Method and device for manufacturing rubber bend pipe |
摘要 |
A method for manufacturing a curved rubber pipe is provided with a guide member (3) arranged concentrically with a mandrel (2, 402). A straight rubber semi-finished product (4) of an unvulcanized or semi-vulcanized rubber is inserted into the guide member (3). A die lubricant can be applied only to the inside of the rubber semi-finished product (4) over its whole length. The rubber semi-finished product (4) is fitted on the mandrel (2, 402) by pushing the product by a head (7) mounted on a leading end of an arm (6). One end of the curved rubber pipe (1) is gripped after vulcanizing by a gripping member (10) and is extracted from the mandrel (2, 402). By this method, it is possible to fit and smoothly extract the rubber semi-finished product (4). The method can also easily be automated.
