And a spot welding method is adopted between the large flange and the core barrel. The fixing method of spot welding has the following defects: 1. the welding is not firm, and cracking is easy to occur; 2. when the steel cord is used, the gap between the large flange and the core barrel is easy to clamp, so that the steel cord is broken, and the production is influenced; 3. the spot welding easily causes uneven arrangement when the steel cord is wound, and the production efficiency is affected. The existing large flange structure for the spool cannot implement full-length welding because the joint of the disc and the cylindrical surface is not a plane.
In order to ensure concentricity of the large flange and the small flange, the structure of the large flange needs to be changed correspondingly and simultaneously when the structure of the large flange is changed.
The utility model comprises the following steps:
in order to remedy the defects, the utility model discloses the small flange for the spool, and the welding end face combination part is matched with the welding end face of the large flange, so that the concentricity of the large flange and the small flange is ensured, full welding between the large flange and the core barrel can be realized, and the beneficial technical effects of firm welding, difficult wire clamping, flat steel cord arrangement and the like are further brought. The utility model discloses a small flange for an I-shaped wheel, which comprises a small disc and a circular protruding part, wherein a reinforcing rib is punched outwards on the small disc, a welding end surface combining part is arranged on the small disc, the welding end surface combining part is arranged at the joint of the small disc and the circular protruding part, and the welding end surface combining part is of a circle of circular plane structure.
The preferable technical scheme is as follows: the welding end face joint part is of a round plane structure with the width of 1-3 mm.
The preferable technical scheme is as follows: the welding end face combination part is matched with the welding end face of the large flange. The preferable technical scheme is as follows: and 12 reinforcing ribs are uniformly arranged on the small disc.
The preferable technical scheme is as follows: the reinforcing ribs are arranged on the outer side of the welding end face joint part.
The preferable technical scheme is as follows: the reinforcing ribs are matched with the reinforcing ribs on the large flange.
According to the utility model, the welding end face joint part is arranged on the small disc, and the welding end face joint part is of a round plane structure with the width of 1-3 mm. The welding end surface joint part is matched with the welding end surface on the large flange, so that full welding between the large flange and the core barrel is realized while concentricity of the large flange and the large flange is ensured. And further brings the following technical advantages: 1. the large flange and the small flange are tightly matched, so that concentricity is ensured; 2. the large flange and the core barrel are welded through full welding, so that the welding is firm and the cracking is not easy to occur; 3. the large flange and the core barrel are welded through full welding, so that the spool cannot be clamped when in use, and the production efficiency is improved; 4. the steel cord is guaranteed to be arranged smoothly when being wound up through full-length welding, and production efficiency is improved.
