BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated pitch adjusting device for a corrugated metal plate or the like, which adjusts a corrugated pitch of a corrugated metal plate or the like to a predetermined pitch.

[0002]

2. Description of the Related Art When a sheet material such as a metal plate is corrugated by a forming roller or the like having an uneven surface corresponding to the corrugated shape of the corrugated plate, the corrugated pitch of the formed corrugated plate is irregular. Has become.

For this reason, when the number of waves of the corrugated plate is counted and the corrugated plate is cut, the length of the cut corrugated plate becomes irregular, and the corrugated plate is cut into a fixed length. Can not do.

For example, in the case of a corrugated plate used as a radiator fin of a heat exchanger, a corrugated pitch adjusting device for adjusting the corrugated pitch of the corrugated plate to a predetermined pitch is provided in a production line.

FIG. 4 is an explanatory diagram schematically showing an example of a conventional waveform pitch adjusting device. As shown in FIG. 4, in this waveform pitch adjusting device a, a corrugated plate d is pressed onto a horizontal work board e with a predetermined pressing force by a pressing plate c provided with a spring b, and the uneven surface with a predetermined pitch is formed. The pitch adjusting roller f is engaged with the corrugated plate d from both the upper and lower sides of the corrugated plate d and rotated at a predetermined peripheral speed V, and the corrugated plate d is sent out in the feed direction X by the pitch adjusting roller f, so that the waveform is obtained. The waveform pitch of the forming plate d is roughly adjusted to a predetermined pitch between the pressing plate c and the pitch adjusting roller f, and the pitch is finally adjusted to a predetermined pitch by the pitch adjusting roller f.

However, in the conventional waveform pitch adjusting device a, the pulsation is generated in the corrugated plate d when passing through the pressing plate c, so that the pressing plate c and the pitch adjusting roller f
In some cases, the feeding of the corrugated plate d becomes unstable.

[0007] In this case, the waveform pitch of the corrugated plate d roughly adjusted between the pressing plate c and the pitch adjusting roller f becomes irregular. In the worst case, the waveform formed by the pitch adjusting roller f becomes irregular. At the time of the final adjustment of the waveform pitch of the formed plate d, the pitch adjusting roller f causes the waveform crush to bite the waveform of the waveform formed plate d, and the product yield of the waveform formed plate d whose waveform pitch is adjusted is reduced.

Therefore, according to the present invention, it is possible to eliminate the collapse of the waveform when the waveform pitch of the corrugated plate is fully adjusted,
As a result, it is an object of the present invention to provide a corrugated pitch adjusting device for corrugated plates that can improve the product yield of corrugated plates with adjusted corrugated pitch.

By increasing the speed, the minimum pitch is enlarged between the first and second pitch adjusting rollers to roughly adjust the pitch to a predetermined pitch.

According to the second aspect of the present invention, adjacent to the corrugated plate in the feed direction of the corrugated plate before the first pitch adjusting roller, the corrugated surfaces adjacent to each other are brought into contact with each other to reduce the corrugated pitch of the corrugated plate to the minimum pitch. The waveform pitch of the waveform forming plate before the waveform pitch adjustment is eliminated by adjusting the waveform pitch of the waveform forming plate to the minimum pitch before the first pitch adjusting roller in the feed direction. Can be.

Therefore, according to the third aspect of the present invention, the forming of the plate material into the corrugated plate by the forming roller and the adjustment of the corrugated pitch of the corrugated plate to the predetermined pitch by the first and second pitch adjusting rollers. Can be performed continuously.

[0018]

According to the first aspect of the present invention, the corrugated plate can be stably sent out at a constant sending speed in the feeding direction by the first pitch adjusting roller.
The irregularity of the waveform pitch of the corrugated plate roughly adjusted between the two pitch adjusting rollers can be reduced as compared with the conventional product using the pressing plate. In addition, it is possible to eliminate the waveform crushing in which the second pitch adjusting roller bites the waveform of the corrugated plate, thereby improving the product yield of the corrugated plate whose corrugated pitch is adjusted.

According to the second aspect of the present invention, the irregularity of the waveform pitch of the waveform forming plate before the adjustment of the waveform pitch is determined by the minimum pitch of the waveform pitch of the waveform forming plate before the first pitch adjusting roller in the feed direction of the waveform forming plate. When the first pitch adjusting roller meshes with the corrugated sheet, the first pitch adjusting roller meshes the corrugated sheet when the corrugated sheet is fed in the feed direction. Can be eliminated, and as a result, the product yield of the corrugated plate having the corrugated pitch adjusted can be improved.

According to the third aspect of the present invention, the forming of the sheet material into the corrugated sheet by the forming roller and the adjustment of the corrugated pitch of the corrugated sheet to the predetermined pitch by the first and second pitch adjusting rollers are continuously performed. Therefore, it is possible to reduce the size of a manufacturing facility for manufacturing a corrugated plate having a corrugated pitch adjusted from a plate material, and to reduce the manufacturing space for the manufacturing facility.
