Air spring vulcanized green tire shaping device and shaping method

Abstract

The invention relates to a shaping device and a shaping method for a tyre germ of an automobile air spring, in particular to a shaping device and a shaping method for a tyre germ of a sleeved air spring. The shaping device mainly comprises a working platform, an action head, a shaping device, a reset device and a driving device, wherein when the shaping device is in a free condition, a shaping cylinder is in a tightened condition; when the shaping device is in a working condition, the action head moves downwards under the action of a cylinder pull rod until the shaping cylinder reaches to a pre-arranged taper of the tyre germ. The shaping device has the advantages that the shaping cylinder is a sectioning shaping cylinder; position of an angle limiting snap ring on a cylinder collecting ring is adjusted according to the taper of a tyre germ to be shaped, so as to reduce manufacturing time and manufacturing process of tyre germ shaping, and improve sulfuration precision of tyre germ mounting; the shaping method is simple and convenient, and improves shaping sulfuration quality of a product.

Description

technical field [0001] The invention relates to a tire blank shaping device and a shaping method for an air spring for a vehicle, in particular to a tire blank shaping device and a shaping method for a sleeve-type air spring. Background technique [0002] With the development of science and technology, higher requirements are put forward for the handling stability, ride comfort and safety of automobiles. At present, most high-end MPVs, SUVs and small commercial vehicles at home and abroad are equipped with air suspension damping systems, which greatly improve the comfort and stability of the vehicles. The air spring assemblies of these air suspension systems are mainly composed of sleeve-type capsule assemblies and damping The capsule is composed of a vibrator, and the capsule is divided into a straight type and a cone type. The manufacturing process of the straight type capsule is relatively simple, and the cone type capsule has a large port and a small port, that is, there...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly two manufacturing methods for the cone-shaped bladder of the sleeve-type air spring: one is to pre-form the cone-shaped tire blank through the molding head in the molding process, and then vulcanize with the cone-shaped diaphragm or hard core. Method Because the time interval between the molding process and the vulcanization process is long, it is easy to cause the natural shrinkage of the tire blank, and the taper becomes smaller, which affects the efficiency and product quality of the blank vulcanization; the other is to form a straight tube tire through the molding head in the molding process. Then in the vulcanization process, vulcanize with the help of a straight diaphragm. This method is prone to reduce the service life of the diaphragm due to the large deformation of the diaphragm and the embryo during the vulcanization process, and the embryo is easy to nest during the vulcanization process. The length of the curing bladder is not easy to control, etc., which seriously affects the quality of the bladder
