What is hydraulics?
Hydraulic is used for the production, control. And supply of pressurized fluids. It is a technology. And applied science that encompasses the mechanical properties and uses of fluids. Hydraulic systems require a pump. And. like pneumatic systems, use valves to control the power and speed of actuators. Industrial hydraulic applications use 1,000 to 5,000 psi or more than 10,000 psi for special applications. The word hydraulic comes from the words hydor – water and aulos – pipes.

Hydraulic system
The hydraulic system requires the following equipment: hydraulic fluid, cylinders, pistons, pumps, and valves that control the flow direction, which is always in one direction. Unlike pneumatic systems, hydraulic systems are usually large and complex. The system requires more space because a container is needed to keep the fluid flowing through the system. Because the size of the system is larger, it requires more pressure; which is more expensive than pneumatic systems. Due to their generally larger oil size and incompressibility, hydraulic systems can lift and move larger materials. Hydraulic systems slower because oil is drained and requires more energy to move the piping. When configuring and planning. If a factory or plant has multiple hydraulic machines. It is best to have a central drive unit to reduce noise levels.
application
Due to the risk of possible hydraulic oil leakage from defective valves, seals, or hoses. Hydraulic applications cannot be applied to every container. Such as food and medical applications. They use in various everyday machine applications:
Elevators
Damn
Machine tools: hydraulic presses, hoppers, cylinders, and rams
Amusement parks
Turbines
Rising in a dump truck
Wheelchair lift
Digging arms for excavators
Hydraulic presses for forged metal parts
Airfoils on aircraft

Advantages of hydraulics
Hydraulic systems better to carry heavier loads and deliver higher forces due to fluid instability. Hydraulic systems perform multiple purposes. Simultaneously, including lubrication, cooling, and power transmission. Hydraulic motors operate at higher pressures, generating more power from smaller actuators. For efficient use of the hydraulic system. It important to select a component of a suitable size that corresponds to the flow rate.
Hydraulic systems
Hydraulic systems are larger and more complex systems. Fluids such as hydraulic oil more viscous. And require more energy to move. An oil storage tank also need from which the system will pump when the oil runs out. Initial costs are higher than with pneumatic systems because they require the power. That needs to added to the machine. Any leakage in the hydraulic system can cause serious problems.

Pneumatic systems
These preferred over hydraulic systems for their low cost, flexibility, and higher level of system safety. Pneumatic systems are best suited for contamination-free applications because they provide a clean environment for industries such as biotechnology, dentists, pharmaceuticals, and food cell suppliers. Because they use clean, dry, compressed air, the system can easily carry things. The straight and simple design prevents clogging and reduces maintenance requirements. They are reliable and have relatively low initial setup costs because they operate with relatively low pressure and inexpensive components that reduce operating costs.
No container
No container is needed to store the compressed air. As it extracts from the surrounding atmosphere and filter. The whole system is therefore designed using standard cylinders and other components. The air or gas used in the pneumatic system is normally dry and moisture-free, so it does not cause any problems with internal components. Pneumatic systems allow the cylinders to move quickly thanks to the air compressor’s flow rate. The air very flexible and can pass through the tubes very quickly and with little resistance.
Information on press brakes
Common Bantam Press Brake
Pressure brakes are metal forming machines that are used to bend and fold sheets and sheets by pressing them between tools called punches and dies. Wrinkles and lips help harden metal panels. To complete the bending operation. It is necessary to bend the material slightly forward. From the desired shape so that the material repeatedly overcome due to the remaining tensile and compressive stress.
Types
The most important classification of the brake system is the way in which this force acts – hydraulic, mechanical, servo and pneumatic.
Hydraulic press brake
The hydraulic press brake has become the most common press brake used since the 1970s. It is designed for both special sheet metal processing and continuous industrial production processes from single-cycle operation to automatic cell components. Driven by two synchronized hydraulic cylinders, hydraulic press brakes are safer and cheaper than mechanical press brakes. And offer benefits such as variable speed control, fast recovery, and the ability to reverse the stroke at any time.
Mechanical brake system
The mechanical brake system uses an electric motor to control the flywheel, which stores kinetic energy and releases it through one of several transmission configurations. Mechanical presses precisely high-speed machines with low maintenance costs.
CNC press brakes
Press brakes also called CNC press brakes. Provide convincing performance through two synchronized motors used to drive the belt and pulley mechanism. The motor replaces the flywheel and clutch with mechanical press brakes. Servo-driven presses highly flexible machines due to their ability to precisely control the stroke. And speed of the ram using servomotors. Mechanical brake presses are an even better choice for high volume applications. While presses better for special low-volume applications than custom applications.
Pneumatic press brakes
Pneumatic press brakes provide a convincing effect from a source of compressed air. Applications for pneumatic presses include bending, grinding, punching, forming, drawing, extrusion and assembly. Pneumatic presses may not provide the same performance as hydraulic press brakes. But they provide fast and clean operation. Pressure brakes can run in many different shapes depending on the equipment used, including:
Technological possibilities of bending presses
The use of bending technology based on knowing the nature of bending machines. And their technological possibilities. The possibility of using a given machine tool for the production of products largely depends on the technological possibilities of the machine tool.
Important parameters
The most important parameters are the bending force of the machine, the distance between the upper and lower beams in the open position, and the working range. Productivity affect by operating speed and upward speed. From the point of view of the production of the product, the maximum width of the sheet that can fit on the bench, and the number of controlled coordinates. And their nature also important. The design of arc presses and starting coordinates discuss in more detail in the following chapters.
Bending presses
There are many manufacturers of bending presses. The key selection criteria are technological possibilities, reliability, ease of use, maintenance conditions and. Of course, price. Many equipment-related manufacturing companies appear in many countries. And elsewhere. There is plenty of materials on the manufacturers’ websites. To introduce machine tools, product catalogs. And more detail product descriptions can also find on the Internet. Undoubtedly. These three important criteria for product selection. Bending press. Which will important for the company.
