how to make a ring using a hydraulic press

Presses are one of the most efficient, productive metal shaping and deforming methods available, easily adapting to fit any production and assembly operation by changing die, pressure and process position settings.

Meet instructor Melissa Muir and begin by exploring the essentials, using a pancake die to craft beautiful earrings. After that, explore additional riveting options as you form custom shapes and pierce your designs for unique looks.

Basics

A hydraulic press is a machine that utilizes Pascal's Principle to produce force. It consists of two interconnected cylinders: a smaller slave cylinder and larger master cylinder filled with hydraulic fluid; with one of the latter housing a piston used to apply pressure; force applied against this piston transfers hydraulic fluid from its host slave cylinder into its master counterpart and generates high levels of pressure to crush whatever is in between its Plunger and Ram.

A hydraulic press can be utilized for numerous metal-forming processes. It is capable of forging, clinching, molding, blanking, drawing, punching, coining, piercing and coining metal; shaping plastics; as well as providing sample preparation services for XRF analysis.

There are various types of hydraulic presses, such as C-frame, welding frame, four column free forging hydraulic press and multi layer steel strip winding hydraulic press. Their main distinction lies in how their forces exerted.

C-frame hydraulic presses exert force from both ends of their frame. This force travels down through a movable beam before being distributed by the ram to workbenches. The direction and magnitude of force can be altered via this mechanism; plus it also controls how much pressure is applied on workbenches.

Hydraulic presses are one of the key tools in any jewelry maker's toolbox, serving both to create beautiful pieces such as rings and bracelets as well as perform other metal-forming processes like forming flat wire into circles or bending and shaping sheet metal sheets.

Rio Grande presents this video which will show how to use blanking dies with a hydraulic press to quickly and efficiently create bracelet and ring blanks, including how to hand form them into finished rings, along with safety tips when operating the press. Watching this video is essential if you want to learn how to operate one!

Materials

Hydraulic presses are machines used to apply significant compressive force. They use a slave cylinder connected by piston to the master cylinder under hydraulic fluid pressure; this system allows users to bend, draw, punch, coin, form, shape or bend metal workpieces with ease and speed. They're often employed by manufacturers producing mass amounts of metal products for commercial or industrial use.

Hydraulic presses are not only simple to operate, but they're also highly versatile, suitable for a range of applications and cost-effective alternatives to traditional machining tools that require specialization and struggle with high production orders. Furthermore, hydraulic presses can accommodate high pressure deformation applications.

Hydraulic presses can be an ideal tool to forge metal into shapes such as rings. In this process, sheets of metal are placed between two dies before the ram lowers to apply a substantial force to blanking material - the result being metal being compressed into its desired form and design by pressing.

Starting ring manufacturing using a hydraulic press requires various materials. A blanking ring made of coil, sheet or strip metal must first be formed into place - this allows control of metal movement during deformation while matching mold dimensions exactly.

After press-forming metal into its final shape, impression dies must also be created that are capable of holding it - usually composed of either masonite, cast metal, or pourable epoxy-steel - in their place until use. The type of die chosen depends on both size of ring to be created as well as materials required.

Jewelers use simple tools and a hydraulic press to add depth and dimension to metal pieces. In this online workshop led by Richard Sweetman, the hydraulic press is put through its paces by coaxing flat sheet metal into three-dimensional masterpieces. Richard first shows proper operation and techniques for working with one before proceeding onto show how many techniques exist that demonstrate its powerful use.

Tools

The hydraulic press is an amazing mechanical marvel that makes manipulating metal into three-dimensional forms easier than ever before. Metalsmith Richard Sweetman uses his hydraulic press in this online workshop to showcase just how versatile it can be, creating bracelets, rings and earrings as well as lidded containers - including covering safety measures before diving deeper into ways it can add character to jewelry designs.

Example techniques taught include using a pancake die to form stylish curved earrings and silhouette dies for creating chic pierced pendant forms. He also discusses anticlastic and synclastic forming techniques and fold-forming blanks into gorgeous bracelets and pendants.

To create rings using the hydraulic press, a special ring die and several other tools are essential. Richard uses an old inner tube that has been cut into inserts to craft his die and achieve an elegant doming effect as he presses metal through. He also provides details on sizing the die and how to anneal metal before placing it inside it.

Once your ring die is in place, use rubber inserts on the platen of the hydraulic press to add depth when pressing your piece. Richard recommends adding up to four rubber inserts per depth requirement; add two or three as necessary. Even without using a die, this method still allows you to make rings by placing metal onto its platen and cranking down with a handle handle.

To build a frame for your hydraulic press, there are two methods available. Either welding a piece of pipe to the platen, or creating a bolt-together model. For the latter option, drill four holes in both top and bottom threaded stock. Cut an enough pipe length from this hole at the top of platen down to bottom hydraulic ram.

Techniques

Hydraulic presses utilize pumps to generate and maintain pressure in metal dies. Hydraulic presses can be used for an assortment of tasks, including forging, stamping, cold extrusion, bending, flanging, sheet drawing powder metallurgy pressing. They may also be utilized in metal fabrication applications in which precision and accuracy is essential - the hydraulic press being an adaptable machine which can be tailored specifically for individual projects.

Beginners may find hydraulic presses intimidating; but with guidance and practice, they can become invaluable tools in their metalsmithing workshop. Join renowned instructor Melissa Muir as she covers the fundamentals of using one and shows you how to make elegant earrings, pendants and bracelets using it. You will learn essential operations and guidelines that ensure safe operation of your press; additionally discover custom form formation techniques as well as riveting options for eye-catching multilayered pieces.

Richard provides valuable guidance and instruction to customize and manipulate pressed forms with additional techniques, as well as offering solutions to common issues and inspiring design concepts that will allow you to get the most from your hydraulic press.

No matter your level of experience, hydraulic presses are invaluable tools that can take jewelry making to a whole new level. With some effort and determination, you can transform your workshop into an efficient production center.

Hydraulic presses have been around for quite some time and can be found in various industries. Hydraulic presses are often employed by military units for loading ammunition, among other uses that require technically defined metal formed parts with exact tolerances. They're also frequently employed by manufacturers producing tracks, tires and other parts used by cars and commercial businesses alike.

Hydraulic presses can be purchased from various suppliers, or you can build one yourself for much less. To create one yourself, all that's required to create one is a sturdy metal frame into which a hydraulic ram will be installed and threaded cylinder that can be secured using nuts - as well as some additional tools and the construction process should go smoothly.
