Problems solved by technology
The above-mentioned turn-up operation process has the following disadvantages: the pressing force of the turn-up bar on the embryo side decreases in the early stage, and gradually increases in the later stage, resulting in uneven stress on the embryo during the whole turn-up process; the centrifugal force of the forming drum rotation is easy when the turn-up has not started. Drive the turn-up rod to expand, so that the turn-up rod is easy to hit the surrounding equipment; after a long time of use, the turn-up rod is also easy to be thrown out under the action of centrifugal force and hit other equipment and break, affecting the use of the turn-up rod Lifespan and performance of peripheral equipment

The application belongs to the field of tire processing equipment, and discloses a pressure control device for a turn-up rod of a mechanical forming drum, which includes a main shaft and two side drums symmetrically arranged left and right on the main shaft. The side drums can move left and right along the main shaft to fix the embryo , each side drum is equipped with a group of turn-up rods distributed radially, one end of each turn-up rod is hinged to the corresponding side drum, and the other end is provided with a turn-up roller for turning up the embryo. Including: a belt, set on the circumferential outside of each set of turn-up rods to restrain the turn-up rods; a pressure compensator, installed on each side drum, and the pressure compensator is used to drive the other end of the turn-up rods to expand outwards to Make the turn-up roller move along the side wall of the tire embryo to perform the turn-up operation; wherein, during the turn-up operation, the pressure compensator provides pressure F1 to the turn-up rod, and the belt provides pressure F2 to the turn-up rod, and the pressure F1 and the pressure The sum of F2 is within the preset range. The application can improve the problem of uneven stress on the embryo during the turn-up process.
Description
technical field [0001] The application belongs to the technical field of tire processing equipment, and in particular relates to a pressure control device and control method for a turn-up rod of a mechanical forming drum. Background technique [0002] The turn-up process of the sidewall in the embryo forming process is a key link that affects the quality of the embryo and the molding efficiency. At present, the mainstream turn-up technologies mainly include capsule turn-up, mechanical turn-up and twist-pull turn-up. The efficiency of mechanical turn-up is compared with Because the other two turn-up methods are higher, especially the semi-steel forming machine has higher requirements for forming efficiency. [0003] The existing sidewall mechanical turn-up method mainly drives the turn-up rods on both sides of the tire to move closer to the middle. One end of the turn-up rod swings around the hinge point, and the other end can be opened like an umbrella when it touches the ti...
