Differences Between Punch Press And Hydraulic Press MachineUpdate：2021-08-24 Hits：185
Some times we get enquiry about hydraulic press, but punch press is suitable for customers after we communicate with them.The reason is that they don't know the difference between punch press and hydraulic press machine. If you want to know the difference and characteristics of punching press and hydraulic press machine, you must first understand the definition of the two:Punc Press: Punching press is also called punching machine, the punch press uses its transmission structure to produce appropriate pressure and kinetic energy near the bottom dead center along with the die resulting in plastic deformation of the workpiece according to the desired shape. Which is mainly used for processing sheet metal parts.
There are still many differences between the two, as following:
In principle: the punching machine drives the flywheel through the electric motor, and drives the crank and connecting rod mechanism through the clutch and the transmission gear to move the slider up and down, and drives the drawing die to form the steel plate. The hydraulic machine is an oil pump that delivers hydraulic oil to an integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and overflow valves, and moves the cylinder under the action of high-pressure oil.
Application: hydraulic press is suitable for various processes such as bending, forming and flanging of central load parts. After being equipped with a punching buffer device, it can also be used for punching and blanking processing. It is used in the shipbuilding industry, pressure vessel industry, chemical industry, etc. The industry's first choice. The punching machine is mainly used for the processing of sheet metal parts.
Classification
Stamping machine classification:
According to the driving force of the slider, it is divided into mechanical punches and hydraulic punches
According to the slider movement mode, it can be divided into single action, double action, and multiple action
According to the sliding block drive structure, there are crankshaft punches, crankshaft-free punches, toggle punches, friction punches, spiral punches, rack punches, connecting rod punches, and cam punches.
Hydraulic press classification
Hydraulic presses can be divided into hot forging hydraulic press machine, four column hydraulic press machine, c frame hydraulic press machine, cold forging hydraulic press, and double action hydraulic press machine.
