Description

Technical Field

[0001] This application relates to the field of wire mesh welding technology, and more particularly to a planar metal wire mesh welding apparatus. Background Technology

[0002] Flat metal wire mesh, with its smooth surface and regular mesh structure, is widely used in many fields such as building reinforcement, protective fencing, and filtration, making it an indispensable basic material in modern industry and daily life. To ensure the stable and reliable functioning of flat metal wire mesh, the nodes of the woven mesh need to be welded to form a strong connection between the wires, thereby enhancing the overall structural strength and stability of the wire mesh.

[0003] Currently, planar metal wire mesh is usually made by hand weaving. Multiple steel wires are arranged in parallel at equal intervals in one direction to form a basic row of steel wires. Then, more steel wires are taken and attached to the previously arranged row of steel wires, and arranged in a staggered manner to intersect with the first row of steel wires to form a square, thus weaving a metal wire mesh. However, this type of wire mesh, which is woven solely by the physical contact between steel wires, is prone to welding point position deviations when placed under a welding device for welding operations. It is also difficult to ensure that the dimensions between adjacent steel wires are completely accurate and consistent. These problems will adversely affect the overall structural strength of the metal wire mesh. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a planar metal wire mesh welding device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides a planar metal wire mesh welding device, including: a welding table; a movable welding unit disposed above the welding table; and further including: a first limiting groove formed on the top of the welding table; a second limiting groove formed between the bottom of the first limiting groove and the bottom of the welding table; a base plate connected to the inner wall of the second limiting groove, wherein a plurality of first connecting plates and second connecting plates are fixedly connected to the top of the base plate, the first connecting plates extending laterally and the second connecting plates extending longitudinally, and the two are staggered to form a grid-like frame, and an independent welding node area is formed between each pair of adjacent first connecting plates and each pair of adjacent staggered second connecting plates, and a plurality of equidistantly distributed first wire grooves are formed between the top of each first connecting plate and the top of the base plate, and a plurality of equidistantly distributed second wire grooves are formed between the top of each second connecting plate and the top of the base plate.

[0006] In some implementations, the welding unit includes a concave frame fixedly connected to the top of the welding table. A first driving unit is installed on one side of the concave frame. The output end of the first driving unit is connected to a threaded rod rotatably disposed between the side walls of the concave frame. A slider is threadedly connected to the surface of the threaded rod. A second driving unit is installed at the bottom of the slider. A horizontal mounting plate is fixedly connected to the output end of the second driving unit. Multiple welding heads that are equidistantly distributed and correspond to the welding node areas are installed at the bottom of the mounting plate.

[0007] In some implementations, an extension block is fixedly connected to the top center of the slider, and a guide rod fixedly connected between the two sides of the extension block is passed through the concave frame sidewalls.

[0008] In some implementation schemes, both the first limiting groove and the second limiting groove are planar square structures, wherein the inner wall side length of the first limiting groove is greater than the inner wall side length of the second limiting groove.

[0009] In some implementations, the base plate and the inner wall of the second limiting groove are slidably connected. A corresponding fixing plate is provided below the bottom of the welding table. Vertical support plates are fixedly connected to the corners of the fixing plate. The top of the vertical support plate is fixedly connected to the bottom of the welding table. A base plate is fixedly connected to the bottom of the vertical support plate. Multiple limiting springs are fixedly connected between the top of the fixing plate and the bottom of the base plate. A third driving part that is linked with the base plate is installed at the top center of the fixing plate.

[0010] In some implementation schemes, the linkage between the third driving unit and the base plate is magnetically driven, the third driving unit is an electromagnet, and the bottom surface of the base plate is made of iron.

[0011] In some implementations, when the third drive unit is de-energized and separates from the bottom of the base plate, the top of the base plate remains flush with the bottom of the first limiting groove.

[0012] In some implementations, when the third drive unit is energized and adsorbed onto the bottom of the base plate, the tops of the first and second connecting plates remain flush with the bottom of the welding station.

