A punch press is a stamping press. The design principle of a punch press is to convert circular motion into linear motion, which is driven by the main motor to drive the flywheel. The clutch drives the gears, crankshaft (or eccentric gear), connecting rod, etc. to achieve linear motion of the slider. The motion from the main motor to the connecting rod is circular motion.

The guide rails of punching machines are divided into sliding guide rails and static pressure guide rails. The copper slide plates of punching machines have the advantages of simple structure, convenient manufacturing, good stiffness, and high vibration resistance. The static pressure guide rails of punching machines can be divided into hydraulic pressure guide rails and gas pressure guide rails.

There is an oil chamber between the two working surfaces of the hydrostatic guide rail of the hydraulic press. After lubricating oil with a certain pressure is introduced, a hydrostatic oil film can be formed, making the working surface of the guide rail under pure hydraulic friction, without wear, and with good accuracy retention; At the same time, the friction coefficient is also extremely low, greatly reducing the driving power; Low speed non crawling, high load-bearing capacity, and good stiffness; In addition, the oil has a vibration absorption effect and good vibration resistance. Its disadvantages are complex structure, requiring a fuel supply system, high oil cleanliness requirements, and the increasingly widespread application of static pressure guide rails in punching machines.

The copper skateboard adopts a high-quality raw material casting structure, which has extremely high shock absorption effect. After tempering to eliminate internal stress treatment. Adopting hexagonal rectangular guide rails, all of which are made of alloy copper, with high wear resistance, good stability, and high accuracy. Mold height adjustment device: Closed type electric height adjustment, with a display accuracy of 0.1mm for the slider mold height. Built in transmission turbine ensures smoothness and accuracy when adjusting the mold height. The hydraulic overload protection device is used inside the slider: when the gas-liquid type exceeds the rated tonnage by about 10%, an overload reaction occurs, and the slider automatically stops to ensure that the main components such as the body are not damaged in any way. Using a pneumatic balance cylinder to balance the weight of the slider and upper mold has strong stability and good accuracy retention.
