Classification of impact cylinders, animation of impact cylinder principles and working process

Working process of impact cylinder

(1) First stage, reset section: The air source is supplied from hole A, exhaust from hole B, the piston rises and seals the nozzle with a sealing gasket, CylinderThe upper chamber becomes a sealed air storage chamber.

(2) The second stage, energy storage section: the air source is changed to exhaust from hole A and air intake from hole B. Since the upper chamber air pressure acts on a smaller area on the nozzle, while the lower chamber has a larger acting area, the upper chamber can store a high amount of energy.

(3) The third stage, impact stage: the pressure in the upper chamber increases and the pressure in the lower chamber continues to decrease. When the pressure ratio between the upper and lower chambers is greater than the area ratio between the piston and the nozzle, the piston leaves the nozzle. ,The gas in the upper chamber is quickly filled into the space between the piston and the middle cover. The piston will move downward with great acceleration, and the pressure energy of the gas is converted into the kinetic energy of the piston. This energy is used to impact the workpiece and produce a large amount of energy. impact.

Classification of impact cylinders

Market owners mainly classify impact cylinders into two categories: QGT type and CMT type.

QGT impact cylinder

It converts the pressure energy of compressed gas into the kinetic energy of high-speed (10~20 meters/second) movement of the piston to perform work. This impact cylinder adds a middle cover with a spout and a drain port. The middle cover and piston divide the cylinder into three chambers: air storage chamber, head chamber and tail chamber. It is widely used in various operations such as blanking, punching, crushing and forming.

CMT type impact cylinder

This is a new type of impact cylinder that greatly provides impact force by weighting the piston rod and reducing the friction coefficient. This series of impact cylinders have compact structure and huge impact force. For example, this series of impact cylinders with a cylinder diameter of 38mm and a stroke of 60mm can have a maximum impact force of 3 tons. The impact force is that of an ordinary impact cylinder with the same stroke and cylinder diameterCylinder more than 10 times. Due to the use of impact buffer devices, this series of impact cylinders can not only provide greater impact force, but also ensure their service life. This impact cylinder is particularly suitable for production line inspection position marking, punching and other operations. Due to its very small length, it is suitable for installation in relatively compact spaces. The requirements for the size and distance of the installation location are relatively low.
