Description

Technical Field

[0001] This invention relates to the technical field of steel plate welding and processing, and in particular to a high-precision and environmentally friendly steel plate welding machine. Background Technology

[0002] With the continuous development of the modern economy, steel plates are one of the most commonly used materials in infrastructure construction, building construction, and bridge construction. Due to their high hardness and corrosion resistance, they are widely used in many fields. When using steel plates, they need to be welded according to actual needs.

[0003] When welding two steel plates, their edges are joined together, and the joint is welded using a welding torch. This welding process generates a large amount of fumes, which can negatively impact the production workshop environment and pose health risks to workers. Summary of the Invention

[0004] In order to reduce the amount of welding fumes emitted into the outside air during the steel plate welding process, this application provides a high-precision environmentally friendly steel plate welding machine.

[0005] This application provides a high-precision, environmentally friendly steel plate welding machine, including a frame, a support platform on the frame, support spikes for placing steel plates on the support platform, a gantry frame on the support platform, a drive assembly and a welding torch on the gantry frame, the drive assembly for driving the welding torch to move, and a dust removal assembly above the support platform, the dust removal assembly including a suction hood connected to the nozzle of the welding torch, the suction hood being connected to an external dust collector.

[0006] By adopting the above technical solution, when welding steel plates, the steel plates are placed above the support platform and supported by support spikes. Two steel plates are spliced ​​together and welded using a welding torch. Driven by the drive assembly, the welding torch moves along the length of the weld seam at the splice of the two steel plates to weld them together. An external dust collector acts on the suction hood to extract the fumes generated during the welding process, reducing the possibility of welding fumes being directly emitted into the outside air and causing environmental pollution, while also reducing the harm to the health of production personnel.

[0007] Optionally, the suction cover surrounds the nozzle of the welding gun, and the suction cover is detachably threaded to the nozzle of the welding gun.

[0008] By adopting the above technical solution, the suction hood surrounds the nozzle of the welding gun, which can more fully extract the welding fumes and further improve the extraction effect of welding fumes. At the same time, the suction hood and the nozzle of the welding gun are detachably connected, which facilitates the regular replacement of the suction hood.

[0009] Optionally, a clamping assembly is provided above the support platform. The clamping assembly includes a clamping wheel, which is linked to the welding gun. The clamping wheel is located near the weld and abuts against the surface of the steel plate.

[0010] By adopting the above technical solution, when the welding torch welds the steel plates, the weld seam of the two steel plates will deform due to the heat generated during the welding process. By using the clamping roller to clamp the steel plates, the steel plates are kept in a horizontal state during the welding process, reducing the possibility of deformation of the steel plates during the welding process. The two steel plates are always in a horizontal state, which can improve the welding accuracy of the steel plates and make the welding effect of the steel plates better.

[0011] Optionally, the positioning wheel includes several clamping rings, which are coaxially spaced in the horizontal direction. The clamping rings are hollow inside. Several suction ports are evenly opened on the side wall of the clamping rings near the welding gun. A main support tube is coaxially arranged on the clamping rings. The main support tube is rotatably arranged above the support platform. The clamping rings and the main support tube are interconnected. The main support tube is connected to an external dust collector.

[0012] By adopting the above technical solution, each clamping ring is provided with a suction port, which can increase the amount of welding fumes generated during the welding process of steel plates per unit time and reduce the possibility of welding fumes directly diffusing into the outside air. The clamping ring not only clamps the steel plate and prevents the steel plate from deforming, but also plays the role of suctioning welding fumes.

[0013] Optionally, a plurality of auxiliary support tubes are provided between the clamping ring and the main support tube. The plurality of auxiliary support tubes are evenly arranged along the circumference of the main support tube. One end of the auxiliary support tube is connected to the clamping ring, and the other end of the auxiliary support tube is connected to the main support tube.

[0014] By adopting the above technical solution, the auxiliary support pipe provides support between the clamping ring and the main support pipe, ensuring that the clamping ring and the main support pipe are coaxially set, thus guaranteeing the clamping ring's tightness against the steel plate. At the same time, welding fumes flow from the suction port of the clamping ring through the auxiliary support pipe into the main support pipe, and are finally extracted from the main support pipe by an external dust collector.

[0015] Optionally, a plurality of reinforcing tubes are provided between adjacent abutment rings, and the plurality of reinforcing tubes are evenly arranged along the circumferential direction of the abutment rings, with both ends of the reinforcing tubes connected to the corresponding abutment rings.

[0016] By adopting the above technical solution, the setting of the reinforcing tube makes the connection between adjacent clamping rings more stable, thereby improving the overall strength of the clamping wheel and enabling the clamping wheel to always maintain stable clamping with the steel plate.

[0017] Optionally, the clamping components are provided in two sets, with each set corresponding to one side of the welding torch, and the two sets of clamping components are symmetrically arranged about the center line of the support platform in the length direction.

[0018] By adopting the above technical solution, the two sets of clamping components correspond one-to-one with the two steel plates being welded. Each set of clamping components can clamp the corresponding steel plate, which can further reduce the possibility of deformation of the steel plate during the welding process and further improve the welding quality of the steel plate. At the same time, the two clamping wheels can simultaneously suck up the welding fumes generated during the welding process, further reducing the possibility of welding fumes spreading into the external environment.

