Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, specifically to a specialized wire feeding nozzle. Background Technology

[0002] With the development of science and technology, my country's manufacturing industry is facing a transformation towards high-end and intelligent manufacturing. As a basic processing technology, laser technology is increasingly penetrating all aspects of industrial production. Laser welding is a precision melting welding technology that uses a high-energy-density laser beam as a heat source to achieve efficient connection by focusing the laser beam to melt the material.

[0003] In welding technology, welding wire is an essential consumable. During the welding process, the welding wire needs to be fed into the weld pool. In order to ensure stable welding, wire feeding nozzles have emerged on the market, which can stably install and fix the welding wire, and have become one of the key components of welding equipment.

[0004] While existing wire feeding nozzles can feed wire stably, traditional coaxial wire feeding welding nozzles and wire feeding components are separate, with the wire feeding component installed on the side of the welding nozzle. This results in a larger structure at the nozzle, making it unusable when welding some narrow workpieces. Furthermore, the wire feeding component lacks a protective structure, making the wire feeding port prone to clogging by slag, which cannot meet processing requirements and is detrimental to improving product competitiveness. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a professional wire feeding nozzle, which solves the problem of the welding nozzle and wire feeding component being set separately in the prior art, resulting in large size and easy wire blockage due to slag backflow.

[0006] This utility model discloses a professional wire feeding nozzle, including a nozzle body. A wire feeding section is provided at the lower end of the nozzle body. The wire feeding section is provided with a laser channel, a wire feeding channel and a protective air channel. A wire outlet is provided at the lower end of the wire feeding channel. One end of the protective air channel is connected to protective gas, and the other end of the protective air channel is provided with an air knife facing the wire outlet. The protective air channel can form a protective air curtain below the wire outlet to protect the wire outlet by connecting to the protective gas.

[0007] The present invention is further improved in that the wire feeding part is a wire feeding mounting component fixedly installed at the lower end of the nozzle body, and the upper end surface of the wire feeding mounting component is provided with a mounting part, which is detachably connected to the nozzle body.

[0008] This utility model is further improved by providing a lower mounting screw hole in the mounting part, and an upper mounting screw hole at the corresponding position of the nozzle body and the lower mounting screw hole. A fixing screw is provided in the lower mounting screw hole, and the upper end of the fixing screw passes through the lower mounting screw hole and is threadedly connected to the upper mounting screw hole.

[0009] This utility model is further improved by providing a positioning cylinder extending upward at the corresponding position at the upper end of the laser channel in the mounting part, and a positioning port that cooperates with the positioning cylinder is provided inside the nozzle body. The positioning cylinder can cooperate with the positioning port to improve the positional stability between the wire feeding mounting part and the nozzle body.

[0010] This utility model is further improved by providing a positioning pin in the mounting part and a positioning pin hole in the nozzle body that cooperates with the positioning pin, with the positioning pin set in the positioning pin hole.

[0011] This utility model is further improved by setting the wire feeding channel at an angle from top to bottom towards the laser channel.

[0012] This invention is further improved by placing a protective gas channel between the laser channel and the wire feeding channel.

[0013] This utility model is further improved by providing a protective gas inlet on the nozzle body and an air knife channel that cooperates with the protective gas inlet inside the nozzle body, with an air outlet that cooperates with the protective gas channel at the lower end of the air knife channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a professional wire feeding nozzle. Its structure can effectively solve the problems of the welding nozzle and wire feeding part being set separately in the prior art, resulting in large size and easy wire blockage due to slag backflow. By setting the wire feeding part below the nozzle body, the laser channel and wire feeding channel are integrated in the wire feeding part, effectively reducing the size of the welding nozzle. Furthermore, through the setting of the protective air channel, the air channel outlet blows out a high-speed airflow to form a protective air curtain to efficiently protect the wire outlet, which can effectively avoid wire blockage due to slag backflow.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, this utility model discloses a professional wire feeding nozzle, including a nozzle body 1. The lower end of the nozzle body 1 is provided with a wire feeding section, which is provided with a laser channel 21, a wire feeding channel 22 and a protective air channel 23. The lower end of the wire feeding channel 22 is provided with a wire outlet 220. One end of the protective air channel 23 is connected to protective gas, and the other end of the protective air channel 23 is provided with an air knife 230, which faces the wire outlet 220. The protective air channel 23 can form a protective air curtain below the wire outlet 220 to protect the wire outlet 220 by connecting to the protective gas.

