Description
Technical field
The present invention relates to a kind of wedge knife rest, belong to field of mechanical technique.
Background technology
, it is necessary to the movement locus of bending tool be controlled, to reach the requirement of bending angle during to steel plate progress bending.Bending
Knife is typically mounted on knife rest, the motion of driving knife rest is controlled by drive device, to drive the motion of bending tool.In order to realize
Towards the bending of different directions, it usually needs change different benders or use different knife rests, add cost；The opposing party
Face, in the prior art to steel plate bending bending power requirement and the precise requirements of bending angle are difficult to meet needs simultaneously.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided a kind of wedge knife rest, both can be with
The power that larger driving bending tool carries out bending is provided, the range ability of bending tool can be accurately controlled again, meet bending angle
The requirement of degree.
In order to solve the above technical problems, the present invention provides a kind of wedge knife rest, it is characterized in that, including a knife rest and positioned at knife
The mounting bracket of frame both ends support knife rest vertical movement；
Knife rest has the upper and lower two knife rest bars at a distance of a setpoint distance, is respectively used to install a bending tool, bending tool court
Set to the centerline direction of two knife rest bars, blade is towards the side of knife rest；
Two knife rest bars are connected to form supporting part at both ends, the supporting part another side different with installation bending tool
For inclined-plane；The inclined-plane side of supporting part sets a voussoir being vertically movable, and voussoir has one to be engaged with the inclined-plane of supporting part
Cammed surface.
Voussoir drives vertical movement by the first driving means being fixed on mounting bracket.
Voussoir upper end has the projection of a protrusion, sets a through hole on projection, the space between underbump and mounting bracket
Position can accommodate lower first driving means, and the drive shaft of first driving means is stretched into the through hole of projection, fix and connect with voussoir
Connect.
The second drive device driving entirety that mounting bracket is arranged on above mounting bracket by one is in vertical motion.
It is preferred that first driving means use differential servo hydraulic cylinder.
It is preferred that the second drive device uses synchronous servo hydraulic cylinder.
The beneficial effect that the present invention is reached：
The wedge knife rest of the present invention, compact-sized, shared solid space is smaller；Larger driving bending tool can be both provided
The power of bending is carried out, the range ability of bending tool, and the wedge knife rest of the present invention can be accurately controlled again, it is possible to achieve court
Both direction carries out bending up or down, only need to change corresponding bending tool, simple to operate, meets to bending angle
Requirement.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the present invention；
Fig. 2 is the longitudinal sectional view of wedge knife rest one end；
Fig. 3 is voussoir schematic diagram.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figure 1-Figure 3, wedge knife rest 1 of the invention is symmetrical arranged, including a mounting bracket 11 and a knife rest 12.Knife
Frame has the upper and lower two knife rest bars 121 at a distance of a setpoint distance, is respectively used to install a bending tool 2, two bending tools are relative
Set, blade is towards the same side of knife rest.When needing to carry out bending upward, pacify on knife rest bar 121 up
Bending tool 2 is filled, when needing to carry out bending downward, bending tool 2 is installed on the knife rest bar 121 of lower section, it is not necessary to change
Knife rest, it is convenient and swift.
Two knife rest bars 121 are connected to form supporting part 122 at both ends, and supporting part 122 and installation bending tool are different
Another side be inclined-plane 123.The side of inclined-plane 123 of supporting part sets a voussoir 13, and voussoir 13 has one oblique with supporting part
Face 123 is engaged the cammed surface 131 of contact.
The upper end of voussoir 13 has the projection 132 of a protrusion, and a through hole 1321, the lower section of projection 132 and peace are set on projection 132
Lower first driving means 3 can be accommodated by shelving the locus between 11, and first driving means 3 are installed on mounting bracket 11, its
Drive rod is stretched into the through hole 1321 of projection, is fixedly connected with voussoir 13, voussoir 13 is driven vertical fortune by first driving means 3
It is dynamic.
When voussoir 13 moves vertically, the band horizontal movement of movable knife rack 12, moved horizontally the bending tool 2 on knife rest 12,
Moving horizontally for bending tool 2 is converted into by the vertical movement of voussoir.First driving means 3 are contained in voussoir 13 and mounting bracket 12
Between space in, make compact-sized, shared solid space is smaller.
Mounting bracket 11 drives overall be in vertical motion by second drive device 4 for being arranged on the top of mounting bracket 11.Peace
When shelving 11 overall vertical movement, first driving means 3, voussoir 13 and knife rest 12 thereon are together in vertical motion, from
And realize the vertical movement of the bending tool 2 on knife rest 12.
Second drive device 4 is fixed on framework 5, and its drive rod is connected with mounting bracket 11, whole for drive installation frame 11
Body moves vertically.
In order to ensure the synchronism of the end motion of knife rest two, the second drive device 4 uses synchronous servo hydraulic cylinder.First driving
Device 3 uses differential servo hydraulic cylinder.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
