Compression roller with compression roller curve matched with steel ring compression face and method for compressing steel ring wrapping fabric

Abstract

The invention discloses a compression roller with a compression roller curve matched with a steel ring compression face, and a method for compressing a steel ring wrapping fabric. The method comprises the following steps of: firstly, designing a steel ring compression roller curve according to the shape of the cross section of a steel ring structure, wherein the steel ring consists of steel wires, a triangular adhesive tape and the wrapping fabric and is in the shape of a trapezoid, and the upper bottom and the inclined lines of the trapezoid consist of multiple sections of lines; secondly, placing the semi-finished steel ring on which the triangular adhesive tape is stuck on a station of a steel ring wrapper, and placing the steel ring wrapping fabric at the bottom of the steel ring according to a construction process requirement; and finally, opening an air pipe controlling and compressing valve, wherein under the action of certain air pressure, a novel compression roller curve clings to the steel ring wrapping fabric to roll and compress and compact the semi-finished steel ring and the steel ring wrapping fabric, exhaust air at the same time and overcome defects caused by internal clearances. The improved steel ring compression roller curve is adopted, so during rolling compression, the contact face between the compression roller and the steel ring is effectively increased, the problem of air bubbles in the steel ring is solved, and the quality of a tire is improved.

Description

technical field [0001] The invention relates to tire manufacturing, in particular to a pressing roller whose curve matches the pressing surface of a steel ring and a method for pressing the wrapped cloth of the steel ring. Background technique [0002] The steel rim is an important part of the tire and the main skeleton of the tire. It plays a very important role in the use process, such as carrying weight and obtaining kinetic energy for driving. Pressing the wrapped steel ring with the pressure roller of the original steel ring wrapping machine has the following disadvantages: [0003] 1. The pressure roller only presses to one point of the steel ring, and the whole circle becomes linear; [0004] 2. The steel ring cloth is not close to the steel ring, and it is twisted; [0005] 3. There are many air bubbles inside the steel ring. Contents of the invention [0006] Aiming at the deficiencies of the prior art, the invention provides a pressing roller whose curve match...
