Background technology
For composite formed pressuring method, the general vacuum bag form that adopts is pressurizeed, and by vacuumizing, atmospheric pressure is acted on piece surface.For thicker composite formed of thickness, to meet the requirement of part forming to pressure only by atmospheric pressure, need the pressure requirements strengthened by other means needed for part forming, in this this embodiment, material thickness reaches 14mm, therefore needs a kind of afterburning mode completely newly, ensures to paste mould in part forming process, and can strut every layer of carbon cloth and make in order, prevent fold.
Summary of the invention
The invention provides a kind of pressue device of closed cross-section pipe box, it is characterized in that, comprise elastic expansion sleeve, briquetting combines, stressed skewback, pressurization skewback, screw rod, adhesive tape, afterburning nut, stop nut and handle, elastic expansion sleeve comprises circular cylinder and ring-type positioning sleeve, circular cylinder has and makes it have the flexible fork pockets of distending, the internal diameter of circular cylinder is reduced to centre gradually by end, the medial surface of briquetting combination adopts the cylinder concave surface coordinated with circular cylinder, the locating slot coordinated with ring-type positioning sleeve is had in the middle part of cylinder concave surface, the both sides end face of briquetting combination has the draw-in groove installing adhesive tape, stressed skewback is installed on circular cylinder side, the gradient of the internal diameter of the gradient circular cylinder of stressed skewback external diameter matches, the stressed skewback of pressurization skewback is installed on the opposite side of circular cylinder, the gradient of the internal diameter of the gradient circular cylinder of pressurization skewback external diameter matches, through hole is had in the middle part of stressed skewback and pressurization skewback, screw rod passes from through hole, afterburning nut coordinates with screw rod and drives stressed skewback and the skewback that pressurizes, stop nut is installed on screw rod, the position of close handle after being positioned at afterburning nut.
One embodiment of the present invention, ring-type positioning sleeve with protrusion guide part, and it is gradient to protrude the two side ends mask of guide part.Be combined with the space that briquetting combines with gradient outstanding guide part, can guide effect be played.
One embodiment of the present invention, briquetting combination is made up of the briquetting of more than three, and the quantity protruding guide part is identical with the quantity of briquetting.The quantity of briquetting, more than two pieces, under elastic expansion sleeve effect, can move to level and vertical both direction, squeezing bushing stressed more even.
The present invention can to the thicker composite of thickness in forming process, and closed cross-section pipe box region extrudes.
The present invention simple and effective guarantee can implement corresponding pressure to part, ensures forming quality, prevents laying distortion.

Detailed description of the invention
Below the present invention is described in further details.
Composition graphs 1 to Fig. 5, the present invention includes elastic expansion sleeve 1, briquetting combination 2, stressed skewback 3, pressurization skewback 4, screw rod 5, adhesive tape 6, afterburning nut 7, stop nut 8 and handle 9, described elastic expansion sleeve 1 comprises circular cylinder 1-1 and ring-type positioning sleeve 1-2, described circular cylinder 1-1 has and makes it have the flexible fork pockets 1-3 of distending, the internal diameter of described circular cylinder 1-1 is reduced to centre gradually by end, the medial surface of described briquetting combination 2 adopts the cylinder concave surface 2-1 coordinated with circular cylinder 1-1, the locating slot 2-2 coordinated with ring-type positioning sleeve 1-2 is had in the middle part of described cylinder concave surface 2-1, the both sides end face of briquetting combination 2 has the draw-in groove 2-3 installing described adhesive tape 6, described stressed skewback 3 is installed on circular cylinder 1-1 side, the gradient of the internal diameter of the gradient circular cylinder 1-1 of described stressed skewback 3 external diameter matches, the stressed skewback 3 of pressurization skewback 4 is installed on the opposite side of circular cylinder 1-1, the gradient of the internal diameter of the gradient circular cylinder 1-1 of pressurization skewback 4 external diameter matches, through hole 3-1 is had in the middle part of described stressed skewback 3 and pressurization skewback 4, described screw rod 5 passes from through hole 3-1, described afterburning nut 7 coordinates with described screw rod 5 and drives stressed skewback 3 and the skewback 4 that pressurizes, described stop nut 8 is installed on screw rod 5, the position of close handle 9 after being positioned at afterburning nut 7.By the effect of afterburning nut 7, screw rod 5 pulls stressed skewback 3 and pressurization skewback 4, act on elastic expansion sleeve 1 simultaneously, elastic expansion sleeve 1 struts briquetting combination 2, by the guiding on elastic expansion sleeve 1, can ensure that briquetting combination 2 effectively reclines, extrude corresponding region, adhesive tape 6 object is that fixing briquetting combination 2 makes it abut on elastic expansion sleeve 1, effectively can take back briquetting combination 2, make it abut on elastic expansion sleeve 1 during unloading pressure.The object of handle 9 is to prevent whole device from rotating.Stop nut 8 object is that preventing afterburning nut 7 from turning round causes pressure drop.
Part is after paving completes, put pressue device into inner cavity of component, profile is little compared with shape in part in a quiescent state, after being in place in briquetting combination 2, one holds handle 9, tighten afterburning nut 8 by spanner on the other hand, acted on by screw rod 5, stressed skewback 3 is moved to middle part with pressurization skewback 4, by the inclined-plane on two blocks and the ramp effect in elastic expansion sleeve 1, elastic expansion sleeve 1 can be strutted, and then strut briquetting combination 2, can pressurize to pressurization place.Pressure enough after, tighten stop nut 8, carry out pressurize.Loosen afterburning nut 7 and stop nut 8 after reaching requirement, pull handle 9, withdrawing device, briquetting combination 2 can restore to the original state under adhesive tape 6 acts on.
