Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a concave and convex shape on a metal plate surface.

[0002]

2. Description of the Related Art When a metal plate as a connecting plate is joined to a connection portion where metal plates are continuously connected and bolted together, the connecting plate is connected so as to bite into the metal plate as a base material. It is effective to use a metal plate which is formed by subjecting a joint surface of a metal plate to a continuous mountain-shaped unevenness process. Further, there may be a case where the surface of the metal plate is desired to be subjected to continuous mountain-shaped unevenness simply for the purpose of decoration or other necessity. The shape of the continuous crest-and-groove may be a pointed tip or may have a rounded waveform.

[0003] In the case of forming a continuous mountain-shaped unevenness on the surface of such a metal plate, conventionally, cutting using a cutting tool (blade) has generally been performed.

[0004] However, if cutting is performed using a cutting tool to form continuous mountain-shaped irregularities on the surface of the metal plate, the cutting efficiency is poor because the cutting portion is large and the cutting operation requires a lot of time. The cost was undeniable.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been devised in view of the above-mentioned problems of the conventional cutting method using a cutting tool for forming a continuous mountain-shaped unevenness on the surface of a metal plate. The use of press working to realize the formation of continuous mountain-shaped irregularities on the surface of a metal plate, greatly shortening the working time of working, improving work efficiency, and controlling costs. It is an object of the present invention to provide an extremely economically advantageous method of processing a continuous chevron on a metal plate surface.

[0006]

In order to achieve the above-mentioned object, in the method of the present invention for forming a continuous concave and convex pattern on a metal plate surface, first, a predetermined continuous ridge-shaped concave and convex pattern 2 is cut and formed. Is pressed against a side end surface of the metal plate 3 in a direction parallel to the surface of the metal plate 3 serving as a workpiece.
The method is characterized in that a predetermined continuous ridge-shaped unevenness 6 is formed on the surface of the metal plate 3 by processing, and secondly, a predetermined continuous ridge-shaped unevenness 2 is formed by engraving. The press die 1 is pressed against the side end surface of the metal plate 3 in a direction parallel to the surface of the metal plate 3 to be processed, and a predetermined continuous ridge-shaped unevenness 6 is formed on the surface of the metal plate 3. Then, by pressing the metal plate 3 on the other end surface in a state where the metal plate 3 is turned by 90 degrees in the same manner, the quadrangular pyramid-shaped mountain-shaped unevenness 7 continuous to the plate surface of the metal plate 3 is formed. It is characterized by the following.

[0007] According to the method of the present invention for forming a continuous concave and convex shape on the surface of a metal plate according to the present invention, a predetermined continuous ridge-shaped concave and convex shape 6 on the surface of the metal plate 3 by using a press working method. Furthermore, continuous quadrangular pyramid-shaped mountain-shaped irregularities 7
Can be formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on embodiments with reference to the drawings.

[0009]

First Embodiment In FIGS. 1 to 3, reference numeral 1 denotes a press die, which is formed by engraving a predetermined continuous ridge-shaped mountain-shaped unevenness 2 on a side surface and quenching. Reference numeral 3 denotes a metal plate as a workpiece.

The press die 1 is mounted on a base 4 for guiding up and down. Then, the press die 1 is pressed against the side end surface of the metal plate 3 in a direction parallel to the surface (working surface) of the metal plate 3 as a workpiece fixed to the fixture 5. The number of times of pressing is suitably about 1 to 3 times as necessary.

As a result, as shown in FIG. 3, a predetermined continuous ridge-shaped unevenness 6 can be formed on the surface of the metal plate 3.

The tip of the ridge-shaped mountain-shaped unevenness 6 may have a pointed shape or a corrugated shape.

[0013]

Embodiment 2 In the second embodiment, the metal plate 3 obtained by working the predetermined continuous ridge-shaped unevenness 5 obtained in the first embodiment is further processed by the metal plate 3 if necessary. Is turned by 90 degrees, and a press is applied using a press die 1 in the same manner as in the first embodiment.

In other words, the metal plate 3 was obtained by processing and forming a predetermined continuous ridged mountain-shaped unevenness 6 on the surface by the processing method in Example 1. As shown in FIG. The direction of the plate 3 is changed by 90 degrees, and the plate 3 is fixed to the fixture 3. Under this condition, the press die 1 is pressed on the other end surface of the metal plate 3 in the same manner as in the first embodiment.

As a result, as shown in FIG. 5, a predetermined continuous quadrangular pyramid-shaped mountain-shaped unevenness 7 can be formed on the surface of the metal plate 3.

The tip of each quadrangular pyramid-shaped mountain-shaped unevenness 7 may be a pointed shape or a rounded wave shape.

[0017]

As described above, the present invention enables continuous ridges or quadrangular pyramids to be formed on the surface of a metal plate by press working. The time can be greatly shortened, the working efficiency can be greatly improved, and the effect of being suitable for mass production and suppressing the processing cost can be achieved.
