Description

Technical Field

[0001] This invention relates to the field of aluminum formwork welding technology, and in particular to a precision welding device for aluminum formwork ribs. Background Technology

[0002] Aluminum formwork (aluminum alloy building formwork) is widely used in construction as a green technology product due to its advantages such as "low weight, quick demolding, and reusability," and is a core component in the industrialization and standardization of construction. During the preparation of aluminum formwork, a varying number of reinforcing bars are welded to the base plate according to its dimensions.

[0003] Large factories typically employ automated robotic welding processes. However, the actual temperature of the "liquid metal zone" formed by the melting of the base material after the electric arc acts on the workpiece is usually slightly higher than the melting point of the base material (for example, when welding aluminum formwork, the temperature of the molten pool is about 700℃-900℃, only tens to two hundred degrees Celsius higher than the melting point of aluminum). Therefore, arc welding is usually performed by spot welding, fixing the ribs and aluminum formwork only through a few connection points. During repeated disassembly and assembly and load-bearing in construction, the stress concentration at the connection points can easily lead to desoldering and cracking, directly affecting the reuse life of the aluminum formwork.

[0004] Therefore, this application provides a precision welding device for aluminum formwork ribs to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a precise welding device for aluminum formwork ribs to solve the problem that the existing welded ribs and aluminum formwork are fixed to the ribs and aluminum formwork only through a few connection points. When the ribs and aluminum formwork are repeatedly disassembled and assembled and subjected to loads during construction, the stress concentration at the connection points can easily cause the welds to break off and crack, which directly affects the reuse life of the aluminum formwork.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A precision welding device for aluminum formwork ribs includes a workbench with crossbeams fixedly installed on both sides of its top; a welding structure comprising a trapezoidal shell, a wire feeding assembly, and a cooling assembly; the wire feeding assembly includes a housing, with a motor fixedly installed on the side wall near a connecting block; a drive gear is provided inside the housing, and the motor output is rotatably connected to the drive gear; the drive gear meshes with transmission gears, and two sets of transmission gears are provided, symmetrically arranged about a line parallel to the center of the housing; the side walls of the transmission gears are fixed. A clamping disc is installed, with a clamping groove on one side wall of the clamping disc. A support bar is fixedly installed at the center of the interior of the housing. An auxiliary tube is fixedly installed on the inner side of the support bar. An auxiliary tube is inserted into the top of the housing and an auxiliary tube is inserted into the bottom of the housing. A screw is rotatably connected to the end of the housing away from the drive gear. A support seat is threadedly connected to the end of the screw near the drive gear. A clamping disc is rotatably connected to the upper and lower ends of the support seat. A clamping groove is opened on the side wall of the clamping disc. A limit block is fixedly installed at the end of the support seat away from the screw.

[0008] Optionally, the cooling component includes a heat sink, with connectors fixedly inserted on both sides of the heat sink. Each connector is fixedly connected to a C-shaped block. A water tank is formed inside the C-shaped block. A water outlet pipe is provided on the top of one side of the C-shaped block near the trapezoidal shell. The water outlet pipe is fixedly inserted into the water tank. A water inlet pipe is provided on the side of the water outlet pipe away from the trapezoidal shell. The water inlet pipe is fixedly inserted into the water tank. The outer wall of the auxiliary pipe is provided with a spiral tube. Both ends of the spiral tube are respectively connected to the top of the two C-shaped blocks. A sleeve is provided on the outer wall of the spiral tube. The top of the sleeve is fixedly connected to the bottom of the outer shell.

[0009] Optionally, a connecting block is fixedly installed on the outer wall of the end of the trapezoidal shell, a flange is fixedly connected to the end of the connecting block, and the top of the trapezoidal shell away from the connecting block is inserted and fixed to the outer shell.

[0010] Optionally, a laser module is inserted and fixed to the top of the trapezoidal shell near the connecting block, and an air inlet pipe is inserted and fixed to the output end of the laser module.

[0011] Optionally, a support block is fixedly installed at the center of the crossbeam, and a support groove is formed at the center of the support block.

[0012] Optionally, the support groove is slidably connected to the heat sink, and a rotating rod is fixedly installed on the inner side of the crossbeam. Multiple sets of rotating rods are provided, and the multiple sets of rotating rods are symmetrically arranged with respect to the center position of the crossbeam.

[0013] Optionally, the outer wall of the rotating rod is rotatably connected to a roller, and multiple sets of rollers are provided, with the multiple sets of rollers symmetrically arranged around the center position of the rotating rod.

[0014] Optionally, an auxiliary plate is fixedly installed at the center of the top of the crossbeam, and an aluminum template is provided on the top of the roller, with the bottom of the aluminum template in contact with the surface of the roller.

