Fig. 1 to Fig. 7 has provided a kind of embodiment of the present invention, and in present embodiment, switchable bidirectional swinging cutting means is made up of the two large divisions, is respectively cutting mechanism and manipulator mechanism.
As shown in Figure 1, cutting mechanism is that vertical swing cuts pattern, compress before comprising layer 10, after compress layer 20 and be clipped between the two cut-off knife layer 30.This structure can reduction equipment overall dimension, reduce weight, dwindle the required extending space of maintenance, better adapt to working environment.
The cutting mechanism ground floor compresses layer 10 before being, upper beam 110, preceding vertical columns 120 and the auxiliary hold-down mechanism of cutting before the preceding primary structure that compresses layer 10 has.Before to put the beams in place 110 be two-part, about respectively one section, be the main bearing beam of whole cutting mechanism, this bearing beam is fixed.The lower end of upper beam 110 was the framework foremost of three-decker before preceding vertical columns 120 was connected.The auxiliary hold-down mechanism of cutting is responsible for when being carried out the cutting action by the cutting object, can be by the cutting object because of not stressed and mobile, this mechanism is by two air cylinder driven of vertically installing, the stiff end of cylinder is on preceding upper beam 110, and entire mechanism can only move up and down under the constraint of preceding vertical columns 120.
The 3rd layer of cutting mechanism also is that backmost one deck compresses layer 20 after being, as shown in Figure 3, the group of this one deck wants structure to have the back to put the beams in place 210 and be connected the back vertical columns 220 of upper beam 210 lower ends, back.Back upper beam 210 is the main stressed parts at rear portion, is fixed, and cut-off knife changement 350 is installed above, and the structure of cut-off knife changement 350 will be described in detail below.Back vertical columns 220 be rearmost end framework in the three-decker and preceding vertical columns 120 together, the moving component in the three-decker is clipped in the middle.The form of whole cutting mechanism is as sandwich biscuits, and the front and back layer is fixed, and the intermediate layer is a moving component.
The second layer of cutting mechanism is a cut-off knife layer 30, and as shown in Figure 2, this one deck compresses in the middle of the layer 20 after being clipped in and compressing 10 and the 3rd layers on layer before the ground floor, this one deck mainly comprise a knife rest 310, two swing arms and cylinders 360.The lower end of knife rest 310 is equipped with blade 320, and described blade 320 is the straight knife sheet.In present embodiment, the transition gradually from small to large of the point of a knife angle of described blade is followed successively by 20 °, and 21 °, 23 °, so can make blade more durable, sharper when cutting thin article, when cutting thick article, resistance is littler.
Two swing arm left-right symmetry distribute, and are respectively swing arm 330 and swing arm 340, and swing arm 330 and swing arm 340 are the swing arm of 1/4 toroidal.The hole 300 that two symmetries are respectively arranged in swing arm 330 and the swing arm 340, each hole are equipped with a pivot pin 354, and the quantity of pivot pin 354 is total up to 4.Put the beams in place before swing arm 330 and swing arm 340 are suspended on by pivot pin 354 is dismountable respectively 110 and the back put the beams in place on 210 the rotating respectively two ends that are installed in knife rest 310, its lower end.Knife rest 310 is to bear the stressed parts of upper suspension and lower blade 320, and knife rest 310 is by 360 controls of a cylinder, and the stress point of cylinder 360 is in the middle of knife rest 310.
In present embodiment, the structure of pivot pin 354 is divided into three sections, and is anterior tapered, and the rear portion is the regular hexagon of band tooth bar.Because pivot pin is divided into three sections, anterior tapered, so success rate and smooth degree can improve pivot pin and switch the time, the rear portion is the regular hexagon of band tooth bar, rotates so can prevent pivot pin.
Because the two ends of knife rest 310 are the following hitch point of two swing arms, swing arm and knife rest 310 have formed a parallelogram sturcutre, and when cylinder 360 stretched out, knife rest 310 was done swing downwards, and when cylinder 360 was regained, knife rest 310 was upwards done swing.Same swing arm once uses some pivot pins wherein to swing with realization, uses hole corresponding in swing arm 330 and the swing arm 340 according to circumstances, can change the direction of motion of the knife rest blade that hangs over swing arm 330 and swing arm 340 belows.In once cutting, the wherein pivot pin of homonymy is used in two swing arms simultaneously, makes to be installed in the swing of two knife rests 310 in the swing arm to some directions.
In present embodiment, as preferred version, the rear portion stiff end of cylinder 360 is enough for the whole stroke that guarantees cylinder 360, and the installation site is all higher than whole cutting mechanism, in the top of device framework.
Cylinder 360 not only is connected the middle of knife rest 310 by pivot pin 354, be used to drive knife rest 310 operations.And two sections both sides that also are distributed in cylinder 360 respectively of preceding upper beam 110, about each one section, the motoricity of swing arm 330 and swing arm 340 is provided by cylinder 360 in the middle of it, no matter left or swing to the right, cylinder all can provide onesize power.
