Technical Field

[0001] The utility model relates to the technical field of metal mesh welding, in particular to a metal mesh welding tool. Background Art

[0002] The production of pet cages is to install multiple wire meshes together. In the process of making the wire meshes, the wires need to be placed horizontally and vertically in an alternating manner. Then, welding equipment is used to weld the contact positions of the horizontal wires and the vertical wires to form a mesh structure. To make a wire mesh, each contact position needs to be welded. Normally, the horizontal wires are arranged at equal intervals, and then the vertical wires are arranged at equal intervals. When welding, it is necessary to ensure that the horizontal wires and the vertical wires do not move relative to each other to ensure that the welding is firm. In the existing production process, there is a lack of tooling specifically for metal mesh welding. Utility Model Content

[0007] Furthermore, plug-in plates are fixed on both sides of the center line in the width direction of the frame, an plug-in gap is formed between the plug-in plate and the frame, and both ends of the pressing sheet are respectively inserted into the plug-in gaps on both sides.

[0008] Furthermore, the clamping member is configured as a U-shaped clamping member, the middle of the U-shaped clamping member is embedded in the crossbeam, and the clamping bolt is screwed into the U-shaped clamping member to clamp the frame placed on the crossbeam.

[0009] Furthermore, two threaded holes are provided on the same side of the U-shaped clamping piece, and the threaded holes are used to fix the clamping bolts.

[0010] Furthermore, the crossbeam has a supporting surface and a limiting surface perpendicular to the supporting surface, the supporting surface is used to support the frame, and the limiting surface is used to limit the edge of the frame.

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] See also Figure 1 and Figure 2, a schematic structural diagram of a metal mesh welding tool in an embodiment of the utility model is shown, comprising a base frame 100, two parallel beam assemblies 200, and a welding jig 300; the two parallel beam assemblies 200 are detachably fixed to the base frame 100, each beam assembly 200 comprises a beam 210 fixed to the base frame 100, a clamping member 220 fixed to the beam 210, and a clamping bolt 230 threadedly connected to the clamping member 220; the welding jig 300 comprises a frame 310 clamped to the beam assembly 200, a plurality of transverse limiting rods 320 fixed to the frame 310, and a plurality of longitudinal limiting rods 330 fixed to the frame 310, a plurality of accommodating grooves a for accommodating metal wires are evenly spaced on the transverse limiting rods 320 and the longitudinal limiting rods 330, a pressing sheet 311 is provided on the frame 310, and the pressing sheet 311 is used to prevent the metal wires from escaping from the accommodating grooves a. In one embodiment, the transverse limiting rod 320 and the longitudinal limiting rod 330 are arranged in a cross-shaped manner. Further, the pressing sheet 311 is provided with a piece that spans the frame 310 and is parallel to the transverse limiting rod 320 or the longitudinal limiting rod 330. In this embodiment, a mode parallel to the transverse limiting rod 320 is shown.

[0028] See also Figure 4 and Figure 5 During installation, the welding jig 300 is placed between two parallel beam assemblies 200, and the clamping bolts 230 are adjusted to fix the frame 310 of the welding jig 300 to the beam assembly 200 to prevent the welding jig 300 from being displaced. Then, the longitudinal metal wires are placed first, that is, a plurality of metal wires are placed inside the receiving groove a of the transverse limiting rod 320. After the placement is completed, the transverse metal wires are placed, that is, a plurality of metal wires are placed inside the receiving groove a of the longitudinal limiting rod 330, and the pressing sheet 311 is fixed to the frame 310. The pressing sheet 311 spans the frame 310 to prevent the metal wire 10 from escaping from the receiving groove a.

