Abstract
Description
Technical Field
[0001] The utility model relates to the field of welding strength testing tools, in particular to a wire mesh welding strength testing tool. Background Art
[0002] The intersection of the horizontal and vertical wires of the wire mesh product needs to be welded with a welding machine, and its welding strength directly affects the quality of the mesh. Therefore, each time the mesh is welded, it is necessary to detect the welding strength of the intersection of the horizontal and vertical wires. However, the existing torque wrench cannot be used directly to detect the welding strength of the mesh due to the lack of a fulcrum at the welding position. Therefore, it is urgent to design a wire mesh welding strength detection tooling, which plays the role of connecting the intersection of the horizontal and vertical wires of the mesh and the torque wrench, so as to facilitate the detection of welding strength by the torque wrench. According to the minimum welding strength requirements, the torque wrench is qualified if the data detected by the torque wrench is greater than the set requirements. If the detection does not meet the requirements, the resistance welding parameters need to be corrected. Utility Model Content

[0005] Specifically, the inner diameter of the groove is slightly larger than the diameter of the vertical wire of the mesh.
[0006] Preferably, the welding strength detection tool is a centrally symmetrical structure with the connecting hole as the center.
[0007] In a specific improvement, the connecting hole is a rectangular hole, which matches the size of the torque wrench connecting rod.

[0019] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.
[0020] Example 1: Please refer to Figures 1 - 4 A wire mesh welding strength testing tool comprises a middle part connected to a torque wrench and a hook-shaped part extending outward, wherein the middle part is provided with a rectangular connecting hole 4 matching the size of a torque wrench connecting rod 3, and the hook-shaped part is composed of two parallel hook heads 8, and a groove 5 matching the size of a mesh vertical wire 1 is formed between the two hook heads 8, and the arc surface formed by the hook head is used to hook the mesh horizontal wire 2; the arc surface (C surface) where the groove 5 is located is at an angle of 75° with the lower surface (D surface) of the middle part. The inner diameter (R2) of the groove is slightly larger than the diameter (R1) of the mesh vertical wire.
[0021] Example 2:Figure 1 and Figure 5 As shown in Figure 5 , a welding strength detection tooling for wire mesh sheets, the welding strength detection tooling has a central symmetry structure centered on the connection hole, and the distance between the center line of the connection hole 4 and the center line of the horizontal wire of the mesh sheet (the straight-line distance between line A and line B) is set to 20 ± 0.2 mm.
[0022] Embodiment 3
[0023] For the horizontal wires 2 and vertical wires 1 of wire mesh sheets with different diameters, the welding strength is determined by the torque of the torque wrench. Table 1 lists the minimum welding requirements for wire mesh sheets with common wire diameters. If the data detected by the torque wrench meets the detection requirements, it is considered qualified; if the detection fails to meet the requirements, the resistance welding parameters need to be corrected. It should be noted that Table 1 only lists some wire mesh sheets with wire diameters for example purposes.
[0024] Table 1
[0025] Serial number Wire diameter (mm) Minimum welding strength (N×m) 1 6 68.6 2 7.6 117.6
[0026] During use, first insert the connecting rod 3 of the torque wrench into the connection hole 4, then insert this tooling into the welding position, hook the hook head onto the horizontal wire and vertical wire of the mesh sheet. Immediately press the torque wrench to a certain angle. After hearing a "click" sound, start reading the torque value, and then compare it with the minimum welding strength in Table 1. If the data detected by the torque wrench meets the detection requirements, it is considered qualified; if the detection fails to meet the requirements, the resistance welding parameters need to be corrected.
