DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a static mixing part material, and more particularly, to a method for manufacturing a static mixing part material by only one bending process.

[0002]

2. Description of the Related Art As a static mixing part material formed by bending a plate material, there is Japanese Patent Publication No. 55-37941.
And JP-B-54-21987 and JP-A-49-127261 are known.

The parts shown in FIG. 1 of Japanese Patent Publication No. 55-37941 are cut into left and right and formed in a wedge shape. The parts shown in FIGS. 1 and 2 of Japanese Patent Publication No. 54-21987 have the upper wings of the two wings on one side of the intermediate belt folded forward, and the lower wings on the back. The wings, which are opposite to the wings via the intermediate band, are bent in opposite directions. The parts shown in FIGS. 1 and 2 are mirror images, and the wings are formed in opposite directions. FIG. 1 of JP-A-49-127261 discloses a part material in which an upper half and a lower half are bent to opposite sides, respectively.

[0004]

However, the conventional static mixing parts are formed by bending a plate in two or more directions. Therefore, in order to manufacture a conventional part material, it is necessary to perform a bending press operation twice or more, and it is necessary to prepare a plurality of press dies.

[0005] In addition, since there are wings in different directions in the intermediate band portion of the obtained part material, there is a problem that the combination of the part materials is limited.

Therefore, the present invention can be bent only by pressing once, and only one type of press die is required, so that the manufacturing operation can be simplified, the manufacturing cost can be reduced, and the obtained parts can be reduced. It is an object of the present invention to provide a method of manufacturing a static mixing parts material in which the materials can be freely combined.

[0007]

According to the present invention, there is provided a method of manufacturing a static mixing parts material, comprising forming an intermediate band and wings having a constant width on both sides of the intermediate band. At the same time, the other side of the wing portion is notched through the intermediate band body, and the wing portion is bent in the same direction by only one bending process along the bending line.

In the method for manufacturing a static mixing parts material according to the present invention, a plate material is punched by a press machine to form an intermediate band and wings having a fixed width on both sides of the intermediate band. The wing portion is cut out on the opposite side of the wing portion, and the wing portion is bent in the same direction along the bending line by only one bending at the same time as the punching by the press machine.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In order to manufacture a static mixing part material, a plate material 1 as shown in FIG. 1 is prepared, and the plate material 1 is punched or cut out, and fixed to both sides of the intermediate band 2 and the intermediate band 2. A wing 3 of width is formed. The outer shapes of the intermediate band 2 and the wings 3 on both sides are cut out from an ellipse.

Therefore, in order to form the intermediate band 2 and the wings 3 on both sides, an elliptical plate may be prepared in advance and cut out.

As the plate material 1, it is preferable to use a thin plate material in consideration of the easiness of bending, and the thickness is 0.5 to
About 5 mm is preferable. The plate is formed of a metal steel plate, preferably a stainless steel plate.

The intermediate band 2 is arranged in the major axis direction of the ellipse,
The wings 3 on both sides are arranged at right angles to the intermediate band 2. In the drawing, a gap 4A is formed between the wings 3 located on the right side of the intermediate band 2, and cutouts 4 are formed above and below the wings 3 located on the left side.

In the figure, two wings 3 are provided on the right side of the intermediate band 2,
Although one sheet is formed on the left side, the number can be increased. The width of the wing 3 can also be increased or decreased with respect to the width shown.

The width of the intermediate band 2 can be made larger or smaller than the width shown in the figure, depending on the type of fluid and the degree of mixing and stirring required.

Next, in order to form a static mixing part material 6 from the intermediate band 2 and a part material preliminary body having the wings 3 having a fixed width formed on both sides of the intermediate band 2, the wings 3 are formed. The wing is bent in the same direction along a bending line 5 defining both sides of the wing.

Such bending can be performed by a press machine, and in the present invention, the static mixing parts 6 can be formed by one bending. One type of die for use in the press machine may be prepared for manufacturing one static mixing part material 6.

It is preferable that the punching and the bending are simultaneously performed by the same press machine in order to make the work more efficient and to enable mass production.

The bending angle is determined by how to design the shape of the lattice space obtained by combining a plurality of static mixing parts 6.

FIG. 2 shows an example in which two static mixing parts 6 obtained by bending at 45 ° are combined, and FIG. 3 shows the shape of the lattice space 7 obtained by the combination. I have.

Since the static mixing parts manufactured by the present invention are formed by one bending, their shapes are simplified, and the parts can be freely combined. For example, in the example shown in FIG. 3, the respective wings are fitted in the gap 4A or the notch 4 facing each other, and in the example shown in FIG. 4, the back surfaces of the intermediate bands 2, 2 are fixed to each other. It was done.

[0022]

As described above, according to the present invention, manufacturing can be simplified by only one bending, so that the manufacturing operation can be simplified, and when a single static mixing part material is manufactured, a pressing die is not used. Since only one type needs to be prepared, the manufacturing cost can be reduced. Further, according to the present invention, the shape of the obtained part material is simple, so that it can be freely combined and the versatility of the part material itself is high.
