RING SIZING TOOL
20190329338 · 2019-10-31 ·

A ring sizing tool with a base and a guide movably coupled to the base. The base has first and second ends with a longitudinal axis extending between the ends. A cut guide surface is positioned adjacent the second end, and a base ring engaging surface is spaced apart from the cut guide surface. The guide has a guide ring engaging surface and at least one ring size indication spaced apart from the guide ring engaging surface. The guide is movable with respect to the base in a direction aligned with the longitudinal axis of the base between at least a first position, in which the guide ring engaging surface abuts the base ring engaging surface, and a second position, in which the guide ring engaging surface is spaced a distance from the base ring engaging surface. A method for sizing a ring with the ring sizing tool.

JEWELRY MANDREL PLIERS AND METHOD OF USING SAME
20190255681 · 2019-08-22 ·

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.

Die cutter holding and lifting systems, apparatuses, and methods are disclosed for use with custom and commercially available die cutters. According to some examples, a system includes a base, a separation assembly, and an actuation assembly. A separation assembly can be coupled to the die cutter, and the die cutter in combination with the separation assembly can be coupled to the base, such that the actuation assembly can be utilized to cause a separation of die plates of the die cutter for increased productivity in cutting, stamping, or pressing operations involving die cutters.

Press for forming jewelry from silverware

A workpiece bending press has a vertical ram with a lateral through-hole near the bottom. A first elongated mandrel has an end that mounts in the through-hole. The first mandrel mounting end has a cavity that receives an end of a second mandrel. The first mandrel then extends from a first side of the ram, and the second mandrel extends from the opposite side of the ram. Workpiece forming blocks may be placed under each mandrel, providing two different mandrels and forming blocks on the ram at once for different pressing stages or different workpiece diameters. One or both mandrels may be part of a set of interchangeable mandrels with different outer diameters. The ram may be operated by a lever that is quickly movable to the left or right side of the press for convenient use of mandrels extending from the left and right sides of the ram.
