Double Action Hydraulic Press: A Complete Guide

What is a Double Action Hydraulic Press?

A hydraulic press machine that is used to convert metals into various shapes and forms, through force is known as a double action hydraulic press. The press applies pressure to the workpiece’s upper and lower surfaces at the same time. These presses consist of two presses, both acting in opposite directions. These presses are used in many industries. Metal shaping and deep drawing are only two of the many tasks they are capable of.  

Types of Double Action Hydraulic Presses

Double action hydraulic presses have found significant importance in many industrial applications. These are divided into different types according to the applications. Some of the double action hydraulic presses are discussed below:

· Deep Drawing Presses

These presses are used to shape metals into different shapes using deep drawing technique. It has an outer slide and an inner slide, which controls the holder blank and performs drawing operations, respectively.  This dual action mechanism helps the material to flow uniformly across the press.

· Forging Presses

This type of Double Action Hydraulic Press make different shapes from metal pieces by applying compression force. The force is applied by press in two directions to control the deformation which increases the strength of the formed shape. The pressure that this force generates is evenly distributed. As a result, the mechanical properties are improved and the grain structures become fine.

· Extrusion Presses

In extrusion presses dies are used to hold the material that is to be shaped. Dies have the shape that is required to be formed. When the material is pressed it takes the shape of the die. In this type of double action hydraulic press the force is applied on both sides of the die to achieve high dimensional accuracy.

· Stamping Presses

Double-action stepping press have two slides that are used the inner and outer slide. The inner slide is used for stamping and the outer slide is used to manage the blank holder. The stamping operations are blanking, punching, and embossing on metal sheets. The dual action mechanism of this press helps in accurate positioning of the material during the operation. This increases the dimensional accuracy of stamped parts.

· Hydroforming Presses

Hydroforming press use fluid to apply pressure on the metal parts to shape it. The pressure produced by the fluid is applied in both upward and downward directions on the workpiece.

· Powder Compacting Presses

It is a type of double action hydraulic press in which the material in powder form is compressed to produce different shapes. In order to maintain a consistent density and lessen the likelihood of flaws, the material is subjected to compressive force in both directions.

Advantages of Using Double Action Hydraulic Presses

Double action hydraulic presses have many advantages, which makes them suitable for many industrial applications. Some of these advantages are:

· High Control and Precision

In double action hydraulic press, the force is always applied in two opposite directions. These presses have greater control over the force and pressure applied on the metal sheets. The control allows the press to improve the quality of complex forming operations.

· Flexibility in Operations

The dual action mechanism of double action hydraulic press can perform complex forming operations that single action mechanism presses cannot.

· Improved Efficiency and Productivity

In double-action hydraulic press, the dual-action mechanism reduces the need for multiple machines. It helps in improving the production efficiency. These presses have low cycle time which effects the throughput time.

· Uniform Pressure Distribution

Double action hydraulic presses distribute the force uniformly across the workpiece. As a result, the press can achieve high dimensional accuracy. The risk of defects is also reduced. These presses form metal shapes with high-quality standards.

· Energy Efficiency

Double-action hydraulic presses have low energy consumption. The force can be controlled in these presses which prevents unnecessary force application on the workpiece. These presses consume less energy. It also lowers the operational costs and environmental footprints.

· Less Operator Fatigue

Double action hydraulic presses are automated. This reduces the workload of operators. The design features of the press make sure that the operators are safe. It helps in increasing the productivity and makes the work environment safe. 

Applications of Double-Action Hydraulic Presses in the Industry

Double action hydraulic presses have found their application in different industries. The dual action mechanism of these presses lends themselves to difficult forming operations.

· Automotive Industry

Body panels, chassis parts and engine components are made using these presses. The body panels, chassis parts and engine components are made by double action hydraulic presses. Good quality components can be produced using these presses which can perform deep drawing and stamping operation. Double action hydraulic press is very accurate in operations and meets standards of quality, safety and performance standard. The automation of these presses decreases operations cost and increases productivity.

· Aerospace Industry

In aerospace industries, components with high strength-to-weight ratios are required. Double action hydraulic presses can make complex and lightweight components from aluminum and titanium. This is the reason for their use in making fuselage sections, wing components, and engine casings for aircrafts.

· Metal Fabrication

Double action hydraulic presses are used for metalworking like bending, punching, and forming. Copper, steel, and aluminum are some of the metals these presses are capable to handle. These presses can perform customized work on the metals to produce complex shapes.

· Consumer Goods Manufacturing

Double action hydraulic presses are used to make daily use items such as kitchen appliances, electronics enclosures, and decoration pieces. These presses are flexible and controllable, which allows them to customize the product manufacturing.

· Electrical and Electronics Industry

Electronics industries manufacture connectors, housings and heat sinks by using this press.  The force applied by these presses is controlled, which makes them suitable to make electronic components without damages and defects.

FAQs

What are the differences between a double action hydraulic press and a single action press?

A double action hydraulic press applies force in two directions, upwards and downward. A single action press can exert a force in only one single direction.

What are the key parts in a double action hydraulic press?

A double action hydraulic press have 5 main components. A hydraulic cylinder performs dual action force application, a ram that applies pressure, a die that shapes the material, and a blank holder that restricts the movement during operation.

How does the hydraulic system in a double action press work?

The hydraulic system has fluid which generates pressure to apply force. The hydraulic pump provide fluid to the cylinders which creates pressure. The generated pressure moves the ram and blank holder in opposite directions.
