The utility model belongs to the technical field of rubber processing, mainly for the design operation when agricultural plant protection machine tire child embryo uses the water tyre to vulcanize, improve production efficiency, reduce intensity of labour.
Background
The plant protection machine mainly works in the field ridges, field crops cannot be damaged during operation, and the requirements on large outer diameter of the tire and narrow cross section are met.
Vulcanization and shaping, namely changing the shaped cylindrical tire blank into a shape similar to the outline of the outer tire, and facilitating the installation of a water tire for vulcanization. A universal air setter is typically used. When in shaping, the water tyre is firstly placed on a hook above the shaping machine, and is pulled into the upper cylinder cavity by the action of compressed air in the air plug. The green tire is placed on a lower wheel disc of a workbench of a setting machine, an upper wheel disc of an air plug is put down, the tire bead part of the green tire is tightly pressed, and compressed air is filled inwards. The water tyre is inflated and then pressed downwards, the distance between the upper wheel disc and the lower wheel disc is not less than the width of the tyre crown, the tyre blank expands outwards under the action of air pressure, the outer diameter is increased, the section width is reduced, the water tyre falls down slowly and is filled into the tyre blank, the tyre blank gradually approaches to the shape of a flat circle similar to a tyre, the water tyre is fully relaxed, and the air in the tyre blank is discharged while compressed air is input into the water tyre, namely the water tyre is tightly attached to the tyre to achieve the purpose of shaping.
Because the tire of the plant protection machine has large outer diameter and narrow section, the tire body is thin, and the distance between two ring openings of the molded tire blank is narrow. When the upper wheel disc falls to the lowest position, the upper wheel disc still cannot contact the tire bead opening, so that the tire bead cannot be molded by a common air molding machine, and production stagnation is caused; in addition, the tire blank needs to be converted into different angles in the shaping process, so that the existing tire supporting machine has uneven stress on the inner wall of the tire blank.
