The pressyes They are machines or tools whose main function is to change the form of a work piece by exerting pressure on it. These presses are used in different manufacturing processes such as stamping, forging or stamping materials.
In addition, it is necessary to know that there are different guys and industrial press subtypes according to their functions: hydraulic, mechanical and pneumatic.
1. Mechanical presses
The mechanical presses They are mainly used to deform parts such as bronze, iron or steel to high pressures. It is often used in fields such as the manufacture of parts for automobiles or aircraft, or hardware materials.
This type of press has a electric motor that rotates a "flywheel" that acts as an energy accumulator. The electric motor suddenly releases that stored energy and applies force in several tons about the piece.
In turn, within this type of presses we can find other subtypes that vary depending on the mechanical components used to exert force:
- press crank: uses a connecting rod that is placed through a crankshaft.
- press screw: uses the rotational energy of a motor to turn a large screw, and is very useful in carpentry or DIY workshops.
- Press eccentric: uses a motor to drive an eccentric shaft. It is recommended for cutting, punching and stamping jobs.
- press Rack and pinion: this type of press drives the electric motor through a gear directly connected to the drive shaft
- press knuckle joint: It is capable of transmitting great force, because it converts the power of the engine through a powerful connecting rod.
2. hydraulic presses
In the case of hydraulic presses, these use the pressure of two cylinders of different diameters, which are filled with Water either oil and, which allow the piston to move up and down.
Hydraulic presses have ability up to 15,000 tons, and are used for press work or for lifting heavy objects. Although they are especially used to stretch, extrude, perforate and stamp metals of large mm thickness.
In the same way as the mechanical press, the hydraulic press has, in turn, other subtypes What:
- Hydraulic press universal
- hydraulic press a column
- hydraulic press four columns
- Hydraulic press horizontal
- Hydraulic press vertical
In addition, this type of press that has advantages over mechanical presses due to:
- Your purchase cost is lower.
- Very little bit maintenance expense, because it rarely breaks down and it is almost always minor problems.
- Count with one elderly control and flexibility, since it can control depth distances or work times by means of timers and feeders.
- Elderly security for the worker.
3. Pneumatic presses
The pneumatic presses they use a mechanism similar to hydraulic presses, the only difference is that, instead of compressing a fluid, this press compresses air to increase the pressure inside the cylinder.
Also, pneumatic presses are much more fast, and they are capable of stopping in the middle of the process when an operator opens the valves to release air, they are easy to use, and they do not need liquids to work.
Specifically, this type of press is used to numerous processes such as the inflation of rubber and derivatives or to stamp materials such as cardboard, plastic and many others. They are usually the most used in workshop tasks.
