Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to accompanying drawing 1 to 4, the embodiment of the present invention comprises:
A kind of synchronous shearing knife group mechanism, comprises cutter shelving 1, upside cutting knife 2, downside cutting knife 3, cutter group linkage unit, upper platen 4, lower platen 5 and pressing plate cylinder 6.As shown in the figure, cutter shelving 1 is vertically arranged on the table top of a workbench 7.Upside cutting knife 2, downside cutting knife 3, upper platen 4 and lower platen 5 are all positioned on the upside of the table top of workbench 7, rotating shaft 8 in cutter group linkage unit, capacity eccentric bearing 9 and motor 10 are then fixedly arranged on the downside of the table top of workbench 7, are also provided with feet 20 in the bottom of workbench 7.
Cutter shelving 1 is provided with vertical guide groove 11, and upside cutting knife 2 is snug fit in guide groove 11, and downside cutting knife 3 level is fixed on the lower end of guide groove 11 and coordinates with upside cutting knife 2 and cut off supplied materials.Cutter group linkage unit then drives upside cutting knife 2 to slide along guide groove 11; Cutter group linkage unit comprises rotating shaft 8, capacity eccentric bearing 9, connecting rod 12 and motor 10; Motor 10 drives the rotating shaft 8 being fixed with capacity eccentric bearing 9 to rotate by a gearbox, capacity eccentric bearing 9 comes cutting knife 2 and upper platen 4 on the upside of synchronous interaction by its radial upper connecting rod 12 connected, and the table top that connecting rod 12 passes workbench 7 from the downside of workbench 7 drives upside cutting knife 2 and upper platen 4.
Upside cutting knife 2 comprises the mandrel 13 that is parallel to blade direction, and the end of mandrel 13 is also provided with the link 14 connecting connecting rod 12, and spring 15 finely tuned by the cutting knife be provided with between upside cutting knife 2 and link 14 for preventing upside cutting knife 2 from significantly rotating around mandrel 13.In the present embodiment, the top end face of upside cutting knife 2 is provided with and connects projection 16, and connect projection 16 and be provided with the horizontal through hole of antarafacial perpendicular to mandrel 13, through hole internal clearance coordinates a screw rod.Link 14 is provided with the axial raised jag along mandrel 13, and the end of screw rod is fixed on jag, jag with the screw rod be connected between projection 16 is set with cutting knife and finely tunes spring 15.As can be seen from the figure, when coordinating, may there is the problem that blade coordinates deviation in the cutting knife of upper and lower both sides.And now, upside cutting knife 2 abilities possessed around mandrel 13 minor rotation, cutting knife fine setting 15, spring can ensure the automatic adjustment of upside cutting knife 2 rotational variations.Cutting knife can be improved from this structure coordinate precision when cutting off and cut off quality, also can protect blade simultaneously.
Link 14 is fixed a crossbeam 17 parallel with upper platen 2, crossbeam 17 is provided with telescopic spring bar 18 straight down, and the lower end of telescopic spring bar 18 connects a root type material 19, and section bar 19 is connected upper platen 4.As figure, two block pressur plates are all positioned at the same side of two pieces of cutting knifes, and supplied materials can, first through pressing plate, enter below cutting knife; After supplied materials pushed down by pressing plate, cutting knife just can incision.Upper platen 4 is also by the upper and lower driving of cutter group linkage unit, and lower platen 5 is then vertically driven by pressing plate cylinder 6.Therefore, only need the height carrying out lower platen 5 according to the height of cutting knife, upper platen 5 is then worked asynchronously with upside cutting knife 2 by cutter group linkage unit, can improve the coordination ability of equipment.Especially, in intermittent transmission and cut-out operation, synchronous cut-out and synchronous binder, can ensure the quality of cut-out.This structure being convenient to intermittent work can the quarantine of convenient quality, can improve the flexibility of equipment.。
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
