The conveying rollers 11 are horizontally and evenly arranged on the upper end surface of the base 4. The conveying rollers 11 are rotatably connected to the base 4. The rotating motors 12 are fixedly connected to the base 4. The output shafts of the rotating motors 12 are coaxially connected to the conveying rollers 11. The spacing component 13 includes support blocks 131, a number of isolation blocks 132, two driving lead screws 133 and two transverse movement motors 134. The two driving lead screws 133 are horizontally arranged and extend along the length direction of the base 4. The transverse movement motors 134 are fixedly connected to the base 4. The output shafts of the transverse movement motors 134 are coaxially connected to the driving lead screws 133. The two ends of the support block 131 are respectively in threaded cooperation with the two driving lead screws 133. The two sides of the support block 131 are respectively slidably connected to the two sides of the base 4. The isolation blocks 132 are fixedly connected to the lower end surface of the support block 131. The isolation blocks 132 are vertically arranged. The isolation blocks 132 are evenly arranged and there is a gap between the two isolation blocks 132.

[0034] Refer to Figure 1 and Figure 2 , place the flat steel above the conveying rollers 11, start the rotating motor 12, the rotating motor 12 drives the conveying rollers 11 to rotate, and the conveying rollers 11 drive the flat steel to be conveyed. While the flat steel is being conveyed, the isolation blocks 132 space the flat steel. At the same time, the driving lead screws 133 rotate, driving the support block 131 to move transversely, and the support block 131 drives the isolation blocks 132 to move transversely, thus facilitating the maintenance of the distance between the flat steels.

[0035] Refer to Figure 1 and Figure 2 , the feeding mechanism 2 includes a magnet bar 21, a rotating rod 22, a driving motor 23, a conveying component 24, a placing component 25 and a rectifying component 26. There is a support frame 27 above the base 4. The driving motor 23 is fixedly connected to the support frame 27. The output shaft of the driving motor 23 is coaxially connected to the rotating rod 22. The rotating rod 22 is rotatably connected to the support frame 27. The magnet bar 21 is fixedly connected to the outside of the rotating rod 22. The magnet bar 21 is an electromagnet. The rotating rod 22 is horizontally arranged. The length of the rotating rod 22 is equal to the length of the magnet bar 21. The rotating rod 22 is arranged at one end of the support frame 27 close to the welding mechanism 3.

[0036] Refer to Figure 1 and Figure 2 , the conveying component 24 includes two inclined plates 241 and two stoppers 242. The two inclined plates 241 are inclined and arranged on both sides of the support frame 27. The stoppers 242 are arranged at the ends of the inclined plates 241 close to the rotating rod 22. The stoppers 242 are fixedly connected to the inclined plates 241. The stoppers 242 are inclined. The two inclined plates 241 are parallel to each other. There is a gap between the two inclined plates 241.

[0037] Refer to Figure 1 andFigure 2 Several crossbars are placed on the inclined plate 241. The inclined plate 241 tilts, and the crossbars slide along the inclined plate 241 to the stopper 242. The stopper 242 blocks the crossbars, which helps prevent them from sliding. When the crossbars are transported to the stopper 242, the magnet strip 21 is energized, starting the drive motor 23. The output shaft of the drive motor 23 drives the rotating rod 22 to rotate, which in turn drives the magnet strip 21 to rotate. The magnet strip 21 attracts the crossbars at the stopper 242, and the crossbars rotate with the magnet strip 21, thereby facilitating the transport of the crossbars.

