Description

[Detailed Description of the Invention] The present invention relates to a scrap conveying device installed in a press machine.

Conventional scrap conveying devices include, for example, those shown in FIGS. 1 and 2, and those shown in FIGS. 3 and 4.

That is, in the former case, the upper die 11 is attached to the ram 1, the lower die 21 is attached to the bolster 2 via the block 22, and a belt conveyor 23 is installed in the space between the lower die 21 and the bolster 2 at both ends of the bolster 2. The lower die 21 is placed across the
Scraps 24 dropped into the space from the discharge hole are received on a belt conveyor 23, conveyed to the end of the bolster 2, and collected on a pallet 25. In the latter case, a press machine is installed in a pit 3 dug from the ground level, a scrap outlet 26 is opened in the bolster 2, and a belt conveyor 27 is arranged in the space below to convey the scrap 24 from the space to the ground. During press working, the scrap 24 that passes through the discharge hole of the lower mold 21, passes through the scrap discharge port 26 of the bolster 2, and is discharged into the space below is received by the belt conveyor 27, conveyed from the pit 3 to the ground, and is then transferred to the pallet 25. The belt conveyor 27 is provided with a scriber 27a protruding from the surface to prevent the scraps 24 from falling off.

However, in such a conventional scrap conveying device, in the former case, the scraps 24 tend to be scattered on the upper surface of the bolster 2, and the scraps 24 tend to fall into the mold tightening T-shaped grooves 28 formed in multiple stripes on the upper surface of the bolster 2. This has the problem that it gets in the way when changing molds and takes time to clean. In the latter case, the pit 3 is required, which increases equipment costs, and the height of the press itself increases, which may cause problems with installation rigidity.Although it can be adopted for large machines, it is not easy to use for small machines, etc. There was nothing that could be adopted. Furthermore, since the scriber 27a must be provided on the belt conveyor 27, there is a problem that the cost of the belt conveyor 27 increases.

The present invention was developed by focusing on these conventional problems, and it has been developed to create a scrap machine that hardly increases the cost of equipment and that can efficiently collect and transport scraps without scattering them. The purpose is to provide a conveyance device.

In order to achieve this purpose, in the present invention, a conveying groove that extends below the surface of the press press's bolster is formed across this bolster, and a belt conveyor for conveying scrap is disposed to pass through this conveying groove. , the scraps are collected in a conveying groove and conveyed.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Note that the same parts as in the conventional example are given the same reference numerals, and redundant explanation will be omitted.

5 to 10 show an embodiment of the present invention, in which the grooves extend downwardly from the surface of the bolster 2 and cross the bolster 2 in a direction perpendicular to the T-shaped grooves 28, 28, . A conveying groove 4 is formed, and a belt 51 of a belt conveyor 5 for conveying the scrap 24 through the conveying groove 4 is disposed.

A groove-shaped protection member 41 is attached to the conveyance groove 4 to guide the belt conveyor 5, protect both ends of the belt 51, and close the openings at the ends of the T-shaped grooves 28, 28, .

The belt conveyor 5 is a general type, and includes a driving drum 52 at one end and an idle roller 53 at the other end.
As shown in FIG. ,57,... is fixed to one side of the press machine,
Similarly, as shown in FIG.
is supported by a support arm 58 via a pivot 59,
A base plate 60 supporting the support arm 58 is fixed to the other side of the press machine with bolts 61, 61, . . . . Further, a tension adjustment idle roller 62 is provided adjacent to the drive drum 52.

In the scrap conveying device having the above configuration, as shown in FIGS. 9 and 10, if the drive drum 52 is rotated and the belt conveyor 5 is operated during the press work, the scraps will be punched or cut. The scraps 24 thus obtained fall into the conveying groove 4 through a discharge hole provided in the lower die 21, ride on the belt 51 of the belt conveyor 5, are conveyed to the end of the bolster 2, and are collected on a pallet 25 there.

The groove-shaped protection member 41 provided in the conveying groove 4 prevents the scrap 24 from scattering from the end of the mold clamping T-groove 28 into the belt conveyor 5.
to protect the edge of the belt 51.

According to the scrap conveying device according to the present invention, a conveying groove is provided that extends downward from the surface of the bolster, and the belt of the belt conveyor is passed through the groove to collect and convey the scraps. There is almost no chance that the scraps will be scattered or get into the T-groove, and there will be no need to spend time cleaning when replacing the mold, so the replacement time will be shortened. In addition, the cost can be reduced by simply forming a conveying groove on the bolster, and there is no need for large-scale construction work such as digging pits, and there is no effect on the installation rigidity of the press machine, making it an extremely rational scrap conveying device for use in press machines. be.
