Description

Technical Field

[0001] This utility model belongs to the field of laser welding technology, and specifically refers to a combined welding structure. Background Technology

[0002] PE material, especially PE pipes, is widely used in the sanitary ware industry.

[0003] In existing products, a connector is typically attached to one or both ends of the PE pipe to enable its wide applicability. Currently, the connection between the connector and the PE pipe is usually achieved using laser welding. However, existing welding processes involve fixing the laser head in one place and rotating the workpiece during welding to achieve a full circle. This welding method is inefficient and unsuitable for welding non-rotating surfaces. Utility Model Content

[0004] The main objective of this invention is to provide a combined welding structure that solves the problems existing in the prior art, improves welding efficiency, and has a wider range of applications.

[0005] To achieve the above objectives, the solution of this utility model is: A modular welding structure includes a relatively fixed workpiece to be welded and a plurality of laser heads spaced apart around a fusion line of the workpiece; the workpiece includes a first part and a second part; the end of the second part is inserted into the end of the first part, and a fusion line is pre-set on the periphery of the end of the first part; the laser heads are relatively fixed to the workpiece, and their emitting ends point towards the fusion line of the workpiece; all the laser heads are combined to cover the complete fusion line.

[0006] The first part is a polyethylene pipe, and the second part is a connector.

[0007] The laser heads are arranged at equal angular intervals with the center of the molten line as the midpoint.

[0008] The workpiece is fixed between the laser heads by a bracket, and the bracket does not obstruct the molten line.

[0009] After adopting the above technical solution, the present invention has the following technical effects: This invention combines multiple laser heads to achieve laser welding of a first part and a second part. The welding is performed simultaneously by multiple laser heads, which greatly improves production efficiency. Furthermore, during the welding process, both the workpiece and the laser head are in a fixed state and do not need to rotate. This means that the welding process is no longer limited to rotating bodies. It is only necessary to ensure that the laser beam after the laser head combination can cover the entire molten line to be welded. Attached Figure Description

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] refer to Figure 1 , 2 As shown, this utility model discloses a combined welding structure, including a workpiece 1 to be welded that is relatively fixed (i.e. no longer rotating), and a plurality of laser heads 2 arranged at intervals around the melting line 10 of the workpiece 1. The workpiece 1 includes a first part 11 and a second part 12; the end of the second part 12 is inserted into the end of the first part 11, and the end circumferential surface of the first part 11 is provided with a fusion line 10. The laser head 2 is fixed relative to the workpiece 1, and its emitting end is pointed towards the melting line 10 of the workpiece 1; All laser heads 2 are combined to cover the complete molten line 10.

[0015] Through the above scheme, this utility model combines multiple laser heads 2 together to achieve laser welding of the first part 11 and the second part 12. The welding is performed simultaneously by multiple laser heads 2, which greatly improves the production efficiency. Furthermore, during the welding process, both the workpiece 1 and the laser head 2 are in a fixed state and do not need to rotate, so that the welding process is no longer limited to rotating bodies. It is only necessary to ensure that the laser beam after the laser heads 1 are combined can cover the entire molten line 10 to be welded.

[0016] The following are specific embodiments of the present invention.

[0017] The first part 11 is a PE pipe (polyethylene pipe), and the second part 12 is a connector.

[0018] When the workpiece 1 to be welded is a rotating body, or the fusion line 10 is annular, the laser head 2 is set at equal angular intervals with the center of the fusion line 10 as the midpoint.

[0019] The aforementioned workpiece 1 is fixed between the laser heads 2 by a bracket, and the bracket does not obstruct the molten line 10.

[0020] The laser head 2 mentioned above refers to a laser emitter or laser emitting device used in the industry to achieve laser welding.

[0021] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
