Description of the embodiments

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present utility model is not limited to the specific embodiments disclosed below.

Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic can be included in at least one implementation of the utility model. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1 as a first embodiment of the present utility model, there is provided a compacting device for a bead filler of a semi-finished wheel, comprising an arc-shaped compacting platen 10 and a pressing device 20;

the arc compacting press plate 10 is used for extruding the ring opening of the semi-finished tyre 30;

the pressure applicator 20 is used to provide force transfer for compression of the arcuate compression platen 10.

Specifically, an arcuate compaction platen: according to the shape design of the ring opening of the semi-finished tire, the semi-finished tire can be better matched with the ring opening, and the compacting effect is better; when the compaction tool is used, the compaction tool is corresponding to a proper position according to the shape of the bead, the tool is squeezed by force to handshake, and the bead wrap which is pressed by the two pressing plates under the stress condition is in seamless fit with the bead opening of the semi-finished product wheel, so that the effect of compacting the bead wrap is achieved.

The pressing device 20 comprises a first pressing rod 21 and a second pressing rod 23;

the first pressure applying rod 21 and the second pressure applying rod 23 are rotatably connected in a crossed manner through a rotating shaft 25;

one end of the first pressing rod 21 and one end of the second pressing rod 23 are respectively provided with a first pressing handshake 22 and a second pressing handshake 24.

The arc compacting press plate 10 comprises an upper press plate 11 fixedly connected with the free end of a first pressing rod 21 and a lower press plate 12 fixedly connected with the free end of a second pressing rod 23.

The corresponding surfaces of the upper pressing plate 11 and the lower pressing plate 12 are respectively provided with an upper rubber pad 13 and a lower rubber pad 14.

The upper and

lower platens

11, 12 should match the bead shape of the green tire 30.