[0019] Optionally, the drive assembly includes a lead screw rotatably connected to the gantry frame, a lead screw nut rotatably connected to the lead screw, a welding torch connected to the lead screw nut via a first adapter plate, a guide rail fixedly connected to the gantry frame, a slider fixedly connected to the first adapter plate, the slider being slidably connected to the guide rail, and the main support tube connected to the first adapter plate via a second adapter plate, the main support tube being rotatably connected to the second adapter plate.

[0020] By adopting the above technical solution, the lead screw rotates, providing driving force for the sliding of the lead nut along the length of the lead screw. The first adapter plate is fixedly connected to the lead nut and slides along the length of the lead screw under the guidance and limiting action of the guide rail and the slider. This realizes the sliding of the first adapter plate along the length of the lead screw, allowing the clamping wheel to move synchronously with the welding torch during the welding process. During the welding process of the welding torch on the entire weld seam, the clamping wheel can always be at the current welding position of the steel plate, reducing the possibility of deformation of the steel plate. At the same time, the fumes generated during the welding of the steel plate are promptly extracted and removed, further improving the dust removal effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When welding steel plates, the steel plates are placed on a support platform and supported by support spikes. Two steel plates are spliced ​​together and welded using a welding torch. Driven by the drive assembly, the welding torch moves along the length of the weld seam at the splice of the two steel plates to weld them. An external dust collector acts on the suction hood to extract the fumes generated during the welding process, reducing the possibility of welding fumes being directly emitted into the outside air and causing environmental pollution, while also reducing the harm to the health of production personnel.

[0023] 2. When welding steel plates with a welding torch, the weld seam between the two steel plates will deform due to the heat generated during the welding process. By using a clamping roller to clamp the steel plates, the steel plates are kept horizontal during the welding process, reducing the possibility of deformation. Keeping the two steel plates horizontal can improve the welding accuracy and make the welding effect of the steel plates better.

[0024] 3. Each clamping ring is equipped with a suction port, which can increase the amount of welding fumes extracted per unit time during the welding process of steel plates, and reduce the possibility of welding fumes directly diffusing into the outside air. The clamping rings not only clamp the steel plates to prevent deformation, but also extract welding fumes. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a high-precision, environmentally friendly steel plate welding machine.

[0032] Reference Figure 1A high-precision, environmentally friendly steel plate welding machine includes a frame 1. A horizontally arranged support platform 2 is fixedly connected to the frame 1. Several support spikes 3 for placing steel plates are evenly arranged on the support platform 2. The support spikes 3 are vertically arranged and fixedly connected to the support platform 2. The spikes of the support spikes 3 abut against the steel plates. A portal frame 4 is fixedly connected to the support platform 2. The length direction of the portal frame 4 is consistent with the width direction of the support platform 2. A welding torch 5 and a drive assembly 6 are fixedly connected to the portal frame 4. The drive assembly 6 drives the welding torch 5 to slide along the length direction of the portal frame 4. A dust removal assembly 10 is provided on the welding torch 5. A clamping assembly 11 is provided on both sides of the welding torch 5. The clamping assembly 11 abuts against the surface of the steel plate. The two sets of clamping assemblies 11 are symmetrically arranged along the center line of the length direction of the support platform 2.

[0033] Reference Figure 1 When welding steel plates, two steel plates are placed simultaneously on the support platform 2, supported by the support spikes 3, and the two steel plates are joined together. The drive assembly 6 provides driving force for the movement of the welding torch 5, causing the welding torch 5 to move along the joint where the two steel plates are joined together to complete the welding of the steel plates. During the welding process, the dust extraction assembly 10 extracts the welding fumes generated during the welding process, reducing the possibility of the welding fumes directly diffusing into the outside air, improving the environment in the production workshop, and reducing the possibility of harm to the health of production personnel. During the welding process, the clamping assembly 11 always keeps in close contact with the steel plate, reducing the possibility of the steel plate deforming due to heat during the welding process and improving the welding accuracy of the steel plate.

[0034] Reference Figure 1 and Figure 2 The drive assembly 6 includes a lead screw 61, the length direction of which is consistent with the length direction of the gantry frame 4. The lead screw 61 is horizontally set and rotatably connected to the gantry frame 4. A motor 62 is fixedly connected to the gantry frame 4. The output shaft of the motor 62 is coaxially fixedly connected to one end of the lead screw 61. A nut 63 is threadedly connected to the lead screw 61. The welding torch 5 is connected to the nut 63 through a first adapter plate 7. The first adapter plate 7 is horizontally set and fixedly connected to the nut 63. The welding torch 5 is fixedly connected to the first adapter plate 7. The nozzle of the welding torch 5 is set downward. The drive assembly 6 also includes two guide rails 64 fixedly connected to the gantry frame 4. The guide rails 64 are parallel to the lead screw 61. The lead screw 61 is located between the two guide rails 64. A slider 65 is fixedly connected to the first adapter plate 7 at the position corresponding to the guide rails 64. The slider 65 is slidably connected to the guide rails 64.

