Description

TECHNICAL FIELD

[0001] The utility model relates to a tire production equipment field, concretely relates to a tool fixture for assisting in repairing bead crack. BACKGROUND

[0002] At present, with the rapid development of China's automobile industry, the demand for tires is getting larger and larger. The production of tires generally goes through the following steps: raw material preparation - rubber preparation and batching - tread and carcass manufacturing - semi-product manufacturing - molding - vulcanization - quality inspection and packaging.

[0003] Among them, the molding mainly refers to assembling the semi-finished products such as tread, carcass and cord fabric into a green tire (tire that has not been vulcanized, also called tire embryo) on a molding machine. The molding machine is divided into large-diameter and small-diameter molding machines, and the molding process is different due to the difference between the large-diameter drum and the small-diameter drum. After inspection, the green tire is transported to the vulcanization process for further processing.

[0004] The bead, also known as the tire lip or the bead, refers to the part of the tire inner edge in contact with the rim. It is made of rubber and usually wrapped with high-strength triangular rubber and steel wire ring structure. After inflating the tire, the tire lip can tightly buckle the rim to ensure the stable connection between the tire and the rim.

[0005] Due to various factors, the green tire bead may have cracks or bulges during molding. If not repaired, direct vulcanization will certainly affect the quality of the finished tire; but currently there is a lack of suitable tools in the factory, and the repair consumes a lot of time.

[0048] Specifically, the use method of the utility model is as follows:

[0049] When the tire bead has a crack, the operator first cleans the crack, then applies special glue to bond the crack; then the corresponding position of the tire bead with the crack can be placed in the H-shaped frame 110, the screw rod 120 is moved downward by rotating the screw rod 120, the distance between the upper pad 150 and the lower pad 160 is adjusted, the upper pad 150 and the lower pad 160 clamp the tire bead and slightly extrude the tire bead, so that the position of the tire bead is effectively fixed, the glue is more uniformly bonded to the crack, and the repair effect is improved. After the repair is completed, the next step of vulcanization can be normally carried out.

[0050] When the tire bead has a bulge or other deformation, for example, a single bulge in the local tire bead, first, the upper pad 150 and the lower pad 160 are disassembled according to the requirements; then the direction of the bulge is determined, the corresponding position of the tire bead with the bulge is placed in the H-shaped frame 110, the bulge is aligned with the rotating head 130 at the bottom end of the screw rod 120 (at this time, the bulge is located between the two top columns 140), then the screw rod 120 is rotated, the position of the rotating head 130 is adjusted, the distance between the bottom end of the rotating head 130 and the top column 140 is reduced, the bottom end of the rotating head 130 is pressed against the bulge, and the bulge is flattened in combination with the two top columns 140, so that the tire bead is gradually and uniformly corrected and restored to its original shape. After correction, the next step of vulcanization can be normally carried out.

[0051] The above is only an optional embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
