[0001] The present invention relates to the technical field of cutting equipment, and more specifically to a high-efficiency laser cutting equipment and method for metal pipe processing. Background Art

[0002] Laser cutting is one of the ways to cut workpieces. Laser cutting uses the generated laser beam to melt the material to be cut, and then blows away the melted material with a high-speed airflow, thereby achieving the effect of cutting the workpiece.

DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention.

[0044] like Figure 1-12 As shown, in one embodiment, a high-efficiency laser cutting device for metal pipe processing is proposed, including a machine base 1, a housing 101, a rotating base 102 and a support frame 103 are installed on the upper end of the machine base 1, a material transport component 2 is arranged in the rotating base 102, a cutting component 3 is arranged in the support frame 103, the material transport component 2 includes a material changing mechanism 21 and a positioning mechanism 22, the cutting component 3 includes a rolling mechanism 31 and a slitting mechanism 32, the material changing mechanism 21 includes a driving column 211, a material changing roller 212, a material storage tank 213 and a support Steel roller 214 and driving column 211 are rotatably connected in the rotating seat 102, material changing roller 212 is installed on the circumferential surface of driving column 211, material changing roller 212 is rotatably connected with housing 101, multiple material storage troughs 213 are arranged in material changing roller 212, multiple groups of supporting steel rollers 214 are rotatably connected in material changing roller 212, a first motor 215 is installed at the lower end of the machine base 1, a driving shaft 216 is installed at the output end of the first motor 215, and the driving shaft 216 is connected with driving column 211 through a first sprocket group 217;

[0045] The rolling mechanism 31 includes a lifting seat 311, a connecting frame 312, a driving rod 313 and a rubber friction wheel 314. The lifting seat 311 is slidably connected to a guide rod installed at the lower end of the support frame 103. The upper end of the lifting seat 311 is connected to the output end of a cylinder 319 installed at the upper end of the support frame 103. The connecting frame 312 is installed at the lower end of the lifting seat 311. A pair of driving rods 313 are rotatably connected in the connecting frame 312. The rubber friction wheel 314 is installed on the circumferential surface of the driving rod 313. A second motor 315 is installed on the surface of the connecting frame 312. A rotating shaft 316 is installed at the output end of the second motor 315. The rotating shaft 316 is connected to the driving rod 313 through a second sprocket set 317. The rotating shafts 316 are connected through a third sprocket set 318.

[0046] The slitting mechanism 32 includes a mounting rod 321, a slider 322, a laser cutting gun 326 and a positioning frame 327. The mounting rod 321 is installed in the connecting frame 312. The slider 322 is installed on the circumferential surface of the mounting rod 321. A screw rod 323 is rotatably connected in the slider 322. The lower end of the screw rod 323 is rotatably connected to an extrusion block 324 that is slidably connected to the slider 322. The extrusion block 324 is fitted with the mounting rod 321. A scale groove 325 is provided on the surface of the mounting rod 321. The laser cutting gun 326 and the positioning frame 327 are both installed at the lower end of the slider 322. The rubber friction wheels 314 are all located in the corresponding positioning frames 327.

[0047] In actual application, the embodiment of the present invention controls the first motor 215 to operate, and the first motor 215 drives the driving shaft 216 to rotate, so that the material changing roller 212 is at a feeding angle, and then the metal pipes can be added to the storage slot 213 in the material changing roller 212. At this time, the metal pipes will be located between the supporting steel rollers 214 for support and storage, and then the material changing roller 212 is controlled to rotate again, so that the added metal pipes face upwards;

[0048] By controlling the operation of the air cylinder 319, the cylinder 319 pushes the lifting seat 311 to move downward, and the lifting seat 311 causes the rubber friction wheel 314 to move downward. According to the outer diameter of the metal pipe and the lowered position of the lifting seat 311, the rubber friction wheel 314 squeezes the metal pipe from above, which can meet the cutting operation of metal pipes with different outer diameters. Then, the second motor 315 can be controlled to operate to drive the driving rod 313 to rotate, so that the rubber friction wheel 314 rotates. At this time, under the action of the supporting steel roller 214 in the material changing roller 212, the metal pipe can be driven to rotate under the action of the friction between the rubber friction wheel 314 and the metal pipe, which is convenient for the subsequent cutting of the metal pipe.

[0049] After the metal pipe rotates, when the lifting seat 311 drives the rubber friction wheel 314 to descend, it will also drive the laser cutting gun 326 to descend, so that the laser cutting gun 326 is close to the metal pipe. At this time, by controlling multiple laser cutting guns 326 to turn on, the metal pipe can be cut at multiple locations at the same time, thereby achieving the effect of efficiently cutting the metal pipe. After the metal pipe is cut, the rubber friction wheel 314 and the laser cutting gun 326 are controlled to move upward and reset, and then the material changing roller 212 can be controlled to rotate again to enter the material replenishment state. After the metal pipe is replenished, the new metal pipe is rotated upward. At this time, the metal pipe that has been decomposed will roll backwards under the action of gravity, completing the effect of automatic unloading.

