Specific embodiment

Refering to a kind of Bending Mould shown in Fig. 3-Fig. 6, being the present invention, comprising: upper mould 1 and lower mould 2 two large divisions, its master The thought is wanted to be: to treat that bending workpieces are placed in lower mould 2, upper mould 1 pushes to be made to treat bending workpieces bending and molding in lower mould 2.Below, Introduce the above construction of mould 1 and lower mould 2 and part annexation by concrete.

As shown in Figure 5 and Figure 6, upper mould 1 includes upper bolster 11,12, two groups of fixed plate, 13, two groups of longitudinal direction sides of horizontal master slider Slide block 14, drive block 15；

Wherein, this fixed plate 12 is arranged on upper bolster 11 center position, and two groups of horizontal master sliders 13 are respectively arranged at admittedly Before and after fixed board 12 both sides being slidably matched by inclined-plane with fixed plate 12 realize elastic, described horizontal master slider 13 Both sides are respectively provided with a right angle slide block 16 and are slidably matched, horizontal master slider 13 and right angle slide block flexible to realize left and right with its inclined-plane It is additionally provided with spring (not shown) with the state that remains retracted between 16；

Two groups of longitudinal side slides 14 are divided into the left and right sides of fixed plate 12 and longitudinal side slide 14 bottom is provided with and is fixed on The guide rail 17 of upper bolster 11, is shown in Figure 11；Drive block 15 and this longitudinal side slide 14 inclined-plane are slidably matched to control longitudinal side slide 14 move left and right along guide rail 17, see Figure 10, are additionally provided with spring (not shown) to keep between longitudinal side slide 14 and guide rail 17 Contraction state；

When above-mentioned 13, two groups of longitudinal side slides 14 of two groups of horizontal master sliders and right angle slide block 16 do not slide and fixed plate 12 Constitute the cuboid of a surfacing, and four lateral surface of this cuboid have the annular groove 10 of level connection；

As shown in figure 4, lower mould 2 includes die shoe 21 and the rectangle bending frame 22 being fixed on this die shoe 21, this rectangle Bending frame 22 treats bending workpieces for placement and rectangle bending frame 22 is obtained inner chamber and is adapted to described cuboid.Arrange on die shoe 21 There is the holding pad 25 within positioned at rectangle bending frame 22, treat the bottom surface of bending workpieces for extruding.

As the optimization further of the technical program, described die shoe 21 is provided with positioned at rectangle bending frame 22 outside four The outer guiding post 23 at angle, the outer bush 18 that upper bolster 11 is provided with outside cuboid and is coordinated with outer guiding post 23, upper mould 1 pushes When, just can vertically move under outer guiding post 23 with outer bush 18 cooperation and not offset it is ensured that depressing direction.

Further, described die shoe 21 is provided with the first limited post 24 positioned at rectangle bending frame 22 outside, upper mould The second limited post 19 that seat 11 is provided with outside cuboid and is coordinated with the first limited post 24, the first limited post 24 and second Limited post 19 cooperation prevents from pushing excessive or not enough.

Particularly, it is provided with upper padding plate 111 and the train wheel bridge 112 of stacking between described upper bolster 11 and cuboid, in order to Ensure that cuboid has enough height.

More specifically, before and after this fixed plate 12, both sides have slidably the first skewed slot 121 and the first stopper slot 122, see Fig. 7；As shown in figure 8, two groups of horizontal master sliders 13 all have the first inclined-plane 131 and the first limiting section 132, one of which is laterally led First inclined-plane 131 of slide block 13 and the first skewed slot 121 of fixed plate 12 front side coordinate, before the first limiting section 132 and fixed plate 12 First stopper slot 122 of side coordinates, the first skewed slot of the first inclined-plane 131 of another group of horizontal master slider 13 and fixed plate 12 rear side 121 cooperations, the first limiting section 132 and the first stopper slot 122 of fixed plate 12 rear side coordinate；This horizontal master slider 13 left and right sides There is the second skewed slot 133 and the second stopper slot 134, right angle slide block 16 has the second inclined-plane 161 and second limiting section of protrusion 162, see Fig. 9, the second inclined-plane 161 is coordinated with the second skewed slot 133, the second limiting section 162 is coordinated with the second stopper slot 134.

It is better understood upon the action relationships of this programme for the ease of technical staff, of the present invention Bending Mould is explained below Operation principle:

(1) first, as shown in Figure 1 is treated that bending workpieces are put in the rectangle bending frame 22 on die shoe 21, Ran Houshang Mould 1 down moves towards lower mould 2 under outer guiding post 23 with outer bush 18 cooperation；

(2) state when upper mould 1 pushes is the disengaged condition shown in Fig. 5, and this disengaged condition is two groups of horizontal master sliders 13 The both sides in front and back of opposing fixed plate 12 slide into minimum limit point under gravity, and before and after realization, both sides are shunk, in the same manner, described The laterally right angle slide block 16 also relatively transverse master slider 13 about two under self gravitation and spring effect of the both sides of master slider 13 Slideslip, shrinks about realization and reaches minimum point；Meanwhile, longitudinal side slide 14 is under the action of the spring so that two groups vertical To side slide 14 along guide rail 17 and the left and right sides of opposing fixed plate 12 is shunk；

(3) move downward with upper mould 1 and treat bending workpieces until touching, be bottom four right angle slide block 16 first with Treat bending workpieces contact squeeze so that the right angle slide block 16 outer Slideslip of relatively transverse master slider 13 about two, stretch out about realization, Until concordant with horizontal master slider 13；Slide into outside two before and after followed by horizontal master slider 13 opposing fixed plate 12 and fix Plate 12 is concordant, and before and after realization, both sides are upheld；Meanwhile, drive block 15 down move so that two groups of longitudinal side slides 14 along Left and right two outside of guide rail 17 opposing fixed plate 12 is upheld, and reaches blocking as shown in Figure 6, constitutes described cuboid； In the forming process of this cuboid, workpiece continuous bending under used by pressure, workpiece ragged edge curves right angle and stretches into described In annular groove 10, form bending and molding workpiece as shown in Figure 2；

(4) the bending and molding workpiece in previous step can't directly take out from the rectangle frame 22 of lower mould 2, needs to complete to take off Mould；Knockout course is up to put on mould 1 so that cuboid recovers the disengaged condition to (2nd) step, the upper mould under disengaged condition 1 depressed portion is smaller in size than the inward flange of bending and molding workpiece, just can separate upper mould 1 with bending and molding workpiece, then take out Bending and molding workpiece, thus complete whole bending link.

The foregoing is only the preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, as long as with The technical scheme that essentially identical means realize the object of the invention broadly falls within protection scope of the present invention.
