What Is a Hydraulic Press Used For in the Construction Industry?

Hydraulic presses are machines that utilize liquid as the working medium to transfer energy, using Pascal's principle as its foundation.

Hydraulic presses are essential tools in many industrial processes, such as stamping, forming, forging and crushing. Not only that but they can create components for machinery as well as parts for commercial and industrial products.

Stamping

Stamping presses are metalworking machine tools that can shape or cut metal. These presses come in various sizes for both sheet and coil forms of material.

Hydraulic presses utilize a hydraulic cylinder to generate compressive force that is then applied to metal through dies. They are commonly used for blanking, clinching, deep drawing, forging, molding and punching tasks.

Mechanical presses are capable of producing fast and dependable results from coils of sheet metal. They offer speedy production rates for simple, shallow-formed parts made from coils. With their repeatable nature, you can count on these presses to deliver consistent outcomes over multiple cycles.

When selecting a stamping press, factor in frame construction--rigidity, bolster thickness and dimensional capacity--as well as horsepower.

Stretch forming

Hydraulic presses can be employed for stretching forming to produce precision metal parts. They're commonly employed in aerospace industry applications for wing stringers and chords made of aluminum alloy.

Stretch forming is a process that involves clamping long pieces of metal (blanks) between jaws attached to moving arms. The blanks are then wrapped around an internal die for shaping.

Stretch forming machines come with several options, such as computer numeric control (CNC) and integrated front panels. With CNC, the operator can program each jaw assembly's radius without having to manually adjust each individual locking screw.

Stretch forming is a process that involves placing long sheets of metal (blanks) between circular gripping jaws attached to an adjustable arm. The arm then rotates on large machined pins with bearings.

Deep drawing

Deep drawing is the process of shaping flat sheet metal into a three-dimensional form. This technique often results in hollow shapes such as cups and bowls, but can also be employed for precision parts with intricate contours.

Forming is typically done in a press, using punch and dies to create the desired profile. This step can be carried out using either hydraulic or mechanical presses.

When deep drawing, a blank must be precisely shaped for optimal metal flow and minimal forces that could cause tearing. To do this, various parameters need to be taken into consideration such as corner radius and how much material can be added to form a flange.

Savage offers several types of presses suitable for this forming process, such as four-post guided platen, gib-guided and straight side housing type frames. All these presses can be fitted with hydraulic powered cushions, knockouts and ejectors.

Metal forming

Hydraulic presses for metal forming offer the versatility to shape or mold materials such as steel, aluminum, brass and copper with precision. Models range from small table top presses up to massive units that can apply hundreds of tons of pressure.

Before selecting a forming process, the material and strength must be taken into account. Metal forming is an efficient, economical and versatile option for producing components that meet specific specifications.

Forming metals follows the material sciences principle of plastic deformation, in which force is applied to a raw material that permanently changes its physical shape and cannot be undone.

Roll forming and stamping are two forming processes used to manufacture metal parts. Both involve feeding a sheet metal between two or more rollers in order to achieve the desired cross-section.
