Hydraulic press: hydraulic press is a kind of machine which uses liquid as working medium to transfer pressure to realize various processes.
Stamping machine: also known as punch press, mainly used for sheet metal parts processing.
There are many differences between them, as follows
The hydraulic press is an oil pump to transport the hydraulic oil to the integrated cartridge valve block. The hydraulic oil is distributed to the upper chamber or lower chamber of the oil cylinder through each one-way valve and overflow valve. Under the action of high-pressure oil, the oil cylinder moves.
The press drives the flywheel by motor, and drives the crank connecting rod Zhidao mechanism through the clutch and transmission gear to make the sliding block move up and down, and drives the drawing die to form the steel plate.
The hydraulic press is suitable for bending, forming, flanging and other processes of center loaded parts. Equipped with blanking buffer device, it can also be used for punching and blanking. It is the first choice for shipbuilding industry, pressure vessel industry and chemical industry. Stamping machine is mainly used for sheet metal parts processing.
Classification of hydraulic press
Hydraulic press can be divided into hot forging hydraulic press, four column hydraulic press, single arm hydraulic press, gantry hydraulic press and double column hydraulic press
According to the slider driving force, it is divided into mechanical punch and hydraulic punch
According to the motion mode of the slider, it can be divided into single action, multiple action and multiple action
According to the slider driving structure, it can be divided into crankshaft type punch, non crankshaft punch, elbow joint punch, friction punch, screw punch, tooth answer bar punch, connecting rod punch and cam punch
