Description

Technical Field

[0001] This utility model belongs to the field of building mesh technology, specifically relating to an automatic welding machine for building mesh. Background Technology

[0002] Steel wire mesh is a commonly used building material in construction projects for crack prevention, reinforcement, and wall insulation. It is mainly made of steel wire or galvanized iron wire woven or welded. Its materials include high-carbon steel wire, low-carbon steel wire, and stainless steel wire, and the production processes cover ordinary weaving, embossed weaving, and spot welding.

[0003] In the production process of welded wire mesh for construction, it is often necessary to simultaneously arrange and weld the longitudinal and transverse steel wires. However, existing equipment can usually only feed the longitudinal wires in one direction through equally spaced longitudinal wire feeders. Then, the transverse wires are positioned manually. After the transverse and longitudinal wires cross perpendicularly, the intersection points of the transverse and longitudinal wires are spot welded and fixed one by one by the welding execution component. After the welding is completed, the transverse wires are cut off, and then the longitudinal wires are fed. Then, the new transverse wires are manually pulled and positioned again, and so on.

[0004] Existing construction metal mesh welding machines rely on manual wire laying for the horizontal wires, which is relatively inefficient. Furthermore, the accuracy and verticality of manual wire laying are poor, resulting in relatively low welding quality of the metal mesh. In addition, relying on manual wire laying is relatively dangerous, as improper operation can easily lead to burns from the welding components. Moreover, people who stay near the machine for a long time are likely to inhale the fumes generated during welding, causing health hazards. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide an automatic wire mesh welding machine for construction, solving the problems of existing construction metal mesh welding machines that rely on manual wire laying for the horizontal wires, resulting in relatively low efficiency, poor precision and verticality during manual wire laying, leading to relatively low welding quality of the metal mesh, and relatively high risks associated with manual wire laying, such as burns from welding components due to improper operation, and health hazards caused by inhaling welding fumes while continuously staying near the machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic welding machine for construction mesh, comprising a main support platform, a welding operation plate fixedly mounted on the upper side of the main support platform, vertical support plates fixedly mounted on the middle of both sides of the main support platform, a transverse electric guide rail fixedly mounted on the upper end of the vertical support plate, longitudinal wires arranged equidistantly and parallel on the upper side of the welding operation plate, a fixing plate fixedly mounted on one side of the main support platform below the vertical support plate, an electric wire feeding device fixedly mounted on the side of the fixing plate, a transverse wire wound and driven on the outer side of the electric wire feeding device, and an opening on the lower side of the side of the vertical support plate. A through-hole is provided, which is higher than the upper side of the welding operation plate. The horizontal wire passes through the through-hole and passes through the vertical support plate. Lateral electric guide rails are symmetrically fixed on both sides of the transverse electric guide rail. A second lateral electric slider is slidably provided on the lower side of each lateral electric guide rail. A second electric telescopic push rod is fixedly provided on the lower side of the second lateral electric slider. A functional connecting block is fixedly connected to the lower output end of the second electric telescopic push rod. A third electric hydraulic push rod is fixedly provided on the side of each functional connecting block that is close to each other.

