Right-hand component comprises and is installed in the supporting traverses 41 that symmetry before and after the seat two of 21 right-hand members is stretched on the top, one end of each supporting traverse 41 and top are stretched seat 21 and are hinged, the other end of each supporting traverse 41 is fixed with stretching cylinder 42, be fixed with stretching movable joint 44 on the piston rod of this stretching cylinder 42, the both ends of stretching movable joint 44 are connected with rocker clamping plate 46 respectively by pin, two rocker clamping plate 46 link together by pin and form a rocker 4, stretching movable joint 44 is hinged with rocker 4 middle parts, former and later two rockers 4 link together by pin, the bottom of each rocker 4 all is hinged on the frame 1, stretching movable joint 44 can promote rocker 4 with frame 1 pin joint be that the swing in the perpendicular is done in the center of circle; A stretching bar 5 is arranged respectively on two arc-shaped guide plates 28, can slide on arc-shaped guide plate 28 in one end of stretching bar 5, the top of the other end of stretching bar 5 and rocker 4 is hinged, also be provided with the stretching chuck 54 that is used for clamping work pieces 6 between two stretching bars 5, this stretching chuck 54 can move in perpendicular with stretching bar 5;

Left-hand component also is provided with the parts identical with right-hand component, these parts comprise supporting traverse, stretching cylinder, stretching movable joint, rocker, stretching bar, stretching chuck, their structure is identical with the corresponding component of right-hand component with annexation, and each parts of left-hand component and each corresponding component of right-hand component are symmetrical centre symmetry one by one with the core.

Be fixed with foot rest 12 on the frame 1, be useful on the clamping plate 13, the clamp bar 14 that connect foot rest 12 on the foot rest 12, have under the clamping plate pivot pin of strap 13 and foot rest 12 17 on the clamping plate 13, in the clamping plate pivot pin 49, have under the clamping plate pivot pin of strap 13 and foot rest 12 17 on the clamping plate axle clamp plate 13, in the clamping plate pivot pin 49, on the clamping plate pivot pin 48, be fixed with link plate 15 and supporting plate 16 on the clamping plate 13, the fixedly base plate pin 18 of supporting plate 16 is arranged on the supporting plate 16, and foot rest 12, clamping plate 13, link plate 15, supporting plate 16 are installed in the jacking bending drawframe center.

As shown in Figure 5, the top is stretched to post on the seat 21 to push up and is stretched scale 26 with the record top amount of stretching, and limits stroke by stroke collision block 27, and arc-shaped guide plate 28 is installed in the top and stretches on the seat 21.

Clamping plate 13, clamp bar 14, link plate 15 are put into melt pit 7 with supporting plate 16, and frame 1 is fixed on the ground by horizontal direction.

Part to be formed for example is a metallic plate, this piece metallic plate is clipped within two stretching chucks 54, two stretching chuck 54 crampings, make the jaw chucking workpiece 6 in the stretching chuck 54, cylinder 25 pressurizations are stretched on the top simultaneously, mould 3 is upwards slided, workpiece pressing 6, workpiece 6 moves up under the promotion of mould 3, because of be stretched chuck 54 of workpiece 6 two ends clamps, make workpiece 6 stretchings and exceed its elastic limit, moulding distortion on drawing and forming mould 3 forms arc, stretching bar 5 is stretched under the drive of the arc-shaped guide plate 28 on the seat 21 on the top, in horizontal plane, do the swing of certain angle, and an end of stretching bar 5 slides on arc-shaped guide plate 28, make stretching bar 5 constantly tangent with the cambered surface of mould 3.

Under the promotion of stretching cylinder 42, rocker 4 is done the wobbling action in the vertical plane, cause is hinged with frame 1, so can be that swing in vertical plane in the center of circle with the pin joint, because of rocker 4 also is an articulated structure with stretching bar 5, so in rocker 4 swings, pulling stretching bar 5 makes it at vertical in-plane moving, so stretching bar 5 when processing work 6, is subjected to the promotion that arc-shaped guide plate 28 makes progress on the one hand, be subjected to the pulling of rocker 4 on the one hand to both sides, stretching bar 5 can with the hinged point of rocker 4 be the center of circle, in vertical plane, swing, to keep tangent with the cambered surface of mould 3, constantly workpiece 6 is under the extended state again, produces plastic deformation.

In the said process, moving of total both direction, be respectively to push up longitudinally and stretch cylinder 25 and horizontal stretching cylinder 42, the top is stretched cylinder 25 1 ends and is fixed in the melt pit by supporting plate 16, directly be fixed on the ground pitted surface, one end promotes the top and stretches seat 21, and it is slided in guide rail 22, promotes mould 3 mounted thereto.Stretching cylinder 42 is hinged on the seat that stretches by supporting traverse 41, lifting with the seat that stretches is that the swing in the vertical plane is done in the center of circle with the pin joint with the seat that stretches, stretching cylinder 42 other ends promote rocker 4 and make rocker 4 swings, and further spur stretching bar 5 and move, stretching bar 5 one ends can be stretched on the arc-shaped guide plate 28 of seat on 21 and slide being fixed on the top, make this end with moving the tangent of maintenance always and mould 3 cambered surfaces on the mould 3, one end is done the action that stretches with the swing of rocker 4, drive stretching chuck 54 stretched parts, swing about stretching chuck 54 can be done, make the jaw of stretching chuck 54 face the tangential direction of mould 3, prevent the distortion of workpiece.
