They mainly evenly distribute high-temperature resistance wires in high-temperature resistant stainless steel seamless pipes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. This structure is not only advanced and has high thermal efficiency, but also generates heat evenly. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal pipe through the crystalline magnesium oxide powder, and then is transferred to the heated part or the air to achieve the purpose of heating. It is the core component of the heater.

[0028] The following is combined with Figure 1-4The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment of a laser welding device, comprising a device body 1 and a welding mechanism 2. A protective block 3 is connected to the top of the device body 1 to protect the welding position and prevent strong light from leaking out. A bottom plate 5 is connected to the top of the protective block 3, and a side plate 6 is connected to the top of the bottom plate 5. The bottom plate 5 cooperates with the side plate 6 so that the residue can be removed at one time. A top opening 4 is also opened on the top of the protective block 3.

[0030] A bidirectional screw rod 12 is also connected to the inner side of the device body 1, and a threaded block 11 is connected to the center of the bidirectional screw rod 12. The bidirectional screw rod 12 cooperates with the threaded block 11, so that the fixed block 8 moves together toward the center direction. The inner side of the threaded block 11 is connected to the second magnet 15, and the inner side of the second magnet 15 is connected to the first magnet 14. The first magnet 14 cooperates with the second magnet 15 so that the insertion block 13 can be reset and aligned. The center of the first magnet 14 is connected to the insertion block 13, and the upper part of the insertion block 13 is connected to the limiting block 10. The other side of the limiting block 10 is connected to the linkage block 16, and the drive motor 7 is protected by the linkage block 16 to avoid damage. The left side of the linkage block 16 is connected to the drive motor 7, and the center of the drive motor 7 is connected to the fixed block 8. The center of the fixed block 8 is connected to the rubber block 9, which is auxiliary fixed by the rubber block 9 to ensure that the fixed block 8 is firmly fixed.

[0031] See the attached drawings in the specification Figure 1-4 The protective block 3 is connected to the device body 1 by hot melt connection. The center of the protective block 3 coincides with the center of the welding mechanism 2, and the center of the protective block 3 coincides with the center of the top opening 4. The size of the top opening 4 is larger than the size of the welding mechanism 2. A movable plate is provided on the front side of the top opening 4. Through the cooperation of the protective block 3 and the top opening 4, the welding mechanism 2 can enter the center position for welding.

[0032] See the attached drawings in the specification Figure 1-4 The connection between the bottom plate 5 and the protective block 3 is a sliding connection, and the connection between the bottom plate 5 and the side plate 6 is a hot melt connection. The top parallel line of the side plate 6 is lower than the bottom parallel line of the fixed block 8. Through the cooperation between the bottom plate 5 and the protective block 3, the residue can be cleaned at one time while avoiding the residue from splashing.

[0033] See the attached drawings in the specification Figure 1-4 The driving motor 7 and the fixed block 8 are coaxial rotating structures. Rubber blocks 9 are symmetrically distributed on the inner side of the fixed block 8. The connection between the fixed block 8 and the linkage block 16 is a rotating connection. The driving motor 7 drives the fixed block 8 to rotate, thereby causing the stainless steel pipe to rotate and complete the welding work.

[0034] See the attached drawings in the specification Figure 1-4 The connection between the limit block 10 and the linkage block 16 is a hot-melt connection. The limit block 10 forms a rotating structure with the threaded block 11 through the insertion block 13. The connection between the threaded block 11 and the bidirectional screw rod 12 is a threaded connection. The limit block 10 cooperates with the insertion block 13 so that the limit block 10 can rotate, which facilitates the installation of the stainless steel pipe.

[0035] See the attached drawings in the specification Figure 1-4 A second magnet 15 is symmetrically distributed on the inner side of the threaded block 11. The second magnet 15 and the first magnet 14 are attracted to each other. The first magnet 14 is symmetrically distributed on both sides of the center of the insertion block 13. The first magnet 14 cooperates with the second magnet 15 to make the insertion block 13 centered, which facilitates the subsequent alignment of the stainless steel pipe.

[0036] Working principle: When in use, first, rotate the linkage block 16, which rotates through the insertion block 13 and the threaded block 11 below the limit block 10, and place the stainless steel pipe to be welded into the inside of the fixed block 8, and then reset the insertion block 13. When the insertion block 13 is reset, it drives the first magnet 14 to move until the first magnet 14 and the second magnet 15 are automatically adsorbed, so that the center of the insertion block 13 coincides with the center of the insertion block 13 on the other side, that is, the stainless steel pipe is in a coincident state at this time, and then turn on the switch of the bidirectional screw rod 12, so that it and the threaded block 11 have a threaded motion, so that the insertion block 13 moves toward the center together with the linkage block 16 above it, until the two stainless steel pipes are aligned and fit together;

[0037] As mentioned above, after fitting, turn on the switch of the welding mechanism 2 and start welding. During welding, turn on the switch of the drive motor 7 so that it drives the fixed block 8 to rotate, so that a circle of the stainless steel pipe can be welded. The slag generated during welding falls on the top of the bottom plate 5. After welding is completed, if the length of the stainless steel pipe is short, it can be directly taken out after the linkage block 16 is reset. If the length is long, move the stainless steel pipe toward the front side of the protective block 3, and press against the movable plate so that the hinge above the movable plate and the protective block 3 rotate. Lift the movable plate to take out the stainless steel pipe. After taking it out, the movable block automatically resets under the action of gravity. It should be noted that the welding mechanism 2 is basic information known to people in this field. It is existing technology and is very mature, so it will not be described here.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