[0050] In one case of an embodiment of the present invention, the distance between the laser cutting guns 326 can be adjusted by the action of the scale groove 325, and then the length of the metal pipe cut can be adjusted. After the adjustment is completed, by rotating the screw rod 323, the screw rod 323 will press down the extrusion block 324, so that the extrusion block 324 and the mounting rod 321 are tightly fitted, so that the current position of the laser cutting gun 326 can be positioned. At the same time, when adjusting the position of the laser cutting gun 326, the rubber friction wheel 314 can be synchronously pushed to slide on the driving rod 313 under the action of the positioning frame 327, so that the rubber friction wheel 314 is always located on both sides of the laser cutting gun 326. At the same time, the metal pipe can be cut into several sections as needed, and the number of laser cutting guns 326 opened can be adjusted. In addition, by disassembling the connecting frame 312 away from the side of the second motor 315, the number of rubber friction wheels 314 and laser cutting guns 326 can be increased and decreased on the driving rod 313 and the mounting rod 321, so that the device has stronger expansibility.

[0051] like Figure 7 and 8 As shown, as a preferred embodiment of the present invention, the positioning mechanism 22 includes a slide rod 221, a positioning block 222 and a bidirectional screw rod 223. The slide rod 221 is installed in the material changing roller 212. The positioning block 222 is slidably connected on the circumferential surface of the slide rod 221 and is slidably connected to the material changing roller 212. The bidirectional screw rod 223 is rotatably connected in the material changing roller 212, and the positioning block 222 and the bidirectional screw rod 223 are threadedly connected.

[0052] When the embodiment of the present invention is actually used, after the metal pipe is input into the storage trough 213, the bidirectional screw rod 223 is controlled to rotate. At this time, under the guidance of the slide bar 221 on the positioning block 222, the bidirectional screw rod 223 will drive the slide bar 221 to slide in the material changing roller 212, so that the positioning blocks 222 on both sides move inward at the same time, and then push the position of the metal pipe, thereby achieving the effect of correcting the position of the metal pipe, ensuring the accuracy of the cutting size of the metal pipe, and after the position of the metal pipe is corrected, the bidirectional screw rod 223 is controlled to reverse, so that the positioning block 222 is reset.

[0053] like Figure 5 and 6 As shown, as another preferred embodiment of the present invention, the circumferential surface of the bidirectional screw rod 223 is installed with a first gear 224, the circumferential surface of the first gear 224 is meshed with a bidirectional ring gear 225, the first gear 224 is meshed with the inner ring of the bidirectional ring gear 225, a third motor 226 is installed in the rotating seat 102, a linkage shaft 227 is installed at the output end of the third motor 226, and the circumferential surface of the linkage shaft 227 is installed with a second gear 228 meshed with the outer ring of the bidirectional ring gear 225.

[0054] When the embodiment of the present invention is actually applied, by controlling the operation of the third motor 226, the third motor 226 will drive the linkage shaft 227 to rotate, the linkage shaft 227 will drive the second gear 228 to rotate, the second gear 228 will drive the bidirectional ring gear 225 to rotate, and the rotating bidirectional ring gear 225 will drive the first gear 224 to rotate under the action of the inner ring teeth, thereby achieving the effect of driving the reciprocating screw 323 to rotate.

[0055] like Figure 13-18 As shown, as another preferred embodiment of the present invention, a cleaning component 4 is installed in the machine base 1, and the cleaning component 4 includes a cleaning mechanism 41 and a suction mechanism 42. The cleaning mechanism 41 includes a rotating frame 411 slidably connected to the machine base 1 through a guide rod, and a plurality of rotating rods 412 are rotatably connected in the rotating frame 411, and the circumferential surfaces of the rotating rods 412 are fixedly connected with wire brushes 413, one of the rotating rods 412 is connected to the output end of a motor 415 installed on the surface of the rotating frame 411, and the rotating rods 412 are connected by a fourth sprocket set 416, and the wire brush 413 is slidably connected to the supporting steel roller 214, and an electric push rod 414 is installed at the lower end of the machine base 1, and the output end of the electric push rod 414 is fixedly connected to the rotating frame 411.

