【発明の詳細な説明】
(発明の技術分野)
本発明は大径サイズの鉄心入pOりングのようなゴムバ
ッキングを製造する方法に関する。TECHNICAL FIELD OF THE INVENTION The present invention relates to a method of manufacturing rubber backings, such as large-diameter size iron-core PO rings.
(発明の技術的背景)

形する方法が行なわれてい良。(Technical Background of the Invention) Conventionally, in order to manufacture a rubber backing in which a ring-shaped iron core with a large diameter of 1,500 to 2,200 mφ is encased, the iron core is made of an unvulcanized rubber body that has been extruded into a ring shape in advance. A good method is to encapsulate it, load it onto gold 11, heat and pressurize it, and vulcanize it.

しておき、鉄心の偏心1防ぐ方法も行なわれて%Aえ。1. When covering the iron core with the unvulcanized rubber body, a method of preventing the eccentricity of the iron core is carried out by placing aluminum pieces in advance at positions divided by 16 parts of the outer circumference of the iron core.
(背景技術の問題点)
しかしながらこれらの方法では、以下に記載する理由に

できなかった。(Problems with the Background Art) However, with these methods, it is difficult to hold the iron core in the center of the rubber body for the reasons described below, and it has not been possible to manufacture a rubber backing with an iron core without eccentricity.

い。In other words, a) Since the large-diameter steel core is manufactured by processing the curved steel bar, it is difficult to process the diameters of each part to be equal and close to a perfect circle, and the pressure during vulcanization molding is difficult. The iron core itself is more susceptible to deformation 1.Q) The additional value rubber coated with YAK around the core cannot be made completely constant over the entire circumference, so the rubber becomes layered after one vulcanization cycle. In this case, the internal pressure of each rubber part becomes uneven, and the iron core tends to move to the side where the pressure is lower.

ることが難しい。(3) With a large pressure device, it is difficult to apply uniform pressure to the entire metal lid.
等の理由により鉄心の偏心が生じやすいという問題があ
った。There was a problem that eccentricity of the iron core was likely to occur due to the following reasons.

目的とする。(Object of the Invention) An object of the present invention is to solve such problems and to provide a method for manufacturing a large-diameter iron-core rubber ring assembly with less eccentricity.

方法Kllする。(Overview of the invention 1!) The present invention provides a semi-vulcanized rubber layer at a predetermined position around a large ring-shaped iron core, and then covers the outside with a backing body made of unvulcanized rubber. The whole is loaded into the cavity of a mold, heated under pressure, and integrally vulcanized and molded to form a T-S mold.

少なめとしておく。In the present invention, first, on a ring-shaped iron core 1 obtained by processing by a conventional method and having a cross section of approximately circular with a diameter of 13 mm and a diameter of 1500 mm, the circumference is divided into 11:8 to 16. The pre-molded layer 2'keFj is made of the same rubber as the body in the vulcanized state for 70 s@f. At this time, the thickness of the pre-mold layer 2 is set to be slightly smaller than the thickness of the rubber part to be molded.

After this, pressure is applied to the mold to determine whether there is too much or insufficient rubber in the cavity, and it is desirable to adjust this with a wound layer of unvulcanized rubber. The rubber body 6, the pre-mold layer 2, and the unvulcanized rubber tape wound layer are integrally vulcanized and molded by heating in a vulcanization temperature box while applying the heat.
