Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of thermal efficiency height, curingprocess rate is fast, sulfide stress is big, production efficiency is high, product size is stable, qualification rate is high air spring vulcanizing device is provided.
According to the foregoing invention purpose, embodiment of the present utility model is:
A kind of air spring vulcanizing device, it comprises top board, urceolus and the lower platen that removably connects, be provided with concentric inner core in the urceolus, form the sulfuration chamber of ring seal between the inside and outside tube, the sulfuration that is provided with the curing bag of location, two ends and is enclosed within outside the inner core in described sulfuration chamber is roused, sulfureted air spring capsule is coated on outside the sulfuration drum, and on urceolus, be provided with air inlet and the exhaust sewage draining exit that sulfide stress is provided, it is characterized in that being wound with respectively in described urceolus and the inner core electrothermal chip by circuit control system control heating-up temperature; It is described that what sulfide stress was provided is high pressure air.
Be provided with the partiting thermal insulation plate between the bottom of described lower platen and air spring capsule, sulfuration drum and inner core.
The lower impressions that upper impression that the two ends of described curing bag are made of top board and urceolus respectively and urceolus and lower platen constitute is done radial and axial location.
Described electrothermal chip is heating wire or electrothermal tube.
Described sulfuration drum is provided with demoulding hole.
Compare with existing vulcanization plant, advantage of the present utility model is: 1. adopted the electrothermal chip heating mould, by circuit control system control heating-up temperature, so thermal efficiency height, curingprocess rate is fast, does not need boiler, and is pollution-free; 2. because sulfide stress is supplied with by high pressure air, and sulfide stress is big, and the operating temperature of curing bag is low in the sulfidation, can increase the service life, reduce product cost; 3. the product after vulcanizing can directly be put into water and cool off on mould, the time is short, the production efficiency height, and equipment is simple; 4. because formed product is cooled to the just demoulding of room temperature after sulfuration on the mould, therefore, the distortion of product framework material is little, dimensionally stable, qualification rate height.
