Dust collecting system 10 is used to absorb flue dust when laser cutting plate, and panel surface cleaning systems 11 are for cleaning laser cutting machine 8
Two-sided, the guarantee product quality of the finished product plate of output, while preventing contaminants subsequent production line.
Laser cutting machine 8 is sequentially connected with material feeding belt feeder 12 and magnetic stacking machine 13, and the side of material feeding belt feeder 12 is equipped with
The outlet of mechanical hand 14, magnetic stacking machine 13 is connected with waste material bucket 15.The finished product plate of 8 well cutting of laser cutting machine enter by
Expect belt feeder 12, is then sent to the progress stacking of magnetic stacking machine 13 if plate is steel plate, become product after packaged；If plate is
It is aluminium sheet, stacking is carried out by mechanical hand 14, becomes product after packaged.Waste material bucket 15 is used to collect the waste material of discharge.
The part Layout being illustrated in figure 3 in the present embodiment, correspondingly, laser cutting machine 8 includes the fortune along plate
First laser cutting head 801, second laser cutting head 802 and the third laser cutting head 803 that dynamic direction is set gradually.First swashs
Light cutting head 801 is cut in 1# cutting area cutting waste materials, second laser cutting head 802 in 2# cutting area cutting waste materials, third laser
It cuts first 803 and enters material feeding belt feeder 12 in 3# cutting areas cutting waste material or cut-out plate, the plate of cut-out.
The special Cutting platform 9 that part Layout as shown in figure 3 is mutually applicable in, as shown in figures 4 and 9, according to coiled strip
Width adjusts the positioning of mobile locating wheel 903, adjusts portable roller item 902 according to the position of waste material and movable type is horizontal
The position of beam 904 accordingly forms respective blanking port in 1# cutting areas and 2# cutting areas, and waste material is completed after cutting directly from blanking
Mouth falls into lower section scrap collecting tank 17.
The course of work of above-mentioned step-by-step movement laser cutting Decoiling ＆ blanking Iine in modern is：Coiled strip (coil of strip or aluminium volume) is on uncoiler 1
Expansion, after being introduced into four-roller pinch machine 2, cuts 3 using material head and cuts the bad plate in coiled strip head, four-roller pinch machine 2 continues to pinch
Leveling in plate to level(l)ing machine 4, first passing through kink 5, (7 upper roller of sizing feed machine has been at this time to Ce Dao mechanisms 6 and sizing feed machine 7
Lift), after Ce Dao mechanisms 6 position plate centering, 7 upper roller of sizing feed machine depresses plate, and 5 platform of kink is down to the hole of kink 5
Bottom, uncoiler 1, four-roller pinch machine 2, level(l)ing machine 4, which continue to pinch plate to kink 5 forward, cheats, and plate cheats interior shape in kink 5
At kink, so far coiled strip completion threading work.
Continue to send plate to the working region 1# cutting areas (first of the first laser cutting head 801 of laser cutting machine 8
Step), according to the Layout of part, first laser cutting head 801 cuts away corresponding waste material (as shown in Figure 5) in 1# cutting areas；Root
According to step pitch specified in part Layout, sizing feed machine 7 is sent again after the plate of a step pitch length (second step), first laser
Cutting head 801 continues to cut away corresponding waste material in 1# cutting areas；Sizing feed machine 7 send a step pitch (third step) again, and plate arrives
Up to the working region 2# cutting areas of second laser cutting head 802, the continuation of first laser cutting head 801 is cut away accordingly in 1# cutting areas
Waste material, while according to the Layout of part, second laser cutting head 802 starts to cut away corresponding waste material (such as in 2# cutting areas
Shown in Fig. 6)；Sizing feed machine 7 continues to send the plate (the 4th step) of a step pitch length, first laser cutting head 801 and second
Laser cutting head 802 continues to cut away respective waste material in respective working region；Sizing feed machine 7 send a step pitch again
(the 5th step), plate reach the working region 3# cutting areas of third laser cutting head 803, are swashed according to the Layout of part, first
Light cutting head 801 and second laser cutting head 802 continue to cut away respective waste material in respective working region, at the same time
Third laser cutting head 803 starts to cut off plate in 3# cutting areas, for the first time cut-off material head portion according to the Layout of part
It is allocated as directly draining into waste material bucket 15 (as shown in Figure 7) forward for front end waste material；So far three laser cutting heads have been gradually completing respectively
From the cutting of waste material and the cut-out work of plate.
Sizing feed machine 7 send the plate of a step pitch length, the automatic production model of sliver to start again, first laser cutting
First 801 and second laser cutting head 802 cut away respective waste material, third laser cutting head 803 in respective working region
Plate, first piece of qualified finished product plate discharge (as shown in Figure 8) are cut off in its working region；Finished product plate is by material feeding belt feeder
12, which are delivered to magnetic stacking machine 13, carries out stacking；The continuous circulating repetition above process, qualified plate are constantly discharged, material feeding skin
Constantly the part of well cutting is sent to magnetic stacking machine 13 with machine 12 and carries out stacking；If coiled strip is aluminium volume, magnetic stacking machine 13
It does not work, mechanical hand 14 works, and aluminium sheet is carried out stacking using terminal-collecting machine.
It should be noted that due to the structure size of laser cutting machine, step pitch is less than the part of 1000mm, scale
Feeder will send five step pitches, three cutting heads that could complete respective cutting；It is more than the part of 1000mm if it is step pitch, it is fixed
Ruler feeder can complete respective cutting as long as sending three cutting heads of step pitch three times.
The present invention is not limited to above-mentioned optional embodiment, anyone can show that other are each under the inspiration of the present invention
The product of kind form.Above-mentioned specific implementation mode should not be understood the limitation of pairs of protection scope of the present invention, protection of the invention
Range should be subject to be defined in claims, and specification can be used for interpreting the claims.
