QGB cylinder series heavy duty working principle, types and functions

A. QGB series of heavy cylinder works: according to the size of the work force needed to determine the thrust and tension on the piston rod. In order to select the output force should make the cylinder when the cylinder is slightly allowance. If picked the small cylinder diameter, the output power is not enough, the cylinder does not work; But the diameter is too large, the device not only heavy, high cost and the gas consumption increases at the same time, cause energy waste. In fixture design, should as far as possible the power mechanism, in order to reduce the size of the cylinder. Second, QGB heavy cylinder type: pneumatic transmission of compressed gas pressure can be converted into mechanical energy of the pneumatic actuators. Do reciprocating linear motion of the cylinder and do reciprocating swing, See the figure) 。 Do the reciprocating linear motion can be divided into the single-acting cylinder, double acting, diaphragm type and the impact of cylinder. (1) the single-acting cylinder: only one end of the piston rod, air supply from one side of the piston can produce pressure and air pressure forces the pistons to generate thrust, by spring or self-respect to return. (2) : double-acting cylinder from the pistons alternately on both sides of the gas supply, power output in one or two direction. (3) the diaphragm cylinder: replace with diaphragm piston, output force in only one direction, with a spring return. It sealed performance is good, but short. (4) the impact cylinder: this is a new type of component. It put the compressed gas pressure can be converted to the piston velocity ( ~ m/s) The kinetic energy of moving to do work. Increases the impact cylinder cover with nozzle and discharge port. The cover and the cylinder piston into gas storage chamber, tail and head cavity 3 rooms. It is widely used for blanking, punching, crushing and shaping and other assignments. Do reciprocating swing oscillating cylinder cylinder said, the blade will be divided into two, its inner cavity to two cavity alternating gas supply, output shaft do swing motion, oscillating Angle is less than °. In addition, there is the rotary cylinder, gas-liquid damping cylinder, and the step cylinder, etc. Three, heavy cylinder effect: the compressed air pressure can be converted into mechanical energy, driving mechanism as a straight line reciprocating movement, swinging and rotary motion. Four, the classification of the heavy cylinder: the straight line reciprocating movement, swinging movement of the oscillating cylinder, gas cylinder of claw, etc.
