Description

Technical Field

[0001] The present application relates to the field of laser processing technology, and in particular to a slag blocking assembly, device and laser tube cutting equipment. Background Art

[0002] With the development of laser processing technology, the application of laser tube cutting equipment in the market is becoming more and more extensive.

[0003] When laser tube cutting equipment is used to cut a tube, molten metal splashes as high-pressure air is blown out. This splashing molten metal easily splashes onto the inner wall of the tube, where it forms slag after solidifying, increasing the roughness of the inner wall. Therefore, slag stops are often required to block the inner wall of the tube to prevent the molten metal from splashing onto it.

[0004] Currently, slag stops are typically installed at the motor's output. When laser tube cutting equipment is cutting a tube, the motor drives the slag stopper into the tube to prevent molten metal from splashing onto the tube's inner wall. However, each replacement of the slag stopper requires recalibrating the concentricity between the stopper and the tube, resulting in lower cutting efficiency. Utility Model Content

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

[0039] The embodiments of the present application provide a slag blocking assembly, a device and a laser tube cutting device, which are used to solve the technical problem of low cutting efficiency of the laser tube cutting device.

[0040] In the embodiments of this application, Figure 2 and Figure 3 As shown, the slag stop assembly 100 includes a slag stopper 1 and a positioning member 2. The slag stopper 1 has a slag stopper groove 11 disposed therein. The cross-section of the slag stopper 1 is an arcuate ring, and the first opening 12 of the slag stopper groove 11 is formed on the outer circumference of the slag stopper 1. The positioning member 2 is disposed at the end of the slag stopper 1 and is provided with a first positioning connection portion 21, which is configured to connect to a second positioning connection portion corresponding to the first positioning connection portion 21.

[0041] It can be understood that when a plane parallel to the center line of a pipe is used to cut the pipe, the portion with a longer arc length of the cross section after cutting has the same structure as the slag stopper 1 .

[0042] In this embodiment, the slag stopper 1 can be made from a solid rod, wherein the slag stopper 1 and the positioning member 2 can be connected in one piece.

[0043] like Figures 1 to 3 As shown, when using the slag stopper assembly 100, the slag stopper 1 is inserted into the tube 6 to be processed, so that the first opening 12 faces the laser head of the laser tube cutting device 300. While the laser head is emitting a laser beam to process the tube 6, the chuck 5 is rotated to rotate the tube 6 clamped by the chuck 5, thereby completing the processing of the tube 6.

[0044] The slag stopper 1 of the embodiment of the present application is provided with a slag stopper groove 11, and the first opening 12 of the slag stopper groove 11 is opened on the outer peripheral surface of the slag stopper 1, so that the metal melt generated by the laser processing of the tube 6 can enter the slag stopper groove 11 from the first opening 12, and the groove wall of the slag stopper groove 11 prevents the metal melt from splashing on the inner wall of the tube 6, thereby achieving the slag stopping effect; the cross-sectional shape of the slag stopper 1 is an arc ring, so that the slag stopper 1 can be extended into the tube 6 to be processed to stop the slag, thereby achieving a better slag stopping effect; the positioning member 2 is provided at the end of the slag stopper 1, and the positioning member 2 is provided with a first positioning connection portion 21, and the first positioning The connecting portion 21 is used to connect to the second positioning connecting portion corresponding to the first positioning connecting portion 21, so that the positioning member 2 can be installed on the second positioning connecting portion through the first positioning connecting portion 21; the positioning member 2 can also be positioned in the process of connecting the first positioning connecting portion 21 with the second positioning connecting portion; therefore, after the slag stop assembly 100 is disassembled and replaced, the slag stop member 1 has been indirectly positioned through the first positioning connecting portion 21, and there is no need to re-debug and position the slag stop member 1, thereby improving the disassembly and replacement efficiency of the slag stop assembly 100, and further improving the efficiency of processing the pipe 6 of the laser tube cutting equipment 300.

[0045] In one embodiment, if Figure 3 As shown, the slag stop groove 11 further defines a second opening 13, which is located at an end of the slag stop member 1 away from the positioning member 2, and allows the jet airflow to flow out through the second opening 13. This prevents the jet airflow from becoming turbulent within the slag stop groove 11, causing the jet airflow to flow out of the first opening 12, causing the molten metal carried by the jet airflow to splash outside the slag stop groove 11, thereby reducing the slag blocking effect of the slag stop assembly 100.

