Problems solved by technology

[0002] During the tire building process, the irregular parts of the tire shoulder and bead (including pad rubber, sidewall, and lower rubber core) are prone to misaligned positioning during the pressing process. How to ensure the pressing quality of the parts is an operational problem. certain degree of difficulty
And when the part is skewed or not dense, there is no good inspection method to effectively identify it, which will eventually cause fluctuations in the uniformity of the service life of the tire and affect the use of consumers

Embodiment 1

[0030] The present invention provides a method for ensuring the pressing quality of special-shaped parts in the molding process. Figure 1-2 a point in ), the inner endpoint ( Figure 1-2 point b in ) to the outer endpoint ( Figure 1-2 d point) in the order of pressing.

[0031] During the pressing process of the rubber pad part 1 and the sidewall part 2 on the drum, the lower pressing roller is pressed outward in the axial direction when the drum rotates. At this time, the track of the pressing roller on the pressed part is in a spiral shape. Due to the irregular shape of the cushion rubber part 1 and the sidewall part 2, the outward thrust generated by the pressing roller during the pressing process is obviously greater than that when the components are fitted due to the change of the thick and thin points of the components and the helical pressing track. Adhesion, resulting in localized misalignment of parts when pressed together. The thickest point of the part is used ...

Embodiment 2

[0046] On the basis of Example 1, it also includes the confirmation of the lower rubber core part 3 after pressing: the structure of the lower rubber core part 3 before pressing is as follows: Figure 5 As shown, the structure after pressing is as follows Image 6 Set the width of the lower rubber core part 3 after pressing, move the positioning laser light mark to the set position according to the width, and measure the distance between the outer thinnest end point of the lower rubber core part 3 and the positioning laser light mark If the distance meets the preset standard 2, it is determined that the lower rubber core part 3 meets the requirements for pressing; if the distance does not meet the preset standard 2, the lower rubber core part 3 is re-pressed after adjusting the pressing parameters. Wherein, the second preset standard is: distance≤10mm.

[0047] By the method of this embodiment, the pressing quality of the lower rubber core part 3 during the pressing process c...

Abstract

The invention discloses a method for ensuring the pressing quality of special-shaped parts in the molding process, and belongs to the technical field of construction machinery tire manufacturing. The technical scheme is as follows: when the cushion rubber component and the sidewall component are pressed together, the pressing is performed in the order of the thickest point, the inner end point and the outer end point of the components. The present invention designs the traveling mode of the pressing roller, which can avoid the abnormal material deviation of the pad rubber and the sidewall components during the pressing process, ensure the conformity of the positioning of the components, and reduce the early quality problems in the market.

Description

technical field [0001] The invention relates to the technical field of construction machinery tire manufacturing, in particular to a method for ensuring the pressing quality of special-shaped parts in the molding process. Background technique [0002] During the tire building process, the special-shaped parts (including the pad rubber, sidewall, and lower rubber core) of the tire shoulder and bead part are prone to the problem of skewed positioning during the pressing process. How to ensure the pressing quality of the parts exists in the operation. certain difficulty. And when the component is skewed or not dense, there is no better inspection method to effectively identify it, which will eventually cause fluctuations in the uniformity of tire service life and affect the use of consumers. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a method for ensuring the pres...