[0038] Reference Figure 1 and Figure 3 The correction assembly 26 includes a resistance block 261, a lifting rod 262, two turntables 263, a limit block 264 and a transmission member. The two turntables 263 are rotatably connected to the two sides of the support frame 27, and the lifting rod 262 is rotatably connected to the eccentricity of the two turntables 263. The end of the lifting rod 262 away from the turntable 263 is rotatably connected to the upper end of the resistance block 261. The limit block 264 is provided with a slide groove. The resistance block 261 is slidably connected to the slide groove of the limit block 264. The turntable 263 rotates, and the resistance The block 261 slides in the sliding groove of the limit block 264, the interference block 261 is located directly above the rotating rod 22, and a pressing groove for inserting the cross bar is provided below the interference block 261. The transmission parts include a driving gear 265, a driving chain 266 and a driven gear 267. The rotating rod 22 passes through one end of the supporting frame 27 and is coaxially connected to the driving gear 265. The driven gear 267 is coaxially connected to one of the turntables 263. The driving chain 266 is respectively engaged with the driving gear 265 and the driven gear 267.

[0039] Reference Figure 1 and Figure 3 When the rotating rod 22 transports the crossbar, it drives the driving gear 265 to rotate, the driving gear 265 drives the driving chain 266 to rotate, the driving chain 266 drives the driven gear 267 to rotate, and the driven gear 267 drives the turntable 263 to rotate. When the magnet bar 21 rotates, the lifting rod 262 descends, and the lifting rod 262 cooperates with the limit block 264, causing the interference block 261 to move downward along the direction of the limit block 264 slide. When the magnet bar 21 rotates to the top, the interference block 261 interferes with the crossbar, straightening the crossbar, thereby facilitating the transportation of qualified crossbars. When welding the crossbars, this helps reduce the risk of bent crossbars being welded to flat steel, thereby improving product qualification rates and reducing the waste of raw materials. While transporting the crossbars, the crossbars are straightened, which helps reduce the processing process and thus helps improve processing efficiency.

[0040] Reference Figure 1 and Figure 3, the placing component 25 includes two supporting plates 251, two lifting cylinders 252, two conveying rods 253, two transverse moving cylinders 254, a fixing block 255 and a driving oil cylinder 256. The supporting plates 251 are located on both sides of the base 4. The supporting plates 251 are horizontally arranged. The two lifting cylinders 252 are fixedly connected to both sides of the base 4. The lifting cylinders 252 are vertically arranged. The two supporting plates 251 are respectively fixedly connected to the piston rods of the two lifting cylinders 252. A first groove for placing the cross bar is formed above the supporting plate 251. The conveying rod 253 is located below the rotating rod 22. The conveying rod 253 is horizontally arranged. A second groove for placing the cross bar is formed on the upper end surface of the conveying rod 253. The cylinder body of the transverse moving cylinder 254 is fixedly connected to the supporting frame 27. The transverse moving cylinder 254 is horizontally arranged. The piston rod of the transverse moving cylinder 254 is fixedly connected to the conveying rod 253. A bracket 257 is fixedly connected to the upper end of the base 4. The driving oil cylinder 256 is fixedly connected to the upper end of the bracket 257. The driving oil cylinder 256 is vertically arranged. The piston rod of the driving oil cylinder 256 is fixedly connected to the fixing block 255. A slot for inserting the cross bar is formed on the lower end surface of the fixing block 255.

[0041] Referring to Figure 1 and Figure 3 , when the magnet bar 21 rotates to the directly below, the magnet bar 21 is powered off, and the cross bar falls into the second groove of the conveying rod 253. The transverse moving cylinder 254 is started. The piston rod of the transverse moving cylinder 254 extends, driving the conveying rod 253 to move horizontally between the two supporting plates 251. The lifting cylinder 252 is started. The piston rod of the lifting cylinder 252 extends, driving the supporting plate 251 to rise, so that the cross bar abuts against the first groove of the supporting plate 251. The piston rod of the transverse moving cylinder 254 contracts, driving the conveying rod 253 to reset. The piston rod of the lifting cylinder 252 contracts, driving the supporting plate 25 to descend. The supporting plate 251 places the cross bar above the flat steel. Then the driving oil cylinder 256 is started. The piston rod of the driving oil cylinder 256 extends, driving the fixing block 255 to descend, so that the cross bar is inserted into the slot of the fixing block 255, and the cross bar is laid flat above the flat steel. At the same time, it is beneficial to reduce the phenomenon of the cross bar sliding, and then it is convenient to weld the cross bar to the flat steel.

