Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of welding rods and relates to a welding rod. Background Art
[0002] Before the welding rod is put into use, it is necessary to conduct a tensile test on the welding rod to obtain the pressure that the welding rod bears during use and whether the welding rod production inspection is qualified or not. When conducting a tensile test on the welding rod, the two sides of the welding rod are generally clamped and then pulled to both sides until it breaks. However, during the test, the existing welding rod is prone to breakage at the clamping point rather than in the middle of the welding rod, resulting in inaccurate tensile test results. Summary of the invention
[0003] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a welding rod, which solves the problem that during the test process, the existing welding rod is prone to break at the clamping point rather than in the middle of the welding rod, resulting in inaccurate results of the tensile test.
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A welding rod, characterized in that it includes a welding rod body, the upper and lower sides of the welding rod body are arc structures, the left and right sides of the welding rod body are plane structures, and cylindrical clamping blocks are provided on the front and rear sides of the welding rod body. The height of the welding rod body is equal to the diameter of the cylindrical clamping block, and the width of the welding rod body is smaller than the diameter of the cylindrical clamping block.
[0006] In the above welding rod, the welding rod body and the cylindrical clamping block are made of tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer material.
[0007] In the above welding rod, the welding rod body and the cylindrical clamping block are an integrated structure, which is cut from an injection-molded tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer cylinder.
[0008] In the above welding rod, the diameter of the cylindrical clamping block is 5 mm.
[0009] Compared with the prior art, the utility model has the following advantages:
[0010] When the clamping device drives the cylindrical clamping block to pull to both sides, the breaking point of the welding rod will be located in the middle of the welding rod body instead of breaking on the cylindrical clamping block, making the tensile test more accurate.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] like Figure 1 to Figure 2 As shown,
[0017] A welding rod, characterized in that it includes a welding rod body 2, the upper and lower sides of the welding rod body 2 are arc structures, the left and right sides of the welding rod body 2 are plane structures, and cylindrical clamping blocks 3 are provided on the front and rear sides of the welding rod body 2. The height of the welding rod body 2 is equal to the diameter of the cylindrical clamping block 3, and the width of the welding rod body 2 is smaller than the diameter of the cylindrical clamping block 3.
[0018] In this embodiment, the clamping devices on both sides clamp the cylindrical clamping blocks 3 on both sides. Since the width of the electrode body 2 is smaller than the diameter of the cylindrical clamping block 3, when the clamping device drives the cylindrical clamping block 3 to both sides, the breaking point of the electrode will be located in the middle of the electrode body 2, rather than breaking on the cylindrical clamping block 3, making the tensile test more accurate.
[0019] In this embodiment, the electrode body 2 and the cylindrical clamping block 3 are made of tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer material.
[0020] In this embodiment, the welding rod body 2 and the cylindrical clamping block 3 are an integrated structure, which is cut from a tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer cylinder that is injection molded. The entire welding rod is cut after injection molding, and no specific mold needs to be made, which is simple to make.
[0021] In this embodiment, the diameter of the cylindrical clamping block 3 is 5 mm.
[0022] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0023] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0024] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0025] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
