Abstract

The invention provides a tire building drum, which can solve the tire quality problems in the prior art that there are too deep indentations on the sidewall after the tire is turned up, and the rubber material on the sidewall part is uneven after inflation. The tire building drum includes the main shaft, the lock block assembly and the turn-up device. The turn-up device includes a plurality of turn-up rods. The front end of the turn-up rod is equipped with a turn-up roller. The lock block assembly and the multiple turn-up rods of the corresponding side turn-up device The upper sleeve is provided with the same tubular flexible covering, the front end of the flexible covering is fastened to the lock block assembly, and the rear end is connected to the turn-up device. When the turn-up device is turned up in place, the front part of the flexible cover is completely closed. Fits over the sidewall of the tire. By setting the flexible covering, it is possible to avoid the direct extrusion of the turnup bar roller to the sidewall rubber, and it can buffer the extrusion force of the roller, reducing the extrusion force of the turnup bar roller on the sidewall rubber. Reduce the indentation on the sidewall after the tire is turned up, and improve the quality of the tire.

Description

Technical field [0001] The invention belongs to the technical field of rubber machinery, and specifically relates to the structural improvement of a tire building drum used for tire turn-up operations. Background technique [0002] In the rubber tire manufacturing process, the building drum on the tire building machine is mainly used for the turn-up of tire sidewall rubber. [0003] In the prior art, the forming drum generally includes a hollow cylindrical main shaft with left and right-rotating roller screws inside. The outer circumference of the main shaft is sleeved with a lock block assembly and a turn-up device. The lock block assembly is used for The tire is locked and positioned during turn-up. The turn-up device is used to turn-up the sidewall rubber. At the same time, the lock block assembly and the turn-up device are two sets, which are symmetrically arranged on the vertical center line of the main shaft to lock the two sidewalls of the tire. And anti-packaging. Among t...
