The embodiment provides a laser cutting system, which comprises three parts, namely a feeding machine, a conveying device and a laser cutting machine.

As for the feeder, the feeder has a feeding device, which is referred to as 2019218962004, a feeding device of a pipe cutting machine, so that long pipes stacked in bundles can be separated one by one.

In order to convey the long pipe to the laser cutting machine, the feeding machine is also provided with a pushing device, and the pushing device is provided with a push rod inserted into one end of the long pipe, a chain connected with the push rod and a motor driving the communicating movement.

It is easy to understand, the motor drives the chain to move along the axis direction of the long pipe, or the length direction of the long pipe, and then the long pipe is pushed into the laser cutting machine.

Of course, the pushing device is also provided with two limiting plates arranged in a V shape, so that the chain is located at the bottom of the two limiting plates, and the push rod is located between the two limiting plates.

Therefore, the two limiting plates limit the long pipe, the push rod can be conveniently inserted into the long pipe, and the long pipe can be conveniently limited to move, so that the long pipe can accurately enter the laser pipe cutting machine.

The structure of the pushing device is easy to imagine and is not shown in the figure.

For laser cutters, the laser cutter has an opening towards the feeder, allowing the long tube to enter the inside of the cutter.

A self-rotating chuck is arranged in the laser cutting machine, a long pipe can penetrate through the chuck after entering the cutting machine and then is clamped by the chuck,

above the cutting machine, can set up the laser head, therefore, when the chuck drove the rotation of long tube, the laser head cut the same height of long tube, and when the long tube rotated the round, the laser head also cut a week, just also cut out a nozzle stub.

In the horizontal direction of chuck, still can set up the stopper that a precision translation was moved, pass the chuck back and the stopper butt when the long tube to, confirm the cutting distance, also confirmed the length of nozzle stub.

The structure of the laser cutting machine is easy to understand and to learn from knowledge and material objects in the industry, and therefore, this embodiment is not illustrated.

In this embodiment, conveyor sets up between material loading machine and laser cutting machine for solve the material loading machine return and stop the problem with laser cutting machine when carrying new long tube.

Specifically, the conveying device mainly has a monitoring mechanism 100 and a conveying mechanism 110.

Wherein, monitoring mechanism 100 sets up in the material loading machine and is close to laser cutting machine one side for the existence of monitoring long tube.

That is, when the long tube is pushed to the limit position by the feeding machine, the monitoring mechanism 100 cannot detect the existence of the long tube, so that the feeding machine can be returned to provide a new long tube, and simultaneously, a signal can be sent to move the conveying mechanism 110 instead of the feeding machine, so as to continuously push the long tube to move, so that the laser cutting machine can normally cut the long tube until the feeding machine can push the long tube currently being cut with the new long tube.

Therefore, the waiting of the laser cutting machine is avoided, the productivity of the laser cutting machine is exerted to the maximum extent, and the production efficiency is improved.

In fact, the switching time of the long pipe is reduced from 10 seconds to 4 seconds, the productivity is improved by 18 to 25 percent, and therefore, the productivity is greatly improved.

The calculation method is as follows:

1. actually, the time taken for the switching process is 10 seconds, the time taken for cutting one short tube by the laser cutting machine is 4 seconds, and 6 short tubes of 1 meter can be cut out from one long tube of 6 meters, so that the number of long tubes that can be cut per hour is 3600/(4 × 6+10) — 105.88 in the conventional manufacturing method.

2. When the embodiment is adopted, the length of the short pipe is 1 meter, and the difference between the length of the short pipe and the space size of the conveying device is almost the same, so that only one short pipe can be cut by the laser cutting machine in the switching process, and the switching process and the cutting process are overlapped by the time for cutting one short pipe, so that the number of the long pipes which can be cut per hour is 3600/(4 × 6+10-4) ═ 120.

Therefore, the productivity is improved by 13.3 percent (120-105.88)/105.88.

3. If the length of the short pipe is 0.5 m, the capacity in the old mode is 3600/(4 × 12+10) ═ 62.06 long pipes/h, and in the new mode, the switching process and the cutting process coincide with the time for cutting 2 short pipes, and the corresponding capacity is 3600/(4 × 12+ 10-4) ═ 72 long pipes/h, and accordingly, the capacity is improved by (72-62.06)/62.06 ═ 16%.

4. In practical application, the switching process and the cutting process coincide with the time for cutting 1 to 2 short pipes, so that the yield is improved by 13.3 to 16 percent.

5. Theoretically, because the diameters of the long pipes are different, the time for cutting out one short pipe is different, and therefore the specific numerical value for improving the productivity is influenced, but the time for producing one short pipe is close to the time for cutting out one short pipe by laser cutting, and detailed calculation is not needed.

The monitoring mechanism 100 may be light-sensitive, pressure-sensitive, or other types of specific forms.

When the long tube is not in the position for supporting the rotating frame 150, the rotating frame 150 returns under the action of gravity, so that the first conductive block 160 contacts with the second conductive block 170, the signal circuit is communicated, and the operation of the conveying mechanism 110 is controlled.

In some preferred embodiments, the turret 150 may be provided with a weight block 180, the weight block 180 being used to keep the bottom end of the turret 150 away from the laser cutter.

The first link 210 is connected to the free end of the horizontal rotation arm 190, so that the resistance of the first cylinder 200 to motion can be reduced, and quick adjustment can be realized.

The first cylinder 200 is disposed in a direction in which the first wheel 120 is far away from the laser cutting machine, and the first wheel 120 is further disposed close to the laser cutting machine, so that the first cylinder is suitable for a situation in which the remaining length of the long tube is shorter.

As shown in fig. 1, one horizontal rotation arm 190 is provided with a driven gear 220 coaxially fixed with the first wheel 120, and a driving gear 230 engaged with the driven gear, the driving gear 230 is provided at the rotation center of the horizontal rotation arm 190, and a driving motor 240 is provided below the driving gear 230.

Thus, the first wheel 120 is rotated by the driving motor 240 to transport a long tube.

Meanwhile, the driving motor 240 may be fixed on the mounting plate without affecting the rotation of the horizontal rotation arm 190, and the circuit arrangement of the driving motor 240 does not need to be considered.

When the two horizontal rotation arms 190 rotate, the rotation centers of the two horizontal rotation arms 190 are not changed, and thus the driven gear 250 is kept engaged with the driving gear 230 without affecting the transmission.

As shown, a support roller 130 is further provided on the first wheel 120 on the side close to the laser cutter, and the support roller 130 is freely rotatable, thereby reducing the conveyance resistance of the long pipe.

Meanwhile, the supporting roller 130 can support the long pipe, so that the long pipe is prevented from sagging, and the situation that the first wheel 120 cannot convey the long pipe is avoided.

As shown, the support roller 130 is further provided with a vertical screw, so that the height of the support roller 130 can be adjusted to accommodate changes in the diameter of the long pipe.

Of course, at the pushing device, it should also be able to be adjusted up and down, thereby accommodating diameter specification differences of long pipes.

Accordingly, the first screw 280 is rotated, and thus, the position of the first rack 270 is changed, thereby changing the rotation range of the horizontal rotation arm 190.

In order to make the two horizontal rotation walls rotate in a centering manner, the two horizontal rotation arms 190 may be provided with a first rack 270 and a first screw 280, respectively.

Of course, the two horizontal rotating arms 190 can be engaged with each other, reducing the difficulty of adjustment.
