Description

[Detailed Description of the Invention] The present invention relates to a processing oil separation scrap chute.

Scraps produced by press working include relatively large scraps, such as those produced by trimming, and small scraps, such as those produced by piercing, and their sizes are not constant.

On the other hand, the chute is required to have a function that allows scrap to flow out without stagnation.

The present invention has been made to provide a sheet that meets these requirements.

The present invention will be explained based on the drawings of two embodiments.

FIG. 2 shows a side cross section of the scrap chute 1.

In order to give inertia to the scrap, the scrap chute is fixed in the bed 2 and connected to the scrap chute 3.
Divided outward and arranged in stages at predetermined intervals,
The structure is such that processing oil is allowed to fall from gaps 5 between each divided chute member 4, thereby separating scrap and processing oil.

Note that the clearance 5 needs to have a certain size to ensure that the processing oil can fall, but if the scrap is small, the scrap will fall from the clearance 5 along with the oil, so In order to prevent this, an oil permeable member (hereinafter referred to as a flap) that can be opened and closed in a direction extending downward from the inclined surface of each chute member 4.

) will be established. In the first embodiment, a flap 6 formed of a net-like member is used as the flap, as shown in FIG.
In the second embodiment, as shown in FIG. 4, a flap 6' formed of a perforated plate is used.

Note that in the first embodiment and the second embodiment, the flap 6.
The only difference is 6', and the other components are all the same and operate the same, so the description of the first embodiment will be continued below.

A rotating shaft 7 for opening and closing the flap 6 is attached to the flap 6, and is supported by a bearing 8 specially provided on the sea-1 member 44.

A pinion 11 is fixed to one end of the rotating shaft 7 and engages with a rack 10 that is guided by a bearing 9 protruding from the side wall 1a of the scrap chute 1 and moves in the direction of the arrow.

Next, the operation of the present invention will be explained.

Since the first embodiment and the second embodiment have exactly the same effect, the explanation will be based on the first embodiment, and the explanation of the second embodiment will be omitted.

During press working, if the scrap that falls along with processing oil through the scrap chute 3 fixed in the bed 2 is smaller than the gap 5 between the chute members 4, the rack 10 is moved as shown in Figs. 2 and 3. By keeping the flap 6 in the extending direction of the inclined surface of the chute member 4, scraps are discharged as they are without falling from the gap 5, and only processing oil is allowed to fall from the flap 6 and collected in a tank 13.

On the other hand, when the scrap is larger than the gap 5 between the chute members 4, the rack 10 is moved, the flap 6 is rotated and folded under the rotation axis 7 of the pinion 11, and the scrap is processed from the gap 5 of the chute member 4. Only the oil flows down and the processing oil can be separated from the scrap.

According to the present invention having the above-described structure and operation, the rack 9 is moved according to the size of the scrap, and the gap 5 between the chute members 4 is opened and closed, thereby efficiently separating processing oil from the scrap.

In the first embodiment, since the flap 6 is formed of a net-like member, the permeability of machining oil is high and the degree of recovery of machining oil is good.

Furthermore, in the second embodiment, the flap is formed of a perforated plate, so it is easy to manufacture.
