Embodiment 1

[0018] Embodiment 1, with reference to Figure 1-Figure 4 , a mechanical setting device for vulcanization molding of automobile tires, including six pieces of small tiles and drum tiles 4 and six pieces of large tiles and drum tiles 10 that are arranged in the vulcanization The sliding link seat 13 and the fixed support 8 on the machine connection shaft sleeve 7, each small tile drum tile 4 is fixedly connected with its corresponding small tile drum block 3, and each small tile drum block 3 is connected through a pair of upper and lower parallel The set small tile long connecting rod 2 is hingedly connected with the sliding connecting rod seat 13, and in the middle of each upper small tile long connecting rod 2, a small tile short connecting rod 5 is hingedly connected, and the other end of the small tile short connecting rod 5 , is hingedly connected with the fixed support 8; each large tile drum tile 10 is fixedly connected with its corresponding large tile drum block 11, an...

Embodiment 2

[0019] Example 2, a mechanical shaping method for vulcanization molding of automobile tires, the method uses the mechanical shaping device described in Example 1 instead of a bladder or a water tire, and is used for shaping the inner wall of the tire blank during the vulcanization molding process of the tire. The mechanical rigid support of the sizing device replaces the flexible support of the bladder or water tire, and the radial expansion or contraction of the mechanical sizing device is used to replace the expansion or contraction of the bladder or water tire. The working process is: The mechanical setting device is connected with the lower pallet of the vulcanizing machine in advance, and it is in a shrinking state. Install the movable mold 14 on the vulcanizing machine. After completing the necessary preheating according to the normal pre-vulcanization preheating requirements, the vulcanizing machine starts to operate and the movable mold is opened. 14, load onto tire bas...

Abstract

The invention relates to a mechanical shaping method for automobile tire vulcanization molding. By using the rigid supporting effect of a mechanical shaping device to replace the flexible supporting effect of a capsule or a molding bag, insufficient tire dynamic balance accuracy caused by uneven wall thickness of the capsule or the molding bag is made up; by using the radial expansion or contraction of the mechanical shaping device to replace the expansion or contraction of the capsule or the molding bag, the goal of smoothly stripping off the tire is achieved; and by using steel materials to replace the rubber materials of the capsule or the molding bag, the goal of prolonging the service life is achieved. The mechanical shaping method comprises the working steps that: the mechanical shaping device is connected with the lower tray of a vulcanizing machine in advance and is kept in a contracted state; a segmented mold is installed on the vulcanizing machine and necessary preheating is conducted according to requirements on preheating before normal vulcanization; the vulcanizing machine starts to act, the detachable mold is opened and a green tire is installed; the vulcanizing machine acts, a slideable connecting rod seat on the mechanical shaping device is pushed, large shoes and small shoes are expanded to form an entire circle to shape the inner wall of the green tire; the vulcanizing machine continuously acts to drive the segmented mold to be closed and vulcanize; and the segmented mold is opened after vulcanization is finished and the tire is held and sent away by a manipulator.

Description

technical field [0001] The invention relates to a mechanical shaping method for automobile tire vulcanization molding. Background technique [0002] At present, the tire vulcanization process both at home and abroad uses bladders or water tires without exception. One of the important reasons is that the bladders or water tires can be inflated with air and adhere to the inner wall of the tire blank, pressing the tire blank to shape the tire. [0003] It is a traditional process to use bladders or water tires to shape and vulcanize tires. However, due to the harsh conditions of use of tire curing bladders, the temperature of the bladders is generally 180-200 degrees. The contact medium is mainly superheated water, superheated steam, compressed air or nitrogen. The stretch ratio of the capsule is very large, especially the oblique type capsule. Bladders or water tires are constantly expanding and contracting alternately in high-pressure and high-temperature environments, so t...
