Description

[Detailed explanation of the idea] The present invention relates to a transfer device for press-cut scraps.

Conventionally, press-cut scraps (hereinafter referred to as scrap) have been processed by a method as shown in FIG. 1, for example.

That is, 1 is a press upper mold, 2 is a die, 3 is a pierced nut, 4 is a material to be punched, 5 is a cover, and 7 is a punched scrap, and the scrap 7 is sequentially passed through the press upper mold 1 and upwardly It was discharged and disposed of.

Therefore, in such a device, it is necessary to interrupt the work (lot) in the middle of the work and dispose of the scrap 7, which is extremely inefficient.

Therefore, in order to improve this problem, a scrap collection box 6 and an air nozzle 8 are arranged as shown in the figure, and compressed air is ejected from the air nozzle 8 in the direction of the arrow to blow away the piled up scraps 7 and open the collection box. 6, but with this structure, the blowing effect by air is not necessarily sufficient, and therefore, it is expected that the scrap 7 will accumulate and push up the upper cover 5, deforming it. Ru.

If this situation of scrap clogging progresses further, the punched scrap 7 may fall instead of rising, or the punching may be incomplete, resulting in deformation of the product, wear and tear on the mold, etc. This may lead to losses such as

The present invention has been devised in view of the above-mentioned circumstances, and aims to provide a device that solves the above-mentioned problems.

That is, in the present invention, a side plate is provided at an angle above the scrap take-out hole that opens upward through the upper press mold, and extends along the scrap transport direction, and a stabilizer is further installed from above the scrap take-out hole in the scrap transport direction. This is a scrap transfer device characterized in that the scrap is transferred by air.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a perspective view showing the scrap transfer device according to the present invention, in which 11 is a press upper die, 12 is a scrap, 1
3 is a hole provided through the press upper die for guiding and transferring the scrap 12 from below; 14 is a side plate provided at an angle on the side of the hole 13; 15 is a guide plate; 16 is an air nozzle; 17 is a This is a collection box for scrap 12.

As shown in FIG. 3, a plurality of guide plates 15 are arranged at intervals on the press upper mold 11 from the position of the scrap 12 to the collection box 17, and the inclination angle α thereof is approximately 4.
The angle is 0° to 50°, and the plate interval C and plate length D have a relationship of C≧D, forming an air stabilizer.

As shown in FIG. 4, the side plates 14 are arranged for each hole so that their upper ends extend over the holes 13 of the upper press mold 11.

The length of the side plate 14 is determined as appropriate depending on the position of the hole 13, and at both ends of the mold, as shown in FIG. The side plate 14' is extended to 17.

That is, a hole 13 for discharging the scrap 12 is provided in the upper die 11 as appropriate according to the specifications of the material to be punched, and the hole 13 is
The side plate 14 will be appropriately arranged in accordance with the position of.

Since the device according to the present invention is configured as described above,
Now, as the punched scraps 12 are gradually piled up, as shown in FIG. 4, the end faces thereof come into contact with the side plates 14 and gradually shift, until they finally collapse and fall.

At the same time, air is blown from the air nozzle 16 in the direction of the arrow, so that the scrap 12 that falls down is removed from the side plate 14.
It is blown away along the direction of the collection box 17.

In this case, the side plates 14, 14' guide the flow of air, and the guide plates 15 act as stabilizers, so that air is drawn in the direction of the arrow from between each guide plate 15 as shown in FIG. 3, and the scrap 12 is collected. This will encourage movement to box 17.

As described above, according to the device of the present invention, punched scraps naturally fall down due to the side plates, and can be reliably transported to a predetermined position and recovered using air and the help of a stabilizer.

Therefore, it is possible to completely prevent accidents such as deformation of equipment covers and products caused by clogging of scrap, wear and tear of molds, etc., and there is no need to interrupt work in the middle of the loft to collect scrap, improving operating efficiency. do.
