Description

Technical Field

[0001] The utility model relates to the technical field of tire processing equipment, and particularly relates to an impact-proof vulcanization capsule chuck. Background Art

[0002] At present, in the process of tire production, the vulcanization process is the last process of tire production. For the production methods using high-temperature and high-pressure steam and superheated water as vulcanization media, such as Figure 1 and Figure 2 shown, the principle is that the tire blank is sleeved on the vulcanization capsule 3, and steam and superheated water are sequentially introduced into the vulcanization capsule 3 to provide heat energy for vulcanizing the tire; during the vulcanization process, the high-temperature and high-pressure steam and superheated water entering the vulcanization capsule 3 have a greater impact force on the impact point 7 on the upper side of the vulcanization capsule 3 after being refracted by the upper chuck 1. After being used for a period of time, the vulcanization capsule 3 is prone to having thin spots on the upper side axially due to long-term high-temperature and high-pressure impacts, and finally the vulcanization capsule 3 is damaged, so that the vulcanization medium leaks into the tire blank, resulting in abnormal vulcanization and waste products. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an impact-proof vulcanization capsule chuck, which can reduce the refraction and splashing of the vulcanization medium by arranging buffer holes on the bottom surface of the upper capsule chuck, and at the same time, add a buffer baffle on the outermost side of the upper capsule chuck to increase the blocking and buffering effect of the upper capsule chuck on the impact of the vulcanization medium, and reduce the destructive force of the vulcanization medium on the impact point.

[0004] The utility model includes an upper chuck and a lower chuck which are oppositely arranged. A vulcanization capsule is fixed between the upper chuck and the lower chuck. A plurality of buffer holes are arranged at intervals on the bottom surface of the upper chuck. Outside the buffer holes, a baffle protruding towards the lower chuck is arranged in a surrounding manner.

[0005] Preferably, the buffer holes are arranged at intervals in a surrounding manner on the bottom surface of the upper chuck with the center of the upper chuck as the center of the circle, and enclose several circular ring shapes with different diameters.

[0006] Preferably, the cross-sectional shape of the buffer hole is an inverted trapezoidal structure with a narrow bottom and a wide top.

[0007] Preferably, the bottom surface of the upper chuck is an inclined surface inclined from the periphery to the center, and the buffer holes are located on the inclined surface.

[0008] Preferably, the cross-section of the baffle is a crescent shape curved towards the inside of the baffle.

[0009] Preferably, the baffle is integrally formed with the upper chuck.

[0010] In summary, the utility model has the following beneficial effects:

[0011] 1. A buffer hole is provided on the bottom surface of the upper chuck. The cross-section of the buffer hole is an inverted trapezoid. The vulcanization medium enters the vulcanization capsule from the liquid inlet, heats the vulcanization capsule, and the vulcanization medium sprays onto the bottom surface of the upper chuck from the liquid inlet. Utilizing the structure of the buffer hole, it diffuses around the upper chuck at a relatively slow speed and with a relatively gentle impact force, reducing the refraction and splashing of the vulcanization medium, and reducing the refraction flow rate and impact force of the vulcanization medium on the two-side vulcanization capsules.

[0012] 2. An annular baffle is provided around the buffer hole. The baffle is a crescent shape bent inward. For the vulcanization medium refracted from the buffer hole to both sides, it is blocked and buffered by the circular baffle on the bottom surface of the upper capsule chuck, and again, part of the vulcanization medium changes direction, thereby reducing the force at the impact point where the vulcanization medium impacts the vulcanization capsule, improving the service life of the capsule, enhancing production efficiency, and reducing production costs.

[0018] The present utility model will be further described below with reference to the accompanying drawings.

[0019] All orientations involved in this specification are based on the orientation when a shock-proof vulcanization capsule chuck of the present utility model is working properly, without limiting its orientation during storage and transportation, only representing the relative positional relationship, not the absolute positional relationship.

[0020] As Figures 3 to 4 Collectively shown, a shock-proof vulcanization capsule chuck includes an upper chuck 1 and a lower chuck 2 arranged oppositely. A vulcanization capsule 3 is fixed between the upper chuck 1 and the lower chuck 2. A liquid inlet is provided on the lower chuck 2. In the prior art, the vulcanization medium enters the vulcanization capsule 3 from the liquid inlet, heats the vulcanization capsule 3, the vulcanization medium sprays onto the upper chuck 1 from the liquid inlet, and then refracts to both sides, impacting the side-axis impact point of the vulcanization capsule 3. After long-term impact, the position of the impact point becomes weak.

[0021] A plurality of buffer holes 4 are arranged at intervals on the bottom surface of the upper chuck 1. The bottom surface of the upper chuck 1 is an inclined surface 6 that slopes from the periphery to the center. The buffer holes 4 are located on the inclined surface 6. The buffer holes 4 are centered on the center of the upper chuck 1 and are arranged in a ring shape at intervals around the bottom surface of the upper chuck 1, and enclose a plurality of ring shapes with different diameters. The buffer holes 4 are blind holes, and the cross-sectional shape of the buffer holes 4 is an inverted trapezoidal structure with a narrow bottom and a wide top. When the vulcanization medium contacts the inclined surface 6, it enters the buffer holes 4. After being buffered in the buffer holes 4 with an inverted trapezoidal structure with a narrow bottom and a wide top, it spreads out around the upper chuck 1 at a relatively slow speed and with a relatively gentle impact force, reducing the refraction flow rate and impact force of the vulcanization medium on both sides of the vulcanization capsule 3.

[0022] Furthermore, a baffle 5 protruding towards the lower chuck 2 is arranged around the outside of the buffer holes 4. The cross-section of the baffle 5 is a crescent shape that bends towards the inside of the baffle 5. The vulcanization medium diffusing from the buffer holes 4 encounters the crescent-shaped baffle 5 that bends inwards, and the direction of part of the vulcanization medium is changed again, thereby reducing the force of the vulcanization medium impacting the impact point of the vulcanization capsule 3.

[0023] Furthermore, the baffle 5 and the upper chuck 1 are integrally formed, which can improve production efficiency and reduce production costs.

[0024] When vulcanizing a tire, the vulcanization medium enters the vulcanization capsule 3 from the liquid inlet and heats the vulcanization capsule 3. The vulcanization medium is sprayed from the liquid inlet onto the bottom surface of the upper chuck 1. By using the structure of the buffer holes 4, the refraction and splashing of the vulcanization medium are reduced, and the refraction flow rate and impact force of the vulcanization medium on the two-sided vulcanization capsules 3 are reduced. For the vulcanization medium refracting to both sides from the buffer holes 4, it is blocked and buffered by the circular baffle 5 on the bottom surface of the upper capsule chuck, and the direction of part of the vulcanization medium is changed again, thereby reducing the force of the vulcanization medium impacting the impact point of the vulcanization capsule 3, improving the service life of the capsule, improving production efficiency, and reducing production costs.

Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