[0029] The above-mentioned metal mesh welding tooling is provided with two crossbeam assemblies 200 for fixing the welding jig 300, so as to fundamentally avoid the possibility that the welding jig 300 is displaced during the welding process and affects the welding quality. Furthermore, the welding jig 300 includes a frame 310, a transverse limiting rod 320 and a longitudinal limiting rod 330. The equally spaced receiving grooves a provided on the transverse limiting rod 320 and the longitudinal limiting rod 330 are utilized to ensure that the placed metal wires are placed at equal intervals, thereby ensuring that the mesh is uniform after the metal mesh is welded. In addition, when the transverse metal wire and the longitudinal metal wire are in contact with each other during welding, the welding head of the welding machine may stick to the metal wire, and the welding head may pull up the metal wire 10, resulting in unnecessary relative displacement between the transverse iron wire and the longitudinal iron wire. As an example, see Figure 5In this embodiment, a pressing sheet 311 is provided on the frame 310, and the pressing sheet 311 spans the frame 310 to prevent the metal wire 10 from escaping from the receiving groove a. It should be noted that Figure 5 The middle pressure plate 311 is located at the top layer and can prevent the metal wire from escaping from the receiving groove a. Since the horizontal metal wires are at the top and the metal wires are staggered with each other, the pressure plate 311 provided in this embodiment can press down and limit the part of the metal wires located at the top from the end, thereby limiting the position of the metal wires at the bottom, thus avoiding the displacement of the metal wires above or below due to adhesion to a certain extent, thereby improving product quality and production stability.

[0030] In one embodiment, an insertion plate 312 is fixed on both sides of the midline of the frame 310 in the length direction, an insertion gap is formed between the insertion plate 312 and the frame 310, and both ends of the pressing sheet 311 are respectively inserted into the insertion gaps on both sides.

[0031] In another embodiment, an insertion plate 312 is fixed on both sides of the center line of the frame 310 in the width direction, an insertion gap is formed between the insertion plate 312 and the frame 310, and both ends of the pressing piece 311 are respectively inserted into the insertion gaps on both sides.

[0032] It should be noted that the setting position of the pressing plate 311 can be determined according to the direction of the upper metal wire 10. If the longitudinal metal wire 10 is located above the transverse metal wire 10, which is the case shown in this embodiment, the longitudinal metal wire 10 located at the upper part needs to be pressed down to limit the position. On the contrary, if the transverse metal wire 10 is located above the longitudinal metal wire 10, the transverse metal wire 10 needs to be pressed down to limit the position. In this way, the pressing plate 311 can be set to limit the position of all the metal wires 10 to prevent the metal wires 10 from escaping from the receiving groove a during the welding process. In addition, the pressing plate 312 is used to insert the pressing plate 311. Since the pressing plate 311 is flexible, it can be slightly bent to insert the two ends of the pressing plate 311 into the insertion gap on both sides, which is convenient for removing or inserting the pressing plate 311.

[0033] See also Figure 2 In one embodiment, a plurality of fixing holes 110 are provided on the base frame 100, and the fixing holes 110 are used to fix with the cross beam 210 to adjust the distance between the two cross beam components 200. In this way, the welding of metal meshes of different specifications can be adapted. When welding a metal mesh of a smaller size, it is only necessary to adjust the distance between the two cross beam components 200, so that they are closer to each other, and vice versa, they are farther away from each other, thereby improving the scope of application and adjustment flexibility of the tooling.

[0034] See also Figure 6In one embodiment, the clamping member 220 is configured as a U-shaped clamping member, the middle of the U-shaped clamping member is embedded in the cross beam 210, and the clamping bolt 230 is screwed into the U-shaped clamping member to clamp the frame 310 placed on the cross beam 210. Further, in one embodiment, two threaded holes are opened on the same side of the U-shaped clamping member, and the threaded holes are used to fix the clamping bolt 230.

[0035] Continue to see Figure 6 In one embodiment, the crossbeam 210 has a support surface 211 and a limiting surface 212 perpendicular to the support surface 211. The support surface 211 is used to support the frame 310, and the limiting surface 212 is used to limit the edge of the frame 310. Figure 6 As shown, the cross section of the beam 210 is L-shaped, so that the mutually perpendicular limiting surface 212 and the supporting surface 211 can be utilized. Specifically, the limiting surface 212 is utilized to limit the edge of the frame 310, further improving the stability during the welding process.
