Abstract

A tire post-inflation device comprises a support beam (1), a locking rod (2), a center rod (5), an upper tray (3) and a lower tray (4) coaxially disposed; the upper tray (3) is sleeved on the locking rod (2); the upper end of the upper tray (3) is fixedly connected to the support beam (1); the center rod (5) is provided with an engagement end (50) and a positioning end (51) thereon; the non-locking end of the locking rod (2) is provided with an axially threaded hole; the engagement end (50) is provided with external threads thereon; the locking rod (2) forms a screw transmission with the center rod (5) by utilizing the screwable connection between the threaded hole and the engagement end (50); the locking rod (2) axially reciprocates via the rotation and the screw transmission of the center rod (5). The device utilizes the up and down reciprocation of the locking rod (2) to adjust the rim width; the upper tray (3) is fixed on the support beam (1), is stationary in the whole working process of the post-inflation device, and is coaxial with the lower tray (4) with a high precision, such that the tire is unlikely to deform.

Description

technical field [0001] The invention relates to a tire post-inflation device, which is used for shaping and cooling the tire after vulcanization. Background technique [0002] At present, most of the post-inflation devices of domestic tire shaping vulcanizers use the position of the upper chuck or the lower chuck to determine the rim width that meets the specifications of the tire to be shaped. [0003] Such as figure 1 The tire rear inflation device shown includes a support beam 11, a locking bar 12, an upper tray 13 and a lower tray 14 arranged coaxially, the upper tray and the upper chuck together constitute an upper chuck assembly, and the lower tray and the upper chuck The lower chucks together constitute the lower chuck assembly, the locking rod 12 is fixed on the support beam 11, the upper tray 13 is sleeved on the locking rod 12; the lower tray 14 is sleeved on the inner disc seat 140 and The outer disc seat 141 on the top is formed, and the screw transmission is f...
