Introduction of swing cylinder of press parts

The press swing cylinder is a kind of cylinder in which the output shaft is limited to a certain angle for reciprocating swing, also known as a rotary cylinder. It is the pressure that will compress the air. It can be converted into mechanical energy, output torque, and make the mechanism realize reciprocating swing.

The maximum swing angle of the commonly used press swing cylinder is divided into three specifications: 90°, 180°, and 270°. According to the structural characteristics of the swing cylinder, the swing cylinder can be divided into two types: rack and pinion type and vane type.

①Press rack and pinion swing cylinder

Rack and pinion swing cylinders are available in rack and double rack. Because the 10-28 is a single rack type swing cylinder, its structural principle is that the compressed air pushes the piston 6, thereby driving the flute assembly 3 to move in a straight line. The window strip 3 pushes the street wheel 4 to rotate, and outputs torque from the output shaft 5 (gear shaft). The output shaft is connected with the rotating shaft of the external mechanism to make the external mechanism swing.

②Press blade type swing cylinder

The vane-type swing cylinder of the press can be divided into three types: single-blade type, double-blade type and multi-blade type. The more blades, the smaller the swing angle and the larger the group moment. The single-blade output swing angle is less than 360°. The double-blade output swing angle is less than 180°. The three-blade model is 120. within. There are two gas paths on the stator. When the left cavity is inhaled, the starboard is exhausted, and the blades rotate counterclockwise under the lining of the compressed E gas, and vice versa.

Swing cylinders are widely used in industry at present, and are mostly used for rotating working parts whose installation position is limited to a rotation angle of less than 360°. WORLD Press Machine official website www.pressmachine-world.com, please indicate the source for reprinting!