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0038] like Figure 1 — Figure 6The diagram shows an automatic welding machine for construction mesh, comprising a main support platform 1. A welding operation plate 2 is fixedly mounted on the upper side of the main support platform 1. Vertical support plates 3 are fixedly mounted on the middle of both sides of the main support platform 1. A transverse electric guide rail 4 is fixedly mounted on the upper end of the vertical support plate 3. Longitudinal wires 12 are arranged equidistantly and parallel on the upper side of the welding operation plate 2. A fixing plate is fixedly mounted on one side of the main support platform 1 below the vertical support plate 3. An electric wire feeding device 19 is fixedly mounted on the side of the fixing plate. A transverse wire 20 is wound and driven around the outer side of the electric wire feeding device 19. A through hole 21 is opened on the lower side of the side of the vertical support plate 3. The through hole 21 is higher than the upper side of the welding operation plate 2, through which the transverse wire 20 passes. The guide hole 21 passes through the vertical support plate 3. Lateral electric guide rails 26 are symmetrically fixed on both sides of the transverse electric guide rail 4. A second lateral electric slider 27 is slidably mounted on the lower side of each lateral electric guide rail 26. A second electric telescopic push rod 28 is fixedly mounted on the lower side of the second lateral electric slider 27. A functional connecting block 29 is fixedly connected to the lower output end of the second electric telescopic push rod 28. A third electric hydraulic push rod 30 is fixedly mounted on the side of each functional connecting block 29 that is close to each other. A clamping block 31 is fixedly mounted on the output end of each third electric hydraulic push rod 30 that is close to each other. The clamping block 31 clamps and is mounted on both sides of the horizontal wire 20. This technical solution does not require manual wire laying and can automatically lower the wire after spot welding a single horizontal wire. A single horizontal wire arrangement increases the efficiency of horizontal wire arrangement and offers better precision and perpendicularity compared to manual wire arrangement, preventing a decrease in the welding quality of the metal mesh and avoiding the dangers of manual wire arrangement, such as inhaling welding fumes and causing health hazards. A first horizontal electric slider 5 is slidably mounted on the lower side of the horizontal electric guide rail 4. A first electric telescopic push rod 6 is fixedly mounted on the lower side of the first horizontal electric slider 5. A welding execution component 7 is fixedly mounted on the lower output end of the first electric telescopic push rod 6 for spot welding and fixing the longitudinal wire 12 and the horizontal wire 20. A first fixing block 8 is symmetrically fixedly mounted on the upper side of one side of the main support platform 1, and a first fixing block 8 is fixedly mounted on the lower side of the main support platform 1 corresponding to the first fixing block 8. Two fixed blocks 9, with guide shafts 10 rotatably mounted between the first fixed block 8 and the second fixed block 9. Longitudinal wire guide wheels 11 are fixedly mounted at equal intervals on the outer side of each guide shaft 10. Longitudinal wires 12 are guided and driven between the longitudinal wire guide wheels 11, for guiding the longitudinal wires 12 parallelly and at equal intervals to the upper side of the welding operation plate 2. A third fixed block 13 is symmetrically fixed on the side of the main support platform 1 away from the guide shafts 10. Drive rollers 14 are rotatably mounted between the third fixed blocks 13. A drive motor 15 is fixedly mounted on the side of one of the third fixed blocks 13, with the output end of the drive motor 15 passing through the third fixed block 13 and fixedly connected to the drive roller 14. Roller shaft connecting brackets 16 are fixedly mounted on both sides of the main support platform 1.Each of the roller connecting brackets 16 has a first electro-hydraulic push rod 17 fixedly mounted on its upper side. A shaft end block is fixedly mounted downwards at the output end of the first electro-hydraulic push rod 17. A pressure roller 18 is rotatably mounted between the shaft end blocks. The pressure roller 18 is pressed against the upper side of the drive roller 14. The traction end of the longitudinal wire 12 is passed parallel to each other between the drive roller 14 and the pressure roller 18. The first electro-hydraulic push rod 17 is activated, the pressure roller 18 is adjusted to press against the drive roller 14, and the drive motor 15 is activated. The drive roller 14 rotates away from the main support platform 1, thereby traction of the longitudinal wire 12. A transverse block 22 is fixedly mounted on the side of the vertical support plate 3 with a through hole 21 near the welding operation plate 2. A second electro-hydraulic push rod 23 is fixedly mounted on the lower side of the transverse block 22. A shearing pressure knife 24 is fixedly mounted on the lower output end of the second electro-hydraulic push rod 23. A shearing support platform 2 is fixedly mounted on the upper side of the main support platform 1, directly opposite the shearing pressure knife 24. 5. The shearing support table 25 is set close to the side of the welding operation plate 2. After welding, it automatically cuts the horizontal wire 20. The clamping blocks 31 are provided with pressure sensing motor plates on their adjacent sides. By setting pressure sensing electrodes, the clamping pressure on the horizontal wire 20 can be stably controlled. The lower side of the through hole 21 is provided with a steering wheel 32 corresponding to the horizontal wire 20. The horizontal wire 20 is connected to the steering wheel 32 by a turning transmission, which turns and guides the horizontal wire 20 to the through hole 21. The longitudinal wire guide... Wheel 11 includes a guide main wheel 111, which is slidably sleeved on the outside of the guide shaft 10. A side limiting sleeve 112 is fixedly provided on one side of each guide main wheel 111. A limiting fixing bolt 113 is threadedly connected to the outside of each side limiting sleeve 112. The limiting fixing bolt 113 penetrates the side limiting sleeve 112 and presses against the outer surface of the guide shaft 10. Tightening the limiting fixing bolt 113 allows adjustment of the spacing of the longitudinal wire guide wheels 11 as needed.

