The difference between hydraulic press machine and punching machine
The hydraulic machine is a kind of special hydraulic oil as the working medium. The hydraulic pump is used as the power source. The hydraulic force enters the cylinder / piston to the hydraulic pipeline through the force of the pump. Then there are several sets of mutually compatible seals in the cylinder / piston. The seals in different positions are different, but they all play the role of sealing so that the hydraulic oil cannot leak. Finally, the hydraulic oil is circulated in the oil tank through the check valve to make the cylinder / piston work circularly to complete certain mechanical actions as a kind of machinery for productivity.
The design principle of the punching machine is to convert the circular motion into a linear motion. The main motor drives the flywheel and drives the gear, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to achieve the linear motion of the slider. The movement of the connecting rod is circular.
1. The difference between hydraulic press machine and punching machine
a. Punching machine is to press down quickly with inertial force, hydraulic press machine is to press down slowly with static pressure, and the hydraulic press machine can be selected with large extension;
b. The punching machine is rigid and cannot be adjusted. The hydraulic pressure is step less. The pressure can be increased and decreased at any time, which is easy to control. The extension refers to the degree of material deformation. In the case of large extension, the hydraulic press the punching machine may crack;
c. It is better to make handicrafts such as small badges. Or silver jewelry is better with ordinary punch. The extension press is small and the efficiency is high. Large extensions such as deep pots and cups. Punch is more suitable for blanking;
d. The punch press is a crank slider structure, which uses mechanical transmission. The hydraulic press uses hydraulic transmission;
e. The most typical difference between the two is different uses and different process equipment. Punching machines are mainly used for sheet blanking, and hydraulic press machine are mainly used for sheet forming.
2. The difference in application areas
Punching machines are widely used in stamping and forming of electronics, communications, computers, household appliances, furniture, transportation, hardware (automobiles, motorcycles, bicycles) and other hardware parts.
Hydraulic press machines are widely used in the spare parts processing of the automotive industry and the shaping, punching, correction and shoe making, handbags, rubber, molds, shafts, bushings parts of various industries, press molding, sheet metal parts The bending, embossing, sleeve drawing and other processes, washing machines, motors, automobile motors, air conditioning motors, micro motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery and other industries.