[0021] By placing the wire feeding section below the nozzle body 1, and integrating the laser channel 21 and the wire feeding channel 22 in the wire feeding section, the volume of the welding nozzle is effectively reduced. Furthermore, by setting up the protective air channel 23, a high-speed airflow is blown out of the air channel opening to form a protective air curtain to efficiently protect the wire outlet 220, which can effectively prevent the wire from being blocked by back slag, meet the processing requirements, and help improve the competitiveness of the product.

[0022] Welding wire 3 is installed in the wire feeding channel 22.

[0023] The air knife edge 230 is flush with the lower end face of the wire outlet 220, and the width of the air knife edge 230 is greater than the width of the wire outlet 220.

[0024] The wire feeding part is a wire feeding mounting part 2 fixedly installed at the lower end of the nozzle body 1. The upper end surface of the wire feeding mounting part 2 is provided with a mounting part, which is detachably connected to the nozzle body 1.

[0025] By separating the wire feeding mounting component 2 from the nozzle body 1, the processing difficulty can be effectively reduced, production costs can be controlled, and the yield rate can be guaranteed.

[0026] The mounting section is provided with a lower mounting screw hole 201. The nozzle body 1 is provided with an upper mounting screw hole 101 at the corresponding position of the lower mounting screw hole 201. A fixing screw 4 is provided in the lower mounting screw hole 201. The upper end of the fixing screw 4 passes through the lower mounting screw hole 201 and is threadedly connected to the upper mounting screw hole 101.

[0027] The combination of fixing screw 4, upper mounting screw hole 101 and lower mounting screw hole 201 can effectively improve the disassembly and assembly efficiency.

[0028] The mounting part has a positioning cylinder 202 extending upward at the corresponding position at the upper end of the laser channel 21, and the nozzle body 1 has a positioning port 102 that cooperates with the positioning cylinder 202.

[0029] By setting the positioning cylinder 202, it can cooperate with the positioning port 102 to improve the stability of the position between the wire feeding mounting part 2 and the nozzle body 1.

[0030] The mounting section is equipped with a positioning pin, and the nozzle body 1 is provided with a positioning pin hole 103 that mates with the positioning pin. The positioning pin is located in the positioning pin hole 103.

[0031] The positional stability between the wire feeding mounting component 2 and the nozzle body 1 can be further improved by the cooperation of the positioning pin and the positioning pin hole 103.

[0032] The wire feeding channel 22 is inclined from top to bottom towards the laser channel 21. This inclination allows the welding wire 3 to be accurately fed into the welding pool.

[0033] The protective air duct 23 is set between the laser channel 21 and the wire feeding channel 22. This setting can effectively utilize the inclined setting of the wire feeding channel 22 to create a clearance space between the laser channel 21 and the wire feeding channel 22. The protective air duct 23 is set in the clearance space, which can control the volume of the wire feeding mounting component 2 while efficiently protecting the wire outlet 220.

[0034] The nozzle body 1 is provided with a protective gas inlet interface 5, and the nozzle body 1 is provided with an air knife channel that cooperates with the protective gas inlet interface 5. The lower end of the air knife channel is provided with an air outlet 104 that cooperates with the protective air channel 23.

[0035] By connecting external protective gas through the protective gas inlet port 5, the volume of the wire feeding mounting component 2 can be further controlled, thus preventing the protective gas inlet port 5 from increasing the volume of the wire feeding mounting component 2.

[0036] As can be seen from the above, the beneficial effects of this utility model are: it can effectively solve the problem of the welding nozzle and wire feeder being set separately in the prior art, resulting in large size and easy wire blockage due to slag backflow. By setting the wire feeder below the nozzle body 1, the laser channel 21 and wire feeder 22 are integrated in the wire feeder, effectively reducing the size of the welding nozzle. Furthermore, through the setting of the protective air channel 23, the air channel outlet blows out a high-speed airflow to form a protective air curtain to efficiently protect the wire outlet 220, which can effectively avoid wire blockage due to slag backflow, meet processing requirements, and help improve the competitiveness of the product.

[0037] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
