JPS6030315A - Spouting outlet member of inner pressure medium for tyre press - Google Patents

Abstract

PURPOSE:To obtain the spouting outlets being able to heat or cool rapidly without the temperature difference between each part of a tyre by providing a plurality of spouting outlets directed to three dimensional directions up and down and right and left. CONSTITUTION:A passage 23 is provided in the bag cylinder 7 through which a piston rod 8 passes slidably freely (a sign 22 is the feeding path of inner pressure medium for a tyre press). For this passage 23, from an upper stage to a lower stage, a plurality of spouting outlets 25, 26, 27,...33 (inner diameter: about 6mm., mutual distance: about 15-20mm.) for inner pressure medium, are arranged such that the flying locus of the inner pressure medium spouted therefrom is directed into three dimensional space. Thus, the spouting outlet member 21 is formed. Said member 21 is arranged in the tyre 3 (sign 4 is bladder) provided is a mold, placing the tip portion of said member 21 at a little lower position than the central line C of the tyre and is used. The inner pressure medium is spouted from a plurality of said spouting outlets and is caused to flow in the tyre so as to be shown by stream line Y, whereby the tyre 3 is heated or cooled uniformly.

In addition to supporting the plug 4 that presses the tire 3 from the inside,
It is disposed in the lower clamp ring 6 of the lower clamp rings 5 and 6, is fixed to the bug cylinder 7 with a screw, is slidably passed through the piston rod 8 of the bug cylinder 7, and also serves as a gland. It has a so-called 20 structure, which has a spout 11 facing in the horizontal direction and one discharge port 12 facing in the horizontal direction.
The internal pressure medium is ejected in a horizontal plane from the inner pressure medium to heat or cool the tire 3 via the plug 4, and the internal pressure medium is discharged from the discharge port 12.

じ、重大な問題となっていた。However, since the internal pressure medium outlet member 1 has one outlet 11 and one outlet 12, and they face in the horizontal direction, For items with a large section width W, such as race tires and tires for industrial vehicles, even if hot water or cooling water is sprayed from below, the spray will be flat.
As shown by arrow A in Figures 1 and 3, uniform circulation cannot be obtained upward, and the cooling or heating effect in the upper part shown by arrow B in Figure 3 is slow, resulting in the temperature of the upper and lower parts of the cartire 3. There was a drawback that it became uneven. Particularly in the case of nylon tires, etc., which require a cooling process, such insufficient cooling effect causes a decrease in the strength of the yarn, deformation of the tire, etc., which has become a serious problem.

冷却又は加熱でトることが分かる。According to the internal pressure medium outlet member 21 configured as described above, the internal pressure medium protrudes to the vicinity of the center line C of the tire, as shown in FIG.
Since it is ejected from 7... in all three-dimensional directions,
As shown by the streamline Y in FIG. 5, the internal pressure medium flows evenly over the entire area within the bladder 4 even for the wide tire 3 in the section, and there is no flow, so the bladder 4 is Heat or cool the tire 3 quickly through the outside,
Moreover, each part of the tire 3 can be heated or cooled evenly. FIG. 8 shows an example of a performance comparison experiment between the above-described air outlet member 21 and the conventional air outlet member 1 shown in FIG. 1. The curve M in FIG. 8 represents the temperature measurement result of the portion D of the tire 3 (see FIG. 5) when the air outlet member 21 of this embodiment is used.
A curve N in FIG. 8 shows the result of measuring the temperature of a portion D of the tire 3 (see FIG. 3) using the conventional air outlet member 1 shown in FIG. 1. From the curves M and N, it can be seen that this embodiment can be cooled or heated more quickly and effectively than the conventional one.
