Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting equipment, and particularly relates to a slag removal device and a pipe laser cutting machine having the same. Background Art

[0002] Metal pipes are a commonly used metal profile and are widely used in various fields of production and life. The metal pipes produced by metal pipe manufacturing enterprises are relatively long (2 - 5 meters, or even longer), mainly for the convenience of production and transportation. However, in the application process, they often need to be cut into the required length according to the usage requirements.

[0003] With the rapid development of technology, laser cutting machines have emerged. Due to their high cutting accuracy and low pollution, they are widely used in scenarios where a large number of metal pipes need to be cut. However, during the laser cutting process, the generation of metal debris is still inevitable. Most of these debris will adhere to the inner wall of the pipe, bringing great inconvenience to subsequent processing and use, and it is also difficult to clean the debris adhering to the inner wall of the pipe.

[0004] Chinese Utility Model Patent No. CN201921336140.0 discloses a chip removal and positioning device for a metal pipe laser cutting machine. During the cutting process, liquid is sprayed into the chip removal pipe through the infusion pipe of the liquid spraying device to wet the chip removal pipe, achieving cooling and at the same time adsorbing and capturing metal debris. However, after the chip removal pipe adsorbs and captures metal debris, it is necessary to regularly clean the chip removal pipe manually by shutting down the machine, which is very inconvenient to operate and has low work efficiency.

[0005] Secondly, Chinese Utility Model Patent No. CN201921423973.0 discloses a chip removal device for a pipe laser cutting machine. Among them, the rear end port of the chip removal pipe is connected to an air extraction device. A suction pipe is connected to the rear end port, and the other end of the suction pipe is connected to an air extraction pump. The metal debris in the chip removal pipe is sucked away by the action of the air extraction pump. However, during laser cutting work, adding an air extraction pump greatly increases energy consumption, and moreover, it cannot be combined with the liquid spraying device to efficiently cool metal debris. Summary of the Invention

[0043] Referring to Figures 1 to 11 , several embodiments of the slag removal device of the present invention and the pipe laser cutting machine having the same will be given below.

[0044] As Figure 1 , Figure 10 and Figure 11 shown, an embodiment of the present invention provides a slag removal device, which includes a chip removal pipe 100, a positioning mechanism, a slider connecting member 600, a driving device for driving the slider connecting member 600 to move back and forth, and a slag removal knife 200. When a metal pipe is laser cut, the chip removal pipe 100 extends into the metal pipe when the driving device drives the slider connecting member 600 to move, and seals the inside of the metal pipe, so that the metal chips generated during the cutting process enter the chip removal pipe and cannot adhere to the inner side wall of the metal pipe.

[0045] The chip removal pipe 100 is hollow, and its material can be copper. The front end of the chip removal pipe 100 is provided with a top opening 110, which can effectively collect the metal chips generated during cutting when the chip removal pipe 100 extends into the metal pipe to be cut. From a top view, the top opening 110 is U-shaped. The rear end of the chip removal pipe 100 passes through the positioning mechanism and is connected to the slider connecting member 600.

[0046] The slider connecting member 600 can be formed by connecting two upper and lower clamping blocks with screws. The upper clamping block and the lower clamping block tightly clamp the chip removal pipe 100, so that the chip removal pipe 100 can move with the movement of the slider connecting member 600.

[0047] The positioning mechanism is a positioning block 300; the positioning block 300 is provided with a positioning hole 301, the chip removal pipe 100 passes through the positioning hole 301, and the aperture of the positioning hole 301 is adapted to the outer diameter of the chip removal pipe 100. Passing the chip removal pipe 100 through the positioning hole 301 can complete the centering positioning work of the chip removal pipe 100 and make the chip removal pipe 100 move only back and forth, improving the movement smoothness of the chip removal pipe 100.

[0048] In addition, as Figure 6 and Figure 7As shown in the figure, the positioning mechanism includes a mounting plate, an upper positioning wheel 920 and a lower positioning wheel 910; the upper positioning wheel 920 and the lower positioning wheel 910 are rotatably arranged on the mounting plate, and the axial directions of the upper positioning wheel 920 and the lower positioning wheel 910 are horizontally left and right. Specifically, the rotating shafts of the upper positioning wheel 920 and the lower positioning wheel 910 are fixed on the mounting plate. The upper positioning wheel 920 is arranged above the chip removal pipe 100, and the rolling surface of the upper positioning wheel 920 is connected to the top of the chip removal pipe 100; the lower positioning wheel 910 is arranged below the chip removal pipe 100, and the rolling surface of the lower positioning wheel 910 is connected to the bottom of the chip removal pipe 100. The cooperation of the upper positioning wheel 920 and the lower positioning wheel 910 can not only complete the positioning of the chip removal pipe 100, but also reduce the friction between the chip removal pipe 100 and the positioning mechanism.

