Embodiment 1

[0043] refer to Figure 1-10 As shown, the welding device used in step S1 includes a load-bearing plate 1 and a welding torch 7. The upper surface of the load-bearing plate 1 is fixed on the first support plate 13 for supporting the total sleeve 3, and the first support plate 13 is provided with a The chute of cylinder 3 limit sliding. The upper surface of the load-bearing plate 1 fixes the first support frame 11, the second support plate 12 and the second support frame 14, and the first support frame 11 is provided with a ring for driving the total sleeve 3 to rotate so that the total sleeve and the lower pipe can be rotated. Rotary mechanism welded on half side. There is a chute on the second support plate 12, and the first rack 4 is slidably connected through the chute limit. The first rack 4 is provided with a pushing mechanism for pushing the total sleeve 3 so as not to be manually pushed. The support frame 14 is provided with a welding mechanism for automatically weldi...

Embodiment 2

[0055] It is basically the same as Embodiment 1. In this embodiment, the load-bearing plate 1 is provided with a discharge mechanism for intermittently discharging the lower pipe 33, the support block 16 is fixed on the load-bearing plate 1, and the support block 16 is fixed for storing the lower pipe 33. Store bucket 61. The supporting block 16 is connected with a disc 6 for fixed axis rotation, and there are multiple sets of slots for intermittently discharging the lower pipes 33 on the disc 6 . The support block 16 is provided with an inclined surface for the sliding of the lower pipe 33, and the support block 16 is provided with a chute for the lower pipe 33 to be sleeved on the support sleeve 31, and the third rotating rod 62 is coaxially fixed on the disk 6, and the The third disc wheel 63 is fixed on the three rotating rods 62 .

[0056] The discharge mechanism includes a third support frame 17 and a second belt 64 , the third support frame 17 is fixed on the support b...

Embodiment 3

[0059] It is basically the same as the second embodiment. In this embodiment, the second support frame 14 is provided with a fixing mechanism for fixing the lower pipe 33 along the support sleeve 31 with the main sleeve 3. The fixing mechanism includes fixing on the second support The third support plate 18 on the frame 14. A fifth rotating rod 81 is connected to the third supporting plate 18 for fixed axis rotation, and a third bevel gear 82 intermittently meshing with the second incomplete bevel gear 73 is fixed on the arc profile of the fifth rotating rod 81 . The third support plate 18 is provided with a chute and is slidably connected with the second rack 8 meshing with the third bevel gear 82 through the chute. A fixing block 83 for fixing the cylinder 31 and the overall sleeve 3 . The lower surface of the second rack 8 fixes the baffle plate 85, and the second support frame 14 is provided with a sliding groove 84 cooperating with the baffle plate 85, and a spring 86 is...

Abstract

The invention discloses a boiler header welding process. The boiler header welding process comprises the following steps that S1, firstly, a bearing rod of a welding device and a main sleeve are fixed through a fixing mechanism; s2, then a motor is started, an output shaft drives a first incomplete bevel gear, a first disc wheel, a first bevel gear and a first rotating rod to rotate, and therefore when a crank and a supporting rod rotate, a sliding plate drives a first rack to slide up and down in a reciprocating mode; s3, when a first rack slides up and down in a reciprocating mode, a first gear rotates in a reciprocating mode, and a bearing rod drives a main sleeve to rotate synchronously through cooperation of a pin key; and S4, when the first rack slides downwards, the wedge block slides in the direction of the first supporting frame along the inclined sliding groove, so that the pushing block is not matched with the clamping groove, when the first rack slides upwards, the wedge block slides in the direction away from the first supporting frame along the inclined sliding groove, the pushing block is matched with the clamping groove due to the limiting effect of the limiting rod, and therefore after welding of the front half side and the rear half side is completed, the wedge block slides in the direction away from the first supporting frame. And the main sleeve is pushed forwards, so that the lower-stage pipe can be conveniently welded on the next branch sleeve.

Description

technical field [0001] The invention relates to the technical field of header welding, in particular to a boiler header welding process. Background technique [0002] The header (also known as the header) is an important part of the boiler. It is divided into an upper header and a lower header. The header is a pipe fitting for mixing the working fluid of the boiler and ensuring uniform heating of the working fluid. The working fluids meet here and are then distributed to the tubes of the next stage, which can reduce the heat deviation and optimize the heat absorption and flow of the working fluid, the cooling of the boiler, and the thermal efficiency of the boiler; [0003] At present, manual welding is generally used for the intermittent welds on the front wall panels of containers. However, due to the large number of welds, this leads to a large workload and low welding efficiency; it is done manually, and there are many subjective factors, and the length and interval of t...