[0035] Reference Figure 1 and Figure 2The dust removal assembly 10 includes a suction shroud 101 coaxially connected to the nozzle of the welding torch 5. The suction shroud 101 is threadedly connected to the nozzle of the welding torch 5 and surrounds the nozzle of the welding torch 5. A first suction pipe 102 is connected to the suction shroud 101 and is connected to an external dust collector (not shown).

[0036] Reference Figure 1 and Figure 2 When the motor 62 starts, it drives the lead screw 61 to rotate. Under the guidance and limiting action of the guide rail 64 and the slider 65, the first adapter plate 7 slides along the length direction of the lead screw 61 to realize the welding of the two steel plates. During the welding process of the welding gun 5 on the steel plates, the dust collector creates a negative pressure in the suction hood 101 to draw out the welding fumes and reduce the amount of welding fumes emitted into the atmosphere.

[0037] Reference Figure 3 The clamping assembly 11 includes a clamping wheel 111, which includes several coaxially arranged clamping rings 1111. The outer ring wall of the clamping rings 1111 abuts against the surface of the steel plate.

[0038] Reference Figure 3 By abutting the steel plate surface with the clamping wheel 111, the possibility of deformation during steel plate welding is reduced. The two steel plates are in a horizontal state, which can improve the welding accuracy of the steel plates and make the welding effect of the steel plates better.

[0039] Reference Figure 3 The central axis of the clamping ring 1111 is horizontally set, and several clamping rings 1111 are spaced apart along the length of the support platform 2. The interior of the clamping ring 1111 is hollow, and several suction ports 11111 are evenly opened on the side wall of the clamping ring 1111 near the welding torch 5. The clamping assembly 11 also includes a horizontally set main support tube 1112. The main support tube 1112 is coaxially set with the clamping ring 1111 and is connected to it. The main support tube 1112 is a rigid tube, and the end of the main support tube 1112 near the welding torch 5 is closed. Two second adapter plates 8 are fixedly connected to the adapter plate 7 at intervals. The second adapter plates 8 are perpendicular to the first adapter plate 7. The main support pipe 1112 is rotatably connected to the second adapter plates 8. The other end of the main support pipe 1112 is provided with a second suction pipe 13. The second suction pipe 13 is connected to an external dust collector. The second suction pipe 13 is connected to the second suction pipe 13 through an adapter pipe 12. A third adapter plate 9 is fixedly connected to the second adapter plate 8. The adapter pipe 12 is fixedly connected to the third adapter plate 9 and rotatably connected to the main support pipe 1112.

[0040] Reference Figure 3Under the action of the external dust collector, the welding fumes are drawn into the clamping ring 1111 through the suction port 11111, flow through the main support pipe 1112, and finally discharged from the second suction pipe 13. The clamping ring 1111 not only clamps the steel plate to prevent deformation, but also has the effect of suctioning the welding fumes, further reducing the amount of welding fumes directly emitted into the outside air.

[0041] Reference Figure 3 A plurality of auxiliary support pipes 1113 are provided between the clamping ring 1111 and the main support pipe 1112. The plurality of auxiliary support pipes 1113 are evenly arranged along the circumference of the main support pipe 1112. One end of the auxiliary support pipe 1113 is connected to the main support pipe 1112, and the other end of the auxiliary support pipe 1113 is connected to the clamping ring 1111. A plurality of reinforcing pipes 1114 are provided between adjacent clamping rings 1111. The plurality of reinforcing pipes 1114 are evenly arranged along the circumference of the clamping ring 1111. The reinforcing pipes 1114 are horizontally arranged. One end of the reinforcing pipe 1114 is connected to one of the clamping rings 1111, and the other end of the reinforcing pipe 1114 is connected to another clamping ring 1111.

[0042] Reference Figure 3 The auxiliary support pipe 1113 provides support between the clamping ring 1111 and the main support pipe 1112, ensuring that the clamping ring 1111 and the main support pipe 1112 are coaxially aligned, thus guaranteeing the clamping ring 1111's tightness against the steel plate. At the same time, the reinforcing pipe 1114 makes the connection between adjacent clamping rings 1111 more stable, thereby improving the overall strength of the clamping wheel 111 and ensuring that the clamping wheel 111 can always maintain a stable tightness against the steel plate.

[0043] The implementation principle of this application embodiment is as follows: Production personnel first place two steel plates on the support spike 3, causing the clamping wheel 111 to contact the surface of the steel plates, and then join the edges of the two steel plates together. Simultaneously, the motor 62 and welding torch 5 are started. The motor 62 drives the lead screw 61 to rotate, causing the welding torch 5 to move. During the movement of the welding torch 5, welding is performed at the joint of the two steel plates. During the welding process, an external dust collector is started to extract the welding fumes. The welding fumes are extracted from the first suction pipe 102 through the suction hood 101; the welding fumes pass through the suction port 11111 on the clamping ring 1111, through the reinforcing pipe 1114 and the auxiliary support pipe 1113, and are extracted from the second suction pipe 13 through the main support pipe 1112.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
