The specific embodiment
Below in conjunction with specific embodiment the present invention is further elaborated, but protection scope of the present invention is not limited by specific embodiment, is as the criterion with claims.In addition, with under the prerequisite of technical solution of the present invention, any change or change that those of ordinary skills that the present invention did are realized easily all will fall within the claim scope of the present invention.
As Fig. 2, reinforcing bar motion cutting machine shown in Figure 3, it comprises that fairlead 1, frame 2 and 4, two cranks 4 of two cranks are separately fixed on power shaft 16 and the driven axle 17, and power shaft 16 is provided with driving gear 12; Driven axle 17 is provided with driven gear 13, and driving gear 12 is meshed with driven gear 13.Fairlead 1 is located on the frame 2 of a side of axial connecting line of two cranks 4, the opposite side of the axial connecting line of described two cranks 4 is provided with slide block assembly 8, slide block assembly 8 by on win in succession 10 and under win in succession and 14 form, under 14 centerline of winning in succession be provided with chute 15, frame 2 is provided with the chute guide rail 11 that is complementary with described chute 15.Described upper and lower winning in succession is provided with two connecting rods 5 between 10,14, by bearing pin 9 two connecting rods 5 and slide block assembly 8 upper and lower being won in succession 10,14 is movably connected.Slide block assembly 8 is corresponding with the position of fairlead 1, and the other end of two connecting rods 5 flexibly connects by preceding bearing pin 3 and two cranks 4 respectively.On the length direction of described two connecting rods 5, back 3/4ths positions that begin from crank 4 one ends are respectively equipped with the blade 7 that can be interlocked mutually, and blade 7 is fixed on the connecting rod 5 by fixture block 6, make blade 7 more firm, and convenient disassembly.
Described fairlead 1, the line L of its center line and upper and lower 10,14 the center line of winning in succession is vertical and pass the axial connecting line of two cranks 4; This line L is the movement locus of reinforcing bar.That is to say that fairlead 1 and slide block assembly 8 are on the movement locus of reinforcing bar.The movement locus of reinforcing bar passes the mid point of the axial connecting line of two cranks 4, and be beneficial to quick labour-saving like this and cut off reinforcing bar, and the otch rule.
Another embodiment of the present invention as shown in Figure 4 is provided with strip stopper slot 18 on described connecting rod 5; Its length direction is consistent with the length direction of connecting rod 5; This stopper slot 18 is located at the end that is connected of connecting rod 5 and crank 4, is provided with the square position limiting slide block 19 that matches with stopper slot 18 on crank 4; This position limiting slide block 19 is set in the stopper slot 18, and the left and right sides of position limiting slide block 19 is respectively equipped with jackscrew and spring, and this position limiting slide block 19 is fixed on the crank 4 to realize that crank 4 and connecting rod 5 flexibly connect by preceding bearing pin 3.Be respectively equipped with the blade 7 that can be interlocked mutually near on slide block assembly 8 one side positions on described two connecting rods 5, other repeats no more with embodiment 1.
When the present invention specifically used: power shaft 16 drove connected crank 4 and rotates, driving gear 12 on power shaft 16 also rotates thereupon simultaneously, and driving gear 12 drives driven gear 13 rotations, the crank 4 that driven gear 13 drives on the driven axle 17 rotates, and such two cranks 4 have just been realized synchronous rotation.At this moment, reinforcing bar slowly advances after passing fairlead 1, reinforcing bar is along advancing perpendicular to the direction of line between the axle center of two cranks 4, at this moment, rotation along with crank 4, the rotation direction of crank 4 inwardly relatively rotates for the direction of advancing along reinforcing bar, K just shown in Figure 1 is to, two crank 4 drivening rods 5, connecting rod 5 drive two blades 7 gradually separately, move in the chute guide rail 11 of the chute 15 of these 14 bottoms of winning in succession at present on sliding frame 2, and reinforcing bar gradually enter between two connecting rods 5 time, along with the arrival of the rotation period of crank 4, connecting rod 5 rotates along with crank 4, and drawing close gradually, also gradually interlock of blade 7 at this moment.When blade 7 touched reinforcing bar, along with being rotated further of crank 4, blade 7 subvertical cut-out reinforcing bars were finished a work period.Along with being rotated further of crank 4, blade 7 once more gradually separately, enter next work period, so just finish the work of cutting reinforcing bar, just crank 4 turns around, blade 7 interlocks once are one-period.The position of the blade 7 shown in Fig. 2, Fig. 4 is the position of interlock.
The present invention is because adopt connecting rod 5 to drive the form of blade 7, make the movement locus of blade 7 change into ellipse by the circle of prior art, connecting rod 5 drives the shearing that blade 7 is equivalent to scissors, therefore the direction of blade 7 cutting reinforcing bars also approaches vertically, so not only cut laborsaving, also reduced the loss of blade greatly, and blade 7 is provided with a side of close slide block assembly 8 on the connecting rod 5, effect was best when especially blade 7 was arranged on back 3/4ths position of connecting rod 5, so crank 4, connecting rod 5 and blade 7 and active pin shaft 9 have just formed a laborsaving lever construction, fulcrum is exactly a bearing pin 9, cutting is more laborsaving like this, make the pressure of blade 7 and crank 4 reduce greatly, well solved the problem of parts losses.
In addition, in the prior art,, after the reinforcing bar stop motion, will force crank also stuck thereupon when blade touches reinforcing bar,, then be easy to shine into the damage of blade even the damage of crank if continue to cut reinforcing bar by force because be that blade is arranged on the crank.In order to address this problem, the present invention has adopted following solution, just embodiment 2 is described is provided with stopper slot 18 on described connecting rod 5, and stopper slot 18 is located at the end that is connected of connecting rod 5 and crank 4, is provided with the position limiting slide block 19 that matches with stopper slot 18 on crank 4.At this moment, position limiting slide block 19 slides in stopper slot 18, the length direction of the stopper slot 18 of bar shaped is consistent with the length direction of connecting rod 5, and the position limiting slide block 19 on the crank 4 is along with crank 4 motions, after the reinforcing bar stop motion, position limiting slide block 19 of the present invention will withstand the sidewall of stopper slot 18 and promote connecting rod 5 and continue action, continuation action along with connecting rod 5,7 on blade cuts off reinforcing bar thereupon, because the form that connecting rod 5 drives blade is laborsaving lever construction, so even crank 4 is rotated further cutting by force, can blade 7 not cause too big infringement yet, when position limiting slide block 19 was square, effect was best, because square position limiting slide block 19 more helps withstanding the sidewall of stopper slot 18.In addition, stuck in stopper slot 18 for preventing position limiting slide block 19, adopted the left and right sides of position limiting slide block 19 that jackscrew and spring are set respectively, be beneficial to the spacing of position limiting slide block 19 and resetting.
The present invention is simple and reasonable for structure, and is practical, effective, is beneficial to and applies.
