JP7036326B2 - Yin-Yang engraved mold roller with mutual meshing structure used for manufacturing embossed metal pipes - Google Patents

Description

The present invention relates to a yin-yang engraved mold roller having a mutual meshing structure used for manufacturing an embossed metal pipe.

More specifically, when an embossed pipe is manufactured using a pipe making machine that manufactures a metal pipe, the embossed metal plate is formed in the process of passing through the curved male-female meshing horizontal roller and the circular meshing horizontal and vertical rollers of the pipe making machine. In order to solve the problem that the formed uneven embossed pattern is deformed and the uneven embossed patterns do not match, making welding impossible, the embossed metal plate has a small width in the length direction on both side edges. By forming the plane of the embossed metal lower than the embossed pattern layer, it is possible to weld the seam in the length direction of the embossed metal pipe, and by forming a groove in the welded seam, the embossed metal prevents welding marks from appearing. It relates to an embossed mold roller with a mutual meshing structure that enables the production of plates.

The pipe making machine rounds the metal plate through the process of gradually increasing the degree of curvedness of the metal plate such as stainless steel plate, iron plate, copper plate, brass plate that is continuously supplied, and the end of the width of both sides of the rounded metal plate. It is a device that manufactures a circular metal pipe by matching and welding.

However, a technique for manufacturing an embossed pipe by the pipe making machine using an embossed metal plate manufactured by an embossed mold roller with meshing yin and yang as in the present invention has not yet been disclosed.

As a conventional technique in the field of embossed pipe manufacturing, a metal pipe obtained by melt extrusion of metal or a metal plate having a smooth surface is passed between horizontally installed male-female meshing curved rollers using a pipe making machine. While increasing the degree of curvedness, it is formed into a pipe shape by passing through a plurality of horizontally and vertically installed circular rollers that are meshed symmetrically, and the end faces of the widths of both sides of the pipe thus formed are matched. A technique for manufacturing an embossed pipe having a seam in the length direction obtained by welding has been disclosed.

As an example of the prior art, in the'metal pipe pattern forming machine'of Patent Document 1, when the plunger moves backward, the internal mold installed in the housing is pushed by the plunger and the inner peripheral surface of the metal pipe is pushed. It moves to the side, and as a result, the positive pattern processed on the outer peripheral surface of the inner mold meshes with the negative pattern processed on the inner peripheral surface of the outer mold, and between the inner mold and the outer mold. Disclosed is an embossing technique in which a character pattern is formed on the surface of a metal pipe located in.

In the'metal pipe embossing protrusion forming apparatus'of Patent Document 2, a moving fixing base installed and fixed in the center of the frame and a left and right moving fixing base installed and fixed to the frame are connected to the rear side of each. A cylindrical casing having a plurality of circular casing through holes is formed by moving and matching the inside of the plurality of circular casings by each of the first moving force generating members, and a metal pipe is placed in the cylindrical casing. After pushing it in so that it is in close contact with the metal pipe, the pipe-shaped core with punching is attached to multiple through holes drilled in the pipe-shaped circumferential surface is pushed in so that it is attached. However, the casing through hole formed on the inner surface of the cylindrical casing and the large diameter core through hole formed on the outer surface of the core are mounted and fixed so as to match, and are equal to the inner diameter of the core and the front end is circular. It is formed in a weight shape, and while the plunger whose body is a sealed body is pushed in by the strong pressure of the cylinder of the second moving force generating member, the cylindrical inclined surface at the front end of the plunger makes the diameter small. By pushing the curved portion of the lower end of the small diameter portion of the punch protruding inward from the through hole vertically upward, the punch of the dome-shaped large diameter portion integrated with the small diameter portion is also formed on the inner surface of the casing. A method for forming an embossed protrusion of a metal pipe, which forms a large number of protrusions on the pipe by being pushed up toward a through hole and bending and projecting the surface of the pipe, is disclosed.

These disclosed prior arts are embossing formed into a pipe between a female mold on the outer surface and a male mold on the inner surface of an extruded metal pipe, both of which are similar techniques. However, such embossing is not precise and elaborate, and is not a continuous process, so that there is a problem that productivity and competitiveness are inferior.

