Abstract

The utility model discloses a special ring seat for nitrogen vulcanization of a vulcanizing machine central mechanism. The special ring seat for the nitrogen vulcanization comprises a seat body, wherein the seat body is provided with a high-temperature medium access passageway, backwater holes and a backflow water passageway which is communicated with the backwater holes. The high-temperature medium access passageway comprises two passageways which respectively are a steam access passageway and a nitrogen access passageway. The backflow water passageway is located between the nitrogen access passageway and the steam access passageway, and the three passageways are evenly distributed within 120 degrees. A plurality of backwater holes are arranged in the circumferential direction of the seat body and are evenly distributed. The seat body which is a forge piece is connected with a chuck plate through a flange structure and is sealed through a sealing gasket. The special ring seat for the nitrogen vulcanization is particularly suitable for nitrogen vulcanization tiers, enables vulcanizing temperature of a capsule to be even, and can satisfy requirements of a pipe distributing design more easily. The ring seat is connected with the chuck plate through the flange structure and increases the sealing area with the sealing gasket. The ring seat is formed by welding of a forge piece so that the problems of air leakage and water leakage of casting materials are solved effectively.

Description

The special-purpose ring seat of nitrogen sulfuration

(1) technical field:

The utility model relates to tire forming vulcanizer Type B central authority parts, is specially the special-purpose ring seat of a kind of nitrogen sulfuration.

(2) background technology:

The ring seat of tire forming vulcanizer Type B central authority is installed on the ring up-down water vat, and the ring seat connects chuck under the capsule through trapezoidal thread, finds in long-term the use, and the ring seat of traditional central authority is because the structure of self causes the appearance of more problem:

1, the ring seat has only a backwater hole, makes non-uniform temperature in the capsule easily, and temperature is lower when ponding, influences tire quality.

2, ring seat upper trapezoid screw thread needs to reject the wide thin position of afterbody tooth after processing, otherwise causes damage easily, makes the capsule chuck can't installation or removal and that capsule is installed is inconvenient.

3, the ring seated connection advances, the conduit connector of backwater is symmetry processing on the ring seat, when such ring seat uses on hydraulic pressure vulcanizing machine, and hydraulic tube close together during with the steam pipe installation, what have also can interweave, and makes oily temperature rise easily.

4, the sealing of O circle is adopted in the sealing of chuck under ring seat and the capsule, and O circle sealing damage easily causes leakage,

5, ring seat all is one and enters the hole; When vulcanizing with nitrogen; Nitrogen and steam spray to capsule from same group of spray-hole, owing to do not consider that nitrogen is different with the density of steam, make two kinds of gases cause the upper and lower non-uniform temperature of capsule when getting into; And two kinds of gases can not fully merge after getting into capsule, and the high temperature that when merging, occurs is also inhomogeneous.

6, existing all is casting material with the ring seat, and defectives such as burning into sand, pore appear in casting material easily, cause gas leakage.

(3) utility model content:

To the weak point of tradition ring seat, the purpose of the utility model is that a kind of capsule temperature that can make of design is even, is applicable to the nitrogen sulfuration, easy stringing, good seal, the special-purpose ring seat of nitrogen sulfuration easy to connect.

Can realize the special-purpose ring seat of nitrogen sulfuration of above-mentioned purpose; Comprise pedestal; Offer the high-temperature medium admission passage on the said pedestal; Backwater hole and the recirculation water passage that communicates with backwater hole, different is that said high-temperature medium admission passage is twice, is respectively steam admission passage and nitrogen admission passage.

Said recirculation water passage is between nitrogen admission passage and the steam admission passage, and the evenly distributions in 120 degree of three passages, and purpose is an easy stringing when being convenient to design, avoid simultaneously hydraulic tube and steam pipe near and make oily temperature rise.

For making the temperature in the capsule more even, said backwater hole is upwards offered a plurality of in pedestal week, and a plurality of backwater holes evenly distribute.

Said backwater hole is usually by four～six settings.

Said pedestal adopts flange arrangement to connect chuck under the capsule, and it is more convenient that capsule is installed, and has avoided trapezoidal thread to damage the connection that brings and has bothered.

Seal under the flange of said pedestal and the capsule between the chuck is a sealing gasket, and sealing area is increased, and is difficult for leaking.

Said pedestal is a forging, and the material compactness of forging is better, is difficult for gas leakage, drainage.

Said forging is last, the weldment of following two split forging.

The advantage of the utility model:

The special-purpose ring seat of the utility model nitrogen sulfuration is specially adapted to use the nitrogen vulcanized tyre, and can make the bladder curing temperature even, satisfies the stringing designing requirement more easily; Chuck adopts flange connection and uses sealing gasket under ring seat and the capsule, to increase sealing area; The ring seat adopts the forging welding, effectively solves gas leakage, the seepy question of former casting material.

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Fig. 2 is an A-A cutaway view in Fig. 1 embodiment.

Fig. 3 is a B-B cutaway view in Fig. 1 embodiment.

Figure number sign: 1, pedestal; 2, backwater hole; 3, recirculation water passage; 4, steam admission passage; 5, nitrogen admission passage; 6, plug; 7, sealing position; 8, flange.

(5) specific embodiment:

Be described further below in conjunction with the technical scheme of accompanying drawing the utility model.

The pedestal 1 of the special-purpose ring seat of the utility model nitrogen sulfuration is as shown in Figure 1, and the bottom of said pedestal 1 is installed in the support of ring up-down water vat, and cylinder cap is installed at the top of pedestal 1.

Like Fig. 2, shown in Figure 3; The middle part of pedestal 1 is the local ring body that increases, and is uniformly distributed with on the ring body to offer through hole and form flange 8, and the medial surface epirelief of flange 8 forms sealing position 7; Said flange 8 is provided with sealing gasket as the position that is connected of chuck under pedestal 1 and the capsule on the said sealing position 7.

Offer steam admission passage 4 and nitrogen admission passage 5 on the said pedestal 1; Circumference angle between steam admission passage 4 and the nitrogen admission passage 5 is 120 degree; Steam admission passage 4 is a recirculation water passage 3 with the 5 middle settings of nitrogen admission passage; Inwardly offer the backwater hole 2 that communicates with recirculation water passage 3 on pedestal 1 side face of flange 8 tops, backwater hole 2 quantity are six and evenly distribute, and are as shown in Figure 1.

The structure of said three passages is bottom outlet, apical pore and cross-drilled hole, and bottom outlet is offered in pedestal 1 bottom, and apical pore is offered in pedestal 1 top; Cross-drilled hole is radially offered in flange 8 side faces; Cross-drilled hole is communicated with apical pore and bottom outlet, and the aperture of cross-drilled hole blocks with plug 6 welding on flange 8 side faces, like Fig. 2, shown in Figure 3.

Steam and nitrogen get into from steam admission passage of pedestal 1 bottom 4 and nitrogen admission passage 5 respectively, and steam and nitrogen are from pedestal 1 top gets into the cylinder cap and the edge is different angle and direction are sprayed into capsule then; Cooling water in the capsule is summarized in recirculation water passage 3 through backwater hole 2, and discharges from pedestal 1 bottom, like Fig. 1, Fig. 2, shown in Figure 3.
