Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative tube whose outer surface has been subjected to a decorative treatment such as polishing or plating.

[0002]

2. Description of the Related Art For example, when a handrail provided in a house has a pipe structure, a viewpoint from the viewpoint of use such as aesthetics and tactile sensibility, and a viewpoint from the viewpoint of manufacturing cost reduction by omitting a painting operation. For this reason, it is common to use a decorative tube in which the outer surface of a metal tube such as a steel tube or an aluminum tube has been subjected to a decorative treatment such as polishing or plating in advance.

[0003]

By the way, the metal tube is
It is sold in the form of a straight tube of a predetermined length. Therefore, when manufacturing a workpiece having a required shape and structure using the metal tube as a material, the maker uses the metal tube in this sales form, and performs various processes such as cutting, drilling, bending, and welding on the metal tube. To produce the required workpiece.

[0004] Among these various processes, for example, a plurality of holes are formed at predetermined intervals on an outer surface of a metal tube for primary processing cut to a required length along a straight line parallel to its axis. In processing, it is necessary to make a marking on the outer surface of the metal tube to indicate the position of the hole. In this case, if the metal tube is a decorative tube, the outer surface thereof is exposed to the public as it is as a product surface, so it cannot be engraved on the outer surface. Marking is performed using a marking material that can be erased, and the marking is wiped and erased with a solvent in the final stage of production.

However, at the time of this marking, each of the plurality of perforated positions is located on the straight line (in other words, each of the plurality of perforated positions is located at the same position in the circumferential direction of the metal tube). As described above), it is necessary to perform positioning in the circumferential direction of the metal tube and to determine a drilling interval by measuring a dimension in an axial direction, and there is a problem that work is complicated and workability is poor. Along with the demand for simplification, there is also a demand for facilitating post-marking erasure work.

On the other hand, for example, when a substantially L-shaped workpiece is manufactured by welding, the two metal pipes cut at a predetermined angle are brought into contact with each other and welded to each other. If the positioning of one metal tube and the other metal tube in the circumferential direction is not accurate, even if the cutting angle is accurate, the butt joint will be misaligned and the value as a product will be impaired. Become. For this reason, in such a welding process, it takes time to position the two metal tubes in the circumferential direction, which is one of the causes of a reduction in workability, and there is a demand for simplification of the positioning operation at the time of such welding.

[0007] In addition, in general, when bending a metal tube, not only a decorative tube, if the metal tube to be processed is a seamless tube such as a drawn tube, there is no problem. In the case of a pipe (most of the general structural steel pipes are ERW pipes), a problem occurs depending on the bending direction.
That is, in the ERW pipe, there is an ERW weld extending in the axial direction on a part of the pipe wall, and the ERW weld has a hard and brittle structure that is altered by welding heat. ,
From the viewpoint of minimizing the extension deformation and the shrinkage deformation in the ERW weld, the center line of the ERW weld and the center line of the bend match (in other words, the ERW weld is bent in the bending direction). It is necessary to position the metal tube in the circumferential direction (so that it is positioned in a direction perpendicular to the plane including the surface). However, it takes a long time to position the metal tube in the circumferential direction, which causes a reduction in workability. There is also a demand for simplification of the positioning work accompanying the processing.

Further, in general, not only a decorative tube but also a metal tube, its sectional shape and outer dimensions can be determined relatively easily by visual inspection or touch, but the standard thickness is set in small increments. For this reason, it is difficult to judge by visual inspection and the like.Therefore, when selecting a metal tube as a material, each time the operator measures the wall thickness, it takes time and effort to select the material. Therefore, there is a demand for easy material selection.

Accordingly, the present invention has been made to provide a cosmetic tube having good workability during processing.

[0010]

According to the present invention, as a specific means for solving the above-mentioned problem, a straight pipe having a circular cross section whose outer surface 1a has been subjected to a decorative treatment such as polishing or plating. In the cosmetic tube 1, an adhesive tape 3 is attached on the outer surface 1a of the cosmetic tube 1 in the tube length direction, and the surface 3a of the adhesive tape 3 is attached to the cosmetic tube 1 in a state of being attached to the cosmetic tube 1. It is characterized in that a reference line L extending in the tube length direction is provided in parallel with the axis of the decorative tube 1.

