Fig. 2 is the cutting tool path schematic diagram of the rotary flying shear blanking units in the present embodiment.
The circular motion that cutter is done in flying shear process can be divided into 3 states, state to be cut, synchronous regime, withdrawing state.As shown in Figure 2, in operational process, there is following location point in cutter: A point is the beginning point of reference of punching mechanism, and now cutter is positioned at circular path peak rear, is in state to be cut; B point is the starting point that cutter is engaged with material, from B point, enter synchronous regime, now requires that the horizontal component velocity of cutter strictly equals to send the speed of cutting material; The minimum point that C point arrives for tool motion, now, cutter is engaged with bottom guide track, starts to cut off material; D point is the terminating point that cutter is engaged with material, i.e. the terminating point of synchronous regime, at C point, after cutter cuts off material, servomotor 4 continues to drag cutter and does counterclockwise circular rotation, and cutter is separated with bottom level guide rail, now cutter and material are still in synchronized tracking state, until D point.After D point, cutter starts to enter withdrawing state, again gets back to beginning point of reference A, completes withdrawing, and the die-cut action of whole fixed length completes once, waits for next time die-cut.
The AB segmental arc being in state to be cut is position tracking area, when tool motion is to B point, and the material cut-out point requiring this position just for presetting, material and cutter enter synchronized tracking district subsequently; BD segmental arc is synchronized tracking district, B point starts position when entering synchronized tracking district BD segmental arc for cutter, i.e. biting point, C point is in the position of cut-out point for cutter, D point place cutter is engaged again with material, cutter starts to enter withdrawing state this moment, in synchronized tracking district BD segmental arc, require that the horizontal component velocity of cutter requires strictly to equal feeding speed, and vertically component velocity is different with the requirement of CD segmental arc in BC segmental arc: BC segmental arc requires that the vertical component velocity of cutter reduces gradually, increase gradually, until D point to vertical component velocity during C point being zero, CD segmental arc requirement cutter; DA segmental arc is withdrawing district, die-cut for longer fixed length, needs cutter to wait at starting point A place, die-cut for shorter fixed length, then directly enter AB segmental arc, start next time die-cut.
A control method for rotary flying shear blanking units, comprises the following steps:
Step 1, what arrange material by human-computer interaction interface 11 send the controling parameters such as cutting speed degree and die-cut length, the connecting gear 30 that Control Component 1 controls rotary flying shear blanking units with setting speed by material transferring to punching mechanism;
Step 2, survey long codes device 2 and pulse signal is passed to Control Component 1, high-speed counter 12 pulse signals in Control Component 1 counts, determine material cutting position, Control Component is according to " Speed-position is synchronous " control algolithm, calculate the length that material is passed by, then according to feeding speed, try to achieve the speed pulse signal needing to issue motor servo driver part 3 in real time;
Step 3, Control Component 1 sends steering order to motor servo driver part 3, motor servo driver part drives servomotor running, and servomotor carry its tools does counterclockwise circular motion from A point, and it is corresponding with the cutting position of material at B point that Control Component 1 controls cutter;
Step 4, in synchronized tracking district BD segmental arc, Control Component 1 controls servomotor and does variable motion, and control cutter and do the reduction of vertical component velocity in BC segmental arc, horizontal component velocity keeps the retarded motion of constant (equaling feeding speed); In CD segmental arc, make vertical component velocity increase, horizontal component velocity keeps the accelerated motion of constant (equaling feeding speed), realizing cutter to sending the speed tracing cutting material, completing material simultaneously and cutting;
Step 5, after tool motion to withdrawing district, die-cut for longer fixed length, need cutter to wait at starting point A place, die-cut for shorter fixed length, then directly enter AB segmental arc, start next time die-cut.
Below to the algorithm realizing cutter and speed sync synchronous to material position, be described.
The requirement of foundation practical application condition and control accuracy, select the survey long codes device 2 of corresponding resolution, in the present embodiment, survey long codes device 2 resolution that flying shear blanking units adopts is 2500 lines, the diameter surveying long codes device 2 is d, then the displacement of the material surveyed corresponding to the pulse of long codes device is L 1for:
L 1＝πd/2500
Then, when material displacement is die-cut length L, the umber of pulse that survey long codes device 2 sends is: N coding=L/L 1, the umber of pulse N that the high-speed counter 12 in Control Component 1 sends survey long codes device 2 codingcount, determine to send the cutting position cutting material.
Cutter runs one-period needs Control Component 1 to add up to N to the pulse of servomotor 4,
N＝N AB+N BC+N CD+N DA
=K 1n coding AB+ K 2n coding BC+ K 3n coding CD+ K 4n encoding D A
N coding=N coding AB+ N coding BC+ N coding CD+ N encoding D A+ N wait for
Wherein N aB, N bC, N cD, N dAfor cutter move in corresponding segmental arc time, need Control Component 1 to issue the umber of pulse of servomotor 3; N coding AB, N coding BC, N coding CD, N encoding D Afor cutter move in corresponding segmental arc time, survey the umber of pulse that long codes device 2 sends; N wait forfor cutter is in umber of pulse corresponding to A point stand-by period; K 1, K 2, K 3, K 4for cutter moves in corresponding segmental arc, the umber of pulse that Control Component 1 needs to issue servomotor 4 and the scale-up factor surveyed between umber of pulse that long codes device 2 sends.
