Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] This application provides a slag-blocking device and a laser processing equipment to solve the technical problem that molten slag easily adheres to the inner wall of pipes during pipe cutting.
[0043] In the embodiments of this application, such as Figure 3 and Figure 5 As shown, the slag-blocking device includes a base 1, a drive unit 2, a cantilever 3, a connecting rod 4, and a slag-blocking component 5. The drive unit 2 is mounted on the base 1. One end of the cantilever 3 is located at the output end of the drive unit 2. The drive unit 2 drives the cantilever 3 to move along a first direction, which is perpendicular to the length direction of the cantilever 3. The connecting rod 4 is located at the end of the cantilever 3 away from the output end of the drive unit 2, and its length direction is parallel to the first direction. The slag-blocking component 5 is located at the end of the connecting rod 4.
[0044] like Figure 2 and Figure 3 As shown, when the laser beam is used to cut the pipe 60, the drive unit 2 can be controlled to drive the cantilever 3 to move along the first direction, and then the cantilever 3 drives the connecting rod 4 to move along the first direction. Finally, the connecting rod 4 drives the slag-blocking component 5 to move along the first direction, so that the slag-blocking component 5 can extend into the pipe 60.
[0045] When the slag-blocking component 5 extends into the pipe 60 and is located at the cutting position of the laser beam, the slag-blocking component 5 can block part of the inner wall of the pipe 60. By blocking the molten slag, the amount of molten slag adhering to the inner wall of the pipe 60 can be reduced, thereby improving the yield of the pipe 60.
[0046] In this embodiment, the drive unit 2 is disposed on the base 1, one end of the cantilever 3 is disposed at the output end of the drive unit 2, the connecting rod 4 is disposed at the other end of the cantilever 3, and the slag-blocking component 5 is disposed at the end of the connecting rod 4, so that the drive unit 2 can drive the slag-blocking component 5 to move along the first direction through the cantilever 3 and the connecting rod 4 to extend into the pipe 60 to block slag, thereby reducing the amount of molten slag adhering to the inner wall of the pipe 60; since the connecting rod 4 is disposed at the end of the cantilever 3 away from the output end of the drive unit 2, interference of the drive unit 2 with other external components can be avoided.
[0047] In one embodiment, such as Figures 2 to 4 As shown, the slag-blocking device also includes a stop 6, which is disposed on the base 1. The length direction of the stop 6 is parallel to the length direction of the cantilever 3. The stop 6 extends toward the movement trajectory of the slag-blocking component 5, and avoids the movement trajectory of the slag-blocking component 5. The stop 6 and the slag-blocking component 5 are located on the same side of the cantilever 3.
[0048] The stop 6 is disposed on the base 1, so the stop 6 is stationary relative to the base 1. The stop 6 extends toward the moving trajectory of the slag-blocking member 5, so that the stop 6 is directly opposite the end of the pipe 60, facilitating the stop 6 to block the end of the pipe 60. The stop 6 avoids the moving trajectory of the slag-blocking member 5, allowing the slag-blocking member 5 to pass over the stop 6 and extend into the pipe 60 to block slag.
[0049] After the slag-blocking component 5 extends into the pipe 60 and cuts the pipe 60 using a laser beam, the drive unit 2 can be controlled to move the slag-blocking component 5 along the first direction via the cantilever 3 and connecting rod 4, so that the slag-blocking component 5 exits the interior of the pipe 60. During the process of the slag-blocking component 5 exiting the interior of the pipe 60, the stop component 6 will block the end of the pipe 60 to prevent the pipe 60 from getting caught on the slag-blocking component 5 and moving along the first direction with the slag-blocking component 5.
[0050] In one embodiment, such as Figure 2 and Figure 5As shown, the slag-blocking device also includes a guide member 7, which is located at the end of the slag-blocking member 5 away from the connecting rod 4. The width of the guide member 7 gradually decreases in the direction away from the connecting rod 4 so that the edge of the guide member 7 is inclined.
[0051] During the process where the control drive unit 2 moves the slag-blocking component 5 along the first direction via the cantilever 3 and connecting rod 4, causing the slag-blocking component 5 to extend into the pipe 60, the guide component 7 will extend into the pipe 60 first. During the process of the guide component 7 extending into the pipe 60, the inclined side of the guide component 7 has a guiding function, allowing the slag-blocking component 5 to quickly extend into the pipe 60 even if there is an error between the center of the slag-blocking component 5 and the center of the pipe 60 and they are not aligned.
[0052] In one embodiment, such as Figure 5 As shown, the guide 7 is a tapered member, which allows the guide 7 to have a guiding effect in any direction in space, further improving the guiding effect of the guide 7.
[0053] In one embodiment, such as Figure 5 As shown, the cross-sectional profile of the slag-blocking component 5 is partially the same as that of the connecting rod 4, and the slag-blocking component 5 is integrally connected to the connecting rod 4. This facilitates the manufacture of the slag-blocking component 5 and the connecting rod 4, eliminating the need for the step of connecting the slag-blocking component 5 to the connecting rod 4.
