Embodiment Construction

[0025] Such as figure 1 As shown, the pneumatic actuator structure used for cable production in the present invention includes a short cylinder body 1, a hollow box body 2 and a long cylinder body 3, and the two ends of the hollow box body 2 are respectively connected with the long cylinder body 3 and the short cylinder body 1 by screws connect.

[0026] The short cylinder block 1 includes an intake cylinder head 4 , a cylinder barrel 5 , a limit cylinder head 6 , a limit post 7 , a piston 8 , a piston rod 9 and two guide posts 10 penetrating the piston 8 . The two ends of the cylinder barrel 5 are respectively welded with the intake cylinder head 4 and the limit cylinder head 6. The piston rod 9 passes through the piston 8 and is fixed by a hex nut. The edge of the piston 8 is embedded with an O-ring, and the piston 8 is also There are two through holes for the guide column 10 to pass through the piston 8, and O-ring sealing rings are embedded on the walls of the through hol...

Abstract

The invention discloses a pneumatic actuator structure for cable production. The pneumatic actuator structure for the cable production overcomes the defect that by the adoption of an existing single-action actuator, a piston rubs a cylinder. The pneumatic actuator structure for the cable production comprises a short cylinder block, a hollow box and a long cylinder block. The two ends of the hollow box are connected with the short cylinder block and the long cylinder block correspondingly. A piston and a piston rod are arranged in the short cylinder block. A crank and a rotating shaft used for being connected with a valve are arranged in the hollow box. The rotating shaft is detachably connected with the crank. The rotating shaft penetrates the hollow box. An elastic piece seat, and elastic piece and a pull rod capable of moving in the long cylinder block are arranged in the long cylinder block. The pull rod is detachably connected with the elastic piece seat. The pull rod is sleeved with the elastic piece. Guide columns are arranged in the short cylinder block and penetrate the piston. A sliding block is arranged on the crank and connected with the crank in a sliding manner. The piston rod and the pull rod are detachably connected with the sliding block. A guide rod is arranged in the hollow box and penetrates the sliding block. The pneumatic actuator structure for the cable production has the advantages that the piston moves stably, the piston does not rub the cylinder, and the structure is simple.

Description

technical field [0001] The invention belongs to the actuator field of a fluid pipeline regulating valve in a power system during the cable production process, and in particular relates to a pneumatic actuator structure for cable production. Background technique [0002] Generally, the production process of cables includes the steps of manufacturing metal rods / plates, drawing, annealing, stranding and bundles of wires, and wrapping shielding layers. In the annealing step, in order to improve the performance of the conductor, running water annealing (annealing with flowing water) is usually required. In order to control the fluidity of running water, valves are usually installed on the running water pipes, and the degree of opening and closing of the valves is controlled by corresponding actuators. Current actuators are mainly single-acting actuators. [0003] At present, the single-acting actuator mainly includes a cylinder, a box body and a long cylinder. The two ends of ...
