How to Make a Hydraulic Press for Jewelry Scale Projects

Hydraulic presses are one of the most versatile metal forming tools available, especially when applied to jewelry-scale projects. You can learn to form shapes using pancake dies and impression dies to add reliefs or relief patterns on metal surfaces.

Richard also shows an alternative method for pressing metal with a vise, as well as how to make rubber inserts for creating depth in pressed metal products.

How to Build a Hydraulic Press

Jewelers using a simple hydraulic press can create limited editions of hand wrought hollow forms without them looking machine made, something which would be difficult or impossible with traditional methods like raising, chasing and die-forming masonite dies.

Hydraulic presses provide jewelers with a tool for precisely bending thin or thick metal into three-dimensional forms quickly. Installing one in your jewelry studio increases productivity while decreasing production times - an invaluable addition to metalsmithing business operations.

Richard Sweetman offers this workshop to demonstrate how to create an affordable, durable hydraulic press that can be used for various metal forming purposes. In particular, it demonstrates how to create a professional-grade press that is suitable for various metal forming tasks; then teaches you how to use one for jewelry creation using pressing techniques such as embossing texture onto metal; rolling symmetrical shapes in pairs then joining them; manipulating curves and points into curves or points; creating texture by roller printing it, and adding dimension by creating textured surfaces or making pressed puffs - as well as more traditional metal forming methods such as embossing texture onto metal; rolling symmetrical shapes in pairs then joining them; manipulating metal into curves and points; manipulating metal into curves and points and manipulating metal into curves or points; creating texture by roller printinging, roller printing it and roller printing techniques such as embossing texture onto metal; embossing texture onto metal; rolling symmetrical shapes then joining them; manipulating metal into curves or points, manipulating curves or points, manipulating into curves or points, or creating texture by roller printing or roller printing techniques or by roller printing techniques such as rolling and joining pairs together followed by joining them; rolling them and joining them together before joining; manipulation by rolling pair after joining; manipulating curves or points or manipulating into curves and points or manipulating metal into curves or points, manipulation by roller printinging textures surface with roller printinging techniques while roller printinging metallic surfaces or roller printinging with roller printinging surface by roller printinging textures onto surface by manipulating metal into curves or points then manipulating metal into curves or creating textures on surfaces through roller printinging surface by roller printinging; roller printinging, then joining together creating texture onto surface and finally adding roller printinging texture onto surface creating roller printing then manipulating metal into curves then joining curves when manipulating curves or creating textures then manipulate into curves then curves then adding roller printinging then press puffing it, manipulating curves then manipulating curves creating texture creating textures textured surfaces creating texture on roller printing then creating surface creating roller printing, manipulating it all while rolling between or joining curves onto surfaces while adding textured surfaces then roller printing and adding depth while adding dimension textured surface printing onto texture onto metal manipulating curves finally creating textures on later later printing onto then manipulating then finally adding dimension then later with roller printing and points manipulation into curves and points onto creating curves and points later then manipulating curves then joining curves then points later on while roller printing then then curves then point then joining curves then pressing prints onto surfaces by rolling-printing it or simply pressing puffing then joining curves printing them roller printing onto it lastly, finally adding roller printing textured surface printing into curves then curves then printing then pressing then adding textures then roller printing surface roller printing then manipulating curves onto surfaces later, plus rolling then manipulating metal, manipulating curves then manipulating curves all whils rolling through then manipulating curves finally creating curves later adding dimensioning iting creating curves then manipulation using manipulation later using creating texture into curves later later using creating textures into curves then manipulating curves then points into curves onto then rolling prints then finally adding texture roller printing then points create curves before then eventually using roller printing then points into curves later and finally to finally finally to curves then points finally creating texture using roller printing, rollerprints creating rollerprints then points by roller printing or points roller printing, then rolling and

Richard's method for creating a hydraulic press involves welding together a more rigid steel frame than those available commercially. He advises scavenging scrap or junk steel pieces for this, then searching out some "U" channel (also called IL) or similar structural steel that's straight with thickness greater than 1/4 inch and can support drilling four holes into it's sides to drill four holes equal in height to your hydraulic jack or ram to cut threaded stock pieces that correspond with its height before bolting them all together with washers and nuts to complete this portable but solid resultant frame which supports weight up to 20 tons!

Part 1: Frame

Hydraulic presses are essential tools in any metalsmith's workshop. Utilizing hydraulic cylinders to exert compressive forces between an anvil and die, hydraulic presses create compressive forces which enable metalworkers to form finished pieces like pendants, earrings, rings, bracelet components and more from formed metal pieces.