[0039] The working principle and usage process of this utility model are as follows: In use, the longitudinal wire feeder can be fixedly installed at equal intervals on the input side of the main support platform 1, that is, the side close to the first fixed block 8, through the shaft frame. The longitudinal wire feeder feeds out the longitudinal wires 12 at equal intervals and parallel to each other. After turning through the corresponding longitudinal wire guide wheels 11 on the lower and upper sides, the parallel longitudinal wires 12 pass through the upper side of the welding operation plate 2, and are used to guide the longitudinal wires 12 at equal intervals and parallel to the upper side of the welding operation plate 2. Initially, the traction end of the longitudinal wires 12 is passed parallel to each other between the drive roller 14 and the pressure roller 18. The first electric hydraulic push rod 17 is activated, the pressure roller 18 is adjusted to press the drive roller 14, and the drive motor 15 is activated. The drive roller 14 rotates to the side away from the main support platform 1, thereby being able to traction the longitudinal wires 12. When it is necessary to lay the horizontal wire 20, the horizontal wire 20 is pulled out from the electric wire feeding device 19, and then passes through the through hole 21 through the vertical support plate 3. The third electric hydraulic push rod 30 is activated, and the third electric hydraulic push rod 30 pushes the clamping block 31 to clamp the horizontal wire 20. Then, the second lateral electric slider 27 is activated, and the second lateral electric slider 27 slides towards the vertical support plate 3 away from the through hole 21. The clamping block 31 will simultaneously pull the horizontal wire 20, and the horizontal wire 20 passes through the upper side of the longitudinal wire 12 one by one. When the horizontal wire 20 approaches the other side of the vertical support plate 3, the second electric telescopic push rod 28 is activated. The second electric telescopic push rod 28 pushes down the functional connecting block 29, and the functional connecting block 29 drives the third electric hydraulic push rod 30 to move down. The third electric hydraulic push rod 30 passes through the clamping block 30. Block 31 moves the transverse wire 20 downwards, simultaneously activating the second electro-hydraulic push rod 23. The second electro-hydraulic push rod 23 pushes down the shearing blade 24, which presses down on the transverse wire 20, causing it to press against the upper side of the longitudinal wire 12. At this time, the shearing blade 24 does not contact the shearing support table 25, thus the shearing blade 24 only presses down on the transverse wire 20 and does not cut it. Then, the first transverse electric slider 5 is activated, driving the first electric telescopic push rod 6 and the welding execution component 7 to slide. The output end of the first electric telescopic push rod 6 allows the welding execution component 7 to move up and down. The welding execution component 7 is an existing automatic identification spot welding device, a mature technology, capable of identifying the transverse wire 20 and the longitudinal wire 12 during movement. At the intersection points, spot welding is performed. The specific structure and operating principle of the welding execution component 7 are directly referenced from existing technology and will not be elaborated here. During the process of spot welding and fixing the intersection points of the longitudinal wire 12 and the transverse wire 20 one by one, the second lateral electric slider 27 returns to its initial position and repeats the above operation, so that the clamping block 31 re-clamps the transverse wire 20 close to the through hole 21. After the spot welding is completed, the output end of the second electric hydraulic push rod 23 pushes down the shearing blade 24, so that the transverse wire 20 is pressed off on the shearing support table 25. Then the shearing blade 24 returns to its original position. After that, the drive motor 15 is started, and the drive roller 14 presses the transmission longitudinal wire 12, so that the welded transverse wire 20 moves one set unit and then stops. Then the second lateral electric slider 27 is started.The second lateral electric slider 27 repeats the above sliding motion, arranging the new horizontal wires 20 on the vertical wires 12, after which a new round of spot welding can be performed. It should be noted that all the above processes are integrated and controlled by an integrated PLC control circuit. This technical solution has an integrated control system that can set the parameters of the above device as needed. This technical solution does not rely on manual wire laying; it can automatically lay the next horizontal wire after the spot welding of a single horizontal wire is completed, increasing the efficiency of horizontal wire laying. Compared with manual wire laying, its accuracy and perpendicularity are better, avoiding a decrease in the welding quality of the metal mesh, and avoiding the dangers of manual wire laying, such as inhaling the fumes generated during welding, which can cause health hazards.