[0046] In one embodiment, if Figure 3 As shown, the width L of the first opening 12 and the inner diameter R of the slag stopper 1 satisfy the following relationship:

[0047] L=M*R; where M ranges from 1.428 to 1.732.

[0048] When the width of the first opening 12 satisfies the above relationship, the slag blocking member 1 has a better slag blocking effect.

[0049] In one embodiment, if Figure 3 As shown, when R ≥ 6 mm, it satisfies:

[0050] L=M*R; where M ranges from 1.428 to 1.732;

[0051] When 4mm≤R<6mm, the following conditions are met:

[0052] L=8mm.

[0053] When the width of the first opening 12 satisfies the above relationship, the slag blocking member 1 has a better slag blocking effect.

[0054] In another optional embodiment, the width L of the first opening 12 is 5 mm-11 mm, so as to improve the slag blocking effect of the slag blocking member 1 .

[0055] In one embodiment, the first positioning connection portion is an internally threaded hole provided in the positioning member 2. In this case, the second positioning connection portion is an externally threaded hole corresponding to the first positioning connection portion. This allows the positioning member 2 to be positioned during the process of threadedly connecting the first and second positioning connection portions, thereby improving the concentricity between the slag stopper 1 and the pipe 6 to be processed, and facilitating the insertion of the slag stopper 1 into the pipe 6 to be processed. This also improves the efficiency of disassembly and replacement of the slag stopper assembly 100.

[0056] In another alternative embodiment, if Figure 2 and Figure 3 As shown, the first locating connection portion 21 is disposed at the end of the positioning member 2 away from the slag stopper 1. The outer circumference of the first locating connection portion 21 is provided with external threads. Meanwhile, the second locating connection portion is an internal thread corresponding to the first locating connection portion 21. This allows the positioning member 2 to be positioned during the threaded connection between the first locating connection portion 21 and the second locating connection portion, thereby improving the concentricity between the slag stopper 1 and the pipe 6 to be processed, and facilitating the insertion of the slag stopper 1 into the pipe 6 to be processed. This also improves the efficiency of disassembly and replacement of the slag stopper assembly 100.

[0057] In this embodiment, when the length of the slag stopper 1 needs to be increased according to actual needs, the length of the first positioning connection portion 21 can also be increased accordingly to improve the concentricity between the slag stopper 1 and the pipe 6 to be processed.

[0058] In one embodiment, if Figure 3As shown, a force-applying notch 22 is provided on the outer circumference of the positioning member 2. The force-applying notch 22 facilitates the user to apply force with a hand or a wrench, thereby facilitating the user to apply force on the positioning member 2 to connect the first positioning connection portion 21 with the second positioning connection portion.

[0059] In this embodiment, a wrench can be clamped in the force-applying notch 22 , so that the positioning member 2 can be rotated by the wrench, thereby connecting the first positioning connection portion 21 with the second positioning connection portion.

[0060] In one embodiment, if Figure 2 and Figure 3 As shown, the length of the slag retaining groove 11 is 50 mm to 100 mm, which can be applied to most pipe 6 processing, thereby improving the applicability of the slag retaining assembly 100 .

[0061] In addition, if Figure 2 and Figure 3 As shown, the embodiment of the present application also provides a slag stopping device 200, which includes a mounting member 3, a driving unit 4 and a slag stopping assembly 100; a second positioning connection portion is provided at one end of the mounting member 3, and the first positioning connection portion 21 is connected to the second positioning connection portion; an end of the mounting member 3 away from the second positioning connection portion is provided at the output end of the driving unit 4, and the driving unit 4 is used to drive the mounting member 3 to move along the center line of the slag stopping groove 11; the specific structure of the slag stopping assembly 100 refers to the above embodiment. Since the slag stopping device 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0062] In this embodiment, the driving unit 4 is used to drive the mounting member 3 to move along the center line of the slag retaining groove 11, so that the slag retaining member 1 can be extended into or out of the pipe to be processed 6. The mounting member 3 can also be extended into the pipe to be processed 6 to increase the depth of the slag retaining member 1 extending into the pipe to be processed 6.

[0063] In one embodiment, if Figure 2 As shown, the mounting member 3 may be a rod-shaped member.

[0064] In addition, if Figure 1 As shown, the embodiment of the present application also provides a laser tube cutting device 300, which includes a slag blocking device 200. The specific structure of the slag blocking device 200 refers to the above embodiment. Since the laser tube cutting device 300 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.
