Problems solved by technology

[0003] The disadvantages of the above vulcanization methods are: 1. The heat of the vulcanization medium needs to be transferred to the green tire through the bladder, and the heat transfer has time delay and energy loss, resulting in long vulcanization time and low efficiency of the rubber air spring; It will be damaged after the service life, and a certain cost will be incurred; 3. Using the inner bag to shape the mold, the tire blank will expand unevenly, which will affect the service life and various performances of the product

Embodiment Construction

[0015] refer to figure 2 According to the bladder-free vulcanization production method of rubber air spring provided by the present invention, it specifically includes: canceling the bladder holder structure on the vulcanization mold 1, and directly loading the preformed rubber air spring tire blank 2 into the cavity of the vulcanization mold 1 , Use 0.1-1bar low-pressure air or nitrogen to shape the rubber air spring blank. After the mold is closed, fill in 6-15bar steam to provide heat for the rubber air spring blank, and then quickly fill in 18-35bar high-pressure nitrogen as the internal pressure medium Vulcanize.

[0016] As mentioned above, after the mold is closed, the interval between filling with steam and filling with nitrogen is 1min. An internal pressure medium circulation hole 4 is opened on the vulcanization mold 1 or the central rod 3 , and the air, nitrogen and steam are all filled into the vulcanization mold 1 through the internal pressure medium circulation...

Abstract

The invention discloses a rubber air spring capsule-free vulcanization production method, which comprises: removing a capsule holder structure from a vulcanization mold; directly filling a preformed rubber air spring blank into the molding cavity of the vulcanization mold; sizing the rubber air spring blank in the presence of air or nitrogen under a pressure of 0.1 to 1bar; closing the mold, and charging steam under a pressure of 6 to 15bar to provide heat for the rubber air spring blank; and quickly charging nitrogen serving as an internal pressure medium under a pressure of 18 to 35bar for vulcanization. In the invention, by applying a capsule-free vulcanization technical process, the method has the advantages of energy conservation, reduction in energy consumption, environmental friendliness, improvement on efficiency and the like and improves the uniformity and service life of products.

Description

Technical field: [0001] The invention relates to a vulcanization method used in the production of rubber air springs. No matter it is a model rubber air spring, a capsule rubber air spring or a rail vehicle rubber air spring, the method can be used for vulcanization production. Background technique: [0002] In the prior art, the vulcanized rubber air spring process uses a capsule as the vulcanization method of the inner bag, such as figure 1 As shown, in the vulcanization process, first install the bladder 1, fix the bladder 1 on the vulcanization mold 2, preheat the vulcanization mold 2 and the bladder 1 to the set temperature, and then put the green tire 3 on the bladder 1 After the mold is closed, it is started to be filled with internal pressure hot water or other media. The heat of the internal pressure hot water is transferred to the green tire through the capsule, and at the same time, the pressure of the internal pressure hot water is pressed against the green tire ...
