Definitions

  • the present invention relates to an apparatus for providing chains and/or cables for jewelry.
  • Apparatuses provided with a plurality of tools are currently used for the provision of chains and cables for jewelry to perform the various steps of movement and processing starting from a basic metal wire.
  • a metal wire is introduced in the apparatus and is subjected to successive operations by said tools, such as, for example:
  • cams must be positioned precisely in order to ensure the correct and timely movement of the tools during machining.
  • the aim of the present invention is to provide an apparatus for providing chains for and/or cables jewelry that is capable of avoiding the drawbacks of the background art in one or more of the above aspects.
  • an object of the invention is to provide an apparatus for providing chains and/or cables for jewelry that allows much faster and easier operations for calibration of the various tools than similar apparatuses of the known type.
  • Another object of the invention is to provide an apparatus for providing chains and/or cables for jewelry that allows to change the type of machining while significantly reducing machine downtimes with respect to similar apparatus of the known type.
  • Another object of the invention is to provide an apparatus for providing chains and/or cables for jewelry that does not require cams for the movement of the various tools, or at least does not require their replacement to change from one type of machining to another.
  • a further object of the present invention is to overcome the drawbacks of the background art in a manner that is alternative to any existing solutions.
  • Not least object of the invention is to provide an apparatus for providing chains and/or cables for jewelry that is highly reliable, relatively easy to provide, and at competitive costs.
  • an apparatus for providing chains and/or cables for jewelry comprising at least the following assemblies:
  • an apparatus for providing chains and/or cables for jewelry is generally designated by the reference numeral 10.
  • the apparatus 10 comprises, in machining order, the following assemblies:
  • One of the particularities of the invention resides in that it comprises dedicated movement means for each of said assemblies 11, 12, 13, 14, 15.
  • the expression “dedicated movement means” means that the movement means are adapted to move only the tools belonging to the respective assembly.
  • the base wire feeding assembly 11 comprises a pair of rollers 16a, 16b, each moved by a respective first electric motor 17a, 17b.
  • the rollers 16a, 16b move simultaneously, but in opposite directions, to produce the advancement of the wire that runs between them along a first direction X.
  • the wire cutting assembly 12 comprises:
  • the translating blade moves to cut the wire to the desired size to provide a link.
  • the assembly 13 for forming a link comprises:
  • the wire cut by the assembly 12 is deformed by the assembly 13 by means of the action of clamps 25a, 25b, which bend it around the pin 24 to provide a link.
  • the assembly 14 for conveying said link comprises:
  • the pincer 28 can slide between:
  • the assembly 15 for forming a chain and/or cable comprises:
  • the links are linked to each other and a chain and/or cable is formed.
  • all the motors 17a, 17b, 18, 20, 22, 26, 29, 34, 37, 40, 42, 45, 47, 51, of the apparatus 10 are of the brushless type.
  • Such electronic controller is programmable and therefore, depending on the type of machining to be performed, it is sufficient to modify one or more of the instructions of the controller to change the movements of one or more tools of the assemblies 11, 12, 13, 14, and 15, as needed, without the need to physically intervene on the apparatus and significantly reducing machine downtimes with respect to similar apparatuses of the known type.
  • the invention achieves its intended aim and objects by providing an apparatus for providing chains and/or cables for jewelry that allows much faster and easier operations for calibrating the various tools than similar apparatuses of the known type.
  • an apparatus for providing chains and/or cables for jewelry which allows to change the type of machining while significantly reducing machine downtimes with respect to similar apparatuses of the known type.
  • an apparatus for providing chains and/or cables for jewelry which does not require cams for the movement of the various tools, or at least does not require their replacement for transition from one type of machining to another.
  • the materials used may be any according to the requirements and the state of the art.
