Abstract
The utility model relates to a rubber hollow spring sphere which is composed of two hollow hemispheres which are glued by a joining material, wherein the hollow part of each hollow hemisphere is in a spherical cap shape, and the bottom surface of the hollow hemisphere is provided with a vulcanization joining material, and then a sphere body is formed by the hot press of a flat plate vulcanizer. The rubber hollow spring sphere of the utility model has the advantages of light weight and material saving.
Description
Technical field
The utility model relates to a kind of bounder, relates in particular to a kind of hollow rubber bounder.
Background technology
The history in existing more than 20 year of elastic rubber ball is that heat curing-type rubber BR Cis fourth synthetic rubber is made with raw material mainly, and the moulding of heat curing-type rubber kneading adds bridging agent, then by the extrusion modling of dull and stereotyped fluidisation machine, but all is solid, and weight is big, the waste raw material.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of hollow rubber bounder, and weight is little, saves material.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of hollow rubber bounder is provided, and this hollow rubber bounder is made up of by bond material is bonding the hemisphere of two hollows.
Further improvement in the technical proposal is: the hollow space of the hemisphere of hollow is a ball crown type.
Described grafting material is the sulfuration grafting material.
The beneficial effects of the utility model are: because the inside of hollow rubber bounder of the present utility model is hollow, but therefore economical with materials is more than 30%, and weight is little.
Description of drawings
Fig. 1 is the profile of the utility model hollow rubber bounder;
Fig. 2 is the profile of two hemisphere of the utility model hollow rubber bounder;
Fig. 3 and Fig. 4 are the master operation sketch of the utility model hollow rubber bounder manufacturing process.
The specific embodiment
Referring to Fig. 1 is the profile of the utility model hollow rubber bounder, and the material of spheroid is a heat curing-type rubber, and the thickness of spheroid is decided according to the size and the concrete condition of ball.Fig. 2 is the profile of hemisphere 1 of two hollows of the utility model hollow rubber bounder, its outer surface 2 and inner surface 3 all are the hemisphere hats, the hemisphere of two hollows is made by heat curing-type rubber, the moulding of heat curing-type rubber kneading adds bridging agent, be squeezed into dome-type by dull and stereotyped fluidisation machine then, the inside of dome-type is the cavity of ball crown type, and the hemisphere of two hollows is by vulcanizing grafting material through being hot pressed into spheroid.
Fig. 3 and Fig. 4 are the master operation sketch of the utility model hollow rubber bounder manufacturing process.The moulding of heat curing-type rubber kneading adds bridging agent, utilizes dome-type protruding, that die is squeezed into hollow then on dull and stereotyped fluidisation machine, hemisphere half-mature or well done between, Fig. 3 is the schematic diagram that die 4, punch 5 are squeezed into hemisphere.Hemisphere does not need from die 4 to take out, and the bottom surface of the hemisphere of two hollows is added the bottom surface alignment matched moulds of the hemisphere in 6, two dies 4 of sulfuration grafting material be hot pressed into spheroid through dull and stereotyped fluidisation machine then, as Fig. 4.Finished product is taken out in depanning, hollow projectile cartridge jump-ball finished product.