[0056] When the embodiment of the present invention is actually applied, when cutting metal pipes, the material changing roller 212 is in a stationary state, and the material storage trough 213 below is facing downward. At this time, the motor 415 is controlled to operate, and then under the action of the fourth sprocket group 416, the multiple rotating rods 412 are rotated, thereby driving the wire brush 413 to rotate. Subsequently, the electric push rod 414 is controlled to operate, and the electric push rod 414 will push the rotating frame 411 upward to move, thereby driving the rotating rod 412 to move upward, so that the high-speed rotating wire brush 413 contacts the supporting steel roller 214. At the same time, due to the high-speed rotating wire brush 413, the friction force will drive the supporting steel roller 214 to rotate slowly, so that the dust and impurities on the surface of the supporting steel roller 214 can be cleaned, so that the surface of the supporting steel roller 214 is clean, and dust and impurities are avoided to affect the flatness of the metal pipe during loading and storage.

[0057] In one case of an embodiment of the present invention, after the cutting of the metal pipe is completed, the rotating frame 411 can be controlled to descend and reset to avoid interfering with the subsequent rotational movement of the material changing roller 212.

[0058] like Figure 3 and 18As shown, as another preferred embodiment of the present invention, the suction mechanism 42 includes a mounting frame 421 installed at the lower end of the base 1, and a negative pressure pump 422 and an impurity storage box 423 are installed on the mounting frame 421. The negative pressure pump 422 and the impurity storage box 423 are connected by a connecting pipe 424, and a negative pressure pipe 425 is installed at the input end of the impurity storage box 423. An air suction shell 426 is installed in the base 1, and the end of the negative pressure pipe 425 away from the impurity storage box 423 is connected to the air suction shell 426.

[0059] When the embodiment of the present invention is actually used, after the dust and impurities on the surface of the supporting steel roller 214 are cleaned by the wire brush 413, the negative pressure pump 422 is turned on to generate negative pressure suction in the suction shell 426 to suck away the cleaned dust and impurities, which are then extracted through the negative pressure pipe 425 and stored in the impurity storage box 423.

[0060] like Figure 4 As shown, as another preferred embodiment of the present invention, a loading rack 5 is installed on the upper end of the machine base 1, and the loading rack 5 is located in front of the material changing roller 212. A first connecting roller is rotatably connected inside the loading rack 5, and a loading belt 501 is connected between the first connecting rollers. A plurality of first limiting convex strips 502 are arranged on the surface of the loading belt 501.

[0061] In actual application, the embodiment of the present invention stores metal pipes on the loading belt 501. Under the action of the first limiting convex strip 502, the metal pipes can be neatly arranged to avoid rolling. When the material changing roller 212 rotates to the loading angle, the loading belt 501 can be controlled to rotate so that a metal pipe can be conveyed forward into the storage tank 213, thereby achieving the effect of automatic loading of the metal pipes.

[0062] like Figure 4 As shown, as another preferred embodiment of the present invention, a material unloading rack 6 is installed on the upper end of the machine base 1, and the material unloading rack 6 is located behind the material changing roller 212. A second connecting roller is rotatably connected inside the material unloading rack 6, and a material unloading belt 601 is connected between the second connecting rollers. A plurality of second limiting convex strips 602 are arranged on the surface of the material unloading belt 601.

[0063] In actual application of the embodiment of the present invention, after the metal pipe is cut, the material changing roller 212 is rotated backward, and then the metal pipe falls on the unloading belt 601 under the action of gravity. The unloading belt 601 is rotated to convey the cut metal pipe. At the same time, during the conveying process, the second limiting convex strip 602 can prevent the metal pipe from rolling, so that the conveying process is more stable.

[0064] The embodiment of the present invention also provides a cutting method of a high-efficiency laser cutting device for metal pipe processing, the specific steps comprising:

[0065] Step 1: The metal pipe is placed on the feeding belt 501, and then the metal pipe is conveyed forward by the cooperation with the angle rotation of the material changing roller 212, so that the automatic feeding of the metal pipe can be completed;

[0066] Step 2: By controlling the operation of the rolling assembly, the rubber friction wheel 314 moves downward to squeeze the metal pipe on the material changing roller 212, and then cooperates with the supporting steel roller 214 under the metal pipe to drive the metal pipe to rotate when the rubber friction wheel 314 rotates, which is convenient for subsequent cutting operations;

[0067] Step 3: By controlling the multiple groups of laser cutting guns 326 to start, the laser cutting guns 326 will emit lasers to a point, and with the action of the rotation of the metal pipe, the metal pipe can be cut off at multiple locations, thus completing the efficient cutting of the metal pipe;

[0068] Step 4: When the metal pipe is being cut, the material changing roller 212 is in a stationary state. At this time, the rotating frame 411 below is controlled to rise, so that the wire brush 413 contacts the supporting steel roller 214 at another position. At the same time, the rotating rod 412 rotates at a high speed, so that the surface of the supporting steel roller 214 can be cleaned and brushed off.
