Short Answer:
A hydraulic press is a means of generating mechanical advantage by using a fluid and two different sized pistons. Hydraulic presses can be used for a lot of things. In a shop it is often used to press metal pins into holes or bearings into housings so that metal parts can be made to stay together without fasteners or threads. In a lab hydraulic presses are often used to compress powders into solid cylinders or tablets. Sticks of chalk used on blackboards are made this way as well as aspirin tablets and other common products. Hydraulic presses can be run manually using the power of someone's arm or they can use an electric pump to create the necessary pressure in the hydraulic fluid.
How it works:
If I have a piston that is three inches in diameter sitting in a cylinder and I pump fluid in the bottom of it that piston will rise and lift whatever is above it such as a 2000 pound car. The pressure of the 2000 pound car on a three inch diameter piston produces about 261 pounds per square inch of pressure in the fluid below the piston.
Piston Area = Pi*r^2 = 3.14 * 1.5 * 1.5 = 7.65 square inches
Pressure = Force / Area = 2000 pounds / 7.65 square inches = 261 pounds per square inch
If I have a pump with a piston that is only 0.25 inches in diameter (area = 3.14 * 0.125^2 = 0.049 square inches) I only need to push on it with about 98 lbs to lift a 2000 lb car.
This works out to about a 20:1 mechanical advantage. The downside is that for every inch I want to raise the car I have to push the small piston in about 20 inches. This is how a hydraulic jack or "bottle jack" you'd find in a garage works.
A practical jack or hydraulic press would have three valves and a fluid reservoir in addition to the pump and lifting piston. The pump would push fluid through a check valve, which only allows fluid to through one way, into the lifting piston cylinder causing it to rise when the handle is pressed down. When the handle is lifted the pump would suck fluid from the reservoir through another check valve. This lets you move the pump back and forth to get 20 inches or more of motion without having a 20 inch long pump piston. The third valve would let the pressurized fluid back into the reservoir when you wanted to lower the car. The reservoir would not be pressurized.
Hydraulic press for bending sheet metal or metal cutting excessive force is used. A hydraulic press hydraulic fluid pressure in the cylinder caused by excessive force. These presses have many applications in industry and manufacturing.
A hydraulic shop press is used to generate compression energy. It uses the Brahma press. This is created after the toilet. This was used with immense water pressure.
It can not. Generally use press brake to bend sheet metal. Press brake has 3 kinds of series. Manual press brake by foot, mechnical press brake, hydraulic press brake.
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.
Hydraulic actuators. Also called hydraulic rams or hydraulic cylinders.

The ___________ press performs the same function as a hydraulic press, but at lower pressures.
A hydraulic baling press machine is compressing equipment powered by a hydraulic system. A hydraulic baling machine is typically made up of three key components: the machine body frame, the electric system, and the hydraulic system.

The idea behind the hydraulic press (machine or bench press) is that a liquid, when displaced, will exert pressure or force equally across the surface it is forced against. Because of this, hydraulic presses are commonly used for automotive and industrial repair shops, where pressing, bending, straightening, and forming is required.
When talking about hydraulic press machines, daylight means that there is a gap between the top and the bottom of the press when the top and bottom come together. This should not happen to ensure that proper pressure is achieved.
You need a hydraulic press to press the pin into the piston and through the connecting rod
You can find high quality hydraulic presses at Harbor Freight and also at Northern tool. I would suggest visiting their websites and choosing a press that fits your specific business needs.