[0015] Optionally, a rib is provided at the center of the top of the aluminum template, and the bottom of the rib is in contact with the top surface of the aluminum template.

[0016] Optionally, support columns are fixedly installed around the bottom of the workbench.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, continuous wire welding is achieved through the coordinated operation of the wire feeding assembly and the laser module. The motor-driven gear transmission structure drives the clamping disc to stably feed the wire, and the laser module precisely melts the welding wire, forming a continuous and uniform weld (rather than discrete weld points). This welding method increases the connection area between the ribs and the aluminum formwork by more than 80%, significantly enhancing the connection strength. Even if the aluminum formwork bears construction loads for a long time and undergoes multiple disassembly and reassembly, it can avoid structural failure caused by "few connection points," meeting the core requirements of industrialized construction for aluminum formwork of "high strength and high reusability," and indirectly reducing the cost of formwork procurement and replacement for projects.

[0019] The built-in copper plates in the heat sink quickly absorb residual welding heat from the bottom of the aluminum template, preventing local temperatures from exceeding the aluminum's tolerance threshold. This prevents the aluminum template from burning through or warping, ensuring dimensional accuracy and allowing for direct use without subsequent repairs. The absorbed residual heat is transferred to the welding wire in auxiliary pipe three via a water circulation system, preheating the wire. This shortens the time for the laser module to melt the welding wire, improving welding efficiency and avoiding the energy waste of "extra heating of the welding wire."

[0020] By rotating the screw, the support base can be moved, changing the distance between clamping plate one and clamping plate two, which can accommodate welding wires of different diameters. The welding requirements of different aluminum templates and ribs can be met without changing the wire feeding mechanism, reducing the investment in purchasing special equipment for templates of different specifications and lowering the overall equipment cost.

[0038] like Figures 1 to 8As shown, an embodiment of the present invention provides a precision welding device for aluminum template ribs 117, including a workbench 100, with crossbeams 110 fixedly installed on both sides of the top of the workbench 100; a welding structure 200, which includes a trapezoidal shell 210, a wire feeding assembly 230, and a cooling assembly 250; the wire feeding assembly 230 includes a housing 231, with a motor 232 fixedly installed on the side wall of the housing 231 near the connecting block 211, and a drive gear 233 provided inside the housing 231. The output end of the motor 232 is rotatably connected to the drive gear 233, and the drive gear 233 meshes with a transmission gear 234. There are two sets of transmission gears 234, which are symmetrically arranged about a line parallel to the center of the housing 231. The side wall of the transmission gear 234 is fixedly installed with... The housing 231 is equipped with a clamping disc 235, the side wall of which has a clamping groove 236. A support strip 237 is fixedly installed at the center of the interior of the housing 231, and an auxiliary tube 238 is fixedly installed inside the support strip 237. An auxiliary tube 239 is inserted into the top of the housing 231, and an auxiliary tube 240 is inserted into the bottom of the housing 231. A screw 241 is rotatably connected to the end of the housing 231 away from the drive gear 233. A support base 242 is threadedly connected to the end of the screw 241 near the drive gear 233. A clamping disc 243 is rotatably connected to both ends of the support base 242, the side wall of which has a clamping groove 244. A limit block 245 is fixedly installed at the end of the support base 242 away from the screw 241. The cooling component 250 includes a heat sink 2. 51. Connectors 252 are fixedly inserted on both sides of the heat sink 251. C-shaped blocks 253 are fixedly connected to the connectors 252. A water tank 254 is opened inside the C-shaped block 253. A water outlet pipe 256 is located on the top of one side of the C-shaped block 253 near the trapezoidal shell 210. The water outlet pipe 256 is fixedly inserted into the water tank 254. A water inlet pipe 255 is located on the side of the water outlet pipe 256 away from the trapezoidal shell 210. The water inlet pipe 255 is fixedly inserted into the water tank 254. A spiral tube 257 is provided on the outer wall of the auxiliary tube 240. Both ends of the spiral tube 257 are connected to the tops of the C-shaped blocks 253 on both sides. A sleeve 258 is provided on the outer wall of the spiral tube 257. The top of the sleeve 258 is fixedly connected to the bottom of the outer shell 231. A connecting block 211 is fixedly installed on the outer wall of the end of the trapezoidal shell 210. A flange 212 is fixedly connected to the end of the trapezoidal shell 210. The top of the trapezoidal shell 210, away from the connecting block 211, is inserted and fixed to the outer shell 231. A laser module 220 is inserted and fixed to the top of the trapezoidal shell 210, near the connecting block 211. An air inlet pipe 221 is inserted and fixed to the output end of the laser module 220. The motor 232 drives the drive gear 233 to rotate counterclockwise, thereby causing the two sets of meshing transmission gears 234 to rotate clockwise. The welding wire is located between the first clamping groove 236 and the second clamping groove 244. The rotation of the transmission gear 234 causes the first clamping disk 235 to rotate, thereby conveying the welding wire downward through friction. The first auxiliary pipe 238, the second auxiliary pipe 239, and the third auxiliary pipe 240 can keep the welding wire in a vertical state. A welding wire spool is connected to the outside of the second auxiliary pipe 239.Support bar 237 is used to support and fix auxiliary tube 1 238, and at the same time limits the limiting block 245, thereby determining the minimum distance between clamping groove 1 236 and clamping groove 244 to facilitate clamping the welding wire. When welding ribs 117 to aluminum templates 116 of different thicknesses, welding wires of different sizes are required. By rotating screw 241, the support base 242 drives clamping disc 243 to move left and right, thereby adjusting the distance between clamping groove 1 236 and clamping groove 244 to accommodate welding wires of different sizes. The heat sink 251 has copper sheets inside, which absorb heat to the water inside the heat sink 251, and then flow through the water tank 254 in C-shaped block 253 to the winding tube 257, so that while cooling and absorbing heat at the bottom of aluminum template 116, the welding wire in auxiliary tube 3 240 can be cooled. Preheating effectively utilizes heat. The inlet pipe 255 is connected to a water source, and the outlet pipe 256 is connected to a collection device for easy reuse. Water from the inlet pipe 255 flows from the water tank 254 into the heat sink 251, then into the winding pipe 257, and finally out through the outlet pipe 256. Waterproof gaskets are fixed at the joints 252, water tank 254, and winding pipe 257 to prevent water leakage. A robotic arm is connected to the flange 212, allowing the structure to move left and right, thus ensuring the weld between the aluminum template 116 and the reinforcing rib 117 is straight. Simultaneously, the trapezoidal shell 210 can move the C-shaped block 253 and the heat sink 251, enabling the heat sink 251 to continuously absorb heat from the bottom of the aluminum template 116. An air inlet pipe 221 is connected to a gas cylinder, which can spray protective gas to protect the beam and the molten pool.