As another prior art, in the'improved structure pipe embossing apparatus'of Patent Document 3, a cylinder portion composed of a cylinder operated by pneumatic pressure and a piston operated by the cylinder, and a tip of the piston are used. A circular groove is formed in the metal pipe by pneumatically striking the multiple cylinders of the device composed of the formed embossed protrusions from positions at regular intervals in the direction perpendicular to the center line of the metal pipe. Techniques for forming devices are disclosed.
However, the embossing formed by such a device is an extremely simple embossing with an inscription, and has a disadvantage that a delicate and elaborate embossing cannot be obtained.

In addition, as a technique relating to an apparatus for embossing the outer peripheral surface of a pipe as described above, Patent Document 4's rhombus forming mold on the outer peripheral edge of the pipe and a forming method using the same, and Patent Document 5's'pipe wrinkle forming'. The technology for'device'has been disclosed.

However, as described above, the embossed pipes on the outer peripheral surface of the metal pipe having a smooth surface not only have a simple embossed pattern, but also cannot form a delicate and elaborate embossed pattern, and have a certain length. It is extremely inefficient because it is a device that attaches cut metal pipes one by one and embosses the outer peripheral surface of the pipes.

The present invention has solved the problem of the embossed metal pipe manufacturing apparatus, thereby completing an embossed pipe having an efficient but elaborate and delicate embossed pattern using a pipe making machine.

In connection with the present invention, when an embossed pipe is manufactured by a pipe making machine using an embossed metal plate, it takes a long time to complete the pipe, and an unexpected problem arises. Therefore, we solved these problems one by one and finally achieved the completed embossed metal pipe.

One of the above-mentioned problems is that when a metal flat plate is passed through a pipe making machine, a high-pressure male-female meshing curved surface is formed on the metal plate in the process of passing between the male-female meshing curved rollers installed horizontally and vertically. Roller pressure acts to form a curved surface while causing plastic deformation.
On the other hand, in the case of the embossed metal plate, the embossed pattern has an apparent volume equivalent to twice the thickness of the metal plate before the embossing due to the molding of the embossed pattern.

As a specific example, if a metal plate of 0.5 mm and 1 mm before embossing is used, a space is formed while the height from the protruding portion of the embossed pattern to the bottom surface is 1 mm and 2 mm. When manufacturing an embossed metal pipe using a metal plate, the embossed metal plate cannot maintain the original shape of the embossed pattern during the process of passing through the meshing male and female rollers of the pipe making machine and easily collapses. , It is necessary to accurately adjust the gap between the meshing circular male and female rollers according to the degree of embossing.

Further, when the gap between the meshing circular male and female rollers is narrow and the pressure is high, the deformation of the embossed pattern increases, and at the same time, the width of the embossed metal plate becomes wide. May overlap, and if the gap adjustment becomes wide, the curved surface cannot be smoothly achieved.

Another problem lies in the seams formed in the length direction of the embossed metal pipe. That is, when an embossed pipe is manufactured from an embossed metal plate using a pipe making machine, there is a problem that it is practically impossible to weld a seam formed in the length direction of the embossed pipe.
The present invention is a means capable of solving the above-mentioned problems, and relates to an embossed mold roller for meshing yin-yang engraving for manufacturing an embossed metal pipe.
To summarize the above contents,

When manufacturing embossed pipes with a pipe making machine, when an embossed metal plate or embossed metal band treated with an embossed roller, which has very accurate dimensional stability, is passed through the pipe making machine, it is used for curved surface formation. In the process of passing through a horizontal male-female meshing roller made of high-strength metal material and a symmetrical roller that meshes horizontally and vertically to form a pipe into a circle, the embossed pattern on the embossed metal plate that has become relatively thin due to the embossing process is deformed. There is a difference in the height of the embossed pattern, and in the length direction, the length of the embossed pattern in the length direction varies due to the difference in the pressing force due to the meshing of the rollers and the difference in the rotational shearing force, and the welded parts are different from each other. Welding was not possible due to loosening and misalignment in the height and length of the corresponding embossed handle.

Even if welding is performed, innumerable gaps and fine holes are formed in the weld seam, and the watertightness and airtightness of the seam cannot be ensured. Since it contaminates the surface of the embossed pattern, it loses its value as a commercial product.

A means for solving such a problem is a yin-yang engraved mold roller having a mutual meshing structure used for manufacturing an embossed metal pipe, which is presented in the present invention.

An example in which the yin-yang engraved mold roller 1 having a mutual meshing structure according to Examples 5 and 6 is composed of an embossing pattern different from that of the yin-yang embossed mold roller 1 presented in Examples 1 to 4. show.

