Description
Technical Field
The present invention relates to a device for providing jewelry with chains and/or ropes.
Background
Devices provided with multiple tools are currently used to provide chains and ropes for jewelry to perform a variety of movement and processing steps starting from a base metal wire.
For example, a metal wire is generally introduced into the apparatus and continuously operated by the tool, such as:
feeding the cutting assembly by means of an advancing roller,
-performing the cutting by means of a cutting assembly,
deforming by means of a forming clamp to form a link,
-moving the chain links by means of pliers,
linking the links to the previously provided links by means of forming jigs and pins,
-and the like.
In such devices, typically all tool movement is controlled by one or two motors that transmit motion to the various tools through a cam shaft, wherein each cam is kinematically connected to the respective tool through a lever system and imparts motion thereto as a result of rotation of the shaft.
This background art has some drawbacks.
First, in the known type of apparatus, a time-consuming and inconvenient calibration operation, in particular of the cams, is required before starting the machining in order to check/set the correct movements of the various tools.
In fact, the cams must be positioned precisely to ensure correct and timely movement of the tool during machining.
Furthermore, in the known type of equipment, when the machining must be changed to provide a different type of chain/rope, it is necessary to replace one or more cams with other cams of suitable dimensions in order to impart the correct movement to the respective tool in order to perform the operations required to obtain the desired type and size of chain/rope.
This requires long machine downtime and time consuming and awkward operations, as well as the use of cams of different shapes/sizes depending on the type of product desired.

It is a further object of the present invention to provide a device for providing jewelry with chains and/or ropes that allows to change the type of machining while significantly reducing the machine downtime with respect to similar devices of known type.
It is a further object of the present invention to provide an apparatus for providing jewelry with chains and/or ropes that does not require cams for moving various tools, or at least does not require replacement of cams to change from one type of machining to another.
It is a further object of the present invention to overcome the disadvantages of the background art in a way that can replace any existing solutions.
The main object of the present invention is to provide a device for providing jewelry with chains and/or ropes that is highly reliable, relatively easy to provide and cost competitive.
