Abstract
The invention relates to a solid tire sulfuration technology for inner forming, outer heating and segment temperature control, which is in particular applicable to the sulfuration technology for large solid tire subjected to long-time sulfuration and belongs to the rubber tire manufacturing technology. The solid tire sulfuration technology is characterized by pressurizing and forming a tire blank in a sulfuration machine and realizing segment sulfuration by heating a mould on an additionally arranged sulfuration station platform. The invention greatly shortens the occupation time of the mould and improves the work efficiency of the sulfuration machine. Moreover, the invention has advantages of short occupation time of sulfuration machine, uniform sulfuration degree inside and outside the tire, large output of a single machine and the like.
Description
Technical field
The present invention relates to that typing, machine heat in a kind of machine outward, sectional temperature-controlled solid tyre sulfuration process, it is specially adapted to the sulfuration process of the large-scale solid tire of long-time sulfuration, belongs to the rubber tyre manufacturing technology.
Background technology
At present, the sulfuration process of general large-scale solid rubber tyre in the industry generally all is to adopt dull and stereotyped shaper vulcanizer to vulcanize, whole sulfidation all is to carry out in vulcanizer, the wall scroll tyre vulcanization time is longer, and single machine yield is little in the unit interval, and utilization rate of equipment and installations is low.Yet large-scale solid tyre vulcanizer price is comparatively expensive, must cause production cost to increase if only depend on increase sulfuration board to enlarge output.Simultaneously, the large-scale solid tire with traditional sulfuration process production generally all exists appearance over cure, inside to owe the defective workmanship of sulphur.Thereby design a kind of sulfuration process that can overcome the novel large solid tyre of above-mentioned defective and be very important.
Summary of the invention
The present invention proposes in a kind of machine at the deficiencies in the prior art that typing, machine are heated, sectional temperature-controlled solid tyre sulfuration process outward.
To achieve these goals, the technical solution adopted in the present invention:
One, the fetus of forming is put into straight and evenly the die cavity of process preheating.
Two, the mould in the step 1 is sent in the vulcanizer, fed steam to mould fetus is heated, simultaneously to the fetus extrusion forming.
Three, use locked mode bolt mold-locked up and down, disconnect steam, from vulcanizer, take out mould.
Four, the mould in the step 3 is placed on the sulfuration station platform, feeds steam to mould simultaneously, the steam regulation valve, according to first low temperature again the step time sharing segment of the last low temperature of high temperature tire is heated, finish until sulfuration.
Five, take out from mould with going out the tire of tire machine after molding sulfuration.
It is characterized in that: step 3 is set between step 2 and the step 5 promptly uses locked mode bolt mold-locked up and down, disconnect steam, the mould that taking-up mould and step 4 are about in the step 3 from vulcanizer is placed on the sulfuration station platform, feed steam to mould simultaneously, the steam regulation valve, according to first low temperature again the step time sharing segment of the last low temperature of high temperature tire is heated, finish until sulfuration.
The present invention has advantages such as the vulcanizer holding time is short, the inside and outside state of cure (vulcanization) of carcass is even, single machine yield is big.
The specific embodiment
For example the vulcanization process of the solid engineering tyre of 23.5-25/19.5 is as follows:
One, the empty mould of 23.5-25/19.5 is fed steam preheating to 130 ± 5 ℃ on the sulfuration station platform, and spray releasing agent uniformly for die cavity.The 23.5-25/19.5 fetus of forming is put in the mould, got togather mould.
Two, with crane mould is hung on the vulcanizer, feeding pressure to mould is that the steam of 0.25MPa heats, and opens the vulcanizer Hydraulic Station, to mould pressurization typing, crawl venting 5 times.
Three, pressurization was locked the locked mode bolt to mould after 30 minutes, opened vulcanizer.
Four, with crane mould is taken out from vulcanizer, be placed on the sulfuration station platform.Feed steam to mould, regulate pressure-reducing valve, steam pressure is controlled at 0.20 ± 0.01MPa, vulcanize after 6 hours, regulate pressure-reducing valve, steam pressure is controlled at 0.28 ± 0.01MPa, after vulcanizing 6 hours again, the adjusting pressure-reducing valve is controlled at 0.20 ± 0.01MPa with steam pressure, vulcanizes to disconnect steam after 8 hours.
Five, impose suitable pressure to upper and lower mould, unclamp the locked mode bolt, take out tire with going out the tire machine.
