The expansion cylinder 7 performs a contraction movement, and drives the sidewall expansion 4 to move closer to the right bead transfer ring 32 along the slide rail 11 at the top of the frame 1, so that the claw portion of the L-shaped expansion claw 42 penetrates into the interior of the carcass assembly. The L-shaped extension jaws 42 then undergo a radial expansion motion under the action of the drive to expand the edges of the carcass assembly. The carcass assembly is fed into the molding under the combined action of the retaining action of the carcass tile 22, the pinch adsorption of the bead transfer ring 31/32, and the expansion of the cylinder port of the carcass assembly by the L-shaped extension claw 42. When the drum is in position, it is sleeved on the outer circumference of the forming drum. After the carcass assembly is completely placed on the forming drum, the L-shaped expansion claw 42 performs a radial contraction movement, and then the expansion cylinder 7 is extended to move the side reinforcing ring 4 away from the right bead transfer ring 32. Finally, the L-shaped expansion claw 42 performs a radial expansion movement, the carcass tile 22 moves in a direction away from the center of the carcass assembly, the adsorption pad 331 expands radially while the clamping claw 332 releases the left and right beads, in the frame. The entire carcass assembly transfer device leaves the forming drum under the action of 1.
