Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is illustrated.The invention discloses a kind of new rolling cut Formula plate shearing machine, this kind of roll-turning plate shearing machine include frame 21, motivation transfer motion part, knife rest shaft portion, synchronous binder part and Gap regulating portion, motivation transfer motion part drives knife rest shaft portion, and knife rest shaft portion drives lower slide 2 to realize the rolling of lower knife Dynamic shearing, in order to ensure the synchronous binder and lower knife between, is designed with synchronous binder part.
Power section includes active powershift gear 5 and the power gear rotating under active powershift gear 5 drives, power gear bag Include power gear 6 and power gear 7, power gear 6 is connected with connecting rod 3 through eccentric stiffener and drivening rod 3 moves, Power gear 7 is connected with connecting rod 4 through eccentric stiffener.
In the present embodiment, power gear 6 is directly engaged with active powershift gear 5, and power gear 7 is engaged with idle pulley 10, lazy Wheel 10 is engaged with power gear 7 again, and the use of idle pulley 10 makes the steering of power gear 6 and power gear 7 contrary.
In the present embodiment, the composition of eccentric stiffener is: the bent axle 8 of power gear has an axle edge of evagination, connecting rod 3 with One end that power gear 6 connects has the centre bore with the axle edge cooperation of evagination, and axle edge constitutes eccentric stiffener with centre bore ⅰ.
In the present embodiment, the composition of eccentric stiffener is: the bent axle 9 of power gear has the axle edge of evagination, connecting rod 4 one end being connected with power gear 7 have the centre bore with the axle edge cooperation of evagination, and axle edge is constituted with centre bore Eccentric stiffener.
Certainly eccentric stiffener and eccentric stiffener also can be using other constituted modes, as long as meeting motion needs.
Frame 21 is provided with upper tool post 1, and upper tool post 1 is provided with upper slitter, and connecting rod 3 and connecting rod 4 are respectively hinged at lower knife On frame 2.When active powershift gear 5 rotates, engagement power gear 6 rotates, in the presence of eccentric stiffener, one end of connecting rod 3 Do eccentric motion, in the same manner, when active powershift gear 5 rotates, engaged transmission idle pulley 10, idle pulley 10 engaged transmission power gear 7, Under eccentric stiffener effect, eccentric motion is done in connecting rod 4 one end.The other end due to connecting rod 3 and connecting rod 4 is all hinged on On lower slide 2, therefore under two connecting rod effects, lower slide 2 does rolling cut motion with respect to fixed upper tool post, and and due to The participation of idle pulley 10, the rotation direction of connecting rod 3 and connecting rod 4 is contrary, and the side force being therefore applied to the both sides of lower slide 2 can Cancel out each other.
The main purpose of adjusting offset mechanism 22 is to realize the regulation of power gear 6 and power gear 7 phase place, And then realize the adjustment of the angle of shear.The concrete structure of adjusting offset mechanism 22 is prior art.
This plate shearing machine also includes specially designed synchronous binder part, and the purpose of synchronous binder is to be not only in that achievable In workpiece both sides, binder, moreover it is possible to realize the synchronous binder action of binder beam 13 and lower slide 2, and can guarantee that pressure to binder beam 13 simultaneously Material straight movement about 13 for the beam, finally ensures good binder effect it is ensured that shear precision.
The synchronous binder part of this plate shearing machine includes V-shaped guiding rail 17 and moves up and down along V-shaped guiding rail 17 Binder beam 13, binder beam 13 is located at the top of knife rest spindle nose 14 of lower slide 2 both sides and against knife rest spindle nose 14.So, instantly During knife rest 2 motion, the knife rest spindle nose 14 on lower slide 2 is cut action on lower slide 2 and is provoked binder in course of action next time Beam 13 and lower slide 2 synchronization action.
Wherein binder beam 13 includes binder part 20, and binder part 20 is arranged symmetrically in the both sides of binder beam 13, binder beam 13 also include the synchronous tooth bar 19 being connected with binder part 20, and synchronous tooth bar 19 is connected with synchromesh gear 18, and synchromesh gear 18 can Rotate is arranged on binder synchronizing shaft.From figure 1, it may be seen that being respectively provided with a synchronous tooth bar 19 in the both sides of binder beam 13, When two synchronous tooth bars 19 move up and down under binder beam 13 drive, two synchromesh gears 18 rotate, and so can ensure binder The straight binder action of part 20, realizes the lifting of binder and shear precision.
Knife rest guiding parts is additionally provided with lower slide 2, knife rest guiding parts includes lower slide friction plate 16, knife rest guides Part also include the back-up roller wheel 12 contacting with lower slide friction plate 16 and with back-up roller wheel 12 coaxial mounted oscillating bearing 11. Oscillating bearing 11 and back-up roller wheel 12 with the use of it is ensured that curvilinear motion track rolling friction when lower slide 2 moves up and down Needs, that is, change the friction type between lower slide 2 and frame 21.
Certainly, described above not limitation of the present invention, the present invention is also not limited to the example above, the art Change, remodeling, interpolation or replacement that those of ordinary skill is made in the essential scope of the present invention, fall within the guarantor of the present invention Shield scope.