There are various kinds of hydraulic presses on the market, but in general they all consist of a steel frame into which a hydraulic cylinder is installed. Cylinders are metal pipes equipped with two ports that enable input and output of hydraulic fluid through two ports located on opposite ends; pressure (or power) chambers are then separated from return chambers using piston rods to divide up each cylinder into distinct areas.

Typically speaking, higher pressure in the power chamber indicates greater hydraulic press power. However, it's important to keep in mind that a press can damage materials being formed; therefore, selecting one with appropriate levels of pressure for your type of work is crucial.

H-frame hydraulic presses are one of the top choices for jewelry makers, offering easy operation and high levels of pressure output. Furthermore, they feature a stationary bolster for manual alignment - though their press plates only accommodate small projects.

If you need something with more advanced capabilities, consider investing in a roll frame hydraulic press. With its similar simplicity to an H-frame press but much longer bolster that allows freer movement of press platens - roll frames allow you to accommodate larger pieces of metal while decreasing repositioning needs between die and material.

Part 2: Ram

Hydraulic presses use two cylinders that contain hydraulic fluid; the larger cylinder is known as the Ram while its counterpart, known as Plunger, holds hydraulic fluid under pressure to elevate Ram. When Plunger pushes downward, pressure builds in the fluid that lifts Ram, creating crushing force between these two pieces that crush any object between Ram and Plunger - this simple mechanical action offers greater versatility compared to more complex forms of presses.

Calculating a cylinder's force requires knowing its load capacity in pounds per square inch (psi). To do this, measure the diameter of its piston with a ruler; ensure this measurement corresponds with actual piston size rather than fittings on its end of cylinder; use a calculator to convert this measurement into an area and liquid pressure formula which accounts for both factors; this will yield your force number either in pounds or tons.

Hydraulic presses are invaluable tools for jewelry makers, helping to streamline processes such as cutting disks, forming metal sheets, drawing shapes and creating patterns quickly and efficiently. In this workshop, Richard will demonstrate how you can build an easy but efficient hydraulic press in your own studio.

Your press requires a sturdy steel frame, welded hydraulic ram and platen. In addition, rubber inserts that create depth when pressing can help achieve your desired depth; Richard will show you how to create these with old inner tubes. Finally, an underplate pipe welder will help secure everything together.

Part 3: Hydraulic Pump

A hydraulic press's central component is its hydraulic pump. It creates the pressure needed to drive both ram and anvil mechanisms with hydraulic fluid; usually two cylinders are used to do this job; these metal pipes feature ports for entering and extracting hydraulic fluid, with various diameters that determine their effectiveness as force generators.

Positive displacement hydraulic pumps are by far the most prevalent type of hydraulic pump available today, and are typically powered by a reciprocating hydraulic engine directly coupled to its piston or plunger. Power fluid is drawn from its reservoir through this piston into the mechanism while exhausted fluid travels back up again via another pipe back to the reservoir.

Hydraulic systems provide compact yet powerful energy where electrical, mechanical or pneumatic solutions would be too large or dangerous. Hydraulic pumps are essential components in these systems and must be chosen carefully according to each application - often by looking at power curves and calculating how much torque will be necessary at various flow rates.

Stamping is an extremely versatile technique that can be accomplished using various equipment and materials, including hydraulic presses. Stamping allows users to produce precise shapes using static pressure. Hydraulic presses are popularly used because they produce large volumes of work with relatively minimal pressure - they're also useful for performing many different operations such as cutting blanks or forming metal before piercing metal sheets.

Part 4: Hydraulic Hose

Hydraulic hoses provide vital connections for transmitting hydraulic fluid between components in a machine and their respective hydraulic reservoirs, making it one of the key elements in its function and operation. When one breaks or fails, it can be quite disappointing, and should therefore be chosen with care to meet equipment specifications - this means determining working and burst pressure as well as measuring using high precision tools like callipers. Also note that every hose has an approximate service life, and replacement should occur promptly when wear or tear are evident.

A hose can be constructed using various materials, including abrasion-resistant rubber and metal-braided synthetic rubber. Additionally, it can also be manufactured using helically or spirally reinforced tubes with carbon steel reinforcements, stainless steel reinforcements or combinations thereof, making them versatile enough to withstand various temperatures and pressure levels.

Richard shows how the hose can be used with pancake and impression dies, both designed to add interest to metal pieces by creating ridges in its surface. These ridges add visual interest and allow sculptors to produce unique pieces with unique designs. He also uses conforming dies for producing consistent shapes; these allow sculptors to achieve precise curves and angles when making symmetrical forms; plus plate that covers vise teeth to protect workpiece from damaging them! In addition, Richard shares numerous helpful tips, such as anneal metal before pressing, and how best utilize negative space created by dies to use its potential advantage!