[0054] In this embodiment, the slag-blocking component 5 is obtained by cutting the end of the connecting rod 4 once along its axial direction and once along its radial direction. That is, the end of the connecting rod 4 is cut in half, and the part left after the half-cut is the slag-blocking component 5.
[0055] In another alternative embodiment, such as Figure 2 and Figure 3 As shown, the slag-blocking component 5 has a plate-like structure and is detachably mounted on the connecting rod 4. This allows the user to replace the slag-blocking component 5 according to actual working conditions. The size of the slag-blocking component 5 can be selected according to actual needs, thereby improving its applicability.
[0056] In one embodiment, such as Figure 3 and Figure 5 As shown, at least two cantilever arms 3 are provided, and the cantilever arms 3 are spaced apart along the first direction. This can distribute the pressure of the connecting rod 4 on a single cantilever arm 3, thereby improving the stability of the cantilever arm 3 in fixing the connecting rod 4.
[0057] In one embodiment, such as Figures 2 to 4As shown, the slag-blocking device also includes a first pressure block 8 and a second pressure block 9. Both the first pressure block 8 and the second pressure block 9 are mounted on the cantilever 3, and their fixed positions on the cantilever 3 are adjustable along a second direction. An adjustment hole 31 is provided at the end of the cantilever 3 furthest from the output end of the drive unit 2. The cross-sectional dimension of the adjustment hole 31 is larger than that of the connecting rod 4. The connecting rod 4 passes through the adjustment hole 31 and is located between the first pressure block 8 and the second pressure block 9. The second direction is perpendicular to the first direction.
[0058] After the connecting rod 4 passes through the adjusting hole 31, its position within the adjusting hole 31 can be adjusted according to the centerline of the pipe 60 so that the centerline of the connecting rod 4 coincides with the centerline of the pipe 60, facilitating the insertion of the slag-blocking component 5 into the pipe 60. Then, the first pressure block 8 and the second pressure block 9 are moved along the second direction, bringing them closer to the connecting rod 4. After the first pressure block 8 and the second pressure block 9 clamp the connecting rod 4, they are then fixed to the cantilever 3. Thus, the connecting rod 4 is fixed to the cantilever 3 by the first pressure block 8 and the second pressure block 9.
[0059] In one embodiment, such as Figures 2 to 4 As shown, the slag-blocking device also includes a first fixing member and a second fixing member. A first elongated hole 81 is provided on the first pressure block 8, and a second elongated hole 91 is provided on the second pressure block 9. The length directions of both the first elongated hole 81 and the second elongated hole 91 are parallel to a second direction. A first fixing hole and a second fixing hole are provided on the cantilever 3. The first fixing member passes through the first elongated hole 81 and the first fixing hole to fix the first pressure block 8 to the cantilever 3. The second fixing member passes through the second elongated hole 91 and the second fixing hole to fix the second pressure block 9 to the cantilever 3.
[0060] The first fixing member can move within the first elongated hole 81, so the fixed position of the first pressure block 8 on the cantilever 3 can be adjusted along the second direction. The second fixing member can move within the second elongated hole 91, so the fixed position of the second pressure block 9 on the cantilever 3 can be adjusted along the second direction.
[0061] In one embodiment, such as Figure 3 and Figure 5 As shown, the slag-blocking device also includes a slide rail 10, which is mounted on the base 1. The end of the cantilever 3 furthest from the connecting rod 4 is slidably mounted on the slide rail 10, and the length direction of the slide rail 10 is parallel to the first direction. The cantilever 3 sliding on the slide rail 10 improves the stability of its movement along the second direction. The fact that the end of the cantilever 3 furthest from the connecting rod 4 is slidably mounted on the slide rail 10 ensures that the slide rail 10 and the drive unit 2 are located at the same end of the cantilever 3, thus preventing interference between the slide rail 10 and the drive unit 2 and other external components.
[0062] In this embodiment, the drive unit 2 can be a rodless cylinder.
[0063] Furthermore, this application also provides a laser processing device, which includes a slag-blocking device. The specific structure of the slag-blocking device is as described in the above embodiments. Since the laser processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.
[0064] In one embodiment, such as Figures 1 to 3 As shown, the laser processing equipment also includes a bed 20, a chuck 30, a laser head 40, and a floating support device 50. Both the chuck 30 and the laser head 40 are mounted on the bed 20. The chuck 30 is used to clamp the tube 60 and rotate it. The laser head 40 emits a laser beam to laser-cut the tube 60 held by the chuck 30. The floating support device 50 is connected to the bed 20 and supports the tube 60 extending out of the chuck 30. A base 1 is mounted on the floating support device 50 so that the drive unit 2, via the cantilever 3 and connecting rod 4, drives the slag-blocking component 5 to move along a first direction, extending into the tube 60 to block slag.
[0065] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
