Specific embodiment
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clearly defining.
Refer to accompanying drawing 1 to 4, the embodiment of the present invention includes:
A kind of synchronous shearing knife group mechanism, including knife group frame 1, upside cutting knife 2, downside cutting knife 3, knife group linkage unit, on
Side guide 4, lower platen 5 and pressing plate cylinder 6.As illustrated, knife group frame 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 respectively positioned on the upside of the table top of workbench 7, and in knife group linkage unit
Rotating shaft 8, capacity eccentric bearing 9 and motor 10 be then fixedly arranged on the downside of the table top of workbench 7, be additionally provided with support in the bottom of workbench 7
Foot 20.
Vertical guide groove 11 is provided with knife group frame 1, upside cutting knife 2 is snug fit in guide groove 11, downside cutting knife 3 level
It is fixed on the lower end of guide groove 11 and coordinate cut-out supplied materials with upside cutting knife 2.Knife group linkage unit then drives upside cutting knife 2 along guide groove
11 slips;Knife group linkage unit is including rotating shaft 8, capacity eccentric bearing 9, connecting rod 12 and motor 10;Motor 10 passes through a change speed gear box
The rotating shaft 8 being fixed with capacity eccentric bearing 9 is driven to rotate, the connecting rod 12 that capacity eccentric bearing 9 is radially connected by it is come in synchronous interaction
Side cutting knife 2 and upper platen 4, the table top that connecting rod 12 passes through workbench 7 from the downside of workbench 7 drives upside cutting knife 2 and upside
Pressing plate 4.
Upside cutting knife 2 includes a mandrel 13 parallel to blade direction, and the end of mandrel 13 is additionally provided with connection connecting rod 12
Connection end 14, be provided between upside cutting knife 2 and connection end 14 for preventing the upside cutting knife that significantly rotates around mandrel 13 of cutting knife 2
Fine setting spring 15.In the present embodiment, the top end face of upside cutting knife 2 is provided with connection projection 16, connects projection 16 and is provided with
Antarafacial coordinates a screw rod perpendicular to the horizontal through hole of mandrel 13, through hole internal clearance.Connection end 14 is provided with the axial direction along mandrel 13
Raised jag, the end of screw rod is fixed on jag, cuts with being set with the screw rod being connected between projection 16 in jag
Spring 15 finely tuned by knife.It can be seen that the cutting knife of upper and lower both sides in cooperation it may occur that blade coordinates deviation
Problem.And now, upside cutting knife 2 then possesses the ability around mandrel 13 minor rotation, cutting knife fine setting spring 15 then can ensure that
The adjust automatically of upside cutting knife 2 rotational variations.Precision when this structure can improve cutting knife cooperation cut-out and cut-out quality,
Blade can also be protected simultaneously.
A piece crossbeam 17 parallel with upper platen 4 is fixed on connection end 14, crossbeam 17 is provided with spring straight down
Expansion link 18, 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
It is respectively positioned on the same side of two pieces of cutting knifes, supplied materials can first pass around pressing plate, entering 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 knife group linkage unit, and lower platen 5 is then vertical by pressing plate cylinder 6
Drive.Therefore it may only be necessary to according to the height of cutting knife come the height of lower platen 5, and upper platen 4 is then by knife group linkage groups
Part to work asynchronously with upside cutting knife 2, can improve the coordination ability of equipment.Especially, make in intermittent transmission and cut-out
In industry, the binder of synchronous cut-out and synchronization, the quality of cut-out can be ensured.This structure being easy to intermittent work can be more
Facilitate the quarantine of quality, it is possible to increase the motility of equipment..
The foregoing is only embodiments of the invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
