BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

The processing position of the band-shaped plate 1 is intermittently transferred to the pressing device 2, and when stopped, the pressing portions 2A, 2B,... Of the pressing device 2 perform pressing. Each time the working of the press working device 2 is completed, the band-shaped plate material 1 is transported again by a predetermined amount, and the press working is performed by the press working device 2 again.

[0010] The intermittent transfer and the press working by the press working device 2 are repeated as described above to continuously process the strip-shaped plate material 1 into a continuous uneven shape.

In this press working, first, the first press working portion 2A on the transfer leading end side is operated, and a predetermined working position of the strip-shaped plate material 1 is pressed.

In a state where the first press section 2A performs the pressing operation and presses the strip-shaped plate material 1, the second press processing on the opposite transfer base end side is delayed after the operation of the first press section 2A.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

This embodiment is applied to a continuous processing method for a ring as shown in FIG.

The press working apparatus 2 of this embodiment has a plurality of press working sections 2A, 2B,... Arranged side by side at predetermined intervals along the transfer direction of the band-shaped plate member 1 and an appropriate transfer apparatus. The belt-shaped plate material 1 transferred by the above-mentioned is sandwiched from the opposite direction.

Are formed at opposite ends of a rod-shaped moving body 3 which moves in and out of the opposing direction, and the opposing press sections 2A, 2B,...
Are configured so that when they protrude inward, the moving bodies 3 that are adjacent to each other are engaged.

Further, a rod-shaped fixed body 4 for positioning and fixing the strip-shaped plate 1 at the time of press working is provided on the transfer front side of the first press working part 2A.
.. Perform the press operation before B,... Perform the press operation, and are configured so that the press working portions 2A, 2B,. I have.

The operation of the press working device 2 is as follows. First, after the first press working portion 2A on the transfer leading end side of the strip-shaped plate material 1 projects, the press working by the projecting operation of the first press working portion 2A is completed. The second press working portion 2B on the opposite transfer base end side protrudes later than the operation of the first press working portion 2A so that the next press working is performed, and thereafter, the press working portions 2C, 2D, .. Are configured to protrude one after another from opposite sides with a time difference.

Since the structure of the press working device 2 and the operation mechanism of each press working portion 2A, 2B,... Can be appropriately designed and modified, the structure is illustrated and described in detail. Things are omitted.

Therefore, each of the opposing press working sections 2
A, 2B,..., The strip-shaped plate material 1 is fed between them, and the press working device 2 is operated. As shown in FIG. The processing part 2A protrudes and press-deforms the processing part of the strip-shaped plate material 1. Then, the first press processing part 2
In the state where A performs the pressing operation and presses down on the strip-shaped plate member 1, the second pressing portion 2B on the transfer base end side on the opposite side operates after the operation of the first pressing portion 2A, and the first pressing process. After the pressing of the portion 2A is completed, the band-shaped plate 1 is pressed by the second pressing portion 2B. Thereafter, similarly, the press working parts 2 which are arranged side by side
.. C, 2D, 2E, 2F... Are pressed one after another from opposite sides with a time lag to press and bend the band-shaped plate material 1,
The strip-shaped plate 1 is configured to be continuously pressed into a continuous uneven shape having a continuous deformed cross-sectional shape.

In the actual press working apparatus 2, the step of performing the above-mentioned press working is regarded as a first step, and a part of the top of the convex portion of the band-shaped plate material 1 is formed in a square at the transfer front end side of the first step. A second step for molding is arranged, and a third step for further adjusting the predetermined shape molded in the second step is arranged on the transfer leading end side of the second step.

Further, in this case, the transfer device and the like are controlled so that the processed part pressed in the first step is transferred to the second step, and the processed part pressed in the second step is transferred to the third step. .

That is, after the completion of the forming in the first step, the processing point (continuously uneven portion) of the transfer tip of the strip-shaped plate 1 is transferred to the second step and stopped, and the continuous unevenness is processed by the processing in the second step. The shape is formed into the above shape. Further, at this time, the processing position of the strip-shaped plate material 1 transferred to the first step is processed in the first step into a continuous uneven shape.
Is formed into a shape as shown in FIG.

