The vulcanizing mold is provided with a vulcanizing mold, a temperature measuring hole is formed in the position of an upper steel ring of the vulcanizing mold, a capsule is clamped between the upper steel ring of the vulcanizing mold and an upper capsule chuck, the front end of a thermocouple wire penetrates through the temperature measuring hole to be connected with a thermocouple, the front end of the thermocouple is in contact with the surface of the capsule, and the tail end of the thermocouple wire is connected with a temperature measuring instrument. The utility model discloses simple structure can strictly monitor the type of the used capsule of tire vulcanizer under the condition of not destroying the capsule to the emergence of the tire defect of leading to because of the capsule type is with wrong has been avoided.
Description
Technical Field
The utility model relates to a tire production facility field says in detail to a nondestructive test tire vulcanizes device with capsule type.
Background
It is known that various unvulcanized tires require a certain temperature, pressure, and time within a vulcanizer to complete complex chemical reactions. The heat required for vulcanizing the tire is provided to the tire by the internal temperature and the external temperature. The external temperature is provided by an upper hot plate, a lower hot plate and a die sleeve of the tire vulcanizer; the internal temperature is transmitted to the tire by high temperature steam through the bladder.
The process of vulcanizing tyre is that the tyre blank is placed in a vulcanizing mould, the inside of the tyre blank is filled with a vulcanizing capsule, and the capsule is filled with a vulcanizing medium (high-temperature steam). The vulcanizing medium provides the temperature and pressure required by vulcanization to the capsule, and the capsule transmits the temperature and pressure to the tire blank to complete the tire vulcanization process after a certain period of time.
At present, temperature monitoring systems of internal temperature are all arranged on a steam pipeline, if the type of the capsule is a common type capsule instead of a high-heat-conductivity type capsule, namely the heat conductivity coefficient of the capsule does not reach the standard, although the temperature on the steam pipeline reaches a set standard temperature value, the capsule cannot provide enough heat required by tire vulcanization, and the vulcanized tire is likely to have ill symptoms such as unripe (sponge) and the like.
When the type of the capsule is detected by tire enterprises at present, a sample is cut from the capsule to be detected in a factory and sent to an internal quality detection department, and the detection department measures the heat conductivity of the capsule by using a special heat conductivity coefficient instrument to judge the type of the capsule.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a device of nondestructive test tire vulcanization with capsule type adopts the thermocouple wire to come the temperature of the used capsule of nondestructive test to judge the capsule type.
The utility model provides a technical scheme that its technical problem adopted is: a device for nondestructively detecting the type of a bladder for tire vulcanization is provided with a vulcanization mold and is characterized in that a temperature measuring hole is formed in the position of an upper steel ring of the vulcanization mold, the bladder is clamped between the upper steel ring of the vulcanization mold and an upper chuck of the bladder, the front end of a thermocouple wire penetrates through the temperature measuring hole to be connected with a thermocouple, the front end of the thermocouple wire is in contact with the surface of the bladder, and the tail end of the thermocouple wire is connected with a thermodetector.
The beneficial effects of the utility model are that, simple structure can strictly monitor the type of the used capsule of tire vulcanizer under the condition of not destroying the capsule to the emergence of the tire defect of leading to because of the capsule type is with wrong has been avoided.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In figure 1. capsule upper chuck; 2. a capsule; 3. steel rings are arranged on the vulcanizing mould; 4. a tire; 5. a temperature measuring hole; 6. and (4) thermocouple wires.
Detailed Description
In fig. 1, the utility model discloses be equipped with the vulcanization mould utensil, 3 processing temperature measurement holes 5 of steel ring on the vulcanization mould utensil of vulcanization mould utensil, the capsule 2 has clamped on the vulcanization mould utensil between steel ring 3 and the capsule chuck 1, and 6 front ends of thermocouple wire pass temperature measurement holes 5 and link to each other with the thermocouple, thermocouple front end and 2 surface contact of capsule, 6 terminal and the thermoscope hookups of thermocouple wire.
In the die assembly and vulcanization process of the vulcanizing machine, the capsule upper chuck 1, the capsule 2, the vulcanizing mold upper steel ring 3 and the tire 4 are combined into a closed cavity, the front end of the thermocouple is in contact with the surface of the capsule 2, the tail end of the thermocouple lead 6 can be connected into a host computer of the vulcanizing machine or can be independently connected onto a temperature measuring instrument, and in the whole vulcanization process, the thermocouple lead 6 acquires the temperature value of the surface of the capsule 2 in real time.