[0039] like Figures 1 to 2 As shown, a support block 111 is fixedly installed at the center of the crossbeam 110. A support groove 112 is formed at the center of the support block 111, and the support groove 112 is slidably connected to the heat sink 251. A rotating rod 113 is fixedly installed on the inner side of the crossbeam 110. Multiple sets of rotating rods 113 are symmetrically arranged around the center of the crossbeam 110. Rollers 114 are rotatably connected to the outer wall of the rotating rods 113. Multiple sets of rollers 114 are symmetrically arranged around the center of the rotating rods 113. An auxiliary plate 115 is fixedly installed at the center of the top of the crossbeam 110. An aluminum mold is provided on the top of the rollers 114. The aluminum template 116 has its bottom in contact with the surface of the roller 114. A rib 117 is provided at the center of the top of the aluminum template 116, and the bottom of the rib 117 is in contact with the top surface of the aluminum template 116. Support columns 120 are fixedly installed around the bottom of the workbench 100. The support block 111 is used to support the heat dissipation block 251 and the C-shaped block 253. The heat dissipation block 251 and the C-shaped block 253 can move left and right in the support groove 112. The roller 114 makes it easier and less strenuous for the operator to move the aluminum template 116. The auxiliary plate 115 is used to help position the welding rib 117 of the aluminum template 116.

[0040] The working principle of the technical solution provided by this invention is as follows:

[0041] The reinforcing rib 117 is placed on the aluminum template 116, and then the aluminum template 116 is pushed forward so that the reinforcing rib 117 is aligned with the auxiliary plate 115. Then the welding structure 200 is started, and the motor 232 works to drive the drive gear 233 to drive the transmission gear 234 and the clamping plate 235 to rotate. Then the welding wire is moved downward by friction. At the same time, the laser module 220 works, and the beam melts the welding wire. Meanwhile, the shielding gas in the air inlet pipe 221 protects the beam and the molten pool. Then the copper sheet in the cooling component 250 cools the bottom of the aluminum template 116. The process involves absorbing heat and cooling the material, then transferring the heat to the welding wire in the auxiliary tube 240 via water to preheat the wire. The robotic arm then moves the trapezoidal shell 210, causing the laser module 220, wire feeding assembly 230, and cooling assembly 250 to move along with it, continuously welding the rib 117 and aluminum template 116. This ensures a better connection between the rib 117 and aluminum template 116, preventing the rib 117 and aluminum template 116 from easily detaching due to the limited number of connection points when spot-welded.

To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