[0013] In some implementations, a discharge groove is provided on one side of the welding table, and a limiting plate is attached to the inner wall of the discharge groove. An L-shaped connecting plate is fixedly connected between the bottom of the limiting plate and the bottom of the base plate. A pushing groove is provided on the top of the welding table, which is aligned and connected to the bottom of the first limiting groove. A matching pushing plate is attached to the inner wall of the pushing groove.

[0014] In some implementations, a fourth drive unit is mounted on one side of the push plate, and an L-shaped support frame is fixedly connected between the surface of the fourth drive unit and one side of the fixed plate.

[0015] By adopting the above technical solution, this application has the following beneficial effects compared with the prior art: Through the coordinated design of the first limiting groove with the base plate, the first connecting plate, the second connecting plate, the first wire groove and the second wire groove, the wires can be precisely limited when welding the metal wire mesh, so that the transverse and longitudinal wires are neatly arranged in the preset position, which greatly improves the stability of the metal wire mesh during the welding process and effectively ensures the welding quality. The base plate and the inner wall of the second limiting groove are designed to slide. When the top of the first connecting plate and the second connecting plate on the top of the base plate are aligned with the bottom of the welding table, the metal wire mesh can be easily detached from the top of the first connecting plate and the second connecting plate and placed naturally in the bottom of the first limiting groove. Compared with forcibly removing the metal wire mesh directly from the wire groove of the first connecting plate and the second connecting plate, this design is more convenient and faster, effectively avoiding damage to the metal wire mesh caused by forced removal, and improving the efficiency of the entire production process. In addition, during this process, the limiting plate will not obstruct the bottom of the first limiting groove, and can be used with the pushing plate to smoothly push the metal wire mesh placed at the bottom of the first limiting groove out of the discharge groove, achieving rapid unloading.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] Example 1: As Figure 1 As shown, a planar metal wire mesh welding device includes a welding table 1 and a movable welding unit disposed above the welding table 1.

[0020] like Figure 1 As shown, the welding unit includes a concave frame 2 fixedly connected to the top of the welding table 1. A first drive unit 21 is installed on one side of the concave frame 2. The output end of the first drive unit 21 is connected to a threaded rod 22 rotatably disposed between the side walls of the concave frame 2. A slider 23 is threadedly connected to the surface of the threaded rod 22. An extension block 27 is fixedly connected to the top center of the slider 23. A guide rod 28 fixedly connected between the side walls of the concave frame 2 passes through the two sides of the extension block 27 to guide and stabilize the movement of the slider 23, ensuring that the slider 23 can only move linearly along the axial direction of the threaded rod 22. A second drive unit 24 is installed at the bottom of the slider 23. A horizontal mounting plate 25 is fixedly connected to the output end of the second drive unit 24. Multiple equally spaced welding heads 26 are installed at the bottom of the mounting plate 25.

[0021] During the welding operation, the pre-woven metal wire mesh is first placed on top of the welding table 1, with the metal wire mesh positioned below the welding unit. This ensures that the intersecting nodes of the metal wire mesh correspond to the positions of the welding heads 26. Then, the second drive unit 24, which uses a cylinder, is activated to move the mounting plate 25 downwards. This causes the multiple welding heads 26 at the bottom of the mounting plate 25 to contact the intersecting nodes of the metal wire mesh, and weld this row of nodes. Once this row of nodes is welded, the first drive unit 21, which uses a servo motor, is activated to rotate the threaded rod 22. Since the slider 23 is threadedly connected to the threaded rod 22 and constrained by the guide rod 28, the slider 23 moves linearly along the axial direction of the threaded rod 22, thereby moving the mounting plate 25 and the welding heads 26 at its bottom to another row of nodes of the metal wire mesh for welding. This cycle repeats, allowing the welding heads 26 to weld the intersecting nodes of the metal wire mesh sequentially from left to right.

[0022] In the actual weaving process of planar metal wire mesh, manual operation is usually adopted. The specific weaving steps are as follows: First, multiple steel wires are arranged in parallel at equal intervals in one direction to form a basic row of steel wires. Then, multiple steel wires are taken and attached to the previously arranged row of steel wires, and arranged in an alternating manner in a square pattern with the first row of steel wires to weave the metal wire mesh. However, it is difficult to ensure that the dimensions between adjacent steel wires are completely consistent in this manual weaving method.

