JPS59176031A - Squeezing ring of adhesive agent for manufacture of hose - Google Patents

Abstract

PURPOSE:To obtain the titled squeezing ring through which application of an adhesive agent is done evenly and dispersion of adhesive force between inside rubber and outside rubber is reduced, by a method wherein the titled squeezing ring is constituted by providing a hollow lip part is provided on the back of a base in a specific shape and providing a protruded part at a root part of the lip part. CONSTITUTION:A squeezing ring of an adhesive agent for manufacture of an aimed hose constituted by providing a hollow lip part 10 made of thin silicone rubber having the smoothly reducing inner diameter on the fringe of a hollow part 12 of the back of a hollow base 9 having the inner diameter which reduces smoothly extending from the front to the back and providing a protruded part 11 on the external circumference of a root part 13 of the lip part 10.

Description

[Detailed description of the invention] The present invention relates to adhesive wrinkle killing for hose manufacturing.

First, the manufacturing process of the hose will be outlined based on Figure 1.

Dr. l The process is to attach the inner surface of the mandrel 2 to the inner comb 3.
form. Next, the support thread 5 is braided onto this inner rubber 3''. Next, an adhesive is applied to the inner surface rubber 3 on which the reinforcing threads 5 are plated, and an outer surface rubber is further formed on the inner surface rubber 3. In this way, the hose 7 is manufactured. In this step, the embossed ring 8 is used between the application of the adhesive and the formation of the outer rubber, ie, in the step indicated by A in FIG. This is to make the applied adhesive uniform and to fill the adhesive between the meshes formed by the reinforcing threads 5.

Conventionally, this type of shibokiling is known as shown in Figures 5't, 1 and 2. That is, the first
The Shibo Killing ring 8 shown in the figure has a hollow part, the inner diameter of which decreases linearly from the front surface to just before the rear surface, and from there to the rear surface is the outer diameter of the inner rubber 3 on which the reinforcing thread 5 is braided. is almost the same. The Shiboki ring 8 shown in Fig. 2 also has a hollow part 12, and its inner diameter decreases in a lining-like manner from the front surface to a little before the rear surface, and from there to the rear surface, like the one in Fig. 1, there is a reinforcing thread. 5 is approximately the same as the outer diameter of the bladed inner rubber 3.

However, this type of conventional shibokiling has the following drawbacks. In other words, if the outer diameter of the inner rubber 3 becomes smaller than the inner diameter of the hollow part of the wrinkle ring, the adhesive will be applied unevenly, and the adhesive will not penetrate into the mesh formed by the reinforcing threads. ikj becomes insufficient. As a result, the adhesion between the inner rubber 3 and the outer rubber decreases. At the same time, variations in electrodeposition strength occur.

The purpose of the present invention is to improve the drawbacks of this type of conventional Shibo Killing, and the Shibo Killing of the present invention has a hollow base having an inner diameter that decreases smoothly from the front surface to the rear surface; A thin hollow lip portion provided on the periphery of the hollow portion and having a smoothly decreasing inner diameter; a protruding portion provided on the outer periphery of the root portion of the lip portion;
This is Shibo Killing, an adhesive for hose manufacturing.

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 4 and 5 are cross-sectional views showing the Shibo Killing ring according to this embodiment.

(The part 9 has an inner diameter that smoothly decreases from the front surface to the rear surface, and is hollow inside.The shape of the outside is arbitrary.

A lip portion 10 is provided at the periphery of the hollow portion 12 on the rear surface of the base portion 9 . The lip portion 10 is thin and hollow. The inner diameter of the base portion 13 is the same as the inner diameter of the hollow portion 12 on the rear surface of the base portion 9, and the inner diameter of the tip portion 14 is slightly smaller than the outer diameter of the inner rubber. From root part 13 to tip part 1
It decreases smoothly from 4 onwards. The lip portion 10 may be integrally molded with the base portion 9. Moreover, the material is preferably silicone rubber from the viewpoint of oil resistance.

A protruding portion 11 is provided on the outer periphery of the root portion 13 of the pump portion 1O. This is to make the lip portion 10 retain its elasticity. That is, it is for applying compressive force to the hose via the lip portion 10.

Since the present invention is constructed as described above, the adhesive can be applied uniformly, and even if the outer diameter of the hose after the blade varies, the adhesive can be applied uniformly. As a result, variations in the electrodeposition strength between the inner and outer rubbers were reduced. Comparing this with the conventional example, the first
Shown in the table.
