Description

technical field

[0001] The invention belongs to the technical field of tire production machinery, and is equipment for the second step of forming a radial tire blank, in particular, it relates to a radially expanding bonding drum for forming a semi-steel wire radial tire blank. Background technique

[0002] At present, most of the laminating drums used in the two-stage molding of semi-steel wire radial tires are ten-watt or twelve-watt laminating drums. Since the laminating drums have fewer drum blocks, there are inconvenient adjustments, low production efficiency, and tire tires. Uneven blank forming quality, low precision, etc., and the slider is directly installed on the milling groove of the guide seat, and the slider drives the drum block to open or shrink by sliding in the milling groove. Due to the large sliding friction resistance, the production efficiency Low and short service life. Contents of the invention

[0003] The object of the present invention is to sol...
