Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a stainless steel pipe laser cutting device. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also often used as furniture and kitchen utensils. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Stainless steel laser cutting is a precise and efficient process that uses a high-power laser beam to cut stainless steel sheets. The laser beam melts and vaporizes the stainless steel material and focuses on a specific point to achieve clean and accurate cutting. The process is highly controlled and can achieve complex designs with sharp edges and fine details.

[0003] Laser cutting machines produce harmful smoke during operation, which will damage the health of the operator and surrounding personnel and cause environmental pollution. For laser cutting in workshops, existing laser cutting technology generally uses local smoke treatment plus comprehensive workshop ventilation to reduce and eliminate the impact. This method is less effective in eliminating the harm caused by smoke, and a large number of sparks are inevitably generated when laser cutting stainless steel pipes. Therefore, it is necessary to design a stainless steel laser cutting device that can absorb and filter harmful dust. Utility Model Content

The right end of the fixed block 50 on the right side of the water tank 1 is fixedly installed with the first connecting member 51, and the hand crank 53 is rotatably installed on the front side of the first connecting member 51. The left end of the hand crank 53 is welded with a bevel gear 52.

[0025] like Figure 1-Figure 3As shown, the pushing mechanism 11 includes a ring gear 112, a clamping member 115, a pinion 111, a motor 110, a support platform 116, a slider 118 and an electric slide rail 117. The ring gear 112 is rotatably installed in the middle of the top front side of the dust suction plate 12, and a connecting block 113 is fixedly installed in an annular shape on the inner side of the ring gear 112. The front ends of the connecting blocks 113 are fixedly connected to springs 114, and the front ends of the springs 114 are fixedly installed with clamping members 115.

A support platform 116 is fixedly installed on the rear side of the top of the dust suction plate 12, and an electric slide rail 117 is fixedly installed on the left side of the inner wall of the outer frame 8. A slider 118 is slidably installed in the slide groove of the electric slide rail 117, and the slider 118 cooperates with the support platform 116.

[0026] When laser cutting stainless steel pipes, since the required cutting length varies, a limiting mechanism 5 is required to limit the cutting length of the stainless steel pipe. Before cutting, the worker needs to manually hold the rocker 53 to drive the bevel gear 52 to rotate, and at the same time drive the threaded rod 54 to rotate. Under the rotation of the threaded rod 54, the guide rod 57 is driven to slide at the same time. At this time, the position of the limit plate 56 can be adjusted. The required cutting length of the stainless steel pipe can be accurately measured according to the cooperation of the ruler 14 installed on the right side of the loading frame 2 and the pointer 15 installed on the second connecting piece 55 on the right side of the limit plate 56. After the measurement is completed, release the rocker 53. After the worker has measured the required cutting length of the stainless steel pipe, when it is necessary to perform laser cutting on the stainless steel pipe, first, he pulls out the blocking block 3 by hand, pours in an appropriate amount of smoke absorbent, and at the same time connects the water pipe to the water pipe 4 to fill with water. At this time, the smoke absorbent and water are fused, and then the blocking block 3 is plugged back, and the sliding door 7 handle is held and the sliding door 7 is pulled out to the rear side, and then the stainless steel pipe is placed on the support platform 116 in the outer frame 8, and the sliding door 7 handle is held again and the sliding door 7 is pushed forward to reset. At this time, the electric slide rail 117 is started and the slider 118 is pushed forward, so as to achieve the effect of simultaneously driving the stainless steel pipe to be pushed forward to the inner side of the gear ring 112. When the stainless steel pipe is pushed to the position consistent with the adjustment When the limit plate 56 with a good distance contacts, close the electric slide rail 117. At this time, the clamping piece 115 on the ring gear 112 clamps the stainless steel pipe under the action of the spring 114, and then start the motor 110. The output shaft of the motor 110 drives the pinion 111 to rotate, and the pinion 111 then drives the ring gear 112 to rotate. At the same time, the ring gear 112 drives the stainless steel pipe to rotate, and the laser cutter 9 is started to cut the front part of the stainless steel pipe. The cut stainless steel pipe will automatically fall into the loading frame 2, and then start the electric slide rail 117 again, so that the remaining part of the stainless steel pipe contacts the limit plate 56 with a good distance again. Repeating the above operation can continuously cut the stainless steel pipe.

[0027] During the cutting process of the stainless steel pipe, due to the effect of the protective cover 6, it can be ensured that the harmful smoke generated during the cutting process will not spread into the workshop, but enter the outer frame 8 through the small holes hollowed out on the front side of the outer frame 8. At this time, the vacuum cleaner 10 is started. Under the action of the vacuum cleaner 10, the harmful smoke can be sucked into the water tank 1, and the dissolved liquid in the water tank 1 will then absorb and dissolve the harmful smoke, thereby effectively treating the harmful smoke generated during the cutting process.

[0028] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