As shown in FIG. 7, the yin-yang embossed mold roller 1 according to the fifth embodiment has substantially the same structure as the yin-yang embossed mold roller 1 according to the second embodiment, except that the embossing pattern is different. ..

As shown in FIG. 8, the yin-yang embossed mold roller 1 according to the sixth embodiment has substantially the same structure as the yin-yang embossed mold roller 1 according to the fourth embodiment, except that the embossing pattern is different. ..

Hereinafter, the configuration of each part constituting the yin-yang embossed mold roller 1 having the mutual meshing structure disclosed in Examples 1 to 6 will be described more specifically.

The yin-yang engraving mold roller 1 disclosed in Examples 1 to 6 is configured such that the upper roller 10 and the lower roller 20 of a high-strength metal material mesh with each other and rotate.

On the surfaces of the upper roller 10 and the lower roller 20, a pattern forming the positive embossed pattern portion 103 and the negative embossed pattern portion 203 is formed, and the positive embossed pattern portion 103 and the negative embossed pattern portion 203 are mutually formed. Formed to mesh.

Here, the pattern directly affects the aesthetics of the embossed metal plate formed by mixing the pattern itself and the volume feeling due to the yin and yang engraving. At this time, the pattern can be set according to preference.

As a concrete example
The embossed pattern portions 103 and 203 shown in FIGS. 2 to 6 have a long rectangular handle with rounded ends forming a pattern.
In the embossed pattern portions 103 and 203 shown in FIGS. 7 and 8, a handle having a quadrangular pyramid-shaped protruding portion forms a pattern.

The yin-yang embossed mold roller 1 according to Examples 1 and 3 shown in FIGS. 2, 3 and 5, and the second, fourth, and fourth examples shown in FIGS. 4, 6, 7, and 8. The difference between the Yin-Yang embossed mold roller 1 according to the fifth and sixth embodiments is the presence or absence of the narrow band-shaped groove 104 and the narrow band-shaped protrusion 204 formed on the upper roller 10 and the lower roller 20.

The strip-shaped groove portion 104 and the strip-shaped protrusion 204 are configured to mesh with each other and rotate when the upper roller 10 and the lower roller 20 rotate with the metal plate sandwiched between them. It means that the strip-shaped protrusion 204 intrudes and rotates while pushing the metal plate toward the groove 104.

The narrow band-shaped groove 104 and the narrow band-shaped protrusion 204 formed in this way partition the pattern having the embossed pattern along the circumferential surface at regular intervals, and the narrow groove 104 thus partitioned is embossed. A decorative effect can be given along with the pattern.

As shown in FIGS. 2 to 10, the main configuration of the yin-yang embossed mold roller 1 having the mutual meshing structure according to the present invention is the first left and right sides formed on both ends of the upper roller 10 and the lower roller 20. It is located at the ends 105, 106 and the second left and right ends 205, 206.

The importance of the first left / right end portions 105, 106 and the second left / right end portions 205, 206 is to solve the welding problem that occurs when manufacturing an embossed pipe using an embossed metal plate. ..

That is, the first left / right end portions 105, 106 and the second left / right end portions 205, 206 formed on both side ends of the yin-yang engraved mold roller 1 are both side surfaces of the embossed metal plate. By forming a small flat surface on the embossed pipe, the uneven embossed pattern formed on the embossed metal plate is deformed or the embossed pattern formed on the embossed metal plate is deformed when the embossed pipe is manufactured by using a conventional pipe making machine for manufacturing a smooth metal pipe. It is possible to solve the problem that welding becomes impossible due to the mismatch of the uneven embossed patterns formed at the seams in the length direction.
Further, the main technical configuration is an inclined surface structure at both ends of the metal plate to be put into the yin-yang engraved mold roller 1.
Such an inclined surface is processed at the same time as the flat metal plate is put into the yin-yang engraving mold roller 1 and embossed.

As shown in FIGS. 9 and 12, even if both side surfaces of the flat metal plate are not inclined surfaces, the embossed metal plate is formed by the first left / right end portions 105, 106 and the second left / right end portions 205, 206. A narrow flat surface is formed on both side surfaces of the above, and when the embossed metal plate thus formed is curved and circularized by a pipe making machine and the both side surfaces come into contact with each other, the both side surfaces are due to the difference between the inner diameter and the outer diameter. A V-shaped groove is naturally formed at the point where the metal plates come into contact with each other, but the width of the V-shaped groove may be very narrow depending on the thickness of the flat metal plate. This facilitates melt fusion by welding and enables solid and clean welding.