[0023] To solve this problem, based on the above technical solutions, such as... Figure 2 As shown, it also includes a first limiting groove 11 opened on the top of the welding table 1, a second limiting groove 12 opened between the bottom of the first limiting groove 11 and the bottom of the welding table 1, and a base plate 3 connected to the inner wall of the second limiting groove 12. The first limiting groove 11 and the second limiting groove 12 are both planar square structures. The inner wall side length of the first limiting groove 11 is greater than the inner wall side length of the second limiting groove 12. The top of the base plate 3 is fixedly connected with multiple first connecting plates 31 and second connecting plates 32. The first connecting plates 31 extend horizontally, and the second connecting plates 32 extend vertically. The two are arranged alternately to form a grid-like frame. This can accurately construct the reference frame for the metal wire mesh weaving, strictly regulate the arrangement direction of the wires, and effectively avoid the problem of random wire direction and messy arrangement when weaving manually.

[0024] Each pair of adjacent first connecting plates 31 and each pair of adjacent staggered second connecting plates 32 form an independent welding node area. Multiple equidistant first wire grooves 33 are provided between the top of each first connecting plate 31 and the top of the base plate 3, and multiple equidistant second wire grooves 34 are provided between the top of each second connecting plate 32 and the top of the base plate 3. The first wire grooves 33 and the second wire grooves 34 can accurately limit the transverse and longitudinal wires respectively, ensuring that the wires are arranged at equal intervals in their respective directions. This fundamentally solves the problem that it is difficult to ensure the consistency of adjacent wire dimensions by manual weaving, resulting in high dimensional accuracy and stable quality of the woven metal wire mesh, providing a reliable guarantee for subsequent high-quality welding operations.

[0025] During the welding process, the grid-like frame formed by the first connecting plate 31 extending laterally and the second connecting plate 32 extending longitudinally can firmly frame the metal wire mesh, ensuring that the wires can only be neatly arranged in the predetermined horizontal and vertical directions. This effectively prevents the wires from shifting or shaking due to external forces or their own stress during welding. The first wire groove 33, which is equidistantly distributed between the top of the first connecting plate 31 and the top of the bottom plate 3, and the second wire groove 34, which is equidistantly distributed between the top of the second connecting plate 32 and the top of the bottom plate 3, can precisely hold the horizontal and vertical wires, further restricting the displacement of the wires in the direction perpendicular to their arrangement. This ensures that each wire is stably in the preset position, allowing the welding head 26 to accurately align with the intersecting nodes of the wires for welding. This greatly improves the accuracy and stability of the welding and guarantees the welding quality of the metal wire mesh.

[0026] Example 2: Figures 4-8 As shown, in order to facilitate the detachment of the welded metal wire mesh from the first wire groove 33 at the top of the first connecting plate 31 and the second wire groove 34 at the top of the second connecting plate 32, an improvement has been made based on the above embodiment 1. Unlike embodiment 1, the inner wall of the base plate 3 and the second limiting groove 12 are connected by a sliding connection. A corresponding fixing plate 4 is provided below the bottom of the welding table 1. Vertical support plates 41 are fixedly connected to the corners of the fixing plate 4. The top of the vertical support plate 41 is fixedly connected to the bottom of the welding table 1. A base plate 42 is fixedly connected to the bottom of the vertical support plate 41. Multiple limiting springs 43 are fixedly connected between the top of the fixing plate 4 and the bottom of the base plate 3. A third driving part 44 that is linked with the bottom of the base plate 3 is installed at the top center of the fixing plate 4. The linkage between the third driving part 44 and the base plate 3 is magnetically driven. The third driving part 44 is an electromagnet. The bottom surface of the base plate 3 is made of iron.

