How to Manufacture Hydraulic Press Tooling

No matter if you're in the aerospace parts, appliance components or food and beverage cans industry, hydraulic press tooling plays a pivotal role.

Hydraulic presses employ a system of cylinders and rams to generate mechanical pressure necessary for shaping or deforming materials. They can be operated manually, pneumatically, or electrically depending on the application.

Hydraulic system

Hydraulic presses are widely used in fabrication, assembly and maintenance processes. They rely on hydraulic pressure from a pump to push steel cylinders into materials with precise force.

Presses work off Pascal's law, which states that pressure equals force divided by area. This enables fluid power systems to generate full tonnage throughout each stroke.

A hydraulic press can be tailored to fit any production or assembly operation by altering its functionality. This includes altering the die, pressure, stroke speed, or process position.

Hydraulic presses are an efficient means of producing high-quality components with minimal space requirements. This results in the efficient use of assets and increased productivity.

Cylinders

Hydraulic presses are indispensable tools in many industries, helping fabrication, assembly and maintenance facilities fit, bend and assemble sheet metal parts and bearings. Additionally, hydraulic presses can be employed for other forming operations like forging, clinching, molding and stamping.

When a hydraulic press is in operation, liquid under pressure pushes a steel cylinder into material at an established force. This expeditious process helps metal smiths and other artisans produce more items in less time.

These cylinders come in various configurations and each requires specific tolerances when it comes to shape, size and position. Furthermore, they must be able to withstand a significant amount of pressure, so the right design and manufacturing technique is key.

Rams

The hydraulic press' ram is an essential element, extending and retracting to apply pressure on a workpiece. This force can be utilized for various tasks like blanking, metal forming and welding, bending, drawing and piercing.

The ram is a hollow cylindrical tube filled with fluid. When activated, this fluid interacts with the plunger and propels the ram into your workpiece.

Hydraulic rams are used to support heavy loads, spread and pull apart parts, tighten and loosen fasteners, lift equipment and move machinery, etc.

Hydraulic rams can be designed in a variety of ways, depending on the requirements for the application. Options include standard, adjustable and programmable models.

Plungers

Plungers are an integral component of hydraulic press tooling and can be produced through various methods. CNC machining or manual labor on a lathe are the two primary ways to manufacture plungers for hydraulic presses.

Before one can successfully manufacture plungers for a hydraulic press, one must first understand its operation and how to set it up correctly. To accomplish this task, reading an extensive hydraulic press instruction manual is your best bet.

The plungers in a hydraulic press are used to generate pressure and push or pull items. They also enable metal extrusion. Usually made of steel, these plungers have been designed specifically for fitment into the press.

Platens

Platens are large, heavy flat steel plates used in hydraulic presses. These devices compress and compact materials to form new products or reduce scraps in size.

Platens for hydraulic press tooling can be produced through either a manual or automated process. Manual presses feature an operator-operated cylinder that moves up and down with the platen stacked atop.

These hydraulic presses come with a range of tonnage capacities and can be used for different manufacturing processes like rubber molding, bonding and laminating. For temperature control and accuracy, these hydraulic presses may have electrically heated or steam heated platens installed.

In addition to heating capabilities, presses also come equipped with other features designed to optimize production. Programmable limit switches enable operators to limit the retract distance of the ram in order to shorten cycle times and prevent over-extension of parts.