[0042] Referring to Figure 1 and Figure 3 , the welding mechanism 3 includes a plurality of welding torches (not shown in the figure) for welding the cross bar to the flat steel and a blower 31. The welding torches are arranged in the fixing block 255. The welding torches face the slot. The blower 31 is arranged on the upper end surface of the base 4. The blower 31 is arranged on the side of the fixing block 255 away from the conveying rod 253. The blower 31 is horizontally arranged below the conveying roller 11.

[0043] After the fixed block 255 fixes the cross bar, start the welding torch. The welding torch welds the cross bar onto the flat steel. After the cross bar is welded, the conveying roller 11 conveys the flat steel. Start the blower 31. The blower 31 cools the cross bar, which is convenient for accelerating the cooling of the cross bar and is also beneficial to reducing the subsequent cooling treatment operation of the steel grating, thereby improving the processing efficiency.

[0044] The implementation principle of a steel grating welding and processing device according to an embodiment of the present application is as follows: When the cross bar needs to be welded onto the flat steel, place the flat steel above the conveying roller 11. Start the rotating motor 12. The rotating motor 12 drives the conveying roller 11 to rotate. The conveying roller 11 drives the flat steel to be conveyed. While the flat steel is being conveyed, the isolation block 132 spaces the flat steel. At the same time, drive the lead screw 133 to rotate, drive the support block 131 to move horizontally, and the support block 131 drives the isolation block 132 to move horizontally to maintain the distance between the flat steels.

[0045] Place several cross bars on the inclined plate 241. The inclined plate 241 is inclined, and the cross bars slide along the inclined plate 241 to the stop block 242. The stop block 242 blocks the cross bars. When the cross bars are conveyed to the stop block 242, the magnet bar 21 is energized. Start the drive motor 23. The output shaft of the drive motor 23 drives the rotating rod 22 to rotate. The rotating rod 22 drives the magnet bar 21 to rotate. The magnet bar 21 adsorbs the cross bars at the stop block 242, and the cross bars rotate with the magnet bar 21.

[0046] When the rotating rod 22 conveys the cross bars, it drives the driving gear 265 to rotate. The driving gear 265 drives the driving chain 266 to rotate. The driving chain 266 drives the driven gear 267 to rotate. The driven gear 267 drives the turntable 263 to rotate. When the magnet bar 21 rotates, the lifting rod 262 descends. The lifting rod 262 cooperates with the limit block 264 to make the abutting block 261 move downward along the chute direction of the limit block 264. When the magnet bar 21 rotates to directly above, the abutting block 261 abuts against the cross bar and straightens the cross bar.

[0047] When the magnet bar 21 rotates to directly below, the magnet bar 21 is de-energized, and the cross bars fall into the second groove of the conveying rod 253. Start the transverse moving cylinder 254. The piston rod of the transverse moving cylinder 254 extends, driving the conveying rod 253 to move horizontally between the two supporting plates 251. Start the lifting cylinder 252. The piston rod of the lifting cylinder 252 extends, driving the supporting plate 251 to rise, so that the cross bars abut against the first groove of the supporting plate 251. The piston rod of the transverse moving cylinder 254 contracts, driving the conveying rod 253 to reset. The piston rod of the lifting cylinder 252 contracts, driving the supporting plate 251 to descend. The supporting plate 251 places the cross bars above the flat steel. Then start the driving oil cylinder 256. The piston rod of the driving oil cylinder 256 extends, driving the fixed block 255 to descend, so that the cross bars are inserted into the slots of the fixed block 255, and the cross bars are laid flat above the flat steel.

[0048] After the fixing block 255 fixes the cross bar, start the welding torch. The welding torch welds the cross bar onto the flat steel. After the cross bar is welded, the conveying roller 11 conveys the flat steel, and start the blower 31. The blower 31 cools the cross bar.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