As shown in FIGS. 10 and 13, a metal plate that has not been processed so that both ends form an inclined surface is put into the yin-yang engraved mold roller 1 to manufacture an embossed metal plate having both ends having an inclined surface.
11 and 14 show an embossed metal plate having inclined surfaces at both ends manufactured through such a process.

At this time, as shown in FIGS. 10 and 13, a configuration that enables both ends of the metal plate to be embossed at the same time as the embossing process of the metal plate using the yin-yang engraving die roller 1 is formed on both side surfaces of the upper roller 10. The left and right inclined surface forming portions 107 and 108.

Then, the left / right inclined surface forming portions 107 and 108 form an internal angle (θ1) of 110 ° to 135 ° with the left / right end portions 105 and 106, whereby the left / right inclined surface forming portions 107 and 108 form the left / right inclined surface forming portions 107 and 108. The inclined surfaces at both ends of the formed metal plate are in contact with each other to form a welded seam 109 having a V-shaped groove 109a, and the V-shaped groove 109a has an internal angle (θ2) of 20 ° to 90 °.

In this way, by forming inclined surfaces at both ends of the metal plate at the time of manufacturing the embossed metal plate, a circular pipe is formed through the curved surface of the pipe making machine and the circularized roller, and the inclined surface and the inclined surface of the narrow plane are formed. Abut to form a narrow V-shaped groove 109a, and the V-shaped groove 109a thus formed is welded by melting and fusing the material itself so as to form the same weld seam 109 as the groove 104. As a result, the welded seam portion 109 and the groove portion 104 play a role of improving the aesthetic appearance together with the pattern by forming a kind of pattern.
The groove portion 104 and the welded seam portion 109 have a small width, and more specifically, have a width of 1.6 mm or less.

Then, in order to maintain the same width of the groove portion 104 and the weld seam portion 109, the width L1 of the first left and right end portions 105 and 106 formed at both side ends of the upper roller 10 according to the present invention is the groove portion. The width L2 of 104 is maintained at half the length.
That is, the length of the total width of the first left end portion 105 and the first right end portion 106 is the same as the length of the total width of the groove portion 104.

FIG. 15 is an example diagram schematically showing a cross section on the side of an embossed metal pipe manufactured by using an embossed metal plate manufactured by an embossed mold roller according to the present invention. FIG. 17 is a side sectional view showing various forms of the welded seam formed in the embossed metal pipe of FIG.

As shown in FIG. 15, the embossed metal pipe manufactured by putting the embossed metal plate manufactured by using the yin-yang engraved mold roller 1 of the present invention into a pipe making machine has a welded seam 109 in the length direction. Is formed, and a narrow V-shaped groove 109a is formed in the welded seam 109, and one or more are formed on the circumferential surface of the roller at regular intervals by welding the V-shaped groove 109a by melting and fusing the material itself. The same seam groove as the formed partition groove is formed.

As a result, the welded seam 109 formed in the length direction of the embossed metal pipe is integrally connected by clean and elaborate welding and at the same time forms a seam groove, together with other partition grooves for partitioning the embossed pattern. It has the advantage of being able to give a decorative effect by demonstrating a design aesthetic.

FIG. 16 is a diagram showing a state after welding the V-shaped groove 109a of the embossed metal pipe shown in FIG.

FIG. 17 shows various modified forms of the weld seam 109 of the embodiment shown in FIG. In addition to the form shown in FIG. 17, it is clear that various forms of the weld seam 109 including the V-shaped groove may be presented.

The feature of the welded seam portion 109 is that the central portion of the side cross section forms a'V'-shaped structure by forming the inclined surfaces at both ends of the metal plate by the left and right inclined surface forming portions 107 and 108. The'V'-shaped structure can be made the same to diversify its peripheral morphology.

The yin-yang engraved mold roller according to the present invention can give a much more elaborate and delicate embossed pattern than the conventional embossed pattern by a mechanical device for embossing on a smooth-faced pipe, and a pipe-making machine is used. In the production of embossed pipes, the embossed metal plate formed by the meshing embossed rollers in the embossed pipe enables welding during the production of the embossed metal pipe, and the welded part is formed by forming a narrow seam groove in the welded seam. By designing one or more circumferential grooves that do not appear outside and are the same as the narrow seam groove, along with the narrow seam groove, it is possible to improve the decorative effect with an elaborate embossed pattern, and it can be used industrially. The sex is great.