[0027] When the third drive unit 44 using an electromagnet is de-energized, the third drive unit 44 and the bottom of the base plate 3 no longer attract each other. At this time, under the support and limitation of the fixed plate 4 and the limiting spring 43, the top of the base plate 3 is flush with the bottom of the first limiting groove 11. At the same time, the first connecting plate 31 and the second connecting plate 32 at the top of the base plate 3 are located in the first limiting groove 11. When the metal wire mesh is woven and welded, the transverse wires can be embedded in the first wire groove 33 at the top of the first connecting plate 31, and the longitudinal wires can be embedded in the second wire groove 34 at the top of the second connecting plate 32. Through the cooperation of the first connecting plate 31 and the second connecting plate 32, the wires can be neatly arranged in the predetermined transverse and longitudinal directions, thereby greatly improving the stability of the metal wire mesh during the welding process and ensuring the welding quality.

[0028] After the metal wire mesh is welded, it needs to be detached from the first connecting plate 31 and the second connecting plate 32. At this time, the third drive unit 44 is powered on and quickly adsorbs onto the iron part at the bottom of the base plate 3. Due to the adsorption between the third drive unit 44 and the base plate 3, the base plate 3 will be subjected to a downward pulling force. The base plate 3 is slidably connected to the inner wall of the second limiting groove 12. Under the action of the downward pulling force, the base plate 3 will slide down along the inner wall of the second limiting groove 12 and eventually be located below the bottom of the welding table 1. As the base plate 3 slides down, the first connecting plate 31 and the second connecting plate 32 fixed on the top of the base plate 3 will also descend accordingly until the first connecting plate 3... The top of the first and second connecting plates 31 and 32 are flush with the bottom of the welding table 1. In this way, the welded wire mesh, which was originally held in place by the first and second connecting plates 31 and 32, loses its constraint. At this time, the wire mesh can easily detach from the first and second connecting plates 31 and 32 and will naturally fall into the bottom of the first limiting groove 11. Compared with forcibly removing the wire mesh directly from the wire groove of the first and second connecting plates 31 and 32, this design is more convenient and faster, avoids damage to the wire mesh caused by forced removal, and also improves the efficiency of the entire production process.

[0029] Example 3: Figure 5 and Figure 8As shown, based on the above embodiment 2, a further improvement is made. Unlike embodiment 2, a discharge groove 45 is provided on one side of the welding table 1. A limiting plate 46 is attached to the inner wall of the discharge groove 45. An L-shaped connecting plate 47 is fixedly connected between the bottom of the limiting plate 46 and the bottom of the base plate 3. A pushing groove 48 is provided on the top of the welding table 1, which is aligned and connected to the bottom of the first limiting groove 11. A matching pushing plate 49 is attached to the inner wall of the pushing groove 48. A fourth driving part 410 is installed on one side of the pushing plate 49. An L-shaped support frame 411 is fixedly connected between the surface of the fourth driving part 410 and one side of the fixing plate 4.

[0030] In the above technical solution, since the limiting plate 46 slides against the inner wall of the discharge trough 45 and is connected to the bottom of the base plate 3 through the L-shaped connecting plate 47, when the third driving unit 44 is energized and exerts an adsorption effect on the bottom of the base plate 3, the base plate 3 will slide down along the inner wall of the second limiting groove 12. During the downward movement of the base plate 3, the limiting plate 46 will be driven to move down along the inner wall of the discharge trough 45 simultaneously through the L-shaped connecting plate 47. The bottom of the first limiting groove 11 is no longer blocked by the limiting plate 46. At this time, the fourth driving unit 410 using a cylinder is activated, driving the push plate 49 to move in the push groove 48. The push plate 49 will directly act on the first limiting plate 46. The welded metal wire mesh at the bottom of trough 11 is smoothly pushed out from discharge trough 45, achieving rapid unloading. Compared with manual removal of the metal wire mesh, this design greatly improves unloading efficiency. Manual removal not only consumes more time and manpower, but may also damage the metal wire mesh due to uneven force or improper operation, affecting product quality. This design realizes an automatic, fast, and stable unloading process, which not only saves labor costs, but also ensures the accuracy and consistency of unloading action, effectively improving the automation level and production efficiency of the entire production process, and further ensuring the product quality of the metal wire mesh.