[0049] In this embodiment, the upper positioning wheel 920 and the lower positioning wheel 910 are also U-shaped / V-shaped pulleys. Two upper positioning wheels 920 are arranged at intervals front and back, and one lower positioning wheel 910 is arranged. The concave rolling surface of the upper positioning wheel 920 contacts the top surface of the chip removal pipe 100, and the concave rolling surface of the lower positioning wheel 910 contacts the bottom surface of the chip removal pipe 100, which can prevent the chip removal pipe 100 from shaking up and down and left and right.

[0050] The slag removal knife 200 is arranged above the chip removal pipe 100; the slag removal knife 200 can be swingably arranged back and forth, and the front end of the slag removal knife 200 can extend into the top opening 110. In this embodiment, the slag removal knife 200 is arranged on the front side of the positioning mechanism, and the rear end of the slag removal knife 200 is hinged to the positioning mechanism. Such a design can save materials and is beneficial to the movement of the slag removal knife 200 along with the positioning mechanism. Of course, a fixed rod can also be set to support the slag removal knife 200, and the slag removal knife 200 is hinged to the fixed rod.

[0051] The slag removal knife 200 is arranged above the chip removal pipe 100. During the rearward movement of the chip removal pipe 100 driven by the slider connector 600, the front end of the slag removal knife 200 always contacts the top surface of the chip removal pipe 100 until the slag removal knife 200 enters the top opening 110; then, using the principle that the slag removal knife 200 automatically swings downward due to gravity, the slag removal knife 200 passes through the top opening 110 and enters the interior of the chip removal pipe 100; since the slag removal knife 200 moves forward relative to the chip removal pipe 100, the metal chips inside the chip removal pipe 100 can be mechanically cleaned, and the metal chips are pushed out from the interior of the chip removal pipe 100 to complete automatic cleaning without manual treatment. And during the forward movement of the chip removal pipe 100, the slag removal knife 200 swings upward due to the action of the top opening 110 until the front end of the slag removal knife 200 contacts the top surface of the chip removal pipe 100, avoiding the influence of the slag removal knife 200 on the operation of the chip removal pipe 100.

[0052] The slag removal knife 200 can be made of metal.

[0053] Specifically, the driving device is a synchronous belt linear module; the slider connecting member 600 is connected to the slide table 540 of the synchronous belt linear module. The synchronous belt linear module includes a slide table 540, a motor 520, and a guide rail 530. When the motor 520 operates, the slide table 540 moves back and forth along the guide rail 530, thereby enabling the slider connecting member 600 to clamp the chip removal pipe 100 and move it back and forth.

[0054] As Figure 1 , Figure 9 shown, the slide table 540 of the synchronous belt linear module is provided with a first mounting seat 510. The first mounting seat 510 is connected to the slider connecting member 600 by bolts; specifically, the top surface of the first mounting seat 510 is provided with a first waist-shaped hole 511; the first waist-shaped hole 511 is horizontally arranged left and right (that is, the two arc ends of the first waist-shaped hole 511 are located on its left and right sides respectively); the slider connecting member 600 is provided with a first connecting screw hole; the first connecting screw hole is correspondingly arranged with the first waist-shaped hole 511. When the slider connecting member 600 is bolted to the first mounting seat 510, the left and right horizontal distance between the slider connecting member 600 and the first mounting seat 510 can be adjusted through the setting of the first waist-shaped hole 511.

[0055] The first mounting seat 510 is connected to the slide table 540 by bolts. Specifically, a second waist-shaped hole 512 is provided on the left side of the first mounting seat 510, the second waist-shaped hole 512 is vertically arranged, the slide table 540 is provided with a second connecting screw hole, and the second connecting screw hole is correspondingly arranged with the second waist-shaped hole 512. When the slide table 540 is bolted to the first mounting seat 510, the height distance between the first mounting seat 510 and the slide table 540 can be adjusted through the setting of the second waist-shaped hole 512.

[0056] By using the first waist-shaped hole 511 and the second waist-shaped hole 512, the left and right horizontal position and the height position of the slider connecting member 600 are adjusted, so that the slider connecting member 600 can install chip removal pipes 100 with different diameters and complete the centering work to enable the chip removal pipe 100 to be accurately inserted into the inner cavity of the pipe to be cut.

[0057] As Figures 2 to 7 , Figure 10 and Figure 11 shown, in some embodiments, the slag removal device further includes a limiting mechanism and a driving mechanism.

