Stamping and oil pressure are the same concept, but the oral name is different. Stamping generally refers to the impact on some hardware parts during processing. Such as trimming, punching, stretching, etc. There are two kinds of stamping equipment: mechanical punch and hydraulic punch. The invention has the advantages of high stamping speed, large impact, high noise and high price. Hydraulic press is cheap, silent and shock-free, and can be put on the floor to work. Hydraulic press has incomparable advantages over punch press.

The principle of punching machine is that the motor drives the big flywheel, and the clutch and transmission gear drive the crank-connecting rod mechanism, so that the moving slider moves up and down, thus driving the die to produce a huge impact on the steel plate and pressing it instantly. The hydraulic press is that the oil pump delivers the hydraulic oil to the integrated valve block through the hydraulic circuit, and distributes the hydraulic oil to the upper cavity or the lower cavity of the oil cylinder through various check valves and overflow valves. Using Pascal's principle, the oil cylinder generates high pressure, and the oil cylinder moves under the action of high pressure oil.

Four-column fast hydraulic press is widely used. You can go to the official website of a hydraulic press manufacturer in www.dgyouya.com for more information. Hydraulic press is widely used in all walks of life. Compressive and tensile force testing system. Stamping, forming, shallow drawing, shaping and press-fitting of metal or non-metal parts, pressing of glasses, locks and hardware parts, press-fitting of electronic connectors, electrical parts, motor rotors and stators, etc. Can understand the working principle of punch and hydraulic press. Now most of the punching machines have been replaced by oil presses.
