Guide rod 5 described in bending angle measurement mechanism of the present invention is arranged with two spacing preiection 5-1 for limiting slide position along the upper die and lower die center line of guide rod 5 length direction.The position of two spacing preiection 5-1 of the present invention is provided with relevant with the size of the pretightning force of extension spring 11, i.e. the pretightning force of extension spring 11 is large, and the distance between two spacing preiection 5-1 is large; The pretightning force of extension spring 11 is little, and the distance between two spacing preiection 5-1 is little.As shown in Figure 2.
The cantilever 6-3 of the left-half in bending angle measurement mechanism of the present invention in left-half and right half part and the angle feed-back element bracket 6 in right half part is oppositely arranged.In bending angle measurement mechanism left-half of the present invention and right half part, escapement 9 is oppositely arranged formation working face.Described working face and counterdie working face are positioned in same level.
In order to improve the globality of angle feed-back element bracket, rack body 6-2 of the present invention, cantilever 6-3 and bracket bosses 6-1 are one-body molded.
The course of work of bending angle measurement mechanism of the present invention:
As shown in Figure 1 and Figure 2, when bending is initial, workpiece 2 keeps flat and is placed on counterdie 3, bending starts rear patrix 1 and moves downward, workpiece 2 starts to deform under the effect of the pressure, escapement 9 rotates and fits in workpiece 2 outside surface, angle feed-back element bracket 6 is pushed open by both sides simultaneously, and movable head 7 is around the motion of angle feed-back element axle under the drive of connecting rod 8, and extension spring 11 is elongated.After bending completes, patrix 1 returns and moves upward, and workpiece 2 is taken away, and slide block 4 is returned to initial position under the effect of extension spring 11, and slide block 4 is spacing by the spacing preiection 5-1 on guide rod 5.Connecting rod 8 and movable head 7 move downward under gravity, finally spacing by the bracket bosses 6-1 on angle feed-back element bracket 6; Now escapement 9 also returns to original horizontal position under the drive of connecting rod 8, thus whole mechanism back is to initial position.
The angle that two movable heads 7 in the angle of two angle feed-back elements 10 in bending angle measurement mechanism of the present invention i.e. bending angle measurement mechanism of the present invention rotate.Do not mark out assuming that the value shown by two angle feed-back elements 10 in bending angle measurement mechanism of the present invention is respectively in α 1, α 2(figure), then workpiece 2 Integral bending angle is α=180 °-(α 1+ α 2).
Movable head 7 in bending angle measurement mechanism of the present invention, connecting rod 8 and escapement 9 form one group of linkage assembly.The present invention adopts this kind of linkage assembly effectively to overcome the impact that in prior art, steel wire plastic deformation brings.And in the present invention, after bending completes, slide block 4 is returned to initial position under the effect of extension spring 11, slide block 4 is spacing by the spacing preiection 5-1 on guide rod 5.Connecting rod 8 and movable head 7 move downward under gravity, finally spacing by the bracket bosses 6-1 on angle feed-back element bracket 6; Now escapement 9 also returns to original horizontal position under the drive of connecting rod 8, thus whole mechanism back is to initial position.This kind of mode does not need extra mechanism to be returned to original state to impel it.
Bending angle measurement mechanism of the present invention is when reality uses, and different according to the shape of counterdie, the left-half in bending angle measurement mechanism and the size of right half part can be different.When the shape of counterdie is " V " shape, the left-half in bending angle measurement mechanism is identical with the size of right half part, and left-half and right half part are symmetrical arranged about upper die and lower die center line.When the shape of counterdie is " W " shape, the left-half in bending angle measurement mechanism is not identical with the size of right half part, and namely the size of left-half is greater than the size of right half part, or the size of left-half is less than the size of right half part.Described here is only in size need not, the structure of the parts of its left-half and right half part and position relationship thereof are all identical.The length dimension of the different mainly connecting rod 8 of described size is different different from the size of the cantilever 6-3 on angle feed-back element bracket 6; In this case left-half and right half part are not symmetrically arranged about upper die and lower die center line.
Bender bending angle real time automatic measuring device of the present invention comprises patrix 1, counterdie, workpiece 2, pedestal 12 and the bending angle measurement mechanism of at least one; Counterdie and bending angle measurement mechanism are all fixed on pedestal 12, and bending angle measurement mechanism is between counterdie; .
Fig. 3 is the example of practical application of bender bending angle real time automatic measuring device of the present invention, as shown in Figure 3, bender bending angle real time automatic measuring device of the present invention comprise in patrix 1(Fig. 3 do not draw), do not draw in counterdie, workpiece 2(Fig. 3), pedestal 12 and two bending angle measurement mechanisms; Counterdie and two bending angle measurement mechanisms are all fixed on pedestal 12, and workpiece 2 is positioned on counterdie and bending angle measurement mechanism simultaneously.What the bender bending angle real time automatic measuring device shown in Fig. 3 was suitable for is the counterdie of " W " shape.Counterdie surface in this application example, in " W " shape, is provided with two bending angle measurement mechanisms in this application example.Fig. 3 is the schematic diagram that W pattern installs and measures device.This schematic diagram shows that this device is applicable to the slot mould of W pattern, and can be used for the wide mouth mould of W pattern simultaneously.
