The utility model is characterized in that vapour and nitrogen are injected through separate pipes, the condensate water outlet pipe is led out from the lowermost position of the capsule through the central chassis and the master nitrogen recovery drainage pipe, a vapour spout pointing toward the lower tyre side is arranged on the side wall of the lower chuck in the vapour pipeline, a nitrogen spout pointing toward the upper tyre side is arranged on the sidewall of the central chassis to form the agitation of the nitrogen to the vapour and generate circumfluence, so that the medium in the capsule is mixed evenly and becomes high temperature and high pressure medium and facilitates vulcanization to improve the tyre quality.

Description

Steam nitrogen is pouring-in R1B type tire forming vulcanizer central authority along separate routes

The utility model relates to the central authority of tire forming vulcanizer, and what be specially adapted to a kind of R1B type tire forming vulcanizer fills nitrogen high temp sulphur center mechanism.

When existing R1B type tire forming vulcanizer was used to fill the nitrogen high temp sulfuration, its central authority was the superheated water open type, and nitrogen and steam enter capsule by same path, spray near the tire upper sidewall.Steam sprays into the tire upper sidewall, the temperature rise of tire upper sidewall is accelerated, and because steam proportion is littler than nitrogen, in sulfidation, steam can accumulate in capsule top, cause the upper sidewall temperature higher, then accumulate the tire lower sidewall certain condensed water, cause temperature rise slower, formed certain temperature difference in capsule thus, its temperature difference is 8 ℃-12 ℃, because cure time calculates with the capsule bottom temp, therefore, device for prolonging cure time, to making limit, tire upper sidewall be easy to generate over cure and influence tire quality.

Goal of the invention of the present utility model is: overcome the said structure shortcoming that existing R1B type tire forming vulcanizer central authority exists, for the user provides a kind of uniform high-temperature high-pressure medium of guaranteeing to form in capsule, improve the tyre vulcanization quality effectively, and have simple in structure, fitting operation is easy to maintenance, manufacturing cost is lower, steam nitrogen pouring-in R1B type tire forming vulcanizer central authority along separate routes.

Goal of the invention of the present utility model realizes by implementing following technical proposals: steam nitrogen is pouring-in R1B type tire forming vulcanizer central authority (hereinafter to be referred as this central authority) along separate routes, by being contained in vulcanizer mould (9) centre, pressurized nitrogen on capsule (7) the lower central chassis (1), reclaiming nitrogen and condensed water discharge pipe road forms, it is characterized in that: with the existing same pipeline open type that is contained on the central chassis, steam is different with the vulcanizer central authority that pressurized nitrogen enters capsule, steam independent of each other injects center culvert to this central authority on the central chassis by being contained in, the pressurized nitrogen filling line, and front end extend into the capsule bottommost, pass central chassis, stretching into the condensed water drain hose that runs through in the nitrogen recycling master comb forms; Wherein, steam injects center culvert, by passing central chassis, extend into the steam pipe at capsule top center position, dress is inserted in the steam pipe termination, its intracavity sidewall has the newel of steam through hole, be fixed on the shrouding on the tube wall of steam pipe termination, be sleeved on the newel and and form one with shrouding, on the sidewall along the equidistant spout that has uperize of horizontal circle week, form steam channel between bottom surface and shrouding face, and with newel on the following chuck that links of steam through hole, suit is fixed on the cushion block on the newel termination, be contained on the cushion block and and cooperate the last chuck of clamping capsule, and will go up the nut that chuck is fixed on the cushion block and form with following chuck; The pressurized nitrogen pipeline, inject spout by the equidistant nitrogen of offering on the pre-face circumference of central chassis, the channel of nitrogen that in the central chassis sidewall, has that connects with these spouts, and the pressurized nitrogen ascending pipe that is contained under this chassis that links of passage is formed therewith.Its additional technical feature is: 1. in this mechanism, be sleeved on the following chuck that forms one on the newel with shrouding, along equidistant spout that has uperize of horizontal circle week, the duct direction of these spouts is for pointing to the pointing direction in zone, lower sidewall from level on its sidewall.2. on central chassis end face circumference, equidistant pressurized nitrogen that has injects spout, and its spout duct direction is for pointing to the direction in zone, upper sidewall.3. in the central chassis of capsule bottom, be equipped with around the thermometric thermal resistance of the measurement capsule actual temperature of trying to get to the heart of a matter, this resistance remainder connects at the top again and passes central chassis, and in the whole armour tubing that passes in the pressurized nitrogen ascending pipe.

Advantage of the present utility model is: because in this central authority, pressurized nitrogen injects with vapours and is injected to the separate pipe lines structure, be convenient to heat and effective control of pressurizeing, help forming in the capsule uniform dielectric of HTHP; Because under capsule on the chuck sidewall, offered special-purpose vapor injection port along horizontal circumference is equidistant, adjust jet duct direction, can change the flow direction of high-temperature steam in capsule, under the sensing of these jets, steam with circulating current system along horizontal direction or spray into the zone, lower sidewall of capsule middle part, middle and lower part along horizontal downward direction, and pressurized nitrogen sprays to the zone, upper sidewall of tire intermittently from the oblique spout on the central chassis sidewall, formed steam ground has been stirred, caused the high-temperature high-pressure medium that formation mixes in capsule; Accumulate in the condensed water in the capsule lower curtate zone, extend into herein, pass central chassis, stretch into the scupper hose that penetrates in the nitrogen recycling master comb and the steam trap of tail end thereof by front end, condensed water is discharged outside the capsule, guaranteed the thermally equivalent of tire lower sidewall, reduce the internal difference in temperature of capsule, thereby improved the quality of tyre vulcanization widely.
