Specific embodiment
As illustrated in figs. 1-16, including fuselage 1, be slidably connected the present invention sliding block 2 on the fuselage 1 and a pair of for driving cunning
The driving mechanism of the reciprocal elevating movement of block, a pair of driving mechanism are symmetrically set to the two sides of sliding block 2；
The driving mechanism includes motor 31, screw rod 32, fixing seat 33, nut seat 34 and a pair of links component, the connection rod set
Part includes upper connecting rod 351, vertical connecting rod 352 and lower link 353, and the vertical connecting rod 352 is vertically arranged, the upper connecting rod 351
It is isometric with lower link 353 and along vertical 352 center symmetric setting of connecting rod, the top of the upper connecting rod 351 and fuselage 1 it is hinged and
Bottom end and the top of vertical connecting rod 352 are hinged, and the bottom end of the lower link 353 passes through the lifting hinged block being fixedly connected on sliding block
Hinged and top and vertical connecting rod 352 the lower hinge with sliding block 2；
The motor 31 is fixedly connected on side and the holding level of one of them vertical connecting rod 352, the screw rod by support
32 wear two vertical connecting rods 352 and holding level, and the motor 31 and screw rod 32 pass through transmission belt and link, the fixing seat 33
The two sides of screw rod 32 are symmetrically socketed in nut seat 34 and fixing seat 33 is in where 31 position of motor and nut seat 34
Between position；Wherein, the screw rod 32, which can and only can fix relatively seat 33 and make rotating motion, (can be achieved the structure of this manner of execution
Have very much, position limiting convex ring is such as set in fixing seat while opening up limited step on screw rod；Or in screw rod and fixing seat
Between bearing is set so that bearing outer wall and fixing seat are interference fitted, and bearing inner wall and screw rod are interference fitted etc.),
The screw rod 32 is connected through a screw thread with nut seat 34；
The fixing seat 33, nut seat 34 are connected with two vertical connecting rods 352 respectively by vertical holding mechanism, and a pair is even
Bar assembly is along 31 center symmetric setting of screw rod, so that remaining vertical in 352 action process of vertical connecting rod.In this way, motor is opened
Qi Hou will drive screw rod to rotate around Pivot Point Center first, so that nut seat is moved in a straight line along screw rod, i.e., so that nut seat and solid
Reservation is moved closer to or is gradually distance from；So that two vertical connecting rods move closer to or separate, and then finally in two companies
Under the influence of bar assembly, so that sliding block rises or falls movement.In the process, on the one hand, due to using motor conduct
Therefore power source has many advantages, such as that machining accuracy is high, processing effect is good on the whole；On the other hand, the rotation fortune of screw rod
The transmitting of link assembly is passed through in dynamic, nut seat horizontal movement, will have nonlinear motion characteristic, to have in idle stroke
Quickly, the characteristics of being lightly loaded, have the characteristics that in bending process at a slow speed, it is heavily loaded, meet bending working condition requirement, so that this case can have
There are bigger, more stable bending power and higher bending efficiency.Simultaneously as a pair of links component is set along screw rod central symmetry
It sets and upper connecting rod and lower link is isometric；Therefore, upper connecting rod, will to the vertical component of vertical connecting rod directed force in two link assemblies
Equal to lower link to the vertical component of vertical connecting rod directed force, but the two is contrary, thus finally will be so that vertical connecting rod pair
The active force of screw rod there will be only in horizontal direction, i.e., so that the power that is subject to of screw rod is only along its axial direction, and then effective protection silk
There is the phenomenon that bending, card resistance after avoiding screw rod long-time use in bar.Therefore, this case effectively combines large-tonnage bending machine
The advantages of with both digital controlled servo bending-machines, have that machining accuracy is high, processing effect is good, motion stability, bending on the whole
The advantages that power is big and structural stability is good, long service life.
Representative elaboration is carried out to vertical holding mechanism in the form of two kinds of embodiments below:

Embodiment one, as shown in figs. 4-7, the fixing seat are linked together with one of them vertical connecting rod, the nut seat and another
One vertical connecting rod is fixedly connected.Amount of parts is minimum in the embodiment, structure is simplified the most.
Embodiment two, as shown in figs. 12-15, the fixing seat and one of them vertical connecting rod be hinged and the vertical connecting rod
Side be equipped with Synchronization Component；The nut seat and another vertical connecting rod be hinged and the side of the vertical connecting rod also is provided with together
Walk component.Amount of parts is most in the embodiment, but assembly difficulty is minimum.
Embodiment three, as shown in figure 19, the fixing seat and one of them vertical connecting rod be hinged and the vertical connecting rod one
Side is equipped with Synchronization Component, and the nut seat is fixedly connected with another vertical connecting rod.Amount of parts is moderate in the embodiment, together
When assembly be not difficult and structure is more simplified.
Example IV, as shown in figure 20, the fixing seat are fixedly connected with one of them vertical connecting rod, the nut seat with
Another vertical connecting rod is hingedly and the side of the vertical connecting rod also is provided with Synchronization Component.Similarly with embodiment three, in the embodiment
Amount of parts is moderate, while assembly difficulty is not high and structure is more simplified.Simultaneously as the side where fixing seat is more leaned on
Nearly motor, therefore, fixing seat, which is fixedly connected with one of them vertical connecting rod, can reduce motor, screw rod, between transmission belt three
Assembly difficulty.