[0058] Among them, the limiting mechanism is arranged on the front side of the slag removal knife 200. The limiting mechanism includes limiting plates 800 arranged oppositely left and right; the distance between the two limiting plates 800 is greater than the outer diameter of the chip removal pipe 100, so that the chip removal pipe 100 can move back and forth through the limiting mechanism; and, the distance between the two limiting plates 800 is less than the outer diameter of the metal pipe to be cut, so that the metal pipe to be cut cannot pass through the limiting mechanism, and due to the blocking effect of the limiting mechanism, the metal pipe is separated from the chip removal pipe 100.

[0059] Setting the limiting mechanism on the front side of the slag removal knife 200 can complete the automatic separation of the metal pipe to be cut from the chip removal pipe 100, thus facilitating the slag removal knife 200 to extend into the interior of the chip removal pipe 100 for cleaning metal chips, and there is no need for manual removal of the metal pipe to be cut from the chip removal pipe 100.

[0060] The limiting plate 800 can be a metal plate.

[0061] The driving mechanism is connected to the positioning mechanism and is used to drive the positioning mechanism to move back and forth. The slag removal knife 200 is arranged on the front side of the positioning mechanism, and the rear end of the slag removal knife 200 is hinged to the positioning mechanism; the limiting mechanism is connected to the positioning mechanism, so that the limiting mechanism and the slag removal knife 200 can move together with the positioning mechanism to adjust their front and rear positions relative to the metal pipe to be cut, so as to be applicable to the work of cutting metal pipes with different pipe lengths.

[0062] Specifically, the driving mechanism includes a sliding seat 410, a slide rail 420 and a locking screw 430. The slide rail 420 is horizontally fixed, and the cross-section of the slide rail 420 can be in the shape of an H. The sliding seat 410 is slidably connected to the slide rail 420, and the positioning mechanism is connected to the sliding seat 410 by bolts, so that the sliding seat 410 can move back and forth along the slide rail 420 when pushed by manpower, thereby causing the positioning mechanism to drive the slag removal knife 200 and the limiting mechanism to move back and forth to adjust their front and rear positions, so that the slag removal device can be applicable to the cutting work of metal pipes with different lengths.

[0063] The sliding seat 410 is provided with a screw hole, and the locking screw 430 passes through the screw hole and abuts against the slide rail 420. In this embodiment, two locking screws 430 are provided. The locking screws 430 are vertically screwed into the screw hole and abut against the slide rail 420 to fix the sliding seat 410 to the slide rail 420 to prevent the sliding seat 410 from moving when the chip removal pipe 100 moves back and forth. Using the locking screw 430 is simple in operation and has a good locking effect.

[0064] When cutting a longer pipe, the driving mechanism drives the positioning mechanism, the slag removal knife 200, and the limiting mechanism to move backward a certain distance, and uses the locking screw 430 for locking. When cutting a shorter pipe, the driving mechanism drives the positioning mechanism, the slag removal knife 200, and the limiting mechanism to move forward a certain distance, and uses the locking screw 430 for locking. The driving mechanism is provided to adjust the positions of the positioning mechanism, the slag removal knife 200, and the limiting mechanism so that they are as close as possible to the end of the pipe to be cut. In this way, it can be avoided that the chip removal pipe 100 moves backward too far during the slag removal process, resulting in an increase in the energy consumption of the driving device and a reduction in the overall pipe cutting efficiency.

[0065] After cutting, the slider connector 600 drives the chip removal pipe 100 to move backward under the action of the driving device. At this time, the cut pipe is sleeved on the chip removal pipe 100 and moves backward with it.

[0066] Then, under the blocking action of the limiting mechanism, the chip removal pipe 100 is automatically separated from the cut pipe; after separation, since the chip removal pipe 100 continues to move backward, the slag removal knife 200 swings downward at the position of the top opening 110 until the bottom end of the slag removal knife 200 contacts the inner wall of the chip removal pipe 100; during the backward movement of the chip removal pipe 100, the slag removal knife 200 will push the metal chips (or slag) in the chip removal pipe 100 out of the chip removal pipe 100 to complete the automatic slag removal work.

[0067] The driving mechanism can also be a linear module or a telescopic cylinder.

[0068] As Figure 10 and Figure 11 shown, the positioning mechanism is provided with a second mounting seat 440, and the second mounting seat 440 is connected to the sliding seat 410 by bolts; specifically, third waist-shaped holes 441 are respectively provided on the front and rear sides of the second mounting seat 440; the third waist-shaped holes 441 are horizontally arranged from left to right; a third connection screw hole is provided on the top surface of the sliding seat 410; the third connection screw hole is correspondingly arranged with the third waist-shaped holes 441. When the sliding seat 410 and the second mounting seat 440 are bolt-connected, the third waist-shaped holes 441 are provided to be able to adjust the horizontal distance from left to right between the sliding seat 410 and the second mounting seat 440.

