The difference between a hydraulic press and an ordinary punch press
The essential difference:
The design principle of the punch press is to convert circular motion into linear motion, and the main motor outputs the power. It drives the flywheel and drives the gear, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to achieve linear motion of the slider. The motion from the main motor to the connecting rod is circular motion.
Hydraulic press (a type of hydraulic press) uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder/piston through the hydraulic pipeline through the force of the pump. Then there are several sets of seals in the cylinder/piston that cooperate with each other. The seals at different positions are different, but they all play a sealing role so that the hydraulic oil cannot leak. Finally, the hydraulic oil is circulated in the tank through the one-way valve to make the cylinder/piston circulate and perform work to complete certain mechanical actions and serve as a kind of productivity machinery.
Differences in application fields
Punch press: widely used in stamping of electronics, communications, computers, household appliances, furniture, transportation, (cars, motorcycles, bicycles) hardware parts, etc. and molding.
Hydraulic press: widely used in the processing of spare parts in the automotive industry and the shaping, edge punching, correction and pressing of shoemaking, handbags, rubber, molds, shafts, and bushings of various products in various industries. Assembling, embossing molding, bending, embossing, sleeve stretching and other processes of plate parts, washing machines, electric motors, automobile motors, air conditioning motors, micro motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery and other industries .
