Bladder vulcanized green tire shaping device and shaping method

Abstract

The invention relates to a bellows type sulfurized green tire setting device and method. The green tire setting device comprises a working base and support frames arranged on two sides of the working base relative to a sulfurized green tire side by side; the green tire setting device further comprises a jacking assembly, a first driving assembly, a first positioning assembly, a second driving assembly and a second positioning assembly which are sequentially arranged on the support frames and can slide along the support frames, the first driving assembly and the jacking assembly support the first positioning assembly through first guiding support rods, the first driving assembly and the first positioning assembly are connected through the first guiding support rods, and the second positioning assembly and the second driving assembly are connected through second guiding support rods. The bellows type sulfurized green tire setting device has the advantages as follows: height of the jacking assembly is adjusted according to size of a green tire, manufacturing time and production process for green tire setting are saved, and meanwhile, the device is simple in structure, high in universality and suitable for setting of large convolution bellows type bladder green tires with certain diameter range and different convolution bellow numbers.

Description

technical field [0001] The invention relates to an air spring blank shaping device and a shaping method for rail vehicles and engineering vibration reduction, in particular to a bladder type vulcanized green tire shaping device and a shaping method. Background technique [0002] With the development of science and technology, people put forward higher requirements for the stability, smoothness and safety of rail vehicle handling. At present, rail vehicles at home and abroad, including small cars, subways and urban rail trains, are mostly equipped with an air suspension damping system, which greatly improves the comfort and stability of the vehicle. The air spring is an important part of the automobile air suspension vibration reduction system. It uses the compression elasticity of the air to work, and has the functions of buffering, vibration reduction and load bearing. It is widely used, and at the same time, the capsule can also be applied to the vulcanized integral elbow...

Problems solved by technology

However, during the process from the molding size of the vulcanized tire blank of these bladders to the vulcanized bladder product, the external dimensions change greatly, which just increases the difficulty of vulcanization.

[0003] At present, two methods are mainly used for the shaping of the bladder embryo: one is to vulcanize after direct shaping on the horizontal mold on the flat vulcanizing machine. This method uses nitrogen vulcanization, which has higher requirements on the quality of the formed blastocyst. It is not easy to control, and the operation process is complicated. When the size of the blastocyst is large, the mold is too large, and the stroke requirements of the flat vulcanizing machine are also too large; the other is to vulcanize directly on the vertical vulcanizing mold on the vertical vulcanizing machine. The mold structure and operation process of this method are more complicated

The above two methods are directly vulcanized after being shaped on the vulcanization mold, but for large curved capsules, the corresponding vulcanization equipment and mold requirements are relatively high, and the operation process is complicated, which is likely to cause defects such as nesting and delamination, which will affect product quality. , so it is particularly important to develop a sizing device for the Daqu capsule vulcanized tire blank.
