[0002] The function of automobile airbags is to store high-pressure inert gas and gas-generating medicine. When an automobile accident occurs, the ignition coil triggers the explosion of the gas-generating medicine. The high pressure generated will break the sealing plug at the end of the steel tube, instantly filling the airbag and protecting the human body from harm. Different airbags are used according to different models. For this reason, the steel tube that carries the airbag needs to be cut and grooved as needed.

[0003] In order to improve cutting accuracy and efficiency, laser cutting is generally used. However, in the existing steel pipe cutting and grooving device, the steel pipe to be cut is placed on the workbench for fixation, and then taken out. Then the equipment stops and lowers the cut steel pipe to take out and place the cut steel pipe. The whole process is complicated and inefficient.

[0004] For this reason, we propose a steel pipe cutting and grooving device for automobile airbags. Summary of the invention

[0028] Working principle:

[0029] When the present invention is in use, firstly, the steel pipe is stacked on the top of the storage block 8. Since the top of the storage block 8 is designed to be inclined, the steel pipe relies on one side of the feeding plate 9 along the inclined surface. At this time, the motor 26 and the conveyor belt 5 are started at the same time. The motor 26 drives the turntable 27 and the shifting block 28 to rotate. At this time, the transverse groove 29 on the feeding plate 9 is driven by the shifting block 28, so that the feeding plate 9 is stably lifted and lowered in cooperation with the stabilizing groove 31 and the stabilizing bar 30. When the feeding plate 9 drops to the lowest point, the inclined surface on the feeding plate 9 is lower than the steel pipe, and the steel pipe rolls down on the feeding plate 9 along the slope. At this time, the steel pipe relies on the L-shaped guide plate 10 along the slope of the feeding plate 9. When the feeding plate 9 is at the highest point, the steel pipe falls into the placement groove 7 along the slope of the feeding plate 9. Since the placement groove 7 is also inclined, the steel pipe still relies on one side of the limit plate 22 (rotatable according to the diameter of the steel pipe). The handle 24 causes the threaded rod 23 to drive the limit plate 22 to slide, so that the part of the steel pipe that needs to be cut is exposed to the loading block 6 for cutting). As the conveyor belt 5 continues to move, the spherical block 21 begins to cooperate with one side of the guide plate 32, so that the extension rod 20 is stretched. At this time, the first rack 14 drives the stopper 19 to compress the spring 18 and starts to move. At this time, the first rack 14 drives the gear 13 to rotate, so that the second rack 15 also moves together, so that the two clamping blocks 16 are close to each other to fix the steel pipe. After fixing, start the laser cutting equipment 4 to cut and groove a certain part of the steel pipe.