Cut-off knife changement 350 is used to control the rotation of pivot pin 354, and then changes the swaying direction of two swing arms 330,340.Concrete, after being installed in, cut-off knife changement 350 compresses on the layer 20, and certainly, cut-off knife changement 350 is not limited thereto the installation site, compresses before also can being installed on the layer 10.Cut-off knife changement 350 comprises four pivot pins 354, four tumbler gears 353, two reversing shafts 351, two synchronizing wheels 352, reversing motor 355 and auxiliary retaining element, a synchronizing wheel 352 and two tumbler gears 353 are installed on each root reversing shaft, synchronizing wheel guarantees that a reversing shaft wherein drives another root reversing shaft synchronous operation, two tumbler gears 353 drive 354 motions of two pivot pins simultaneously, because the difference of the direction of motion, when wherein two pivot pins of reversing shaft 351 drives passed the swing arm of the second layer, another root reversing shaft drove other two pivot pins and withdraws from from swing arm.Reversing motor 355 is installed in the end of one of two reversing shafts 351, is used to drive the rotation of the reversing shaft that is connected, and drives another root reversing shaft rotation simultaneously by synchronizing wheel.In present embodiment, reversing motor 355 is a heavy-duty motor, and the length process calculating of pivot pin 354 motions, the situation that swing arm comes off can not occur, and the process of commutation is safe and reliable.Because the cut-off knife layer is that bidirectional swinging cuts, has more automation so cut, and can improve and cut precision and cut quality than common unidirectional swing.
The homonymy pivot pin is used in swing arm at every turn, to realize the swing of some directions.After each swing arm upwards resetted, conversion cut direction if desired, need withdraw from a pair of pivot pin that is using, and inserted that another is right.Because the force position of cylinder is in the centre of knife rest, after changing pivot pin, the swaying direction of knife rest will obtain changing.
Put the beams in place before every section and 110 last a top limited block 40 is installed, have stopper slot 410 on the described top limited block 40, the shape of described stopper slot 410 is consistent with the shape of two swing arms, when swing arm 330 and swing arm 340 move upward when cylinder is regained, two stopper slots 410 can perfectly be fitted with two swing arms respectively, can not depart to guarantee being parked at same position of swing arm at every turn.
Lower beam 50 is the least significant end of whole cutting mechanism, bears the downward pressure that cuts generation.The two ends, the left and right sides of described lower beam 50 are respectively arranged with a bottom limited block 60, and described bottom limited block 60 has the trapezoidal of certain number of degrees inclined-plane for the upper surface of horizontal positioned.The lower surface at described knife rest 310 two ends also is respectively the inclined-plane that has certain number of degrees, and the inclined-plane number of degrees of the inclined-plane number of degrees of knife rest 310 and bottom limited block 60 are identical.Be directed downwards when swing towards some at knife rest, on the knife rest inclined-plane of the same number of degrees can with the inclined-plane collision on the limited block, to stop the swing of knife rest.Adjust the position of bottom limited block, just can adjust the hunting range of knife rest and blade, with the precision that cuts of realizing ideal.When conversion cuts direction, the limited block onset of the other end.
On the described lower beam 50 tool section groove 70 is installed, removable tool section is installed in the tool section groove 70.Cut-off knife can be cut on tool section after incision is thoroughly by the cutting object, and the effect of tool section is like chopping block, and is neither too hard, nor too soft, can protect blade can not rupture under huge impact power, because blade can be cut tool section, this also is an easy loss part simultaneously.This equipment uses the tool section of 10 conventional * 10mm, because optimized the position of blade and tool section, do not influencing under the situation that cuts precision, and turning tool section, same tool section can use 8 times (4,2 times every).
In present embodiment, the shape of described swing arm is not limited to 1/4 toroidal, also can be " Y " shape swing arm or the swing arm of " V " shape, corresponding in this shape, have two stopper slots on the described top limited block 40, and the shape of stopper slot is also consistent with " Y " shape swing arm or the swing arm of " V " shape.
When cylinder stretched out, swing arm drove knife rest and moves downward, and spacing by two bottom limited blocks 60, a direction can be used one of them.Limited block top, bottom is the inclined-plane of band certain angle, with the inclined-plane collision of the same angle of knife rest after, keep static, at this moment knife rest can not continue to move downward.Bevel angle on bottom limited block and the knife rest all passes through calculating, no matter when being much, can both guarantee that the bottom limited block does not have a bit motion, adjust the position, the left and right sides of bottom limited block in the power of stretching out of cylinder, just can adjust the upper-lower position of knife rest, realize the degree of depth that cuts with this.Because the momental influence of adjustment is to adjust the upper-lower position that the knife rest of circular motion in the swing arm is adjusted in the side-to-side movement of piece in proper order, so this adjusts the corresponding raising of precision, the raising of depth of cut precision has effectively increased cut-off knife and has reached the edge bearing service life of cut-off knife bottom down.
