Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of flywheel energy storage shell body processing assembly, comprise the shell body 1 of tubular, extrusion head 2 and lower extrusion head 3 is provided with in described shell body 1, described upper extrusion head 2 and lower extrusion head 3 coordinate extruding vertically, described upper extrusion head 2, multiple rubber pneumatic bag 4 is filled with between lower extrusion head 3 and shell body 1 inwall, described multiple rubber pneumatic bag 4 is bound by by upper extrusion head 2, in the cavity that lower extrusion head 3 and shell body 1 inwall are formed, contact with shell body 1 inner wall pressure under the squeezing action of upper extrusion head 2 with lower extrusion head 3 with the rubber pneumatic bag 4 of shell body 1 contact internal walls.
Space is provided with between described upper extrusion head 2 outward flange and shell body 1 inwall.
Space is provided with between described lower extrusion head 3 outward flange and shell body 1 inwall.
Described upper extrusion head 2 lower surface is the upper extruding conical surface 5 of middle part to lower convexity.
Described lower extrusion head 3 upper surface is the lower extruding conical surface 6 that middle part raises up.
Shell body 1 outside that inside is provided with rubber pneumatic bag 4 is provided with processing component 7.
Described rubber pneumatic bag 4 is made up of courage 9 in black rubber inner bag 8, General Purpose Rubber and elastic emulsion skin 10, and described rubber pneumatic bag 4 is provided with air valve 11, and described air valve 11 collar extension is absorbed in elastic emulsion skin 10.Outer 10 thickness of described elastic emulsion are 0.5-1cm, and preferred 1cm is convenient to rubber pneumatic bag 4 like this and is formed larger contact area with shell body 1 inwall.
Also be provided with nylon between courage 9 in described black rubber inner bag 8 and General Purpose Rubber and twine silk layer 12.
Described rubber pneumatic bag 4 external diameter is 3 ~ 10cm, and described void size is 10% ~ 30% of rubber pneumatic bag 4 external diameter.
Described shell body 1 inwall is provided with smooth polytetrafluoroethylene floor.
In the process used, first lower extrusion head 3 is made to be arranged on shell body 1 inner, then rubber pneumatic bag 4 is filled between lower extrusion head 3 and shell body 1 inwall, then upper extrusion head 2 is coordinated with shell body 1, in control, extrusion head 2 and lower extrusion head 3 run in opposite directions, the upper extruding conical surface 5 and the lower extruding conical surface 6 coordinate and are extruded by multiple rubber pneumatic bag 4, contact with the inner mineralization pressure of shell body 1 with the rubber pneumatic bag 4 of shell body 1 contact internal walls, support force is formed radially to shell body 1, Milling Process can be carried out by processing component 7 in shell body 1 outside that inside is provided with rubber pneumatic bag 4, because there is the existence of support force shell body 1 inside, so power when processing component 7 pairs of shell bodies 1 of Milling Process act on causes distortion hardly, axially running the Support Position that can change shell body 1 radial direction by controlling above extrusion head 2 and lower extrusion head 3 simultaneously, coordinating outside Working position,
In the machining needing punching, even if in multiple rubber pneumatic bag 4 bores broken by drill bit, other air bag meeting supplementary support, can not have a huge impact the radial crushing strength of shell body 1.
Axially run in the operation changing radial support position at upper extrusion head 2 and lower extrusion head 3, the inconvenience of inner support pressure can be kept, require that shell body 1 inwall is comparatively smooth like this, smooth polytetrafluoroethylene floor can be provided with on inwall; Also above extrusion head 2 and lower extrusion head 3 differential can run simultaneously, after decompression, increase again after moving into place, realize mobile object equally.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
