Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a device for receiving scrap that falls and is discharged during press working.

BACKGROUND OF THE INVENTION Scraps produced by press processing such as punching and trimming are normally discharged from the press die by a shooter, as shown in FIG. 4, an example of which is shown in FIG. In other words, the movable bolster 1 includes a press mold (not shown) and a shutter 2.
is attached, and a scrap hole 4 into which scrap 3 is input is provided near the movable bolster 1 in the processing position, the shooter 2 is inclined downward at the scrap hole 4, and the scrap hole 4 The lid 5 is provided with a plurality of lids 5 that can be opened and closed individually so that it can be applied to scraps 3 of various sizes. In use, the number of lids 5 corresponding to the size of the scrap 3 is opened, a hollow frame-shaped scrap tray 6 is placed over the scrap hole 4 according to the size of the opening, and the scrap 3 is placed in the shutter. 2 to the scrap tray 6
It is dropped into the scrap hole 4 through the screw.

Problems that the invention aims to solve: However, when replacing the press die, the press die is replaced with the movable bolster 1, so it is necessary to remove the scrap tray 6 when setting up the die. Since it is necessary to attach and detach the scrap tray 6 and transport it, it takes time to set up the mold, and work efficiency is poor. It is also necessary to prepare scrap trays 6 of various sizes to match the size of the scrap, which reduces equipment costs. There were problems such as being bulky and requiring a large storage space.

This invention was made in view of the above-mentioned circumstances, and aims to provide a scrap receiving device that can speed up mold setup and has good storage properties.

Means for Solving the Problems In order to achieve the above object, this invention provides a horizontal direction along the side of the movable bolster to which the press die is attached, which is close to the scrap hole into which scrap is input. A pair of hinges that can be moved to adjust the mutual spacing is provided, and a side wall plate that rotates between a position parallel to the side surface and a position perpendicular to the side surface is attached to each hinge, and the scrap hole A cover plate is provided that rotates with an edge portion close to the side surface as a free end and another edge portion facing the edge portion as a rotation center, and further, a side edge portion of the side wall plate opposite to the hinge. A locking pawl is provided at the side end portion of the side wall plate to hold the cover plate standing upright so as to face the side surface, so that these side wall plates, the cover plate of the scrap hole in the open state, and the movable bolster are provided. The present invention is characterized in that a rectangular opening for the scrap inlet is formed by four sides.

Function Therefore, in this invention, the side wall plates attached to the movable bolster are opened, and the lid plates of the scrap holes are opened according to the spacing between the side wall plates, and the lid plates are erected vertically and held in an upright state by the locking claws. Then, a rectangular scrap inlet is formed by these side wall plates, the cover plate of the scrap hole, and the side surface of the movable bolster. In that case, by adjusting the spacing between the side wall plates, the inlet can be adapted to the size of the scraps. In addition, by folding the side wall plate so that it is in close contact with the side of the movable bolster, it can be stored in a stored state.Therefore, there is no need to attach and detach it every time when setting up the mold, and it can be integrated with the movable bolster. , does not require special storage space.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of this invention, showing a press die (not shown) and a shooter 10.
Of the side surfaces of the movable bolster 11 to which the movable bolster 11 is attached, a rail 13 that runs in the horizontal direction is provided on the side that is close to the scrap hole 12.
A pair of hinges 14 are movably attached to 3. As shown in FIG. 2, these hinges 14 have a structure in which a rotating arm 16 is attached by a pin 17 to a sliding body 15 that is movably fitted onto a rail 13. A side wall plate 19 having approximately the same width as the width of the scrap hole cover 18 is attached to each side wall plate 19, and therefore, the side wall plate 19 is held so as to rotate between a storage position parallel to the side surface of the movable bolster 11 and a position perpendicular to the side surface. has been done. Further, at the tip of each rotating arm 16, a claw 20 is formed by bending inward (in a direction facing each other) at right angles, and the scrap hole cover 18 in an open state is held in a vertical state by the claw 20. It is configured like this.

Therefore, in the above device, by moving the hinge 14 along the rail 13, the interval between the side wall plates 19 is adjusted to the interval corresponding to the size of the scrap 3 produced by press working, and then each The side wall plate 19 is rotated to a position perpendicular to the side surface of the movable bolster 11 so that they face each other, and the scrap hole cover 18 between them is pulled open and the scrap hole cover 18 is held in a vertical position by the claw 20. Hold. As a result, each side wall plate 19, the scrap hole lid 18, and the side surface of the movable bolster 11 form a rectangular frame in place of the conventional scrap tray at the opening of the scrap hole 12.

When changing the mold, remove the scrap hole cover 18 from the claw 20 and close it.
The side wall plate 19 is attached to the movable bolster 1 as shown in FIG.
1, and in that state, move and replace the press mold together with the movable bolster 11.

After the mold is replaced, if the size of the scrap 3 produced by the press work is different from that before, the distance between the side wall plates 19 can be adjusted by moving the hinge 14 along the rail 13. Adjust the pitch to a predetermined pitch, with one of the scrap hole lids 18 as one pitch, and open the number of scrap hole lids 18 that matches the spacing between the side wall plates 19.
to hold it in the vertical position.

Effects of the invention As is clear from the above explanation, according to the device of this invention, the side wall forming a part of the input port can be folded and integrated with the movable bolster, so that it can be attached to the movable bolster. Since mold setup can be carried out on the fly and the spacing between side wall plates can be adjusted, one type of device can handle scraps of various sizes, and therefore, according to this invention, Attaching and detaching the scrap tray
Because it eliminates troublesome work such as transportation, mold setup can be speeded up, and because it has the flexibility to be applied to scraps of various sizes, there are fewer models to keep on hand, and as a result, ,
It is possible to obtain excellent practical effects such as being able to eliminate or extremely reduce storage space.
