Problems solved by technology
In sporadic use such as on-site maintenance, it is unrealistic and difficult to prepare all O-shaped rubber seals with nominal diameters for use. At the same time, some O-shaped rubber seals with nominal diameters are not commonly used. If the inventory is not used for a long time, it will cause aging failure and unnecessary waste
However, if the O-ring rubber seals of various specifications and sizes are not prepared, the maintenance progress will often be affected due to the lack of O-ring rubber seals of corresponding specifications.

The invention discloses an O-shaped sealing ring making tool which consists of a lower cover and an upper cover; the upper surface of the lower cover is provided with at least one lower continuous manger, the cross section of which is in a semicircular shape, while the lower surface of the upper cover is correspondingly provided with an upper continuous manger, the diameter of which is equal to that of the lower continuous manger; after the upper cover and the lower cover are folded and closed, the upper continuous manger and the lower continuous manger form a hole, the cross-sectional diameter of which is less than or equal to the cross-sectional diameter of the O-shaped sealing ring to be processed; the O-shaped sealing ring making tool can be used for making the O-shaped rubber sealingrings with any nominal diameter at any time in accordance with the requirements of in situ maintenance or occasional use, thus shortening maintenance period and saving maintenance cost; moreover, theO-shaped sealing ring making tool has simple structure and is convenient for being used and carried.
Description
Technical field [0001] The present invention involves a sealing ring making mold, which specializes in a type of O -dense sealing tool. Background technique [0002] O -shaped rubber sealing rings are widely used in various fields due to low cost, convenient use, and strong adaptability.Under normal circumstances, O -shaped rubber sealing rings are all finished products produced in accordance with relevant standards. In the size series of national standard O -rubber sealing rings, the section diameter of the O -shaped rubber seal ring is basically basically available in diameter. 1.9mm, 2.4mm, 3.1mm, 3.5mm, 5.7mm, 8.6mm six specifications, while the nominal inner diameter or outer diameter is as many as 160 specifications.In sporadic use such as on -site maintenance, it is unrealistic and difficult to use all the named O -rubber sealing circles of all nominal diameter specifications. At the same time, some of the O -rubber sealing rings of some publicly called diameter are ...
