Description

Technical Field

[0001] The present invention relates to the technical field of I-beam production, and specifically to a welding forming device and method for I-beam production. Background Technique

[0002] An I-beam is a long steel bar with an I-shaped cross-section, a common building steel, widely used in industrial factories, large-span frame structures, high-rise buildings, etc., and can be used to construct structural components such as the frames, beams, and columns of buildings, providing strong support for buildings.

[0003] At present, the production processes of I-beams mainly include hot rolling forming and welding forming. Among them, welding forming is a method of cutting steel plates into components with specific shapes and then combining them into an I-shaped cross-section through a welding process. When submerged arc welding is used for welding, during the welding process of thick plates (plate thickness ≥ 12 mm), wide welds, or high-speed welding (speed ≥ 60 cm / min), due to the scattering of the welding flux, the welding flux is unevenly distributed in the weld part, resulting in unqualified appearance quality during welding. Secondly, after welding is completed, due to some welding flux adhering to the welding slag, it causes waste of the welding material. In view of the above problems, the inventor proposes a welding forming device and method for I-beam production to solve the above problems. Summary of the Invention

Then, the unused welding flux is sucked and recycled through the material suction pipe 108. Step 2: Start the first motor 216 to drive the cross bar 213 to rotate forward and backward. Through the rotation of the cross bar 213, the knocking rod 207 swings reciprocally and the second material shoveling frame 217 and the first material shoveling frame 202 move reciprocally, so that the welding slag is separated from the web and the flange. Step 3: Start the slag suction device 305. Through the cooperation between the slag suction device 305 and the slag suction pipe 204, the welding slag is collected, and the broken welding slag is transported inside the screening box 401 and falls on the screening plate 402. Step 4: Start the second motor 409 to drive the mounting rod 407 to rotate. Through the rotation of the mounting rod 407, the screening plate 402 moves reciprocally and the feeding rod 405 rotates, screening the welding slag and the welding flux adhering to the welding slag, and transporting the screened welding flux into the storage box 306.

[0047] Working principle: First, turn on the feeding device 302, the welding device 303, and the material suction device 304 respectively. At this time, the welding flux is transported to the side where the web and the flange are in contact through the feeding pipe 106, and the web and the flange are welded through the welding rod 107. Then, the unused welding flux is sucked and recycled through the material suction pipe 108. Secondly, turn on the first motor 216 to drive the cross bar 213 to rotate forward and backward. The rotation of the cross bar 213 drives the second bevel gear 215 to rotate. The rotation of the second bevel gear 215 drives the first bevel gear 214 to rotate. The rotation of the first bevel gear 214 drives the rotating rod 210 to rotate. The rotation of the rotating rod 210 drives the transmission rod 208 to rotate. The rotation of the transmission rod 208 drives the vertical rod 206 to rotate. The rotation of the vertical rod 206 drives the knocking rod 207 to swing, making the knocking rod 207 contact the end of the transportation device 5 far away from the welding slag, separating the welding slag from the web and flange plate; Moreover, the rotation of the cross bar 213 drives the rotating rod 219 to rotate. The rotation of the rotating rod 219 drives the second cam 220 to rotate. At this time, the cooperation between the second cam 220 and the second spring 221 drives the second slag shoveling frame 217 to reciprocate. At this time, the second slag shoveling frame 217 close to the transportation device 5 knocks the welding slag, making the welding slag loose. And the other second slag shoveling frame 217 shovels the welding slag, separating the welding slag from the web; Then, the rotation of the transmission rod 208 drives the first cam 211 to rotate. At this time, the cooperation between the first cam 211 and the first spring 203 drives the first slag shoveling frame 202 to reciprocate. At this time, the side of the first slag shoveling frame 202 close to the transportation device 5 knocks the welding slag, making the welding slag loose. And the other side of the first slag shoveling frame 202 shovels the welding slag, separating the welding slag from the flange plate. At the same time, the movement of the first slag shoveling frame 202 drives the slag suction pipe 204 to move. The movement of the slag suction pipe 204 drives the slag crushing plate 205 to move. The slag crushing plate 205 crushes the welding slag; Then, turn on the slag suction device 305. The cooperation between the slag suction device 305 and the slag suction pipe 204 collects the welding slag, transporting the crushed welding slag into the screening box 401, and making the welding slag fall on the screening plate 402; Finally, turn on the second motor 409 to drive the mounting rod 407 to rotate. The rotation of the mounting rod 407 drives the third cam 408 to rotate. At this time, the cooperation between the third cam 408 and the third spring 410 drives the connecting frame 403 to reciprocate. The movement of the connecting frame 403 drives the screening plate 402 to move. The movement of the screening plate 402 screens the welding slag and the welding agent adhering to the welding slag. At this time, the screened welding agent falls to the bottom of the screening box 401. At this time, the rotation of the mounting rod 407 drives the feeding rod 405 to rotate, transporting the screened welding agent, and making the welding agent transported into the storage box 306.