[0011]

According to the present invention, the adhesive tape 3 is attached to the outer surface 1a of the decorative tube 1 which is a straight tube having a circular cross section in the lengthwise direction of the tube, and is attached to the surface 3a of the adhesive tape 3. Is provided with a reference line L extending in the tube length direction in parallel with the axis of the cosmetic tube 1 in a state of being attached to the cosmetic tube 1. In the case of marking on the surface 1a at predetermined intervals in a direction parallel to the axis thereof, the operator may simply mark on the reference line L while measuring the dimension in the pipe length direction. Compared to the conventional case where it is necessary to check both the position in the circumferential direction and the position in the tube length direction when marking the decorative tube 1, the marking operation is greatly simplified and the workability is improved. Good and That.

Further, for example, in a case where the tube ends of two decorative tubes 1 and 1 whose tube ends are cut at a predetermined angle are joined to each other to produce a substantially L-shaped workpiece by welding, The cutting line is determined based on the reference line L at the time of cutting the tube end, and the cutting is performed according to the reference line L. When the tube ends are abutted with each other, the reference line L of one cosmetic tube 1 and the reference line of the other cosmetic tube 1 are used. L is visually recognized and matched, so that the positioning of the two decorative tubes 1 and 1 in the circumferential direction is easily and reliably performed. Is reliably prevented, the workability in the joining operation is improved, and the reliability of the obtained product is also improved.

Further, when the decorative tube 1 is bent, for example, even if the decorative tube 1 is an electric resistance welded tube having an electric resistance welded portion on its pipe wall, the electric resistance welded portion and the reference Based on a relative relationship between a relative position in the circumferential direction of the decorative tube with respect to the line L and a position of the reference line L in a state where the decorative tube 1 is set in the bending device, the center line of the ERW weld is bent. It can be easily and reliably positioned at a position orthogonal to the plane including the flat surface, and the workability in bending is improved.

On the other hand, the reference line L is
Is attached to the surface 3a of the adhesive tape 3 affixed on the outer surface 1a, so that after the completion of the working operation, the adhesive tape 3 is peeled off, so that the reference line L is connected to the decorative tube 1.
Can be easily removed from the outer surface 1a of the cosmetic tube 1, for example, the reference line L is directly provided on the outer surface 1a of the decorative tube 1,
Compared to the case of wiping and erasing this using a solvent,
Post-work is simplified, and further improvement in workability can be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on embodiments shown in the accompanying drawings.

FIG. 1 shows a cosmetic tube 1 according to an embodiment of the present invention. This decorative tube 1 is made of a stainless steel electric resistance welded tube having a circular cross section as a base material, and the outer surface of the electric resistance welded tube is polished as a cosmetic treatment. The wall has an electric resistance weld 2 extending in a direction parallel to its axis.

The decorative tube 1 has a straight tube shape cut to a prescribed tube length, and is shipped and sold in this shape. Therefore, a user who intends to manufacture a required workpiece using the decorative tube 1 cuts the decorative tube 1 in accordance with the size, shape, and the like of the target workpiece, and drills holes required for the purpose. Various processes such as processing and welding are performed. From the viewpoint of enhancing the workability of the user in the processing operation, the decorative tube 1 is provided with the following reference line L used as a processing reference by applying the present invention.

The reference line L corresponds to the outer surface 1 of the decorative tube 1.
In one embodiment, the reference line L is provided by printing or the like in the center of the surface 3a in the width direction. This is realized by attaching an adhesive tape 3 with a reference line to the outer surface 1a of the cosmetic tube 1. In addition, when the adhesive tape 3 is applied, as shown in FIGS. 1 and 5, the adhesive tape 3 and the ERW portion 2 are located at opposing positions with the axis of the decorative tube 1 interposed therebetween. The bonding position of the adhesive tape 3 is set relatively to the electric resistance welded portion 2.

In this embodiment, not only is the adhesive tape 3 provided with the reference line L,
In addition, a predetermined information display M is provided. The information display M is information on the cosmetic tube 1, that is, information that can be a determining factor when the cosmetic tube 1 is selected for a desired purpose. , External dimensions and thickness are displayed as character information. The information display M is not limited to the character information as in this embodiment. For example, the material color of the decorative tube 1 or the line color of the reference line L It is also possible to select and set the information in accordance with information such as dimensions and thickness, and to display the information as color information.

As described above, since the reference line L is provided on the outer surface 1a of the decorative tube 1, the decorative tube 1 is used and various processes are performed thereon to produce a desired workpiece. In this case, the following specific advantages can be obtained.

First Working Example FIG. 3 shows a first working example in which two decorative tubes 1 and 1 are butted at a predetermined angle and are joined by welding to form a substantially L-shaped bent. The case where a workpiece having a form is manufactured is shown.

At the time of welding in this manufacturing operation, the tube ends 1b, 2 of the two decorative tubes 1, 1 which are joined to each other.
1b are cut obliquely at a predetermined angle, and at this time, the reference line L is positioned in a direction perpendicular to a plane including the center line of the bending (in the example of FIG. 3, a plane parallel to the paper). The cosmetic tube 1 is positioned in the circumferential direction and cut.

