Cutter sweep of the present invention adopts deformable wire steel wire cutter 10 cutting mode, comprise the supported at three point revolving structure of the sprocket ring 1 that cutting action drives, comprise steel wire cutter and dynamically follow the tracks of guide frame, comprise steel wire identical tension structure, comprise and overcome backlash between sprocket ring 1 and main transmission chain 3 and alternately change the structure of the impact produced.These measures and structure, ensure that cutting mechanism is more reasonable, reduce the distortion of the otch section of the monomer of soft state shale honeycomb, improve the service life of steel wire cutter 10.
The present invention adopts wire steel wire cutter 10 cutting mode of deformable, cuts the monomer blank of soft state shale honeycomb.Which avoid form blade by two knife faces under traditional sense cutter as cutting tool time, must rubbing of two knife faces and otch section both sides.For the monomer blank of cellular section structure, as shown in Figure 8, the very weak and quality particularly soft of each wall portion, in test often will there is the cellular eyelet shutoff of monomer blank in the cutter of traditional sense.Further, in friction feeding, cutter homing action damage blank during cutting.
As shown in Figure 7, in figure, the direction of arrow is steel wire cutter 10 moving direction, and steel wire cutter 10 of the present invention is in incision action, and its steel wire cutter 10 moves along tension direction, composition graphs 1 and Fig. 4, and when during actual cutting, steel wire line is on sprocket ring 1 center, this moves to the right; When steel wire line is under sprocket ring 1 center, this moves left.Test proves, such compound cuts action, to the microcosmic drawing crack distortion controlling otch section, very effectively.
As shown in Figure 7, steel wire cutter 10 of the present invention adopts oblique angle to cut form.Composition graphs 4, steel wire cutter 10, in incision course of action, remains the oblique angle being greater than zero degree with horizontal plane.Test proves, oblique angle incision form, and the sword that effectively improve steel wire cutter 10 reality participation cutting is long, the angle thus the distortion produced on honeycomb when further reducing cutting is collapsed.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, cutter sweep transmission system of the present invention achieves the action needed for cutter sweep: driven by motor drive sprocket 4 illustrates rotation, drive sprocket 4 drives main transmission chain 3, and main transmission chain 3 drives sprocket ring 1, drive sprocket 5 and the gap sprocket wheel 6 that disappears; Drive sprocket 5 drives interlock chain 9, and interlock chain 9 drives driven sprocket 8.In transmission, all chains are equal with the pitch of sprocket wheel, and the chain 9 that links is identical with the cycle that the motion one of sprocket ring 1 is enclosed.
As shown in Figure 1, Figure 2, Figure 3 shows, sprocket ring 1 of the present invention adopts supported at three point revolving structure, cuts in application in the present invention, and sprocket ring 1 is one-directional rotation clockwise.This structure comprises the sprocket ring 1 of structure in figure, comprises three groups of roller 2 parts as supported at three point.This structure vacates larger space in sprocket ring 1 central authorities, carries from inside to outside along sprocket ring 1 axis direction to meet blank 14, and forms cutting zone in this space.
As shown in Fig. 1, Fig. 4, Fig. 5, Fig. 6, the present invention arranges the interlock of sprocket ring 1 and interlock chain 9, and after sprocket ring is driven, steel wire fixator 7, when sprocket ring 1 central right, makes cutting action downwards.After having cut, sprocket ring 1 is rotated further, and in steel wire cutter 10 cutting zone, length shortens gradually, and steel wire fixator 7 is walked around on the left of lower edge to centre of sprocket, and steel wire cutter 10 is avoided monomer and upwards made homing action.Thus, the one way realizing cutter up and down reciprocatingly action is effectively cut.
As shown in Fig. 1, Fig. 4, Fig. 6, the present invention arranges and dynamically follows the tracks of guide frame.This structure comprise arrange steel wire fixator 7, follow the tracks of directive wheel 13, stator wheel 11.Follow the tracks of directive wheel 13 structure as shown in Figure 6, follow the tracks of directive wheel 13 and be connected with interlock chain 9 snapping, under the driving of the coaxial minor sprocket of drive sprocket 5, with the chain 9 that links around chain crop rotation knee-action.Fig. 4 illustrates and dynamically follows the tracks of guide frame, and in figure, steel wire fixator 7 ' is the steel wire cutter fixator position signal running to another location.During cutting, as equal pitch transmission, steel wire fixator 7 " X " to motion projection (i.e. " Y " to decomposition motion), with follow the tracks of the translational speed of directive wheel 13 without big difference, ensure that in cutting dynamically, steel wire cutter 10 be rational by the angle of cut blanks 14, by the cutting instantaneous position of two in Fig. 4, the change of this angle is described, thus realizes the oblique angle cutting form requirement of steel wire cutter 10.During cutting, between steel wire fixator 7 and tracking directive wheel 13, form effective fulcrum of steel wire cutter 10, under the prerequisite of setting up steel wire cutter 10 tension force, ensure the rigidity of steel wire cutter 10.
As shown in Figure 1, the present invention arrange steel wire identical tension structure as.In the cutting process of cutter sweep, between steel wire fixator 7 and stator wheel 6, steel wire cutter 10 length variations is larger.For ensureing in cutting process; the tension force of steel wire cutter 10 can keep the value of setting up; steel wire cutter 10 one end is adopted to connect constant steel wire cutter 10 tension force of gas-pressure adjustable tensioning cylinder 12; this structure had both overcome the cutting deformation because steel wire cutter tension variation causes, and protected again steel wire cutter, extended the steel wire cutter life-span.
As shown in Figure 1, shown in Figure 5, the present invention arranges the gap sprocket wheel 6 that disappears in transmission system, in cutting process, steel wire cutter 10 from be positioned at sprocket ring 1 overcentre to cross sprocket ring 1 center reach lower position conversion time, larger cylinder tension force needed for it, makes the backlash direction between sprocket ring 1 and main transmission chain 3 that instantaneous variation occur.Now, steel wire cutter 10 can bear very large tension impact.The gap sprocket wheel 6 that disappears arranged in this structure, effectively absorbs impact energy, drastically increases the service life of steel wire cutter 10.