The position realizing cutter and material is synchronous
A point is tool motion starting point, and now correlation output step-by-step counting resets lays equal stress on New count, moves to B point need Control Component 1 to issue the umber of pulse N of servomotor 4 by can obtain cutter to output step-by-step counting from A point aB, cutter is when AB segmental arc is moved, and the umber of pulse that survey long codes device 2 sends is N coding AB, in order to ensure that cutter is accurately corresponding at the cutting position of B point and material, N aBthe umber of pulse N sent with survey long codes device coding ABshould meet:
N aB=K 1n coding AB
Wherein K 1for fixed value, before formally cutting, K can be determined by the die-cut experiment of limited number of time 1concrete numerical value, also determine by the program in Control Component 1, then draw N coding ABvalue.
Realize the speed sync of cutter and material
After cutter enters synchronized tracking district BD segmental arc, variable motion done by cutter, i.e. K 2, K 3moment change, by being based upon variation relation in this region, control servomotor 4 do variable motion, make the horizontal component velocity of cutter strictly equal to send the speed of cutting material, reach cutter in this region with the speed sync of material, realize the dynamically die-cut of cutter.
As shown in Figure 2, BC segmental arc in synchronized tracking district BD segmental arc and CD segmental arc are about the diameter symmetry of circular path, corresponding scale-up factor situation of change is symmetrical, cutter is made vertical component velocity in BC segmental arc and is reduced, and horizontal component velocity keeps the retarded motion of constant (equaling feeding speed); In CD segmental arc, make vertical component velocity increase, horizontal component velocity keeps the accelerated motion of constant (equaling feeding speed).Under with K in BC segmental arc 2situation of change be that example is set forth:
As shown in Figure 2, h be corrugated board corner protector thickness and die-cut time cutter expose the excessive amount △ sum of corner protector, according to radius (eccentric throw) e of h and cutting tool path, the central angle a between C, B and synchro angle can be drawn at 2:
cos a = e - h e
Cutter moves to C point from B point and surveys the umber of pulse N that long codes device 2 sends coding BC:
N coding BC=L bC/ L 1=e × sina/L 1
In whole process, material moving linearly, and cutter circles, both pulse equivalencies are unified, when tool motion is to B point, survey first pulse that long codes device 2 sends, and the length that corresponding cutter is walked is l 1, corresponding central angle is θ 1, l 1size is:
l 1 = L 1 cos a = K 21 · 2 πe N
Due to K 2moment changes, therefore in synchronized tracking district BD segmental arc, the cutter corresponding to a pulse surveying long codes device 2 walk length, the angle moment not etc., then the length l that walks of second corresponding cutter of pulse 2for:
l 2 = L 1 cos ( a - θ 1 ) = K 22 · 2 πe N
Because θ 1corresponding length is l 1, then:
In BC segmental arc, the distance l that cutter corresponding to the n-th pulse is walked nfor:
When survey long codes device 2 sends N coding BCduring individual pulse, now cutter reaches cut-out point C point, and cutter is a relative to the central angle that B point is passed by, and this instantaneous point cutting tool path and charge motion track are straight line, so the tool circumferential length corresponding to one, the place pulse of C point is l n encodes BC:
Drawn the situation of change of each pulse in BC segmental arc by above formula, because BC segmental arc and CD segmental arc symmetry, in like manner can obtain K in CD segmental arc 3situation of change, as shown in the formula:
Wherein, L 1for surveying the displacement of the material corresponding to the pulse of long codes device; α is the central angle between B point and C point; N be cutter turn around need Control Component to the pulse of servomotor sum; K 2nand K 3nbe respectively in BC segmental arc in synchronized tracking district BD segmental arc and CD segmental arc, Control Component is to the umber of pulse of servomotor and the scale-up factor surveying the umber of pulse that long codes device sends; E is cutting tool path radius,
Pass through K 2, K 3situation of change, Control Component 1 adjusts servomotor 4 and does variable motion in synchronized tracking district BD segmental arc, ensures that cutter and material meet the horizontal velocity moment in synchronized tracking district BD segmental arc equal.
The determination of the residence time
In synchronized tracking district BD segmental arc, cutter can be obtained by synchro angle a and move to the umber of pulse needing to issue servomotor 4 between C point from B point:
N BC＝a/2π·N
Because in synchronized tracking district BD segmental arc, BC segmental arc and CD segmental arc are symmetrical about circle diameter, so move to the umber of pulse N needing to issue motor between D point from C point at cutter cD=N bC, pass through formula: N=N aB+ N bC+ N cD+ N dA, easily obtain N dA.
In withdrawing district DA segmental arc, N dA=K 4× N encoding D A, K 4defining method and K 1identical, and then draw N encoding D A.
When the die-cut length of material is longer, cutter is needed to wait for the regular hour, then in synchronization zone, in-position AB segmental arc, according to formula: N at A point coding=N coding AB+ N coding BC+ N coding CD+ N encoding D A+ N wait for, show that cutter is waited at the umber of pulse N that the A point stand-by period is corresponding, and then draw the stop schedule time of cutter.