Thereafter, the tube ends 1b, 1b of the two decorative tubes 1, 1 cut on the basis of the above-mentioned reference line L abut each other as shown by a dashed line in FIG. By matching the reference line L of the makeup tube 1 with the reference line L of the other makeup tube 1, the tube ends 1b, 1b of the two makeup tubes 1, 1 do not shift in the circumferential direction. Accurate abutment is performed, and the quality (shape and quality of weld strength) of the welded portion when this is welded is improved.

As described above, the reference line L attached to the decorative tube 1 is used as a reference when the decorative tube 1 is cut and when the two decorative tubes 1 and 1 are joined. Positioning in the work is performed easily and reliably, and workability in the joining work is improved accordingly.

On the other hand, after the joining operation is completed,
It is necessary to remove the reference line L and expose the entire decorative surface of the decorative tube 1 to ensure its aesthetic appearance. In this case, the reference line L is connected to the adhesive tape 3 as in this embodiment. By adopting the structure attached to the front surface 3a, the removal of the reference line L can be achieved simply by peeling the adhesive tape 3, and the removal operation is easier than, for example, wiping using a solvent. It is simple and can be expected to further improve workability.

Further, at the time of joining, it is necessary to select the decorative tube 1 to be used from among various types of decorative tubes. In this case, the information display M attached to the adhesive tape 3 is required. By visually recognizing, the operator can easily and reliably select a desired makeup tube.

Second Working Example FIGS. 4 and 5 show a bending process of the decorative tube 1. FIG.
In this bending process, the reference line L exerts its effect most when the decorative tube 1 is formed of an electric resistance welded tube. That is, when the decorative tube 1 is formed of an electric resistance welded tube, since the electric resistance welded portion 2 is present in the decorative tube 1, the extension deformation and the contraction deformation accompanying the bending work are caused by the electric resistance welded tube. So that it is the least in the weld 2
It is necessary to set the bending direction of the decorative tube 1 (i.e., the circumferential set position of the decorative tube 1 in the bending device).

In such a case, for example, in this embodiment, since the electric resistance welded portion 2 and the reference line L are located at positions facing each other across the axis of the decorative tube 1, FIG.
As shown in (1), positioning of the cosmetic tube 1 in the circumferential direction is performed such that the reference line L is located in a direction orthogonal to a plane including the bending center line (a plane parallel to the paper surface in the example of FIG. 4). Thus, the reference line L can be made to correspond to the bending center line.

As described above, when the decorative tube 1 is bent, the reference line L is used as a reference for setting the decorative tube 1, so that the positioning operation of the decorative tube 1 becomes easy and accurate. Workability can be improved.

Third Processing Example FIGS. 6 and 7 show a marking operation in the case where holes are made in the tube wall of the decorative tube 1 at predetermined intervals along a straight line parallel to the axis of the tube.

In this case, while measuring the dimension in the length direction of the pipe, the operator simply attaches the position lines N, N,... Complete.

That is, in this embodiment, since the reference line L is provided, it is not necessary to confirm the circumferential position of the cosmetic tube 1 at each drilling position each time. Work is facilitated, and as a result, workability in drilling is improved.

In this case, the position line N is applied only to the front surface 3a of the adhesive tape 3 so that the adhesive tape 3 is peeled off and the reference line L is removed. ,... Are also removed, the position lines N,
It is not necessary to remove only N,.

Others (1) In the above embodiment, the case where the decorative tube 1 is made of a stainless steel tube as a base material has been described as an example. However, the present invention is not limited to such a structure, and the present invention is widely applied to metal tubes in general. For example, the decorative tube 1 can be formed using a structural steel tube, an aluminum tube, or the like as a base material.

(2) In the above embodiment, the case where the decorative tube 1 is constituted by an electric resistance welded tube having a circular sectional shape is described as an example, but the present invention is limited to such a structure. However, it goes without saying that the present invention is applicable to, for example, a case where the cosmetic tube 1 is formed of a square tube, or a case where the cosmetic tube 1 is formed of a seamless tube such as a drawn tube.

(3) In the above embodiment, the case where the decorative tube 1 is made by polishing is described as an example. However, the present invention is not limited to such a configuration. The present invention can also be applied to a product made by another makeup process.

(4) In the above embodiment, an example is described in which the cosmetic tube 1 is provided with only one reference line L. However, the present invention is not limited to such a configuration. For example, a plurality of the reference lines L may be provided.
