The working principle of the mechanical press?
The design principle of the mechanical press is to convert circular motion into linear motion.
The flywheel is driven by the main motor and the clutch drives the gear, crankshaft (or eccentric gear) and connecting rod to reach the linear motion of the slider.
The motion from the main motor to the connecting rod is circular.
The working principle of hydraulic presses
The hydraulic oil press (a kind of hydraulic press machine) is a kind of machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source, by the force of the pump the hydraulic oil enters the cylinder/piston through the hydraulic pipeline, and then there are several sets of mutually matching seals in the cylinder/piston.
The seals are all different in different locations, but they all act as a seal so that the hydraulic fluid cannot leak.
Finally, the hydraulic oil circulates through the tank through a check valve, causing the cylinders/pistons to work in cycles, thus completing a certain mechanical action as productivity.
Let’s move on to the differences between the mechanical press and hydraulic press.
Mechanical Press vs. Hydraulic Press
1) Punch press is inertia force, rapid downward pressure; hydraulic press (hydraulic press) is static pressure, can be slow downward pressure.
If the elongation is large, the hydraulic press can be selected.
2) Punch presses are rigid and cannot be speed controlled; hydraulic presses are stepless speed controlled and the pressure can be changed to larger or smaller at any time, which is easy to control.
The amount of elongation refers to the degree of deformation of the material.
Possible cracking may occur during hydraulic press punching in the case of large elongations.
3) It is better to use an ordinary mechanical press for small emblems or silver jewelry because of its low elongation pressure and high efficiency.
The product with large elongation including deeper pots and cups.
Punching machines are more suitable for blanking.
4) Punch presses are crank-slide structures that utilize mechanical transmission; hydraulic presses utilize hydraulic transmission.
5) The most typical difference between the mechanical press and hydraulic press is that they are used for different purposes and are different types of process equipment.
Differences in application areas
Punching machines are widely used in stamping and forming hardware parts for electronics, communications, computers, household appliances, furniture, transportation, (automobiles, motorcycles, bicycles) and so on.
Hydraulic presses are widely used in auto parts processing and various industries for shaping, punching, calibrating, shoemaking, handbag, rubber, mold, shaft and bushing parts pressing, embossing, sheet metal parts bending, embossing, sheath stretching, washing machines, electric motors, automotive motors, air conditioning motors, micro motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery.
These are the differences between a hydraulic press and a mechanical press.
Both machines have their own advantages.
I believe that with the development of technology, the future of automation equipment will be more and more intelligent.
