Description

Technical Field

[0001] The utility model relates to the technical field of tire molding devices, in particular to a radial non-pneumatic tire molding device. Background Art

[0002] The non-pneumatic tire uses elastic fillers or supports to replace the "air bag" structure of the traditional pneumatic tire, which is made of a composite of a skeleton material and a rubber laminated layer, to play the role of bearing, buffering and vibration reduction, and providing force. While in normal use, it avoids the safety hazards caused by air pressure loss or tire blowout during driving. However, non-pneumatic tires also have certain defects. The elastic support body is the main force-bearing structure of the tire. The uneven distribution will cause the phenomenon of uneven stiffness and ground stress during the rolling process of the tire, which will accelerate the wear of the tire body and reduce the service life of the tire. In the prior art, most of the support bodies need to be bonded to the rim and tread ring manually, so that the alignment of the processed tire has a certain deviation, and it is impossible to ensure that the support body and the rim and tread ring are bonded together synchronously. In addition, the large number of support bodies attached to the rim and tread ring have low precision in the circumferential direction, which makes the structure of the processed non-pneumatic tire uneven and the overall performance poor. In addition, when the bonding quality is poor, it is easy to cause bonding failure, which makes the support body very easy to fall off the rim and tread ring. Therefore, the uniformity of tire quality is difficult to ensure, the production efficiency is low, and it is not conducive to the mass production of tires. Utility Model Content

[0026] The specific implementation process of the utility model is as follows: the pre-glued rim 1 and tread ring 2 are arranged in place, the inner side of the glued support body 3 is installed in the wedge-shaped groove 11, and the inner ring boss 511 is sleeved on the outer peripheral surface of the rim 1. The inner ring boss 511 is passed through the support body 3 and inserted into the inner through groove 411 one by one to ensure that the support body 3 is accurately bonded to the rim 1. Then the outer wedge block 8 slides along the inner wedge block 7 to drive the outer positioning ring 6 to approach the tread ring 2, and finally slides into the outer through groove 412, and the embedded clamping protrusion 621 is tightly attached to the outer cylindrical table 43. The outer positioning ring 6 pushes multiple support bodies 3 at a time, so that the annular array distribution of each support body 3 is consistent with the spacing of the tread ring 2 and the force is uniform. The inner positioning ring 5 and the outer positioning ring 6 respectively give a certain abutment force to the inner end face and the outer end face of the support body 3, so as to achieve effective bonding between the two end faces of the support body 3 and the rim 1 and the tread ring 2 and make the support body 3 have a certain prestress. A certain prestress is conducive to improving the overall load-bearing capacity of the tire. The shapes of the inner through grooves 411 and the outer through grooves 412 arranged on the base 4 are consistent with the inner ring bosses 511 and 512. The shape of the outer ring boss 611 is adapted so that the inner positioning ring 5 and the outer positioning ring 6 do not rotate in the circumferential direction, the through groove 41 is not in direct contact with the ground, and there is a certain distance between them. The height of the inner ring boss 511 and the outer ring boss 611 can be greater than, equal to, or less than the depth of the through groove 41. The raised height of the outer cone 43 is greater than the axial length of the support body 3 to facilitate the outer connecting portion 62 to overlap the outer cone 43 without interfering with the shaping of the support body 3. When the outer wedge block 8 slides along the inner wedge block 7 to drive the outer positioning ring 6 to move to one side of the tread ring 2, the outer ring boss 611 is not in direct contact with the plane where the through groove 41 is located. The support body 3 passes through the inner positioning ring 5 and is inserted into the rim 1. After the inner positioning ring 5 is arranged close to the rim 1, it is completely fixed in the circumferential direction and the radial direction. The inner end face of the support body 3 is positioned in the radial direction together. A plurality of outer positioning rings 6 together constitute an annular structure with the axis of the base 4 as the center of the circle. The outer positioning rings 6 can be pushed sequentially or simultaneously to achieve the bonding of the support body 3 and the tread ring 2. The support body 3 is pre-placed one by one on the inner partition 51 and the outer partition 61 before the outer positioning ring 6 approaches the tread ring 2. In order to ensure the uniformity of bonding and the stability of assembly of the support body 3, when the outer wedge block 8 moves to the final position, the shapes of the gaps between the inner partitions 51 and the gaps between the outer partitions 61 match the support body 3, and a matching groove 81 matching the matching boss 71 is provided at the bottom of the outer wedge block 8, and an opening matching the size of the through hole on the outer connecting part 62 is provided at the upper part, which can conveniently control the positioning movement of the outer positioning ring 6 along the inner positioning ring 5, thereby avoiding the misaligned rotation of the support body 3 inserted therein, resulting in loosening and bonding failure.In addition, the outer wedge block 8 can start to move and extrude the support body 3 at the middle part of the inner wedge block 7, the inner positioning ring 5 is fixedly connected to the inner wedge block 7, the outer positioning ring 6 is fixedly connected to the outer wedge block 8, the inner positioning ring 5 and the inner wedge block 7 as well as the outer positioning ring 6 and the outer wedge block 8 can be connected by welding, one-piece molding, bonding or fixing with fixing parts, and the fixing parts can be rivets, screws, etc. When the bolt connection method is adopted, the bolts are threadedly engaged through the through holes opened in the positioning ring and the threaded holes opened in the wedge block.
