Abstract

PURPOSE:To enable an inverse operation based on unidirectional movement of material by synchronously rotating an upper and a lower die a fixed angle when the material is blanked by the upper and the lower die while it is fed at a fixed stroke. CONSTITUTION:The material 1 is moved at a fixed stroke and blanked between the upper die 2 provided with a punch 6 and the lower die 3 provided with a die 7. At this time, gear tooth parts 8, 9 are provided on nearly 180 deg. parts of the respective circumferential surfaces of the upper and the lower due 2, 3 and are engaged with the gears 12, 13 driven by motors 14, 15 rotating in the forward and backward direction. In this constitution, the punch 6 of the upper die 2 is lowered to punch the material between the punch 6 and the die 7, then, the punch 6 is lifted, the motors 12, 13 are rotated synchronously and the upper and the lower die 2, 3 are rotated 180 deg. through the gears 8, 9 and the gear tooth parts 8, 9. In the meantime, a fixed feed is given by feed mechanisms 4, 5 to the material and the material is blanked again by the fall of the punch 6. When this operation is repeated, the material 1 fed in one direction is punched efficiently and in a good yield.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is provided with an upper die and a lower die, and is used in press machines and similar machines for carrying out operations such as shearing of materials between them. Concerning the auxiliary equipment embankment proposal.

[Conventional technology]

Conventionally, for example, when cutting out a shape as shown in Figure 3 a with one die, the material was cut out as shown in Figure 4, as shown in C, or the material as shown in Figure 5, d. A method is used in which the material is first drawn out, then the material is turned over in the opposite direction, and the material is drawn out again as shown in e of Fig. 6.

[Problem that the invention seeks to solve]

The former method, ie, the method shown in FIG. 4, has the disadvantage that the material cannot be used effectively.

The latter method, that is, the method shown in FIGS. 5 and 6, allows for effective use of materials.

-After cutting out the die as shown in Figure 5, there was a problem in that the same material had to be reversed and cut out again as shown in Figure 6, which was troublesome and required precision in cutting. .

[Means for solving problems]

Here, in this invention, a working member and a corresponding receiving member are respectively formed in an upper mold and a lower mold which are configured to sandwich a material to be fed with a predetermined stroke, and these upper mold and lower mold A rotation mechanism is attached to each of these to rotate them over a predetermined angle in synchronization.

A press machine characterized in that by reciprocating these rotating mechanisms, each of the work members and the receiving member is rotated by a predetermined angle to perform work, thereby enabling inverted processing by moving the material in a fixed direction. and its mllll
The authors proposed an auxiliary device for the machine, and thereby attempted to solve the problems of the prior art.

[Effect]

That is, for example, in a press machine equipped with the auxiliary device of the above structure of the present invention, while giving a predetermined feed to the material,
Each time, the upper mold and lower mold are rotated by a predetermined angle to perform so-called inverted punching (return punching), and the feeding of the material, the synchronous rotation of the upper mold and the lower mold, and the punching operation are continued. By doing so, by feeding the material in one direction, the work can be carried out extremely efficiently and the yield of the material can be improved.

[Example] Next, an example in which the present invention is applied to a press machine will be explained with reference to Figs. 1 and 2. This also applies to other processing machines.

The material 1 is fed by a predetermined stroke between an upper die 2 and a lower die 3 via, for example, gub feeding mechanisms 4 and 5. A bunch 6 as a working member is formed, and a corresponding diamond 5 as a receiving member is formed on the lower mold 3.

The upper die 2 and the lower die 3 are provided with grooves 8 and 9 extending approximately 180° on their circumferential surfaces, and these grooves 8.
Gears 12 and 13 that mesh with these toothed portions 8 and 9, respectively, are driven by forward and reverse motors 14 and 15, respectively, in order to constitute a rotation mechanism [011] together with gears 9 and 9.

In the above configuration, in the position shown in FIG.
After lowering the side bunch 6 and punching the material between it and the diamond, the bunch 6 is raised and the motor 12,
13 are rotated synchronously, and the upper die 2 and lower die 3 are rotated 180 degrees through the gears 8, 9 and the toothed portions 8, 9. During this period, the feeder *4.5 feeds the material N1 at a predetermined rate. is given, and the bunch 65i is lowered again to punch out the material 1 between it and the diamond, and by repeating the above operation, the material 1 is fed in one direction, so-called upside down punching (reverse punching). It is possible to do this. In addition,
In the above example, the upper die 2 and the lower die 3 are rotated by 1811 degrees, but this angle can be arbitrarily selected depending on the nature of the work.

〔Effect of the invention〕

By using the auxiliary device of the present invention having the above-described structure, it is possible to utilize the material at an extremely high yield by feeding the material in one direction, and the work can be carried out smoothly. It is.
