Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, and more specifically, relates to a laser cutting device for circular tubes with stress relief function. Background Technology

[0002] Laser cutting of round tubes has become the preferred method in modern manufacturing due to its high precision and efficiency. It can achieve a cutting accuracy of less than 0.1mm, with a smooth, burr-free cut, a small heat-affected zone, and avoid material deformation. Compared with traditional cutting methods, its efficiency can be increased by 8 to 20 times.

[0003] The current round tube laser cutting equipment still has the following problems: 1. The round tube cannot be automatically preheated before laser cutting, resulting in large stress after laser cutting; 2. The auxiliary support structure cannot automatically scrape and clean the iron filings after resetting, resulting in the iron filings needing additional processing; 3. When the round tube is not accurately positioned, the staff cannot know in time, resulting in the round tube not being able to rotate accurately with the motor, affecting the cutting accuracy of the round tube. Summary of the Invention

[0004] This disclosure relates to a circular tube laser cutting device with stress relief function, comprising a cutting drive component, a stress relief and protection component, a support and cleaning component, a laser cutting component, and a positioning and rotating component. Two electric heating wires heat two stress relief blocks, achieving preheating of the cutting area and effectively preventing subsequent stress generation, thus achieving stress relief. When the control panel controls the output shafts of the two electric telescopic rods b to extend, the chip cleaning plate contacts the mounting base, scraping and cleaning the chips in the mounting base. When the inner end of the positioning screw is not inserted into the circular tube, the positioning screw can push the semi-circular pressing block upward, causing the semi-circular pressing block to automatically press the detection switch, which is beneficial for the operator to reposition the circular tube. This solves the problems of large stress after circular tube laser cutting, the inability to automatically scrape and clean chips after the auxiliary support structure is reset, and the inability of the circular tube to accurately rotate with the motor.

Only when the cutting drive block 104 resets to the left does the chip cleaning plate 303 contact the mounting base 101, causing the chips to slowly move out from right to left.

[0026] In this embodiment of the disclosure, such as Figure 1 , Figure 9 and Figure 10As shown, the positioning rotating component 500 includes: a mounting vertical plate 501, a drive motor b502, a circular positioning cover 503, and a positioning screw 504; the mounting vertical plate 501 is fixedly mounted on the top of the mounting base 101; the drive motor b502 is fixedly mounted on the mounting vertical plate 501, and the drive motor b502 is electrically connected to the control panel 600; the circular positioning cover 503 is fixedly mounted on the output shaft of the drive motor b502; the positioning screw 504 is threaded onto the circular positioning cover 503, and the inner end of the positioning screw 504 is inserted into the circular tube; the positioning rotating component 500 also includes: a positioning detection seat 505, a detection switch 506, and a semi-circular pressing block 507; the positioning detection seat 505 is fixedly mounted on the left side of the mounting vertical plate 501; the detection switch 506 is fixedly mounted on the positioning detection seat 505, and the detection switch 506 is electrically connected to the control panel 600; the semi-circular... The pressing block 507 is fixedly installed on the detection switch 506, and the semi-circular pressing block 507 and the positioning screw 504 are located on the same plane. Specifically, the drive motor b502 is fixedly installed on the mounting plate 501, and the circular positioning cover 503 is fixedly installed on the output shaft of the drive motor b502. When the control panel 600 controls the drive motor b502 to work, the output shaft of the drive motor b502 drives the circular positioning cover 503 to rotate, thus achieving automatic rotation of the circular tube. Furthermore, because the positioning screw 504 is threaded onto the circular positioning cover 503, and the inner end of the positioning screw 504 is inserted into the circular tube, it positions the circular tube, allowing it to rotate precisely with the circular positioning cover 503, ensuring the laser cutting accuracy of the circular tube. The right end of the circular tube to be cut needs to be pre-drilled with a drill bit to ensure that the positioning screw 504 can be inserted into the circular hole at the right end of the circular tube. Furthermore, since the detection switch 506 is fixedly installed on the positioning detection seat 505, and the semi-circular pressing block 507 is fixedly installed on the detection switch 506, and the semi-circular pressing block 507 and the positioning screw 504 are located on the same plane, when the inner end of the positioning screw 504 is not inserted into the round tube, when the circular positioning cover 503 drives the positioning screw 504 to rotate, the positioning screw 504 can push the semi-circular pressing block 507 to move upward, so that the semi-circular pressing block 507 automatically presses the detection switch 506.

[0027] The specific usage and function of this embodiment are as follows: In use, the mounting base 101 is first fixed in place with screws. Then, the laser cutting head 402 is connected to the external cutting equipment, and the fume extraction pipe 403 is connected to the external negative pressure pipe. Next, the control panel 600 is connected to an external power source. Then, the right end of the round tube to be cut needs to be pre-drilled with a drill bit. The right end of the round tube is then inserted into the circular positioning cover 503. The positioning screw 504 is then tightened with a wrench until its inner end is inserted into the round tube. When the inner end of the positioning screw 504 is not... When inserted into the round tube, the circular positioning cover 503 drives the positioning screw 504 to rotate, which in turn pushes the semi-circular pressing block 507 upward, causing the semi-circular pressing block 507 to automatically press the detection switch 506. At this time, the control device of the control panel 600 stops working, and the alarm in the control panel 600 sounds an alarm, which helps the staff to reposition the round tube. The output shafts of the two electric telescopic rods b302 are retracted and reset through the control panel 600, so that the two support balls 305 contact the round tube. The output shafts of the two electric telescopic rods a202 are extended via the control panel 600. At this time, the two stress-relieving blocks 203 contact the outer wall of the round tube, and the two electric heating wires 204 heat the two stress-relieving blocks 203, achieving preheating of the cutting area and effectively preventing the generation of subsequent stress, thus playing a stress-relieving role. Afterwards, the output shafts of the two electric telescopic rods a202 are retracted and reset via the control panel 600. At this time, the two stress-relieving blocks 203 separate from the outer wall of the round tube, and the two electric heating wires 204 stop heating the two stress-relieving blocks 203. The drive motor b502 is started via the control panel 600, waiting for the laser cutting head 402 to complete the cutting of the round tube. The fumes during cutting can automatically enter the fume extraction pipe 403 to prevent the fumes from affecting the health of the workers. The drive motor a105 is started via the control panel 600. When the control panel 600 controls the drive motor a105 to work, the drive screw 103 drives the cutting drive block 104 to move automatically to the right, realizing the automatic change of the cutting position. Then, the above steps are repeated to perform multiple laser cuts on the round tube. After the round tube is cut, the output shafts of the two electric telescopic rods b302 are extended through the control panel 600. The drive motor a105 is restarted through the control panel 600, so that the drive screw 103 drives the cutting drive block 104 to reset to the left. At this time, the iron filings cleaning plate 303 contacts the mounting base 101 and scrapes and cleans the iron filings in the mounting base 101, so that the iron filings are slowly moved out from right to left.
