The pressing lifting power mechanism is mounted on the pressing frame, and the output end of the pressing lifting power mechanism drives and connects to the pressing lifting seat.

[0009] A further improvement to the above scheme is that the welded pipe device includes a welded pipe frame, a welded pipe slide connected to the welded pipe frame in a left-right direction, a welded pipe sliding power mechanism for driving the welded pipe slide to slide, and a welded pipe robot set on the welded pipe slide. The welded pipe sliding power mechanism is set on the welded pipe frame, and the output end of the welded pipe sliding power mechanism drives and connects to the welded pipe slide.

[0020] The present invention will be further described below with reference to the accompanying drawings, such as... Figures 2-3As shown, this utility model includes an inclined loading platform 1, an inclined unloading platform 2, a pipe-stopping device 3, a pipe-rotating device 4 disposed between the inclined loading platform 1 and the inclined unloading platform 2, a pipe-pressing device 5 disposed above the pipe-rotating device 4, and a pipe-welding device 6 disposed above the pipe-rotating device 4. The top of the inclined loading platform 1 is an inclined surface structure with the height gradually decreasing from the end away from the pipe-rotating device 4 to the end closer to the pipe-rotating device 4. The top of the inclined unloading platform 2 is also an inclined surface structure with the height gradually decreasing from the end closer to the pipe-rotating device 4 to the end away from the pipe-rotating device 4. The pipe-stopping device 3 is used for alignment. The stainless steel tube 10, with its stainless steel cover 11 mounted on the inclined loading platform 1 and the tube rotating device 4, is limited on both sides; the tube rotating device 4 is used to drive the stainless steel tube 10 with its stainless steel cover 11 mounted to rotate; the tube pressing device 5 is used to limit the downward movement of the stainless steel tube 10 with its stainless steel cover 11 mounted on the tube rotating device 4; the tube welding device 6 is used to weld the stainless steel cover 11 and the stainless steel tube 10 located on the tube rotating device 4; compared with welding by manually holding a welding gun, when welding using this utility model, Simply place the stainless steel tube 10 with the stainless steel cap 11 attached onto the inclined loading platform 1. The stainless steel tube 10 with the stainless steel cap 11 attached will automatically roll down onto the tube transfer device 4. The tube-stopping device 3 limits the two sides of the stainless steel tube 10 with the stainless steel cap 11 attached on the inclined loading platform 1 and the tube transfer device 4, which not only prevents the stainless steel cap 11 attached to both ends of the stainless steel tube 10 from falling off, but also prevents the stainless steel tube 10 from shifting, so as to better facilitate welding. The tube-pressing device 5 presses the stainless steel cap 11 attached to the tube transfer device 4. The stainless steel tube 10 of the steel cover 11 is limited downward. The stainless steel tube 10, on which the stainless steel cover 11 is mounted, is driven to rotate by the pipe rotating device 4. As the stainless steel tube 10 rotates continuously, the pipe welding device 6 welds the stainless steel cover 11 and the stainless steel tube 10 located on the pipe rotating device 4. This utility model can automatically weld the stainless steel cover 11 onto the stainless steel tube 10 by cooperating with the pipe pressing device 3, the pipe rotating device 4, the pipe pressing device 5, and the pipe welding device 6. This not only ensures stable and consistent welding quality, but also greatly reduces the safety risks for operators.

[0021] The tube-stopping device 3 includes two tube-stopping frames 31 symmetrically arranged on both sides of the inclined loading platform 1. Multiple tube-stopping beads 32 are rotatably connected to the two tube-stopping frames 31. The tube-stopping beads 32 can stop and limit the stainless steel tube 10 with the stainless steel cover 11 on both sides, while making it easier for the stainless steel tube 10 with the stainless steel cover 11 to roll on the inclined loading platform 1 and rotate on the tube-rotating device 4.

[0022] The tube rotating device 4 includes a tube rotating frame 41, a tube rotating active roller 42 rotatably connected to the tube rotating frame 41 in the front-back direction, a tube rotating power mechanism 43 for driving the tube rotating active roller 42 to rotate, and a tube rotating driven roller 44 rotatably connected to the rear of the tube rotating active roller 42 in the front-back direction. As the tube rotating power mechanism 43 drives the tube rotating active roller 42 to rotate, it can drive the stainless steel tube body 10 with the stainless steel cover 11 to rotate, so as to achieve full circle welding.

[0023] The tube transfer device 4 also includes a tube transfer lifting seat 45 slidably connected to the tube transfer frame 41 in the vertical direction, and a material feeding lifting power mechanism 46 for driving the tube transfer lifting seat 45 to slide.

The tube transfer driven roller 44 is rotatably connected to the tube transfer lifting seat 45. Compared with the need to manually pick up and place the welded stainless steel tube 10 onto the inclined material feeding platform 2, this utility model can automatically roll the stainless steel tube 10, which is located on the tube transfer device 4 and has completed the welding between the stainless steel cover 11 and the stainless steel tube 10, onto the inclined material feeding platform 2 by driving the tube transfer lifting seat 45 downward through the material feeding lifting power mechanism 46 after the welding between the stainless steel cover 11 and the stainless steel tube 10 is completed. This eliminates the need for manual picking and placing and can further improve the overall automation level.

