
Both ends of the spring 15 are hooked to the spring 15, and the spring force of the spring 15 brings the protruding member 12 into contact with the position shown in FIG. 5a or 5b, that is, both ends of the guide hole 13a of the guide member 13. hold in position. In this case, the protruding member 12 moves from one end of the guide hole 13a to the other end of the guide hole 13a and from the other end to one end using the guide hole 13a of the guide member 13 as a guide. Accordingly, the seesaw type chute 7 performs seesaw motion.

When the bolster 3 is moved in the direction of arrow A from the position shown in FIG. 1 and is carried into the press device 1, and the protruding member 12 is in the state shown in FIG. 5a, the movement trajectory of the roller 14 attached to its upper end is A locking member 17 is attached to the support column 2a correspondingly. The locking member 17 is attached to the bolster 3 as shown in FIG. 6a.
A slope 17a is formed with a downward slope in the carrying direction. Further, when the bolster 4 is moved from the position shown in FIG. 1 in the direction of arrow B and is carried into the press device, and the protruding member 12 is in the state shown in FIG. 5b,
A locking member 18 is attached to the support column 2b in accordance with the locus of movement of the roller 14 attached to the upper end thereof, and the locking member 18 has a slope that slopes upward in the direction in which the bolster 4 is carried in, as shown in FIG. 6b. 18a. In the figure, 19 is a punching member storage pallet, 2
0 indicates the upper mold.

In the above configuration, when carrying the bolster 3 into the press apparatus 1 and making the lower die 6 for punching mounted on the bolster 3 correspond to the upper die 20 of the press apparatus 1, the bolster 3 is arranged as shown in FIG. It is moved in the direction of arrow A from the position shown, that is, the standby position. In this case, even if the protruding member 12 is in the state shown in FIG. 5a and the seesaw chute 7 is inclined to the state shown in FIG. By contacting the slope 17a and further moving the bolster 3 in the direction of arrow A, the protruding member 12 is rotated about the support shaft 10 against the spring force of the spring 15, and is displaced to the state shown in FIG. 5b. With this displacement, the see-saw chute 7 is caused to see-saw in the direction of arrow E, and is maintained in the inclined state as shown in FIG. 7b by the spring force of the spring 15.

By holding the seesaw type chute 7 in the state shown in FIG. It falls onto the seesaw type chute 7, slides on the upper surface of the chute 7, reaches the discharge conveyor 8, and is conveyed from this position in the direction of arrow C, where it is placed on standby before the bolster 3 is carried into the press machine 1. It is discharged and stored in a pallet 19 set in the direction of the position.

On the other hand, when carrying the bolster 4 into the press apparatus 1 and making the lower die 6 for punching mounted on the bolster 4 correspond to the upper die 20 of the press apparatus 1, the bolster 4 is placed in the standby position shown in FIG. Move from the position in the direction of arrow B. In this case, even if the protruding member 12 is in the state shown in FIG. 5b and the seesaw chute 7 is inclined in the state shown in FIG. By contacting the slope 18a and further moving the bolster 4 in the direction of the arrow, the protruding member 12 is moved by the spring 1.
It seesaws in the direction of arrow F against the spring force of 5, and maintains the inclined state as shown in FIG. 7a by the spring force of spring 15.

By holding the seesaw type chute 7 in the state shown in FIG. It falls onto the seesaw type chute 7, slides on the upper surface of the chute 7, reaches the discharge conveyor 9, and is conveyed from this position in the direction of arrow D, where it is placed on standby before the bolster 4 is carried into the press machine 1. It is discharged and accommodated in a pallet 19 set in the direction of the position.

On the other hand, if the seesaw type chute 7 on the side of the bolster 3 is inclined from the beginning as shown in Fig. 7b, and if the seesaw type chute 7 on the side of the bolster 4 is inclined as shown in Fig. 7a from the beginning, the bolster 3 and 4 are moved in the direction of the press apparatus 1, the rollers 14 of the protruding member 12 do not come into contact with the locking members 17 and 18, so that they are carried into the press apparatus 1 while maintaining the original inclined state. Therefore, similarly to the embodiment described above, the punched member is ejected toward the standby position of the bolsters 3, 4.

In the above embodiment, the discharge conveyors 8 and 9 are provided below the seesaw type chute 7, but
By adjusting the length of seesaw type chute 7 or increasing the height of holding member 5, it is possible to easily move the punching member to the outside of bolsters 3 and 4 without providing both conveyors 8 and 9. It can be discharged. Further, although an example in which the locking members 17 and 18 are attached to the supports 2a and 2b of the press device 1 has been described, other fixing parts may be used.

As explained above, according to this invention, the seesaw-type chute can be automatically moved in seesaw motion to eject the punched member in the direction where the bolster does not exist, so a large space for storing the punched member can be secured for work. This has the advantage of improving sexual performance.
