Embodiment 1

[0047] Embodiment 1: as figure 1 As shown, a steel pipe and flange splicing and processing integrated machine includes a working platform 1 and a support bracket 6 arranged on the working platform 1 for supporting the steel pipe. A first welding device 2 is provided at one end of the working platform 1 . The top surface of the working platform 1 is provided with a first guide rail 4 extending from the first welding device 2 to the other end of the working platform. A first mounting plate 5 is slidably provided on the first guide rail 4 . A horizontal moving device for pushing the first mounting plate is provided between the working platform 1 and the first mounting plate 5 . The second welding device 3 is arranged on the first mounting plate 5 . The first welding device 2 and the second welding device 3 are provided with a flange fixing template 15 and the two flange fixing templates are arranged opposite to each other. A steel pipe cutting device 7 that can move along the...

Embodiment 2

[0079] Example 2, such as figure 1 As shown, a steel pipe and flange splicing and processing integrated machine includes a full-circle mold 8 . The full circle mold 8 comprises two semicircular hoops arranged symmetrically, and the two ends of the hoops are connected by bolts. Refer to Embodiment 1 for the rest of the structure of this embodiment.

[0080] Compared with the processing technology in Example 1, the specific processing technology of a steel pipe and flange splicing and processing integrated machine in this embodiment is different in that:

[0081] Before the steel pipe and the flange are welded, specifically before the steel pipe and the flange are connected by spot welding, the end of the steel pipe is first rounded by the full circle mold, and the full circle mold is rounded after completing the rounding of the end of the steel pipe. The mold remains on the end of the steel pipe until the inner and outer sides of the steel pipe and the flange are welded and r...

Abstract

The invention discloses an integrated steel pipe and flange splicing and machining machine and a machining process thereof and aims to provide an integrated steel pipe and flange splicing and machining machine which can improve the manufacturing precision and the production efficiency and reduce the labor intensity and is high in steel pipe and flange welding quality and a machining process of the machine. The integrated steel pipe and flange splicing and machining machine comprises a working platform, and a supporting bracket which is arranged on the working platform and is used for supporting a steel pipe, wherein one end of the working platform is provided with a first welding device; a first guide rail which extends to the other end of the working platform is arranged on the top of the working platform; a first mounting plate is arranged on the first guide rail in a sliding mode; a second welding device is arranged on the first mounting plate; and flange fixing templates are arranged on the first welding device and the second welding device. The machining process comprises the following steps of: lifting the steel pipe to the supporting bracket, and fixing the flange to a flange fixing template; and welding annular gaps of the inner and outer side faces of the steel pipe and the flange through the first welding device and the second welding device.

Description

technical field [0001] The invention relates to a steel pipe and flange splicing processing equipment, in particular to a steel pipe and flange splicing processing integrated machine and its processing technology. Background technique [0002] The current splicing process of the steel pipe and the flange is roughly as follows. First, the steel pipe is hoisted to a large cutting machine, and the steel pipe is cut to length. Next, hoist the cut steel pipe to the special rounding equipment for rounding; then, hoist the rounded steel pipe on the welding platform, and install the flanges on both ends of the steel pipe on the welding platform. Finally, the two ends of the steel pipe are aligned with the flange; after the alignment, the flanges at both ends are welded to the steel pipe by means of ring welding. For example, Chinese Patent Publication No. CN201728497U, the publication date was February 2, 2011. The name of the invention is an automatic butt joint device for flanges...
