Step 4：Whether the speed for judging currently to set is more than Maximum speed limit speed Vh, if being greater than Maximum speed limit speed,
Continue to judge whether currently processed lines are long lines, if so, pressing Maximum speed limit velocity process current line；If not more than most
High speed limit speed, handle current line；
Step 5：Judge whether also lines are pending in internal memory, if so, continuing executing with step 4, if not having, execution terminates
Work.
After piercing tip 10 is installed on punching cutter head, starts to cut material, be comparatively punched the knife of head
Head frequency is low, and its rotating speed of cutter head motor 31 is 3000r/min, Oscillation Amplitude 25mm, and the piercing tip 10 for being punched head is being rushed
When cutting material, blade leaves material and is punched out, and from the superiors' material, is directly punched into orlop.
The cutter head of punching head forms a blanking process with the peak of blade, minimum point and a track amount of movement,
Punching track, all-rush blanking process are formed by several blanking process continuous cuttings.Because material is only hung down by track
Nogata to power, the cutting force of punching is big, the material of cleavable multilayer.Cutting effect compared to vibration cutter head will get well, bicker
The absorption affinity that head requires is small, and only need to adsorb fixed material can carry out cutting action, and will not also produce cutting to knitting system material draws
The situation of silk.
Wherein, the cutting speed of piercing tip 10=punching frequency * amount of movements, punching frequency is by the cutter head of punching head
The rotating speed of the cutter head motor 31 of lifting structure and determine, the rotating speed of cutter head motor 31 is 3000r/min, the shifting of piercing tip 10
Momentum is determined by the width of knife-blade, and what thus its widths affect piercing tip 10 cuts precision, even if track point
Resolution.
Such as：Assuming that the width of the blade of piercing tip 10 is 4.5mm, then the amount of movement of a cycle is≤4.5mm, is counted
It is 3000r/min*4.5mm ÷ 60s=225mm/s to calculate it and be punched maximum cutting rate；
Assuming that the width of the blade of piercing tip 10 is 8mm, then the amount of movement of a cycle is≤8mm, calculates its punching
Maximum cutting rate is 3000r/min*8mm ÷ 60s=400mm/s；
Thus the cutting speed of punching is if desired accelerated, as long as widening knife-blade width can accelerate to cut.Together
When the present invention the Oscillation Amplitude of piercing tip 10 be 25mm, because piercing tip 10 needs to leave material when returning back to peak
Expect surface, it requires the thickness of cutting multilayer material within 20mm.
Further, the long lines are the lines that length is more than (Vh*Vh-V0*V0)/a, and Vh is Maximum speed limit speed
Degree, V0 is initial velocity, and a is acceleration.
When cutting speed is more than Maximum speed limit speed, continue to judge whether currently processed lines are long lines, if so, by most
High speed limit velocity process current line；According to split requirement, safety coefficient is set as 0.9, the up and down reciprocatingly speed of piercing tip 108
Spend for 50r/s, a width of 6mm. of knife so speed of the Maximum speed limit speed no more than 50*6*0.9=270mm/s.
During the punching head work of the present invention, start cutter head motor 31, rotary drive motor 41 and lead screw motor 51, punching
Cutting edge 10 is installed in the blade holder 11, when needing to adjust whole punching head, the machine head lifting mechanism
Screw mandrel 55 is moved up and down by the lead screw motor 51, through the connecting rod shell 46 in the connecting seat 6 with
The rotation displacement of screw mandrel 55 and move up and down, it is easy to remove to arrive so as to play the whole height for adjusting the upright driving mechanism
Cut above material.When being cut to material, the upright driving mechanism is controlled described by the cutter head motor 31
Eccentric wheel 32 rotates, and then drives the connecting rod 1 of the lower end of connection sleeve pipe 34 to be moved up and down, material is entered so as to realize
Row punching；When material is cut into it is of different shapes when, the rotary drive motor 41 of the rotary drive mechanism can control belt 43
Rotated, the rotation of the rotational band movable belt pulley 42 of belt 43, so as to drive connecting rod 1 to rotate so that piercing tip
10 certain angle that rotates to is cut.Now using punching head cutting, the vacuum adsorption force of its platform need not be very big,
Energy locator material, it utilizes punch press principle, and material is cut down, cut by continuous cutting track by piercing tip 10
Flexible material 12；Material is by the vertical direction that knife is track, rather than track moving direction, therefore material is not in cutting process
It can move, and have an improvement for the effect of multilayer punching print, it is in the same size above and below the print of cutting, it is particularly soft and have
The material (such as knitting system material) of elasticity, solve vibrating blade and cut yielding and cutting multilayer material movement situation, meet user
Production requirement, improve operating efficiency, substantially reduce production cost.
Above procedure inputs related data by peripheral apparatus system and is controlled cutting process, in screw mandrel 55, connecting rod 1
Etc. being provided with sensor near rotary shaft, check that the back to zero situation of each rotary shaft carries out the next step according to sensor.
It is wide according to the knife of the piercing tip 10 used, Maximum speed limit speed Vh is produced automatically in system, is judged by sensor current
Whether the speed of setting is more than Maximum speed limit speed, if being greater than Maximum speed limit speed, continues whether to judge currently processed lines
It is long lines, if so, pressing Maximum speed limit velocity process current line；If not it is more than Maximum speed limit speed, by current setting speed
Spend to handle current line；Then proceed to judge whether also have lines pending in internal memory, if so, rejudging what is currently set
Whether speed is more than Maximum speed limit speed to carry out lower knife cutting material, if not having, cutter is completed, controlling party of the invention
Method embodies automation, intelligent, can repeatedly be cut according to the actual conditions of material, and the effect for completing to cut is preferable, city
Field prospect is considerable.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention can not be construed in any way.Based on explanation herein, the technology of this area
Personnel would not require any inventive effort the other embodiments that can associate the present invention, and these modes are fallen within
Within protection scope of the present invention.
