This application claims priority under 35 USC § 119 to Application Serial No. IN 201941025661, filed in the Intellectual Property India on Jun. 27, 2019, the entire contents of which are hereby incorporated by reference.
Present disclosure generally relates to a field of manufacturing. Particularly, but not exclusively, the present disclosure relates to manufacturing of jewelery. Further, embodiments of the disclosure disclose a system and a method for manufacturing a hollow tubular jewelery, which is of ultra-light weight.
Jewelery is a decorative item, that people desire to wear. Jewelery is available in a variety of designs, sizes and usage of precious stones in the jewelery, increases the overall value of the jewelery. Also, jewelery is a form of status quotient for people wearing them. Jewelery items such as necklaces, rings, collets, earrings, bangles etc., increases fashion quotient of people wearing them. Generally, jewelery may be manufactured of precious natural metals such as gold, silver, platinum and the like. In addition to these metals, precious stones such as diamonds, ruby, pearl, emerald and the like are also used in the jewelery to increase aesthetic appearance and value of the jewelery.
With increase in demand for decorative jewelery lot of efforts have been made to develop and manufacture a jewelery which pleases the customer. Like clothing, trends in jewelery will also change with time. This calls for quick adaptability of manufacturing the jewelery based on the current trend. One such trend is ultralight jewels which has gained quite a lot of popularity. The concept of manufacturing ultralight jewelery is known in the art. The ultralight jewelery is composed of tubular structure, which provides the advantage of weight reduction when compared to the solid structure. The tubular structure or the tube may be extruded from a strip of metal and the tube may be formed to a required shape to manufacture a jewelery such as ring, bangle, and the like.
Conventional process of manufacturing the tubular jewelery may include steps of metallic tube extrusion, winding of metallic tube to give it a round structure (e.g. bangle), and forming perforations to improve the appeal. This may be followed by studding and fusing different parts to obtain a required shape. The jewelery may then be subjected for a finishing operation to improve the smoothness or to remove abrasions. Such a manufacturing process is limited to manufacturing of conventional shapes such as circular, square, triangular and the like. However, with the everchanging trend, manufacturing the jewelery with such conventional shapes may not be enough, as the customer may not like to see the same sort of design every time.
The present disclosure is directed to overcome one or more limitations stated above or any other limitation associated with the conventional arts.
The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
One or more shortcomings of conventional systems and process is overcome, and additional advantages are provided through the provision of the system and method for manufacturing ultra-light tubular jewelery as described in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure.

The concept of manufacturing ultra-light weight tubular jewelries with perforated is known in the art. However, such manufacturing process or method is limited to basic cross sections of the tubes such as round, square, oval, etc., leading to simple three dimensional tubes. However, with everchanging needs and trend, manufactures or makers of jewelers are coming out with ultralight jewels with unconventional cross-section like floral, star, lotus, etc. These unconventional cross-section may include angular surfaces and hence it may be difficult to perform further operations like forming perforations, etc.
The tubular jewelery with conventionally shaped cross sections can be easily perforated, without the any challenge. The present disclosure is directed to solve the problems associated with the conventional methods.
Accordingly, the present disclosure is directed to a system and method to manufacture unconventionally angled three-dimensional tubular jewelery, for promoting ultra-light weights. The system for manufacturing a hollow tubular jewelery includes a die and core assembly for extruding a hollow metallic tube, wherein a core is positioned within a die of the die and core assembly to define at least one of three-dimensional surfaces and curved surfaces of the hollow metallic tube. A mandrel is provided for bending the hollow metallic tube, wherein the mandrel is fixed proximal to the die and core assembly. The core is positioned perpendicular to top surface of the mandrel, and a tip of the core is positioned to be in contact with a central region of the mandrel. A laser source which is configured to emit a laser beam is provided to form perforations on a bent hollow metallic tube. The system also includes a fixture which is adapted to hold the bent hollow metallic tube. The fixture is configured to rotate and tilt to adjustably position the at least one three-dimensional surface and the curved surface of the bent hollow metallic tube perpendicular to the laser beam for forming the perforations.
Once the perforations are formed, the plurality of hollow metallic tubes may be subjected for fusing in a fusing station to form a fusion product assembly. Fusing the plurality of hollow metallic tubes comprises fixing a plurality of ornaments onto the perforated hollow metallic tube, and then fusing in one or more regions. Lastly, fused regions are given finishing by abrasive process. The system and method of the present disclosure thus helps in manufacturing the jewelery of unconventional shapes.
In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying figures that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
