Abstract
A method for manufacturing a hydraulic accumulator bladder includes the following steps: bonding a rubber sheet to the gas-filled air bladder to form a bladder blank; placing the bladder blank in a vulcanization device for vulcanization to form an initial bladder product; and releasing the gas in the gas-filled air bladder of the initial bladder product, taking the air bladder out, and naturally cooling the initial bladder product to a room temperature to form a finished bladder product. The bladder manufactured by the manufacturing method is integrally formed by one-step vulcanization, and has the advantages of uniform wall thickness, smooth inner and outer surfaces, long fatigue lifetime, a simplified process, high quality and good stability.
