Calculation method:
1. First make a rough calculation based on the rated gas pressure and standard cylinder bore.
For example: air pressure 0.5Mpa (5.0985811 kilogram force/square centimeter (kgf/cm2)), cylinder diameter 50mm (5cm), cylinder cross-sectional area =pi*(5/2 )^2=19.63(square centimeters)
So, the theoretical output under 0.5Mpa = 5.0985811*19.63=100.085 (kg force)
But it is only a theoretical contribution. The actual efficiency will be lower depending on the working conditions.
2. Rodless cavity cross-sectional area * working air pressure = piston thrust, rod-less cavity cross-sectional area * working air pressure = piston return force, common pneumatic components are designed normally The working pressure is 0.4 MPa, and the output pressure of the most common air compressor is 0.4-0.7 MPa. The reasoning required to push a 700kg workpiece needs to be tested, and the piston stroke must be determined as needed.
The five common installation methods of standard cylinders are: center swing type, free type, flange type, earring type and tripod type. Their fixing methods are as follows:
1. The mid-swing type installation method is to install the TC mid-swing in the middle of the cylinder to complete the installation and fixation of the cylinder. The cylinder with this installation method can swing around the middle trunnion, which is suitable for Yu long cylinder.
2. The free installation method refers to using the threads in the cylinder body to screw into the machine body for fixed installation without using installation accessories;or using the threads outside the cylinder body, Use nuts to fix the cylinder to the machine;you can also use screws to fix it to the machine through the screw holes in the end cover.
3. Flange type installation can be divided into front flange type and rear flange type. The front flange type uses flanges and screws to fix the cylinder at the front end cover. The flange type refers to installing a flange on the rear end cover and fixing it with screws. It is also suitable for situations where the direction of load movement is consistent with the axis of the piston rod.
4. The earring type installation method is divided into single-ear type and double-ear type. It refers to using screws to install the cylinder end cover and the earring type at the rear end cover of the SC series standard cylinder. The accessories are fixed together, and the cylinder has a pin hole in the vertical direction of the piston rod axis. The load and cylinder can swing around the pin. During rapid action, the larger the swing angle, the greater the lateral load the piston rod bears.
5. The tripod-type installation method, represented by LB, refers to using an L-shaped installation tripod to match the screw hole on the front end cover and use screws to install and fix the tripod. It can withstand large overturning moment and can be used in situations where the direction of load movement is consistent with the axis of the piston rod.
