Technical Field

The invention relates to auxiliary equipment for radial tire production, in particular to an elastic compression roller for radial tire molding.

Background

In the production process of the radial tire, a belted layer is wound around a forming machine head layer by layer, in the winding process, the belted layer close to the edge of the machine head needs to be bent and wound back, and the edge belted layer is warped and shifted under the combined action of pulling force to influence the forming.

Disclosure of Invention

The invention aims to provide an elastic press roll for radial tire molding, aiming at the defects in the prior art. The compression roller can effectively press the belted layer in the radial tire forming process, prevents the belted layer from upwarping and shifting, can also realize elastic pressing, can adapt to belted layers with different thicknesses, and has simple structure and low cost.

The technical scheme for realizing the purpose of the invention is as follows:

an elastic press roller for forming a radial tire comprises a bracket and a press roller unit arranged on the bracket, the compression roller unit comprises a square shaft, a first blind hole group and a second blind hole group are respectively arranged at two ends of the square shaft, a first compression spring and a second compression spring are respectively arranged at each blind hole in the first blind hole group and each blind hole in the second blind hole group, one end of each of the first compression spring and the second compression spring extends out of the square shaft, a first core ring and a second core ring are respectively sleeved outside the square shaft at the positions of the first compression spring and the second compression spring, a first deep groove ball bearing and a second deep groove ball bearing are respectively sleeved on the outer walls of the first core ring and the second core ring, a first sleeve and a second sleeve are respectively sleeved at two end parts of the square shaft, the inward end of each of the first sleeve and the second sleeve is respectively in close contact with the outermost first core ring and the second core ring, and a third sleeve is sleeved on the square shaft between the adjacent first core ring and the second core ring.

One of them plane edge of first core circle is equipped with outside turn-ups, and turn-ups's width is 1mm, and second core circle is the same with first core circle specification, and the turn-ups is used for preventing axial displacement after first deep groove ball bearing and the assembly of second deep groove ball bearing.

The support comprises a first support plate and a second support plate which are arranged at intervals, a third support plate is arranged between the same end heads of the first support plate and the second support plate, a 45-degree fourth support plate is arranged on one side of a connecting portion of the first support plate and the third support plate, the connecting end of the fourth support plate and the first support plate extends out of the first support plate, a 45-degree fifth support plate is arranged on one side of a connecting portion of the second support plate and the third support plate, the connecting end of the fifth support plate and the second support plate extends out of the second support plate, the fourth support plate and the fifth support plate are located on the same side of the first support plate and the second support plate, a first baffle parallel to the first support plate is arranged at the extending end of the fourth support plate, and a second baffle parallel to the second support plate is arranged at the extending end of the.

The square shaft is positioned between the first baffle and the second baffle, and the ends of the two ends of the square shaft are respectively abutted to the first support plate and the second support plate.

The inner wall of the first deep groove ball bearing is in clearance fit with the outer wall of the first core ring, and the inner wall of the second deep groove ball bearing is in clearance fit with the outer wall of the second core ring.

The first deep groove ball bearing and the second deep groove ball bearing are 1000806 in model number.
