Conjunction, stress skewback, pressurization skewback, screw rod, adhesive tape, afterburning nut, stop nut and handle, elastic expansion sleeve include circular cylinder and
Ring-type positioning sleeve, circular cylinder has the fork pockets making it have distending elasticity, the internal diameter of circular cylinder from end to centre by
Tapered little, using the cylinder concave surface with circular cylinder cooperation, it is fixed with ring-type to have in the middle part of cylinder concave surface for the medial surface of briquetting combination
The locating slot of position set cooperation, the both sides end face of briquetting combination has the draw-in groove installing adhesive tape, stress skewback is installed on annular canister
Body side, the gradient of the internal diameter of gradient circular cylinder of stress skewback external diameter matches, and pressurization skewback stress skewback is installed on ring
The opposite side of shape cylinder, the gradient of the internal diameter of gradient circular cylinder of pressurization skewback external diameter matches, and stress skewback and pressurization are tiltedly
Through hole is had, screw rod passes through from through hole, afterburning nut and screw rod cooperation drive stress skewback and pressurization skewback, spacing in the middle part of block
Nut is installed on screw rod, near the position of handle after afterburning nut.
One embodiment of the present invention, the protrusion guide part that ring-type positioning sleeve carries, and protrude the two side ends of guide part
Mask is gradient.Combine with the space that gradient prominent guide part is combined with briquetting, guide effect can be played.
One embodiment of the present invention, briquetting combination be made up of the briquetting of more than three, protrude guide part quantity with
The quantity of briquetting is identical.The quantity of briquetting is more than two pieces, can move to horizontally and vertically both direction under elastic expansion sleeve effect
Dynamic, being more uniformly stressed of squeezing bushing.
The present invention can be thicker to thickness composite in forming process, closed cross-section pipe box region is extruded.
The present invention can simple and effective ensure to implement corresponding pressure to part it is ensured that forming quality, prevents laying from turning round
Bent.

Specific embodiment
Below the present invention is described in further details.
In conjunction with Fig. 1 to Fig. 5, the present invention include elastic expansion sleeve 1, briquetting combination 2, stress 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 includes circular cylinder 1-1 and ring-type positioning sleeve 1-2,
The fork pockets 1-3 making it have distending elasticity is had on described circular cylinder 1-1, the internal diameter of described circular cylinder 1-1 from end to
Centre is gradually reduced, and the medial surface of described briquetting combination 2 is using cylinder concave surface 2-1 with circular cylinder 1-1 cooperation, described cylinder
Have the locating slot 2-2 with ring-type positioning sleeve 1-2 cooperation in the middle part of concave surface 2-1, the both sides end face of briquetting combination 2 has installation institute
State the draw-in groove 2-3 of adhesive tape 6, described stress skewback 3 is installed on circular cylinder 1-1 side, the gradient ring of described stress skewback 3 external diameter
The gradient of the internal diameter of shape cylinder 1-1 matches, and pressurization skewback 4 is installed on the opposite side of circular cylinder 1-1, and pressurize skewback 4 external diameter
The gradient of the internal diameter of gradient circular cylinder 1-1 match, have through hole 3-1 in the middle part of described stress skewback 3 and pressurization skewback 4,
Described screw rod 5 passes through from through hole 3-1, and described reinforcing nut 7 drives stress skewback 3 and pressurization skewback with described screw rod 5 cooperation
4, described stop nut 8 is installed on screw rod 5, near the position of handle 9 after afterburning nut 7.Work by afterburning nut 7
With screw rod 5 pulls stress skewback 3 and pressurization skewback 4, acts simultaneously on elastic expansion sleeve 1, and elastic expansion sleeve 1 struts briquetting combination
2, by the guiding on elastic expansion sleeve 1, ensure that briquetting combination 2 effectively reclines, extrude corresponding region, adhesive tape 6 purpose
