Jewelry Mandrel Pliers and Method of Using Same

摘要

The present invention provides a mandrel tool and method for more efficiently and consistently forming various shapes of material. In one embodiment of the invention, a pair of pliers having mandrel jaws that are shaped with a uniform cross sectional area throughout a length of the mandrel jaw is used to replace the traditional tapered mandrel. Because the mandrel jaws have a uniform cross sectional area, the wire, for example, can be wrapped multiple times around the mandrel jaw when it is desired to produce multiples of the same shape. For added versatility, the pliers can have opposing mandrel jaws, with different size cross sectional area.

主权项

1. A pair of mandrel pliers for forming metal during the manufacture of jewelry, said mandrel pliers comprising:
a first member having a first handle on a first proximal end of said first member and a first mandrel jaw on a first distal end of said first member; a second member having a second handle on a second proximal end of said second member and a second mandrel jaw on a second distal end of said second member; wherein said first member and said second member are attached at a connection point that divides the first member into the first proximal end and the first distal end, and divides the second member into the second proximal end and the second distal end; wherein the first distal end and the second distal end comprise a distal length measured from the connection point to a terminal location at an end of the first and second distal ends; wherein the first mandrel jaw extends almost entirely the distal length; wherein the second mandrel jaw extends almost entirely the distal length; wherein the connection point permits pivoting movement between said first mandrel jaw and said second mandrel jaw such that said first mandrel jaw and said second mandrel jaw are opposed and adapted for moving coplanarly with respect to each other in response to a squeezing force being applied to said first handle and said second handle, wherein said first mandrel jaw has a first uniform cross-sectional area throughout its length and wherein said second mandrel jaw has a second uniform cross-sectional area throughout its length, and wherein said first mandrel jaw and said second mandrel jaw are capable of securely gripping a material placed there between upon the application of said squeezing force to said first handle and said second handle by a user; and wherein the first uniform cross-sectional area has a geometric shape.