[0069] Moreover, a fourth waist-shaped hole 302 is provided on the left side surface of the positioning mechanism, the fourth waist-shaped hole 302 is vertically arranged, the second mounting seat 440 is connected to the positioning mechanism by screws, the second mounting seat 440 is provided with a fourth connection screw hole, and the fourth connection screw hole is correspondingly arranged with the fourth waist-shaped hole 302. When the second mounting seat 440 and the positioning mechanism are connected, through the setting of the fourth waist-shaped hole 302, the height distance between the positioning mechanism and the second mounting seat 440 can be adjusted.

[0070] Through the settings of the third waist-shaped hole 441 and the fourth waist-shaped hole 302, the adjustment of the left-right horizontal position and the height position of the positioning mechanism can be realized, so that the chip removal pipes 100 with different pipe diameters can be inserted into the positioning mechanism after being centered.

[0071] In addition, the positioning mechanism is provided with a connecting top plate 230. The slag removal knife 200 is hinged to the connecting top plate 230. Specifically, the connecting top plate 230 is provided with a hinge shaft 240, and the slag removal knife 200 is arranged on the hinge shaft 240 and can rotate around the axis of the hinge shaft 240. The connecting top plate 230 is provided with a fifth waist-shaped hole 231. The connecting top plate 230 is connected to the positioning mechanism by screws. The fifth waist-shaped hole 231 is arranged horizontally from left to right. The top surface of the positioning mechanism is provided with a fifth connecting screw hole, and the fifth connecting screw hole is correspondingly arranged with the fifth waist-shaped hole 231.

[0072] When the connecting top plate 230 is connected to the positioning mechanism, through the setting of the fifth waist-shaped hole 231, the left-right horizontal distance of the slag removal knife 200 can be adjusted, so as to prompt the slag removal knife 200 to be able to insert into the top opening of the chip removal pipe 100.

[0073] As Figure 8 、 Figure 10 shown, the slag removal knife 200 can be assembled by a tool 210 and a tool mounting member 220. The tool mounting member 220 is provided with a mounting groove. And, an adjustment hole 221 is arranged on the right side surface of the tool mounting member 220. When the top end of the tool 210 is inserted into the mounting groove, a screw is screwed into the corresponding adjustment hole 221 so that the end of the screw abuts against the tool 210, thereby ensuring that the tool 210 is firmly fixed in the mounting groove.

[0074] The tool 210 can slide in the mounting groove to adjust the distance that the tool 210 extends out of the mounting groove. If the pipe diameter of the chip removal pipe 100 is larger, the extending length of the tool 210 becomes longer, so that the tool can contact the inner wall of the chip removal pipe 100. Designed in this way, it can be ensured that the tool 210 can extend into the chip removal pipe 100 to remove the metal chips in the chip removal pipe 100 when the chip removal device is installed with chip removal pipes 100 of different pipe diameters.

[0075] As Figure 10 、 Figure 11As shown, the limiting mechanism further includes a connecting base plate 810. Viewed from above, the connecting base plate 810 is L-shaped.

When the connecting base plate 810 is connected to the second mounting seat 440, the height position of the limiting plate 800 can be adjusted through the setting of the sixth waist-shaped hole 811.

[0076] The two limiting plates 800 located on the left and right sides of the slag removal knife 200 are respectively connected to the connecting base plate 810 by screws. Specifically, the limiting plate 800 is provided with a seventh waist-shaped hole 801; the seventh waist-shaped hole 801 is horizontally arranged from left to right, and the seventh waist-shaped hole 801 is correspondingly arranged with the seventh connecting screw hole. When the limiting plate 800 is connected to the connecting base plate 810, the left and right horizontal distance of the limiting plate 800 can be adjusted by using the seventh waist-shaped hole 801, and then the distance between the two limiting plates 800 can be adjusted, so that when installing the chip removal pipes 100 with different pipe diameters, it is ensured that the chip removal pipes 100 can pass through this distance, while the cut pipes cannot pass through this distance, thus completing the automatic separation of the chip removal pipes 100 and the cut pipes.

[0077] In addition, another embodiment of the present invention provides a pipe laser cutting machine, which includes a connecting plate 700 and the slag removal device as described above; the slag removal device is connected to the connecting plate 700; the connecting plate 700 is installed on the pipe laser cutting machine.