When the processing point at the transfer tip of the strip 1 is finished in the second step, it is then transferred to the third step and stopped, and the shape is adjusted and processed by the processing in the third step. It ends. At this time, a portion located in the first step in the previous stage is processed in the second step at the same time, and a portion located in the first step is newly processed into a continuous uneven shape.

This operation is repeated to perform continuous press working.
The strip-shaped plate 1 is formed into a predetermined shape.

After the completion of the forming by the press working device 2, the band-shaped plate material 1 is bent into a ring shape by a suitable bending device, and then the bent band-shaped plate material 1 is cut into a suitable peripheral length, as shown in FIG. The ring is formed as shown in FIG.

Further, in the press working apparatus 2 of the present embodiment, each press working part 2 that performs the press operation with the above-mentioned time difference is used.
A, 2B,..., For example, are set to operate every other, and the press working parts 2A, 2B,.
By, for example, changing the interval of the opposed juxtapositions in the meshing state, it is possible to easily change the formation pitch of the continuous uneven shape and to form an unprocessed portion having no uneven portion in a predetermined range.

Further, in the method of processing a band-shaped plate material prior to the earlier application filed by the present applicant described in the section of the prior art, the meshing gears are vertically arranged, and the band-shaped plate material is meshed with the meshing portion of the meshing rotating upper and lower gears. In order to form a continuous uneven shape while transferring the band-shaped plate material by inserting a strip, this processing method is widely practiced at present.

On the other hand, this kind of ring is used by abutting the cut portions functionally as shown in FIG. However, in the above-described gear processing, since a shape having no non-processed portion is formed, a part of the formed portion must be cut in order to form a cut portion for abutting, and this is the case. The shape of the cut surface was likely to vary or cut errors were likely to occur, and even if the cut surfaces were abutted, it was likely to be unstable. Therefore, in some cases, it is necessary to process only this cut surface in a separate process in order to stabilize the butted surface.

In this respect, in the present embodiment, since a non-processed portion within a predetermined range can be easily formed at an arbitrary position as described above, the band-shaped plate member 1 can be formed for each length capable of forming one ring. If the operation control or the interval between the opposing press working sections 2A, 2B,... Is set so as to form a non-processed portion in a predetermined range, the non-processed portion formed by this is cut. Then, if this cut end is bent as shown in FIG. 4, it is possible to easily form an abutting surface capable of stably abutting. Further, by changing the cutting position and the bending position of the unprocessed portion, the circumference of the ring can be adjusted, and this adjustment can be performed very easily.

[0034]

According to the present invention, as described above, a plurality of press working parts alternately press and bend a band-shaped plate material from opposite sides from a transfer leading end side to a base end side with a time lag. As compared with the configuration in which a plurality of press dies descend from the upper side only at a time difference to perform press working as described in the earlier application, a better pull-in preventing action of the material at the time of press working can be obtained. Press working without error can be performed.

Accordingly, the accumulated error due to the continuous and repeated press working is further reduced as compared with the prior application, and the working accuracy of the band-shaped plate material is further greatly improved. This is a continuous processing method for plate materials.

In the present invention, since a plurality of press working parts are alternately pressed from both sides facing each other,
As in the prior application described in the prior art, the present invention is not limited to an apparatus configuration in which the press processing section descends from the upper side toward the lower mold, and processing using various types of press processing apparatuses becomes possible. It is a revolutionary continuous processing method for strip-shaped plate materials with excellent practicality.

According to the second or third aspect of the present invention, it is possible to easily adjust the pitch of the continuous uneven shape formed on the strip-shaped plate material, and to set a predetermined range at an arbitrary position of the strip-shaped plate material. It becomes even more practical because it is possible to easily form a non-processed portion having no unevenness processed portion.
