The invention discloses an extruder oil cylinder piston rod and a novel oil cylinder structure. The piston rod comprises a piston rod body, wherein a connecting through hole is formed in the front end of the piston rod body; a slide bearing is inserted in the connecting through hole; the outer wall of the slide bearing is fixed on the inner wall of the connecting through hole; a hinge shaft is inserted in the slide bearing; the two ends of the hinge shaft extend outside the connecting through hole to form radial edges; screwing sections are formed at the two ends of the hinge shaft; a hinge plate is screwed on the screwing sections; the screwing sections are screwed with two locking nuts; the hinge plate is clamped between one locking nut and the radial edges; and the bottom end of the piston rod body is inserted on a piston head. An oil cylinder adopting the extruder oil cylinder piston rod comprises a cylinder body, wherein the cylinder body consists of a side wall cylinder and a cylinder bottom; the cylinder bottom is screwed on the side wall cylinder; the piston rod body and the piston head are inserted in the cylinder body; the length of the piston rod body can be changed as required to satisfy requirements; and meanwhile, the cylinder body adopts a split structure, so that the disassembly and the maintenance are convenient.
Description
Technical field: [0001] The invention relates to the technical field of extruders, in particular to a novel structure of a piston rod and an oil cylinder of an extruder oil cylinder. Background technique: [0002] The existing oil cylinder piston rod is generally integrated, and it cannot be adjusted in length. At the same time, the cylinder body of the existing oil cylinder is an integrated cylinder body, which is difficult to maintain and disassemble. When it is damaged, it can only be replaced as a whole, and its maintenance cost high. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a new structure of the piston rod and the oil cylinder of the extruder oil cylinder. The length of the piston rod body can be changed according to the needs to meet the needs. The utility model has the advantages of convenient disassembly and maintenance, low maintenance cost and good effect. [0004] The scheme...