[0024] The pipe pressing device 5 includes a pipe pressing frame 51, a pipe pressing lifting seat 52 slidably connected to the pipe pressing frame 51 in the vertical direction and located above the pipe rotating device 4, a pipe pressing lifting power mechanism 53 for driving the pipe pressing lifting seat 52 to slide, a front pipe pressing roller 54 rotatably connected to the bottom of the pipe pressing lifting seat 52 in the front-back direction and located directly above the rotating active roller 42, and a rear pipe pressing roller 55 rotatably connected to the bottom of the pipe pressing lifting seat 52 in the front-back direction and located directly above the rotating driven roller 44. The pipe pressing lifting power mechanism 53 is arranged in... On the pipe pressing frame 51, the output end of the pipe pressing lifting power mechanism 53 drives the pipe pressing lifting seat 52. When the stainless steel pipe 10 with the stainless steel cover 11 is rolled from the inclined loading platform 1 onto the pipe transfer device 4, the pipe pressing lifting power mechanism 53 drives the pipe pressing lifting seat 52 to slide downward and drives the front pipe pressing roller 54 and the rear pipe pressing roller 55 to limit the stainless steel pipe 10 downward. This can prevent the stainless steel pipe 10 from jumping and shifting position during the welding process, thereby better ensuring the welding quality.

[0025] The pipe welding device 6 includes a pipe welding frame 61, a pipe welding slide 62 slidably connected to the pipe welding frame 61 in the left-right direction, a pipe welding sliding power mechanism 63 for driving the pipe welding slide 62 to slide, and a pipe welding robot 64 mounted on the pipe welding slide 62. The pipe welding sliding power mechanism 63 is mounted on the pipe welding frame 61, and its output end drives the pipe welding slide 62. The pipe welding robot 64 of this invention is a Panasonic TM2000 welding robot, which is a known technology. Its specific structure will not be described in detail. It can perform multi-dimensional welding. By driving the pipe welding slide 62 to slide through the pipe welding sliding power mechanism 63, the position of the pipe welding robot 64 in the left-right direction can be adjusted, thereby allowing for better adjustment according to the specific welding position and enhancing its practicality.

[0026] Compared to having only one welding pipe robot 64, this utility model has two welding pipe slides 62 and two welding pipe sliding power mechanisms 63. The two welding pipe slides 62 are arranged side by side in the left-right direction. The output ends of the two welding pipe sliding power mechanisms 63 are respectively connected to drive one of the welding pipe slides 62. Each of the two welding pipe slides 62 is equipped with a welding pipe robot 64, which can simultaneously weld the two ends of the stainless steel pipe body 10 and the two stainless steel caps 11, which can greatly improve the overall welding processing efficiency.

[0027] A pipe-blocking device 7 is provided between the inclined loading platform 1 and the pipe-turning device 4. The pipe-blocking device 7 includes a pipe-blocking block 71 that is slidably connected in the vertical direction between the inclined loading platform 1 and the pipe-turning device 4, and a pipe-blocking power mechanism 72 for driving the pipe-blocking block 71 to slide. The pipe-blocking power mechanism 72 is set on the inclined loading platform 1, and the output end of the pipe-blocking power mechanism 72 drives the pipe-blocking block 71 to slide up and down. By driving the pipe-blocking block 71 to slide up and down through the pipe-blocking power mechanism 72, it is possible to better ensure that only one stainless steel pipe 10 with a stainless steel cover 11 is loaded onto the pipe-turning device 4 for welding each time.

[0028] The inclined loading platform 1 is provided with a loading stop 8 at the end away from the pipe rotating device 4. The loading stop 8 can prevent the stainless steel pipe 10 with the stainless steel cover 11 attached from falling off. The inclined unloading platform 2 is provided with a unloading stop 9 at the end away from the pipe rotating device 4. The unloading stop 9 can prevent the stainless steel pipe 10 with the stainless steel cover 11 welded off from falling off.

[0029] The tube-stopping device 3 is also used to limit the two sides of the stainless steel tube 10 with the stainless steel cover 11 welded on the inclined unloading platform 2. It can better ensure that the stainless steel tube 10 with the stainless steel cover 11 welded will not shift or fall off from the sides. It can also better ensure that the stainless steel tube 10 with the stainless steel cover 11 welded is arranged in an orderly manner on the inclined unloading platform 2, so as to better remove the stainless steel tube 10 with the stainless steel cover 11 welded from the inclined unloading platform 2.

[0030] Working principle:

[0031] Compared to manual welding with a handheld welding torch, this invention allows for welding by simply placing the stainless steel tube 10 with the stainless steel cap 11 attached onto the inclined loading platform 1. The stainless steel tube 10 with the cap 11 attached will automatically roll down onto the tube transfer device 4. The tube-stopping device 3 limits the two sides of the stainless steel tube 10 with the cap 11 attached, located on the inclined loading platform 1 and the tube transfer device 4. This not only prevents the stainless steel caps 11 attached to both ends of the stainless steel tube 10 from falling off, but also prevents the stainless steel tube 10 from shifting, thus facilitating better welding. The device 5 limits the downward movement of the stainless steel pipe 10, which is fitted with a stainless steel cap 11, located on the pipe rotating device 4. The pipe rotating device 4 drives the stainless steel pipe 10, which is fitted with a stainless steel cap 11, to rotate. As the stainless steel pipe 10 rotates continuously, the pipe welding device 6 welds the stainless steel cap 11 and the stainless steel pipe 10 located on the pipe rotating device 4. This utility model can automatically weld the stainless steel cap 11 onto the stainless steel pipe 10 through the cooperation of the pipe-stopping device 3, the pipe rotating device 4, the pipe-pressing device 5, and the pipe welding device 6. This not only ensures stable and consistent welding quality but also greatly reduces the safety risks to operators.
